The Preferred Premedication Order to Prevent Infusion Reactions in Patients with Breast Cancer Receiving Pertuzumab Plus Trastuzumab and Docetaxel

Abstract

Aims:Pertuzumab plus trastuzumab and docetaxel is a standard regimen for human epidermal growth factor receptor 2 (HER2)-positive breast cancer in the metastatic, adjuvant, and neoadjuvant settings. Infusion reaction represents one of the common side effects of anti-HER2 agents. There is no standard premedication to prevent infusion reactions, although antihistamines, acetaminophen, and/or corticosteroids are often used for this purpose. This study evaluated the ability of premedication to prevent induction reactions in patients receiving pertuzumab, trastuzumab, and docetaxel. Methods: This retrospective, single-institute study assessed infusion reactions in 72 women with HER2-positive early breast cancer who received pertuzumab, trastuzumab, and docetaxel between November 2018 and April 2021. Thirty-six patients received premedication consisting of oral acetaminophen prior to pertuzumab and trastuzumab administration and dexamethasone and D-chlorpheniramine maleate intravenously prior to docetaxel administration (previous regimen). Thirty-six patients received premedication consisting of acetaminophen, dexamethasone, and D-chlorpheniramine maleate sequentially prior to pertuzumab, trastuzumab, and docetaxel administration (current regimen). Results: The rates of infusion reaction after the initial injection were 55.6 and 16.7% in the previous and current regiment groups, respectively (p = 0.001). Trastuzumab more frequently caused infusion reactions than pertuzumab and docetaxel. Chills, vomiting, and nausea were the major symptoms of infusion reactions. Conclusion: Premedication featuring the upfront use of dexamethasone and D-chlorpheniramine maleate prior to the administration of anti-HER2 targeted agents significantly prevented infusion reactions.
