Perjeta Boxed Warnings
Left ventricular dysfunction. Embryo-fetal toxicty.
Risk of left ventricular dysfunction. Assess LVEF prior to initiation and at regular intervals during treatment (eg, every 12wks for MBC or EBC [once for neoadjuvant therapy]); withhold pertuzumab and trastuzumab for LVEF decreases (see full labeling); discontinue if LVEF has not improved or clinically significant decrease in left ventricular function is confirmed. Pretreatment LVEF value of ≤50%, history of CHF, decreases in LVEF to <50% during prior trastuzumab therapy, uncontrolled hypertension, recent MI, serious cardiac arrythmia requiring treatment or a cumulative prior anthracycline exposure to >360mg/m2 of doxorubicin or its equivalent: not studied. Monitor for signs/symptoms of infusion reactions; slow or interrupt infusion and treat if occur; permanently discontinue if severe. Embryo-fetal toxicity. Advise females of reproductive potential to use effective contraception during and for 7 months after last dose. Pregnancy: exclude status prior to initiation. Nursing mothers.
