Safety and Efficacy of CRS-207 With Epacadostat in Platinum Resistant Ovarian, Fallopian or Peritoneal Cancer

Not Recruiting

Trial ID: NCT02575807


This 2-part, Phase 1/2 study will test investigational cancer drugs known as CRS-207, epacadostat (IDO), and pembrolizumab (pembro). The purpose of this study is to find out how safe it is to give the investigational drugs to women with platinum-resistant ovarian, fallopian tube, or peritoneal cancer and if it helps patients with these types of cancer live longer or can help shrink or slow the growth of cancer.
