CHARLESTOWN, Mass., May 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 reported financial results for the first quarter ended March 31, 2026, and provided a business update.
Bo Cumbo, President and CEO of Solid Biosciences, stated: "The beginning of 2026 has seen Solid make meaningful strides as we continue to execute across our pipeline and platform development efforts. In Duchenne, we dosed the first participant in our Phase 3 IMPACT DUCHENNE clinical trial for SGT-003 and received Orphan drug designation from the European Commission, representing important milestones in the program's global advancement. We also continue to enroll and dose participants in the Phase 1/2 INSPIRE DUCHENNE clinical trial, which has maintained a consistent and encouraging safety and tolerability profile.
"As we progress through the year, we look forward to ongoing engagement with the FDA, focusing on our thoughtful approach to generating rigorous, well-controlled clinical data through our integrated, multi-country, multi-trial development program. We recognize the significant unmet need in Duchenne and see the potential for our novel therapy to offer a differentiated treatment option for families living with this unrelenting disease.
"In parallel, we are working closely with the UK Medicines and Healthcare products Regulatory Agency (MHRA) under our ILAP Innovation Passport and recently received a positive opinion from the European Medicines Agency $(EMA)$ on our Pediatric Investigation Plan, reflecting our efforts to inform potential development and regulatory pathways outside of the United States. We continue to build the organizational and geographic foundations to support future global development and have made the decision to establish dedicated ex-U.S. leadership with the planned addition of a Head of Europe.
"Beyond Duchenne, we have now dosed two participants in the Phase 1b FALCON clinical trial of our Friedreich's ataxia gene therapy program, SGT-212, which has been well tolerated by both participants. While still early, we are encouraged by initial clinical observations and remain focused on advancing the program thoughtfully as data emerge. Across our company, we continue to execute our plan and advance our programs with the fiscal discipline and operational rapidity required to deliver meaningful outcomes to patients and our shareholders," Mr. Cumbo concluded.

About SGT-003
SGT-003 is an investigational gene therapy containing a novel microdystrophin construct and a proprietary, next-generation capsid, POLARIS-101(TM) (formerly known as AAV-SLB101), which was rationally designed to target integrin receptors, and has shown enhanced cardiac and skeletal muscle transduction with decreased liver targeting in data from the Phase 1/2 INSPIRE DUCHENNE clinical trial and in nonclinical studies. SGT-003's microdystrophin construct uniquely includes the R16/17 domains, which localize nNOS to the muscle. Nonclinical studies have shown that nNOS can improve blood flow to the muscle thereby reducing muscle breakdown from ischemia and muscle fatigue. Together, these design features suggest that SGT-003 could be a potential best-in-class investigational gene therapy for the treatment of Duchenne.
About the SGT-003 Development Program
The SGT-003 clinical development program consists of two multinational clinical trials -- the Phase 1/2 INSPIRE DUCHENNE trial and the Phase 3 IMPACT DUCHENNE trial -- which together were designed to generate a comprehensive data package to support potential global regulatory authorizations.
INSPIRE DUCHENNE is a first-in-human, open-label, single-dose, multicenter Phase 1/2 clinical trial evaluating the safety, tolerability and efficacy of a single dose of SGT-003 in pediatric participants with a genetically confirmed Duchenne diagnosis. The trial is being conducted at clinical sites in the United States, Canada, the United Kingdom and Italy.
IMPACT DUCHENNE is a Phase 3 placebo-controlled, randomized, double-blind clinical trial evaluating the efficacy of a single dose of SGT-003 in ambulatory participants with a genetically confirmed Duchenne diagnosis. Clinical trial sites are currently active in Australia and Canada and additional clinical site activations in the UK and US are expected in the second half of 2026, with sites in the EU anticipated to follow, subject to regulatory clearances.
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 the FALCON Clinical 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. FALCON is being conducted in the United States.
