Tirelizumab Combined With Chemotherapy in the Treatment of HER-2 Negative Locally Advanced Gastric Cancer

February 28, 2024 updated by: Lin Chen

Clinical Efficacy and Safety of Tirelizumab Combined With Chemotherapy in the Treatment of HER-2 Negative Locally Advanced Resectable Gastric Cancer

This study objectively analyzes the safety and survival evaluation of perioperative immunotherapy combined with chemotherapy in locally advanced gastric cancer patients through a prospective randomized controlled trial research method; By comparing the pathological response rate, disease-free survival rate, and incidence of adverse events between the combination therapy and chemotherapy alone group, we aim to verify the efficacy and safety of tirelizumab combined with SOX/XELOX chemotherapy in disease control of locally advanced gastric cancer patients, laying the foundation and providing a basis for large-scale multicenter clinical research.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Tirelizumab combined with neoadjuvant chemotherapy

Drug: Tirolizumab+SOX/XELOX
Tirolizumab combined with chemotherapy(SOX/XELOX) regimen. The SOX regimen consists of the drugs Tegilol (S-1) and Oxaliplatin. The XELOX regimen consists of the drugs oxaliplatin and capecitabine.
Active Comparator: standard chemotherapy
Four cycles of standard chemotherapy regimen (SOX/XELOX regimen) were administered before and after surgery.

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
Pathological complete response (pCR)
Time Frame: Less than 20 months
After neoadjuvant therapy, there were no residual surviving tumor cells in the tumor bed during the pathological remission assessment of postoperative specimens.
Less than 20 months
Objective Response Rate（ORR）
Time Frame: Less than 20 months
The proportion of patients whose tumor volume has shrunk to a predetermined value and can maintain the minimum time limit requirement is the sum of complete response (CR) and partial response (PR) ratios, with ORR=CR+PR.
Less than 20 months

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
Disease-free survival（DFS）
Time Frame: Less than 20 months
Time from randomization to disease recurrence or (for any reason) death.
Less than 20 months
Overall survival（OS）
Time Frame: Less than 20 months
Time from randomization to death (for any reason)
Less than 20 months
Major Pathologic Response（MPR）
Time Frame: Less than 20 months
After preoperative treatment, the number of surviving tumors decreases below the threshold that can affect clinical prognosis.
Less than 20 months
The incidence of adverse events during treatment
Time Frame: Less than 20 months
Including adverse reactions related to immunotherapy and postoperative complications. Reflecting safety and tolerability.
Less than 20 months
