Brief Summary:
The investigators hypothesize that tumor cell killing by cytotoxic chemotherapy exposes the immune system to high levels of tumor antigens.The combination of Paclitaxel/Carboplatin and Pembrolizumab may result in deeper and more durable responses compared with standard chemotherapy alone.

Condition or disease Intervention/treatment Phase
Fallopian Tube Carcinoma Peritoneal Carcinoma Epithelial Ovarian Cancer Drug: Pembrolizumab Drug: Paclitaxel Drug: Carboplatin Phase 2

Detailed Description:

This is a single arm, open-label, phase II study to assess pathologic objective response rate (complete response + partial response) in patients treated with pembrolizumab, paclitaxel and carboplatin for advanced stage III or IV Ovarian, Fallopian Tube, or Peritoneal Carcinoma (EOC).

Eligible patients will undergo tissue biopsies to confirm diagnosis, followed by 3 to 4 cycles of neoadjuvant chemotherapy (NACT).

  2. Patients must undergo diagnostic laparoscopy for disease assessment for tissue biopsies to confirm diagnosis with planned interval tumor reductive surgery after completion of 3-4 cycles of treatment. For those not medically fit to undergo laparoscopy, as determined by the Investigator. (interventional radiology) IR-guided core biopsies may be used.

  9. Negative urine or serum pregnancy ≤ 72 hours (i.e. 3 days) prior to receiving the first dose of study medication if not surgically sterilized. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
