Foghorn Therapeutics ends Eli Lilly partnership and cuts workforce, shares tumble

Foghorn Therapeutics announced that it and Eli Lilly will discontinue the development of the lead oncology candidate FHD-909 after a Phase 1 trial failed to meet efficacy criteria. The company also terminated a separate SMARCA2 degrader program and plans to reduce its staff by roughly 40%, leaving about 65 employees. The board expects the restructuring to generate about $2.3 million of one‑time charges and to push the cash runway into the second half of 2029, with cash of $167.6 million reported on June 30 2026.

The termination of the Lilly collaboration removed a major source of future revenue and caused the stock to fall sharply, trading down more than 30% on the day of the announcement. The workforce reduction and cash‑runway extension indicate a shift to a wholly proprietary pipeline, which may affect investors' valuation of the company’s near‑term prospects.
