Operator: I will now hand the call over to Dr. Tony Coles, chairperson and CEO of Cerevel, to provide an overview of our achievements and outlook. Thanks, Matt, and good morning, everyone, and thank you for joining us for our fourth quarter and full year 2022 business results call. Cerville aspires to become the premier neuroscience company, and we continue to have great momentum towards achieving that distinction. 2022 was a particularly productive and successful year as we remain steadfast and focused on our mission to transform what is possible in neuroscience.

Speaker 2: I will now hand the call over to Dr. Tony Coles, Chairperson and CEO of Cerebell, to provide an overview of our achievements and outlook. Thanks, Matt, and good morning, everyone. Thank you for joining us for our fourth quarter and full year 2022 Business Results Call. Cerebell aspires to become the premier neuroscience company and we continue to have great momentum towards achieving that distinction. 2022 was a particularly productive and successful year as we remain steadfast and focused on our mission to transform what is possible in neuroscience. We delivered positive results in our Imraquithine blood pressure trial in December , raised $599 million in new capital at mid-year to extend our cash runway into 2025 and started the year with positive anxiety data in Duregabat marking an important set of achievements for the organization. Let me first specifically highlight Imraquithine.

Operator: We delivered positive results in our Imrakhaline blood pressure trial in December, raised $59 million in new capital at midyear to extend our cash runway into 2025, and started the year with positive anxiety data in Derigabat, marking an important set of achievements for the organization. Let me first specifically highlight Imrakw thee, our M4 Selective Positive Alastric Modulator or Pan.

Dr. Tony Coles: We are especially pleased with the momentum of this program, which remains our top priority. A robust phase two empower program for adults living with schizophrenia is enrolling well and remains on track for a data readout in the first half of 2024. We know that the patient need in this area is tremendous. More than 2 million people in the U.S. live with schizophrenia, and the disease touches the lives of caregivers and communities at large, with patients more likely to experience homelessness, addiction, and death by suicide.

Speaker 2: our M4 selective positive allosteric modulator or PAM. We are especially pleased with the momentum of this program, which remains our top priority. Our robust phase two and power program for adults living with schizophrenia is enrolling well and remains on track for a data readout in the first half of 2024. We know that the patient need in this area is tremendous. More than two million people in the US live with schizophrenia and a disease touches the lives of caregivers and communities at large with patients more likely to experience homelessness, addiction, and death by suicide. We continue to prioritize this important phase two program and the completion of the other necessary registration enabling activities, including an open label extension trial in order to bring this potentially transformative medicine to patients as quickly as possible. We also proactively took an important step toward registration by conducting and concluding our ambulatory blood pressure monitoring.

Dr. Tony Coles: We continue to prioritize this important phase two program and the completion of the other necessary registration enabling activities, including an open-label extension trial, in order to bring this potentially transformative medicine to patients as quickly as possible. We also proactively took an important step toward registration by conducting and concluding our ambulatory blood pressure monitoring trial early in clinical development. The positive results from this important risk-mitigating trial, which were announced in December 2022, provided clear evidence that RACAVine does not induce a sustained increase in blood pressure with chronic dosing in people living with schizophrenia.

Dr. Tony Coles: Driven by our strong belief in the differentiated advantages of a targeted, selective, informed mechanism, we are also exploring a miraculine for the treatment of Alzheimer's disease psychosis, a condition that affects more than 40% of people living with Alzheimer's disease.

Dr. Tony Coles: We were pleased to receive fast-track designation for a miraculum from the FDA for the treatment of hallucinations and delusions associated with Alzheimer's disease and psychosis, and we initiated a phase one healthy elderly volunteer trial to support development for this indication at the end of last year. Our work with Imrakavine and schizophrenia and ADP, however, is only one part of the Cerebel story. Across our broad pipeline, we are also advancing therapies for other serious neurological conditions by targeting new pathways with novel selective approaches, which is the central unifying theme underlying Cerevel.

Speaker 2: is only one part of the cerebral story. Across our broad pipeline, we are also advancing therapies for other serious neurological conditions by targeting new pathways with novel selective approaches, which is the central unifying thesis underlying cerebral. As such, I'd now like to highlight, Derrick Abat, our Alpha-235 selective GABA A receptor PAM,

Dr. Tony Coles: As such, I'd now like to highlight Derigabat, an Alpha-235 Selective Gaba A receptor PAM in development for both epilepsy and panic disorder. We're currently conducting the realized trial, a phase two proof of concept trial in focal epilepsy. Epilepsy is the fourth most common neurological disorder, affecting one out of every 26 people.

Speaker 2: in development for both epilepsy and panic disorder. We're currently conducting the Realized Trial, a phase two proof of concept trial in focal epilepsy. Epilepsy is the fourth most common neurological disorder, affecting one out of every 26 people. Our Realized Trial seeks to advance the Rigobat in this important indication and address an area of tremendous unmet need for patients who need better control of their seizures. As Ray will discuss in more detail, enrollment has been affected by post COVID headwinds that are causing clinical trial delays across the industry.

Dr. Tony Coles: Our realized trial seeks to advance derogabat in this important indication and address an area of tremendous unmet need for patients who need better control of their seizures. However, as Ray will discuss in more detail, enrollment has been affected by post-COVID headwinds that are causing clinical trial delays across the industry. Given these landscape challenges, we have announced today that we no longer expect data for this trial in 2023. As we've recently done with Tavapidon, we are conducting a thorough review of the realized sites and the clinical trial timeline and are actively implementing robust mitigation plans to complete this trial.

Speaker 2: Given these landscape challenges, we have announced today that we no longer expect data for this trial in 2023. As we've recently done with Tavapodon, we are conducting a thorough review of the realized sites and the clinical trial timeline and are actively implementing robust mitigation plans to complete this trial. We will provide an update on that revised timeline by mid-year. We have tremendous confidence in the potential of Derigabat to address important unmet medical needs, not only for epilepsy, but in the potential treatment of anxiety-related disorders, given its selectivity and its avoided something alpha-1 receptors subunit, which we believe is the main driver of the occurrence of side effects that plays as a daisopiece. It was this time last year that we shared our positive top-line data from our Derigabat Phase 1 healthy volunteer trial in a panic-separated open to model.

Dr. Tony Coles: We will provide an update on that revised timeline by mid-year. We have tremendous confidence in the potential of Derigabat to address important unmet medical needs, not only for epilepsy, but for the potential treatment of anxiety-related disorders, given its selectivity and its avoidance of the alpha-1 receptor subunit, which we believe is the main driver of the occurrence of side effects that plague benzodiazepines. It was this time last year that we shared our positive top-line data from our Derigabat phase one healthy volunteer trial in a panic symptom model. These results provide strong evidence of Derivats potential as a well-tolerated and differentiated daily maintenance treatment for anxiety-related disorders, which would be an important breakthrough in the clinical treatment of anxiety.

Speaker 2: These results provide strong evidence of direct events potential as a well-tolerated and differentiated daily maintenance treatment for anxiety-related disorders, which would be an important breakthrough in the clinical treatment of anxiety. We're enthusiastic about initiating our Phase 2 trial in panic in the second quarter of this year, and that remains on track as well. As we begin 2023, our focus is on execution and continued fiscal discipline as we headed into a data-rich 2024 when we expect seven mid to late-stage data readouts, starting with our two Phase 2 trials of immoracle the Infraskitz-Afrinia in the first half of next year. As of the end of 2022, we had $950 million of cash resources, which we expect will fund our operations into 2025, and we continue to look for opportunities to be creative in our ongoing efforts to maximize the value of our pipeline.

Dr. Tony Coles: We're enthusiastic about initiating our phase two trial and panic in the second quarter of this year, and that remains on track as well. As we begin 2023, our focus is on execution and continued fiscal discipline as we head into a data-rich 2024, when we expect seven mid-to-late-stage data readouts, starting with our two phase two trials of Imraklidine for schizophrenia in the first half of next year. As of the end of 2022, we had $950 million in cash resources, which we expect will fund our operations into 2025.

Dr. Tony Coles: And we continue to look for opportunities to be creative in our ongoing efforts to maximize the value of our pipeline as we target our spending on the highest priority programs. Finally, I also want to acknowledge that our president, Abe Cese, will be leaving Cerville as of March 9 to pursue an exciting CEO opportunity at a private biotechnology company. I went to publicly thank Abe for his leadership and many contributions to Sarval, and we all wish him well in his next endeavor.

