Pertuzumab can cause subclinical and clinical cardiac failure manifesting as decreased left ventricular ejection fraction (LVEF) and congestive heart failure (CHF). Evaluate cardiac function prior to and during treatment. Discontinue pertuzumab treatment for a confirmed clinically significant decrease in left ventricular function.
Exposure to pertuzumab can cause embryo-fetal death and birth defects. Advise patients of these risks and the need for effective contraception.
Dosage guidance:
Safety: Actively manage modifiable cardiac risk factors (smoking, hypertension, diabetes, dyslipidemia, obesity) before initiating treatment (Ref). Observe patients for 30 to 60 minutes after each pertuzumab infusion and before subsequent doses of trastuzumab products or docetaxel. Medications and equipment for the treatment of hypersensitivity should be available for immediate use during infusion. Do not substitute pertuzumab (IV) with pertuzumab/trastuzumab/hyaluronidase (SUBQ).
Clinical considerations: Select patients for treatment based on HER2 protein overexpression or HER2 gene amplification in tumor specimens. Refer to the protocol or institutional guidance for additional details of off-label dosing.
Biliary tract cancer, metastatic, HER2 positive (previously treated) (off-label use): Initial dose: IV: 840 mg followed by a maintenance dose of 420 mg once every 3 weeks (in combination with trastuzumab); continue until disease progression or unacceptable toxicity (Ref).
Breast cancer, early, HER2 positive, neoadjuvant treatment: IV: 840 mg followed by a maintenance dose of 420 mg every 3 weeks for 3 to 6 cycles; may be administered as one of the regimens below. Postoperatively, continue pertuzumab and trastuzumab (or trastuzumab/hyaluronidase) to complete 1 year of treatment (up to 18 cycles) or until disease progression or unacceptable toxicity (whichever occurs first).
Four preoperative cycles of pertuzumab, trastuzumab (or trastuzumab/hyaluronidase), and docetaxel, followed by 3 postoperative cycles of fluorouracil, epirubicin, and cyclophosphamide (FEC) (Ref) or
Three or four preoperative cycles of FEC (alone) followed by 3 or 4 preoperative cycles of pertuzumab, trastuzumab (or trastuzumab/hyaluronidase), and docetaxel (Ref) or
Six preoperative cycles of pertuzumab, trastuzumab (or trastuzumab/hyaluronidase), docetaxel, and carboplatin (Ref) or
Four preoperative cycles of dose-dense doxorubicin and cyclophosphamide alone, followed by 4 preoperative cycles of pertuzumab, trastuzumab (or trastuzumab/hyaluronidase), and paclitaxel (Ref).

Missed doses or delays: If <6 weeks has elapsed, administer pertuzumab 420 mg (maintenance dose) as soon as possible; do not wait until the next planned dose. If ≥6 weeks has elapsed, readminister pertuzumab 840 mg (loading dose) over 60 minutes, and then follow with a maintenance dose of pertuzumab 420 mg (over 30 to 60 minutes) every 3 weeks thereafter.
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
CrCl ≥30 mL/minute: No dosage adjustment necessary.
CrCl <30 mL/minute: There are no dosage adjustments provided in the manufacturer's labeling (has not been studied).
There are no dosage adjustments provided in the manufacturer's labeling (has not been studied).
Note: Dose reductions are not recommended for pertuzumab; if trastuzumab (or trastuzumab/hyaluronidase) is withheld, pertuzumab should also be withheld; if the trastuzumab product is discontinued, permanently discontinue pertuzumab. Other concomitant anticancer therapies may also require treatment interruption, dosage reduction, and/or discontinuation.

