Official title
A Phase II Trial of Avelumab, A Fully Human Antibody That Targets Cells Expressing PD-L1, in Patients With Recurrent or Progressive Osteosarcoma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This clinical trial seeks to determine if avelumab will be effective in facilitating removal of all gross tumor in the event of a relapse of osteosarcoma in pediatric patients. Avelumab will be evaluated using dosing that has previously been determined in adult studies. Primary Objectives: * To estimate the response rate to 4 cycles of avelumab in patients with recurrent or progressive osteosarcoma. * To estimate the 16-week progression free survival of patients with recurrent or progressive osteosarcoma after treatment with avelumab. Secondary Objective: * To describe the toxicities associated with the administration of avelumab in patients with recurrent or progressive osteosarcoma. * To assess the quality of life of patients with recurrent or progressive osteosarcoma undergoing treatment with avelumab, and to explore relationships between clinical factors and patient-reported health-related quality of life (HRQOL) outcomes. Exploratory Objectives: * To explore factors associated with response in patients treated with avelumab after recurrent or progressive osteosarcoma (e.g. tumor PD-L1 expression). * To measure parameters of immune activation including subsets of peripheral blood mononuclear cells (PBMCs) and serum markers of immune activation. * To evaluate the role of T-cells in immune checkpoint blockade via measures of cell proliferation, co-inhibitory receptor expression on CD8 T cells, T cell repertoire, and epigenetic programming.