Speaker 2: as we target our spending on the highest priority programs. Finally, I also want to acknowledge that our president, H.C.S.A. will be leaving Cerebel as of March 9 to pursue an exciting CEO opportunity at a private biotechnology company. I want to publicly thank A for his leadership and many contributions to Cerebel, and we all wish him well in his next endeavors. With that, let me now turn the call over to Dr. A. Sanchez, our chief medical officer, to provide some added color regarding our lead programs, right? Thank you, Tony, and good morning to all of you.

Dr. Tony Coles: With that, let me now turn the call over to Dr. Ray Sanchez, our chief medical officer, to provide some added color regarding our lead programs. Ray. Thank you, Tony, and good morning to all of you. As Tony just mentioned, 2022 was a productive year that will allow us to continue to unlock the valleys and the potential of our pipeline to treat some of the most challenging neuroscience diseases. Let's first turn to him quickly.

Speaker 3: As Tony just mentioned, 2022 was a productive year that will allow us to continue to unlock the values and the potential of our pipelines to treat some of the most challenging neuroscience diseases. Let's first turn to our rapidings. Our robust phase two trials are enrolling very well in our own track. We expect this momentum to continue and look forward to data in the first half of next year.

Ramiro Sanchez: Our robust phase two trials are enrolling very well and are on track. We expect this momentum to continue and look forward to data in the first half of next year. We are observing that the ongoing inpatient trials for Imrakli are not facing the same type of headwinds that we were seeing for trials mostly in the outpatient setting. These two adequately powered three-arm trials, called Empower 1 and Power 2, are being conducted worldwide and will each randomize 372 adults living with schizophrenia and experiencing an acute exacerbation of psychotic symptoms. The first trial will test raclitine 10 milligrams and 30 milligrams once daily versus placebo, and the second trial will test raclitine 15 milligrams and 30 milligrams once daily versus placebo.

Speaker 3: We are observing that the ongoing inpatient trials for immorality are not facing the same type of headwinds that we were seeing for trials mostly in the outpatient setting. These two adequately powered three-arm trials called Empower 1 and Empower 2 are being conducted worldwide and will each randomized 372 adults living with schizophrenia and experiencing an acute exacerbation of psychotic symptoms. The first trial will test in raclidine 10 milligrams and 30 milligrams one daily versus placebo, and the second trial will test in raclidine 15 milligrams and 30 milligrams one daily versus placebo. We design these trials to potentially meet the criteria necessary to service pivotal trials.

Ramiro Sanchez: We design these trials to potentially meet the criteria necessary to serve as pivotal trials, based on what we expect the FDA will evaluate in a registrational package. Running these two trials in parallel enables us to fully explore the therapeutic dose range of amacodyne while minimizing the number of treatment arms, with the hope of reducing the variability observed in clinical trials and the placebo response. In order to potentially accelerate a registrational package for enraglating in schizophrenia, we have moved forward with the initiation of a 52-week open-label safety extension trial known as Empower 3. This program is a cornerstone for Saraville, and I am very pleased with our progress.

Speaker 3: based on what we expect the FDA will evaluate in a registration package. Running these two trials in parallel enables us to fully explore that therapeutic dose range of enracodine while minimizing the number of treatment arms with the hope of reducing the variability observed in clinical trials and the placebo response. In order to potentially accelerate a registration package for enracodine schizophrenia, we have moved forward with the initiation of a 52-week open-label safety extension trial known as Empower 3. This program is a cornerstone for CERVAL and I am very pleased with our progress. Our momentum was bolstered by the positive results we announced in December in an ambulatory blood pressure monitoring trial, which confirmed that enracodine does not cause a sustained increase in blood pressure with chronic dosing in people living with schizophrenia, and provided an important risk mitigation step in the continued development of this program. Our decision to generate these data earlier in clinical development speaks to the benefits of our thoughtful and proactive approach, and we are happy to have this important milestone behind us.

Ramiro Sanchez: Our momentum was bolstered by the positive results we announced in December in an ambulatory blood pressure monitoring trial, which confirmed that Racklandine does not cause a sustained increase in blood pressure with chronic dosing in people living with schizophrenia and provided an important risk mitigation step in the continued development of this program. Our decision to generate these data earlier in clinical development speaks to the benefits of our thoughtful and proactive approach, and we are happy to have this important milestone behind us for this vital pipeline program.

Ramiro Sanchez: We also continue to progress our Phase 1 Healthy, Elderly Volunteer Trial to support the development of Imraklidine and Alzheimer's disease psychosis. The symptoms of ADP, including hallucinations and delusions, can be incredibly distressing for the patient and their loved ones and can drive fear and stigma around the disease.

Speaker 3: for this vital pipeline program. We also continue to progress our phase one healthy elderly volunteer trial to support the development of emiracling in Alzheimer's disease psychosis. The symptoms of ADP, including hallucinations and delusions, can be incredibly distressing for the patient and their loved ones and can drive fear and stigma around the disease. It is our hope that by selectively targeting the M4 pathway, we can harness anti-sacotic benefits while minimizing the side effects associated with other musterineg agents. The results of the healthy elderly volunteer trial will guide our clinical development plan in Alzheimer's disease psychosis. Turning now to the Rigabet, our Alpha-235 Selective GABA A receptor, positive-alosteric modulator, currently in development for epilepsy and panning disorder. We believe the Rigabet has the potential for both anti-epileptic and angiolidic activity comparable to currently available benzodiazepines, but with reduced side effects that results from the non-selective mechanism of benzodiazepines. Rigabet's novel mechanism of action and expected tolerability profile provides the potential for a new treatment option that can also be used chronically addressing a significant unmet need in this area. Our phase two realized trial is progressing, although as Tony mentioned, it has been impacted by the headwinds that are causing delays in a broad range of clinical trials.

Ramiro Sanchez: It is our hope that by selectively targeting the M4 pathway, we can harness antipsychotic benefit while minimizing the side effects associated with other muscular renegades. The results of the healthy elderly volunteer trial will guide our clinical development plan in Alzheimer's disease. Turning now to De Rigavette, our Alpha 235 selective GABAA receptor, positive allostericuric modulator currently in development for epilepsy and panicked, We believe Derrigaba has the potential for both anti-epileptic and angiolidic activity comparable to currently available benzodiaz but with reduced side effects that results from the non-selective mechanism of benzodiaz, Doriabat's novel mechanism of action and expected tolerability profile provides the potential for a new treatment option that can also be used chronically, addressing a significant unmet need in this area.

Ramiro Sanchez: Our phase two realized trial is progressing, although, as Tony points out, it has been impacted by the headwinds that are causing delays in a broad range of clinical trials. We have validated the industry-wide scope of these delays via a thorough review of peer trial timelines in clinical trials.gov and supporting data available in CRO and other industry analyses, which corroborate our own direct experience. In addition, Dorigabet's effectiveness has been affected by the use of excluded concomitant medications in the target population.

Speaker 3: We have validated the industry wide scope of the utilize via a thorough review of peer trial time-lancing, clinical trials.gov, and supporting data available in CRO and other industry analyses, which corroborate our own direct experience. In addition, Gerritaba had been affected by the use of excluded concomitant medications in the target population. As a result of these factors, we no longer expect data this year and are in the process of conducting a thorough review of the trial time lens. We will return with an update by mid-year. We are steadfast in our commitment to advance its important therapy. We have an experienced team that is continually deploying new medications to address the headwinds associated with enrollment challenges, while importantly, remaining focused on data quality. We added trial sites in new countries last year and we planned to add additional sites in the Asia Pacific region where our team has strong historical experience. We are encouraged in our ongoing efforts by the over 90% role over rate we have seen today into the realize open label extension, which speaks to the potential benefit to patients of Gerritaba in vocal epilepsy.

Ramiro Sanchez: As a result of these factors, we no longer expect data this year and are in the process of conducting a thorough review of the trial time lens. We will return with an update by mid-year. We are steadfast in our commitment to advance this important therapy. We have an experienced team that is continually deploying new mitigations to address the headwinds associated with enrollment challenges, while importantly, remaining focused on data quality. We added trial sites in new countries last year, and we plan to add additional sites in the Asia-Pacific region, where our team has strong historical experience.

