[George Lasezkay, executive]

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 2 key positions to our team who are 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 specialist with more than 25 years of experience advancing drug candidates through all stages of development including the development of rademizumab 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. Victor's extensive experience is extremely valuable as he spearheads our product development activities, led by the upcoming ODYSSEY data analysis and the planning for our CLS-AX Phase III 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 IbericBio, 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 of 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 endolphalitis 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, executive]

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 CSI team. I have been on board for almost 2 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 in the suprachoroidal 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 III 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 AMD market is driving more than $12 billion annually in sales, while the existing approved therapy are effective, including resume and high-dose fives app, they are delivered individually and only lasts up to 4 months in some patients. We believe CLS-AX may extend the time between doses for up to 6 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 study. First, the trial was designed to allow retreatment with our own drug candidate, if needed prior to 6 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 6, if not previously retreated. Whether in the is a chronic disease and retreatment is even -- this multi-dosing data will help inform our CLS-AX Phase III development program.

Second, the trial duration of 36 weeks allow us to follow patients beyond 6 months. This is close to the duration required for primary endpoint by the FDA for Phase III trial in wet AMD. It allow us to translate our CLS-AX Phase IIb results to Phase III trial design more easily.

And finally, ODYSSEY is treating patients with confirmed active disease so we will have a data set 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 with equity without the need for retreatment for potentially up to 6 months. We expect that the final Phase IIb data will provide important insights to create a robust Phase III 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.

[Charlie Deignan, executive]

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 III program.

We will be participating in the Citizens 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, executive]

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.

[Operator]

[Operator Instructions] Your first question comes from Jon Wolleben with JMP Securities.

[Jonathan Wolleben, analyst]

I was hoping to just get a reminder on what constitutes active disease as the inclusion criteria produce and how that is from other mid-stage trials?

[George Lasezkay, executive]

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

[Victor Chong, executive]

Yes, Jon, on the protocol that we would require the patients that still have foresaid or insurer for it or the foresensing leakage. So that is what we would find and still remain to have active disease because some patients would have been treated and then they already drive and might not be service treatment. .

[Jonathan Wolleben, analyst]

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, what is -- we talk a lot about variability, but how do you feel about this 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, executive]

Yes. So when you say comparing different companies that 2 TKIs are in play, is the 1 that we have sharing with offer therapeutic and the iPhone have another TKI. And in terms of that we believe that antibater is most important. And among the entire base IC50 is certainly lower even -- and in other words, that they are much more potent.

In terms of sorry, I missed the second question. Can you just quickly repeat?

[Jonathan Wolleben, analyst]

We talk about durability as a key thing to look at in these late-stage trials last year we'd worry more about BCGA, burden of treatment? What -- if you had to think about the endpoints, you'll be giving us, what should we focus on?

[Victor Chong, executive]

Yes. So I think that's a very good question. But I think that at the moment, we are still waiting for our Phase II results. At the same time, that would help us inform our Phase III design. But I think that, as I mentioned in my webcast that discussion earlier already, that at least that we have data that have the treatment.

So every patient in ads will be at least retreated ones, even if they have been doing okay up until 6 months. So that recruitment data will get up to 9 months and longer. And also our trial is also 9 months. So again, that's closer to the FDA requirement for the timing endpoint I would say with acuity end of the day is the most important.

And I think that will be something that we were focusing on how to we measure the reactivity that will require -- that will meet the requirement of the FDA as well as other agency around the world.

[Operator]

Your next question comes from Jay Mom with Stifel.

[Unknown Analyst]

This is Jae I'm calling in for Annabel. I have 2 questions for you. First question, realizing that you're still in Phase II trials with CLS-AX. Have you given any further thought to the Phase III design in light of some of your competitors funding superiority trial to standard of care?

[George Lasezkay, executive]

Well, let me say first that what we're doing now, while we're waiting for our Phase Ib data to come in is we are undergoing internal planning for Phase III, depending on how the data comes out. So we're already looking at that. We're discussing Phase III 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, executive]

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 the end of the day, then 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 may 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 better specialists in the future to use on drug more easily.

[George Lasezkay, executive]

You had a second question?

[Unknown Analyst]

Yes, I did. 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, mainly is no .

[George Lasezkay, executive]

You mean have they started to plan come close to finalizing their draft guidance, their previous draft guidance that was like over a year ago for wet AMD tiles. 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, executive]

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 have a draft guideline for a long time as well. So it's hard to predict, but that suggest that some of the corn on the time line was in consistent with practice.

So again, that is also something that I think everyone are discussing on multiple different confers multiple different platforms. But again, exactly when that the draft prior becomes finalized or even or moving to interim is still difficult to be sure. And especially, as you know, that there's a recent ship change in FDA as well that whether there might be lasting as well.

[George Lasezkay, executive]

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

[Operator]

I would now like to turn the call back to George Lasezkay for any further remarks.

[George Lasezkay, executive]

Well, I want to thank everybody for being on the call today. We look forward to keeping you apprised of our progress. And with that, I would say that the operator, you can end the call. .
