Subsequent doses: Administer over 30–60 minutes.1
Dosage
Adults
Breast Cancer
Pertuzumab, Trastuzumab, and Docetaxel for HER2-overexpressing Metastatic Breast Cancer
IVInitially, pertuzumab 840 mg in combination with trastuzumab 8 mg/kg (administered by IV infusion over 90 minutes) and docetaxel 75 mg/m2 (administered by IV infusion), followed every 3 weeks thereafter by pertuzumab 420 mg in combination with trastuzumab 6 mg/kg (administered by IV infusion over 30–90 minutes) and docetaxel 75 or 100 mg/m2.1
If a dose is missed or delayed, and the time between 2 sequential infusions is <6 weeks, administer pertuzumab 420 mg; do not wait until the next scheduled dose.1 If the time between 2 sequential infusions is ≥6 weeks, administer pertuzumab dose of 840 mg (i.e., same dose as initially used), followed by pertuzumab 420 mg every 3 weeks thereafter.1
Dosage Modification for Toxicity and Contraindications to Continued Therapy
Dosage reductions not recommended.1 If toxicities occur, reduce infusion rate or temporarily or permanently discontinue therapy based on causality.1
Infusion or Hypersensitivity Reactions
If clinically important infusion reactions occur, reduce infusion rate or interrupt infusion and administer appropriate medical therapy.1
If severe infusion or hypersensitivity reactions occur, immediately discontinue infusion and consider permanent discontinuance of therapy.1
Monitor patients carefully until signs and symptoms have completely resolved.1
Left Ventricular Dysfunction
If left ventricular ejection fraction (LVEF) decreases to <40% or to 40–45% with an absolute decrease from baseline of ≥10%, withhold pertuzumab and trastuzumab for at least 3 weeks.1 (See Left Ventricular Dysfunction under Cautions.)
Reassess LVEF within approximately 3 weeks.1 If LVEF has recovered to >45% or to 40–45% with an absolute decrease from baseline of <10%, may resume pertuzumab therapy.1 If LVEF has not improved or has declined further, strongly consider discontinuing pertuzumab and trastuzumab, unless benefits outweigh risks.1
Consult prescribing information for docetaxel for detailed information on dosage modifications for this drug.1
Withhold or discontinue pertuzumab if trastuzumab is withheld or discontinued; however, if docetaxel is discontinued, may continue pertuzumab and trastuzumab therapy.1
Special Populations
Dosage adjustment not necessary based on body weight or baseline albumin concentration.1 (See Special Populations under Pharmacokinetics.)
Hepatic Impairment
No specific dosage recommendations at this time.1 (See Hepatic Impairment under Cautions.)
Renal Impairment
Mild (Clcr 60–90 mL/minute) or moderate (Clcr 30–60 mL/minute) renal impairment: No dosage adjustment required.1
Severe renal impairment (Clcr <30 mL/minute): No specific dosage recommendations at this time due to limited data.1 (See Renal Impairment under Cautions.)
Geriatric Patients
No specific dosage recommendations at this time.1 (See Geriatric Use under Cautions.)

Warnings/Precautions
Warnings
Fetal/Neonatal Morbidity and Mortality
May cause fetal harm.1 Embryotoxicity and fetotoxicity demonstrated in animals.1 Oligohydramnios, delayed fetal kidney development, and embryo-fetal death observed following administration of pertuzumab to pregnant cynomolgus monkeys at dosages producing concentrations 2.5–20 times that of human clinical exposure (based on peak plasma concentrations).1
Embryotoxic and fetotoxic effects likely to be present during all trimesters of pregnancy.1
Verify pregnancy status prior to initiation of pertuzumab.1 Advise women of childbearing potential to use effective contraceptive methods during and for 6 months after discontinuance of drug.1
If used during pregnancy or if patient becomes pregnant during therapy, apprise of potential fetal hazard.1 (See Pregnancy under Cautions.) Monitor for development of oligohydramnios in patients who become pregnant during therapy; perform appropriate fetal testing if oligohydramnios occurs.1 Efficacy of IV hydration in the management of oligohydramnios secondary to pertuzumab exposure unknown.1
Sensitivity Reactions
Infusion or Hypersensitivity Reactions
Infusion reactions, including hypersensitivity and anaphylaxis, reported.1 Most common infusion reactions reported were pyrexia, chills, fatigue, headache, asthenia, hypersensitivity, vomiting, dysgeusia, and myalgia.1
Closely observe patients for 60 minutes after first infusion and for 30 minutes after subsequent infusions.1 If infusion or hypersensitivity reactions occur, may need to reduce infusion rate or temporarily or permanently discontinue therapy.1 (See Infusion or Hypersensitivity Reactions under Dosage and Administration.)
