Analyzing metabolic changes to predict side effects in gastric cancer immunotherapy

Comprehensive Plasma Metabolomic and Lipidomic Profiling for Predictive Modeling and Biomarker Discovery of Immune-Related Adverse Events in PD-1/PD-L1 Inhibitor-Treated Gastric Cancer Patients: A Prospective Cohort Study

Observational Qinghai Red Cross Hospital · NCT06915389

This study is trying to see if changes in blood samples from gastric cancer patients receiving immunotherapy can help predict side effects they might experience from the treatment.

What this trial studies

This observational study investigates the metabolic and lipidomic changes in gastric cancer patients undergoing PD-1/PD-L1 inhibitor therapy. By collecting and analyzing plasma samples before and after treatment, the study aims to identify biomarkers associated with immune-related adverse events (irAEs). The goal is to develop predictive models that can enhance clinical decision-making and personalize treatment strategies for patients. Participants will be matched based on age, sex, and cancer stage to ensure robust comparisons between those who experience irAEs and those who do not.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a confirmed diagnosis of gastric cancer who have not yet received PD-1/PD-L1 inhibitors.

Not a fit: Patients with autoimmune diseases or severe organ dysfunctions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved prediction and management of adverse events in gastric cancer patients receiving immunotherapy.

How similar studies have performed: While similar studies have explored metabolic profiling in cancer therapies, this specific approach focusing on gastric cancer and irAEs is relatively novel.
