简要总结
HS-20093 is a fully 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 and pharmacokinetics of HS-20093 in Chinese patients with metastasis Castration Resistant Prostate Cancer.
This is a phase 2, open-label, multi-center study to evaluate the efficacy, safety, tolerability and pharmacokinetic (PK) of HS-20093 as a monotherapy in subjects with metastasis castration resistant prostate cancers (mCRPC) and other solid tumors.
详细描述
This is a phase 2, open-label, multi-center study consisting of two parts: Phase 2a and 2b.
Phase 2a: The study will be conducted in the following two cohorts: Cohort 1: Patients with metastasis castration resistant prostate cancers who have progressed on or intolerant to standard therapies. Cohort 2: Other patients with advanced solid tumor if they have progressed on or intolerant to available standard therapies, or no standard or available curative therapy exists. All subjects will receive 8 mg/kg of HS-20093.
Phase 2b: The study will be conducted in patients with metastasis castration resistant prostate cancers who have progressed on or intolerant to standard therapies. Subjects will receive 8 mg/kg of HS-20093.
All patients will be carefully followed for adverse events during the study treatment and for 90 days after the last dose of HS-20093. Subjects will be permitted to continue therapy with assessments for progression if the product is well tolerated and sustained clinical benefit exists.
