Summary

This is a first-in-human, open-label, multicenter Phase I study of MHB118C in patients with advanced solid tumors. The study was designed to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of MHB118C monotherapy.

Detailed description

This first-in-human clinical trial of MHB118C comprises two parts: a dose escalation phase and indication expansion phase. The dose escalation phase is an open-label, multicenter study including dose escalation and PK expansion cohorts. The primary objectives are to evaluate the safety, tolerability, pharmacokinetics, and preliminary antitumor activity of MHB118C in patients with advanced solid tumors, and to determine the maximum tolerated dose (MTD). In this phase, additional patients may be enrolled in the PK expansion part at dose levels that have completed DLT (dose-limiting toxicity) evaluation. Based on the safety, PK, and preliminary efficacy data from the completed DLT-evaluated dose levels, the sponsor will initiate the indication expansion phase. This phase is an open-label, multicenter, multi-cohort study designed to further evaluate the safety and efficacy of MHB118C monotherapy in patients with specific types of advanced solid tumors.
