17. Female patients must be either postmenopausal or, if premenopausal, must have a negative pregnancy test and agree to use two forms of contraception if sexually active during the treatment period, for at least 5 months after the last dose of atezolizumab and 6 months after the last dose of bevacizumab.

16. Uncontrolled inter-current illness including, but not limited to, ongoing or active infection (except viral hepatitis), symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
