Safety and Efficacy of HCB101 in Combination With Multiple Agents in Patients With Advanced Solid Tumors
Summary
This is a non-randomized, open-label, dose-escalation, and dose-expansion Phase Ib/IIa study to evaluate the safety, tolerability, PK, PD, and preliminary antitumor activity of HCB101 administered in combination with standard or approved anticancer therapies in subjects with advanced solid tumors. The trial includes a Part-I (Phase Ib) of the dose-escalation phase and a Part-II (Phase IIa) of the dose-expansion phase. Part-I: Dose-escalation phase (Phase Ib): Part I uses a standard 3+3 dose-escalation design to characterize safety and tolerability and to determine the maximum tolerated dose (MTD) and/or recommended Phase II dose (RP2D) of HCB101 when administered in combination regimens. The study includes 14 planned cohorts (Cohorts 1-9, including sub-cohorts 3a-3d and 6a-6c). Part-II: Dose-expansion phase (Phase IIa) Based on safety, tolerability, PK/PD, and emerging antitumor activity observed in Part-I (Phase Ib), selected dose levels, tumor types, and combination regimens will be further investigated in Part-II (Phase IIa).
