Anti-inflammatory

Colchicine for Aortic Stenosis (COPAS-Pilot Trial)

Phase 2 & 3
Recruiting
Led By David Messika-Zetioun@ottawaheart.ca
Research Sponsored by Ottawa Heart Institute Research Corporation
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Mild to moderate aortic stenosis defined by a mean pressure gradient using transthoracic echocardiography (TTE) between 15-25mmHg
Age greater than 18 years
Must not have
Use of p-glycoprotein inhibitor (e.g. cyclosporine, verapamil, or quinidine) or a strong CYP3A4 inhibitor (e.g. ritonavir, clarithromycin, or ketoconazole)
Associated other valvular pathology of moderate or greater severity
Timeline
Screening 3 weeks
Treatment Varies
Follow Up one year

Summary

This trial tests if colchicine, an anti-inflammatory drug, can reduce calcium buildup in the heart valves of patients with mild to moderate aortic stenosis. The study will test colchicine over several months to see if it helps reduce valve hardening. Colchicine has shown modest benefits in early nonsevere COVID-19 but is associated with common adverse effects.

Who is the study for?
Adults over 18 with mild to moderate aortic stenosis (15-25mmHg pressure gradient) can join this study. They must be able to consent and agree to use two forms of contraception if capable of childbearing. Excluded are those with severe heart issues, liver disease, immune compromise, certain medication use, recent cancer (except some skin cancers), pregnancy, breastfeeding or poor kidney function.
What is being tested?
The COPAS pilot is testing whether Colchicine can slow down the hardening of the aortic valve by comparing it against a placebo. Participants will be randomly assigned to one of these two groups in a double-blind manner and monitored for 6 months using NaF PET imaging.
What are the potential side effects?
Colchicine may cause side effects like digestive upset (nausea, diarrhea), blood disorders, muscle pain or weakness. Since this is a blinded trial, participants won't know if they're getting Colchicine or the placebo until after the study.

Research Highlights

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Colchicine, a common anti-inflammatory treatment, works by inhibiting microtubule polymerization, which reduces neutrophil activity and migration to inflammation sites. This mechanism helps decrease the overall inflammatory response, making it an effective option for reducing inflammation and its symptoms, thereby potentially improving patient outcomes and quality of life.
