Feasibility Study of Intraperitoneal Bevacizumab for Palliation of Intractable Malignant Ascites

Eastern Regional Medical Center

Status and phase: Terminated; Phase 1

Conditions: Malignant Ascites

Treatments: Drug: Intraperitoneal Bevacizumab

Study type: Interventional

Funder types: Other

Identifiers

NCT02496286

EP2014013

Details and patient eligibility

About

This study will evaluate the safety and efficacy of intraperitoneal administration of Bevacizumab to prevent the recurrence of malignant ascites. Ten patients will receive intraperitoneal Bevacizumab 200 mg in 250 ml of normal saline for infusion every two weeks for up to six weeks, or a maximum of three treatments.

Full description

This protocol describes a pilot study to assess whether intraperitoneal Bevacizumab infusion is safe and improves the time to repeat paracentesis. In patients with non-draining malignant peritoneal effusion, published data suggests that the average time to repeat paracentesis in malignant ascites is 10-13 Days. The investigators' treatment will be considered potentially efficacious if the median time to repeat paracentesis is greater than 14 days.

Enrollment: 10 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
