- Safety and tolerability (Adverse Event reported per CTCAE v5) [ Time Frame: At each study visit up to final safety follow up visit: every week for the first 6 weeks and then every 3 weeks ]Incidence of Adverse Event reported per CTCAE v5
- Best overall response rate as assessed by the Gynecological Cancer Intergroup (GCIC) Carbohydrate Antigen 125 (CA-125) criteria [ Time Frame: Every 3 weeks ]Percentage of patients with a minimum 50% reduction in CA-125 serum levels lasting for 28 days relative to pre-treatment CA-125 serum level per the GCIC criteria.
- Best Overall Tumor Response Rate [ Time Frame: Within 21 days of treatment initiation and then every 9 weeks ]Percentage of patients whose best overall response is either a Complete Response or a Partial Response according to Response Evaluation Criteria In Solid Tumors version 1.1 (RECIST 1.1) criteria over the the total number of patients evaluable.
- Rate of patients with immune response [ Time Frame: Days 64, 85 and 211 ]Percentage of patients who achieve an immune response established by the detection of antigen-specific T cell.
