Spots Global Cancer Trial Database for A Trial of FANG™ Vaccine for Participants With Ovarian Cancer

Study Description

Brief Summary: This was a clinical trial for women with ovarian cancer scheduled to have an operation to remove the cancerous tissue. The cancer cells removed during the planned surgery were used to attempt to make the investigational product, named Vigil. Vigil is considered an immunotherapy. In this study, participants who met the requirements to be in the study and if Vigil was successfully made from the participants cancer cells, participants underwent treatment with their standard chemotherapy regimen. At the end of the standard chemotherapy regimen and if there was no evidence of remaining cancer, participants were randomly assigned to receive the Vigil or would be assigned to the standard of care group, which in this study meant no further treatment was given to the participant. The purpose of this study was to compare the difference between the participants who received Vigil versus the usual care after completion of standard chemotherapy and to determine if Vigil delayed or prevented ovarian cancer from coming back.

Detailed Description: This was a Phase II open-label study of Vigil™ autologous tumor cell vaccine trial administered to women with Stage III/IV epithelial ovarian cancer. Tumor was harvested at the time of surgical debulking (standard of medical care). Participants who achieved clinical complete response (CR) following primary surgical debulking and front-line doublet chemotherapy were randomized 2:1 to either treatment with Vigil (Group A) or standard of care without maintenance therapy (Group B). After randomization, participants were stratified into cohorts by baseline CA-125 (greater than 10 to less than 20 units/mL versus less than or equal to 10 units/mL). For data analysis, participants could further be stratified by surgical stage (Stage IV or suboptimal debulking (\> 1cm residual), Stage III disease versus Stage III disease with optimal debulking (\< 1cm residual). Participants enrolled in Group A (Vigil) received 1.0 x 10e7 cells / intradermal injection of gene transfected autologous tumor cells, Vigil™, once a month for up to 12 doses as long as sufficient material was available or until trial endpoints were met. Enough harvested tissue to provide a minimum of 4 monthly injections was required for entry into the study. Participants enrolled in Group B (Standard of Care, SOC) were observed and assessed until trial endpoints were met. Protocol Amendment 8, June 19, 2014 removed randomization such that all patients screening for enrollment into the main portion of the trial (including those who previously had tumor tissue harvested) would be assigned to Group A (Vigil). Both groups of participants were seen once a month in an outpatient setting. Hematologic function, liver enzymes, renal function and electrolytes were monitored monthly. Immune function analysis including ELISPOT analysis of cytotoxic T cell function to autologous tumor antigens were monitored at (≤ 24 hours before the third cycle chemotherapy (post debulking), baseline (screening); prior to Vigil injection at Months 2, 3, 6 and EOT. CA-125 was monitored at baseline, every month for the first year, every 3 months +/- 2 weeks for the second and third year. Participants assigned to group A were allowed to continue treatment with Vigil until disease recurrence or exhaustion of the patient's vaccine supply. If ≥ Grade 2 toxicity by NCI Common Toxicity Criteria (excluding Grade 2 fever ≤ 24 hours and Grade 2 and 3 injection site reactions) developed related to study treatment, the vaccine dose was reduced by 50% and continued on a monthly basis. Efficacy assessments included time to disease recurrence, immune surrogate markers, and quality of life questionnaire (FACT-O, Version 4). Safety assessments included physical examination, performance status, and vital signs. Adverse events were recorded using CTCAE version 3.
