Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is a phase III multi-center, randomized, open-label, parallel control study to evaluate the efficacy and safety of recombinant humanized anti-HER2 monoclonal antibody-Monomethyl auristatin E (MMAE) conjugate for the treatment of HER2-overexpression locally advanced or metastatic gastric cancer. The HER2-overexpression is defined as: the HER2 IHC 3+ or 2+, regardless of FISH status.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • All subjects must have inoperable, advanced or metastatic gastric or or gastroesophageal adenocarcinoma
  • Have had progression or intolerance following receipt of at least two systemic chemotherapy for advanced or metastatic disease.
  • The HER2 IHC test result is IHC 2+ or IHC 3+, the subject's previous test results (confirmed by the investigator) or the research center's test results are acceptable; the subject can provide the Specimen of primary or metastatic tumor for HER2 review/judgment.

  • History of major surgery within 4 weeks of planned start of trial treatment.
  • Has received a live virus vaccine within 4 weeks of planned start of trial treatment.
  • Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
  • History of other malignancy within the previous 5 years, except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, or cancers with a similar curative outcome as those mentioned above.
  • Assessed by the investigator to be unable or unwilling to comply with the requirements of the protocol.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Overall survival (OS)
Time Frame: within approximately 3 years
Overall survival (OS) refers to the time from the date of randomization to the date of death of the subject.
within approximately 3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Progression-free survival (PFS), evaluated by the investigator
Time Frame: within approximately 3 years
Progression-free survival (PFS) refers to the time from the date of randomization to the first researcher's evaluation of disease progression or death (calculated by the event that occurred first). The disease progression will be evaluated by the researchers according to the RECIST 1.1 standard.
within approximately 3 years
Objective remission rate (ORR)
Time Frame: within approximately 3 years
The objective response rate will be mainly analyzed by the independent efficacy evaluation committee according to the RECIST 1.1 standard tumor evaluation (the evaluation by the investigator will also be performed).
within approximately 3 years
Duration of relief (DOR)
Time Frame: within approximately 3 years
DOR is defined as the time from the first documented objective response (CR or PR) to the first documented disease progression or death
within approximately 3 years
Disease control rate (DCR)
Time Frame: within approximately 3 years
Disease control rate (DCR) is defined as cases where objective remission (assessed as complete remission or partial remission according to RECIST 1.1 standard) or stable disease during the study.
within approximately 3 years
Tumor progression time (TTP)
Time Frame: within approximately 3 years
Time to disease progression (TTP) refers to the time from the random date to the first disease progression (calculated by the event that occurred first). Disease progression will be evaluated by the investigator according to the RECIST 1.1 standard (investigator and Independent Review Committee(IRC) evaluation).
within approximately 3 years
