Trial Summary

What is the purpose of this trial?

This study will evaluate the impact of colchicine on the change in coronary flow reserve (CFR), a marker for coronary microvascular dysfunction (CMD), compared to placebo in patients with heart failure and ejection fraction above 40% (including patients with improved EF).

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it does exclude those currently taking colchicine for other conditions. It's best to discuss your specific medications with the study team.

What data supports the effectiveness of the drug colchicine for heart failure?

A study tested colchicine for 6 months in patients with stable chronic heart failure and found it helped improve their functional status, suggesting it may be beneficial for heart failure. ^{1 2 3 4 5}

Is colchicine generally safe for use in humans?

Colchicine is generally considered safe for use in humans, especially at low doses, but it may cause gastrointestinal issues like stomach upset. It has been used safely for conditions like coronary artery disease and pericarditis, though some people may experience side effects, so it's important to follow dosing instructions and consult with a doctor. ^{6 7 8 9 10}

How is the drug colchicine unique for treating heart failure?

Colchicine is unique for heart failure treatment due to its anti-inflammatory properties, which are not common in other heart failure medications. It works by affecting white blood cells and reducing inflammation, which may help in conditions like heart failure that involve chronic low-grade inflammation. ^{8 11 12 13 14}

Eligibility Criteria

This trial is for patients with heart failure who still have a decent amount of blood leaving the heart each time it pumps (ejection fraction over 40%). It's also for those whose ejection fraction has gotten better over time. People can't join if they're already on certain medications or have health conditions that could interfere with the study.

Inclusion Criteria

Evidence of pathological systemic inflammation: high C-reactive protein, hs-CRP levels (hs-CRP > or = 5mg/L)

My heart condition limits my physical activity but I can still walk.

I have heart failure with an LVEF over 40% and have been hospitalized or have high NTproBNP levels.

Exclusion Criteria

Treatment Details

Interventions

• Colchicine

Trial Overview The trial is testing whether Colchicine, at a dose of 0.5 milligrams, can improve how well small blood vessels in the heart work compared to a placebo. The main thing being measured is the coronary flow reserve which tells us about these tiny vessels' health.

Participant Groups

Group I: COLCHICINE Active Control 1 Intervention

Patients will be randomly assigned in a 1:1 ratio to receive colchicine 0.5 mg daily or a matched placebo.

Group II: PLACEBO Placebo Group 1 Intervention

Patients will be randomly assigned in a 1:1 ratio to receive colchicine 0.5 mg daily or a matched placebo.

Colchicine is already approved in United States for the following indications:

Approved in United States as Colcrys for:

Findings from Research

In a study of 12 patients with chronic heart failure, nisoldipine significantly improved cardiac index and reduced mean arterial pressure and systemic vascular resistance after acute administration, indicating its potential to enhance heart function.

The hemodynamic effects of nisoldipine peaked one hour after administration and lasted for up to six hours, suggesting it may provide short-term relief in heart failure symptoms without significantly affecting right atrial and pulmonary pressures.

ACE inhibitors are effective in reducing both morbidity and mortality in patients with chronic heart failure (CHF), and they may also help prevent the progression to overt CHF in those with asymptomatic left ventricular dysfunction.

The review provides guidelines for the use of ACE inhibitors in both hospital and general practice settings, while also addressing the role of digoxin and the management of related conditions like angina and arrhythmias in CHF patients.

The Impact-Reco programme analyzed prescription rates of heart failure medications in nearly 4,000 stable outpatients, revealing significant increases in the use of angiotensin receptor blockers and beta-blockers, indicating improved treatment practices over time.

Despite these improvements, the study highlighted that certain patient subgroups, particularly the elderly and those with renal failure, still received suboptimal doses of medications, suggesting a need for further enhancements in treatment strategies.

In a study of 25 patients with mild to moderate heart failure, treatment with lacidipine significantly improved key measures of heart function, including peak oxygen consumption and cardiac index, over an 8-week period.

Lacidipine also reduced systemic vascular resistance, suggesting it may help improve blood flow in heart failure patients, making it a potential adjunct therapy alongside standard treatments.

In a study of 267 patients with stable chronic heart failure, colchicine treatment significantly reduced inflammation markers like C-reactive protein and interleukin-6, indicating its anti-inflammatory effects.

However, colchicine did not lead to significant improvements in functional status or exercise tolerance, nor did it reduce the risk of death or hospital stays compared to placebo.

Colchicine, an ancient drug, is gaining attention for its potential benefits in treating cardiovascular diseases, as highlighted by recent studies up to October 2016.

It is crucial for healthcare professionals to understand both the therapeutic advantages and the risks, including side effects and drug interactions, associated with colchicine in cardiac care.

In a multicenter trial involving 240 patients with multiple recurrences of pericarditis, colchicine significantly reduced the rate of recurrent pericarditis compared to placebo, with only 21.6% of patients in the colchicine group experiencing recurrences versus 42.5% in the placebo group (p=0.0009).

Colchicine was found to have a similar safety profile to placebo, with no serious adverse events reported, suggesting it can be safely added to conventional anti-inflammatory treatments for managing recurrent pericarditis.

Colchicine has emerged as a promising treatment in cardiovascular disease due to its unique anti-inflammatory mechanism, making it safer than most current anti-inflammatory drugs for patients with heart conditions.

While colchicine is well-established for acute inflammatory conditions like pericarditis, its potential benefits in chronic conditions such as coronary artery disease and heart failure are still being explored, indicating a need for further research in these areas.
