What this trial studies

This clinical trial evaluates the effectiveness, tolerability, and safety of a single intraperitoneal administration of the investigational drug Prospidelong in patients diagnosed with disseminated gastric cancer. The study will enroll 120 patients aged 18 to 75, randomly assigning them to either the treatment group receiving Prospidelong or a comparison group. Participants will undergo daily examinations during hospitalization and follow-up visits to monitor their health and response to the treatment. The trial aims to gather comprehensive data on the drug's impact on this challenging condition.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 75 with gastric cancer that has spread to the peritoneum and a life expectancy of at least six months.

Not a fit: Patients with severe concomitant diseases in a decompensated stage or those with primary multiple malignant tumors may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients suffering from advanced gastric cancer with peritoneal dissemination.

How similar studies have performed: While similar approaches have been explored, the specific use of Prospidelong in this context is novel and has not been extensively tested in prior studies.
