These data are likely to underestimate the true adverse event rates due to the reporting mechanisms used in this study

• When continued beyond first progression in MCRC, no new safety signals were observed in the TML study (ML18147) when Avastin was administered in second-line MCRC patients who progressed on an Avastin containing regimen in first-line MCRC. The safety data was consistent with the known safety profile established in first- and second-line MCRC

Adverse reactions leading to discontinuation of Avastin occurred in 15% of patients in the Avastin and atezolizumab arm. The most common adverse reactions leading to Avastin discontinuation were hemorrhages (4.9%), including bleeding varicose vein, hemorrhage and gastrointestinal, subarachnoid, and pulmonary hemorrhages; and increased transaminases or bilirubin (0.9%). Adverse reactions leading to interruption of Avastin occurred in 46% of patients in the Avastin and atezolizumab arm; the most common (≥2%) were proteinuria (6%); infections (6%); hypertension (6%); liver function laboratory abnormalities including increased transaminases, bilirubin, or alkaline phosphatase (4.6%); gastrointestinal hemorrhages (3%); thrombocytopenia/decreased platelet count (4.3%); and pyrexia (2.4%)
