Initial data from the Phase 1b FALCON trial expected in H2 2026, subject to participant enrollment
CHARLESTOWN, Mass., Jan. 12, 2026 (GLOBE NEWSWIRE) -- 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 the first participant has been dosed in FALCON, the Company’s Phase 1b, first-in-human clinical trial evaluating SGT-212, its investigational gene therapy for the treatment of Friedreich’s ataxia (FA).
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.
Gabriel Brooks, M.D., Chief Medical Officer of Solid Biosciences, commented: “Dosing our first participant in this first-in-human Friedreich’s ataxia trial is a momentous achievement for the FA community and for Solid Biosciences. We believe our novel, real-time, MRI-guided stereotactic delivery approach is one that truly embodies the promise of precision genetic medicine. We are ecstatic to report that intra-procedural MRI-imaging confirmed intradentate nuclei targeting and coverage that surpassed our expectations as well as thresholds we believe are necessary for a potential treatment effect. While these are early, single-participant observations, they strengthen our confidence in our targeted strategy and underscore our commitment to advancing paradigm-transforming treatments. We look forward to sharing preliminary safety insights in the coming months and expect to share an initial data update in the second half of 2026, subject to participant enrollment.”
Bo Cumbo, President & CEO of Solid Biosciences, commented: “Initiating dosing in the FALCON trial represents the culmination of years of dedicated work towards moving the needle for the FA community. By aiming to precisely target the key structures responsible for neurologic morbidity and cardiac manifestations, we intend to address both quality-of-life and mortality drivers in this devastating disease, a key differentiation of SGT-212 when compared to potential alternatives. The dual-route administration strategy employed by SGT-212 exemplifies Solid’s mission to be bold in our vision, audacious in our science and steadfast in our commitment to bringing potentially life-changing medicines to patients.”
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.