Ramiro Sanchez: We're encouraged in our ongoing efforts by the over 90% rollover rate we have seen to date into the realized open label extension, which speaks to the potential benefit to patients of DRIGBAT in Focal EPP. We're excited about expanding the potential applications of Deregabath through the initiation of our phase two trial for panic disorder in the second quarter of this year. Panic episodes present with a constellation of symptoms, including a rapid, pounding heart rate, a sense of impending doom, weakness, dizziness, disorientation, and even chest pain, making some people feel like they're experiencing a heart attack.

Speaker 3: We're excited about expanding the potential applications of DurigaBat through the initiation of our Phase II trial and panic disorder in the second quarter of this year. Panic episodes present with a constellation of symptoms, including a rapid pounding heart rate, sense of impending doom, weakness, dissonance, disorientation, and even chest pain, making some people feel that they're experiencing a heart attack. We believe DurigaBat has the potential to provide anxiety-benefit while minimizing the limiting side effects of non-selective GABA-APAN, such as benzodiazepines. If correct, DurigaBat may provide a well-tolerated, daily option in the treatment of panic attacks compared with the sparing and episodic use of benzodiazepines due to side effects. This would potentially be paradigm shifting for the important anxiety-related disorder in the experience of these patients in terms of living with panic disorder. Turning now to Tabapidon, our D1-D5 partial eigenstin development for Parkinson's disease, as both a model therapy and a jump in treatment. The number of Parkinson's cases is expected to double worldwide from a proxy of 6 million in 2015 to 12 million in 2014. We believe that Tabapidon could serve as a preferred model therapy early in disease with a potentially reduced side effect burden compared to the 16 therapies. For the more advanced Parkinson's patient, Tabapidon could be a preferred adjunct treatment with Aldoba.

Ramiro Sanchez: We believe Rigabat has the potential to provide anxuletic benefit while minimizing the limiting side effects of non-selective GABA APAMs, such as Benzavaz. If correct, Jorigabat may provide a well-tolerated daily option in the treatment of panic attacks compared with the sparing and episodic use of benzodiazepines due to cytosidic. This would potentially be paradigm-shifting for this important anxiety-related disorder and could transform the experience of these patients in terms of living with panic.

Ramiro Sanchez: Turning now to Tababidon, our D1D5 partial agonist in development for Parkinson's disease as both a monotherapy and a junk of treatment. The number of Parkinson's cases is expected to double worldwide from approximately 6 million in 2015 to 12 million in 2040. We believe that Tabapidon could serve as a preferred monotherapy early in the disease with a potentially reduced side effect burden compared with existing therapy.

Ramiro Sanchez: For the more advanced Parkinson's patient, Tabapidon could be a preferred adjunctive treatment with El Dopa due to its longer half-life and potentially improved tolerability profile and reduced incidence of dyskinesias, with the goal of allowing for 24-hour motor symptom control and delaying the need for El Dopa dose. As Tony discussed, all three of Aperton's Aperton-based trials, known collectively as the tempo trials Given the challenges in the clinical trial environment across the industry, we announced in November that we were conducting a thorough review of this program and its timeline.

Speaker 3: due to its longer half-blip and potentially improved tolerability profile and reduced incidence of dyskinesias with the goal of allowing for 24-hour motor symptom control and delaying the need for aldopa-dosis collation. As Tony discussed, all three of our Tvapinon-based three trials known as collectively as the temple trials are ongoing, along with the corresponding open label extension in which we are also seeing high-roll over rates of over 90 percent. Given the challenges in the clinical trial environment across the industry, we announced in November that we were conducting a thorough review of this program in its timelines. With the deployment of new medications, including the expected opening of new sites in the Asia Pacific region, we now expect data for Temple 3 in mid-2024 and data for Temple's 1 and 2 in the second half of 2024. Our other D1-D5 program, CBL 871, which we are pursuing in the novel indication of dementia-related apathy, is also expected to read out in the second half of 2024.

Ramiro Sanchez: With the deployment of new mitigations, including the expected opening of new sites in the Asia-Pacific region, we now expect data for Tempo 3 in mid-2024 and data for Tempos 1 and 2 in the second half of 2020.

John J. Renger: Our other D1D5 program, CBL 871, which we are pursuing in the novel indication of dementia-related apathy, is also expected to read out in the second half. We have an experienced team that is navigating and addressing the challenges of the external environment as we continue to advance our broad and deep pipeline of neuroscience. We remain focused on maintaining the quality of the clinical trials we conduct and, importantly, not compromising the collection of data for the sake of expedients.

Speaker 3: We have an experienced team that is navigating and addressing the challenges of the external environment as we continue to advance our broad and deep pipeline of neuroscient facets. We remain focused on maintaining the quality of the clinical trials we conduct and importantly, not compromising the collection of data for the sake of expediency. I'm looking forward to updating you on our progress as we look ahead to data from 7 mid-to-late stage clinical trials in 2024. With that, Dr. John Ranger, our chief scientist of officer will provide an update on our early stage portfolio. John . Thank you, Ray. Good morning, everyone. 2022 is a very productive year for our research and early clinical programs. I'd like to begin by speaking to our selective capital of your receptor antagonist, or Cora, CBL-354. This exciting new mechanism of action has shown promise pre-clinically in depression, anodonia and opioid withdrawal models.

John J. Renger: I'm looking forward to updating you on our progress as we look ahead to data from seven mid to late stage clinical trials in 2024. With that, Dr. John Renger, our chief scientific officer, will provide an update on our early stage portfolio. Thank you, Ray. Good morning, everyone.

John J. Renger: 2022 is a very productive year for our research and early clinical program. Let's begin by speaking about our selective cap opioid receptor antagonist, or CBL 354. This exciting new mechanism of action is shown promising preclinically in depression, anidonia, and opioid withdrawal models.

John J. Renger: We also recently saw a demonstration of clinical proof of concept in a phase two major depressive disorder trial completed by one of our peers. Additionally, our recent scientific presentations revealed the receptor subtype selectivity of our compound, CBL 354, and a non-human primate pet receptor occupancy study. These studies demonstrated dose-dependent target engagement of 354, with at least ten-fold more potent binding at caper receptors than the new receptor. This data set will be followed up and confirmed by our planned human pet receptor occupancy trial, examining Kappa and Voreceptor susceptibility of CBL 354 in humans. We believe that the clinical exploration of pet receptor occupancy binding of CBL 354 will be important to inform appropriate dose ranging and multiple potential indications.

Speaker 2: We also recently saw a demonstration of clinical proof of concept in a phase two major depressive disorder trial, completed by one of our peers. Our recent scientific presentations have revealed the receptor subtext selectivity of our compound CBL354 and nonhuman primate PET receptor occupancy studies.

Speaker 2: These studies demonstrated dose-dependent targeting engagement of 354, or at least a 10-fold more potent binding at cap receptors than mere receptors. This data set will be followed up and confirmed by our Plan Human Pet Receptor Agency trial, examining capa and new receptor-subtivian CVL354 in human. We believe that the clinical exploration of pet receptor occupancy binding of CVL354

John J. Renger: As Tony mentioned, we believe strongly in the potential of enforced activity based upon our clinical experience with Amarquaheen. As we have disclosed previously, we're advancing our selective M4 full agonist program, and we have identified a clinical trial candidate molecule in 2022. Our current understanding of the science behind receptor selectivity strongly supports our confidence in the ability to apply a full agonist pharmacological approach that may enable indication expansion beyond those that may be most aligned to amyaclidine, underpinning our excitement about the creation of an M4 selectivity-based therapeutic franchise.

Speaker 2: will be important to inform appropriate dose ranging and multiple potential indications. As Tony mentioned, we believe strongly in the potential of M4 selectivity based upon our clinical experience with MRI codeine. As we have disclosed previously, we are advancing our selected M4 full agonist program, and we have identified a clinical lead candidate in molecule in 2022. Our current understanding of the science behind receptor selectivity strongly supports our confidence and the ability to apply a full agonist pharmacological approach that may enable indication expansion beyond those that may be most aligned to MRI codeine, underpinning our excitement about the creation of an M4 selectivity based therapeutic franchise. Go forward to further updating our progress on this program in the near future. I want to sincerely thank the teams who are hard at work in early stage research and development.

John J. Renger: I look forward to further updating you on our progress on this program in the near future. I want to sincerely thank the teams who are hard at work in early stage research and development. As you know, we are purpose-built to unravel the mysteries of the brain to treat neuroscience diseases, and our scientists are passionate, experienced, and skilled at what they do. I'm excited about what promises to be a very productive 2023. I'm not going to hand it over to Sarah Wells' interim chief financial officer, Mark Bonerader, who will review our financial performance for the fourth quarter and the full year. Thank you, John. Good morning, everyone.

