Speaker 4: Thank you, Chris. Good morning. I appreciate everyone taking the time to join us today.
Speaker 4: We provided several important business updates this morning in our press release in 10K, including additional color on the FTX6058 full clinical hold, data from the now suspended 12 mg cohort of the Phase 1b sickle cell disease trial.
Speaker 4: updated guidance on our cache runway, and changes to our management team.
Speaker 4: Let me start by discussing our most recent updates to the FTX6058 program, our oral HPF inducer for the potential treatment of patients with sickle cell disease.
Speaker 4: As we announced on February 24th, we received verbal notification from the FDA on February 23rd that they had placed a full clinical hold on the investigational new drug application for FDX6058 and we received a formal clinical hold letter from the FDA on February 24th.
Speaker 4: We immediately suspended dosing and paused enrollment in the Phase 1b trial.
Speaker 4: In its communication to us, the agency noted that the hold related to both preclinical data previously submitted in April , October , and December 2022, and nonclinical and clinical evidence of hematological malignancies in the United States.
Speaker 4: observed as other inhibitors of the polycoma-presto-complex 2, or PRC2. The agency specifically noted that the profile of hematologic malignancies observed in the non-clinical studies of FTX6058 is similar to that observed with other inhibitors of PRC2, and that hematologic malignancies have been reported clinically with other PRC2.
Speaker 4: Prior to the clinical hold, we had completed dosing at 6 milligram dose and we're completing dosing patients in the 2 milligram cohort and we're enrolling in dosing the 12 milligram dose cohort.
Speaker 4: In early January , we shared data from the completed 6 milligram cohort with 10 patients that demonstrated up to 9.5% absolute HBF increases from baseline.
Speaker 4: and similar treatment responses to FDX6058 in subjects on and off background hydroxyurea.
Speaker 4: We also shared partial data from the ongoing 2 milligram cohort in January . This morning we provided an updated data set from the two patients that completed dosing in the 2 milligram cohort and the now suspended 12 milligram cohort in which we enrolled three patients.
Speaker 4: The two milligram patients that completed 84 days of dosing achieved absolute HVF increases up to 4.6%.
Speaker 4: Through the end of treatment, suggesting 2 milligrams is a potentially minimally efficacious dose.
Speaker 4: Data from a patient in our 12 milligram cohort who completed 42 days of treatment demonstrated absolute HPF increases up to 10% as well as improved biomarkers of hemolysis.
Speaker 4: A wave comparison at this same early time point of 42 days, adherent patients at the six milligram dose had an average increase in absolute HVF of four and a half percent, while adherent patients at the two milligram dose had an average increase in absolute HVF of less than one percent. So these new data continue to support a significant reduction in...
Speaker 4: of HVAC as well as a robust dose response effect.
Speaker 4: All three subjects with the 12 milligram dose also had an increase in hemoglobin of at least one gram per deciliter at the 28 day study time point.
Speaker 4: with one subject.
Speaker 4: achieving a 2 gram per deciliter increase by day 42.
Speaker 4: We find these initial data to be highly encouraging and further supportive of the clinical potential of this drug.
Speaker 4: FTX6058 has generally been well tolerated to date with no drug-related treatment emergent adverse events or discontinuations due to treatment emergent adverse events.
Speaker 4: All adherent subjects showed clinically relevant improvement in the 6 and 12 milligram dose cohorts, consistent across subjects both on and off background hydroxyurea, which is the current standard of care.
Speaker 4: These clinical data gave us great confidence that FTX6058 has the potential to provide a differentiated therapeutic option for people living with sickle cell disease and a favorable benefit-risk profile. We remain committed to 6058's further development and look forward to working closely with the FDA to address all outstanding concerns as rapidly as possible.
Speaker 4: We will provide an update once we have more clarity on the path forward.
Speaker 4: For now, we are suspending our previous guidance to complete the Phase 1b trial and our guidance to select a registration enabling dose in the fourth quarter of 2023.
Speaker 4: Now turning to our most advanced program, Losmapimod, a selective P38 alpha beta mitogen activated protein kinase inhibitor. Losmapimod is in phase 3 development for the treatment of FSHD. FSHD is an autosomal dominant genetic form of muscular dystrophy.
