• Positive SGT-003 Clinical Data

  Interim Phase 1/2 INSPIRE DUCHENNE trial for SGT-003 showed robust mean microdystrophin expression (60% at Day 90, 91% at Day 360 by western blot) and functional improvements, including properly localized beta-sarcoglycan and nNOS activity, with a mean 44% reduction in eMHC-positive fibers at Day 90. The therapy was generally well tolerated in 41 participants, with one Grade 3 immune-mediated myositis serious adverse event that resolved with steroid treatment.

• Advancement to Phase 3

  SGT-003 is progressing to a Phase 3 IMPACT DUCHENNE trial, with participant screening underway and first dosing anticipated in April 2026. The company is also planning meetings with the FDA in the first half of 2026 to discuss a potential accelerated approval pathway.

• Significant Capital Raise

  The company completed a private placement in March 2026, issuing 14,973,257 shares of common stock and pre-funded warrants to purchase 27,807,482 shares, generating approximately $226.4 million in net proceeds.

• Extended Cash Runway

  With the net proceeds from the March 2026 private placement, the company believes its cash, cash equivalents, and available-for-sale securities will be sufficient to fund operating expenses and capital requirements into the first half of 2028.

Solid Biosciences' annual report for fiscal year 2025 provides a comprehensive update that significantly de-risks the company's financial position and validates its lead gene therapy program. The successful $226.4 million private placement, completed in March 2026, is a substantial capital infusion that extends the company's cash runway into the first half of 2028, addressing a critical funding need for a clinical-stage biotech. Concurrently, the positive interim Phase 1/2 clinical data for SGT-003 in Duchenne muscular dystrophy, demonstrating robust microdystrophin expression and functional improvements, is a strong indicator of therapeutic potential and supports its progression to a pivotal Phase 3 trial. This combination of strong clinical validation and secured long-term financing is highly impactful for the company's future trajectory.