Concerns related to adverse effects:
• Cardiotoxicity: Pertuzumab may cause left ventricular dysfunction, including symptomatic heart failure. Decreases in left ventricular ejection fraction (LVEF) have been reported with HER2 inhibitors, including pertuzumab. In the pertuzumab-treated patients with metastatic breast cancer, left ventricular dysfunction, including symptomatic left ventricular systolic dysfunction (LVSD), occurred in a small percentage of patients. Patients who received prior anthracycline therapy or chest irradiation may be at an increased risk for cardiotoxicity. In the early breast cancer neoadjuvant setting, left ventricular dysfunction, including asymptomatic left ventricular dysfunction and/or LVSD, was observed in patients treated with pertuzumab; however, LVEF recovered to ≥50% in a majority of patients. In the early breast cancer adjuvant setting, symptomatic heart failure (NYHA class III/IV) with a LVEF decline ≥10% and a drop to <50% occurred in a small number of patients (most of these events were reported in anthracycline-treated patients); almost half of the pertuzumab-treated patients who experienced symptomatic heart failure recovered. Asymptomatic or mildly symptomatic (NYHA class II) declines in LVEF ≥10% and a drop to <50% were reported in a small percentage of pertuzumab-treated patients, of whom a majority recovered at data cutoff. Of note, patients with pretreatment LVEF <50%, history of congestive heart failure, LVEF decreases to <50% during prior trastuzumab treatment, or conditions which could impair left ventricular function (eg, uncontrolled hypertension, recent myocardial infarction, serious arrhythmia requiring treatment, or cumulative lifetime anthracycline exposure >360 mg/m2 doxorubicin or its equivalent) were excluded from studies.
• GI adverse events: Diarrhea occurred more frequently in patients receiving pertuzumab in combination with trastuzumab and docetaxel, compared to patients receiving only trastuzumab and docetaxel. Diarrhea occurred more frequently in the first pertuzumab cycle and was generally grade 1 or 2; diarrhea was usually managed with loperamide and rarely required treatment delay (Swain 2017).
• Hypersensitivity: Pertuzumab may cause hypersensitivity reactions, including anaphylaxis. The overall frequency of hypersensitivity/anaphylaxis was 11%, with grade 3 and 4 events occurring in a small percentage of patients. Severe hypersensitivity, including anaphylaxis, has been reported; some events were fatal. Angioedema has also been reported.
• Infusion reaction: Pertuzumab may cause serious infusion-related reactions, including fatal events. Infusion reactions have occurred on the day of infusion in up to one-fourth of patients; grades 3 and 4 events have been reported in a small number of patients. The most common infusion reactions included fever, chills, fatigue, headache, weakness, hypersensitivity, and vomiting; reactions during cycle 2 included fatigue, dysgeusia, hypersensitivity, myalgia, and vomiting.
Special populations:
• Older age: The incidence of adverse reactions (including decreased appetite, weight loss, anemia, weakness, dysgeusia, peripheral neuropathy, and hypomagnesemia) was increased in pertuzumab-treated patients ≥65 years of age (compared to patients <65 years of age).
Dosage form specific issues:
• Do not interchange: Pertuzumab (IV) and pertuzumab/trastuzumab/hyaluronidase (SUBQ) are not interchangeable. Verify product label prior to reconstitution and administration to prevent medication errors. Dosing and treatment schedules differ between pertuzumab (Perjeta) and pertuzumab/trastuzumab/hyaluronidase (Phesgo).
Other warnings/precautions:
• HER2 expression: Establish HER2 status (HER2 overexpression or HER2 gene amplification) in tumor specimen prior to treatment. Improper assay performance (including suboptimally fixed tissue, failure to use specified reagents, deviation from assay instructions, and failure to include appropriate assay controls) may lead to unreliable results.

Verify pregnancy status prior to treatment initiation in patients who could become pregnant. Advise patients of the risks of exposure during pregnancy and the need for effective contraception. Patients who could become pregnant should use effective contraception during therapy and for 7 months after the last dose of pertuzumab in combination with trastuzumab (or trastuzumab/hyaluronidase).
Pertuzumab is a humanized monoclonal antibody (IgG1). Human IgG crosses the placenta. Fetal exposure is dependent upon the IgG subclass, maternal serum concentrations, placental integrity, newborn birth weight, and gestational age, generally increasing as pregnancy progresses. The lowest exposure would be expected during the period of organogenesis and the highest during the third trimester (Clements 2020; Palmeira 2012; Pentsuk 2009).
