A Phase 1/1B Study of ST-01156, a Small Molecule RBM39 Degrader, in Patients With Advanced Solid Malignancies

Description

This Phase 1/1b study is evaluating the safety, tolerability, and preliminary anticancer activity of ST-01156 in participants with advanced solid malignancies. The study will be conducted in 2 parts. Part 1 (Dose Escalation) will assess the safety, tolerability, pharmacokinetics (PK) and preliminary anticancer activity of SD-01156 in participants with advanced solid malignancies, many of whom have a biological rationale to be targeted with an inhibitor of RBM39. Part 1 will also seek to determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of ST-01156.
