Participant gender:
All
Summary
COPAS pilot is a pilot single center double blinded randomized study to determine the effect of targeted anti-inflammation therapy using colchicine, on valvular calcification activity using imaging, i.e. aortic valvular NaF uptake. The current proposal uses a randomized design to evaluate the effect of colchicine vs. placebo on valvular calcification activity over 6 months measured using NaF PET
Phase:
Phase 2/Phase 3
Accepts Healthy Volunteers?
