Ocugen, Inc. announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) reviewed the study design, endpoints and planned statistical analysis of the ongoing pivotal confirmatory OCU410ST Phase 2/3 GARDian3 clinical trial for Stargardt disease and provided acceptability of a single U.S.-based trial for submission of a Marketing Authorization Application (MAA). EEMA provided this opinion based on safety and tolerability that OCU410ST demonstrated in the Phase 1 GARDian trial, including 48% slower lesion growth and statistically significant (p=0.031) and clinically meaningful improvement of nearly 2-line/9- letter gain in best corrected visual acuity (BCVA) at 12-month follow-up in evaluable treated eyes compared to untreated eyes. The Phase 2/3 study will enroll 51 participants diagnosed with Stargardt disease.

Of these, 34 will receive a one-time subretinal injection of OCU410ST (200 mL at a concentration of 1.5 x 1011 vector genomes/mL) in the eye with poorer visual acuity, while 17 will be assigned to an untreated control group. The unique adaptive design of this trial includes a masked interim analysis of 24 subjects in the study (16 in treatment group and 8 in control group) at 8 months.