Speaker 4: which has an estimated patient population of 16,000 to 38,000 in the United States alone.
Speaker 4: It is characterized by progressive muscle death and fat infiltration and results in the inability to perform daily life activities due to a significant impairment of upper extremity function, loss of mobility, and chronic pain.
Speaker 4: While it is one of the most common forms of muscular dystrophy, there are currently no approved treatments, and we believe Los Mavimod has the potential to address the urgent need for a safe and effective disease-modifying treatment that can slow or stop disease progression. We initiated REACH, our double-blind placebo-controlled phase 3 trial of Los Mavimod, in June 2022.
Speaker 4: and are currently enrolling patients in the U.S., Canada, and Europe .
Speaker 4: The trial is expected to enroll approximately 230 adults and we are on track to complete enrollment in the second half of 2023.
Speaker 4: The primary endpoint is the absolute change from baseline in reachable workspace or RWS, a quantitative measure of upper extremity range of motion and function that specifically evaluates shoulder and proximal arm mobility with 3D motion sensor technology. Preserving a separate extremity function is critical for maintaining the ability for self-care, and for the safety and safety of the individual.
Speaker 4: and other activities of daily living that directly influence quality of life and independence.
Speaker 4: In addition to safety and tolerability, secondary endpoints include muscle fat infiltration, or MFI, an important marker of disease pathology, and self-reported outcomes, such as the patient global expression of change, or PDIC, in quality of life measures.
Speaker 4: These will include healthcare utilization questionnaires that will inform our thinking about payer strategy as we prepare for a potential commercial launch.
Speaker 4: REACH was designed as a highly efficient 48-week trial and is intended to be registration enabling, both in the U.S. and in ex-U.S. geographies.
Speaker 4: We are confident that we have selected reliable measures of disease progression, and we hope to demonstrate meaningful advantages for los naphmans compared to placebo.
Speaker 4: Encouraging our phase 2b redux 4 trial demonstrated significant improvement in RWS relative to placebo at 48 weeks.
Speaker 4: Furthermore, top-line results from the ongoing open-label extension show that participants in the initial treatment arm who continued to receive Los Mapimans demonstrated durability of effect through a 96-week period.
Speaker 4: Additionally, patients who crossed over from placebo to Los Mapimos after the initial 48-week trial period showed improvement in slowing of disease progression as measured by RWS mean change from baseline.
Speaker 4: We believe these data support the disease modifying potential and long-term benefit plus math and math.
Speaker 4: To date, Los Mapimat has been dosed in over 3,600 patients across multiple therapeutic areas and results from Redux4 and our open label extension trial provide evidence of an encouraging safety and tolerability profile.
Speaker 4: We have reached alignment as regulators in the U.S. and Europe on the primary end point for REACH, and as we drive our clinical path forward for Los Matenades, we'll continue to leverage the large safety database and build on our learnings from REDUX4, an ongoing open label extension trial.
Speaker 4: Now turning to other corporate matters, we announced this morning that Dr. Santiago Arroyo, our chief medical officer who joined us in November 2022, resigned from the company late last week, effective March 7th, to pursue another opportunity. We are excited to appoint Dr. Ian Frazier as interim CMO effective today.
Speaker 4: Dr. Crazier brings over two decades of experience in advancing therapies through early and late stage development and possesses deep expertise in regulatory affairs.
Speaker 4: He most recently served as vice president and clinical fellow at Aloe Vera, an Elevate Bio company.
Speaker 4: He previously held clinical development roles increasing responsibility at Abide Therapeutics that was acquired by Lundbeck in 2019 and prior to that was part of the clinical development organization at Merck.
Speaker 4: In addition to Dr. Praiser joining us, Dr. Alan Ezekiel, member of the Fulcrum Board of Directors since February 2017, will serve as a senior clinical advisor to ensure program continuity.
Speaker 4: With that, I will turn the call over to Esther to provide an update on our financial.
Speaker 4: With that, I will turn the call over to Esther to provide an update on our financials. Thank you, Robert.
Speaker 5: I will first provide an update on our cash position and runway guidance, and then review fourth quarter and full year 2022 financial results. We ended December 31, 2022 with cash, cash equivalents, and marketable securities of $202.9 million.
