HLX05

Intervention Type: DRUG

A single dose of 250 mg/m2 HLX05 will be given by intravenous drip over 2 h (± 10 min). Antihistamines (e.g., diphenhydramine 20 mg or promethazine 25 mg by intramuscular injection within 30 min prior to dosing) and corticosteroids (e.g., dexamethasone 5 mg by intravenous bolus within 30 min prior to dosing) will be given prior to infusion.

US-sourced Erbitux®

Group Type: ACTIVE_COMPARATOR

US-Erbitux®

Intervention Type: DRUG

A single dose of 250 mg/m2 US-Erbitux® injection will be given by intravenous drip over 2 h (± 10 min). Antihistamines (e.g., diphenhydramine 20 mg or promethazine 25 mg by intramuscular injection within 30 min prior to dosing) and corticosteroids (e.g., dexamethasone 5 mg by intravenous bolus within 30 min prior to dosing) will be given prior to infusion.

CN-sourced Erbitux®

Group Type: ACTIVE_COMPARATOR

CN-Erbitux®

Intervention Type: DRUG

A single dose of 250 mg/m2 US-Erbitux® injection will be given by intravenous drip over 2 h (± 10 min). Antihistamines (e.g., diphenhydramine 20 mg or promethazine 25 mg by intramuscular injection within 30 min prior to dosing) and corticosteroids (e.g., dexamethasone 5 mg by intravenous bolus within 30 min prior to dosing) will be given prior to infusion.

EU-sourced Erbitux®

Group Type: ACTIVE_COMPARATOR

EU-Erbitux®

Intervention Type: DRUG

A single dose of 250 mg/m2 EU-Erbitux® injection will be given by intravenous drip over 2 h (± 10 min). Antihistamines (e.g., diphenhydramine 20 mg or promethazine 25 mg by intramuscular injection within 30 min prior to dosing) and corticosteroids (e.g., dexamethasone 5 mg by intravenous bolus within 30 min prior to dosing) will be given prior to infusion.
