Speaker 2: On today's call, we have George Lovesgate, our Chief Executive Officer, and Charlie Degnan, our Chief Financial Officer. After our formal remarks, we will open the call for your questions. I would now like to turn the call over to George.
Speaker 3: Thank you, Jenny. We delivered a productive start to 2023 as we execute on our near-term plan to advance our lead asset, CLSAX, an investigational proprietary suspension of Exidinib for supercory loan injection. Exidinib is a highly potent, piracy in kinesine inhibitor.
Speaker 3: that achieves pan-VEGF blockage, directly inhibiting VEGF receptors 1, 2, and 3, with high potency and specificity.
Speaker 3: We believe this broad VEGF blockade may have advantages over existing therapies for retinal diseases by acting at a different level of the angiogenesis cascade.
Speaker 3: Supercaroidal injection of our proprietary CLSAX suspension delivers Xidinib directly to the site of disease and has demonstrated signs of biological effect and the potential for extended duration of therapy in our Phase 1-2a OASIS clinical trial in wet AMD.
Speaker 3: Results from the Oasis trial and Extension study were presented last month at the Arvo Annual Meeting by Dr. Dennis Marcus.
Speaker 3: The trial consisted of four cohorts with single escalating doses of CLSAX administered to participants who were then followed for three months.
Speaker 3: All participants enrolled in Oasis were heavily anti-vegetal treatment experienced with active disease at screening, which was confirmed by an independent reading center.
Speaker 3: This three-month trial was followed by an additional three-month extension study in the higher dose cohorts for a total of six months follow-up for those OASIS participants who elected to continue.
Speaker 3: CLSA X was administered by our proprietary SCS micro-injector, demonstrated an excellent safety and tolerability profile at all doses and in all cohorts.
Speaker 3: There were no adverse effects, no dose limiting toxicities, no sign of inflammation, and because we inject behind the retina, we didn't have any instances of detrius floaters or dispersion of drugs into the vitrius.
Speaker 3: We anticipated this favorable safety profile as exidant of as a well-characterized small molecule with much less propensity for ocular inflammation as compared to the administration of biological agents or viral-based gene therapy.
Speaker 3: In terms of outcomes, the OASIS Extension Study demonstrated that two-thirds of wet AMD patients in the two higher dose cohorts were able to go at least six months without additional treatment. Participants experienced a 77 to 85 percent reduction in treatment burden. As measured by the number of anti-VEGF treatments they received during the six months, the number of patients who received the OASIS was
Speaker 3: Compared to the six-month period prior to entering the OASIS trial.
Speaker 3: Also, we observed anatomic signs of biological effect and reported stable mean best corrected visual locuity or BCVA and stable mean central sub-guilt thickness or CST in the extension study participants in the two higher-dosed cohorts. These promising results are supportive of the potential safety potent.
Speaker 3: randomized double-mass, multi-centered Phase IIB clinical trial in participants with WET-AMD.
Speaker 3: Our primary goals for Odyssey are to demonstrate improved duration and reduce treatment burden for the CLSA X arm while maintaining visual acuity.
Speaker 3: We expect that the results of this trial will provide the necessary data to properly inform the design of phase 3 program for CLSAX in wet AMD.
Speaker 3: We believe CLSAX has the potential to be a twice a year maintenance drug for LED AMD, which, if demonstrated, would compare favorably to unlabeled maintenance dosing for the currently approved anti-begette drugs. The centrist unlabeled is 12 times a year, I leot 2 milligrams is 6 times a year, and the bismog is up to 6 times per year.
Speaker 3: We believe the Odyssey trial is balanced to meet its objectives effectively and efficiently with top-line results expected in Q3 2024.
Speaker 3: The Odyssey trial will compare CLSAX against the current standard of care Ilya or a flibre step
Speaker 3: In essence, we are comparing CLSAX maintenance versus a flibre-sub maintenance with a goal of demonstrating similar visual acuity outcomes with a lower treatment burden for the CLSAX arm.
Speaker 3: We plan to enroll a total of 60 treatment-experienced patients with WET-AMD. Patients will be randomized, or participants will be randomized two to one. Forty participants will receive CLS-AX administered by suprachoroidal injection via the ClearSight SCS microinjector. And 20 participants in the comparator arm will receive intravitreal Afliberseb.
