MALVERN, PA — In a significant advancement for retinitis pigmentosa (RP) treatment, Ocugen, Inc. (NASDAQ: OCGN) has received favorable scientific advice from the European Medicines Agency (EMA) regarding its pivotal Phase 3 liMeliGhT clinical trial for OCU400. The Committee for Medicinal Products for Human Use (CHMP) of the EMA reviewed and accepted the study design, endpoints, and planned statistical analysis for submission of a Marketing Authorization Application (MAA) in Europe.
This development follows the U.S. Food and Drug Administration’s (FDA) clearance of the Investigational New Drug (IND) amendment to initiate the Phase 3 trial, marking a crucial juncture for OCU400 as the first gene therapy to enter Phase 3 trials with a broad RP indication. RP, a group of rare genetic disorders that lead to progressive vision loss, has long presented a challenge in finding effective treatments due to its genetic diversity. Ocugen’s approach with OCU400, which has already demonstrated safety and tolerability in Phase 1/2 studies, offers a new horizon for patients with this severe condition.
The liMeliGhT study is set to enroll 150 participants primarily in the U.S., divided into two arms based on their genetic makeup related to RP—one arm for those with RHO gene mutations and the other for those with multiple gene mutations associated with RP. Participants will be randomized in a 2:1 ratio to either receive the treatment or be placed in an untreated control group.
Ocugen’s CEO, Dr. Shankar Musunuri, expressed gratitude towards the EMA for their support and collaboration, highlighting the potential of OCU400 to meet the urgent need for effective treatments in the RP patient community. The company’s gene-agnostic therapeutic strategy represents a novel approach in tackling the complexity of genetic diseases like RP, offering hope to patients who have had limited options until now.
The EMA’s positive opinion not only validates the promising data from earlier phases of OCU400’s development but also streamlines the pathway for Ocugen to bring this innovative treatment to the European market. This could significantly reduce the time and resources required to gain marketing authorization in the EU, a critical factor for biotech companies navigating the complex regulatory landscape.
For industry watchers, this development underscores the growing importance of gene therapies in addressing rare and genetically diverse diseases. Ocugen’s progress with OCU400 highlights the potential for such treatments to change the standard of care for conditions with high unmet medical needs. Furthermore, the company’s success in aligning its clinical trial design with regulatory expectations in both the U.S. and EU points to a strategic approach to global market access—a key consideration for investors and partners in the biopharmaceutical sector.
As Ocugen stays on track for its 2026 approval targets for both the Biologics License Application (BLA) in the U.S. and the MAA in the EU, the RP patient community and the broader field of genetic medicine watch closely. The successful development and approval of OCU400 could not only offer new hope to those affected by RP but also set a precedent for the future of gene therapy applications across a spectrum of genetic disorders.
