Participants receive 25mg/kg HLX22 IV every 3 weeks (Q3W) plus trastuzumab (8 mg/kg loading dose, 6 mg/kg maintenance thereafter) IV Q3W in combination with XELOX chemotherapy

Participants receive 15mg/kg HLX22 IV Q3W plus trastuzumab (8 mg/kg loading dose, 6 mg/kg maintenance thereafter) IV Q3W in combination with XELOX chemotherapy

Participants receive placebo IV Q3W plus trastuzumab (8 mg/kg loading dose, 6 mg/kg maintenance thereafter) IV Q3W in combination with XELOX chemotherapy

HLX22

Placebo

The purpose of this study is to evaluate the clinical efficacy and safety of HLX22 in the HER2+ Locally Adanved or Metastatic Gastric Cancer as the first-line therapy.This study consists of three periods, screening period (28 days), treatment period and follow-up period (including safety follow-up, survival follow-up).Subjects can be enrolled into this study only if they meet inclusion criteria and do not meet exclusion criteria. The enrolled subjects will receive an intravenous infusion of HLX22/placebo and SOC(standard of care: Trastuzumab + XELOX) once every 3 weeks until the loss of clinical benefit, death, intolerable toxicity, withdrawal of informed consent or other reasons as specified in the protocol(whichever occurs earlier).

HLX22(25mg/kg) or HLX22(15mg/kg) or placebo will be administered intravenously \[IV\] on day 1 of each 3-week cycle. Trastuzumab (8 mg/kg loading dose, 6 mg/kg maintenance dose) will be administered IV on day 1 of each 3-week cycle. SOC chemotherapy is XELOX (1000 mg/m\^2 capecitabine administered orally twice daily \[BID\] on days 1-14 of each 3-week cycle and 130 mg/m\^2 oxaliplatin administered IV on Day 1 of each 3-week cycle).

Study of HLX22 in Combanition With Trastuzumab and Chemotherapy Versus Placebo in Combination With Trastuzumab and Chemotherapy for Treatment of Locally Advanced or Metastatic Gastric Cancer

A Randomized, Double-blinded，Multicenter，Phase II Clinical Study of HLX22 (Recombinant Humanized Anti-HER2 Monoclonal Antibody Injection) in Combination With Trastuzumab and Chemotherapy (XELOX) Versus Placebo in Combination With Trastuzumab and Chemotherapy (XELOX) for Treatment of Locally Advanced or Metastatic Gastric Cancer (GC)

PFS is defined as the time from randomization to the first documented disease progression per RECIST 1.1 as assessed by IRRC or death due to any cause, whichever occurs first. PFS will be determined for each treatment arm

ORR is defined as the percentage of participants who have a Complete Response (\[CR\], disappearance of all evidence of disease) or Partial Response (\[PR\], regression of measurable disease and no new sites) per RECIST 1.1 as assessed by IRRC. ORR will be determined for each treatment arm.

OS is defined as the time from randomization to death due to any cause. OS will be determined for each treatment arm.

For participants who demonstrate CR or PR, DOR is defined as the time from first response (CR or PR) to subsequent disease progression or death from any cause, whichever occurs first. DOR will be determined for each treatment arm

An AE is any untoward medical occurrence in a participant that is temporally associated with the use of study treatment, whether or not considered related to the study treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study treatment. The number of participants who experience an AE will be reported for each treatment arm.

a single-center, open-label, dose-escalation Phase I clinical trial to evaluate the safety and the tolerability of HLX22 in patients with advanced solid tumors overexpressing HER2 after failure of standard of care.

This study is an open-label and dose escalation study aimed at exploring the safety and MTD of HLX22.

three dose levels are designed for HLX22 in this study: 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 3+3 design to assign doses to the patients, and thereby determine the MTD of HLX22.

Evaluate Safety, Tolerability and Pharmacokinetics of HLX22 in Patients With Advanced Solid Tumors Overexpressing HER2

A Phase I Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Pharmacodynamics of HLX22 Monoclonal Antibody Injection (HER2 Monoclonal Antibody) in Patients With Advanced Solid Tumours Overexpressing HER2

The MTD is the dose with toxicity rate (estimated by isotonic regression) most approximate to the target one (30%).