Speaker 5: compared to $218.2 million in December 31, 2021. In January 2023, we strengthened our balance sheet and cash positions following an underwritten public offering of 9.6 million shares of common stock at a public offering price of $13 per share.
Speaker 5: The gross proceeds from this offering were approximately $125 million before the deduction of underwriting discounts.
Speaker 5: and other offering related expenses and resulted in approximate net proceeds of $117 million to the company.
Speaker 5: We continue to operate from a strong financial position with a pro forma cash balance of approximately $320 million and expect our cash, cash equivalents, and marketable securities to fund our operating expenses into mid-2025, assuming a timely resolution of the FTX6050 clinical home.
Speaker 5: million for the fourth quarter of 21 and 19.2 million for full year 21. The decrease is primarily due to the previously announced termination of Fulcrum's collaboration agreement with Excelloron-Forma.
Speaker 5: Total operating expenses were $28.7 million for the fourth quarter of 2022 and $118.9 million for the full year 2022 compared to $28.6 million for the fourth quarter of 2021 and $100.2 million for full year 2021.
Speaker 5: The increase is primarily due to increased employee-related costs, including increased staff-based compensation, and increases in R&D.
Speaker 5: including a 5 million milestone paid to GSK upon the initiation of the Phase III REACH trial.
Speaker 5: Net loss was $26.1 million for the fourth quarter of 2022 and $109.9 million for full year 2022, compared to a net loss of $23.5 million for the fourth quarter of 2021 and $80.8 million for full year 2021.
Speaker 5: With that, I'll turn the call back to Robert for closing remarks.
Speaker 5: With that, I'll turn the call back to Robert for closing remarks. Thank you, Esther.
Speaker 4: We remain focused on driving our clinical programs forward, exploring opportunities to leverage the value of our research engine and executing on our corporate objectives.
Speaker 4: We remain on track to complete enrollment for our FSHD Phase III Reached Trial in the second half this year and are committed to working with the FDA to resolve the clinical hold on FTX 6050A.
Speaker 4: We will provide updates as communication with the FDA proceeds.
Speaker 4: I want to reiterate that we are optimistic there is a path forward to resolve the full clinical hold on FTX6058, and we are working diligently to enable FTX6058's expeditious return to the clinic.
Speaker 4: Before we conclude today's call, I want to extend my sincere appreciation and gratitude for the foundational work that has brought us closer to treating the root cause of genetically defined rare diseases and bringing transformative therapies to patients.
Speaker 4: I would like to thank the entire Polkum team, our investors, and the many people who have been supportive along the way, including our patients and their families. With that, we are happy to take questions.
Speaker 4: I would like to thank the entire Polkum team, our investors, and the many people who have been supportive along the way, including our patients and their families. With that, we are happy to take questions. Operator.
Speaker 2: We will now be conducting a question and answer session.
Speaker 2: If you'd like to ask a question, please press star one on your telephone keypad. The confirmation tone will indicate your line is in the question queue. You may press star two if you'd like to remove your question from the queue. You may press star two if you'd like to remove your question from the queue.
Speaker 2: For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys.
Speaker 2: For participants using speaker equipment, it may be necessary to pick up your handsid before pressing the star keys. One moment please while we pose for questions.
Speaker 2: We take our first question from the line of Matthew Harrison with Morgan Stanley . It's quite heavy.
Speaker 6: Great. Good morning. Thanks for taking the question. I guess two for me. So first, are you expecting to request the Type A meeting with the FDA? And could you maybe just talk a little bit about what your current plan is, given that you now have the full letter around handling the clinical hold? And then secondly, I'm going to ask you to please
Speaker 6: I guess just specifically on the hematologic malignancies that you observed in the rat study.
Speaker 6: Do you expect that you could potentially exclude certain patients from the clinical study to change the risk? Or do you think, and I know it's very early, do you think a new toxicology study may be necessary? Try not to get your heart rate in time.
Speaker 4: Thank you, Matt. Just taking your second question first.
Speaker 4: Thank you, Matt. Just taking your second question first.
Speaker 4: As we move forward in our dialogue with the FDA, they noted that they were really encouraging us.
Speaker 4: asking us to define a patient population that may benefit.
