On 18 January 2019, the FDA approved the Herceptin®-biosimilar Ontruzant® (trastuzumab-dttb, Samsung BioEpis), a HER2/neu receptor antagonist, for patients with HER2-overexpressing (HER2+) breast cancer in the adjuvant and metastatic setting, and in metastatic HER2+ gastric cancer patients. Ontruzant® was approved as biosimilar, not as an interchangeable product.
Safety
Common adverse events (AEs) of Ontruzant® observed in ≥5% patients with HER2+ breast cancer in the adjuvant setting include headache, diarrhoea, nausea, and chills.
Common AEs of Ontruzant® observed in ≥10% patients with HER2+ metastatic breast cancer include fever, chills, headache, infection, congestive heart failure, insomnia, cough, and rash.
Common AEs of Ontruzant® observed in ≥ 10% patients with HER2+ metastatic gastric cancer include neutropenia, diarrhoea, fatigue, anaemia, stomatitis, weight loss, upper respiratory tract infections, fever, thrombocytopenia, mucosal inflammation, nasopharyngitis, and dysgeusia.
Similar to Herceptin®, the Ontruzant®-label includes a ‘Boxed Warning’ to alert healthcare professionals and patients about the increased risks of cardiomyopathy, infusion reactions, pulmonary toxicity, and embryo-foetal toxicity.
