Indication
PERJETA® (pertuzumab) is a HER2/neu receptor antagonist indicated for use in combination with Herceptin® (trastuzumab) and docetaxel as neoadjuvant treatment of patients with HER2‑positive, locally advanced, inflammatory, or early stage breast cancer (either greater than 2 cm in diameter or node positive) as part of a complete treatment regimen for early breast cancer. This indication is based on demonstration of an improvement in pathological complete response rate. No data are available demonstrating improvement in event-free survival or overall survival.
Limitations of Use:
The safety of PERJETA as part of a doxorubicin-containing regimen has not been established
The safety of PERJETA administered for greater than 6 cycles for early breast cancer has not been established

Results of the phase II randomized NeoSphere trial (referred to as Study 2 in the PERJETA prescribing information). Treatment cycles were received every 3 weeks. During the neoadjuvant period, all patients received 4 cycles of their respective therapies. PERJETA dosing: 840 mg loading dose, 420 mg for subsequent cycles; Herceptin dosing: 8 mg/kg loading dose, 6 mg/kg for subsequent cycles (administered to complete 1 year of treatment); docetaxel dosing: 75 mg/m2 each cycle, escalated to 100 mg/m2 at investigator’s discretion if initial dose was well tolerated. Patients in the PERJETA + Herceptin neoadjuvant arm received 4 cycles of docetaxel + Herceptin as adjuvant therapy. pCR in breast was the primary endpoint studied in the NeoSphere trial.1
One patient had unknown hormone receptor status. The patient did not achieve a pCR.

PERJETA administration can result in subclinical and clinical cardiac failure manifesting as decreased LVEF and CHF. Evaluate cardiac function prior to and during treatment. Discontinue PERJETA treatment for a confirmed clinically significant decrease in left ventricular function
Exposure to PERJETA can result in embryo-fetal death and birth defects. Advise patients of these risks and the need for effective contraception