Speaker 4: us to define a patient population that may benefit from the
Speaker 4: that may benefit from the elevations in HPF and then therefore address the benefit-risk ratio. As you probably know, numerous other studies that have gone on in the sickle cell arena have defined higher risk, patients that are higher risk for things like VOC.
Speaker 4: And we're taking a close look at those studies. Our study was essentially an all comer study in sickle cell patients. And moving forward, one of the things we're considering is what a higher risk population, sickle cell population, would look like.
Speaker 4: The clinical hold noted that the profile of malignancies observed in the study of 6058 was similar to that observed with other inhibitors of PRC2, and we believe that we can address all other questions with the data that we have in hand.
Speaker 6: Thanks, Robert. Just a follow-up, are you planning to request a Type A meeting or not? I don't know if you know that yet.
Speaker 4: Yeah, we're still working through exactly what our strategy is going to be moving forward. Sorry, Matt. I meant to mention that. Certainly we've had the letter.
Speaker 4: almost immediately after we had the call with them, which really gives us a jumpstart on putting that plan together. And we'll keep updating as the plan develops.
Speaker 6: Great, thank you very much.
Speaker 2: Thank you. We'll take our next question from the line up Matt Bigler with OpenIMR. Please go ahead.
Speaker 6: Oh hey guys thanks for the question. What's the best comp here as it relates to cancer risk? Is it
Speaker 6: To Zemastat, that's an EVH1 inhibitor, but it also works on the PRC2 access. It was recently approved in, I think, lymphoma. Is there a reason to think the cancer risk might be lower with your drug? Because I think you're only reducing methylation by about 70%, whereas I think Zemastat completely ablates it. So, I'm just kind of curious what your thoughts are there.
Speaker 4: Yeah, that's precisely correct. So, tasimetostats improved in epithelial sarcoma as well as relapse refractory follicular lymphoma and that's therefore from the information that's been provided on tasimetostats, we have the most insight into what happens when you fully inhibit the PRC2 complex.
Speaker 4: In the label for Tasmatostat, they noted neutropenia, thrombocytopenia, anemia as reasons for dose modification of Tasmatostat. And I'd point out that in our healthy volunteer and our sickle cell population, we've not observed any of those effects. So we think there's...
Speaker 4: a fundamental difference in the clinic in how EED6058 is interacting and affecting hematologic development versus how an EZH2 inhibitor like Tazimatostat is affecting that.
Speaker 6: Does that answer your question? Yeah, that makes sense. I wanted to follow up on the prior question about identifying a patient population with maybe the ops and lawyers to benefit. Do you foresee something like including only patients with higher baseline HBF? And just remind us, has there been a link between baseline HBF and HBF induction?
Speaker 4: of HPF that we're seeing with FTX6058. That is, we now have patients whose baselines range from about 4% HPF to about 20% HPF.
Speaker 4: And certainly in six milligram data where we have the most patient experience, independent of where they start and independent of whether they are on hydroxyurea or not, we see similar increases of about 10% HPF.
Speaker 4: Alan, maybe you want to speak to the higher-risk population question. Yes. The Allcomers study that we did, which was an open-label study in Phase 1B, we recognized that we need incidents because we need a baseline of BOC and guided by some of our
Speaker 4: the studies that have been done with gene therapy and gene manipulation therapies, increasing the frequency of VOCs as well as the seriousness of other complications like your chest syndrome and other episodes are...
Speaker 7: parts of the population that we would like to exclude, and the strategy would be just like that. We would start with a high-risk population and then expand that out as we go along.
Speaker 8: Okay, that makes sense, thanks for the question.
Speaker 2: We take the next question from the line of Madhu Kumar with Goldman Sachs. Please go ahead. Hi, guys. This is Rob on from Ado. Thanks for taking our question. First, how does the PRC2 complex inhibition you observed compared to other PRC2 drugs used in cancer? And then what dose of...
Speaker 2: Do you pre-clinically observe hematologic malignancy risk? And what does that translate to clinically?
Speaker 4: Yeah, so we're, as we've discussed previously, we're getting about 70 to 80% inhibition of the H3K27 trimethylation.
