Clinical Trials

Multiple clinical trials evaluate FHD-286 (camibirstat) across Phase 1 and Phase 2 studies for hematologic malignancies and solid tumors. Industry sponsor Foghorn Therapeutics Inc. initiated Phase 1 trials in advanced hematologic malignancies—including acute myeloid leukemia, myelodysplastic syndromes, and chronic myelomonocytic leukemia (active, not recruiting)—and a terminated trial in metastatic uveal melanoma. Additionally, academic institutions lead a recruiting Phase 1 combination trial with low-dose decitabine and venetoclax at Montefiore Medical Center and a Dana-Farber Cancer Institute–sponsored Phase 2 study in POU2F3-positive small cell lung cancer that is not yet recruiting.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Camibirstat (FHD-286) selectively inhibits the BRG1 and BRM ATPase subunits of the BAF chromatin remodeling complex, disrupting ATP-dependent nucleosome positioning and transcriptional activation required for oncogenic gene expression programs. This targeted disruption suppresses aberrant chromatin accessibility and halts neoplastic cell proliferation, demonstrating clinical relevance in BAF-dependent malignancies such as acute myeloid leukemia and small cell lung cancer under clinical evaluation.

Appendix RUO and cGMP Quality Standards

Quality Dimension RUO (Research Use Only) cGMP (Current Good Manufacturing Practice)
Clinical Applicability Prohibited in human clinical trials or medical diagnostics. Mandatory for human clinical trials (Phase I–III) and therapies.
Regulatory Status Non-regulated grade; exempt from drug manufacturing laws. Legally enforced by health authorities (e.g., FDA, EMA, NMPA).
Facility Environment Unclassified analytical or research laboratories. Validated Cleanrooms (ISO Class 5–8) with continuous monitoring.
Quality Control Basic purity and activity testing. Rigorous safety release testing (Sterility, Endotoxin, Mycoplasma).
Process Validation Basic equipment calibration; no process validation required. Full qualification (IQ/OQ/PQ) and complete batch records.
Quality Assurance Vendor self-declared without required formal QMS. Mandatory QA/QC unit, Change Control, CAPA, and vendor audits.
Regulatory Impact High risk of IND rejection if used as a critical raw material. Required for IND/NDA filings, supported by Drug Master Files (DMF).
