Brief Summary
Colchicine will lower C-reactive protein (CRP) in chronic atrial fibrillation and reduce the rise in CRP which occurs following atrial fibrillation ablation

Outcome Measures
Primary Outcomes (1)
Change in C-reactive Protein
Plasma levels of C-reactive protein was determined by the immunoprecipitation method using an in vitro diagnostic assay.
baseline, day 28
Secondary Outcomes (2)
Number of Subjects With Atrial Fibrillation
day 28
Time Course of C-reactive Protein Levels
baseline, day 3, day 7, day 14, day 28
Study Arms (6)
Chronic atrial fibrillation, colchicine
ACTIVE COMPARATORColchicine 0.6 mg PO BID. Subjects not undergoing ablation.
Chronic atrial fibrillation, placebo
PLACEBO COMPARATORMatching placebo. Subjects not undergoing ablation.
Pre-ablation, sinus rhythm, colchicine
ACTIVE COMPARATORColchicine 0.6 mg PO BID. Subjects undergoing ablation.
Pre-ablation, sinus rhythm, placebo
PLACEBO COMPARATORMatching placebo. Subjects undergoing ablation.
Pre-ablation, AF, colchicine
ACTIVE COMPARATORColchicine 0.6 mg PO BID. Subjects undergoing ablation.
Pre-ablation, AF, placebo
PLACEBO COMPARATORMatching placebo. Subjects undergoing ablation.
Interventions
Colchicine tablets will be over-encapsulated by the research pharmacy to be indistinguishable from placebo
Matching placebo tablets will be encapsulated by the research pharmacy to be indistinguishable from active drug
Eligibility Criteria
You may qualify if:
- Group 1: Persistent or chronic AF presenting for evaluation in cardiology offices. Diagnosis of AF will be made based on the 12 -lead surface ECG.
- Group 2: Paroxysmal AF scheduled to go AF ablation presenting to the electrophysiology laboratory for the procedure in sinus rhythm..
- Group 3:Chronic AF scheduled to go clinically indicated AF ablation, and presenting in the electrophysiology laboratory in atrial fibrillation .
You may not qualify if:
- Abnormal liver function with elevated enzymes\> 1.5 times the normal.
- Abnormal kidney function with glomerular filtration rate \< 50 ml/min
- Increased levels of creatine kinase or known myopathy
- Neutropenia
- Known GI disorders
- Women of childbearing age who have not had surgical sterilization and are not using oral contraceptives, or who's spouse has not had surgical sterilization will be excluded due to the length of the trial and the possibility that they could become pregnant after entry.
- Pregnant and lactating women
- Lactose intolerance
- Known sensitivity, allergy, or contraindication to colchicine use

Limitations and Caveats
Enrollment was halted in 2015 due to departure of study staff; shortly thereafter Takeda Inc announced it could not renew production of colchicine nor support the study after the end of 2016. Principal investigator elected to terminate enrollment.
