A Phase 1b/2 Study of an Immunotherapeutic Vaccine, DPX-Survivac With Low Dose Cyclophosphamide and Epacadostat (INCB024360) in Patients With Recurrent Ovarian Cancer
T cell activating therapy DPX-Survivac, low dose oral cyclophosphamide, and IDO1 inhibitor epacadostat will be tested together for the first time in patients with recurrent ovarian, fallopian tube, or peritoneal cancer to determine the safety and potential immune-modulating activity of the combination of these agents.
• Histologically confirmed, stage IIc-IV epithelial ovarian, fallopian tube or peritoneal cancer
• Platinum-resistant or -sensitive subjects after completing first-line treatment (debulking surgery and adjuvant or neoadjuvant treatment with standard of care treatment such as carboplatin and paclitaxel). Subjects may have had any number of subsequent lines of chemotherapy.
• Must have evidence of progressive disease with either biochemical (i.e. rising CA-125) and/or radiologic progression
• Must have measurable disease by RECIST v1.1, a successful pre-treatment tumor biopsy, and be willing to undergo tumor biopsy during treatment
• Ambulatory with an ECOG 0-1
• Life expectancy ≥ 6 months
• Meet protocol-specified laboratory requirements
