What this trial studies

This study evaluates the safety and effectiveness of SY001, a treatment targeting mesothelin in patients with advanced solid tumors, specifically ovarian and pancreatic cancers. It employs a single-arm, dose-increasing design using the '3+3' approach for dose escalation. The study aims to assess pharmacokinetics, cytokine levels, and the correlation between SY001's efficacy and patient outcomes. Participants must have measurable tumor lesions and have previously failed at least one line of treatment.

Who should consider this trial

Good fit: Ideal candidates are patients with advanced ovarian or pancreatic cancer who have failed prior treatments and have tumors that test positive for mesothelin.

Not a fit: Patients who are pregnant, lactating, or have uncontrolled active infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced solid tumors that overexpress mesothelin.

How similar studies have performed: While this approach is novel, similar studies targeting mesothelin have shown promise in other contexts, suggesting potential for success.
