Effects of PCSK9 Inhibition by Evolocumab on Postprandial Lipid Metabolism in Type 2 Diabetes
October 28, 2021 updated by: Marja-Riitta Taskinen
Postprandial lipemia is highly prevalent in type 2 diabetes subjects even with normal fasting triglyceride values.
Humans are mostly in a postprandial rather than in a fasting state and therefore non-fasting triglyceride values reflect more accurately the continuous exposure of arterial wall to the substantial cholesterol load from remnant particles.
Evolocumab lowers blood LDL-cholesterol.
This study evaluates the effect of evolocumab on postprandial lipid metabolism in type 2 diabetes.
All participants in this study receive evolocumab treatment.

Description
Inclusion Criteria:
- Male or female (non-fertile or using a medically approved birth control method) overweight/obese subjects with Type 2 Diabetes Mellitus treated with lifestyle counselling and a stable metformin dose for at least three months
- age 18-77 yrs.

- glycohemoglobin: ≤9%.
- Each patient will attend a pre-screening visit (at week -5) where eligibility criteria will be evaluated. If the patient uses another statin than atorvastatin (20 mg) at screening visit the used statin is stopped and atorvastatin 20 mg will be initiated. If the patient is not using any statin, atorvastatin 20 mg will be initiated and the lipid values will be checked after 4 weeks when all inclusion/exclusion criteria will be assessed.

Mean Total Production of ApoB48 Before and After Evolocumab
Time Frame: Baseline and after 12 weeks
|
Change in ApoB48 total production in plasma measured by using multicompartmental modeling.
The power of mathematical modelling to describe the metabolic pathways of lipid and lipoprotein metabolism was demonstrated by Zech L et al (J Clin Invest 1979;63:1262-1273) and have been widely used over 30yrs.
So far few studies have focused on the modelling of apo B48 and apo B100 after a meal that is more physiological than the fasting state (Björnson E et al.
JIM 2019;285:562-577).
Production rates for apo B48, apo B100 and triglycerides in chylomicrons, VLDL1 and VLDL2 were derived from samples taken before and after the tracer injection and after the meal at 0, 30, 45, 60, 75, 90, 120, 150 min and at 3, 4, 5, 6, 8, 10, 24 hrs and averages for 24 hrs.
Analysis of tracer/ tracee curves of stable isotopes was used to derived the estimates of kinetic parameters using a new mathematical modeling per day.
These figures per day are used to report the data from this study.
