Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Recurrent Epithelial Ovarian Cancer Recurrent Fallopian Tube Cancer Recurrent Peritoneal Cancer Other: DPX-Survivac Drug: Cyclophosphamide Drug: Epacadostat (INCB024360) Phase 1 Phase 2

Detailed Description:

The Phase 1b component is a multicenter, non-randomized, open label, uncontrolled, safety and effectiveness study to identify the recommended Phase 2 dose (R2PD) of epacadostat in combination with DPX-Survivac and cyclophosphamide.

The Phase 2 component was initially a multicenter, randomized, open-label study to evaluate the safety and effectiveness of DPX-Survivac + cyclophosphamide with or without the RP2D of epacadostat. The design of the study has been amended to a single arm study in which up to 16 evaluable subjects will be enrolled to received DPX-Survivac plus intermittent low dose cyclophosphamide (i.e. treatment arm 2).

  • Life expectancy ≥ 6 months
  • Meet protocol-specified laboratory requirements

Key Exclusion Criteria:

  • Eligible for otherwise curative treatment or undergoing concurrent therapy
  • Prior receipt of survivin based vaccines or immune checkpoint inhibitors (e.g. anti-CTLA-4, anti-PD-1, anti-PD-L1, or any other antibody or drug specifically targeting T cell co-stimulation) or an IDO inhibitor
  • Concurrent second malignancy other than non-melanoma skin cancer, cervical carcinoma in situ, or controlled bladder cancer
  • Clinical ascites

  • Malignant bowel obstruction
  • History of autoimmune disease requiring treatment within the last two years (except vitiligo or diabetes)
  • Recent history of thyroiditis
  • Presence of a serious acute infection or chronic infection
  • Active central nervous system (CNS) or leptomeningeal metastasis (brain metastases)
  • GI condition that might limit absorption of oral agents
  • Other serious intercurrent chronic or acute illness, including myocardial infarction or cerebrovascular event within 6 months
  • Ongoing treatment with steroid therapy or other immunosuppressive
  • Receipt of monoamine oxidase inhibitors (MAOIs) or UGT1A9 inhibitors
  • Receipt of live attenuated vaccines
  • Acute or chronic skin and/or microvascular disorders
  • Edema or lymphedema in the lower limbs > grade 2
