Overview
Brief Summary
This is a Phase 1, open-label study to evaluate the safety and the efficacy of inetetamab in combination with pyrotinib in patients in HER2 mutant or amplified patients with advanced non-small cell lung cancer
Detailed Description
This study is a multi-center, opening, dose-escalating phase Ib clinical trial. The aim of the study is to evaluate the safety and efficacy of inetetamab combined with pyrotinib in the treatment of patients in HER2 mutant or amplified patients with advanced non-small cell lung cancer .Primary endpoint of the study is dose-limiting toxicity dosage and safety. Efficacy indicators including objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS) are as Secondary endpoint. Up to 48 NSCLC patients will be enrolled the treatment will be performed 3+3 dose-escalation phase I design and expanded to phase II study. A treatment cycle lasts 3 weeks,and the combined medication will be continued until the occurrence of toxicity intolerance,disease progression,or death,or patients refuse to continue participating in this clinical study,or the investigators determine that the medication must be terminated. The recommended initial consistent dose of inetetamab in groups 1-3 are 8 mg/kg, intravenous infusion for more than 90 minutes, and the maintenance dose is 6 mg/kg. The oral doses of pyrotinib in groups 1-3 were 240 mg, 320 mg, or 400 mg, respectively. Safety evaluation will be taken according to hematological toxicity, non-hematological toxicity and National Cancer Institute (NCI)-Common Terminology Criteria (CTC) For Adverse Events (AE) V5.0.
