Protocol 141

Anti PD-1 Therapy in Combination with Platinum Chemotherapy for Platinum Resistant Ovarian, Fallopian Tube, and Primary Peritoneal Cancer

Patient Population

Main Criteria Only

  • Patients who have a diagnosis of ovarian, fallopian tube, or primary peritoneal cancer who had a complete response to primary treatment of platinum based chemotherapy, have progressed within 6 months of completing platinum based chemotherapy and have subsequently received at least one, non-platinum, cytotoxic chemotherapy agent
  • Have relapsed, refractory or progressive disease following last line of treatment
  • Have measurable disease with at least 1 unidimensional lesion based on RECIST 1.1
  • Have a performance status of 0 to 1 on the ECOG Performance Scale
  • Demonstrate adequate organ function

Number of Patients

  • Up to 27 patients

Study Objectives

Primary Objectives

  • To determine the clinical response rate of platinum chemotherapy and pembrolizumab in platinum chemotherapy pretreated ovarian, fallopian tube and primary peritoneal cancer
  • To examine whether retreatment with platinum chemotherapy in platinum resistant ovarian, fallopian tube and primary peritoneal cancers improves progression free survival by concurrent administration of pembrolizumab

Treatment Information

After all screening procedures have been completed, pembrolizumab 200mg will be administered as a 30-minute IV infusion on Day 1 of each 3-week cycle. Carboplatin will be administered as a 30-minute IV infusion on Day 8 and Day 15 of each 3-week cycle.

On-Site Study Visits

  • The trial drug, pembrolizumab will be administered at the University of Washington Medical Center Clinical Research Center on Day 1 of each 21 day cycle. Carboplatin will be administered per standard of care at the patient’s own oncology clinic.
  • The treatment period is to repeat the 3-week cycles for up to 2 years.
  • Patients may be taken off treatment including but not limited to progression and unacceptable adverse events.
  • Tumor imaging will be arranged every 3 cycles per standard of care.

Long-Term Follow-up

  • A follow-up 30 day evaluation will be performed upon study completion
  • Following the 30 days, efforts will be made to collect radiologic imaging reports every 3 months for 1 year to monitor disease status
  • After a year total in the follow-up phase, radiologic imaging reports will be collected every 6 months

Other Procedures During Study Visits

  • History and physical exam
  • Clinical blood tests plus research blood collection for immune monitoring
