A Risk Evaluation and Mitigation Strategy (REMS) is not proposed as the risks associated with LUXTURNA can be managed through routine measures. The proposed risk management plan includes: 1. Pharmacovigilance Plan: Routine and enhanced pharmacovigilance to monitor for known risks (e.g., endophthalmitis, cataract, increased IOP) and unexpected adverse events. 2. Risk Minimization Activities: a. Prescribing Information: The PI will communicate the risks associated with the subretinal administration procedure and LUXTURNA to healthcare providers. b. Surgical Training Program: Spark Therapeutics will implement a mandatory training program for surgeons on the proper preparation and subretinal administration of LUXTURNA to mitigate procedural risks. c. Pharmacy/Handling Training: Informational materials will be provided to hospital pharmacies regarding the specific storage, handling, and preparation requirements for a gene therapy product.
