As of December 28, 2022, all new REMS (Risk Evaluation and Mitigation Strategy) submissions and all REMS updates will be required to be submitted in SPL (Structured Product Labeling) format per the FDA. This is in compliance with the Final Guidance on REMS issued by FDA in late December 2020. This means that any current REMS registrations will not need to be submitted in SPL until they require updates. There are currently 62 active REMS—58 ETASU (Elements to Assure Safe Use) and 4 basic (non-ETASU.)
