Brief Summary:
The primary objective of this study is to determine the anti-tumor activity, as measured by overall response rate (ORR) of atezolizumab in combination with bevacizumab in patients with chemotherapy resistant CRC and positivity for MSI-like molecular signature. This is an international, open-label single arm (non-randomized), one-stage phase II trial.

A highly effective method of birth control is defined as those which result in low failure rate (i.e. less than 1% per year) when used consistently and correctly.
  • Female subjects who are breast feeding should discontinue nursing before trial registration and until 6 months after the last bevacizumab treatment and 5 months after the last atezolizumab treatment.
