This SC injection is a new formulation of intravenous (IV) trastuzumab.

On February 22, 2019, the FDA approved a new indication for trifluridine plus tipiracil (Lonsurf; Taiho Pharmaceuticals), an oral combination of a nucleoside metabolic inhibitor and a thymidine phosphorylase inhibitor for the treatment of patients with metastatic gastric or gastroesophageal junction adenocarcinoma who received ≥2 lines of chemotherapy regimens with a fluoropyrimidine, a platinum, a taxane or irinotecan, and, if appropriate, HER2/neu-targeted therapy. The FDA used its priority review process for this new indication and granted it an orphan drug designation. Trifluridine plus tipiracil was previously approved for metastatic colorectal cancer.
