A Study of HS-20124 in Patients with Advanced Solid Tumors

Официальное название

A Phase I, Open-label, Multicenter Study to Evaluate Safety, Tolerability, Pharmacokinetics, and Efficacy of HS-20124 in Patients with Advanced Solid Tumors

Обзор

HS-20124 is a novel DAR-8 antibody-drug conjugate （ADC） targeting CDH6. In preclinical studies, it inhibited tumor cell growth expressing CDH6 in vitro and in vivo. The first-in-human trial is conducted to assess the maximum tolerated dose (MTD) and dose limiting toxicity (DLT), to evaluate the pharmacokinetics, safety and preliminary anti-tumor activity of HS-20124 in Patients With Advanced Solid Tumors.

Подробное описание

This is a Phase 1a/1b open-label, multicenter study with dose escalation and dose expansion cohorts to evaluate the safety, tolerability, PK and preliminary efficacy of HS-20124 in patients with advanced solid tumors.

The dose escalation will utilize rolling-6 design. In phase of dose expansion, preliminary efficacy will be evaluated in planned expansion cohorts that include patients with specific advanced solid tumor types.

Вмешательства

• Препарат HS-20124 (Phase Ia：Dose escalation )
  Participants will receive HS-20124 in 21 day dosing cycles. Participants will continue treatment until the end of the study in the absence of unacceptable toxicities and unequivocal disease progression.
• Препарат HS-20124 (Phase Ib: Dose expansion)
  Participants will receive HS-20124 in 21 day dosing cycles. Participants will continue treatment until the end of the study in the absence of unacceptable toxicities and unequivocal disease progression.

Первичные конечные точки

• Objective tumor response for target lesions will be assessed by imaging/measurement compared with the overall tumor burden at baseline (Day -28 to -1). ORR is evaluated by the number of participants with best overall response of complete response (CR) an [Срок оценки: 3 weeks after initiation of treatment]
• Ⅰb (Dose-Expansion Stage): Objective response rate (ORR) determined by investigators according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 [Срок оценки: From the first dose up to PD or withdrawal from study, whichever came first.]

Вторичные конечные точки (8)

• Incidence and severity of treatment-emergent adverse events [Срок оценки: From the first dose through 30 days post end of treatment]
• Observed maximum plasma concentration (Cmax) [Срок оценки: At the end of Cycle 1 (each cycle is 21 days)]
• Time to reach maximum plasma concentration (Tmax) [Срок оценки: At the end of Cycle 1 (each cycle is 21 days)]
• Terminal half-life (T1/2) [Срок оценки: At the end of Cycle 1 (each cycle is 21 days)]
• Percentage of participants with antibodies to HS-20124 in serum [Срок оценки: At the end of Cycle 1 (each cycle is 21 days)]
• ORR determined by investigators according to RECIST 1.1 (dose-escalation stage) [Срок оценки: during the intervention]
• Duration of response (DOR) determined by investigators according to RECIST 1.1 [Срок оценки: during the intervention]
• Progression-free survival (PFS) determined by investigators according to RECIST 1.1 [Срок оценки: From the randomization/first dose up to PD or death, whichever came first]