Speaker 3: As you know, we are a purpose built to unravel the mysteries of the brain to treat neuropsychic diseases, and our scientists are passionate, experienced, and skilled at what they do. I'm excited about what promises to be a very productive 2023. I'm not going to hand it over to our cerebells, interim chief financial officer, Mark Bohnrater, who will review our financial performance for the fourth quarter in the full year. Mark. Thank you, John . Good morning, everyone. I'm pleased to provide an overview of cerebell's strong financial position. I'll start by discussing our cash position in 2022 financial results, and then I'll spend a few moments on our financial outlook. Importantly, we will continue to exercise physical discipline as we target our investments and spend on the highest value opportunities in our pipeline. As of December 31, 2022, our cash cash equivalent in Markable Securities told $950 million, bolstered by the $599 million financing completed last August , reinforcing cerebells strong financial position. Our cash resources are expected to fund our operations into 2025, which will support us through the 7 mid to late stage data readouts we expect in 2024, and allow us to achieve the next inflection point for each of our lead programs. For full year 2022, total operating expenses were approximately $368 million, which includes our D-expense of $280 million, and GNA Expense of $88 million. Our D-expense for 2022.

Mark Bodenrader: I'm pleased to provide an overview of several strong financial results. I'll start by discussing our cash position in 2022 and then I'll spend a few moments on our financial out. Importantly, we will continue to exercise fiscal discipline as we target our investments and spend on the highest value opportunities in our pipeline. As of December 31st, 2022, our cash, cash equivalents, and marketable securities totaled $950 million, bolstered by the $59 million financing completed last August, reinforcing Saraville's strong financial position.

Mark Bodenrader: Our cash resources are expected to fund our operations into 2025, which will support us through the seven mid to late stage data readouts we expect in 2024 and allow us to achieve the next inflection point for each of our lead programs. For full year 2022, total operating expenses were approximately $368 million, which includes R&D expense of $280 million and G&A expense of $88 million. R&D expense for 2022 increased by approximately $118 million over 2021, which was primarily due to investment in our Ranclidine program, including the initiation of our robust phase two trials for schizophrenia.

Speaker 3: increased by approximately $118 million over 2021, which was primarily due to investment in our in Miracletine program, including the initiation of our robust phase two trials in schizophrenia, the continued advancement of our other later stage clinical programs, investment in our early discovery efforts, and personnel in other infrastructure costs supporting the continued growth and expansion of our pipeline. R&D expense for 2022 also included $18.2 million of equity-based compensation expense versus $9.2 million for 2021. GNA expense for 2022 increased by approximately $29 million over 2021, primarily due to higher personnel costs and other costs that support organizational growth in the advancement of our programs. GNA expense for 2022 also included $20.6 million of equity-based compensation expense.

Mark Bodenrader: The continued advancement of our other later stage clinical programs, investment in our early discovery efforts, and personnel and other infrastructure costs supporting the continued growth and expansion of our pipeline. R&D expense for 2022 also included $18.2 million of equity-based compensation expense versus $9.2 million for 2021. G&A expense for 2022 increased by approximately $29 million over 2021, primarily due to higher personnel costs and other costs to support organizational growth in the advancement of our program. GNA expense for 2022 also included $20.6 million of equity-based compensation, relative to $14.7 million for 2021.

Mark Bodenrader: For 2023, we will continue to proactively review our operating, Adjust our spending plans commensurate with our shift in trial timelines and monitor for opportunities to manage and gate spend as appropriate. And as Tony mentioned, we'll continue to invest in our pipeline where we believe there's long-term value creation potential. Looking forward, we expect our GNA expenses to remain relatively consistent for 2023 as compared to the fourth quarter of 2022, and we will focus our R&D spending on our top priorities, including advancing our ongoing comprehensive Phase 2 program for Imraklidine schizophrenia, in the recently initiated Phase 1 trial of Imrachlidine in healthy elderly volunteers to support the development in Alzheimer's disease psychosis, initiating our Phase 2 trial for Derigabat and Panic Disorder, and continuing the advancement of our other lead programs.

Speaker 3: relative to $14.7 million for 2021. For 2023, we will continue to proactively review our operating plan, adjust our spending plans, commensurate with our shift in trial timelines, and monitor for opportunities to manage and gate spend as appropriate. And as Tony mentioned, we will continue to invest in our pipeline where we believe there's long-term value creation potential. Looking forward, we expect our GNA expenses to remain relatively consistent for 2023 as compared to the fourth quarter of 2022. And we will focus our R&D spending on our top priorities, including advancing our ongoing comprehensive Phase 2 program for and Miracladines' Gets of Frenium. In the recently initiated Phase 1 trial of the Miracladines' healthy, elderly volunteers to support the development in Alzheimer's disease psychosis, initiating our Phase 2 trial for Derigabatin Pinnock Disorder.

Mark Bodenrader: In closing, we remain well capitalized with cash resources expected to fund our operations into 2025 that will allow us to achieve the next inflection point for each of our lead programs, including the seven mid-to-late stage data readouts we expect in 2024. I will now hand the call back over to Tony for closing remarks. Thanks, Mark, and thank you all for joining us to discuss our full year 2022 results. We're pleased with what we have accomplished so far and very proud of the work our team is doing in the pursuit of bringing much-needed medications to patients suffering from debilitating neuroscience diseases.

Speaker 2: and continuing the advancement of our other lead programs. In closing, we remain well-capitalized with cash resources expected to fund our operations into 2025 that will allow us to achieve the next inflection point for each of our lead programs, including the seven mid to late stage data readouts we expect in 2024. I will now hand the call back over to Tony for closing remarks. Thanks Mark and thank you all for joining us to discuss our full year 2022 results. We're pleased with what we've accomplished so far and very proud of the work our team is doing in the pursuit of bringing much needed medications to patients suffering from debilitating neuroscience diseases. Our top priority is maintaining the momentum in our emiraclating program and adults living with schizophrenia. We will continue to deploy the mitigation measures to offset the industry headwinds we and other companies are experiencing to advance the rest of our pipeline and expect to deliver set the seven data readouts that both Ray and I mentioned earlier.

Mark Bodenrader: Our top priority is maintaining the momentum in our Emrakratoc Program in adults living with schizophrenia. We will continue to deploy the mitigation measures to offset the industry headwinds we and other companies are experiencing to advance the rest of our pipeline and expect to deliver the seven data readouts that both Ray and I mentioned earlier in 2024. As always, we will be fiscally disciplined in focusing our spend on the highest-value programs, so I'll underscore Mark's point and maintain our cash runway into 2025, and we will remain open to new opportunities to maximize the value of our programs through creative dealmaking. We're looking forward to keeping you posted on our progress throughout the coming year. And with that, I will open the floor for questions. Operator.

Operator: Thank you. Ladies and gentlemen, to ask a question, you will need to press star 1-1 on your telephone and wait for your name to be announced. To withdraw your question, press star 1-1 again. Please stand by while we compile the Q&A list. And our first question, coming from the line of Michael Hewit-Jeffrey, Ceylon, is open.

Michael Yee: Hey, good morning, guys, thanks Tony for the update. We had a question.

Michael Yee: We had a question around the updates for the timing of Tabapidon, as well as the ongoing analysis around the potential new timing for Derigabat and epilepsy. As I was wondering, if you could just sort of re-cl clarify, are there things that are different going on for Tabapodon versus Derogabat? And what are the learnings or what are the improvements you're doing there as a read-through to encoding for schizophrenia, which you're saying will be in the first half of 24. And so I want to sort of test your confidence in your data for schizophrenia given the changes for the other two programs. I think that makes sense. Yeah, Mike, that's right.

Speaker 4: ongoing analysis around the potential new timing for Derrickabat and epilepsy. As you're wondering if you could just sort of reclareify are there things that are different going on for Tavapet on versus Derrickabat and what are the learnings or what are the improvements you're doing there as a read through to?

