Clinical Trial Summary

HS-20093 is a humanized IgG1 antibody-drug conjugate (ADC) which specifically binds to B7-H3, a target wildly expressed on solid tumor cells. The objectives of this study are to investigate the anti-tumor activity, safety, pharmacokinetics and immunogenicity of HS-20093 in Chinese advanced esophageal carcinoma and other solid tumor patients.

Description:

This is an open-label, multi-center phase 2 study in Chinese adult participants with recurrent, locally advanced or metastatic esophageal carcinoma or other advanced solid tumors, which is designed to investigate the efficacy, safety, pharmacokinetics and immunogenicity of HS-20093. This study will consist of two parts: phase IIa and phase IIb.

Part 1 (phase IIa) will conducted in participants with relapsed, locally advanced or metastatic esophageal carcinoma and other advanced solid tumor. Subjects will receive one dose levels of HS-20093 intravenously every 3 weeks.

Part 2 (phase IIb) will enroll participants with relapsed, locally advanced or metastatic esophageal squamous cell carcinoma. One dose levels of HS-20093 will be administered as an intravenous (IV) infusion every 3 weeks.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective response rate (ORR) determined by investigators according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.	ORR was defined as the percentage of participants who achieved a best overall response (BOR) of confirmed Complete Response (CR) or Partial Response (PR), assessed by investigators based on RECIST version 1.1[Confirmed CR/PR assessment require at least one repeat (=4 weeks)].	From the first dose up to disease progression(PD)or withdrawal from study,whichever comes first,assessed up to 24 months.
Secondary	DOR assessed by RECIST 1.1 criteria	DOR was defined as the period from the first occurrence of CR or PR to PD or death from any cause. If no PD or death after CR/PR, the cut-off date of progression-free survival (PFS) would be used [Confirmed CR/PR assessment require at least one repeat (=4 weeks)	From the first dose up to PD or death, whichever came first, assessed up to 24 months.
Secondary	Disease Control Rate (DCR) assessed by RECIST 1.1 criteria	DCR was evaluated by the number of participants with best overall response of CR, PR and stable disease (SD) [Confirmed CR/PR assessment require at least one repeat (=4 weeks); SD shall be assessed at least 5 weeks after the first dose.	From the first dose up to PD or withdrawal from study, whichever came first, assessed up to 24 months.
Secondary	PFS assessed by RECIST 1.1 criteria	PFS was defined as the time from first dose or random assignment (if any) to PD or death from any cause	From the first dose up to PD or death,whichever came first, assessed up to 24 months.
Secondary	Overall survival (OS)	OS was defined as the time from the first dose or random assignment (if any) to death from any cause	From the first dose up to PD or death,whichever came first, assessed up to 24 months.
Secondary	Incidence and severity of adverse events	AE assessed by investigator exclusively related to subject's underlying disease or medical condition [graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE), Version 5.0]. Any untoward medical occurrence in a clinical study participant, whether or not considered related to the medicinal product. Incidence and severity of AEs are assessed according to vital signs, laboratory variables, physical examination, electrocardiogram, etc	From the first dose until 90 days after the last dose
Secondary	Characterize the pharmacokinetic parameters of HS-20093	Characterize the pharmacokinetic parameters of HS-20093	Cycle 1 Day 1 up to 90 days after the last dose
Secondary	Assess the incidence of anti-drug antibodies (ADAs)	Serum samples were collected for the determination of anti-drug antibody (ADA) at designated time points	Cycle 1 Day 1 up to 90 days after the last dose
