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

Eligibility Criteria

Age21 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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.
