Vismodegib Combined With Atezolizumab in Platinum Resistant Ovarian, Fallopian Tube, and Primary Peritoneal Cancer

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This trial will treat patients with platinum resistant ovarian, fallopian tube or primary peritoneal cancer as defined by a progression free interval within six months of completion of most recent platinum-based treatment with a combination of vismodegib and atezolizumab. Despite recent improvements in treatment of ovarian cancer with the introduction of PARP inhibitors, response rates to therapy in the platinum resistant setting remain dismal with response rates of only 10-20% reported for single agent cytotoxic therapies. Given the poor prognosis and limited treatment options for these patients, this population is considered appropriate for trials of novel therapeutic candidates.
