Ocugen Announces Positive Data and Safety Monitoring Board Review and Initiation of Enrollment in Medium Dose for OCU410ST—a Modifier Gene Therapy—in GARDian Study for Stargardt Disease

• Established Low Dose as Safe and Tolerable Dose in Current OCU410ST Clinical Trial
• DSMB Determination to Proceed with Medium Dose Cohort Dosing
  

MALVERN, Pa., April 01, 2024 (GLOBE NEWSWIRE) -- Ocugen, Inc. (Ocugen or the Company) (NASDAQ: OCGN), a biotechnology company focused on discovering, developing, and commercializing novel gene and cell therapies and vaccines, today announced that the Data Safety and Monitoring Board (DSMB) for the OCU410ST clinical trial recently convened and approved to proceed dosing with the medium dose of OCU410ST in the dose-escalation phase of the study.

Three patients with Stargardt disease were dosed in the Phase 1/2 clinical trial to date. An additional three patients will be dosed with the medium dose (Cohort 2) and three patients with the high dose (Cohort 3) of OCU410ST in the dose-escalation phase.

“The DSMB has recommended moving forward to medium dose for dosing subjects with Stargardt disease,” said Dr. Peter Chang, MD, FACS, DSMB Chair for the OCU410ST clinical trial. “No serious adverse events (SAEs) related to OCU410ST have been reported to date. I believe that this marks a critical next step towards determining the optimal dosing regimen for OCU410ST.”

“We are pleased to see the continued favorable safety and tolerability profile exhibited by OCU410ST, allowing us to evaluate a higher dose in patients with Stargardt retinal dystrophy,” said Huma Qamar, M.D., MPH, Chief Medical Officer of Ocugen. “We recognize the high unmet medical need for Stargardt patients, as there are no current FDA-approved therapies for the indication, and we look forward to sharing the interim safety data from our Phase 1 trial in the second quarter of 2024.”

The GARDian clinical trial will assess the safety and efficacy of unilateral subretinal administration of OCU410ST in subjects with Stargardt disease and will be conducted in two phases. Phase 1 is a multicenter, open-label, dose ranging study consisting of three dose levels [low dose (3.75×10¹⁰ vg/mL), medium dose (7.5×10¹⁰ vg/mL), and high dose (2.25×10¹¹ vg/mL)]. Phase 2 is a randomized, outcome accessor-blinded, dose-expansion study in which adult and pediatric subjects will be randomized in a 1:1:1 ratio to either one of two OCU410ST dose groups or to an untreated. The Company will continue to provide clinical updates.
