Thank you, Tiffany, and thank you all for joining us today. As detailed in our press release, we are excited to discuss the substantial progress of our game-changing modifier gene therapy platform by using nuclear hormone receptors to restore homeostasis in the retina. Modifier gene therapy has the potential to address multiple inherited retinal diseases as well as larger multifactor diseases, such as dry age-related macular degeneration, through a gene-agnostic approach. Just after the close of the first quarter of this year, we announced that the FDA cleared our IND application for the OCU400 Phase III liMeliGhT clinical trial and the EMA provided acceptability of the U.S.-based trial for submission of the market authorization application. I will discuss the significance of these milestones and the potential for OCU400 in greater depth later in the presentation. OCU410 and OCU410ST are now in Phase I/II clinical trials, targeting geographic atrophy secondary to dry age-related macular degeneration and Stargardt disease, respectively, with the clinical updates expected in the third quarter of 2024. Our cell therapy platform is poised to advance with the renovations to our existing facility completed earlier this year. This gives Ocugen the capability to support NeoCart autologous cell therapy manufacturing for personalized Phase III clinical material contingent upon adequate funding. Finally, OCU400 will soon advance into a Phase I clinical trial via National Institute of Allergy and Infectious Diseases, NIAID sponsored trial comparing the administration of OCU400 via two different mucosal routes, inhalation into the lungs and as a nasal spray. With three gene therapy candidates to treat blindness diseases in the clinic and the Phase III ready cell therapy candidate, we are confident that 2024 will be a bellwether for Ocugen. We are thrilled to share significant advancements in our leading modified gene therapy candidate, OCU400, as it makes remarkable strides in clinical development. The green light from the FDA to begin the Phase III clinical trial marks a pivotal milestone as OCU400 becomes the first gene therapy to progress to Phase III trials with such a broad retinitis pigmentosa indication. Until now, there has been only one market product to treat one of the 100 gene mutations associated with RP. Now, there is real hope for all RP patients who haven't had a treatment option. Our completion of enrollment and dosing in the Phase I/II trial demonstrated promising safety and efficacy across various genetic mutations and dosage levels, paving the way for the Phase III clinical trial. OCU400 has already received key regulatory approvals, including orphan drug, regenerative medicine advanced therapy and orphan medicinal product designations from both the FDA and European Commission for treating inherited retinal diseases. These endorsements highlight OCU400's broad therapeutic potential, and we remain on track to meet 2026 BLA and MAA approval targets. We expect to begin dosing patients in the Phase II liMeliGhT clinical trial in the second quarter of 2024, which will include 150 subjects across two arms, one with patients affected by specific mutations and one arm that is gene-agnostic. Luminance dependent navigation assessment, LDNA, the primary endpoint for the study, focuses on the proportion of responders in treated and untreated control groups, achieving an improvement of at least 2 lux level from baseline in the study eyes. The secondary endpoint will be measured by changing low-luminance visual acuity score from the baseline. The effectiveness of the treatment will be compared to an untreated control group for the secondary endpoint as well. Additionally, leveraging a dual-track strategy, we plan to expand the Phase III trial in the latter half of 2024 to include patients with Leber congenital amaurosis, LCA, contingent on favorable results from Phase I/II study. Let me take a moment to discuss the unmet need and underserved market for RP and LCA patients; an estimated 1.6 million people globally are affected by RP and LCA combined. In the U.S. and Europe alone, our initial target markets, there are nearly 300,000 total patients. RP and LCA are classified as inherited retinal diseases from a group of heterogeneous disorders that affect the retinal cells. These conditions frequently result in visual impairment and ultimately, blindness. By establishing homeostasis in patients affected by these diseases, our aim is to preserve or improve vision. By actively sharing our insights or pertinent medical conferences and engaging with advocacy groups, we strive to raise awareness of the desperate need to find a solution for our RP and LCA patients as well as the potential of modified gene therapy to revolutionize treatment. To better understand the experience of one of our Phase I/II clinical trial patients, I encourage you to watch his video in the patient section of our website. Moving on to our development in the treatment of geographic atrophy, secondary to dry age-related macular degeneration and Stargardt disease with our OCU410 and OCU410ST programs. These modified gene therapies leverage the nuclear receptor gene, RAR-related orphan receptor A (RORA), aiming to provide a potential onetime therapy for life with a single subretinal injection. OCU410, specifically designed to address multiple pathways implicated in the pathogenesis of dry AMD, offers a distinct advantage over current treatments which target only one cause of GA and often require multiple injections per year accompanied by various safety consultations. Our approach with OCU410 is to provide a comprehensive and durable solution, a potential onetime therapy for life. Dry AMD affects about 19 million people in the U.S. and Europe combined, while GA affects about 2 million to 3 million people in the U.S. and Europe, representing a significant market opportunity. In December 2023, we began the Phase I/II ArMaDa clinical trial for OCU410. Considerable progress has been made with the completion of dosing in both the first and second cohort, low and medium doses. Following the successful dosing in this cohort, the Data and Safety Monitoring Board (DSMB) will convene later this month to evaluate proceeding with the high-dose cohort in the ongoing dose escalation phase of the study. After completion of the third cohort, we will transition into Phase II clinical trial, the expansion phase. A key upcoming event for this trial is a clinical update, which is anticipated in the third quarter of 2024. This data will provide initial insights into the safety and efficacy of OCU410. OCU410 Phase I study is multicenter and open label focusing on dose ranging, while Phase II is randomized, aiming to expand our understanding of drug efficacy and safety compared to a control untreated arm, with patients randomized in a 1:1:1 ratio across two dosage groups and one controlled group. Participants must be aged 50 or older, have a best corrected visual acuity of approximately 24 letters or more using the ETDRS chart and have a total geographic atrophy area between 2.5 million and 20.5 square millimeters. We now turn to OCU410ST, which received orphan drug designation from the FDA for the treatment of ABCA4-associated retinopathies, including Stargardt disease. Stargardt affects approximately 100,000 people in the U.S. and EU combined. This modified gene therapy candidate also utilizes the RORA gene in the Phase I/II GARDian trial for Stargardt disease and is actively enrolling patients. We have completed dosing in the first cohort (low dose). In April 2024, the Data Safety and Monitoring Board approved the continuation to the medium dose phase, which we expect will be completed this month. A clinical trial update for OCU410ST is also anticipated in the third quarter of 2024. The Phase I/II trial involves up to 42 participants, 30 adults and 12 children, who exhibit mild-to-moderate disease symptoms. The study uses a 3+3 dose escalation design in Phase I, segmenting subjects into low, medium and high dose cohorts. Following the dose escalation phase, the trial will transition into Phase II, the expansion phase. This expansion phase will use a 1:1:1 design to randomize subjects into two different treatment groups at the varying dose levels or a controlled untreated group, allowing for a comprehensive assessment of treatment efficacy across different dosages. Our work across OCU400, OCU410 and OCU410ST demonstrates our enduring commitment to the success of these modified gene therapies for the benefit of patients faced with the terrible prospect of losing their sight. We are encouraged by the progress in these trials and look forward to sharing further updates as we reach critical milestones and get closer to addressing substantial unmet medical needs. With that, I will now turn the call over to our Corporate Controller to provide an update on our financial results for the first quarter ended March 31, 2024.

