A Study of MHB048C in Patients With Advanced Solid Tumors

This first-in-human clinical trial of MHB048C comprises two parts: a dose escalation phase and a dose 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 MHB048C 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 dose expansion phase. This phase is an open-label, multicenter, multi-cohort study designed to further evaluate the safety and efficacy of MHB048C monotherapy in patients with mCRPC or other types of advanced solid tumors.
