About Pertuzumab

Indications of Pertuzumab

Pertuzumab is a HER2-targeted monoclonal antibody approved only for use in combination regimens for HER2-positive breast cancer, based on confirmed HER2 overexpression/gene amplification by an FDA-approved test. It is not used as monotherapy.

Established (FDA-approved) indications

SettingCombinationPatient population
Neoadjuvant (before surgery)With trastuzumab and chemotherapyHER2-positive, locally advanced, inflammatory, or early-stage breast cancer (tumor greater than 2 cm or node-positive), as part of a complete treatment regimen
Adjuvant (after surgery)With trastuzumab and chemotherapyHER2-positive early breast cancer at high risk of recurrence
MetastaticWith trastuzumab and docetaxelHER2-positive metastatic breast cancer in patients who have not received prior anti-HER2 therapy or chemotherapy for metastatic disease

Pertuzumab is not approved for HER2-negative breast cancer or for cancers other than breast cancer, and is not established as effective outside of these specific combination regimens.

Dosage & Administration of Pertuzumab

Pertuzumab should be used only after confirming HER2 positivity by a validated test, and is always given in combination with trastuzumab and chemotherapy, administered by intravenous infusion under the supervision of a physician experienced in cancer chemotherapy.

Dosing

DoseRegimen
Initial (loading) dose840 mg by IV infusion over 60 minutes
Maintenance dose420 mg by IV infusion over 30 to 60 minutes, every 3 weeks, together with trastuzumab and chemotherapy, for the number of cycles specified by the approved regimen being used

Missed or delayed dose

  • Less than 6 weeks since the last infusion: give the 420 mg maintenance dose as soon as possible; do not wait for the next scheduled dose.
  • 6 weeks or more since the last infusion: re-administer the 840 mg initial dose over 60 minutes, then resume the 420 mg dose every 3 weeks.

Dose modification for cardiac dysfunction

Pertuzumab and trastuzumab are withheld for a significant drop in left ventricular ejection fraction (LVEF) and resumed only if LVEF recovers per protocol criteria. No dose reduction of Pertuzumab is recommended for any indication; a dose is either given in full or withheld.

Frequently Asked Questions about Pertuzumab

What is Pertuzumab used for?

Pertuzumab is used, always in combination with trastuzumab and chemotherapy, to treat HER2-positive breast cancer, including certain early-stage cases before or after surgery (neoadjuvant/adjuvant) and metastatic (advanced) disease.

Can Pertuzumab be used alone?

No. Pertuzumab is only approved and effective as part of a combination regimen with trastuzumab and chemotherapy; it is not used as a standalone treatment.

Is Pertuzumab safe during pregnancy?

No. Pertuzumab carries a boxed warning because it can cause serious fetal harm, including fetal death and birth defects. Pregnancy must be ruled out before starting treatment, and effective contraception is required during treatment with Pertuzumab and for at least 7 months afterward. Any suspected pregnancy during treatment should be reported to a physician immediately.

What monitoring is needed while taking Pertuzumab?

Because Pertuzumab, especially combined with trastuzumab, can affect heart function, doctors check heart pumping function (LVEF) before and periodically during treatment. Patients are also observed during and after each infusion of Pertuzumab for infusion-related or allergic reactions, and monitored for diarrhea, which can sometimes be severe.

What are the most common side effects of Pertuzumab?

The most common side effects of Pertuzumab-based treatment include diarrhea, hair loss, nausea, low white blood cell counts, fatigue, and rash. Patients should tell their care team promptly about severe or persistent symptoms.

What happens if a dose of Pertuzumab is missed or delayed?

If less than 6 weeks have passed since the last dose of Pertuzumab, the regular maintenance dose is given as soon as possible. If 6 weeks or more have passed, treatment restarts with the full initial (loading) dose of Pertuzumab before resuming the regular every-3-week schedule. This decision is always made by the treating physician.
