George Lasezkay

Thank you, Remy, and good afternoon, everyone. As we near the midpoint of 2024, I'm excited with the progress we have made to date, which has positioned Clearside for an important year. Recently, we added two key positions to our team for having an immediate and meaningful impact on our organization.
In March, we welcomed Dr. Victor Chong as our Chief Medical Officer. Victor is a well-respected board-certified retinal specialists with more than 25 years of experience advancing drug candidates through all stages of development, including the development of ranibizumab and aflibercept for wet AMD.
Most recently, Victor served as Global Head of Retina at Johnson & Johnson, and prior to that, he was Global Head of Medicine in Retinal Health at Boehringer Ingelheim.
His extensive experience is extremely valuable as the spearheads our product development activities led by the upcoming ODYSSEY data analysis, and the planning for our CLS-AX Phase 3 program. Victor will be discussing these shortly.
Last month, we also added seasoned biotech executive, Tony Gibney, to our Board of Directors. Tony has a deep understanding of the biotechnology business and combined with recent and relevant ophthalmology experience at Iveric Bio, where he was Chief Business and Strategy Officer.
Tony has broad expertise in collaborations, finance, and M&A that will help guide our strategic and business development initiatives as we explore future value-creating opportunities for Clearside. These personnel additions are important as we continue to build on our leadership position in suprachoroidal delivery.
Our SCS Microinjector technology has been used in thousands of injections in the clinic, and continues to demonstrate a strong safety record that includes no cases of endophthalmitis to date.
As the pioneers in delivery to the suprachoroidal space. We are proud of the breadth and depth of our pipeline that includes our internally developed assets as well as those from our collaborators in a broad range of retinal diseases.
With that, I'd like to now introduce our new Chief Medical Officer, Victor Chong, who will provide his perspectives on joining Clearside and our programs. Victor?

Victor Chong

Thank you, George, and good afternoon, everyone. Let me begin by saying it is a pleasure to speak with all of you today as a member of the Clearside team. I have been on board for almost two months now, and I'm extremely excited by the prospect of our drug device technology, as well as our broader pipeline.
I wanted to share some of the reasons I chose to join Clearside from J&J. First, I believe the suprachoroidal platform is an important but undervalued approach to treat retinal diseases. Clearside is leading the way initial lucrative delivery by a very big margin, including having the only FDA approved product for suprachoroidal use.
With my background as a physician scientist, combined with almost a decade in large pharma, I look forward to leading our team as we approach our ODYSSEY data readout, and begin planning our Phase 3 program for CLS-AX.
And finally, I can utilize my translational expertise in advancing new molecules into the clinic and see many opportunities to see our company's device and formulation platform to potentially expand our pipeline into areas such as geographic atrophy.
Today, I want to focus on CLS-AX, and the differentiators for the drug, and the ODYSSEY clinical trial. The current wet AMD market is driving more than $12 billion annually in sales.
While the existing approved therapy are effective, including faricimab and high-dose aflibercept, they are delivered individually and only lasts up to four months in some patients. We believe CLS-AX may extend the time between doses for up to six months for most patients, which could meaningfully reduce the treatment burden for patients, caregivers and payers.
I find the ODYSSEY trial to be a compelling design that is differentiated from many of the other mixed phase wet AMD studies. First, the trial was designed to allow retreatment with our own drug candidate, if needed five to six months, which is similar to the anti-VEGF currently on the market.
In addition, the protocol mandate participants in the CLS-AX arm to be redosed at month six, if not previously retreated. Wet AMD is a chronic disease and retreatment is essential. This multi-dosing data will help inform our CLS-AX Phase 3 development program.
Second, the trial duration of 36 weeks allow us to follow patients beyond six months. This is close to the duration required for primary endpoint by the FDA for Phase 3 trial in wet AMD. It allows us to translate our CLS-AX Phase 2b results to Phase 3 trial design more easily.
And finally, ODYSSEY is treating patients with confirmed active disease, so we will have a dataset on patients who definitely need retreatment.
I'm pleased to report that ODYSSEY is progressing as planned, and we expect to have top-line results at the end of the third quarter of this year. Our target profile for CLS-AX is to maintain visual acuity without the need for retreatment for potentially up to six months.
We expect that the final Phase 2b data will provide important insights to create a robust Phase 3 development program for CLS-AX.
I'm looking forward to this journey at Clearside, and will now turn the call over to our CFO, Charlie Deignan, to provide a financial update.

Charles Deignan

Thank you, Victor, and good afternoon, everyone. Our financial results for the first quarter 2024 were published earlier in our press release and are available on our website. Therefore, I will just provide a summary of our financial status on today's call.
As of March 31, 2024, our cash and cash equivalents totaled approximately $35 million. We believe we have sufficient resources to fund our planned operations into the third quarter of 2025. This takes us through the anticipated data readout for the ODYSSEY trial this year and supports planning our CLS-AX Phase 3 program.
We will be participating in the Citizen's JMP Securities Life Sciences Conference next week, and we look forward to keeping you updated on our progress. I will now turn the call over to George for his closing remarks.

