Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients with advanced unresectable gastric or gastroesophageal junction adenocarcinoma who meet specific health criteria.

Probably not a fit

Patients with serious systemic dysfunction or those who cannot tolerate chemotherapy may not benefit from this study.

What this trial studies

This phase I/II study aims to evaluate the safety and efficacy of a combination treatment involving Irinotecan, Paclitaxel, and Tislelizumab in patients with advanced unresectable gastric cancer. The study will assess the tolerability of this regimen in patients with histologically confirmed adenocarcinoma of the stomach or gastroesophageal junction. Participants will be monitored for their performance status and various health parameters to ensure they can tolerate the chemotherapy involved in the treatment.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced gastric cancer, potentially improving survival rates.

How similar studies have gone: Other studies have explored similar combinations of chemotherapy and immunotherapy, showing promising results, but this specific combination is novel.
