Phase 2: testing Colchicine for Heart Failure With Preserved Ejection Fraction

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

Official registry: https://clinicaltrials.gov/study/NCT06217120 · Montreal Heart Institute · enrollment listed as 64

What this phase means

Phase 2: researchers already know a roughly safe dose (from phase 1). This stage asks whether the treatment actually helps the condition, and watches side effects more closely.

Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.

What the registry says happens

If you join, the listed intervention(s) are Colchicine, or Placebo. The registry lists allocation as randomized. This study will measure the impact of colchicine on the change in myocardial flow reserve (MFR), a marker for coronary microvascular dysfunction (CMD), compared to a matched dummy treatment (placebo) in patients with heart failure and ejection fraction above 40% (including patients with improved EF).

They plan to enroll about 64 people at Montreal. Taking part typically means taking a study drug (or dummy pill) plus check-ins.

Not a traditional drug phase: measurement of RNAs for Heart Failure

This study is aimed to investigate the global transcriptome in order to determine the expression profile of messenger RNAs (mRNAs), as well as long noncoding- (lncRNAs) and micro noncoding-RNAs (miRNAs) in heart failure (HF) and in aortic stenosis (AS). The aim is to clarify their role in cardiac disease pathogenesis, as well as their potential as biomarkers.

Not a traditional drug phase: testing The POP02 study is collecting bodily fluid samples (i.e., whole blood, effluent samples) of children prescribed the following drugs of interest per standard of care: for Coronavirus Infection (COVID-19)

The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to measure the PK of understudied drugs currently being administered to children per SOC as prescribed by their treating provider.
