Is this trial a fit for you?

Likely a 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.

Probably not a fit

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

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.

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