Other Warnings and Precautions
Left Ventricular Dysfunction
Decreases in LVEF reported with inhibitors of HER2, including pertuzumab.1 6 9 In principal efficacy study, pertuzumab not associated with increased incidence of symptomatic left ventricular systolic dysfunction (LVSD, congestive heart failure [CHF]) or decrease in LVEF compared with placebo.1 2 Median time to development of LVSD appears to be around cycle 4.6
Safety not established in patients with baseline LVEF ≤50%, prior history of CHF, decreases in LVEF to <50% during prior trastuzumab therapy, or conditions that could impair left ventricular function (e.g., uncontrolled hypertension, recent MI, serious cardiac arrhythmia requiring treatment, cumulative prior anthracycline exposure >360 mg/m2 of doxorubicin or its equivalent).1
Risk of LVSD possibly increased in patients who received prior anthracycline therapy or had prior radiation therapy to the chest area.1
Assess LVEF prior to initiation of therapy and at regular intervals (e.g., every 3 months) during treatment.1
If substantial decreases in LVEF occur, may need to temporarily or permanently discontinue therapy.1 (See Left Ventricular Dysfunction under Dosage and Administration.)
Evaluation of HER2
Assess breast tumors for HER2 overexpression prior to initiation of therapy because safety and efficacy of pertuzumab established only in patients with HER2-overexpressing tumors.1
Immunohistochemistry (IHC) assays (e.g., Dako Herceptest), which measure overexpression of the HER2 protein, and fluorescent in situ hybridization (FISH) (e.g., Dako HER2 FISH PharmDx), which measures amplification of the HER2 oncogene, are tests most commonly used.1 3 5
In principal efficacy study, patients were required to have disease demonstrating an IHC score of 3+ or a FISH amplification ratio of ≥2.1 2 Limited data for patients with FISH-positive tumors that lack HER2 overexpression.1
Select laboratories with demonstrated proficiency in the specific technology being used; improper assay performance can lead to unreliable results.1
Specific Populations
Pregnancy
Category D.1 (See Fetal/Neonatal Morbidity and Mortality under Cautions.)
If used during pregnancy or if patient becomes pregnant while receiving therapy, apprise of potential fetal hazard.1 Encourage patient to enroll in the MotHER Pregnancy Registry (800-690-6720), and immediately notify Genentech Adverse Event Line (888-835-2555).1
Lactation
Not known whether pertuzumab is distributed into milk.1 Discontinue nursing or the drug.1
Pediatric Use
Safety and efficacy not established.1
Geriatric Use
No overall differences in safety, efficacy, and pharmacokinetics relative to younger adults.1
Hepatic Impairment
Pharmacokinetics not studied in patients with hepatic impairment.1
Renal Impairment
Systemic exposure not altered by mild or moderate renal impairment; no dosage adjustment required.1 (See Renal Impairment under Dosage and Administration and also see Special Populations under Pharmacokinetics.)
Limited data in patients with severe renal impairment.1
Common Adverse Effects

Actions
-
Binds specifically to extracellular dimerization domain (subdomain II) of HER2 protein, blocking heterodimerization of HER2 with other ligand-bound members of the HER family (i.e., epidermal growth factor receptor [EGFR]/HER1, HER3, HER4).1 2 3
-
Blockade of HER2 heterodimerization (particularly with HER3) results in inhibition of ligand-activated intracellular signaling through 2 major signal pathways, mitogen-activated protein kinase (MAPK) and phosphoinositide 3-kinase (PI3K/Akt), potentially causing cell growth arrest and apoptosis, respectively.1 2 3 8 13 17
-
Mediates antibody-dependent cell-mediated cytotoxicity (ADCC).1 13 16
-
Exhibits complementary mechanisms of action with trastuzumab; therefore, combined use with trastuzumab may result in more comprehensive inhibition of HER2 signaling.2 7 13 17
Advice to Patients
-
Risk of fetal harm (e.g., embryo-fetal death, birth defects).1 Necessity of advising women of childbearing potential to use effective contraceptive methods during and for 6 months after discontinuance of drug.1 Encourage women who have been exposed to pertuzumab during pregnancy to enroll in the MotHER Pregnancy Registry by contacting 800-690-6720.1 (See Fetal/Neonatal Morbidity and Mortality under Cautions.)
-
Importance of discontinuing breast-feeding during therapy.1
-
Risk of infusion or hypersensitivity reactions.1
-
Risk of decreased LVEF.1
-
Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs, as well as any concomitant illnesses.1
-
Importance of informing patients of other important precautionary information.1 (See Cautions.)
