VITAS: Atezolizumab in Combination With Chemotherapy for Pediatric Relapsed/Refractory Solid Tumors: An Open-label, Phase II, Single-arm, Multi-center Trial
University of Texas Southwestern Medical Center
Summary
This trial is a multi-center, non-randomized, open-label Phase I/II study evaluating the feasibility and efficacy of vincristine, irinotecan, temozolomide, and atezolizumab in children with relapsed/refractory solid tumors.
Description
In this study, we will test the combination of atezolizumab with chemotherapy for relapsed solid tumors in childhood. The combination of vincristine, irinotecan, temozolomide, and atezolizumab has not been tested. Thus, the trial will have two sequential cohorts: (1) a feasibility cohort, and (2) a rhabdomyosarcoma (RMS) efficacy cohort. In the first cohort, we will determine the feasibility of administering vincristine, irinotecan, temozolomide, and atezolizumab simultaneously in children with relapsed or refractory solid tumors, regardless of histology or PD-L1 status. We will accrue 6 patie…
