The FDA has approved Perjeta (pertuzumab), in combination with Herceptin (trastuzumab) and chemotherapy for adjuvant treatment for a certain type of early breast cancer.
Indications: Perjeta is a HER2/neu receptor antagonist indicated for use in combination with trastuzumab and chemotherapy as adjuvant treatment of patients with HER2-positive early breast cancer at high risk of recurrence.
Dosage and administration: Administer by intravenous infusion postoperatively every 3 weeks for a total of 1 year (up to 18 cycles).
Efficacy and safety: Approval is based on results of a phase 3 study showing that the combination significantly reduced the risk of invasive breast cancer recurrence or death by 18% vs trastuzumab and chemotherapy alone.
Side effects/risks: The most common adverse reactions are diarrhea, nausea, alopecia, fatigue, peripheral neuropathy, and vomiting.