George Lasezkay

Thank you, Charlie. We expect 2024 will be a transformative year for Clearside. We are committed to maintaining our leadership role in the suprachoroidal space, as we and our partners generate additional clinical data demonstrating the potential benefits of drug delivery with our SCS Microinjector.
We believe that the data readout from ODYSSEY later this year will demonstrate that CLS-AX could be a valuable addition to the treatment regimen in the multibillion-dollar wet AMD market.
Our efforts in developing suprachoroidal drug delivery have the potential to change the treatment paradigm for serious retinal diseases, and provide a lasting positive impact for patients, physicians, and our shareholders.
I would now like to ask the operator to open the call up for questions.

Question and Answer Session

Jon Wolleben, JMP Securities

Jon Wolleben

Hi, good afternoon. Thanks for taking my question.

George Lasezkay

Hi, Jon.

Jon Wolleben

Hi, George. I was hoping to just get a reminder on what constitutes active disease as the inclusion criteria for ODYSSEY and how that differs from other mid-stage wet AMD trials?

George Lasezkay

Okay. Victor, I think that's a great question for you. So why don't you take that one?

Victor Chong

Yes, Jon. How are you? On the protocol that we would require, the patients that still have subretinal fluid or intraretinal fluid or the fluorescein angiography is showing leakage.
So that is what we would define as still remain to have active disease. Because some patients would have been treated, and then they were already dried, and might not be further treated.

Jon Wolleben

Okay. And can you talk a little bit about how you think about CLS-AX in comparison to the other TKIs in development?
And then, also, we talk a lot about durability, but how do you feel about the data package you'll provide? And what is most important for investors to keep in mind as they're interpreting the readout in 3Q?

Victor Chong

Yes. So when you say comparing different companies that two TKIs are in play, axitinib is the one that we have sharing with Ocular Therapeutics, and then EyePoint has another TKI.
And in terms of that we believe that anti-VEGF is most important, and among the entire anti-VEGF IC50 is significantly lower in axitinib, and in other words that they are much more potent.
I am sorry, I missed the second question. Can you just quickly repeat that?

Jon Wolleben

We talk about durability as a key thing to look at in these late-stage trials. [Last year we worried more] about BCVA, burden of treatment, if you had to think about the endpoints you'll be giving us, what should we focus on?

Victor Chong

Yes. So I think that's a very good question. But I think that at the moment, we are still waiting for our Phase 2 results. At the same time, that would help us to inform our Phase 3 design. But I think that, as I mentioned in my webcast discussion earlier already, that at least that we have data that have retreatment.
So every patient in ODYSSEY will be at least retreated ones, even if they have been doing okay up until six months. So that retreatment data will get us to nine months and longer, and also our trial is also nine months.
So again, that's closer to the FDA requirement for the primary endpoint. I would say visual acuity, end of the day, is the most important. And I think that will be something that we were focusing on how that we can measure the visual acuity that will meet the requirement of the FDA as well as other agency around the world.

Jon Wolleben

Okay. That's helpful. Thanks again for taking the questions.

Victor Chong

Thank you Jon.

[Jaiadam Mung], Stifel.

Hi, thanks. This is Jaiadam calling in for Annabel. I have two questions for you. First question, realizing that you're still in Phase 2 trials with CLS-AX, have you given any further thought to the Phase 3 design, in light of some of your competitors funding superiority trials to standard of care?

George Lasezkay

Well, let me say first that what we're doing now, while we're waiting for our Phase 2b data to come in is we are undergoing internal planning for Phase 3, depending on how the data comes out. So we're already looking at that. We're discussing Phase 3 trial designs with our consultants. And that's all under evaluation at this time. But Victor, do you want to add anything to that?

Victor Chong

Yes. I think that, as I mentioned earlier, that we are still working on it. And there is a number of options that we are considering. But at the end of the day, the key difference for us to somewhat is that we can retreatment based on our own drug.
So that could be a major difference in the study design that some other TKI companies might not be able to do. So again, surrounding that is something that we will see how that we can maximize our advantage at the same time providing future retinal specialists in the future to use our drug more easily.

Great. Thank you.

George Lasezkay

You had a second question?

Yes, I did. Thank you. The second question was in regards to the FDA, have they come any closer to establishing new clinical trial guidelines based on the shifting treatment paradigm, namely [lavisinol]?

George Lasezkay

You mean have they started to plan or come close to finalizing their draft guidance, their previous draft guidance, that was like over a year ago? For wet AMD trials? Is that what you're talking about?
Victor, you might be more up to date on where you think the FDA is based on our recent conversations.

Victor Chong

Yes. I think that when the guideline are more than a year old, and it is still not finalized, and obviously that the community has some potential concern, but yes, that is not unusual for FDA to have a draft guideline for a long time as well.
So it's hard to predict, but that suggested that some of the point on the guidelines was inconsistent with practice. So again, those are the something that I think everyone are discussing in multiple different conferences, in the multiple different platforms.
But again, exactly when that draft guideline will become finalized or even moving to interim is still difficult to be sure. And especially, as you know, that there's a recent leadership change in FDA as well, that may be related as well.

George Lasezkay

And obviously, as we go forward before we announce any Phase 3 plans, we will have been engaged at least once, if not multiple times with the agency to discuss Phase 3 trial design. So we'll get the most up-to-date reading from the agency in our conversations with them as our planning continues.

Got it. Thank you. Thanks for your thoughtful answers.

George Lasezkay

Okay.

Operator
