Summary

This is an expanded access study involving an investigational product named Vigil. Vigil is considered immunotherapy. Patients who participated in another clinical trial sponsored by Gradalis, and had Vigil made from their tumor tissue removed from a standard operation, however failed the criteria to enroll in the other clinical trial to receive Vigil are eligible to screen for this expanded access trial to receive the Vigil made from their cancer cells. In this study, eligible participants will receive intradermal (under the skin) injections of Vigil, once every 4 weeks (28 days) for 1-12 doses, depending on the number of doses that was made from the cancer cells and if the participant is clinically stable. During the treatment portion of the study, in addition to receiving Vigil injections, participants will also have a physical exam, blood collection for routine and research tests, and assessment of medications, adverse events, and performance status information will be collected. Radiological tumor assessments will be performed every 3 months from Cycle 1. Once treatment ends, participants will continue to be seen in the clinic every 3 months for similar assessments until disease progression occurs. After disease progression, participants will be contacted by phone 4 times a year to determine post study treatment and survival status information.

Detailed description

This is an Expanded Access trial of Vigil (bi-shRNAfurin and GMCSF Augmented Autologous Tumor Cell Immunotherapy) in Advanced Solid Tumors. Approximately 40 subjects who had tissue procured and Vigil manufactured but fail manufacturing release criteria under a previous Gradalis protocol are considered for this study. Eligible participants will receive a minimum of 1 and a maximum of 12 doses of Vigil intradermal injections every 4 weeks as monotherapy. Participants will be managed in an outpatient setting. Hematologic function, liver enzymes, renal function and electrolytes will be monitored. Blood for immune function analyses in response to autologous tumor antigens will be collected at screening, Day 1 (prior to Vigil administration) at Cycles 2, 4, and 6, end of treatment (EOT); 3 months after EOT, and every 6 months thereafter for those in response follow up. For subjects with Ewing's sarcoma, blood for ctDNA analysis will be collected at screening, on Day 1 prior to Vigil administration at Cycles 2, 3, 4, and 6, and EOT.

Interventions

Type	Name	Description
BIOLOGICAL	Vigil	Vigil is composed of autologous tumor cells harvested from the patient at the time of initial de-bulking surgery which are then transfected extracorporeally, with a plasmid encoding for the gene for GM-CSF, an immune-stimulatory cytokine, and a bifunctional, short hairpin RNA which specifically knocks down the expression of furin, the critical convertase responsible for production of the two TGβ isoforms (TGFβ-1 and TGFβ-2).
