Current Primary Outcome Measures (submitted: July 14, 2023)

Recurrence Free Survival (RFS) [ Time Frame: Time from randomization date to either the date of first recurrence or the date of death if the participant dies prior to recurrence, assessed up to 10 years. ]

Disease recurrence will be evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 by local and central radiology. RFS is defined as the time from randomization or from surgery/procurement to the event of disease recurrence/progression or death due to any cause.

• Original Primary Outcome Measures (submitted: January 26, 2015): Recurrence Free Survival [ Time Frame: 7-14 months after sugery and chemotherapy ]

Current Secondary Outcome Measures (submitted: July 14, 2023)

Overall survival (OS) [ Time Frame: OS will be evaluated from time of randomization until date of death can be obtained, assessed up to 10 years. ]

OS is defined as the time from randomization to date of death due to any cause.

Original Secondary Outcome Measures (submitted: January 26, 2015)

Overall Survival [ Time Frame: 54 months ]

The assumed median survival in the control arm is 54 months.

Descriptive Information

• Brief Title: A Trial of Vigil for Participants With Ovarian Cancer
• Official Title: A Randomized, Double-Blind, Placebo-Controlled Phase 2 Trial of Vigil Engineered Autologous Tumor Cell Immunotherapy in Subjects With Stage IIIb-IV Ovarian Cancer in Clinical Complete Response Following Surgery and Primary Chemotherapy
• Brief Summary: The goal of this clinical trial is to compare participants with ovarian, fallopian tube or primary peritoneal cancer when treated with investigational product (Vigil) compared to placebo. The main question it aims to answer is "Will participants who receive treatment with Vigil have a longer time to disease recurrence versus the participants that were not given Vigil?"

Detailed Description

This is a multicenter, randomized, double-blind, placebo-controlled, Phase 2 study of maintenance Vigil Ovarian (gemogenovatucel-T) engineered autologous tumor cells (EATC) in women with Stage IIIb, IIIc or IV high-grade papillary serous/ clear cell / endometrioid ovarian, fallopian tube or primary peritoneal cancer. Subjects will have had a minimum of 4 and a maximum of 12 doses of Vigil prepared and stored from ovarian tumor cells obtained at the time of primary surgical debulking or initial diagnostic / evaluative laparoscopy (tissue for immunotherapy manufacture must be procured prior to initiation of neoadjuvant chemotherapy). An equal number of placebo doses will be manufactured. Subjects eligible for randomization will have achieved a clinically defined complete response following primary surgery and adjuvant chemotherapy. Clinical complete response (cCR) is defined as no evidence of maligancy on chest x-ray and CT scan or MRI of the abdomen and pelvis, CA-125 antigen level ≤ units/mL, and no findings on physical examination or symptoms suggestive of active cancer.

Investigational treatment must start no less than 3 weeks and no more than 8 weeks following completion of chemotherapy.

Approximately 86 subjects will be randomized 1:1 to to Group A (Vigil 1.0 X 10e7 cells/injection) or Group B (placebo). Randomization will be stratified by (i) extent of surgical cytoreduction (complete/microscopic versus macroscopic residual disease) and (ii) neoadjuvant versus adjuvant chemotherapy. Participants will receive Vigil or placebo by intradermal injection once a month for at least 4 and up to a maximum of 6 doses determined by the number of doses of Vigil manufactured for that subject.

Participants will be managed in an outpatient setting. Image assessment with chest x-ray and CT scan or MRI of the abdomen and pelvis will be completed every 3 months in Years 1-3, then every 6 months in Years 4 and 5 and yearly through Year 10. At the time the participant recurs, the participant will enter long term follow-up for survival status and post treatment therapies received.

• Study Type: Interventional
• Study Phase: Phase 2
• Study Design: Allocation: Randomized; Intervention Model: Parallel Assignment; Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor); Primary Purpose: Treatment

Condition

• Ovarian Cancer
• Ovarian Neoplasms

Intervention

• Biological: Vigil
  The bi-shRNAfurin and GMCSF Augmented Autologous Tumor Cell Vaccine, Vigil is made up of irradiated autologous tumor cells which have been electroporated ex vivo with the Vigil plasmid designed to suppress expression of both the TGFβ1 and TGFβ2 proteins while simultaneously expressing rhGMCSF protein.
  Other Names:

  • bi-shRNAfurin and GMCSF Autologous Tumor Cell Immunotherapy
  • FANG vaccine
• Other: Placebo
  To maintain placebo effect and eliminate bias due to volumetric differences, the number of Vigil doses manufactured from harvested tissue (except if below 4) will be used to guide manufacture of the same number of doses of placebo for each subject. Placebo will consist of "freeze" media [10% DMSO (dimethyl sulfoxide; Cryoserv USP; Mylan Institutional USP), 1% Human Serum Albumin (ABO Pharmaceuticals) in Plasma-Lyte A, pH 7.4 (Baxter)]. Depending upon randomization assignment, placebo or Vigil will be delivered in identical vials and drawn up in 'covered' syringes for intradermal injection.

Study Arms

• Active Comparator: Group A
  Vigil immunotherapy will be administered at a concentration of 1.0 x 10e7 cells/dose given via intradermal injection every 4 weeks for a minimum of 4 and a maximum of 6 administrations as determined by the number of doses manufactured and as long as the subject is clinically stable and recurrence free.
  Intervention: Biological: Vigil
• Placebo Comparator: Group B
  Placebo will be administered via intradermal injection every 4 weeks for a minimum of 4 and a maximum of 6 administrations as determined by the number of doses manufactured and as long as the subject is clinically stable and recurrence free.
  Intervention: Other: Placebo
