|Condition or disease||Intervention/treatment||Phase|
|Solid Tumor||Drug: HLX22||Phase 1|
This study is an open-label and dose escalation study aimed at exploring the safety and MTD of HLX22.
Four dose levels are designed for HLX22 in this study: 1, 3, 10, and 25 mg/kg/3 weeks. The 3 mg/kg/3 weeks will serve as the starting dose. The study will use a BOIN design to assign doses to the patients, and thereby determine the MTD of HLX22.

Experimental: HLX22 group
HLX22, at four dose levels (1, 3, 10, 25mg/kg), to be intravenously injected once every three weeks; Study drugs given until disease progression, one year of treatment, withdrawal from the study or death
Humanized Anti-Human Epidermal Growth Factor Receptor-2 Monoclonal Antibody
Other Name: HER2 Monoclonal Antibody
- Maximum Tolerated Dose (MTD) of HLX22 in patients with advanced solid tumors overexpressing HER2 [ Time Frame: from day1 to day 42(cycle 1 and cycle2 ,each cycle is 21days) ]The MTD is the dose with toxicity rate (estimated by isotonic regression) most approximate to the target one (30%).
- the pharmacokinetic characteristics of HLX22 at different doses in patients. [ Time Frame: cycle1 to cycle 8 ,and 28-day follow-up visit after the last infusion (if possible),(each cycle is 21 days). ]Area under the plasma concentration versus time curve (AUC) for single dose and multiple doses
- the pharmacodynamic characteristics of HLX22 at different doses in patients [ Time Frame: cycle 1 to cycle 6 (each cycle is 21 days) ]the concentration of soluble HER1 and HER2 in serum
- the immunogenicity of HLX22 in humans [ Time Frame: cycle 1 to cycle 6 (each cycle is 21 days) ]anti-HLX22 antibodies in serum
