BridgeBio Pharma Accelerates on Path to Potential Accelerated Approval with BBP-418 for Rare Muscular Dystrophy
In a pivotal development, BridgeBio Pharma, Inc. (“BridgeBio”), a trailblazer in the biopharmaceutical realm with a focus on genetically-influenced diseases, has announced a significant milestone in its ongoing Phase 3 FORTIFY clinical study. The company has successfully exceeded its enrollment target for an interim analysis in the treatment of individuals afflicted with Limb-girdle Muscular Dystrophy Type 2I/R9 (LGMD2I/R9) using BBP-418, signaling promising advancements in the quest for a groundbreaking therapy.
The eagerly anticipated top-line results from this interim analysis are set to be unveiled in 2025. The FORTIFY study, which stands as a double-blind, placebo-controlled, randomized trial, is pivotal in evaluating the efficacy and safety of BBP-418. This investigational oral therapy harbors the potential to markedly enhance the lives of those grappling with LGMD2I/R9.
FORTIFY’s design includes a 12-month interim analysis centered on assessing glycosylated alpha-dystroglycan (αDG) as a surrogate endpoint—an innovative move aimed at supporting an Accelerated Approval pathway. The ultimate endpoint, to be assessed at 36 months, relies on the North Star Assessment (NSAD) for limb-girdle type muscular dystrophies, intending to furnish confirmatory clinical data.
Distinguished by productive dialogues with the U.S. Food and Drug Administration (FDA) that took place in 2024, these discussions have significantly bolstered BridgeBio’s strategy to pursue Accelerated Approval for BBP-418. They have conveyed a nod towards the solidity of using glycosylated αDG levels as a surrogate endpoint, enhancing the momentum towards a viable therapeutic offering.
Moreover, the FDA’s endorsement of BBP-418’s Rare Pediatric Disease Designation (RPDD) underscores the gravity of LGMD2I/R9 as a rare, yet serious disease predominantly affecting children. This recognition not only mirrors the urgent need to address the unmet medical requirements within this domain but also aligns BridgeBio with an opportunity to secure a Priority Review Voucher, catalyzing the advancement of other therapies within its pipeline.
About LGMD2I/R9: LGMD2I/R9 emerges from mutations within the fukutin-related protein (FKRP) gene, disrupting the glycosylation of αDG—a vital muscle cell stabilizer. Its clinical trajectory typically manifests as a debilitating skeletal myopathy, progressing towards significant cardiac and respiratory complications. Such grim prospects underline the dire necessity for innovative therapeutic interventions.
