Salvage Ovarian FANG™ Vaccine + Carboplatinum

Gradalis, Inc.1 enrolled

Overview

This is a Phase II study of Vigil™ autologous tumor cell vaccine integrated with carboplatinum. All patients will have Vigil™ prepared and stored from ovarian tumor cells obtained at the time of primary surgical debulking. Patients meeting eligibility criteria will receive either carboplatinum alone (AUC 6/30 minute infusion) or carboplatinum (AUC 5/30 minute infusion) and taxol (175 mg/m2/3 hour infusion) one day prior to Vigil™ 1.0 x 10e7 cells/intradermal injection, once every 3 weeks.

Patients meeting eligibility criteria will receive Vigil™ 1.0 x 10e7 cells/intradermal injection once every 3 weeks.

CarboplatinumDRUG

Patients meeting eligibility criteria will receive either carboplatinum alone (AUC 6/30 minute infusion) or carboplatinum (AUC 5/30 minute infusion) and taxol (175 mg/m2 3-hour infusion) one day prior to Vigil™ 1.0 x 10e7 cells/ intradermal injection, once every three weeks. At recurrence, patients allergic to carboplatinum will receive docetaxel 75 mg/m2/1 hour infusion, one day prior to Vigil™ 1.0 x 10e7 cells/intradermal injection every 3 weeks. Patients with stable disease (SD) or better and unable to tolerate continued chemotherapy will be allowed to continue Vigil™ alone for up to 12 cycles or as long as vaccine is available; conversely, patients with SD or better who exhaust Vigil™ supply may continue on chemotherapy alone.

Outcomes

Primary Outcomes

Time to Progression (TTP)

Time to progression (TTP) will be determined following Carboplatinum integrated with Vigil vaccine in patients failing standard of care in study CL-PTL 105 or in those not otherwise qualifying after vaccine production. This will be measured from the treatment start date (date of first dose) to either the date the patient is first recorded as having disease recurrence (even if the patient went off treatment because of toxicity), or the date of death if the patient dies due to any causes before progression.

Time frame: 24 months

Response Rate

Response will be evaluated using the revised Response Evaluation Criteria in Solid Tumors (RECIST) guideline.

Time frame: Up to 12 months

Secondary Outcomes

Immune Analysis in Blood

To determine if subjects will have a positive (defined as \>10 ELISPOTS from baseline) immune response to Vigil. Blood was collected to compare ELISPOT results from baseline until 30 days after last dose.

Time frame: Baseline, End of Treatment (30 days after last dose) up to 12 months
