1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
5 WARNINGS AND PRECAUTIONS Infusion-Related Reactions: PERJETA can cause serious infusion reactions, including fatal events: Monitor for signs and symptoms. If a significant infusion-associated reaction occurs, slow or interrupt the infusion and administer appropriate medical therapies.
3 ) Hypersensitivity Reactions/Anaphylaxis: PERJETA can cause hypersensitivity reactions, including anaphylaxis: Monitor for signs and symptoms, including angioedema. If a severe hypersensitivity reaction/anaphylaxis occurs, discontinue the infusion immediately and administer appropriate medical therapies.
1 Left Ventricular Dysfunction PERJETA can cause left ventricular dysfunction, including symptomatic heart failure. Decreases in LVEF have been reported with drugs that block HER2 activity, including PERJETA. Assess LVEF prior to initiation of PERJETA and at regular intervals during treatment to ensure that LVEF is within normal limits.
5) ] . In the PERJETA-treated patients with MBC in CLEOPATRA, left ventricular dysfunction occurred in 4% of patients and symptomatic left ventricular systolic dysfunction (LVSD) (congestive heart failure) occurred in 1% of patients.
Patients who received prior anthracyclines or prior radiotherapy to the chest area may be at higher risk of decreased LVEF or left ventricular dysfunction. In patients receiving PERJETA as a neoadjuvant treatment in combination with trastuzumab and docetaxel in NeoSphere, LVEF decline > 10% and a drop to < 50% occurred in 8% of patients and left ventricular dysfunction occurred in 3% of patients.
LVEF recovered to ≥ 50% in all these patients. In patients receiving neoadjuvant PERJETA in TRYPHAENA, LVEF decline > 10% and a drop to < 50% occurred in 7% of patients treated with PERJETA plus trastuzumab and FEC followed by PERJETA plus trastuzumab and docetaxel, 16% of patients treated with PERJETA plus trastuzumab and docetaxel following FEC, and 11% of patients treated with PERJETA in combination with TCH.

LVEF recovered to ≥ 50% in all but one patient. In patients receiving neoadjuvant PERJETA in BERENICE, in the neoadjuvant period, LVEF decline ≥ 10% and a drop to < 50% as measured by ECHO/MUGA assessment occurred in 7% of patients treated with PERJETA plus trastuzumab and paclitaxel following ddAC, and 2% of patients treated with PERJETA plus trastuzumab and docetaxel following FEC.
Ejection fraction decreased (asymptomatic LVD) occurred in 7% of patients treated with PERJETA plus trastuzumab and paclitaxel following ddAC and 4% of the patients treated with PERJETA plus trastuzumab and docetaxel following FEC in the neoadjuvant period.

Asymptomatic or mildly symptomatic (NYHA Class II) declines in LVEF ≥ 10% and a drop to < 50% were reported in 3% of PERJETA-treated patients, of whom 80% recovered at the data cutoff. PERJETA has not been studied in patients with a pretreatment LVEF value of < 50%, a prior history of CHF, decreases in LVEF to < 50% during prior trastuzumab therapy, or conditions that could impair left ventricular function such as uncontrolled hypertension, recent myocardial infarction, serious cardiac arrhythmia requiring treatment or a cumulative prior anthracycline exposure to > 360 mg/m 2 of doxorubicin or its equivalent.
2 Embryo-Fetal Toxicity Based on its mechanism of action and findings in animal studies, PERJETA can cause fetal harm when administered to a pregnant woman. PERJETA is a HER2/neu receptor antagonist. Cases of oligohydramnios and oligohydramnios sequence manifesting as pulmonary hypoplasia, skeletal abnormalities, and neonatal death have been reported with use of another HER2/neu receptor antagonist (trastuzumab) during pregnancy.
5 to 20 times the exposure in humans at the recommended dose, based on C max . 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.
3) ] . 1) ]. In CLEOPATRA, on the first day, when only PERJETA was administered, infusion-related reactions occurred in 13% of patients and < 1% were Grade 3 or 4. The most common infusion reactions (≥ 1%) were pyrexia, chills, fatigue, headache, asthenia, hypersensitivity, and vomiting.
During the second cycle when all drugs were administered on the same day, the most common infusion reactions in the PERJETA-treated group (≥ 1%) were fatigue, dysgeusia, hypersensitivity, myalgia, and vomiting. In APHINITY, when PERJETA was administered in combination with trastuzumab and chemotherapy on the same day, infusion-related reactions occurred in 21% of patients with <1% of patients experiencing Grade 3-4 events.
Observe patients closely for 60 minutes after the first infusion and for 30 minutes after subsequent infusions of PERJETA. If a significant infusion-related reaction occurs, slow or interrupt the infusion, and administer appropriate medical therapies.
Monitor patients carefully until complete resolution of signs and symptoms. 5) ]. 4 Hypersensitivity Reactions/Anaphylaxis PERJETA can cause hypersensitivity reactions, including anaphylaxis. In CLEOPATRA, the overall frequency of hypersensitivity/anaphylaxis reactions was 11% in PERJETA-treated patients, with Grade 3 – 4 hypersensitivity reactions and anaphylaxis occurring in 2% of patients.
In NeoSphere, TRYPHAENA, BERENICE, and APHINITY, hypersensitivity/anaphylaxis events were consistent with those observed in CLEOPATRA. In APHINITY, the overall frequency of hypersensitivity/anaphylaxis was 5% in the PERJETA treated group.
The incidence was highest in the PERJETA plus TCH treated group (8%) with 1% Grade 3 – 4 events. Observe patients closely for hypersensitivity reactions. 1) ] . Angioedema has been described in post-marketing reports. Medications to treat such reactions, as well as emergency equipment, should be available for immediate use prior to administration of PERJETA.
PERJETA is contraindicated in patients with known hypersensitivity to pertuzumab or to any of its excipients [see Contraindications (4) ].
