A Study of BDTX-4933 in Patients With BRAF and Select RAS/MAPK Mutation-Positive Cancers

BDTX-4933-101 is a first-in-human, open-label, Phase 1 dose escalation and multiple expansion cohort study designed to evaluate the safety and antitumor activity of BDTX-4933. The study population comprises adults with recurrent advanced/metastatic cancers harboring BRAF (Class I, II, and III), KRAS (other than G12C such as G12D, G12V), or NRAS mutations including non-small cell lung cancer (NSCLC), melanoma, histiocytic neoplasms, thyroid cancer, colorectal cancer, and other solid tumor cancers with or without brain metastases. All patients will self-administer BDTX-4933 orally in 28-day cycles until disease progression, toxicity, withdrawal of consent, or termination of the study.
