Overview
HS-10376 is an oral, highly selective, small molecular inhibitor of EGFR/HER2 Exon 20 insertion mutation. This study will evaluate the safety, tolerability, pharmacokinetics and clinical activity of HS-10376 in Chinese advanced Non-Small Cell Lung Cancer (NSCLC) patients.
Description
This is a phase 1/2, first-in-human, open-label, multicenter study of HS-10376, this study has two parts: phase 1 and phase 2. The phase 1 portion consists of dose escalation and dose expansion, which is aimed to assess the safety and tolerability of HS-10376 in subjects with advanced NSCLC and evaluate the preliminary efficacy of HS-10376. Phase 2 will be conducted to evaluate the efficacy of HS-10376 in subjects with locally advanced or metastatic NSCLC with a EGFR Exon 20 insertion mutation.
Eligibility
Inclusion Criteria:

- At least one measurable lesion in accordance with RECIST 1.1
- Eastern Cooperative Oncology Group (ECOG) performance status: 0~1
