About this study
Official title: A Randomized, Double-blinded, Multicenter, Phase Ⅲ Clinical Study of HLX22 (Recombinant Humanized Anti-HER2 Monoclonal Antibody Injection) in Combination With Trastuzumab and Chemotherapy (XELOX) Versus Trastuzumab and Chemotherapy (XELOX) With or Without Pembrolizumab for the First Line Treatment of Locally Advanced or Metastatic Gastroesophageal Junction and Gastric Cancer
This is a double-blind, randomized, multiregion, comparative phase Ⅲ clinical study designed to evaluate the efficacy and safety of HLX22 in combination with trastuzumab and chemotherapy as first-line treatment in patients with HER2-positive locally advanced/metastatic adenocarcinoma of the gastric and/or gastroesophageal junction (G/GEJ).Eligible subjects will be randomized to the two groups based on a 1:1 ratio. Enrolled subjects shall be treated with the study drug until the loss of clinical benefit, death, intolerable toxicity, withdrawal of informed consent, or other reasons specified by the protocol (whichever occurs first).
Read the detailed description
In experimental group: HLX22 (15 mg/kg) + trastuzumab + chemotherapy (XELOX) ± placebo (for pembrolizumab), once every 3 weeks (Q3W).
In control group: Placebo (for HLX22) + trastuzumab + chemotherapy (XELOX) ± pembrolizumab, Q3W.
- Conditions
- Gastroesophageal-junction Cancer, Monoclonal Antibody, Gastric Cancer, HER2-positive Gastric Cancer
- Being tested

What is being measured
The primary outcome is the main question the study is designed to answer.
Progression-Free Survival (PFS)per RECIST 1.1 assessed by IRRC(Independent Radiology Review Committee)
PFS is defined as the time from randomization to the first documented disease progression per RECIST 1.1 or death due to any cause, whichever occurs first. PFS will be determined for each treatment arm
Measured: Up to 5 years
Overall Survival (OS)
OS is defined as the time from randomization to death due to any cause. OS will be determined for each treatment arm.
Measured: Up to 5 years
Secondary outcomes (3)
PFS per RECIST 1.1 assessed by investigator
PFS is defined as the time from randomization to the first documented disease progression per RECIST 1.1 or death due to any cause, whichever occurs first. PFS will be determined for each treatment arm
Measured: Up to 5 years
Objective Response Rate (ORR) assessed by IRRC and investigator per RECIST v1.1
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. ORR will be determined for each treatment arm.
Measured: Up to 5 years
Adverse events (AE)
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.
Measured: Up to 5 years

- With histologically or cytologically confirmed diagnosis of previously untreated, locally advanced unresectable or metastatic HER2-positive gastric or gastroesophageal junction adenocarcinoma.
- Had measurable disease as assessed by IRRC according to the RECIST v1.1, the target lesion must not be a bone metastatic lesion only.
- HER2-positive tumor defined as either IHC 3+ or IHC 2+ in combination with ISH+ or FISH, as assessed by a central laboratory on a primary or metastatic tumor.
- ECOG PS within 7 days before randomization: 0-1.
Key exclusion criteria (7 listed)
- Patients with other malignant tumors within 2 years before the randomization.
- Evidence of disease progression within 6 months (before randomization) after completion of prior neoadjuvant or adjuvant chemotherapy (or both) or radiotherapy for gastric adenocarcinoma or gastroesophageal junction adenocarcinoma.
- Previous treatment with any HER2-target therapy.
- Active gastrointestinal bleeding
- Presence of central nervous system (CNS) metastases.
Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.

Primary outcome
Progression-Free Survival (PFS)per RECIST 1.1 assessed by IRRC(Independent Radiology Review Committee)
Time frame: Up to 5 years
PFS is defined as the time from randomization to the first documented disease progression per RECIST 1.1 or death due to any cause, whichever occurs first. PFS will be determined for each treatment arm
Overall Survival (OS)
Time frame: Up to 5 years
OS is defined as the time from randomization to death due to any cause. OS will be determined for each treatment arm.
3 secondary outcomes
PFS per RECIST 1.1 assessed by investigator
Time frame: Up to 5 years
Objective Response Rate (ORR) assessed by IRRC and investigator per RECIST v1.1
Time frame: Up to 5 years
Adverse events (AE)
Time frame: Up to 5 years
Results and safety
This study is still under way. Results are not available in the source record yet.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing HLX22, Pembrolizumab and Trastuzumab in people with Gastroesophageal-junction Cancer and Monoclonal Antibody, run by Shanghai Henlius Biotech at 208 sites in 17 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 27 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 208 sites in China, United States, Japan, Argentina, Turkey (Türkiye) and 12 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Ying Li (+86 18810366427, ying_li1@henlius.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression-Free Survival (PFS)per RECIST 1.1 assessed by IRRC(Independent Radiology Review Committee) (time frame: Up to 5 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Feb 2026.
