Phase I Trial of Intraperitoneal Bevacizumab in Refractory Malignant Ascites

Phase 1

• Conditions: Refractory Malignant Ascites
• Interventions: Drug: bevacizumab

• Registration Number: NCT01852409
• Lead Sponsor: Peking University

Brief Summary

Malignant ascites often has a profound impact on the quality of life of cancer patients. Current treatments,including dietary, medical, and procedural are often temporary and unsatisfactory options in patients approaching the end of life. Intraperitoneal bevacizumab for the palliation of malignant ascites might be a novel choice for refractory malignant ascites.
