Ocugen Announces Data and Safety Monitoring Board Approves Enrollment in High Dose Cohort 3 in GARDian Study for Stargardt Disease
Globe Newswire 21-Jun-2024 7:00 AM
• Established Medium Dose as Safe and Tolerable Dose in Current OCU410ST Clinical Trial • DSMB Determination to Proceed with High Dose Cohort Dosing
MALVERN, Pa., June 21, 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 and Safety Monitoring Board (DSMB) for the OCU410ST GARDian clinical trial recently convened and approved to proceed with dosing the high dose of OCU410ST in the dose-escalation phase of the study. OCU410ST (AAV5-hRORA) is a modifier gene therapy candidate being developed for Stargardt disease. Stargardt disease affects approximately 100,000 people in the U.S. and Europe combined.
Six patients with Stargardt disease have been dosed in the Phase 1/2 clinical trial to date in the low dose cohort and medium dose cohort. An additional three patients will be dosed with the high dose in cohort 3.
"The DSMB has recommended moving forward to dose subsequent subjects with Stargardt disease at the targeted high dose," said Dr. Peter Y. Chang, MD, FACS, DSMB Chair for the OCU410ST clinical trial. "No serious adverse events (SAEs) related to OCU410ST have been reported to date. This is an important next step in the clinical progress for OCU410ST and encouraging for patients living with this most common form of inherited retinal disease."
"We are delighted to report a second positive DSMB recommendation for the treatment of Stargardt disease and build upon the favorable safety and tolerability profile exhibited by OCU410ST," said Huma Qamar, M.D., MPH, Chief Medical Officer of Ocugen. "We recognize the high unmet medical need for Stargardt patients as there is no approved product. We are enthusiastic about OCU410ST as a potential one-time treatment for life with a single sub-retinal injection. We look forward to sharing a clinical trial update later this year."
The Phase 1/2 GARDian clinical trial will include up to 42 subjects—30 adults and 12 children with Stargardt disease—who exhibit mild to moderate disease symptoms and will assess the safety of unilateral subretinal administration of OCU410ST. The clinical trial is being conducted in two phases. Phase 1 is a multicenter, open-label, dose-ranging/dose-escalation 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 enrolled in a 1:1:1 ratio to randomize subjects into two different treatment groups at varying dose levels, or a control (untreated group), allowing for a comprehensive assessment of the treatment's efficacy across different dosages.
Currently, patients with Stargardt disease have no FDA-approved therapeutic options. Ocugen is dedicated to providing a gene-agnostic treatment approach for patients living with inherited retinal diseases and is encouraged that the Phase 1/2 GARDian trial for OCU410ST remains on track.
About Stargardt Disease
Stargardt disease is a genetic eye disorder that causes retinal degeneration and vision loss. Stargardt disease is the most common form of inherited macular degeneration. The progressive vision loss associated with Stargardt disease is caused by the degeneration of photoreceptor cells in the central portion of the retina called the macula.
Decreased central vision due to loss of photoreceptors in the macula is the hallmark of Stargardt disease. Some peripheral vision is usually preserved. Stargardt disease typically develops during childhood or adolescence, but the age of onset and rate of progression can vary. The retinal pigment epithelium (RPE), a layer of cells supporting photoreceptors, is also affected in people with Stargardt disease.
About OCU410ST
OCU410ST utilizes an AAV delivery platform for the retinal delivery of the RORA (RAR Related Orphan Receptor A) gene. It represents Ocugen's modifier gene therapy approach, which is based on Nuclear Hormone Receptor (NHR) RORA that regulates pathway links to Stargardt disease such as lipofuscin formation, oxidative stress, complement formation, inflammation, and cell survival networks.