Speaker 2: and RACLID in first gets a frendia, which you're saying will be in first half 24. And so I want to sort of test your confidence towards your data for gets a frendia, given the changes for the other two programs. I think that makes sense. Thank you. Yeah, Mike, that's very clear. I'm going to ask our way to comment with some specificity. But let me make a couple of very quick points. One, we've said that the enrollment forum RACLID has proceeded well and doesn't need continue to proceed well. Some of this may be that it's an inpatient trial and it's a more controlled circumstance and setting. And some of these industry headwinds across the trials that we are seeing appear to generally occur more on the outpatient trial side of things. So that gives us certainly some confidence that the moment there's no change in our guidance or expectation for the RACLIDs gets a frendia program. And we are expecting those data in the first half of 2024. As to the rest of the trials and the industry headwinds that we're going to be doing, and observing there, there are certainly a number of macro environmental factors. We've talked about this sort of previous calls, staffing shortages at some of the sites, the ability to recruit new personnel to run the trials at these academic research centers and clinical trial sites. And a number of things there are a result of the displacement and the discontinuities in a.

Dr. Tony Coles: Yeah, Mike, that's very clear. I'm going to ask where to comment with some specificity, but let me make a couple of very quick points. One, we've said that the enrollment for Meracladeen has proceeded well and does indeed continue to proceed well. Some of this may be that it's an inpatient trial, and it's a more controlled circumstance and setting, and some of these industry headwinds across the trials that we are seeing appear to generally occur more in outpatient trials. side of things.

Dr. Tony Coles: So that gives us certainly some confidence that at the moment there's no change in our guidance or our expectation for the Amrakutin schizophrenia program, and we are expecting data for that in the first half of 2024. As to the rest of the trials and the industry headwinds that we're observing there, there are certainly a number of macro environmental factors. We've talked about this on previous calls, staffing shortages at some of the sites, the ability to recruit new personnel to run the trials at these academic research centers and clinical trial sites and a number of things that are a result of the displacement and the discontinuities in a post-COVID environment.

Dr. Tony Coles: We've done a pretty exhaustive review of clinicaltrials.gov just to get our arms around this particular dynamic and note that there are at least nearly a dozen companies experiencing six to 12-month delays in their clinical trials, likely affected by the same set of circumstances that we and others are encountering. So I offer that, Mike, just as context and landscape because I think the landscape is everything in really trying to understand your question.

Dr. Tony Coles: There are specific micro-environmental factors relevant to the Derigabat program and the Tabapidon program, enrollment, trial design, and Ray can speak to some of those things. But the bigger issue we expect is more broadly being experienced by a number of companies across the industry. But, Ray, why don't you provide some more specific comments on Tabapodon and Derigabat? I think I've dispensed with the Enraqadian question, because we are on track. But I will talk about those two studies in particular. Good morning, Michael.

Ramiro Sanchez: Good to hear from you. So for Tabapidon, we'll start with that first. As Tony mentioned, we've experienced the same challenges in the landscape that exists. The O-O-3, which is the adjunctive trial, will read out in mid-20204, and the monotherapy trials will read out in the second half of 2024 to that end. In order for us to rescue that timeline as much as possible, we're adding additional sites in the Asia-Pacific region, and those will be up and running later this year.

Speaker 3: will read in the second half of 2024 to that end in order for us to rescue that timeline as much as possible. We're adding additional sites in the age of the Pacific region and those will be up and running later this year. So we're encouraged by that, but we're committed to those timelines. In terms of Derrick about in the epilepsy program in the middle of last year, we implemented mitigation plans since we were impacted by the overall landscape, but also the concomitant medication challenges. However, as you know, it takes about six to nine months to implement these contingencies in another six months or so to see the enrollment impact. So in late January , we observed that these mitigations that we had implemented last year were not taking, we're not taking effect, it could not really offset the industry headwinds. And while there is good momentum currently, we're encouraged by that.

Ramiro Sanchez: So we're encouraged by that, but we're committed to those timelines. In terms of Derigabat and the epilepsy program, in the middle of last year, we implemented mitigation plans since we were impacted by the overall landscape, but also the concomitant of medication challenges. However, as you know, it takes about six to nine months.

Ramiro Sanchez: to implement these contingencies in another six months or so to see the enrollment impact. So in late January, we observed that these mitigations that we had implemented last year were not taking, we're not taking effect. It could not really offset the industry headwinds. And while there is good momentum currently, we're encouraged by that, we know we will not read out in 2023, as we mentioned earlier, and plan to update our new timelines for a data readout by most. mid-year.

Speaker 2: We know we will not read out in 2023, as we mentioned earlier, and plan to update our new timelines for a data readout by mid-year. Robert, before we take the next question, we're just, you always make this point for me and the rest of the team, and that is our intense focus on maintaining data quality. That's right. So one of the things, I just draw this to the attention of everyone, one of the things, a simple question could be, we'll just add more sites to actually rescue the timelines. And the risk in doing that is that you suffer in terms of the quality of the data and the quality of the enrollment of patients. And we saw this in a large farmer partners, large farmer companies announcement last week about some of the data quality issues that they had. So we don't want to repeat that. And I think our clear focus on data quality and maintaining data quality. So we deliver high quality information. The interviews trials is really important. So there's probably not more to add on that, but feel free to append that. I'm really compelled by that piece. That's right. And to Tony's point, we try to minimize the variability in all of our clinical trials, as you know, that ensuring the greatest likelihood of success is really the key objective. So unfortunately mitigation, when they're put in place, you're not doing it in real time. They take time to take effect, but you don't want to risk the trials. By any means, by adding too many sites. And so that's part of the challenge of really maintaining the...

Dr. Tony Coles: Operator, before we take the next question, Ray, I just want to make this point for me and the rest of the team, and that is our intense focus on maintaining data quality. That's right. So one of the things, and I just draw this to the attention of everyone, one of the things, a simple question could be, we'll just add more sites to actually rescue the timelines.

Dr. Tony Coles: And the risk in doing that is that you suffer in terms of the quality of the data and the quality of the enrollment of patients. And we saw this in a large pharma partners, large pharma companies, announcement last week about some of the data quality issues that they had.

Dr. Tony Coles: So we don't want to repeat that, and I think our clear focus on data quality and maintaining data quality so we deliver high-quality information at the end of these trials is really important. So there's probably not more to add to that, but feel free to append that. I'm really compelled by that piece.

Ramiro Sanchez: That's right. And to Tony's point, you know, we try to minimize variability in all of our clinical trials. As you know, ensuring the greatest likelihood of success is really the key objective. So unfortunately, mitigation, when it's put in place, you're not doing it in real time. They take time to take effect, but you don't want to risk the trials by any means by adding too many sites, and so that's part of the challenge of really maintaining the quality of the trial, but we understand also how important the timing of the readout is to try to get the medications sooner than later to the Operator. We'll take the next question.

Operator: Thank you. One, Mom's respond to the next question. And our next question coming from the lineup: Matthew Harrison with Mark and Stanley Yelanis Open.

Operator: Hi, this is Max Goron on behalf of Matthew Harrison. Thank you for taking our questions. But just following up on the previous comments, can you provide any additional thoughts on the potential risks from the COVID enrollment issues? Have you changed any key criteria to improve enrollment? And could that impact the placebo rates? And also, could you comment on the design and rationale for the panic disorder trial? Thank you very much. Great, why don't you take both?

Ramiro Sanchez: Yeah, so good morning. So, no, we have not changed any of the criteria in the trials. I think those trials were well designed, and, you know, we'll continue to focus on the quality of that data moving forward, so we have not amended any of those protocols. And the second question. Would you add a disorder study design? Yeah. So we are currently finalizing the trial design, and we will disclose that later this year, but it's on track, and we plan to initiate that program in the second quarter of this year. Okay, Max, thanks for your question. Operator, we'll take the next one.

Operator: Thank you. One moment for our next question. And our next question comes from the line of Paul and Seas with Stifle, Yolenessauvin. Thanks so much for taking my question.

Speaker 1: Okay, Max, thanks for your question. Operator will take the next one. Thank you, one more for our next question. And our next question coming from the line of palm and seeds with stifle, yell and a soap.

Operator: Thanks so much for taking my questions. I have one financial question and one clinical question. On the finance side, I was wondering if you could expound a little bit more on your cushion with cash into 2025. You know, in an ideal world, right?

Speaker 5: Thanks so much for taking my questions. I have one financial question and one clinical. On the finance side, I was wondering if you could found a little bit more on your cushion with cash into 2025. In an ideal world, right? You could finance on positive data, but now there's no more clinical catalyst this year. It would seem like waiting until the muscularinic readout would run the risk of getting to 12 months of cash, but maybe that math is wrong, so it would be helpful if you could expound there. And then on the clinical side, on the healthy elderly study, can you just lay out what a positive outcome in that trial looks like? It would seem like the adverse event rate.

