What is Ontruzant?

Ontruzant is an FDA (U.S. Food and Drug Administration) approved medication manufactured by Samsung Bioepis Co., Ltd. Ontruzant is biosimilar to Herceptin (trastuzumab), meaning that the biological product is approved based on data demonstrating that it is highly similar to an FDA-approved biological product, known as a reference product, and that there are no clinically meaningful differences between the biosimilar product and the reference product. Biosimilarity of Ontruzant has been demonstrated for the condition(s) of use (e.g. indication(s), dosing regimen(s)), strength(s), dosage form(s), and route(s) of administration described in its Full Prescribing Information.

Ontruzant is indicated for adjuvant treatment of HER2 overexpressing node positive or node negative (ER/PR negative or with one high risk feature) breast cancer as part of a treatment regimen consisting of doxorubicin, cyclophosphamide, and either paclitaxel or docetaxel, as part of a treatment regimen with docetaxel and carboplatin, as a single agent following multi-modality anthracycline based therapy, in combination with cisplatin and capecitabine or 5-fluorouracil, for the treatment of HER2-positive metastatic gastric or gastroesophageal junction adenocarcinoma who have not received prior treatment for metastatic disease.

Trastuzumab can result in subclinical and clinical cardiac failure manifesting as CHF, and decreased LVEF, with the greatest risk when administered with anthracyclines. Evaluate cardiac function prior to and during treatment. Discontinue Ontruzant for cardiomyopathy, infusion reactions, pulmonary toxicity, anaphylaxis, angioedema, interstitial pneumonitis, or acute respiratory distress syndrome.

What doses of Ontruzant are available?

Ontruzant is available in injection form, in the following doses: 150 mg lyophilized powder in a single-dose vial for reconstitution.

Please read the full prescribing information and always speak with a healthcare professional about any changes to your dose so they can monitor and evaluate your condition.

Ontruzant active ingredients

Ontruzant contains the active ingredient trastuzumab, which is a monoclonal antibody. Trastuzumab is designed to bind selectively to an antigen called human epidermal growth factor receptor 2 (HER2), found in large amounts on the surface of some cancer cells where it stimulates their growth. When Ontruzant binds to HER2 it stops the growth of these cells causing them to die.

The most common side effects of Ontruzant in clinical trials include:
