What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Rate of pathological complete responses (pCR)

    Percentage of patients with pCR referring to the total number of enrolled and eligible patients, as evaluated centrally by a reference pathologist.

    Measured: From enrollment to surgery after pre-operative treatment (up to approximately 36 months)

Secondary outcomes (3)
  1. Overall survival

    Overall survival (OS) will be determined by measuring the time interval from enrollment to the end of follow up or death from any cause

    Measured: From enrollment to the end of follow up or death from any cause (up to approximately 60 months)

  2. Progression-free survival

    Progression-free survival (PFS) will be defined as the time from enrollment to the end of follow up or the time of disease progression or relapse or death from any cause

    Measured: From enrollment to the end of follow up or the time of disease progression or relapse or death from any cause (up to approximately 60 months)

  3. The incidences and types of adverse events (AE) and severe adverse events (SAE)

    The incidences and types of adverse events that occur during treatment will be evaluated according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0

    Measured: From enrollment to 90-day after the last dose administration (up to approximately 27 months)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing S1, Oxaliplatin and Serplulimab in people with Adenocarcinoma of the Stomach and Adenocarcinoma of Esophagogastric Junction, run by Yu jiren at 5 sites in China.

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 14 inclusion and 17 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 17 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in China. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 Jiren Yu (+86-0571-87236147, yujr0909@zju.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate of pathological complete responses (pCR) (time frame: From enrollment to surgery after pre-operative treatment (up to approximately 36 months)). 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 17 Jan 2024.
