NCT03006848
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.
NCT05403450
The primary purpose of the study is to assess safety, and to identify the recommended phase 2 dose (RP2D) of tolinapant in combination with oral decitabine/cedazuridine in Phase 1 and to assess preliminary efficacy as determined by overall response rate (ORR) in Phase 2. As no safe and tolerable dosing for the combination of tolinapant and decitabine/cedazuridine was identified based on protocol defined criteria, Sponsor decided to halt recruitment and to not conduct Phase 2 of the study.
