Clinical and regulatory milestones include SGT-003 dosing (15 participants dosed as of August 12, 2025) with reported initial biopsy expression of microdystrophin averaging 110%, SGT-212 IND clearance (Dec 2024), and SGT-501 IND clearance and Health Canada CTA approval (July 2025). The February 2025 offering generated approximately $188.0 million of net proceeds. The company expects its cash, cash equivalents and securities to fund operations into the first half of 2027.
Form 4 highlights: On 07/06/2025, Solid Biosciences Inc. (SLDB) director Ian F. Smith acquired 4,573 common shares through the mandatory conversion (Code M) of previously granted restricted stock units (RSUs). The RSUs, issued on 01/06/2025, vest in four equal quarterly tranches and convert to common stock on a 1-for-1 basis. Following the transaction, Smith now directly owns 122,119 common shares and retains 9,146 unvested RSUs. The RSUs will accelerate in full if the Executive Chair Agreement terminates early or upon a change in control of the company. No shares were sold, suggesting continued insider exposure to SLDB’s equity. The filing was signed on 07/08/2025.
Solid Biosciences (NASDAQ:SLDB) filed a routine Form 4 disclosing that director Georgia Keresty received a stock-option grant covering 77,500 shares on 06/12/2025 at an exercise price of $4.58 per share.
The option vests in full on the earlier of the one-year anniversary of the grant or immediately prior to the next annual shareholder meeting, and accelerates upon certain change-in-control events. It expires on 06/12/2035. No open-market purchases or sales of common stock were reported, and Keresty’s beneficial ownership now reflects only the newly granted option, held directly.
