Why are we doing this research?
BRIEF SUMMARY:
This is a multicenter, 1:1 randomized Phase III study of intradermal autologous Vigil immunotherapy (1.0 x 10e6 cells/injection; minimum of 4 to a maximum of 12 administrations) in combination with irinotecan and temozolomide in subjects with metastatic Ewing's sarcoma Family of Tumors (ESFT) refractory/intolerant or recurrent to 1 prior line of chemotherapy. Participants undergoing a standard surgical procedure (e.g., tumor biopsy or palliative resection) may have tumor tissue harvested for manufacture of the investigational product, Vigil.
DETAILED DESCRIPTION:
Participants will be managed in an outpatient setting. Hematologic function, liver enzymes, renal function and electrolytes will be monitored. Blood for immune function analyses including IFNγ-ELISPOT analysis of cytotoxic T cell activation in response to autologous tumor antigens will be collected at tissue procurement, post-procurement screening and Day 1 (prior to chemotherapy administration) at Cycles 2, 4, and 6, end of treatment (EOT), 3 months after EOT, and every 6 months thereafter. Blood for ctDNA analysis will be collected at tissue procurement, prior to chemotherapy administration at baseline and on Day 1 prior to chemotherapy administration at Cycles 2, 3, 4, and 6, and EOT.
