Hemorrhagic events, some of which were fatal, have involved gastrointestinal tract, respiratory tract, tumor, urinary tract, and brain; interrupt therapy for Grade 3 or 4 hemorrhagic events until resolution to Grade less than or equal to 1 or baseline, then resume at a reduced dose; discontinue therapy in patients without resolution of Grade 3 or 4 hemorrhagic events; perform serial complete blood counts and physical examinations

Adrenal hemorrhage observed in animal studies; monitor adrenal function in case of stress such as surgery, trauma or severe infection

Monitor urine protein; interrupt treatment for 24-hr urine protein ≥3 g; discontinue for repeat episodes of protein ≥3 g despite dose reductions or nephrotic syndrome

Hyperthyroidism, some followed by hypothyroidism, have been reported; monitor thyroid function at baseline, periodically during treatment and as clinically indicated; initiate and/or adjust therapies for thyroid dysfunction as appropriate

Impaired wound healing reported; withhold therapy for at least 3 weeks prior to elective surgery; do not administer for at least 2 weeks following major surgery and until adequate wound healing; safety of resumption of therapy after resolution of wound healing complications has not been established

Advise women of childbearing potential of potential hazard to fetus

Prolonged QT intervals and Torsade de Pointes may occur in a dose-dependent manner; use caution in patients at higher risk for developing QT interval prolongation; consider monitoring with on-treatment ECG and electrolytes

Based on animal reproduction studies and its mechanism of action, fetal harm may occur when administered to pregnant females
