Clinical Trial Summary

This study is an open-label, multicenter, first-in-human, Phase I, dose escalation study to evaluate the safety, tolerability, PK, and preliminary anti-tumor activity of JSKN003 in subjects with advanced inoperable or metastatic solid malignant tumors that are expected to be HER2 expression.

Clinical Trial Description

The dose escalation study will utilize single patient accelerated dose titration for the first two dose levels, 1.0 and 2.1 mg/kg, followed by dose cohorts 4.2, 5.2, 6.3, 7.3, and 8.4 mg/kg which will all be enrolled and monitored using the Bayesian optimal interval design, aimed at determining the MTD, RDE/RP2D of JSKN003. The dose-escalation of 9.4 mg/kg and 10.5 mg/kg should be determined per discussion between Safety Monitoring Committee and sponsor if deemed necessary, the SMC had the right of deciding to dose-escalate at other dose levels . Moreover, the SMC is also responsible for deciding the MTD and the recommended dose level for dose-expansion study. Enrolled patients will be sequentially assigned to the planned dose levels as required by the protocol and treated with JSKN003 IV Q3W to observe the occurrence of treatment related AEs and dose limiting toxicities. The DLT observation period is 21 days from administration of the first dose of JSKN003. The study will use a modified ADT design and BOIN design for dosing cohort management to determine the MTD and RDE/RP2D. The starting dose of JSKN003 is 1.0 mg/kg, followed by 2.1, 4.2, 5.3, 6.3, 7.3, 8.4, 9.4 and 10.5 mg/kg. The investigational product will be administered on Day 1 every 3 weeks via intravenous infusion, and the first cycle of JSKN003 treatment is for DLT evaluation. ;
