Spots Global Cancer Trial Database for Pilot Study of Durvalumab and Vigil in Advanced Women's Cancers

Study Description

Brief Summary: In this study, the researchers want to learn more about Vigil and durvalumab in advanced women's cancers: 1) how much of Vigil in combination with durvalumab (MEDI4736) can be given with an acceptable level of side effects, 2) the effects of Vigil and durvalumab in combination (good and bad), 3) if Vigil will cause changes in cancer cells that may help durvalumab attack the cancer, and 4) whether or not Vigil and durvalumab will slow your cancer or stop your cancer from getting worse. Combining Vigil with durvalumab will allow the former to induce (or increase) the infiltration of activated T cells into tumors, and in addition, to enhance PD-L1 (programmed cell death ligand 1) expression. Consequently, the response rate of historically low or un-responsive cancer will be increased with the combination of Vigil and anti PD-L1.

Detailed Description: This is an open label pilot study to evaluate the safety, tolerability, and efficacy of the combination of Vigil autologous tumor cell immunotherapy and durvalumab PD-L1 inhibitor in patients with locally advanced or metastatic women's cancers, inclusive, but not limited to breast, ovarian, cervical, uterine, fallopian, primary peritoneal, and endometrial regardless of the number of prior therapies. This will be a 2-part study. The first part will be a safety run-in comprised of 2 cohorts that will use a 3 + 3 design to determine the Vigil dose in Part 2. Patients in Cohort 1 will receive a low dose of Vigil (1x10\^6 cells/intradermal (ID) injection) in combination with durvalumab (1500 mg (if \> 30 kg) IV over 60 minutes) every 4 weeks. Patients in Cohort 2 will receive Vigil at 1x10\^7 cells/ID injection and durvalumab (1500mg (if \> 30 kg) IV over 60 minutes) every 4 weeks. If needed, patients in Cohort -1 will receive Vigil at 1x10\^5 cells/ID injection and durvalumab (1500mg (if \> 30 kg) IV over 60 minutes) every 4 weeks. The enrollment of the first two patients in each Cohort of Part 1 will be staggered by 2 weeks. In Part 2 of the study, patients meeting study eligibility criteria will receive Vigil at the dose determined in Part 1 and durvalumab (1500mg (if \> 30 kg) IV over 60 minutes) every 4 weeks. As of March 13, 2018, Part 2 of the study will not be initiated due to limited enrollment. Currently only patients who have Vigil immunotherapy available from Gradalis protocol CL-PTL-119 may be considered for the study. Radiological assessment of tumor response or alternative assessments of disease status should be performed at screening, Cycle 3 and every 2 cycle thereafter, and end of treatment (EOT) using RECIST 1.1 and investigator assessment as applicable. Tumor biopsy for correlative studies including but not limited to scoring of tumor infiltrating lymphocyte (TIL) and PD-1 / PD-L1 expression analysis should be obtained at tissue procurement and at Cycle 3, and optional biopsies thereafter if the patient has accessible tissue. Peripheral blood mononuclear cells (PBMC) for correlative studies should be obtained at pre-procurement if applicable, and prior to study regimen administration at Cycle 1, Cycle 3, Cycle 5 and EOT. Patient survival will be followed for 1 year after last dose of either Vigil or durvalumab.
