ical Studies (14). ] The population was aged 21–88 years (median 59), 46.0% male and 84.1% white. The population included 1089 first‑ and second‑line mCRC patients who received a median of 11 doses of Avastin, 480 first‑line metastatic NSCLC patients who received a median of 8 doses of Avastin, 592 MBC patients who had not received chemotherapy for metastatic disease received a median of 8 doses of Avastin, 163 glioblastoma patients who received a median of 9 doses of Avastin, and 337 mRCC patients who received a median of 16 doses of Avastin.
Surgery and Wound Healing Complications
The incidence of post‑operative wound healing and/or bleeding complications was increased in patients with mCRC receiving Avastin as compared to patients receiving only chemotherapy. Among patients requiring surgery on or within 60 days of receiving study treatment, wound healing and/or bleeding complications occurred in 15% (6/39) of patients receiving bolus‑IFL plus Avastin as compared to 4% (1/25) of patients who received bolus‑IFL alone.
In Study 7, events of post‑operative wound healing complications (craniotomy site wound dehiscence and cerebrospinal fluid leak) occurred in patients with previously treated glioblastoma: 3/84 patients in the Avastin alone arm and 1/79 patients in the Avastin plus irinotecan arm.

Hemorrhage
The incidence of epistaxis was higher (35% vs. 10%) in patients with mCRC receiving bolus‑IFL plus Avastin compared with patients receiving bolus‑IFL plus placebo. All but one of these events were Grade 1 in severity and resolved without medical intervention. Grade 1 or 2 hemorrhagic events were more frequent in patients receiving bolus‑IFL plus Avastin when compared to those receiving bolus‑IFL plus placebo and included gastrointestinal hemorrhage (24% vs. 6%), minor gum bleeding (2% vs. 0), and vaginal hemorrhage (4% vs. 2%). [ See Boxed Warning, Dosage and Administration (2.4), Warnings and Precautions (5.3). ]
Venous Thromboembolic Events
The incidence of Grade 3–4 venous thromboembolic events was higher in patients with mCRC or NSCLC receiving Avastin with chemotherapy as compared to those receiving chemotherapy alone. The risk of developing a second subsequent thromboembolic event in mCRC patients receiving Avastin and chemotherapy was increased compared to patients receiving chemotherapy alone. In Study 1, 53 patients (14%) on the bolus‑IFL plus Avastin arm and 30 patients (8%) on the bolus‑IFL plus placebo arm received full dose warfarin following a venous thromboembolic event. Among these patients, an additional thromboembolic event occurred in 21% (11/53) of patients receiving bolus‑IFL plus Avastin and 3% (1/30) of patients receiving bolus‑IFL alone.
The overall incidence of Grade 3–4 venous thromboembolic events in Study 1 was 15.1% in patients receiving bolus‑IFL plus Avastin and 13.6% in patients receiving bolus‑IFL plus placebo. In Study 1, the incidence of the following Grade 3–4 venous thromboembolic events was higher in patients receiving bolus‑IFL plus Avastin as compared to patients receiving bolus‑IFL plus placebo: deep venous thrombosis (34 vs. 19 patients) and intra‑abdominal venous thrombosis (10 vs. 5 patients).