Operator: finance on positive data, but now there's no more clinical catalyst this year, and it would seem like waiting until the muscarinic readout would run the risk of getting to 12 months of cash, but maybe that math is wrong, so it would be helpful if you could explain there. And then on the clinical side, in the healthy elderly study, can you just lay out what a positive outcome in that trial looks like?

Operator: It would seem like the adverse event rate is going to be higher than schizophrenia naturally. Where's the line on what's acceptable from a therapeutic index? And do you feel like you need to get to the same dose in ADP that you've been pursuing in schizophrenia? Thank you.

Speaker 2: is going to be higher than schizophrenia naturally. Where's the line on what's acceptable from a therapeutic index? And do you feel like you need to get to the same dose and ADP that you've been pursuing in schizophrenia? Thank you. Okay. Let me make a couple of general comments on the finance question and I'll ask Mark to comment specifically. One of the things that we do, Paul, is obviously, as you know, we make investments to get our trials to the next inflection point and that's true for everything that we've talked about today. The question is clearly into 2025 or what is it we'll be doing, but what are the things that we do is consistently sweep the budget for unused dollars that can be reinvested or put forward to additional expenditures in 2024. So we're doing all of this in real time on an ongoing basis and we'll continue to do that. To make sure that we can extend our cash one way for as long as possible. We're confident that the data we'd out that we've talked about earlier today will give us additional opportunities to create value in the pipeline, but Mark, what makes some specific comments about how we think about cash and cash management? Yeah, sure, Tony. You know, we do think about cash and cash management very carefully on a regular basis. And as Tony mentioned, is we're constantly evaluating our choices, but we always focus on maintaining.

Dr. Tony Coles: Okay, let me make a couple of general comments on the finance question, and I'll ask Mark to comment specifically. One of the things that we do, Paul, is, obviously, as you know, we make the investments to get our trials to the next inflection point, and that's true for everything that we've talked about today. The cushion is clearly into 2025 for what it is that we'll be doing, but one of the things that we do is consistently sweep the budget for unusually dollars that can be reinvested or put forward to additional expenditures in 2024.

Mark Bodenrader: So we're doing all of this in real time on an ongoing basis, and we'll continue to do that to make sure that we can extend our cash runway for as long as possible. We're confident that the data readouts that we talked about earlier today will give us additional opportunities to create value in the pipeline. But Mark, why don't you make some specific comments about how we think about cash and cash. Yeah, sure, Tony.

Mark Bodenrader: You know, we do think about cash and cash management very carefully on a regular basis. And, as Tony mentioned, we're constantly evaluating our choices, but we always focus on maintaining our cash runway, and we're focused on making sure that we can, you know, have the cash runway extended to 2025. But, you know, we're really happy with the strength of our ballot sheet. And, you know, our cash runway will support us through the seven days. readouts that we spoke of earlier. And that will, you know, we've done a pretty good job, you know, matching our runway with our financing cap. Good, Thank you.

Speaker 2: our cash runway and we're focused on making sure that we can, you know, have the cash runway extended to 2025, but, you know, we're really happy with the strength of our balance sheet. And, you know, our cash runway will support us through the seven data readouts that we spoke of earlier and that will, you know, we've done a pretty good job, you know, matching our runway with our financing cowlists. Good. Thank you. And John Rainer, would you mind talking about dosing in ADP? Sure. Thank you, Tony. And thanks for the question, Paul. So, yeah, so what we're looking for in the healthy elderly study, as, as you know, for any phase one study, we're looking for safety and tolerability in the age target population. And so in this case, as you know, we've characterized receptor occupancy by dose. As you know, we have data to support getting to 70% received. receptor occupancy or greater. Also, as you're aware of Paul, we've done a very careful analysis of correlating data of receptor occupancy with PK exposure and impact on the panscore from the earlier schizophrenia study. We do expect that we would probably need to be in the same range. However, as you know, the standard of care and treating the Alzheimer's population is on top of, you know, some, some type of a seat of calling esterase inhibitor. So, I think that, you know, the safety and tolerability will be relevant to the population ultimately. And so I have to characterize that as we go past the healthy, elderly study. But for us, it's really getting to that 70% receptor occupancy to validate that the dose is tolerated and safe in the elderly population and then moving.

John J. Renger: And John Ringer, would you mind talking about dosing in ADP? Sure, thank you, Tony, and thanks for the question, Paul. So, yeah, what we're looking for in the healthy elderly study, as you know, for any phase one study, we're looking for safety and tolerability in the age-target population. And so in this case, as you know, we've characterized receptor occupancy by dose. As you know, we have data to support getting to 70% receptor occupancy or greater.

John J. Renger: Also, as you're aware, Paul, we have done a very careful analysis of correlating data of receptor occupancy with PK exposure and impact on the PAN score from the earlier schizophrenia study. We do expect that we would probably need to be in the same range.

John J. Renger: However, as you know, the standard of care in treating the Alzheimer's population is on top of, you know, some type of acetylcholine esterase inhibitor. We do think that, you know, safety intolerability will be relevant to the population ultimately, and so we have to characterize that as we go past the healthy elderly study. But for us, it's really getting to that 70% receptor occupancy to validate that the dose is tolerated and safe in the elderly population, and then moving forward into the patient population with standard of care.

John J. Renger: And as you know, there's been some characterization that's been done by a peer company. It actually shows that when standard of care is added to a PAM, what you actually see is a benefit in the ability of the PAM to bind, because as you know, PAMs encourage binding of acetylcholine to acetylcholine esterase inhibitors, you can actually increase that binding. And so we believe that, you know, tapering from the healthy population into the patient population with standard of care, there actually can be a boost in the efficacy of a PAM at that point.

John J. Renger: And so we'll have to look at all the data, but we have a very good idea of what dose range and exposure we want to get to based on pet receptor occupancy, and we're thinking ahead around the standard of care interactions that will occur in the patients. I hope that it helps. And one's going to go to the population as well. Yeah, yeah. Yeah, so important. That was in my follow-up, actually. You're confident in QD for this population as well?

John J. Renger: Absolutely, yeah, so titration in the once-a-day dosing is going to be really important for this particular cognitively challenged population, as you know, because medication burden is a very serious concern in that population, and how you manage those meds will be important. And so having a once-a-day formulation will be really key here. Okay, operator, thank you, J.R. Thanks Paul for the question. Operator, we'll take the next one.

Operator: Thank you. Our next question, coming from the line of Jessica Fywood, Jayfew Morgan, Yelan, is open.

Operator: Great, good morning guys, thanks for taking my questions. Two for me, first, with phase two of Darygabat starting up in panic disorder, what specifically do you think that product needs to show in that trial to support a clinically competitive profile? And then second, on Mrakladine, when the Empower studies read out, what specifically are you going to be looking at to establish or define areas of differentiation from other approved or development stage drugs for schizophrenia? Thank you.

Speaker 6: First, with the Phase 2 for Derigabat starting up in panic disorder, what specifically do you think that product needs to show in that trial to support a chronically competitive profile? And then second, on emiraclidine, when the Empower Studies read out, what specifically are you going to be looking at?

Operator: Okay, thanks for the question. I'm going to actually ask Ray to comment on the endpoints that we are considering or how we're thinking about the design of that trial. And then I want to make a couple of marketing comments, Jess, on both of those questions. Go ahead. Jess, thanks for the question. Good morning to you.

Ramiro Sanchez: So we are currently finalizing a trial for panic disorder that just started in the second quarter of this year. As you know, there hasn't been a therapy approved for panic disorder since 2005, so it's been 18 years.

Ramiro Sanchez: But typically, what the FDA is looking for is really the reduction of panic attacks, usually in the last couple of weeks of the trial. These are trials that go on probably for 12 weeks in duration since it takes time for panic symptoms to actually decrease for a longer period of time. So that's the general premise, and we will disclose that trial design after we have had those interactions with the agency. But again, the plan is to start in the second quarter of this year.

Ramiro Sanchez: In terms of Rackladine, as you know, they are pretty standard trials in terms of what we're looking for. We're looking at the mean change from baseline on the PAN's total score. So we'll be looking at that change in the PAN's total score.

Ramiro Sanchez: We'll also be understanding the change in PANs also as a function of placebo. Those trials are 90% power, which shows at least a seven point placebo adjusted difference. So we'll be looking at that collectively.

