Testing the PD-1 Antibody, MK3475, Given With Ziv-aflibercept in Patients With Advanced Cancer

Official Title

A Phase 1 Trial of MK-3475 Plus Ziv-Aflibercept in Patients With Advanced Solid Tumours


This phase I trial studies the side effects and best dose of ziv-aflibercept when given together with pembrolizumab in treating patients with solid tumours that have spread to other places in the body (advanced). Ziv-afibercept works by decreasing blood and nutrient supply to the tumour, which may result in shrinking the tumour. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumour cells to grow and spread. Giving ziv-aflibercept together with pembrolizumab may be a better treatment for patients with advanced solid tumours.

Trial Description

Primary Outcome:

  • Recommended combination dose of ziv-aflibercept and pembrolizumab
Secondary Outcome:
  • Objective response rate (ORR)
  • Progression-free survival
  • Overall survival
  • Time-to-progression
  • To determine the safety, tolerability and recommended phase II dosing for the combination of ziv-aflibercept plus MK-3475 (pembrolizumab) in patients with unresectable stage III or stage IV melanoma, renal cell cancer, ovarian cancer, colorectal cancer, or sarcoma.
  • To obtain preliminary estimates of progression-free survival at 6 months.
  • To obtain preliminary estimates of the rate of 1-year overall survival.
  • To obtain preliminary estimates of the response rate.
  • To obtain preliminary estimates of time to progression.
  • To perform correlative sciences that provide information regarding the mechanisms of action for this combination treatment.
This is a dose-escalation and dose expansion study of ziv-aflibercept. Patients receive pembrolizumab intravenously (IV) over approximately 30 minutes and ziv-aflibercept IV over 1-2 hours on day 1. Cycles repeat every 2 weeks for up to 2 years in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for at least 12 weeks.
