Detailed Description

This is a multicenter, open-label, Phase I clinical study of HS-20117 to evaluate the safety, tolerability, PK, immunogenicity and efficacy in participants with advanced solid tumors. The study consists of phase Ia (dose escalation) and phase Ib (dose expansion). The dose-escalation study will be performed to evaluate the safety, tolerability, PK profile, immunogenicity, and efficacy of HS-20117 in participants with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutations. The subsequent dose-expansion study will be performed to evaluate the efficacy of HS-20117 in participants with locally advanced or metastatic NSCLC who have progressed after prior platinum-based chemotherapy or are intolerant to platinum-based chemotherapy with EGFR exon 20 insertion mutations, and to explore the efficacy of HS-20117 in participants with other advanced solid tumors.

Time Frame: Cycle 1 (28 days)
MAD is defined as follows: a) based on PK data, it is anticipated that at this dose level, the dose-exposure plateau has been reached, b) based on existing safety data, it is judged that dose escalation following this dose level will have a large safety risk or subject intolerance, or c) based on the PK-PD model, it suggested that the optimal target concentration of safety and efficacy has been explored.