Important Safety Information
Boxed WARNINGS: Left Ventricular Dysfunction and Embryo-Fetal Toxicity
PERJETA administration can result in subclinical and clinical cardiac failure manifesting as decreased LVEF and CHF. Evaluate cardiac function prior to and during treatment. Discontinue PERJETA treatment for a confirmed clinically significant decrease in left ventricular function
Exposure to PERJETA can result in embryo-fetal death and birth defects. Advise patients of these risks and the need for effective contraception
Verify the pregnancy status of females of reproductive potential prior to the initiation of PERJETA. Advise pregnant women and females of reproductive potential that exposure to PERJETA in combination with trastuzumab during pregnancy or within 7 months prior to conception can result in fetal harm, including embryo‑fetal death or birth defects. Advise females of reproductive potential to use effective contraception during treatment and for 7 months following the last dose of PERJETA in combination with trastuzumab
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to PERJETA during pregnancy. Encourage women who receive PERJETA in combination with trastuzumab during pregnancy or within 7 months prior to conception, to enroll in the MotHER Pregnancy Registry by contacting 1‑800‑690‑6720 or visiting http://www.motherpregnancyregistry.com/
If PERJETA is administered during pregnancy, or if a patient becomes pregnant while receiving PERJETA or within 7 months following the last dose of PERJETA in combination with trastuzumab, health care providers and patients should immediately report PERJETA exposure to Genentech at 1‑888‑835‑2555
Additional Important Safety Information
PERJETA is contraindicated in patients with known hypersensitivity to pertuzumab or to any of its excipients.
Left Ventricular Dysfunction (LVD)
In Study 1, for patients with MBC, left ventricular dysfunction, which includes symptomatic left ventricular systolic dysfunction (LVSD) (congestive heart failure) and decreases in left ventricular ejection fraction (LVEF), occurred in 4.4% of patients in the PERJETA-treated group and in 8.3% of patients in the placebo-treated group
In Study 2, for patients receiving neoadjuvant treatment, the incidence of LVSD was higher in PERJETA-treated groups than in the trastuzumab and docetaxel group. An increased incidence of LVEF declines was observed in patients treated with PERJETA in combination with trastuzumab and docetaxel. In the overall treatment period, LVEF decline >10% and a drop to less than 50% occurred in 1.9% of patients treated with neoadjuvant trastuzumab and docetaxel as compared to 8.4% of patients treated with neoadjuvant PERJETA in combination with trastuzumab and docetaxel
In Study 3, for patients receiving neoadjuvant treatment, in the overall treatment period, LVEF decline >10% and a drop to less than 50% occurred in 6.9% of patients treated with PERJETA plus trastuzumab and FEC followed by PERJETA plus trastuzumab and docetaxel, in 16.0% of patients treated with PERJETA plus trastuzumab and docetaxel following FEC, and in 10.5% of patients treated with PERJETA in combination with TCH
Assess LVEF prior to initiation of PERJETA and at regular intervals (eg, every 3 months in the metastatic setting and every 6 weeks in the neoadjuvant setting) during treatment to ensure that LVEF is within your institution’s normal limits
If LVEF is <45%, or is 45% to 49% with a 10% or greater absolute decrease below the pretreatment value, withhold PERJETA and trastuzumab and repeat LVEF assessment within approximately 3 weeks. Discontinue PERJETA and trastuzumab if LVEF has not improved or has declined further
Infusion-Associated Reactions
PERJETA has been associated with infusion reactions
In Study 1, when all drugs were administered on the same day, the most common infusion reactions in the PERJETA-treated group (≥1.0%) were fatigue, dysgeusia, hypersensitivity, myalgia, and vomiting
In Study 2 and Study 3, PERJETA was administered on the same day as the other study treatment drugs. Infusion reactions were consistent with those observed in Study 1, with a majority of reactions being National Cancer Institute - Common Terminology Criteria for Adverse Events (NCI-CTCAE v3.0) Grades 1‑2
If a significant infusion reaction occurs, slow or interrupt the infusion and administer appropriate medical therapies. Monitor patients carefully until complete resolution of signs and symptoms. Consider permanent discontinuation in patients with severe infusion reactions
Hypersensitivity Reactions/Anaphylaxis
In Study 1, the overall frequency of hypersensitivity/anaphylaxis reactions was 10.8% in the PERJETA‑treated group and 9.1% in the placebo-treated group. The incidence of Grades 3‑4 reactions was 2.0% and 2.5%, respectively, according to NCI-CTCAE (version 3)
In Study 2 and Study 3, hypersensitivity/anaphylaxis events were consistent with those observed in Study 1
Patients should be observed closely for hypersensitivity reactions. Severe hypersensitivity, including anaphylaxis, has been observed in clinical trials of PERJETA. Medications to treat such reactions, as well as emergency equipment, should be available for immediate use
HER2 Testing
Detection of HER2 protein overexpression is necessary for selection of patients appropriate for PERJETA therapy because these are the only patients studied and for whom benefit has been shown
Most Common Adverse Reactions
Neoadjuvant Treatment of Breast Cancer
The most common adverse reactions (>30%) with PERJETA in combination with trastuzumab and docetaxel were alopecia, diarrhea, nausea, and neutropenia. The most common NCI-CTCAE v3.0 Grades 3‑4 adverse reactions (>2%) were neutropenia, febrile neutropenia, leukopenia, and diarrhea
The most common adverse reactions (>30%) with PERJETA in combination with trastuzumab and docetaxel when given for 3 cycles following 3 cycles of FEC were fatigue, alopecia, diarrhea, nausea, vomiting, and neutropenia. The most common NCI-CTCAE (version 3) Grades 3‑4 adverse reactions (>2%) were neutropenia, leukopenia, febrile neutropenia, diarrhea, left ventricular dysfunction, anemia, dyspnea, nausea, and vomiting
The most common adverse reactions (>30%) with PERJETA in combination with docetaxel, carboplatin, and trastuzumab (TCH) for 6 cycles were fatigue, alopecia, diarrhea, nausea, vomiting, neutropenia, thrombocytopenia, and anemia. The most common NCI-CTCAE (version 3) Grades 3‑4 adverse reactions (>2%) were neutropenia, febrile neutropenia, anemia, leukopenia, diarrhea, thrombocytopenia, vomiting, fatigue, ALT increased, hypokalemia, and hypersensitivity
