Safety and Efficacy of LOw DOse COlchicine in Patients With STatin INTolerance: the LODOCO STINT Pilot Study

Phase 1

Recruiting

• Conditions: Statin Adverse Reaction
• Interventions: Drug: Low-dose colchicine at 0.5mg daily; Other: Placebo

• Registration Number: NCT06874192
• Lead Sponsor: Virginia Commonwealth University

Brief Summary

Statins are a class of cholesterol lowering medications that contribute to reducing a person's risk of experiencing a cardiovascular event like heart attack. Along with the ability to lower cholesterol, statins also possess anti-inflammatory properties which contribute to their cardioprotective effects. Some people experience side effects while taking statins and are unable to continue treatment with them,which can then increase a person's risk of having cardiovascular issues due to untreated high cholesterol levels. Prior studies have shown that inflammation in the body may lead to an increased risk of a future cardiovascular events. Low dose colchicine (LODOCO), an anti-inflammatory agent, has been shown to reduce cardiovascular events by inhibiting inflammation, a major cause of cardiovascular disease. The United States Food and Drug Administration (FDA) has approved LODOCO to reduce the risk of a future cardiac events for those who have existing heart disease or possess multiple risk factors for heart disease.

Detailed Description

This study will test the effects of LODOCO in those who have previously been identified as statin intolerant, meaning they are unable to continue taking statins because of side effects. The primary objective of this study is to evaluate the safety and efficacy of low-dose colchicine (LODOCO) in subjects with statin intolerance. Safety will be assessed by monitoring the incidence of adverse events from baseline to four weeks. Efficacy will be determined by measuring the change in high-sensitivity C-reactive protein (hs-CRP) levels from baseline to four weeks..

Primary Outcome Measures

Name	Time	Method
Safety will be assessed by monitoring the incidence of adverse events	Baseline to four weeks.	Safety will be assessed by monitoring the incidence of adverse events from baseline to four weeks. Adverse events and tolerability will be evaluated using investigator-administered questionnaires at scheduled study visits. Participants will be asked to self-report any symptoms between visits, and all adverse events will be documented.
Efficacy will be determined by measuring the change in high-sensitivity C-reactive protein	Baseline to four weeks	Efficacy will be determined by measuring the change in high-sensitivity C-reactive protein (hs-CRP) levels from baseline to four weeks. The measurement of hs-CRP pre and post treatment will assess the change in hs-CRP with colchicine. This will test the hypothesis that LODOCO through the inhibition of the inflammatory pathways will lead to a decrease in hs-CRP levels.

Secondary Outcome Measures

Name	Time	Method
To investigate the changes in interleukin-6 (IL-6) levels with low-dose colchicine therapy in patients with statin intolerance.	baseline to four weeks	To assess the impact of low dose colchicine on IL-6, we will measure serum IL-6 levels in patients with statin intolerance at baseline and after 30 days of low-dose colchicine therapy. We hypothesize that there will be a significant reduction in IL-6 levels, reflecting a decrease in systemic inflammation.
To assess changes in lipid profile from baseline to 30 days	baseline to four weeks.	To evaluate lipid profile changes in statin-intolerant patients receiving low-dose colchicine by measuring total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), triglycerides, low-density lipoprotein cholesterol (LDL-C), and lipoprotein(a) \[Lp(a)\] at baseline and after 30 days of therapy. A 30-day time frame allows for observation of early changes in lipid parameters, which may help guide longer-term studies and inform clinical decision-making.
