Stratification marker for immunotherapy in gastric or esphageal cancer

JRCT ID: jRCT1031200386

Registered date:01/03/2021

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: gastric cancer, esophageal cancer
• Date of first enrollment: 28/04/2021
• Target sample size: 150
• Study type: Observational

Outcome(s)

• Primary Outcome: Multivariate discriminant models created by combination of plasma amino acid and/or metabolite concentrations, which are useful for predicting overall survival in patients treated with anti-PD-1/PL-L1 antibody
• Secondary Outcome: Multivariate discriminant models created by combination of plasma amino acid and/or metabolite concentrations, which are useful for predicting progression free survival in patients treated with anti-PD-1/PL-L1 antibody

Key inclusion & exclusion criteria

• Age minimum: >= 20age old
• Age maximum: Not applicable
• Gender: Both

Include criteria

1) Patients with pathologically or cytologically diagnosed, advanced or recurrent, gastric or esphageal cancer, who are treated with anti-PD-1/PL-L1 antibody (measurable target lesions for response evaluation are not required).
2) Patients over 20 years old with written informed consent
3) Patients with ECOG PS 0-2

Exclude criteria

1) Patients with the past history of immunological treatments (immune checkpoint inhibitors, cancer vaccines, or immune cell therapies)
2) Patients with regular use of amino acid formulations (asintravenous or enteral nutrition) or supplements
3) Patients with presumed abnormalities of amino acid metabolism, such as liver cirrhosis, renal failure, inborn error of amino acid metabolism, pregnancy, and feeding
4) Patients enrolled in other clinical trials for pharmaceuticals or medical devices
5) Patients with active double cancer [synchronic double cancer or asynchronous double cancer with no more than 5-year disease-free period, excluding carcinoma in situ (lesions equal to intraepithelial or intramucosal cancer) judged to have been cured by local treatment]
6) Patients with other inappropriate conditions for enrollment judged by the clinicians