Speaker 4: Mark, Tasmata staff where we have most insight into a PRC2 inhibition is getting 80 to 100 percent and and that
Speaker 4: appears to be the best differentiation that we can compare. We've not really discussed the degree of preclinical exposure related to the malignancies related to the clinical dose that we're using, but we're confident that we have the ability to define.
Speaker 9: with Credit Suisse, please go ahead.
Speaker 10: Yeah, hi, thanks for taking the question. Just following up on defining that benefit risk profile, have you had further clarity from FDA on whether potentially gene editing programs are precedent for definition of that risk or are they more leaving it up to you and is that what you're particularly working on?
Speaker 4: risk associated with them that they are discussing with the FDA. We think that provides...
Speaker 4: clarity on how we can define a population in which the benefit is greater.
Speaker 10: Okay. And is your sense that defining that population would be potentially a
Speaker 10: step into getting back to the broader sickle cell population or that you could be restricted to that.
Speaker 4: defined high-risk population? It's a little early for us to know that yet, because of course that involves discussions with the FDA. Our current plan is to define and discuss with the FDA what we think that higher-risk population is.
Speaker 4: And as Alan said, once we demonstrate a beneficial, what we think will demonstrate a beneficial benefit-risk ratio in that higher risk population, it provides the opportunity for us to continue discussions on additional populations.
Speaker 10: Okay, thank you. And then just left. We just curious, you know, we've seen some gene editing programs kind of kind of drop out in sickle, so I'll recently coincidental timing in your view, because there will be anything, you know, that maybe FDA communicated to those programs that might be related to your, and then maybe just more.
Kind of general on that needing sickle cell from FDA's perspective, do you have any incremental insight on that, which seems still to be pretty large, but understandably, risk benefit needs to be defined? Yeah, I think unfortunately for sickle cell patients, it's coincidental that all this data came up at the same time.
There is no indication in our correspondence that we received in the clinical hold letter that there was any read-through from the gene-editing world.
Thanks.
Thank you. Weíll take the next question from the line up dig in with Steve. Please go ahead.
Hey, good morning. Thanks for taking the questions. I'll stick with the nonclinical observations, if I may. Can you go into a little bit more detail around what exactly were the observations and the duration at which point you observed this? There were a couple of, I guess, references earlier about Tazimidostat, but that, I guess, label indicated about nine months before they saw that.
So when in your rat and potentially dogs, I believe the in-life portion is complete. Have you seen that? And then related to that going forward, I guess as you contemplate more non-clinical studies, what do you define as a bar for disclosure or materiality to disclose to the public? Thanks. As I like to call this, we Wheel Sarah Lovett Immigration Yes, they were Cup of
rat and potentially dogs, I believe the in-life portion is complete. Have you seen that? And then related to that going forward, I guess as you contemplate more non-clinical studies, what do you define as a bar for disclosure or materiality to disclose to the public? Thanks. Thanks, Daeung. Thanks, Daeung.
So just to remind you, we had done four 13, 17, and 26 week studies in rats, and four weeks, 13 weeks, and 39 week studies in dogs. We just received a draft report on the 39 week study in the dogs.
And certainly...
Much of that material was available to the FDA at the initial IND as well as provided.
and the updates that I referred to earlier in the script. We've not disclosed when, during the course of those treatments, the malignancies appeared, but certainly the FDA was comfortable with the...
healthy volunteer study as well as the initial sickle cell population.
We'll continue to provide updates as we have correspondence and dialogue with the FDA on how we define that benefit risk and particularly the plans and discussions with not only increasing the benefit side but also what they would and we would like to do to address the risk side. Hello I am with the State of California Business Association. Ugements durable and healthy forget about and how we'll serve them with Marcus recording what he did on theombric.com. If you have questions or concerns, please raise your hand00
Dagan, do you have any further questions?
further questions? No, thank you very much.
Thank you. We take an next question from the line up, Ted Tantov, with Piper Sandler, please go ahead.
Great, thank you very much. So I think we've extensively covered 6058. So you know, just good luck on that. And I think it's important.
you know, this drug could really differentiate with the broadest population possible, I think, if you're able to ultimately establish safety of that population. So I'm looking forward to hearing more as this progresses. So looking at this map, maybe just kind of remind us where you.
see this drug most appropriate? Is this a drug that would be broadly applied to, or again, I know we're working with Reachable Workspace as the primary endpoint, but what do you kind of see as the most appropriate patients of SHD for that drug? Thanks guys.
