Condition(s) targeted: Hypertriglyceridemia; Gout; Pericarditis

Intervention: Colchicine (Drug)

Phase: Phase 0

Status: Completed

Sponsored by: Scripps Translational Science Institute

Official(s) and/or principal investigator(s):
Peter Schultz, PhD, Principal Investigator, Affiliation: Scripps Translational Science Institute

Summary

The aim of this trial will be to determine an effect-size for the administration of chronic low-dose colchicine in the reduction of serum levels of triglycerides (TG), very-low density lipoproteins (VLDL), and apolipoprotein CIII (apoCIII) in human subjects over a period of 4-6 weeks.

Clinical Details

Official title: A Translational Study to Understand the Mechanism of Apolipoprotein CIII Reduction Via Colchicine

Study design: Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Basic Science

Primary outcome:

Reduction in ApoCIII levels

Reduction of triglycerides and very low density lipoprotein (VLDL) levels

Secondary outcome: Measurement of Apolipoprotein A and Apolipoprotein B via Vertical Auto Profile (VAP)

Detailed description: The aim of this proposal will be to show, in a translational fashion, a relationship between colchicine and reduction of factors affecting triglyceride metabolism, especially apoCIII and VLDL levels. We envision colchicine as playing a role in identifying and elucidating a new mechanism for lowering TG levels, which may have a great impact on targeting patients who have not met non-HDL goals according to Adult Treatment Panel III (ATPIII guidelines) or at risk for hypertriglyceridemia-induced pancreatitis [11]. We will accomplish this by conducting a prospective cohort clinical trial of low-dose colchicine in hypertriglyceridemic patients to assess percent (%) reduction of apoCIII, VLDL, and TG. Secondary endpoints will be to observe the effects of colchicine on apoA, apoB, HDL, low-density lipoprotein (LDL), and total cholesterol (TC).
