CHARLESTOWN, Mass., May 15, 2025 (GLOBE NEWSWIRE) — Solid Biosciences Inc. (Nasdaq: SLDB) (the “Company” or “Solid”), a life sciences company developing precision, next generation, genetic medicines for neuromuscular and cardiac diseases, today reported financial results for the first quarter ended March 31, 2025, and provided a business update.
Bo Cumbo, President and CEO of Solid, commented: “The positive initial three patient, 90-day data in the INSPIRE DUCHENNE trial of SGT-003, our next-generation, investigational gene therapy to treat Duchenne muscular dystrophy, were a milestone in the development of a meaningful treatment candidate for this terrible disease. With the initial data demonstrating robust microdystrophin expression and improvements across biomarkers of muscle integrity and, excitingly, encouraging biomarkers of cardiac and liver health, we continue to dose participants as we prepare to engage with the FDA later this year on the potential for accelerated pathways.
“To our patient communities, we know that safety is a critical factor in choosing any medical therapy. SGT-003, utilizing our proprietary, rationally designed capsid, AAV-SLB101, contains the lowest dose of any Duchenne gene therapy currently marketed or in clinical development, and to date, has demonstrated an encouraging safety and tolerability profile. We look forward to the 28th Annual Meeting of the American Society of Gene and Cell Therapy (ASGCT) where, on Saturday, we will provide an interim safety update from the INSPIRE DUCHENNE trial during our late-breaking oral presentation.
“As an organization, we are intensely focused on driving innovation and advancing the C> field with the aspiration to make gene therapies safer, more effective, and truly accessible. These efforts originate with our differentiated and thoughtfully designed neuromuscular and cardiac therapeutic pipeline and expand to the development and broad out-licensing of next-generation delivery technologies, beginning with AAV-SLB101. We look forward to executing across these objectives over the coming quarters to drive meaningful value for all of our stakeholders,” Mr. Cumbo concluded.
Company Updates
Neuromuscular Pipeline
SGT-003 for Duchenne Muscular Dystrophy (Duchenne)
- As announced on February 18, 2025, the Company reported positive initial clinical data from the first three participants dosed in the Phase 1/2 INSPIRE DUCHENNE trial.
- SGT-003 has been well tolerated in all participants dosed to date, with no treatment emergent serious adverse events (SAEs) or AEs of acute liver injury observed.
- The INSPIRE DUCHENNE trial continues dosing participants across multiple cohorts, and the Company expects to dose approximately 20 total participants by year-end.
- The INSPIRE DUCHENNE trial now has eight active sites in the U.S., Canada and Italy, with additional sites expected to be activated by year-end.
- The Company plans to meet with the FDA later this year to share safety and efficacy results from additional treated participants in the INSPIRE DUCHENNE study and to discuss accelerated regulatory pathways. The Company expects the meeting to occur in the fourth quarter of 2025.
SGT-212 for Friedreich’s Ataxia (FA)
- As announced on January 7, 2025, the FDA has cleared the IND for SGT-212 for the treatment of FA. SGT-212 is the first gene therapy candidate for FA to utilize a dual route of administration that was designed to promote restoration of therapeutic levels of the frataxin protein to address neurologic, cardiac and systemic clinical manifestations of FA.
- The Company expects to initiate a first-in-human, open-label, Phase 1b clinical trial of SGT-212 in the second half of 2025. The trial is expected to enroll non-ambulatory and ambulatory adult participants living with FA across up to three cohorts and is designed to evaluate the safety and tolerability of systemic and bilateral IDN administration of SGT-212.
Cardiac Pipeline
SGT-501 for Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT)
- IND-enabling Good Laboratory Practice (GLP) toxicology studies of SGT-501 in non-human primates were completed in the first quarter of 2025.
- The Company anticipates submitting an IND for SGT-501 for the treatment of CPVT in 1H 2025.
Platform Technologies – Capsids & Other
Capsids & Promoters
- The Company is building multiple cardiac and neuromuscular next-generation capsid and promoter libraries with final capsid selection from the first cardiac capsid library anticipated in the fourth quarter of 2025.
- AAV-SLB101 is the Company’s proprietary capsid used in SGT-003, which in the initial three participants dosed in the INSPIRE DUCHENNE study demonstrated rapid and robust levels of vector transduction, microdystrophin expression, and reduced liver targeting.
- Solid currently has partnership agreements with 19 academic labs, institutions and corporations for the use of AAV-SLB101, with additional partnerships expected to be executed over the coming quarters.
First Quarter 2025 Financial Highlights
- Cash Position: Solid had $306.9 million in cash, cash equivalents, and available-for-sale securities as of March 31, 2025, compared to $148.9 million as of December 31, 2024. The Company expects that its cash, cash equivalents, and available-for-sale securities as of March 31, 2025, will enable it to fund its operational runway into the first half of 2027.
- Research and Development (R&D) Expenses: R&D expenses for the first quarter of 2025 were $30.9 million, compared to $18.9 million for the first quarter of 2024. The increase of $12.0 million was primarily due to a $7.4 million increase in costs for SGT-003 primarily related to manufacturing, regulatory, and clinical costs, a $1.9 million increase in personnel-related expenses, a $1.3 million increase in other development program expenses primarily due to manufacturing costs, a $0.8 million increase in costs for SGT-212 primarily related to regulatory and clinical costs, and a $0.7 million increase in costs for SGT-501 primarily related to research, regulatory, and clinical costs.
- General and Administrative (G&A) Expenses: G&A expenses for the first quarter of 2025 were $9.1 million, compared to $8.0 million for the first quarter of 2024. The increase of $1.1 million was primarily due to a $1.7 million increase in personnel-related costs, partially offset by a $0.4 million decrease in other G&A expenses.
- Net Loss: Net loss for the first quarter of 2025 was $39.3 million, compared to $24.3 million for the first quarter of 2024.