Speaker 3: The trial will include participants diagnosed with wet AMD within 36 months of their screening visit and with a history of responding to anti-veget treatments for the disease. Participants will have reading center confirmation of persistent active disease.
Speaker 3: The primary outcome measures for this trial are the mean change in BCVA over 36 weeks, as well as the assessment of safety and tolerability of CLS-AX.
Speaker 3: The secondary outcome measures are treatment burden, as measured by total injections over trial duration, other changes in visual function and ocular anatomy such as CST, and the need for supplemental treatment.
Speaker 3: Participants in both arms will receive three monthly loading doses of a Liver Sub at 2MW.
Speaker 3: The second loading dose visit, defined as the baseline visit, participants in the CLSAX arm will also receive one milligram of CLSAX by supercoroidal injection.
Speaker 3: Participants in the comparator arm will also receive a sham Super Corridor injection to ensure masking of the trial.
Speaker 3: Participants in the CLSAX arm will then receive another CLSAX dose at week 24, unless they require supplemental treatment prior to that visit.
Speaker 3: Therefore, participants in the CLSA XR will receive at least two doses of CLSA X during the trial, which will provide valuable multi-dose safety information.
Speaker 3: for an end-to-phase 2 meeting with the FDA and the design of a phase 3 trial.
Speaker 3: In the comparator arm, participants will receive additional Afliversab injections every eight weeks until week 36, unless they require supplemental treatment prior to the scheduled every eight week Afliversab dose. Disease activity assessments will be conducted in both arms at week 12 and then every four weeks through week 32.
Speaker 3: This will determine if there is a need for supplemental treatment based on the occurrence of any one of the following four criteria compared to baseline.
Speaker 3: BCBA reduction of greater than 10 letters.
Speaker 3: an increase in the central subfield thickness of greater than 100 microns.
Speaker 3: BCA reduction of greater than five letters and an increase of CST of greater than 75 microns.
Speaker 3: for the presence of a new or worsening vision threatening hemorrhage due to wet AMD.
Speaker 3: The detailed trial design slides are available on our website in the corporate presentation.
Speaker 3: We believe this trial design makes sense for two key reasons. First, we are enrolling treatment experience participants with a history of responding to standard anti-VEGF treatments.
Speaker 3: We believe this will minimize recruitment of anti-VEGF sub and non-responders and may provide a larger population of participants to facilitate our trial enrollment efforts.
Speaker 3: Second, this trial is more closely aligned with the recent FDA draft guidance for wet AMD drug development by utilizing the Flibberecib as a comparator.
Speaker 3: BCVA as the primary outcome measure and utilizing a 36 week duration.
Speaker 3: Together, this will help us most effectively and efficiently prepare for a Phase 3 program in Wed AMD.
Speaker 3: Our clinical operations team has been working hard to get Odyssey up and running this quarter.
Speaker 3: I am pleased to announce today that the study will open for enrollment in the next few weeks, and we expect to enroll our first patient shortly thereafter.
Speaker 3: We are targeting a total of 30 US-based clinical trial sites and expect top-line data from the trial in the third quarter of next year.
Speaker 3: Moving on to Xypir.
Speaker 3: At our vote, Dr. Peter Chang presented survey data regarding the use of our SES microinjector from Retna, the UVI to specialists who have completed at least 10 supercoyle injections of Zypure.
Speaker 3: The findings from the survey of early adopters of Xypera suggest superchoroidal injection was easy to learn and patient improvements in vision and macular edema aligned with the findings in clinical registration trials.
Speaker 3: This broadening use of our supercoroidal delivery platform is encouraging as multiple clinical trials advance both with us and our development and commercialization partners.
Speaker 3: Our US and Canadian Commercial partner for Zipier Boson Lone continues to expand outreach with Zipier product education and SES injection awareness and training to healthcare providers.
Speaker 3: A significant number of physicians have been trained to date in the proper use of our SES microinjector. Falshes also filed for ZIPIA regulatory approval in Canada, so we're looking forward to market expansion than additional territory. Our Asia Pacific Commercial Partner for ZIPIA Arctic Vision is currently enrolling a confirmed
Speaker 3: Last week, Regenix Bio announced that they had completed enrollment in the expansion cohorts of Phase 2, AVI8, and Altitude Clinical Trials. These trials are utilizing supercroyal delivery of RGX 314 in patients with WEDAMD and diabetic retinopathy. Regenix Bio expects to report additional interim trial data from both trials, including initial data from the most recent cohorts in the second half of 2023.
