About this study

Official title: The Role of Colchicine as Anti-Inflammatory Treatment in Patients With HFpEF: A Prospective Study

Heart failure with preserved ejection fraction (HFpEF) is a condition associated with high morbidity and mortality. Chronic low-grade inflammation plays a key role in its progression, yet few treatments specifically target this pathway.

This clinical trial aims to evaluate the effectiveness of colchicine, a well-tolerated anti-inflammatory drug, in reducing inflammation in HFpEF patients. The study will assess whether colchicine lowers levels of soluble ST2 (sST2), a biomarker linked to inflammation and cardiac stress in HFpEF.

Participants will take colchicine daily for three months, with blood samples collected at baseline and at the end of the study to measure changes in sST2 levels. The findings could provide new insights into the potential role of colchicine as a treatment for HFpEF.

Read the detailed description

Heart failure with preserved ejection fraction (HFpEF) is a complex condition associated with high morbidity and mortality. While its exact causes remain unclear, low-grade systemic inflammation plays a key role by promoting myocardial fibrosis and increasing heart muscle stiffness. Despite this, anti-inflammatory treatments for HFpEF remain largely unexplored.

Colchicine is a well-established anti-inflammatory drug that blocks key inflammatory pathways, including inflammasome activation and the release of interleukin-1 (IL-1). It has demonstrated cardiovascular benefits in trials such as COLCOT and LoDoCo2, significantly reducing the risk of heart-related events in coronary artery disease. However, its effects in HFpEF patients are not yet known.

Two important biomarkers-soluble suppression of tumorigenicity 2 (sST2) and high-sensitivity C-reactive protein (hsCRP)-are strongly linked to worse outcomes in HFpEF. Elevated sST2 reflects increased fibrosis and cardiac stress, while high hsCRP indicates systemic inflammation. Both markers are associated with more severe symptoms and a higher risk of complications. Additionally, the 6-minute walk test (6MWT) is a widely used measure of physical function and exercise capacity in heart failure patients.

This single-center, prospective clinical trial aims to evaluate the effects of colchicine in HFpEF patients with elevated inflammation. Participants will receive colchicine for three months, with assessments of sST2, hsCRP, and 6MWT performance before and after treatment. Findings from this study may provide valuable insights into whether colchicine can reduce inflammation and improve functional capacity in HFpEF patients.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Colchicine Tablets in people with HFpEF - Heart Failure With Preserved Ejection Fraction, run by Cairo University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 25 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Soluble Suppression of Tumourigenicity 2 (sST2,ng/ml) (time frame: From baseline to 12 weeks post-treatment initiation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Feb 2025.
