A Study of BH-30643 in Subjects With Locally Advanced or Metastatic NSCLC Harboring EGFR and/or HER2 Mutations
Purpose
BH-30643-01 is a Phase 1/2, first-in-human, open label, dose escalation and expansion study in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) and/or human epidermal growth factor receptor (HER2) mutations. The study drug, BH-30643 capsules, will be self-administered by mouth twice daily in 21-day cycles. 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.

Inclusion Criteria
- ≥ 18 years or legal adult. - Pathologically confirmed diagnosis of locally advanced or metastatic NSCLC with EGFR (classical, atypical, exon20 insertion) or HER2 mutations in the kinase domain of exons 18, 19, 20, or 21.

Exclusion Criteria
- History of any concurrent malignancy within the previous 2 years. - Known other oncogenic driver alterations (eg, moderate or high MET amplification) or histological transformation (eg, to small cell carcinoma, etc.). - Unresolved toxicities from prior therapies. - Any significant and uncontrolled medical condition, such as infection. - History of interstitial lung disease from any cause - Clinically significant cardiovascular event within 6 months or significant history of major organ. - Actively receiving investigational therapy(ies) in another clinical study. *The above are a summary; other Exclusion Criteria details may apply.

Detailed Description
BH-30643 is a novel, orally available, reversible, mutant selective, macrocyclic OMNI-EGFR inhibitor that targets mutations in the EGFR kinase domain, including EGFR classical, atypical (also called uncommon or nonclassical), and ex20ins mutations, and a variety of EGFR resistant mutations (eg, ex19del/T790M, ex19del/C797S, ex19del/T790M/C797S, L858R/T790M, L858R/C797S, and L858R/T790M/C797S), as well as HER2 mutations including ex20ins mutations. In addition, BH-30643 has demonstrated good selectivity over wildtype EGFR and HER2. This 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.
