Boxed WARNINGS and Additional Important Safety Information

Gastrointestinal (GI) perforation: Avastin administration can result in the development of GI perforation, in some cases resulting in fatality. GI perforation, sometimes associated with intra-abdominal abscess, occurred throughout treatment with Avastin. Permanently discontinue Avastin therapy in patients with GI perforation.

Wound healing complication: Avastin administration can result in the development of wound dehiscence, in some instances resulting in fatality. Permanently discontinue Avastin therapy in patients with wound dehiscence requiring medical intervention. The appropriate interval between termination of Avastin and subsequent elective surgery has not been determined.

Hemorrhage: Severe, and in some cases fatal, pulmonary hemorrhage can occur in patients with NSCLC treated with chemotherapy and Avastin. Do not administer Avastin to patients with recent hemoptysis (≥1/2 tsp of red blood). Permanently discontinue Avastin in patients with serious hemorrhage and initiate aggressive medical management.

Additional serious adverse events included non-GI fistula formation, arterial thromboembolic events, hypertensive crisis, reversible posterior leukoencephalopathy syndrome, neutropenia and infection, nephrotic syndrome, and congestive heart failure.
