OncoMatch/Clinical Trials/NCT06706076

A Study of BH-30643 in Subjects With Locally Advanced or Metastatic NSCLC Harboring EGFR and/or HER2 Mutations

Is NCT06706076 recruiting? Yes, currently enrolling (May 2026). This Phase 1/2 trial studies multiple treatments including BH-30643 and BH-30643 for nsclc (advanced non-small cell lung cancer).

Phase 1/2RecruitingBlossomHill TherapeuticsNCT06706076Data as of May 2026

Treatment: BH-30643 · BH-30643This Phase1/2, open label, multicenter study will assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics and preliminary anti-tumor activity of BH-30643 in patients with NSCLC having EGFR and/or HER2 mutations. Phase 1 will determine the recommended Phase 2 dose (RP2D) and, if applicable, the maximum tolerated dose (MTD) of BH-30643. Phase 2 will further evaluate the antitumor efficacy and safety in specified cohorts determined by EGFR/HER2 mutation subtypes and/or treatment history at the RP2D, as well as the population PK.