Speaker 3: Vigenix Bio also announced that IND sponsorship has now been transferred to AbbVie for continued clinical development of the two superchloridol gene therapy clinical programs using Clearaside's SCS microinjective. AbbVie is a widely recognized global leader in eye care. In the future, RGX314 will be referred to as AbbVie, RGX.
Speaker 3: Our oncology partner, Aura Biosciences, is utilizing our SES micro-injector to deliver their viral-like drug conjugate belsar for the treatment of corridor melanoma. Based on promising data presented earlier this year, Aura announced spinal plans for its global phase III trial utilizing the Super corridoral lute of administration.
Speaker 3: They expect to begin dosing for the trial in the first half of this year.
Speaker 3: With that summary of our programs, I'll now turn the call over to our CFO , Charlie Degman, for a financial update. Charlie?
Speaker 4: Thanks, George, and good morning, everyone. Our financial results for the quarter were published earlier in our press release and are available on our website. Therefore, I will just provide a summary of our financial status. As George mentioned, we are making excellent progress in advancing CLSAX and we continue to prudently manage our cash balances we move forward with our programs. As of March 31, 2023, our cash and cash equivalence totals approximately $41.4 million. Based on our current outlook, we expect to have sufficient resources to fund our planned operations into the second quarter of 2024.
Speaker 4: We fully intend to fund the Odyssey study and we'll be exploring the best available options. On a financial housekeeping note, our current shelf registration is expiring so we plan to file a new shelf registration statement in addition to our 10Q.
Speaker 4: In the coming months, we will be participating in several investor conferences, including the JNP Life Sciences.
Speaker 4: conference next week and the WebBus PactRow Healthcare Conference in August .
Speaker 4: We look forward to these interactions and we'll keep you updated on our progress. I will now turn the call back over to George for his closing remarks.
Speaker 3: Thanks, Charlie. I'd like to wrap up with a few final comments. During the first quarter, we enhanced our scientific advisory board composed of industry leading retinal positions to obtain expert medical and scientific input for our clinical and preclinical research pipeline.
Speaker 3: Dr. Tom Chula now serves as the chair of our SAB, and we have also appointed two well-known retinal physicians as new members of our SAB, Drs. Arshad Khanani and Leila Vazovic.
Speaker 3: The entire Scientific Advisory Board has been instrumental in providing input into our Phase IIB clinical trial design, and we appreciate their ongoing guidance on all of our development programs.
Speaker 3: We look forward to the initiation of our ODYSSEY trial this quarter. We believe that the number of participants, the duration, and the outcome measures of the study will provide necessary clinical data to inform the CLS-AX Phase III program design.
Speaker 3: As we continue advancing CLSAX, we are excited about the potential for a potent, well-tolerated tyrosine kinase inhibitor in the multi-billion dollar wet AMD market.
Speaker 3: While we are intently focused on advancing CLSAX, we've also been very active intellectually behind the scenes on our science and SCS delivery.
Speaker 3: A research team is experimenting with more advanced injection designs, as well as other small molecule candidates that can be delivered into the supercordal space to target a number of rental diseases.
Speaker 3: In the optimal ophthalmic medical community, there's increasing acceptance for treating serious retinitis through the delivery of therapeutics behind the visual field into the supercroidal space. We believe this creates significant value for our proprietary SCS-micron-jector platform that provides a safe...
Speaker 3: in office, repeatable, non-surgical procedure to reach the back of the eye. We are well positioned to evaluate new collaboration opportunities along with tracking progress by our current partners.
Speaker 3: Our industry continues to generate exciting advancements and we're pleased to be a player in that development of promising new retinal therapies. We look forward to providing updates as we move forward.
Speaker 3: I would now like to ask the operator to open the call for questions.
Speaker 1: Thank you. As this time, we will conduct a question and answer session. As a reminder, 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, please press Star 1 1 again. Please stand by while we compile the Q&A roster.
Speaker 1: Our first question comes from Surge Bellinger of Meetham.
Speaker 5: Good morning.