Thanks Ted. Yeah, we do think this is a drug that has potential to be broadly applicable in the FSHD population. I remind you that the population based on a white paper is a voice of the patient.
has repeatedly advocated for an agent that stabilizes the disease at the stage that they're at. It's a disease of adaptation and certainly with the reachable workspace results that we saw in the Redox4 study, we were able to stabilize patients where they were.
and patients that were on placebo declined and then stabilized when they crossed over to the open-label extension. That trial took patients who were in, if you will, a broad patient population who were showing symptomology but were not yet in a wheelchair, so in sort of 2 to 4.
range of the clinical scale that's used in FSHD. And that's where the bulk of the population lies. So we think it's probably applicable across a very broad patient population.
Great. Thank you. Excited for that data, you know, complete enrollment this year and that data hopefully next year. Thanks so much.
complete enrollment this year and that data hopefully next year. Thanks so much.
Thank you. We take the next question from the line of Joseph Schwartz with SVB Securities. Please go ahead. Hi. Thank you. I was wondering have you looked at the impact of FDX6058 on erythroid maturation via flow cytometry on CD34 cultures, and how do you see the impact of FDX6058 on erythroid maturation?
to determine that it isn't inducing maturation arrest. And a related question, have you done any red blood cell viscosity, deformity, morphology in NLCs on the patients treated so far? And what about F-cell data in order to be confident that FTX is promoting the development of quality RBCs?
Yeah, we have looked at the red cell differentiation of metapoiesis and really don't see any effect and that's consistent with the correction of anemia that we're seeing.
in the patient population. Certainly we didn't see any effect on erythroid maturation in
in vitro or in vivo studies.
One potential data that you might focus on is the reduction in the absolute reticulocyte count, but that's consistent with ameliorating the anemia, and there's no other evidence or an effect on the red cell differentiation. In terms of deformability of the red cell, what we've looked at…
is the RDW, the distribution width, which is sort of a surrogate for deformability. And as we showed at 6 and also as we're seeing at 12, we get normalization of those parameters.
So that's consistent with preventing the sickling event from occurring. We're still analyzing the percent F cells. I'll remind you in the pre-clinical studies we saw all of the cells responding that is
The percent of cells were pancellular, or the raise in HPF was pancellular.
Okay, thanks. And then will you be reporting any more data on the...
particularly those involved in......an off drug now.
Yeah, as we move forward and as...
We provided all the data we have as of I forget the exact cutoff date, but we've provided all the data we have
in hand currently and we'll be considering how we provide updates on these patients moving forward. But certainly we're still interested and we're still following them.
Thank you. Thank you. We'll take the next question from the line up to Zeen Ahmed with Bank of America. Please go ahead.
Hi, good morning, and thank you for taking my questions. Robert, just to clarify maybe on timelines, if we could, do you think that if you're correct in that you think you'll be able to answer all the questions the agency has with data that's in-house, do you think that the critical hold...
could be listed in this calendar year or could it be something that could take a while? And then secondly, can you remind us of what next gen assets you have in-house, how you quantified them so far and what their profile might be in terms of differentiating on the safety side? Thank you.
listed in this calendar year or could it be something that could take a while? And then secondly, can you remind us of what Next Gen assets you have in-house, how you quantified them so far and what their profile might be in terms of differentiating on the safety side? Thank you. Yeah, so.
We've not, as we're still engaging in dialogue with the FDA, it's a little hard for me to predict how quickly the clinical hold will be lifted because, as you know, there's timing that we don't control. We're anticipating it will be at least four to six months.
at the earliest. We have a number of other programs that in both the sickle cell as well as the muscular dystrophy states it at the preclinical drug discovery stage and we'll be discussing those more in the future.
You probably recall, we do not anticipate filing another IND this year. Would the feedback from the FDA change that plan at all?
No.
Okay, thank you. Thank you. Ladies and gentlemen, we have reached the end of the question and answer session. And I would now like to turn the floor back over to Robert Gould for closing comments. Over to you, sir. Well, thank you. Thank you very much to everyone for your time and attention.
