- Comprehensive submission includes interim Phase 3 FORTIFY data demonstrating BBP-418’s rapid, consistent treatment effect and favorable safety profile, with statistically significant and clinically meaningful improvements in ambulation and pulmonary function - Based on ongoing discussions with the FDA, BridgeBio anticipates approval with a U.S. launch anticipated in late 2026/early 2027 - If approved, BBP-418 has the potential to become the first and only therapy for individuals living with LGMD2I/R9 and may represent the first approved treatment for any form of LGMD PALO ALTO, Calif., March 30, 2026 (GLOBE NEWSWIRE) -- BridgeBio Pharma, Inc. (Nasdaq: BBIO) (“BridgeBio” or the “Company”), a biopharmaceutical company focused on developing medicines for genetic conditions, today announced the submission of its New Drug Application (NDA) to the FDA for oral BBP-418 for the treatment of individuals living with limb-girdle muscular dystrophy type 2I/R9 (LGMD2I/R9). “This NDA submission brings us one step closer to delivering the first approved therapy to individuals and families affected by LGMD2I/R9, a severe, progressive neuromuscular disease,” said Christine Siu, Chief Executive Officer of BridgeBio Neuromuscular. “This achievement not only reflects the strength of the data, but also our dedicated focus on addressing the urgency of a community that has long been waiting for meaningful treatment options. We are committed to working closely with the FDA to make this potential disease-modifying therapy available as quickly as possible.” FORTIFY, the Phase 3 clinical trial of BBP-418, successfully met all pre-specified primary and secondary endpoints of its 12-month interim analysis. The topline results can be found here . Additional positive results demonstrating the rapid and consistent treatment effect and favorable safety pro BBP-418 were presented earlier this month at the 2026 MDA Clinical and Scientific Conference in a late-breaking oral presentation, which can be found here . BridgeBio anticipates a U.S. launch following FDA approval in late 2026/early 2027. If successful, BBP-418 would be the first and only approved therapy for individuals living with LGMD2I/R9, potentially representing the first approval of a therapy for any form of LGMD. The Company is also engaging regulatory agencies to identify an expedited path to approval for BBP-418 in Europe. BBP-418 has previously received Orphan Drug, Fast Track, and Rare Pediatric Disease Designations from the FDA and Orphan Drug Designation from the European Medicines Agency (EMA). With Fast Track designation and the potential for BBP-418 to address unmet need in LGMD2I/R9, the NDA for BBP-418 may be eligible for Priority Review. Consistent with Rare Pediatric Designation from the FDA, if BBP-418 is approved, BridgeBio may qualify for a Priority Review Voucher. The Company intends to initiate clinical studies of BBP-418 in LGMD2I/R9 for individuals less than 12 years of age and in LGMD2M/2U in the near future. About Limb-Girdle Muscular Dystrophy Type 2I/R9 (LGMD2I/R9) LGMD2I/R9 is a monogenic autosomal recessive disease caused by partial loss of function mutations in the fukutin-related protein (FKRP) gene, and FKRP mutations impair glycosylation of alpha-dystroglycan (αDG), a protein associated with stabilizing muscle cells. Clinical manifestations typically present as a skeletal myopathy affecting the lower and then upper limbs, which is commonly later accompanied by pulmonary muscle and cardiac muscle involvement. Individuals who harbor a homozygous L276I genotype typically develop disease manifestations during late childhood with progression to loss of independent ambulation (25%), assisted ventilation (10%), and cardiomyopathy (30%) in adulthood. Cardiomyopathy is progressive, with an annual loss of 0.4% of left ventricular ejection fraction (LVEF). Individuals with other FKRP genotypes typically have an earlier childhood onset with a more severe clinical course, rapid loss of mobility by 20 years of age, more frequent cardiac involvement (60%), and eventual pulmonary decline by 30 years of age in nearly all cases. About BridgeBio BridgeBio exists to develop transformative medicines for genetic conditions. Millions of people worldwide living with genetic conditions lack treatment options, often because drug development for small patient populations can be commercially challenging. We aim to bridge the gap between advancements in genetic science and meaningful medicines for underserved patient populations. Our decentralized, hub-and-spoke model is designed for speed, precision, and scalability. Autonomous and empowered teams focus on individual conditions, while a central hub provides the clinical, regulatory, and commercial capabilities needed to bring innovation to market.