Speaker 6: a couple questions. Good morning. First one.
Speaker 6: In the past you've mentioned that the the Odyssey trial was not powered for superiority or non-inferiority so how should we think about a successful outcome for for this trial? And secondly I think looking back at the Oasis trial
Speaker 6: I think in one of the cohorts there were some issues in how physicians were assessing the retreatment criteria.
Speaker 6: Just curious how you plan to minimize that as an issue for the Odyssey trial. Thank you.
Speaker 3: Okay, thanks for the questions, sir. On the first question, you're correct. Would this study is not powered to be a non-inferiority study or a superiority study per se?
Speaker 3: What we're doing is we're trying to, a successful trial for us would be to show a lower treatment burden as I mentioned by looking at the number of injections over the trial period.
Speaker 3: with our maintaining stable visual acuity.
Speaker 3: What we're doing here is we're really looking for means and percentages that give us an estimation of how we would go into phase three on a fixed dosing schedule. So we don't need to do this in phase two, and this is not that uncommon, is to go into phase two and not...
Speaker 3: not power it in such a way as to be a non-inferiority trial. What we're trying to do is basically find our best estimate of what the lead.
Speaker 3: The fixed dosing schedule would be to go into a non-inferiority trial in Phase 3. So we're not doing it, we're setting up or gathering the data in order for us to properly design and power a Phase 3 program in wet AMD. So this is what we're going to do in Odyssey.
Speaker 3: is gain that estimation of what we need to do in order to design the proper case 3 trial. Also, we're trying to engage where we're going to end up in terms of FDA, the final FDA guidance on trial design and wet AMD, as you know that the FDA produced the draft guidance and there's a comment period and believe it ends.
Speaker 3: would be for us as I said, a lower treatment burden.
Speaker 3: And we would be very happy if we see the vast majority, if not all the patients going at least four or six months on their duration post the loading in period versus a Flibberezab being dosed every eight weeks. There was a second part to your question. I'm sorry, I've forgotten it now, so.
Speaker 6: No problem. It was about the assessment for retreatment. I think there are some issues with the interpretation of that in OASIS.
Speaker 3: Yeah, we've taken a number of steps to try to decrease those variations from protocol, protocol that we've enhanced the training, we've enhanced the on-site supervision. We have a computer program that directs the positions as to what to do exactly the measurements in office.
Speaker 3: have been done in a more stringent way. So we were very, very cognizant of some of those off protocol rescues. And as you recall in the OACs data, those off protocol rescues, when they were assessed by the independent reading center, most of them should not have been treated. So they should not have been rescued. So we've been very cognizant of that and set up a very rigid protocol to try to eliminate that. I'm not sure we can eliminate all of that, but we've done our best to try to minimize it, if not eliminate it.
Speaker 7: Thank you.
Speaker 1: Please stand by for our next question.
Speaker 1: Our next question comes from Annabelle Simimi of Stifle.
Hi, thanks for taking my question. I am a bill. Good progress. How are you? I had a couple of questions. One is just going back to the phase two design as you're talking about having not designed it for superior to 9th and period already. I guess.
FDA is not going to be booking at lower treatment burden as an actual endpoint and phase 2 correct or in phase 3. That's never going to be one of their end points. It's always going to be BCVA safety and duration. So just want to make sure we're clear that we know what the...
that the end points have necessarily changed as we go into phase three, but you're just looking right now at treatment burden. We're looking at maintaining a stable visual acuity and we're doing a treatment burden. And the reason for it, you're right about what the draft guidelines say. We understand that. He was very clear that the doctor chambers and the group were very clear.
Obviously going into phase three, unless the draft guidelines change with their final version, treatment burden would not be a primary endpoint in and of itself in a phase three trial and the FDA's made that pretty clear. It's very clear they're focused on safety and they're very clear they're focused on vision. So we understand that, but this is more to give us the question.
on the draft guidelines.
I guess, what are some of the potential changes you might possibly be facing to these guidelines? I mean, are they contemplating potentially a different standard of care with the BISMO, or is there something else that they're contemplating that—or from what you understand as being Is there something that might be more personal?