Outcome data following exposure to pertuzumab as monotherapy or in combination with trastuzumab or other agents during pregnancy are limited (Al-Shamsi 2023, Andrikopoulou 2021; Gougis 2023). Based on the mechanism of action of pertuzumab and data from animal reproduction studies, in utero exposure to pertuzumab may result in fetal death and birth defects. Oligohydramnios or oligohydramnios sequence may occur resulting in pulmonary hypoplasia, skeletal anomalies, and neonatal death. Monitor for oligohydramnios if exposure occurs during pregnancy or within 7 months prior to conception; conduct appropriate fetal testing if oligohydramnios occurs. Advise patients of the risks of fetal exposure.
European Society for Medical Oncology (ESMO) guidelines for managing breast cancer during pregnancy recommend delaying treatment with HER2-targeted agents until after delivery in pregnant patients with HER2-positive disease (ESMO [Loibl 2023]).
Advise patients to immediately report to health care provider if pregnancy is suspected during treatment. If pertuzumab exposure occurs during pregnancy or exposure to pertuzumab in combination with trastuzumab (or trastuzumab/hyaluronidase) occurs within 7 months following the last dose of pertuzumab, report the exposure to Genentech (888-835-2555).
It is not known if pertuzumab is present in breast milk.
Pertuzumab is a humanized monoclonal antibody (IgG1). Human IgG is present in breast milk; concentrations are dependent upon IgG subclass and postpartum age (Anderson 2021).
Immunoglobulin is present in breast milk. According to the manufacturer, the decision to breastfeed during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and benefits of treatment to the mother. The extended half-life of pertuzumab and the 7-month wash out period for trastuzumab (or trastuzumab/hyaluronidase) should be considered for decisions regarding breastfeeding after treatment is completed.
Assess HER2 protein expression or HER2 gene amplification in tumor specimen prior to treatment. Evaluate pregnancy status (prior to treatment in patients who could become pregnant). Assess cardiac function, including LVEF at baseline, and approximately every 12 weeks during treatment (more frequently for declines). Monitor for infusion reaction, diarrhea, and hypersensitivity (monitor for hypersensitivity reactions for 60 minutes following the initial pertuzumab infusion and for 30 minutes following subsequent infusions).
The American Society of Clinical Oncology hepatitis B virus (HBV) screening and management provisional clinical opinion (ASCO [Hwang 2020]) recommends HBV screening with hepatitis B surface antigen, hepatitis B core antibody, total Ig or IgG, and antibody to hepatitis B surface antigen prior to beginning (or at the beginning of) systemic anticancer therapy; do not delay treatment for screening/results. Detection of chronic or past HBV infection requires a risk assessment to determine antiviral prophylaxis requirements, monitoring, and follow-up.
Additional cardiovascular monitoring (guideline recommendations): Comprehensive assessment prior to treatment including a history and physical examination, screening for cardiovascular disease risk factors such as hypertension, diabetes, dyslipidemia, obesity, and smoking (ASCO [Armenian 2017], ESC [Lyon 2022]). Obtain a baseline echocardiography (transthoracic preferred) and repeat every 3 months during treatment (may reduce to every 4 to 6 months if normal and asymptomatic), assess more frequently if clinically indicated and obtain echocardiography within 12 months after completion; in high- and very high-risk patients, assess troponin and natriuretic peptide at baseline and consider assessing every 2 to 3 cycles, and at 3 and 12 months after completion of therapy; in low- and moderate-risk patients, consider troponin and natriuretic peptide at baseline (post-anthracycline), every 3 months and 12 months after completion of therapy (ESC [Lyon 2022]).
Pertuzumab is a recombinant humanized monoclonal antibody which targets the extracellular human epidermal growth factor receptor 2 protein (HER2) dimerization domain. Inhibits HER2 dimerization and blocks HER downstream signaling halting cell growth and initiating apoptosis. Pertuzumab binds to a different HER2 epitope than trastuzumab so that when pertuzumab is combined with trastuzumab, a more complete inhibition of HER2 signaling occurs (Baselga 2012).
