Interventions
Single dose, 2mg/kg group: lyophilized powder of Coprelotamab Injection; strength 110mg/bottle; 2 mg/kg for one dose, intravenous infusion, completed for over 90 minutes
Single dose 6mg/kg group: lyophilized powder of Coprelotamab Injection; strength 110mg/bottle; 6 mg/kg for one dose, intravenous infusion, completed for over 90 minutes
Single dose group: lyophilized powder of Trastuzumab Injection; strength 440 mg/bottle; 6 mg/kg for one dose, intravenous infusion, completed for over 90 minutes
Single dose 8mg/kg group: lyophilized powder of Coprelotamab Injection; strength 110mg/bottle; 8mg/kg for one dose, intravenous infusion, completed for over 90 minutes
GB221:Lyophilized powder of Coprelotamab Injection; strength 110mg/bottle; 2mg/kg, the first infusion is completed over 90 minutes. If no serious adverse reaction is observed, the subsequent infusion can be completed over 30 minutes. The administration shall be continued until disease progression or intolerable toxic reactions or ICF withdrawal of subjects. Multiple dose group; Capecitabine:1000mg/kg, orally twice daily (one dose each in the morning and evening; total daily dose of 2000 mg/m2), administration for 2 weeks followed by a 1-week rest period, as a 3-week cycle.
