Zanidatamab‑hrii is a humanized, IgG-like, bispecific HER2-directed antibody. Zanidatamab‑hrii is produced in Chinese hamster ovary cells via recombinant DNA technology and has a molecular weight of 124.8 kDa. ZIIHERA (zanidatamab‑hrii) for injection is supplied as a sterile, preservative free, white lyophilized powder that requires reconstitution and dilution for intravenous use. Each single-dose vial of reconstituted product contains 300 mg of zanidatamab‑hrii and the inactive ingredients: polysorbate 20 (0.63 mg), sodium succinate (4.3 mg), succinic acid (4.3 mg), and sucrose (567 mg).

The resulting solution is diluted and administered by intravenous infusion.
