Familial Hypercholesterolemia Clinical Trial
Official title:
Effects of an Adapted Brazilian Cardioprotective Diet Supplemented or Not With Phytosterols and/or Krill Oil in Patients With Familial Hypercholesterolemia: the DICA-FH Randomized Clinical Trial
The main objective of this randomized clinical trial is to evaluate the effects of the adapted Brazilian Cardioprotective Diet (DICA Br) supplemented or not with phytosterols and/or krill oil in patients with a probable or definitive diagnosis of familial hypercholesterolemia (FH) according to the the Dutch Lipid Clinic Network (Dutch MEDPED) criteria. In addition, the following will be considered secondary objectives: to perform participants´ whole genome sequencing (WGS); to evaluate the effects of the interventions on lipid profile biomarkers; to evaluate the frequency of mild, moderate and severe adverse events according to study groups; to identify the prevalence of subclinical atherosclerosis; to perform pharmacogenomic analysis; and to evaluate adherence rates according to study groups. In this study, 300 individuals will be randomly enrolled into four groups: 1) DICA Br adapted to the FH context (DICA-FH) + phytosterol placebo + krill oil placebo (control group); 2) DICA-FH + 2g/day of phytosterol + krill oil placebo; 3) DICA-FH + phytosterol placebo + 2g/day of krill oil; and 4) DICA-FH + 2g/day of phytosterol + 2g/day of krill oil. Primary outcomes will be LDL-cholesterol for groups phytosterol vs. placebo and lipoprotein(a) for groups krill oil vs. placebo after 120 days of follow up.
DICA-FH study is a superiority, factorial, and in parallel randomized placebo-controlled (double-dummy) clinical trial. The randomization will be in blocks stratified by research center, and the allocation ratio will be 1:1:1:1. Participants will come from at least 20 center sites in different Brazilian geographic regions. ;
