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

The primary purpose of this single-arm, open-label, single center trial is to evaluate the efficacy and safety of XBI-302 combined with Nivolumab in the treatment of anti-PD-1/L1 resistant gastric cancer.

During treatment period, all eligible subjects will receive XBI-302 with Nivolumab following gut preparation. The imaging evaluation of efficacy will be performed every 6 weeks.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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.

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: XBI-302 + Nivolumab
FMT capsules XBI-302 will be administered orally every two weeks for 12 weeks and then every four weeks for 12 weeks. Nivolumab will be intravenously infused every two weeks for 24 weeks.
Drug: XBI-302 + Nivolumab
After gut preparation, a single dose of FMT will be performed via oral administration. Subsequently, nine combined treatment cycles that composed of anti-PD-1 infusions (Nivolumab at 240 mg, q2w) and additional FMT capsules, and 3 single treatment cycles of anti-PD-1 infusions will be administered.
Other Names:
  • FMT + PD-1 inhibitor

What is the study measuring?
