Overview
This is a Phase I clinical study of HS-20108. The purpose of this study is to evaluate the safety, tolerability, PK and efficacy of intravenous HS-20108 in patients with advanced solid tumors.
Description
This is a multicenter, open-label Phase I clinical study to evaluate the safety, tolerability, PK and efficacy of intravenous HS-20108 in patients with advanced solid tumors. The study consists of Phase Ia (dose escalation) and Phase Ib (dose expansion). In Phase Ia, dose escalation in monotherapy and combination therapy will conduct to identify the maximum tolerated dose (MTD) in patients with advanced solid tumors. In Phase Ib, potential indications (such as small cell lung cancer or neuroendocrine carcinoma) will be selected for the early proof-of-concept study of HS-20108 at different doses in monotherapy and combination therapy based on the study data from Phase Ia, the translational medicine research data and R\&D progress in the field.
