A Phase 1b/2 Study of Atezolizumab in Combination with Thiopurine Therapy in Patients with Metastatic Solid Tumors and Intermediate Tumor Mutational Burden
Abstract Purpose: The TEMPLE study was a phase 1b/2 trial evaluating the safety, tolerability, and efficacy of atezolizumab combined with thiopurine therapy in patients with metastatic solid tumors, aim-ing to increase tumor mutational burden (TMB) through single-nucleotide mismatching and neoepitope generation. Patients and Methods: Phase 1b was an open-label, single-arm dose de-escalation trial conducted to determine the recommended phase 2 dose (RP2D) of 6-mercaptopurine and 6-thioguanine combined with atezolizu …
