FHD-909 FDA Regulatory Timeline and Events
FHD-909 is a drug developed by Foghorn Therapeutics for the following indication: A BRM (SMARCA2) selective inhibitor.
This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- FHD-909
- Announced Date:
- April 21, 2026
- Indication:
- A BRM (SMARCA2) selective inhibitor
Announcement
Foghorn® Therapeutics Inc. today presented new preclinical data for Selective SMARCA2 inhibitor FHD-909 showing complete and durable tumor regression together with anti-tumor immune memory following combination treatment with an anti-PD-1 antibody in preclinical syngeneic mouse models.
AI Summary
Foghorn Therapeutics reported preclinical results for its selective SMARCA2 inhibitor FHD-909 (LY4050784). In syngeneic mouse tumor models, FHD-909 given with an anti‑PD‑1 antibody produced complete and durable tumor regressions. Tumors did not return after dosing stopped, and attempts to re‑implant fresh tumor cells on the opposite flank of cured animals failed, indicating the mice had developed anti‑tumor immune memory. The data show the combination both cleared tumors and induced a lasting immune response in these models.
These findings support further evaluation of SMARCA2 inhibition combined with PD‑1 blockade as a cancer therapy. The results are preclinical and will need confirmation in clinical trials before any conclusions about safety or benefit in patients can be drawn.

- FHD-909
- Announced Date:
- April 28, 2025
- Indication:
- A BRM (SMARCA2) selective inhibitor
Announcement
Foghorn® Therapeutics announced new preclinical data for potential first-in-class medicines, including FHD-909, a SMARCA2 (BRM) selective inhibitor, and the Selective CBP degrader program at the 2025 American Association for Cancer Research (AACR) Annual Meeting.
AI Summary
Foghorn Therapeutics announced promising new preclinical data at the 2025 AACR Annual Meeting. The company is focusing on FHD-909, a first-in-class, orally available SMARCA2 (BRM) selective inhibitor currently in a Phase 1 trial for patients with SMARCA4-mutated cancers, primarily targeting non-small cell lung cancer (NSCLC). Early results show that FHD-909, when used in combination with pembrolizumab, KRAS inhibitors, and standard chemotherapy, exhibits strong synergistic anti-tumor effects, encouraging further clinical exploration.
In addition, the Selective CBP degrader program has demonstrated potential in preclinical studies, particularly in ER+ breast cancer models. These data suggest that the new combination strategies could offer effective treatment options for patients with hard-to-treat cancers. Foghorn Therapeutics is committed to advancing these innovative approaches as part of its mission to develop novel medicines for serious diseases.

- Announced Date:
- December 16, 2024
- Indication:
- Metastatic Uveal Melanoma (mUM)
Announcement
Foghorn® Therapeutics announced today that it has made the decision to discontinue the independent development of FHD-286 in combination with decitabine in patients with relapsed and/or refractory acute myeloid leukemia (AML).
AI Summary
Foghorn® Therapeutics announced that it will discontinue the independent development of FHD-286 combined with decitabine for treating patients with relapsed or refractory acute myeloid leukemia (AML). Although the Phase 1 trial showed some clinical responses based on standard response criteria, the overall response rate did not meet the company’s threshold to move forward on its own. Foghorn is now considering strategic partnerships and investigator sponsored trials (ISTs) to further explore FHD-286.
In addition, the company will focus its investment on its proprietary pipeline and its collaboration with Lilly, notably on the clinical-stage selective SMARCA2 (BRM) inhibitor FHD-909. With a cash balance of $267.4 million as of September 30, 2024, Foghorn has sufficient funds to support its operations until 2027, while it continues to explore new opportunities in oncology.
