What this trial studies

This study aims to evaluate the effectiveness and safety of administering ondansetron either weekly or every three weeks to prevent nausea and vomiting in patients undergoing chemotherapy combined with PD-1 blockade. Given that nausea and vomiting are significant side effects of chemotherapy, the study seeks to determine which dosing schedule provides better control of these symptoms. Participants will be randomly assigned to receive one of the two treatment regimens, and their responses will be monitored to assess the outcomes. The findings may lead to improved management strategies for patients experiencing these adverse effects.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with confirmed malignant solid tumors scheduled to receive cisplatin-based chemotherapy combined with PD-1 blockade.

Not a fit: Patients whose nausea or vomiting is caused by factors other than chemotherapy and PD-1 blockade may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the quality of life for patients undergoing chemotherapy by providing more effective prevention of nausea and vomiting.

How similar studies have performed: Previous studies have shown success in managing chemotherapy-induced nausea and vomiting, suggesting that this approach may also yield beneficial results.
