Condition(s) targeted: Pericardial Effusion

Intervention: Colchicines (Drug); Placebo (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: French Cardiology Society

Official(s) and/or principal investigator(s):
Philippe Meurin, MD, Principal Investigator, Affiliation: Clinique Les Grands Près - Villeneuve Saint Denis

Summary

Background: The incidence of asymptomatic pericardial effusion is high after cardiac surgery. Objective: To assess whether colchicine is effective in reducing post operative pericardial effusion volume. Design: Multicenter, randomized, double-blind, placebo-controlled study. Intervention : colchicine 1mg vs placebo, once daily for 14 days Setting :10 post operative cardiac rehabilitation centers. Patients: 200 patients at high risk of tamponade because of moderate to large persistent pericardial effusion (grade 2, 3 or 4 on a scale of 0 to 4 measured by echocardiography) more than 7 days after cardiac surgery. Measurements: The main end point will be change in effusion grade after 14 days of treatment. Secondary endpoints include frequency of late cardiac tamponade.

Clinical Details

Official title: Cochicine Treatment for Post- Operative Pericardial Effusion: The POPE 2 Study A Multicenter, Double-blind, Randomized Trial

Study design: Allocation: Randomized, Endpoint Classification: Safety Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: change in effusion grade

Secondary outcome:

frequency of late cardiac tamponade

number of patients with at least a one-grade decrease in the effusion

mean change in the width of the effusion measured in millimeters

evolution of prespecified subgroups

Detailed description: Clinically insignificant pericardial effusion is common after heart surgery with an incidence of 50 % to 85 % a few days after surgery Cardiac tamponade occurs in about 1-2 % of patients who undergo cardiac surgery and may develop slowly without clear-cut clinical signs. Most tamponade occurs more than 7 days after surgery which is a concern because, at that time, patients often have already been discharged from the hospital. No study has ever shown the efficacy any drug for this condition. In particular, we published a study demonstrating the absence of efficacy of a non steroidal anti inflammatory drug (Meurin P, Tabet JY, Thabut G, et al. French Society of Cardiology. Nonsteroidal anti-inflammatory drug treatment for postoperative pericardial effusion: a multicenter randomized, double-blind trial. Ann Intern Med. 2010 Feb2;152(3):137-43) Cochicine is widely used to treat inflammatory pericarditis ; is it efficient to treat post operative pericardial effusions ? this is the question we want to answer to. Design: Multicenter, randomized, double-blind, placebo-controlled study. Intervention : colchicine 1mg vs placebo, once daily for 14 days Setting :10 post operative cardiac rehabilitation centers. Patients: 200 patients at high risk of tamponade because of moderate to large persistent pericardial effusion (grade 2, 3 or 4 on a scale of 0 to 4 measured by echocardiography) more than 7 days after cardiac surgery. Measurements: The main end point will be change in effusion grade after 14 days of treatment. Secondary endpoints include frequency of late cardiac tamponade.
