New treatment option for Non-small Cell Lung Cancer
Official title Phase 1/2 Trial of S241656 in Selected RAS/MAPK Mutation- Positive Malignancies
ClinicalTrials.gov ID: NCT05786924
What this study is testing
What is S241656?
S241656 is an investigational medicine, given as a pill taken by mouth, being studied as a potential treatment for non-small cell lung cancer.
Also referred to as BDTX-4933.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- BDTX-4933-101 is a first-in-human, open-label, Phase 1/2 dose escalation, dose optimization and expansion study designed to evaluate the safety and tolerability of S241656 as monotherapy and in combination with other anti-cancer therapies in participants with selected advanced malignancies. The study population for the Dose Escalation part of the study comprises adults with recurrent advanced/metastatic non-small cell lung cancer (NSCLC), Gastrointestinal (GI) cancers, and other solid tumors harboring KRAS, HRAS, NRAS, BRAF, and/or CRAF (Rapidly Accelerated Fibrosarcoma (RAF1)) mutations or alterations.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
