CHARLESTOWN, Mass. — Solid Biosciences Inc. (Nasdaq: SLDB) (the “Company” or “Solid”), a life sciences company developing precision genetic medicines for neuromuscular and cardiac diseases, today announced that U.S. Food and Drug Administration (FDA) has granted Orphan Drug designation to SGT-212 for the treatment of Friedreich’s ataxia (FA). Additionally, earlier today, the Company reported that the first participant has been dosed in FALCON, a Phase 1b, first-in-human clinical trial evaluating SGT-212 for the treatment of FA.
“Receiving Orphan Drug, Fast Track and Rare Pediatric Disease designations underscores the significant unmet need the FA community faces and recognizes the therapeutic potential of SGT-212’s novel, dual-route administration,” said Jessie Hanrahan, Ph.D., Chief Regulatory & Preclinical Operations Officer of Solid Biosciences. “We anticipate that the ability to leverage these regulatory designations will help streamline and potentially accelerate SGT-212’s development path, and we look forward to working closely with regulators to bring a potential new treatment option to the FA community.”
SGT-212 is a first-in-class investigational gene therapy for the treatment of FA that employs a dual-route administration designed to target the neurologic, cardiac and systemic manifestations of the disease, which are key drivers of morbidity and mortality seen in FA. SGT-212 is delivered through a precise, stereotactic, MRI-guided intradentate nuclei (IDN) infusion to the cerebellar dentate nuclei followed by an intravenous (IV) infusion, with the goal of restoring therapeutic levels of frataxin.
About Orphan Drug Designation
The U.S. Food and Drug Administration (FDA) grants Orphan Drug designation (ODD) to investigational therapies intended for the treatment, diagnosis or prevention of rare diseases or conditions affecting fewer than 200,000 people in the United States. ODD provides certain development incentives, including tax credits for qualified clinical testing, waiver of FDA application fees and seven years of market exclusivity upon approval. These benefits are designed to encourage innovation and to potentially accelerate the availability of treatments for patients with serious underserved conditions.
About the FALCON Trial
FALCON is a first-in-human, open-label, multi-center Phase 1b clinical trial designed to evaluate the safety and tolerability of SGT-212 in participants aged 18-40 who have been diagnosed with FA and cardiac hypertrophy. FALCON is being conducted in the United States.
About SGT-212
SGT-212 is a recombinant AAV-based gene replacement therapy for Friedreich’s ataxia (FA) designed to deliver full-length human frataxin (FXN) via a dual route of administration: intradentate nucleus (IDN) infusion, using an FDA-approved neurosurgical device in a stereotactic, precision MRI-guided technique, followed by an intravenous (IV) infusion, with the intent to increase therapeutic FXN levels in the cerebellar dentate nuclei, cardiomyocytes and other systemic tissues. Targeted delivery to the dentate nuclei will be confirmed in real time via MRI. Restoration of FXN levels is expected to repair the underlying mitochondrial dysfunction in neurons and cardiomyocytes to address neurologic, cardiac and systemic manifestations of the disease.
About Friedreich’s Ataxia (FA)
FA is an inherited, life-threatening, degenerative multisystem disease caused by variants in the frataxin gene that disrupt production of the frataxin protein, a mitochondrial iron-binding protein involved in essential cellular processes, including energy production. FA is known to cause progressive nervous system damage, movement problems, and cardiac dysfunction, with cardiac complications identified as the primary cause of death. FA impacts approximately 5,000 people in the United States and 15,000 in Europe. There are currently no treatments that provide a cure or halt disease progression.
About Solid Biosciences
Solid Biosciences is a precision genetic medicine company focused on advancing a portfolio of gene therapy candidates targeting rare neuromuscular and cardiac diseases, including SGT-003 for Duchenne muscular dystrophy (Duchenne), SGT-212 for Friedreich’s ataxia (FA), SGT-501 for catecholaminergic polymorphic ventricular tachycardia (CPVT), SGT-601 for TNNT2-mediated dilated cardiomyopathy and additional fatal, genetic neuromuscular and cardiac diseases. The Company is also focused on developing innovative libraries of genetic regulators and other enabling technologies with promising potential to significantly impact gene therapy delivery cross-industry. Solid is advancing its diverse pipeline and delivery platform in the pursuit of uniting experts in science, technology, disease management, and care. Patient-focused and founded by those directly impacted by Duchenne, Solid’s mission is to improve the daily lives of patients living with devastating rare diseases.
