What is Kanjinti?

Kanjinti is an FDA (U.S. Food and Drug Administration) approved medication manufactured by Amgen Inc. It 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.

Trastuzumab targets HER2-expressing breast cancer cells in cancer patients and is indicated:

  • For the 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, or as a single agent following multi-modality anthracycline-based therapy
  • For cancer treatment of adult patients with HER2 positive early breast cancer (EBC), in combination with paclitaxel for first-line treatment of HER2-overexpressing metastatic breast cancer, or as a single agent for the treatment of HER2-overexpressing breast cancer in patients who have received one or more chemotherapy regimens for metastatic disease
  • In combination with cisplatin and capecitabine or 5-fluorouracil, for the treatment of patients with HER2 overexpressing metastatic gastric cancer or gastroesophageal junction adenocarcinoma who have not received prior treatment for metastatic disease

Trastuzumab products can result in subclinical and clinical cardiac failure manifesting as CHF, and decreased LVEF, with the greatest risk when administered with anthracyclines.

Evaluation of cardiac function before and during treatment should be carried out. Discontinue Kanjinti for cardiomyopathy, infusion reactions, pulmonary toxicity, anaphylaxis, angioedema, interstitial pneumonitis, or acute respiratory distress syndrome.

What doses of Kanjinti are available?

Kanjinti is available in injection form, in the following doses: 420 mg lyophilized powder in a multiple-dose vial for reconstitution.

Your dose of Kanjinti will be based on your condition being treated as well as your body weight. Always speak with a healthcare professional about any changes to your dose so they can monitor and evaluate your condition.
