Efficacy and Safety of Evinacumab in Adult Patients With Severe Hypertriglyceridemia for the Prevention of Recurrent Acute Pancreatitis

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT04863014
Recruitment Status : Terminated (Sponsor Decision)
First Posted : April 28, 2021
Last Update Posted : March 22, 2023
Information provided by (Responsible Party):
Regeneron Pharmaceuticals

Brief Summary:

The primary objective of the study is to determine the proportion of patients with elevated triglycerides (TG), without familial chylomicronemia syndrome (FCS) due to loss of function (LoF) mutations in lipoprotein lipase (LPL), and a history of hypertriglyceridemia (HTG)-associated acute pancreatitis (AP) who experience a recurrent episode of AP after treatment with evinacumab versus placebo.

The secondary objectives of the study are:

  • To determine the change in the standard lipid profile after therapy with evinacumab versus placebo
  • To determine the changes in specialty lipoprotein parameters (ApoC3, ApoB48, ApoB100, and nuclear magnetic resonance [NMR] lipid profile) after therapy with evinacumab versus placebo
  • To measure the number of AP episodes per patient
  • To assess the safety and tolerability of evinacumab
  • To assess the potential immunogenicity of evinacumab
  • To assess the concentrations of total evinacumab and total angiopoietin-like 3 (ANGPTL3)