I guess costs around different ideas of new guideline requirements. I don't have any insight into what the FDA might be considering. This is their first shot across the aisle. I expect that there'll be comments coming in from many corners of the industry to either seek clarification or suggest.
possible changes to this. I would think it's possible over time that they may add something like Bivismo as an acceptable or even, Bivismo in particular makes, find that acceptable as a comparator. But I don't think the time, they're clear now that that's.
not their position. That could change over the next year or two. But as far as what they plan, I think this is their plan. They're going to let the industry comment on it. I'm not sure where it's going to come out. I think there are some things about the...
the comparator arm that we're a little unclear to some of us in the industry and either require clarification or change. But we'll see, you know, we've had those, we've had some conversations with the agency as I'm sure all the other companies have and we think we understand it well enough for at least the Odyssey trial and know what we need to do there.
Can you just help us understand why you might want to minimize that population? And if you do have sub responders, you're going to be doing these different analyses within the trial to...
I don't know, just separate them out or identify different responses based on their stages of disease. 1
Well, you know, what we're really trying, we're trying to get, based on the conversations we've had with our KOLs and our Scientific Advisory Board, we're trying to get the largest, most relevant population to them.
that we can enroll them here. And if you remember the OASIS trial, they were treatment experience, but they were heavily treatment experience. These were people that were referred to as anti-vegetics. They were being treated much more, you know, frequently than even the label indication for either for the antivigettes that they were on. We're not looking for that group. We're looking for a group that has shown a positive response to antivigettes.
but is not in the category of their needing, like a Flibberefib every four to six weeks, instead of every eight weeks. We're not looking for the really difficult to control patients, but we're not looking for patients that are naive either. So we're taking patients that have had some treatment response, some treatment history.
and seeing what we can do when we compare ourselves to Aflirib. We're trying to get a more, we're trying to keep a fairly homogenous group of patients, not trying to get a lot of sub-responders, and then we have to go in and do a lot of analysis. We're just trying to take this big group that we think is the most relevant group, certainly in the opinion of our KOLs.
Our next question comes from Jonathan Willbene of J&P. Hi, this is Catherine of Kony on for John . And we just have a question about what non-reality margins you want to hit in terms of BCDA, Up America.
Ultimately, I know in Odyssey you guys said that it's not powered for non-fear, but what would be the goal? In unison we,Toddler,-------
You mean in terms of I'm not sure I quite understand the question. What's what? This is as far as I guess what groups yeah between between the Aaliyah arm and then the your treatment arm or be kind of the margin that you guys would be looking for. I think we have to put in about four letters for five letters plus or minus. But it's comparable, it's we're just looking for comparable.
stable comparable BCVA. It's certainly going to have to be clinically acceptable, that's for sure, but I think between the two groups as long as within a couple letters of the two groups will be fine. Great, I have one follow-up question to that. As far as the reduction in treatment burden versus longer duration, which do you feel is more meaningful?
treatment burden.
I mean if you look at that period of time, you know, you're going to get the three Yeah, so three of liver seb injections to one CLS-ax injecting so that duration feeds directly into treatment burden reduction. It's it's more convenient for the patient for the caregivers or you know and for on a reimbursement basis, so it's
It's better all around, you know, and there's many of us that are trying to have this extended duration of therapy. It's better all around for the, you know, for patients and for payers and for caregivers that you can maintain stable visual acuity and not have to be injected, you know, every four to eight weeks. So I think the two are directly related.
What would be kind of a meaningful result as far as the measure goes in terms of time and then in terms of the duration between treatments.
Right now we're looking at, you know, we're hoping that all of our patients go at least for and the vast majority go to six months in terms of duration.
I mean, because if you look at what's now in the market, Bivisumone says, for example, it can be up to four months, but we know that over half their patients need to be retreated before three months. High-dose Ilea is being up for approval, and they're asking for approval.
between three and four months after quadrupling the dose. So we think there's a lot of room for improvement and an excitement by physicians if we can be over four weeks up to five and six weeks. Really our target is trying to have a twice a year or every six months. Excuse me, I said weeks. Every will go four months to six months.
I target really our hope that we have a twice a year product. Thank you so much. Thank you. Please stand by for our next question.
Our next question comes from Andreas Arderaite of Whitbush.
