Ocugen, Inc. Announces Dosing Completion of Subjects with Stargardt in Cohort 1 of Phase 1/2 Clinical Trial Evaluating the Safety and Efficacy of OCU410ST

MALVERN, Pa., Feb. 22, 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 dosing is complete in the first cohort of its Phase 1/2 GARDian clinical trial for OCU410ST (AAV5-hRORA)—a modifier gene therapy candidate being developed for Stargardt disease. Stargardt disease is an orphan blindness disease that affects approximately 35,000 people in the United States alone.

“This is an important clinical milestone for our first-in-class, potential one-time therapy for the treatment of Stargardt disease,” said Dr. Arun Upadhyay, Chief Scientific Officer and Head of R&D at Ocugen. “Although Stargardt is one of the most common inherited retinal diseases, there remains no treatment option to address this condition. OCU410ST provides hope to these patients who may eventually lose their vision.”

Up to 10 leading retinal surgery centers across the United States are participating in the GARDian clinical trial. In the first cohort, 3 subjects received 200L single subretinal administration of the low dose (3.75x10¹⁰ vg/mL) of OCU410ST.

“I am very pleased to participate in this study and to offer a novel modifier gene therapy option to my patients,” said Benjamin Bakall, MD, PhD, Director of Clinical Research at Associated Retina Consultants and Clinical Assistant Professor at the University of Arizona, College of Medicine—Phoenix. “Until now, we have not had any effective treatment that can prevent the vision loss in patients with Stargardt disease. Now, I believe that this approach can offer a new therapeutic option to address the disease itself.”

The GARDian clinical trial will assess the safety 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 (3.75×10E¹⁰ vg/mL), medium dose (7.5×10E¹⁰ vg/mL), and high dose (2.25×10E¹¹ 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.
