Pertuza IV Infusion

Pertuzumab is a humanized monoclonal antibody designed to bind to the HER2 receptor and inhibit the ability of HER2 to interact with other HER family members (HER1, HER2, HER3, and HER4) on the surface of cancer cells. The HER signaling pathway plays a role in the formation and growth of numerous cancers, and previous clinical trials of pertuzumab in a single agent setting had suggested clinical activity-including stable disease-in heavily pretreated patients with advanced ovarian and breast cancers.

For intravenous infusion only. Do not administer as an intravenous push or bolus.

HER2 testing: Perform using FDA-approved tests by laboratories with demonstrated proficiency.

The initial Pertuzumab dose is 840 mg administered as a 60-minute intravenous infusion, followed every 3 weeks thereafter by 420 mg administered as a 30 to 60 minute intravenous infusion.

MBC: Administer Pertuzumab, trastuzumab, and docetaxel by intravenous infusion every 3 weeks. 

Neoadjuvant: Administer Pertuzumab, trastuzumab, and chemotherapy by intravenous infusion preoperatively every 3 weeks for 3 to 6 cycles.

Adjuvant: Administer Pertuzumab, trastuzumab, and chemotherapy by intravenous infusion postoperatively every 3 weeks for a total of 1 year (up to 18 cycles).

No drug-drug interactions were observed between Pertuza and trastuzumab, or between Pertuza and docetaxel, paclitaxel, or carboplatin.

Pertuzumab is contraindicated in patients with known hypersensitivity to pertuzumab or to any of its excipients

Females and Males of Reproductive Potential: Verify the pregnancy status of females prior to initiation of Pertuzumab. There is no information regarding the presence of pertuzumab in human milk, the effects on the breastfed infant or the effects on milk production.

Infusion-Related Reactions: Monitor for signs and symptoms. If a significant infusion-associated reaction occurs, slow or interrupt the infusion and administer appropriate medical therapies.

Hypersensitivity Reactions/Anaphylaxis: Monitor for signs and symptoms. If a severe hypersensitivity reaction/anaphylaxis occurs, discontinue the infusion immediately and administer appropriate medical therapies
