What this Trial Is About

This is a first-in-human (FIH), open label Phase 1/1b / Phase 2 study in patients with advanced metastatic solid tumors refractory to standard treatment. Phase 1 will identify potential optimal biologically relevant doses (OBRD) and the maximum tolerated dose (MTD) of MBRC-101 at one 1 or more dosing regimens. Phase 1b will evaluate the safety and preliminary clinical activity of MBRC-101 at potential OBRDs. Phase 1 and Phase 1b will both characterize single and multiple-dose PK profiles and evaluate incidence and persistence of anti-MBRC-101 Ab. Phase 2 will evaluate the efficacy of MBRC-101 at the RP2D from Phase1b.