Ramiro Sanchez: Of course, the tolerability profile is also important. So I think taking it in its totality, understanding the full dose range of 10 milligrams to 30 milligrams and understanding the efficacy profile there, as well as the tolerability profile, will collectively serve as the package that will be submitted to the agency for the approval of a bracketing treatment to treat schizophrenia.

Dr. Tony Coles: And then, on the second half of your question about each one of those in terms of competitive positioning, I'll just, I'll start by framing it as what I always call the central unifying thesis for Cerevel, which is this notion that targeted receptor selectivity matters. And in the case of Drigabat, if the data hold up, then we should be able to deliver efficacy both in panic disorder and in epilepsy while improving the tolerability profile with what's currently available. And that would largely be able to be.

Dr. Tony Coles: in the sense of avoiding withdrawal, dependence, et cetera, which are some of the common side effects observed with benzodiazepines. We think this is a big deal, and we think it matters, because right now, those side effects for benzodiazepines limit the prescribing potential for them to a shorter term duration rather than a longer term duration, which we think will benefit patients in the end. And similarly, for Imraklidin, we think selectivity matters in terms of avoiding some of the side effects that are currently being experienced by patients for in-market and development stage programs.

Dr. Tony Coles: but, as importantly, in this fragile population, once daily dosing and no need for titration, we think, will be distinguishing features that will make a difference to patients and providers. So I'll always draw us back to that central unifying thesis of targeted receptor selectivity because it is the reason to believe in Cerevell and in our program. Operator will take the next question.

Operator: Thank you. And our next question comes from the line of Humera-Futt with Evercarasa. Your line is open.

Operator: Good morning, guys. Thanks for taking my question. I have a couple here, if I may, on the Alzheimer's side of the program. Perhaps first, I was just curious. Theoretically, you could go right into Alzheimer's patients, and I'm trying to understand why do the ease trial first and when's the earliest we can actually expect data from the Alzheimer's side. Secondly, I know the focus is hallucinations and agitation in the Alzheimer's process.

Operator: program. There is some evidence, perhaps, even from the old Lilly trial on cognition. I'm

Operator: cognition, I'm curious how you're thinking about that endpoint, is that also? And then finally, there was a Merck M1 Selective, Positive Alestric Modulator, which wasn't successful in cognition, but they never really broke out data in hallucinations and agitation. I'm curious if there's anything you understand from that study that is also relevant. I think we'll ask John Ringer to attach answers to those questions and respond for us, J.R. Sure, thanks, Amur.

John J. Renger: Yeah, so first, why do we need to go into the healthy population first? And so it's a standard approach to actually show safety and tolerability in a healthy population before you go into a patient population, just because you don't want to find out in patients if there is a safety or tolerability issue, which obviously, at this point, with the number of patient exposures we have, we don't think it's a concern, but you always want to go into a healthy population and establish the safety So it's, it's, you know, industry standard practice to do that.

John J. Renger: And so, as you know, the phase one study that we announced is actually a multiple-sending dose study, and so we'll go through a number of cohorts, and we've talked about that dose range. And for those cohorts, they will be two weeks in duration, and after each cohort, we'll have a safety and tolerability review before we proceed. to the next dose escalation. We haven't announced when that data will come out, but, you know, it's not that far into the future that you should be hearing something back.

John J. Renger: JR, just before you go to the second response, we don't actually currently have data on the elderly, which is part of what we need to collect here. So I just emphasize that for everyone because schizophrenia is a little bit younger. So we've got to go collect this data in this older population. Yeah, thanks, Tony.

John J. Renger: Another question that you had was, and I believe, Omer, you mentioned collucinations and agitation. We're actually looking at hallucinations and looking at delusions, not agitation in that study. So an agitation study would be separate. So what we're looking at in the AD population, in particular for the study that we have planned, is looking at hallucinations and delusions that's separate from an agitation study, which would be a slightly different population. Yeah, and so the relevance of what we're doing with cognition there is that, you know, obviously, what we believe with the M4 mechanism is its great potential for showing safety and tolerability based on our schizophrenia experience.

John J. Renger: And what we know about the M4 receptors, this expression in the striatum is ideal for actually targeting the part of the brain that underlies hallucinations and delusions, and that's really what we're focused on. Obviously, you could see a benefit in cognition, but you would also have to address the pseudo-specificity of a potential increase in cognition that you might see once you address those issues. And so looking at cognition purely is a separate trial design.

John J. Renger: And so what you'd have to do is look in a stably treated population and then look for the cognitive benefit to really separate a cognitive benefit from the benefit that a patient might achieve from addressing the hallucinations and delusions. And so that would have to be a separate study design in a patient population where you've achieved this oppression of delusions and hallucinations or even a separate population away from that.

John J. Renger: So it's a little bit beyond what we've actually talked about doing right now at this point. And to your point about Merck and their compound, so as you know, I was at that particular company at the time those studies were going on. So that data is published, and it's publicly available. They were really focused on looking at two things, the ADS COG and looking at activities in Deal Living, which are the kind of standards in areas for improvement that the agency wants to review.

John J. Renger: There was not any release data at that point for looking at hallucinations and delusions. However, I would refer you to this anomaly data, which actually showed really good dose-dependent effects for addressing things like, you know, outbursts, paranoia, and hallucinations in that study. So it really gives a lot of confidence in the role for an M4 active compound and being able to address that aspect of this all-time-disease and, you know, really drives our excitement around the potential for bringing a highly selective M4 compound into a space where we know it works in psychosis and can address those particular issues in a patient population.

John J. Renger: And so we really believe that the M4 is really going to be able to address the hallucinations and delusions, and do the cognition piece, that would be a separate study design and a further approach in an appropriate patient population. Okay, thank you, JR. Operator, next question.

Operator: Thank you. And our next question coming from the lineup, Charles Duncan with Kenzer, Yulin is open.

Operator: Yes, good morning, Tony and team. Thanks for the update and thanks for taking our questions. I had two on the Rackladim.

Operator: programs. The first is with regard to Empower 1 and 2. You mentioned that enrollment was going well. Were you referring just specifically to patient numbers or, say, the geographic spread of enrolling sites or some other phenotypic measure? And then the second question is regarding Empower 3 in terms of the open label extension. Could you please provide a little more? color how that works. Do our patients take an off drug and then put it back on? And if not, can you give us a sense of the rollover rate for that and perhaps even persistence in power three?

Operator: Okay, Ray, why don't you take both of those for America? Sure. So good morning, Charles. So in terms of how they're progressing, that those trials are going well, so when we mentioned that earlier,

Ramiro Sanchez: and it's really the enrollment that we're seeing in both Empower 1 and in Power 2. In terms of the Open Label extension, Empower 3, as you know, Empowers 1 and 2 are blinded, so we don't know who's on the drug and who's on placebo. But what happens is if the participant wants to, they roll over into the open label extension, and then they start on the drug, and it's up to the investigator to determine what doses of therapy they can be on, and it lasts 52 weeks.

Ramiro Sanchez: And that will really serve for us to get the needed tolerability exposures, but when we file the NDA, at least 300 at six months and at least 100 at one year at target doses will be added as the total package for approval of the treatment of schizophrenia. And then the enrollment period,

Ramiro Sanchez: Thank you, one more for the next question. And our next question, coming from the lineup, is Mohit Banza with Wells Fargo Yalanisdav. Great.

Operator: Great, thank you very much for taking my question. And I just wanted to dwell more on the derogabed delay here. So I want to understand what exactly is going on. Are patients not getting diagnosed with epilepsy as much, or is it the enrollment issue, which is the slow-or? Or is it a follow-up issue? I wanted to ask, because you mentioned the outpatient setting. We'd also like to understand which trials you are looking at as well. Because, I mean, where we stand, we are looking at Alzheimer's trials going on and finishing on time. Lilly ran a head-to-head trial against Adilhelm, and Dick finished on time.

Speaker 2: also like to understand which trials you are looking at as well because I mean we where we stand we are looking at Alzheimer's trial going going on and finishing on time a time Lily Ranner had to had trial against against that you had to have them and they finished on time so it seems a little bit difficult to understand why this trial in particular getting delayed in outpatient setting what other trials you are looking at as well thank you so we don't thanks for the question we actually don't make a habit of commenting on other companies specifically but suffice to say I asked the team to pull the relevant Clint Riles dot-gov information and there are a number of other companies that are announcing six to twelve month delays across the landscape including in epilepsy as well and we won't mention specific names because that would be appropriate what we can say is that these larger industry headwinds are not peculiar or particular to cerebell or even to neuroscience they are occurring across therapeutic area and indeed we do have some specific considerations for the inclusion criteria for the Rigorbad trial which we are working through and one of the things that we expect to be addressing as we add additional sites so I think that as unfortunate as these headwinds are for all of us in the industry there are a number of really good examples what I can tell you is that when the team executes the execute very well witness the delivery of several important milestones in 2022 so when it's in our control we execute at the top of our game when it's outside of our control we work to put in mitigation plans and to address these issues as quickly and effectively as we can and that's what the team is doing. Operator let's take the next question.

