Intervention

Drug:
TRASTUZUMAB BS
Regimen A or regimen B is used for HER2-overexpressing breast cancer. RegimenB is used for HER2-overexpressing unresectable advanced or recurrent gastric cancer in combination with other anti tumor agent(s). Regimen A: The recommended dose for trastuzumab (genetical recombination) [Trastuzumab Biosimilar 3] in adult patients is 4 mg/kg (weight) at initial dose and 2 mg/kg after the second dose, in both of them, by IV drip infusion over 90 minutes once daily every week. Regimen B: The recommended dose for trastuzumab (genetical recombination) [Trastuzumab Biosimilar 3] in adult patients is 8 mg/kg (weight) at initial dose and 6 mg/kg after the second dose, in both of them, by IV drip infusion over 90 minutes once daily every 3 weeks. If the initial dose is well tolerated, the dosing time after the second dose can be shortened up to 30 minutes.
