Study summary

There has not been a prospective, randomized controlled trial of colchicine to reduce post-AF ablation pericarditis in an era of newer AF ablation techniques. The hypothesis is that an empiric pre and post AF ablation treatment protocol with colchicine may reduce the incidence and symptom severity of post-AF ablation related pericarditis. Thus, the goal of this study is to

  1. Identify the incidence of post-AF ablation related pericarditis in patients undergoing ablation via high power, short duration strategy (shorter total RF time, but increased stability due to steerable catheters and possible difference from resistive vs conductive heating).
  2. Identify potential differences in patients undergoing PVI only versus PVI + additional ablation
  3. Identify whether patients on who are already on anti-inflammatories such as ASA or statins have a lower incidence than those without
  4. Determine if an empiric treatment strategy with colchicine (for 7 days post ablation) reduces the incidence of post-operative AF
Read the detailed description

This study will be a prospective, randomized controlled study of 248 patients presenting to the electrophysiology lab at Ascension St. Vincent (Indianapolis, IN) and Ascension Sacred Heart (Pensacola, FL) for atrial fibrillation ablation. Cases will be randomized in sequential order.

The control arm will undergo standard of care, whereas the study arm will undergo treatment with colchicine 0.6mg PO BID for 7 days following ablation.

Study variables will consist of

  • Patient demographics

    o age, gender, comorbidities (HTN, HLD, DM-2, COPD, tobacco use, OSA, CKD, weight in kg, BMI, LVEF, autoimmune inflammatory condition such as RA), type of AF (paroxysmal, persistent, etc.)

  • Medical therapy characteristics

    o anticoagulation choice, statin present, aspirin present, discontinuation of colchicine due to gastrointestinal distress

  • Procedural characteristics o length of procedure, initial vs redo procedure, PVI only versus PVI + additional lines, total RF application time, HPSD vs MPMD approach, #RF applications, Power, Contact force, Impedance

Rates of acute post-operative pericarditis will be compared between the two groups. Subjects will be called by study personnel within 7-14 days to identify any post-ablation symptoms. If a patient develops pericarditis, standard anti-inflammatory therapy will be initiated in those patients regardless of study arm.

The primary outcome will be the development of post-AF ablation pericarditis within 30 days of ablation. This will be ascertained by comprehensive chart review and at the routine post-ablation follow up visit; additionally, there will be a standard telephone survey administered 7-14d after ablation (see instrument). Secondary outcomes will include symptoms, incidence of post-ablation AF recurrence, patient satisfaction using a Likert scale, and other clinical variables.

Inclusion criteria

  • All patients >/= 18 undergoing atrial fibrillation ablation

Exclusion criteria

Exclusion Criteria:

  • Patients unable to receive or tolerate colchicine
  • Pregnant or lactating women
  • Concomitant use of drugs interacting with colchicine (including: cyclosporin, ranolazine, tacrolimus, clarithromycin, indinavir, itraconazole, ketoconazole, nefazadone, ritonavir, saquinavir, suboxone, telithromycin, erythromycin, fluconazole, verapamil, diltiazem, or more than 1 glass grapefruit juice daily)
  • Severe renal impairment ( \< 30 mL/min)
  • Severe hepatic impairment (/AST greater than 5x or clinical cirrhosis)
  • Ongoing current use of colchicine.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

What researchers measure

Primary outcomes

  1. Proportion of patients with Pericarditis

    Clinical pericarditis ascertained by comprehensive chart review and a follow up phone call using a survey instrument.

    Time frame: Postoperative day 30.

Secondary outcomes

  1. Proportion of patients with recurrent Atrial fibrillation

    Recurrence of atrial fibrillation post ablation

    Time frame: Through study completion, an average of 1 year

  2. Median rating of patient satisfaction on a Likert scale, comparing the study group and standard of care group.

    Patient satisfaction with ablation and post ablation care, measured on a Likert scale (min 1 and max 5, with 1 being best and 5 being worst) and derived from a telephone survey.

    Time frame: Postoperative day 14

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 8, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
