Initial Clinical Data from INSPIRE DUCHENNE Trial of SGT-003

On February 18, 2025, Solid Biosciences Inc. (the “Company”) announced positive initial data from the Phase 1/2 INSPIRE DUCHENNE trial evaluating SGT-003, a next-generation gene therapy product candidate intended for the treatment of Duchenne muscular dystrophy (“Duchenne”). The INSPIRE DUCHENNE trial is a Phase 1/2 first-in-human, open-label, single-dose, multicenter trial designed to evaluate the safety, tolerability and efficacy of SGT-003 in pediatric patients with Duchenne at a dose of 1E14vg/kg. SGT-003 is administered as a one-time intravenous infusion. Interim 90-day biopsy data reported in the first three participants showed an average microdystrophin expression of 110%, as measured by western blot, and improvements in multiple biomarkers that are indicators of muscle health and resilience. The 90-day data reported of the data cutoff date of February 11, 2025 includes: microdystrophin expression, measures of restoration and activation of key elements of the dystrophin-associated protein complex, key muscle integrity biomarker evaluation, in each case, from the first three participants dosed in the INSPIRE DUCHENNE trial, and interim safety findings from the first six participants dosed in the INSPIRE DUCHENNE trial. The first three participants are two 5-year-old boys and one 7-year-old boy at the time of dosing. The second three participants are a 6-year-old boy and two 7-year-old boys at the time of dosing.

Securities Purchase Agreement On January 8, 2024, Solid Biosciences Inc., a Delaware corporation (the “Company”), entered into a securities purchase agreement (the “Securities Purchase Agreement”) with certain institutional accredited investors (the “Investors”), pursuant to which the Company agreed to issue and sell to the Investors in a private placement an aggregate of 16,973,103 shares of the Company’s common stock, par value $0.001 per share (the “Shares”), at a price of $5.53 per share, and, to one Investor in lieu of Shares, pre-funded warrants to purchase 2,712,478 shares of the Company’s common stock (the “Pre-Funded Warrants”), at a price of $5.529 per Pre-Funded Warrant (the “Private Placement”). The Private Placement is expected to close on or about January 11, 2024, subject to the satisfaction of certain customary closing conditions. The Company expects to receive aggregate gross proceeds from the Private Placement of approximately $108.9 million, before deducting placement agent fees and offering expenses, and aggregate net proceeds from the Private Placement of approximately $104.1 million, after deducting placement agent fees. Citigroup Global Markets Inc. and Cantor Fitzgerald & Co. acted as joint lead placement agents for the Private Placement.

The Private Placement includes new and existing investors, including Perceptive Advisors, Adage Capital Partners LP, Deerfield Management Company, Invus, Janus Henderson Investors, Vestal Point Capital, LP, Bain Capital Life Sciences, RA Capital Management and an undisclosed life sciences investor, among others. Pre-Funded Warrants Each Pre-Funded Warrant to be issued in the Private Placement will have an exercise price of $0.001 per share, will be exercisable immediately and will be exercisable until the Pre-Funded Warrant is exercised in full. Under the terms of the Pre-Funded Warrants, the Company may not effect the exercise of any such warrant, and a holder will not be entitled to exercise any portion of any such warrant, if, upon giving effect to such exercise, the aggregate number of shares of common stock beneficially owned by the holder (together with its affiliates, any other persons acting as a group together with the holder or any of the holder’s affiliates, and any other persons whose beneficial ownership of common stock would or could be aggregated with the holder’s for purposes of Section 13(d) or Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) would exceed 4.99% of the number of shares of common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determ
