A Phase 1-2 Study of ST101 in Patients With Advanced Solid Tumors

NCT04478279

Purpose of the Study

ST101-101 is an open-label, two-part, phase 1-2 dose-finding study designed to determine the safety, tolerability, PK, PD, and proof-of-concept efficacy of ST101 administered IV in patients with advanced solid tumors. The study consists of two phases: a phase 1 dose escalation/regimen exploration phase and a phase 2 expansion phase.

Program Overview


ST101, a first-in-class antagonist of C/EBPβ, is currently being evaluated in the Phase 2 portion of an ongoing Phase 1-2 clinical study in patients with advanced unresectable and metastatic solid tumors (NCT04478279). In the ongoing Phase 2 dose expansion rGBM cohort (n=30), ST101 weekly administration resulted in a 30% Disease Control Rate (DCR) with 1 Partial Response (PR) and 8 patients with Stable Disease (SD), with a 6-month median duration of SD. In the ongoing surgical window of opportunity sub-study, ST101 is being evaluated as a monotherapy in rGBM and in combination with radiation and temozolomide in newly diagnosed GBM (ndGBM).

ST101 has been granted Fast Track designation for rGBM from the U.S. FDA and Orphan Drug designations for glioma from the U.S. FDA and the European Commission.
