Avutometinib (INN; codenamed RO-5126766, CH-5126766, CKI-27, R-7304, RG-7304, and VS-6766 at various stages of its development) is an inhibitor of Ras-Raf-MEK-ERK signaling being developed as a potential treatment for cancer.

It was discovered by Chugai Pharmaceutical Co. (a subsidiary of Roche) through derivatization of a hit compound identified by high-throughput screening.^[1] It was licensed by Verastem Oncology in 2020 for clinical trials.^[2]^[3]

The co-packaged medication avutometinib/defactinib was approved for medical use in the United States in May 2025.^[4]^[5]
