Using CSL511 to improve blood coagulation in patients with pseudomyxoma peritonei undergoing surgery

A Phase 3, Single-center, Randomized, Controlled Clinical Study to Investigate the Efficacy of Fibrinogen Concentrate (CSL511) in Subjects With Pseudomyxoma Peritonei Undergoing Cytoreductive Surgery

PHASE3 · CSL Behring · NCT06617897

This study is testing if a new treatment called CSL511 can help patients with pseudomyxoma peritonei manage bleeding better during surgery.

What this trial studies

This phase 3 clinical trial investigates the efficacy and safety of CSL511, a fibrinogen concentrate, in patients with pseudomyxoma peritonei who are undergoing cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy. Participants will be randomly assigned to receive either CSL511 or cryoprecipitate, with a focus on those expected to experience significant intraoperative blood loss. The study aims to determine if CSL511 can effectively manage bleeding during surgery, potentially improving patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older diagnosed with pseudomyxoma peritonei who are at high risk for intraoperative blood loss during cytoreductive surgery.

Not a fit: Patients with confirmed or suspected coagulation disorders or those who have had recent cardiovascular events may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce intraoperative bleeding and improve recovery outcomes for patients undergoing surgery for pseudomyxoma peritonei.

How similar studies have performed: Other studies have shown promise in using fibrinogen concentrates for managing bleeding in surgical settings, suggesting potential success for this approach.