Thank you, Shankar. Our research and development expenses for the quarter ended March 31, 2024, were $6.8 million compared to $10.2 million for the first quarter of 2023. General and administrative expenses for the quarter ended March 31, 2024, were $6.4 million compared to $8.3 million during the same period in 2023. Net loss was approximately $11.9 million or $0.05 net loss per share for the quarter ended March 31, 2024, compared to a net loss of approximately $17.3 million or $0.08 net loss per share for the first quarter of 2023. Our cash and cash equivalents totaled $26.4 million as of March 31, 2024, compared to $39.5 million as of December 31, 2023. As always, we are constantly exploring strategic and shareholder-friendly opportunities to increase our working capital. That concludes my update for the quarter. Tiffany, back to you.

Thank you, Mike. We will now open this call for questions. Operator?

Your first question comes from Arthur He with H.C. Wainwright.

Sean Canty, congrats on the progress. So I just had a quick one regarding the 400 Phase III study. Rick, for the gene-agnostic arm, is there a minimum number of patients for each specific gene mutation to meet the requirement for the BLA application?

Arthur, I'll let Arun take that to respond.

No, we have not prespecified any specific number of patients for each mutation, but our approach is going to be to include as many mutations as possible in the gene-agnostic count.

Okay. And also, my second question is regarding the 200. Could you give us more color on the status and what's your effort to get the clinical hold lifted as soon as possible?

Yes. So we are working on addressing the CMC question we received from the FDA, and we are planning to address that as soon as possible and then continue the development of OCU200 further.

Your next question comes from Robert LeBoyer with NOBLE Capital Markets.

Congratulations on all the progress during the quarter. My question has to do with the Phase III trial coming up. And you had mentioned some milestones to start. Are there any time frames or any particular milestones that we can look forward to in terms of accrual or projected time or data release?

Yes. Robert, I'll let Dr. Qamar answer the question.

Thank you for your question. In terms of the milestones, as you are aware, OCU400 has recently got approval. We are currently screening patients and we will be continuously updating the market with dosing updates very soon.

Okay. Is there any projected time for the first data release?

For OCU400 Phase III or Phase I/II?

Either at...

Okay. So Phase I/II, we have already updated that. Continuous updates would be coming in the next quarter as well. And as soon as we receive more data on the NCA patients. For OCU400 Phase III, there is no timeframe as it will be periodic, and we will be giving periodic updates to the market as soon as it's available.

Yes, Robert, I think this is a controlled clinical trial for Phase III. Until the study is completed, we cannot disclose any information to the market regarding its efficacy. We will provide regular updates, as Dr. Qamar mentioned, on recruitment and the progress of the trial, and we will also inform the market about our target timeline for securing BLA and MAA approval in 2026.

Your next question comes from the line of Daniil Gataulin with Chardan.

Also a question on OCU400 and Phase III. So you mentioned that as part of a dual-track strategy, you will be expanding Phase III to include patients with LCA pending the Phase I/II LCA data. I just wanted to clarify this will be added as a new arm in the trial or if it will be a separate stand-alone trial? And I guess the second part of the question is what data from LCA Phase I/II would you consider favorable that would give you a go-ahead decision for these patients?

Arun will take the call.

Thanks, Shankar. Yes. So based on the Phase I/II study outcome, our plan is to have a separate arm for the LCA because it's a different disease. So once we have the data, we will be engaging with the agency and following the agency's recommendation, we will initiate the trial accordingly.

Okay. Got it. And in terms of the Phase I/II data threshold, what would you consider favorable to advance into Phase III?

Primarily the safety and efficacy.

This concludes the Q&A portion. I will now turn the call back over to Chairman and CEO, Dr. Shankar Musunuri.

Thank you, operator. Our efforts in the first quarter of the year evidenced the importance of our gene therapy programs and the need to operate the business to ensure their success. We are opportunistic about Ocugen's cell therapy and vaccine platforms, knowing that these technologies have great therapeutic and financial potential and are pursuing partnerships to support our entire pipeline. We look forward to what this quarter and the rest of the year holds for the company, our people and the patients we serve. Tiffany?

Thanks, everyone. Bye.

Ladies and gentlemen, that concludes today's call. Thank you all for joining; you may now disconnect.
