EVRY, France--( BUSINESS WIRE )-- Atamyo Therapeutics a clinical-stage biotechnology company focused on the development of new generation gene therapies targeting muscular dystrophies and cardiomyopathies, today announced that the U.S. Food & Drug Administration (FDA) has cleared its Investigational New Drug (IND) application for ATA-200 to proceed in a Phase 1b/2b clinical trial. ATA-200 is a one-time gene therapy for the treatment of γ-sarcoglycan related limb-girdle muscular dystrophy Type 2C/R5 (LGMD2C/R5), a serious and debilitating condition that affects children and leads to loss of ambulation before adulthood. The multicenter Phase1b open-label dose escalation study ( NCT05973630 ) will evaluate safety, pharmacodynamics, efficacy, and immunogenicity in children receiving intravenous ATA-200, a single-dose Adeno-Associated Virus (AAV) vector carrying the human γ-sarcoglycan transgene. The deployment in the US of Atamyo’s clinical trial of ATA-200 is funded by The Dion Foundation for Children with Rare Diseases . This study has already received regulatory clearance in France and Italy. “This IND clearance in an important step to bring ATA-200 to US children suffering from this highly debilitating LGMD-2C/R5 disease,” said Sophie Olivier, MD, Chief Medical Officer of Atamyo. “We are proud to be the first treatment for LGMD-2C/R5 to enter into clinical development in the US and we are committed to opening the first US center before year-end,” added Stéphane Degove, Atamyo’s Chief Executive Officer. In addition, Atamyo announced the US FDA has awarded Orphan Drug Designation for ATA-200. Orphan Drug Designations by the FDA grants seven years of market exclusivity in the US. This Orphan Drug Designation for ATA-200 was granted a few weeks after ATA-200 received Rare Pediatric Disease Designation by the FDA. LGMD-2C/R5 is a rare genetic disease caused by mutations in the gene that produces γ-sarcoglycan, a transmembrane protein that is involved in the connection between muscle fibers and their environment. It affects an estimated 2,000 people in Europe and in the US. In the classical form, symptoms appear in early childhood and patients suffer from progressive muscular weakness leading to loss of ambulation before adulthood. Cardiac involvement, typically presenting as dilated cardiomyopathy, is reported in approximately half of patients and will eventually impact life expectancy. There is no curative treatment. The management of LGMD-2C/R5 is solely supportive. ATA-200, the gene therapy for LGMD-2C/R5, delivers a normal copy of the gene for production of γ-sarcoglycan. In preclinical mice models, ATA-200 demonstrated its tolerability and capability to correct symptoms and biomarkers of the pathology. Atamyo plans to initiate enrolling patients for this clinical trial in the 4 th quarter of 2024. The therapy is based on the research of Atamyo Chief Scientific Officer Isabelle Richard, Ph.D., Research Director at CNRS who heads the Progressive Muscular Dystrophies Laboratory at Genethon. About Atamyo Therapeutics Atamyo Therapeutics is a clinical-stage biopharma focused on the development of a new generation of effective and safe gene therapies for neuromuscular diseases. A spin-off of gene therapy pioneer Genethon, Atamyo leverages unique expertise in AAV-based gene therapy and muscular dystrophies from the Progressive Muscular Dystrophies Laboratory at Genethon. Atamyo’s most advanced programs address different forms of limb-girdle muscular dystrophies (LGMD), with two clinical-stage programs targeting respectively LGMD-R9 and LGMD-R5. The name of the company is derived from two words: Celtic Atao which means “Always” or “Forever” and Myo which is the Greek root for muscle. Atamyo conveys the spirit of its commitment to improve the life of patients affected by neuromuscular diseases with life-long efficient treatments. For more information visit www.atamyo.com

- Study exceeded target enrollment, with an expected topline data readout from the interim analysis expected in 2025 - BridgeBio believes there is an opportunity to pursue Accelerated Approval in the U.S. for BBP-418 in LGMD2I/R9 based on a potential biomarker surrogate endpoint of glycosylated alpha-dystroglycan (αDG) at time of the interim analysis - If successful, BBP-418 could be the first approved therapy for individuals living with LGMD2I/R9 in the U.S. - Enrollment completion announced on 10th annual LGMD Awareness Day, a collaborative yearly effort on September 30th to globally raise awareness of individuals living with LGMD PALO ALTO, Calif., Sept. 30, 2024 (GLOBE NEWSWIRE) -- BridgeBio Pharma, Inc. (Nasdaq: BBIO) (“BridgeBio” or the “Company”), a commercial-stage biopharmaceutical company focused on genetic diseases, announced, on LGMD Awareness Day, the completion of enrollment of FORTIFY, the Company’s Phase 3 registrational study of BBP-418 in individuals with LGMD2I/R9. FORTIFY is a randomized, double-blind, placebo-controlled Phase 3 study evaluating the safety and efficacy of BBP-418, an investigational oral therapy in development for the treatment of individuals living with LGMD2I/R9. The study includes a planned interim analysis at 12 months focused on assessing glycosylated αDG as a surrogate endpoint to potentially support Accelerated Approval. The primary endpoint, to be evaluated at 36 months, is the North Star Assessment (NSAD) for limb-girdle type muscular dystrophies and is designed to provide confirmatory clinical data supporting the efficacy of BBP-418. More information about the Phase 3 clinical trial of BBP-418 (NCT05775848) can be found here on clinicaltrials.gov. A topline data readout from the interim analysis is expected in 2025. “Living with a progressive muscle wasting condition like LGMD2I/R9 means that individuals are continually losing the ability to perform daily activities independently and relying on friends and family to support them as they experience a continued decline in strength and health. For patients with LGMD2I/R9, there are currently no approved treatment options, but the promise seen in the rapid enrollment of this clinical trial provides hope for patients and their families that this may change in the future,” said Kelly Brazzo, CEO of CureLGMD2i Foundation. “Completing rapid enrollment of FORTIFY is an important milestone and underscores the need for a therapeutic option for patients,” said Douglas Sproule, M.D., M.Sc., Chief Medical Officer of ML Bio Solutions, a BridgeBio company developing BBP-418 for LGMD2I/R9. “Based on multiple encouraging discussions with the FDA, we believe there is an opportunity to pursue Accelerated Approval in the U.S. for BBP-418 in LGMD2I/R9 based on a potential surrogate endpoint biomarker of glycosylated αDG at time of the interim analysis. If successful, BBP-418 could be the first approved disease-modifying therapy for individuals living with LGMD2I/R9 in the U.S. We’re immensely grateful to the patients, their families, and the trial site investigators participating in our study and look forward to sharing pivotal data with the community.” 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). Consistent with the Rare Pediatric Designation from the FDA, if BBP-418 is approved, BridgeBio may qualify for a Priority Review Voucher. 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 respiratory 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 respiratory failure by 30 years of age in nearly all cases.
