March 8, 2026 updated by: The First Affiliated Hospital with Nanjing Medical University

A Prospective Exploratory Study of SHR-1701 With or Without Apatinib in Combination With Chemotherapy as Neoadjuvant Therapy for Resectable Locally Advanced Gastric or Gastroesophageal Junction Adenocarcinoma

This study is a multicenter, randomized, two-cohort clinical trial to evaluate the efficacy and safety of SHR-1701 with or without apatinib in combined with chemotherapy of neoadjuvant treatment for resectable locally advanced gastric or gastroesophageal junction adenocarcinoma.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Not yet recruiting

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 enroll patients with resectable, locally advanced (cT3-4aN+M0) gastric adenocarcinoma or gastroesophageal junction adenocarcinoma who have not received anticancer therapy. Eligible subjects will be randomized in a 1:1 ratio to one of the two intervention arms. Arm 1：SHR-1701, apatinib, and SOX. Arm2: SHR-1701 and SOX. Arm 1 incorporates a safety run-in phase, during which the first 6 subjects enrolled in this cohort will undergo safety observation.

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.

Secondary Outcome Measures

Secondary Outcome Measures
