A Phase 2 interventional study of Colchicine in Atrial Fibrillation, Catheter Ablation and Pericarditis, sponsored by St. Vincent Cardiovascular Research Institute. Completed at 1 site in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-12-12.

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
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
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.

Exclusion Criteria:
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.
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.
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.
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.

Proportion of patients with Pericarditis
Clinical pericarditis ascertained by comprehensive chart review and a follow up phone call using a survey instrument.

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

Ran from May 2021 to primary completion in Jan 2022, 8 months.
Of 41 phase 2 interventional studies under Atrial Fibrillation, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 18 and three quarters within 39. This study's 8 months is below that.
