Dosing in kidney impairment
Renal Impairment Dose adjustments of PERJETA are not needed in patients with mild (creatinine clearance [CLcr] 60 to 90 mL/min) or moderate (CLcr 30 to 60 mL/min) renal impairment. No dose adjustment can be recommended for patients with severe renal impairment (CLcr less than 30 mL/min) because of the limited pharmacokinetic data available [see Clinical Pharmacology ] .

An observation period of 30 to 60 minutes is recommended after each PERJETA infusion and before commencement of any subsequent administration of trastuzumab or trastuzumab hyaluronidase-oysk, or taxane [see Warnings and Precautions ].
In patients receiving an anthracycline-based regimen, administer PERJETA and trastuzumab or trastuzumab hyaluronidase-oysk after completion of the anthracycline. Metastatic Breast Cancer (MBC) When administered with PERJETA, the recommended initial dose of docetaxel is 75 mg/m 2 administered as an intravenous infusion. The dose may be escalated to 100 mg/m 2 administered every 3 weeks if the initial dose is well tolerated.
Neoadjuvant Treatment of Breast Cancer Administer PERJETA every 3 weeks for 3 to 6 cycles as part of one of the following treatment regimens [see Clinical Studies (14.2 , 14.3) ] : Four preoperative cycles of PERJETA in combination with trastuzumab or trastuzumab hyaluronidase-oysk and docetaxel followed by 3 postoperative cycles of fluorouracil, epirubicin, and cyclophosphamide (FEC) Three or four preoperative cycles of FEC alone followed by 3 or 4 preoperative cycles of PERJETA in combination with docetaxel and trastuzumab or trastuzumab hyaluronidase-oysk Six preoperative cycles of PERJETA in combination with docetaxel, carboplatin, and trastuzumab (TCH) or trastuzumab hyaluronidase-oysk (escalation of docetaxel above 75 mg/m 2 is not recommended) Four preoperative cycles of dose-dense doxorubicin and cyclophosphamide (ddAC) alone followed by 4 preoperative cycles of PERJETA in combination with paclitaxel and trastuzumab or trastuzumab hyaluronidase-oysk Following surgery, administer PERJETA and trastuzumab or trastuzumab hyaluronidase-oysk to complete 1 year of treatment (up to 18 cycles) or until disease recurrence or unmanageable toxicity, whichever occurs first.
Adjuvant Treatment of Breast Cancer As part of a regimen including standard anthracycline- and/or taxane-based chemotherapy, administer PERJETA in combination with trastuzumab or trastuzumab hyaluronidase-oysk every 3 weeks for a total of 1 year (up to 18 cycles) or until disease recurrence or unmanageable toxicity, whichever occurs first.
Administer PERJETA on Day 1 of the first taxane-containing cycle [see Clinical Studies ] .
Preparation for Administration Administer as an intravenous infusion only. Do not administer as an intravenous push or bolus. Do not mix PERJETA with other drugs. Preparation Prepare the solution for infusion, using aseptic technique, as follows: Parenteral drug products should be inspected visually for particulates and discoloration prior to administration, whenever solution and container permit.
Withdraw the appropriate volume of PERJETA solution from the vial(s) using a sterile needle and syringe. Dilute into a 250 mL 0.45% Sodium Chloride Injection or 0.9% Sodium Chloride Injection infusion bag. Mix diluted solution by gentle inversion. Do not shake. Administer immediately once prepared. If the diluted infusion solution is not used immediately, it can be stored refrigerated at 2°C to 8°C (36 °F to 46 °F) for up to 24 hours.
Dilute with 0.45% Sodium Chloride Injection or 0.9% Sodium Chloride Injection only. Do not use 5% Dextrose Injection.

Safety data
Reported adverse events (FAERS)
Liver injury (LiverTox)
ELikelihood score E: Unlikely cause of clinically apparent acute liver injury.
Pertuzumab is a humanized monoclonal antibody to the human epidermal growth factor receptor 2 (HER2) which is used in combination with other antineoplastic agents in the therapy of refractory, advanced breast cancer. Pertuzumab has been implicated in rare instances of transient, occasionally marked serum enzyme elevations, but has not been linked to instances of clinically apparent liver injury with jaundice.
ABCDEA: well known cause; E: unlikely cause. [HD]: high doses only.
Pregnancy and lactation
Pregnancy
8.1 Pregnancy 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. Risk Summary Based on its mechanism of action and findings in animal studies, PERJETA can cause fetal harm when administered to a pregnant woman. There are no available data on the use of PERJETA in pregnant women.
However, in post-marketing reports, use of another HER2/neu receptor antagonist (trastuzumab) during pregnancy resulted in cases of oligohydramnios and oligohydramnios sequence manifesting as pulmonary hypoplasia, skeletal abnormalities, and neonatal death. In an animal reproduction study, administration of pertuzumab to pregnant cynomolgus monkeys during the period of organogenesis resulted in oligohydramnios, delayed fetal kidney development, and embryo-fetal deaths at clinically relevant exposures that were 2.5 to 20-fold greater than exposures in humans receiving the recommended dose, based on C max [see Data ]. Apprise the patient of the potential risks to a fetus.
There are clinical considerations if PERJETA in combination with trastuzumab is used during pregnancy or within 7 months prior to conception [see Clinical Considerations ] . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Monitor women who received PERJETA in combination with trastuzumab during pregnancy or within 7 months prior to conception for oligohydramnios.
If oligohydramnios occurs, perform fetal testing that is appropriate for gestational age and consistent with community standards of care. Data Animal Data Pregnant cynomolgus monkeys were treated on Gestational Day (GD)19 with loading doses of 30 to 150 mg/kg pertuzumab, followed by bi-weekly doses of 10 to 100 mg/kg. These dose levels resulted in clinically relevant exposures of 2.5 to 20-fold greater than exposures in humans receiving the recommended dose, based on C max . Intravenous administration of pertuzumab from GD19 through GD50 (period of organogenesis) was embryotoxic, with dose-dependent increases in embryo-fetal death between GD25 to GD70.
The incidences of embryo-fetal loss were 33, 50, and 85% for dams treated…
Breastfeeding (LactMed)
Pertuzumab milk concentrations were collected in one mother. Concentrations were low, consistent with it being a large protein molecule with a molecular weight of about 148,000 Da. It is also likely to be partially destroyed in the infant's gastrointestinal tract and absorption by the infant is probably minimal. Until more data become available, pertuzumab should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant. The manufacturer recommends that breastfeeding be discontinued during pertuzumab therapy and for 7 months after the last dose.