I don't go. Good morning guys, I think you're taking a question here. So just maybe a follow up to some that have already been asked in a different way here. So thinking about, or you know, heading into Odyssey here, what is the bar for efficacy in terms of percentage of injection frequency reduction and percent of patients rescue free given kind of some of the data that you've seen with competitors? And then...
conjecture. So, you know.
without rescue. So we're looking for basically the lowest degree of rescue possible in the CLSAX group. I mean, it's also possible even in the comparator group of the Flibersev that they're gonna need treatment in between their every eight week doses. So we're looking at that and we're very.
We think that we're going to get the vast majority of our patients go without need for supplemental therapy at least for and hopefully the vast majority go five or six months. So that's really all I can tell you. I don't. You know, other groups that have done this have had to have rescue other groups that are studying that certainly the piracy and time.
did an OASIS and like we intend to do in Odyssey is make sure that patients that are being enrolled have active disease. All of them need to have active disease so we know that patients require medicine. Right? We do not want to enroll anybody in our trial and we're trying very hard to prevent this that may never need treatment.
over the trial duration period. I mean, there's a significant literature that supports people within that have been diagnosed but have inactive disease or they're completely dry on diagnosis may not require any treatment for six months. Just watchful waiting. So we want to eliminate that. That we want to know.
If we have something that really works, and so we want to put our drug in patients that we know for the best of our ability will require treatment. And so hopefully in our arm, there's very few, if any, need for supplemental treatment, and that the vast majority of the patients go forward with.
six months after receiving their initial dose of CLS-AX. On the BD front, we continue to have active discussions with a number of companies that are interested in accessing the super colloidal technology that we have.
We're the only technology that's been used in the clinic.
So people know if we're clearly the leader in administering drugs in the supracorital space and people know that if they want to get there and they want to get there in a proven way and a reliable way and a safe way.
Our next question comes from Yi Chen of HC, Wayward & Co.
Hello?
Yes, hello, you. Hi, sorry. Thank you for taking my question. My first question is, could you give us some additional color on the side here, launch, and how should we project the license revenue going forward?
All right, you please repeat. I was asking that you give us some additional color on the ZYPEER commercial performance and how should we project the licensed revenue going forward?
Okay, Charlie, you want to take that question?
Sure, yeah, so from Zypyr, as we all know, Bausalom has launched that product. They've been very active, training more than 1,000 retinal specialists in the U.S. to use Zypyr. I'm sure it had positive feedback, but…
talk about their sales and when they're ready to they will report on it. So I can't give you any insight into Bausch's sales.
being else sales. And then from partnering estimates, we don't give out a revenue forecast, but there are some licensing milestones, nothing.
major coming up, I would assume, as some of our partners move into different phases in their clinical study. But sorry, we don't give a forecast on our partners.
in patients. Do you think in real-world practice long-lasting what AMD treatment will ever be used on treatment- naive patients?
of treatment naive, but I do think that eventually as more data is obtained on ours and other products, I do think that more extended duration treatment will become more than norm. Obviously, physicians will.
will work based on data. But as that data is accumulated, I think they will. Now, there's a difference between saying they'll use extended duration and will they extend the duration of patient visits to the physician's office.
I think that I can't really comment on what physician practices would be, but in our estimation, and I think in others' estimation, it's not really going to change significantly the number of times per year a physician.
wants to see a patient, but I think it would, with extended duration, as it gets more, as more data is developed, I think it could make a small difference. For example, if patients with weight-aimed care are being seen monthly, they may go to being seen every other month.
and then they may not need to be injected on every visit, but if they're being seen every month and demonstrating stable BCBA and the degree of fluid is holding reasonably stable, maybe they're injected every other visit, so they're being injected four times a year.
but only seeing the doctor six times a year, but being injected three times a year or two times a year. So I do think it will eventually change the practice. In our conversations with KOLs, they're very excited about seeing durations longer than two months.
You can see from the uptake of the bismill right now where it has the opportunity to go to every four months, but not to guarantee because again, like I said earlier, over half their patients needed to be retreated by three months. There's been a tremendous uptake in the bismill with that small incremental gain.
So I think if you were able to show that with very solid data, you can dose somebody and maintain stable visual acuity and keep the fluid in the retina under control for four to six months with solid data, I think that will change the treatment paradigm eventually in the physician's office.
Thank you. Thank you. I would now like to turn it back to Dr. Lozewski for closing remarks. I want to thank everyone for joining us this morning on the call.