Operator: So it seems a little bit difficult to understand why this trial in particular is getting delayed in the outpatient setting. What other trials are you looking at as well? Thank you. Thanks for the question. We actually don't make a habit of commenting on other companies specifically, but suffice to say, I asked the team to pull the relevant Clintrails.gov information, and there are a number of other companies that are announcing six to 12-month delays across the landscape, including in epilepsy as well. And we won't mention specific names, because that wouldn't be appropriate.

Dr. Tony Coles: What we can say is that these larger industry headwinds are not peculiar or particular to Cerevel or even to neuroscience; they're occurring across therapeutic areas. And indeed, we do have some specific considerations for the inclusion criteria for the Derigabat trial, which we are working through. And one of the things that we expect to be addressing as we add additional sites. So I think that as unfortunate as these headwinds are for all of us in the industry, there are a number of really good examples.

Dr. Tony Coles: What I can tell you is that when the team executes, they execute very well, witnessing the delivery of several important milestones in 2022. So when it's in our control, we execute at the top of our game. When it's outside of our control, we work to put in mitigation plans and address these issues as quickly and effectively as we can, and that's what the team is doing. Operator, let's take the next question.

Operator: Thank you. Our next question comes from the lineup, Douglas Sout, with H.C. Wenrich, Yulan is open.

Operator: Hi, good morning, thanks for taking questions. Just as a follow-up on the open-label extension for Enraquadine, and I'm just curious, do you have a sense of how that should affect timing or how quickly you'd be positioned to potentially file after completion of the phase two studies if they read out the way that we expect them to? Right?

Speaker 4: Thank you. Our next question coming from the line up, Douglas Selwich, HC Went Franklin on his open. Hi, I can want to ask you any questions. It's just as a follow-up on the open label extension for an wrackling and I'm curious to you at the sense of how that should affect timing or how quickly you'd be positioned.

Speaker 4: to potentially file after completion of the phase two studies if they read out the way they re-expect it well.

Ramiro Sanchez: So thank you for the question. So the Rackley and Open Label extension are both comprised of individual patients who actually roll over from Empowers 1 and 2, but we're also adding up to 40 de novo sites, and this is typically done to ensure that the open label extension is not on the critical path or rate-limiting to the submission of the NDA. So our hope is that by being able to have rollovers from Empowers 1 and 2 as well as the NOVA patients that are starting to enroll currently, we will be able to complete that trial in time for timely NDAs in Michigan. Okay, very good. Operator, I think we have time for just two more questions. So, what's next?

Speaker 3: Right? So thank you for the question. So we are, so the, the racially open label extension is both comprised of individual patients who actually roll over from Empowers 1 and 2. But we're also adding up to 40 denobled sites.

Speaker 7: And this is typically done to ensure that the open label extension is not on the critical path or rate limiting to the submission of the NDA. So our hope is that by being able to have role overs from Empowers 1 and 2 as well as in other patients,

Speaker 7: that are starting to enroll currently, that we will be able to complete that trial in time for timely NDA submission.

Speaker 2: Okay, very good. Operator, I think we have time for just two more questions. What's next?

Operator: Certainly. Our next question comes from the line of Greg Zavanevich from Musuha Group, Yelanis Elven.

Speaker 1: Finally, our next question coming from the line of Greg Sivan-Nefek from Mizuhau Garcia-H Greno, the L?halla Colonel-Hoolaroo, Pialina Stealthens.

Operator: Hey, thank you very much. Thanks for the update.

Operator: Tony had a question for you. It's a bit bigger picture. Certainly, you've got a nice cash balance that you're saying is taking you into 2025. And I'm just wondering that, you know, given what we've seen in the financing environment over the past 12 plus months or so. Has there been at any point in time a thought within the company to think about a further prioritization of programs or maybe a better deep prioritization of certain programs? Just want to know, given everything that you've got going on, whether that's been discussed internally and the reasons for or against it? Yeah.

Dr. Tony Coles: Yeah, Greg, thanks for the question. There are just a couple of things. One of the beauties of the way Cerevelle is set up and the way we have invested our dollars into our programs is that we have tried to fund the most important and the highest value return opportunities. One thing we do know is that we can't do everything. And we are making very specific and hard decisions about how we prioritize not just the mid-to-laborate.

Dr. Tony Coles: stage programs, but also the early stage programs as well, and do a really artful job of creating an artful balance between those highest value-returning programs that will deliver value to patients and shareholders in the near term and our investments for the long term. And that's just the art of good biotech executive management. So we do that on a consistent basis, but we should also, as I do, think about the ends as well as the outs.

Dr. Tony Coles: And we've talked about the fact that we are open to a variety of interesting and potentially fit far, um, uh, uh, financial arrangements. We've got a track record of doing interesting transactions like the risk-sharing arrangement that we have for Tabapidon with Bain and NovaQuest, and we're open to those kinds of ideas as well as partners. So I think you have to look at the composite perspective of how we think about capitalizing the business, how we form that capital on a non-equity dilutive basis, potentially, and how we think about prioritizing our programs.

Dr. Tony Coles: We do have a robust portfolio prioritization process that we review twice a year that allows us to deploy our dollars in the most effective way. So I appreciate the question, and you've got your finger right on the art of being a great CEO and a biotech company. Next question, offer.

Operator: Thank you. Now, the last question is coming from the line of Madhu Kumar with Goldman Sachs: Yelan is open.

Operator: It is Amari-on from Madu. We have a couple questions. First, how should we be thinking about the trial for erection in elderly patients in terms of safety, P-K, and PD? And then second, how should we think about the catalyst path for the company in the near future. J.R., do you want to take the ADP question? Yeah, thanks for the question.

John J. Renger: So I think the way to think about the ongoing study is that we've established previously the receptor occupancy using PET in the younger schizophrenia population. What we know is that there's been a recent publication by Lee-E-Dahl that examined the M-4 compound that they used in that paper to look at the conservation of M-4 and muscular activity in Alzheimer's disease patients. They established that while there was some decrease, largely, there was a retention of M-4 expression.

John J. Renger: and they also demonstrated through the use of acetylcholine esterase inhibitors that those enforced or atal receptors are not only present, but they're still functioning. And so we think that that's very educational because what it suggests is that the target is still there, it's still functioning, and that it can be potentiated both with an M4 selected molecule and the standard of care. And so this healthy elderly study that we're looking at is really looking at two weeks of safety and tolerability to establish the baseline dose range that we want to take forward.

John J. Renger: Once we've confirmed that, we'll be going into patients. And so I think really what you're looking at here is us examining the dose range that we think is appropriate to carry forward in the population showing safety and tolerability in patients up to 85 years old that will allow us to progress into the appropriate age group with the AD indication. And we should be looking at is, you know, the once-a-day non-titration approach that we have is really important, again, in this population that we want to intend to study. That, you know, having a once-a-day formulation is going to be really important as far as medication management is concerned, as I mentioned earlier.

John J. Renger: And so really, this one is really to inform our next steps, the dose range, looking at, you know, achieving their appropriate receptor occupancy with safety and tolerability to support that, and really, you know, helping us establish how we're going to move forward as we plan the next studies. And as to Catalyst, we've talked a lot about the seven mid-to-late stage data readouts we have in 2024. That's two for Imrakhalene, which is expected in the first half of next year. We will update further on Derrigabat, obviously. Tabapidon, the three studies comprised in the Phase 3 program, and then 871, which we expect data for next year as well.

Dr. Tony Coles: So we've got a lot to work on, a lot to focus on, and we'll be looking forward to bringing you all the updates that we need to. I think, operator, that's about time. I want to thank everyone for joining us this morning, and we will be in touch with additional developments as they arise. We look forward to chatting with you again in the next quarter. Thank you.

Operator: Please thank you, gentlemen, for joining us at the Duffengar Conference for today. Thank you for your participation. You may now disconnect. The conference will begin shortly. To raise and lower your hand during Q&A, you can dial star 1-1.
