Complete Response Letter NDA 505b1 218223 (Mar 8, 2024)
This document from the U.S. Food and Drug Administration (FDA) outlines significant deficiencies in New Drug Application (NDA) 218223 for GA Depot as a treatment for relapsing forms of multiple sclerosis (RMS). The FDA found the Phase 3 trial (Study Mapi GA Depot Phase III – 001) did not provide interpretable or persuasive efficacy findings, failed to establish an adequate scientific bridge to Copaxone, and exhibited numerous issues with trial design, data quality, and reliability. Furthermore, the submitted safety data were deemed inadequate, and the study raised new safety concerns, including severe injection site reactions and systemic injection-related reactions, suggesting important differences from Copaxone.
