Current Primary Outcome Measures (submitted: May 21, 2020)

• Response rate (RR) assessed by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 [ Time Frame: 6 months ]
  The point estimate and the 95% exact CIs will be reported for RR. The comparison with the historical control rate will be conducted by examining whether the 95% confidence internal covers the historical control rate.
• Progression-free survival (PFS) assessed by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 [ Time Frame: 6 months ]
  Analyzed using the Kaplan-Meier method. Kaplan-Meier estimates of the survival function with 95% confidence intervals (CIs) at specific time points (using Greenwood's formula for the standard error) were computed. Comparisons with the historical control PFS will be conducted by examining whether the 95% confidence internal covers the historical control proportions.

Original Primary Outcome Measures (submitted: January 20, 2017)

Progression-free survival (PFS) assessed by RECIST v1.1 [ Time Frame: 6 months ]

Analyzed using the Kaplan-Meier method. Kaplan-Meier estimates of the survival function with 95% CIs at specific time points (using Greenwood's formula for the standard error) were computed.

Descriptive Information

• Brief Title: Pembrolizumab and Carboplatin in Treating Patients With Relapsed or Refractory Ovarian, Fallopian Tube, or Primary Peritoneal Cancer
• Official Title: Anti-PD-1 Therapy in Combination With Platinum Chemotherapy for Platinum Resistant Ovarian, Fallopian Tube, and Primary Peritoneal Cancer
• Brief Summary: This phase I/II trial studies how well pembrolizumab and carboplatin work in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has come back (relapsed) or has not responded to previous treatment (refractory). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving pembrolizumab and carboplatin with platinum resistant chemotherapy may work better than platinum chemotherapy alone in treating patients with ovarian, fallopian tube, or primary peritoneal cancer.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the clinical response rate of platinum chemotherapy and pembrolizumab (MK-3475) in platinum chemotherapy pretreated ovarian, fallopian tube, and primary peritoneal.

II. 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 MK-3475.

SECONDARY OBJECTIVES:

I. To assess the safety and tolerability of concurrent administration of MK-3475 with platinum chemotherapy in patients with platinum resistant recurrent ovarian, fallopian tube, and primary peritoneal cancers.

II. To determine the relationship between PD-L1 expression and response to the combination of MK-3475 and platinum.

III. To assess the overall survival of patients treated with the combination of MK-3475 and platinum.

EXPLORATORY OBJECTIVE:

I. To explore whether treatment with MK-3475 and platinum alters soluble factors in sera, peripheral immune responses and immune cell profile.

OUTLINE:

Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1 and carboplatin IV over 30 minutes on days 8 and 15. Cycles repeat every 21 days for up to 24 months in the absence of disease progression or unacceptable toxicity.
