Evolocumab for PCSK9 Lowering in Early Acute Sepsis (The PLEASe Study) (PLEASe)
March 2, 2020 updated by: john boyd, University of British Columbia
Randomized, Double-blind, Placebo-controlled Phase 2a Trial of Efficacy and Safety of Evolocumab for PCSK9 Lowering in Early Acute Sepsis
This study evaluates using evolocumab, a currently approved and marketed biologic drug, in a novel way.
Patients who present to the emergency room or intensive care unit (ICU) with severe infection are eligible.
Either the patient or their designated decision maker will be approached for consent.
If they choose to participate they will be given either a single dose of evolocumab, a higher single dose of evolocumab,or a single dose of placebo.
Participants will be followed during their stay in the ICU and will receive follow up phone calls at Day 28 and 90.
Study Overview
Detailed Description
Evolocumab is currently approved and marketed in USA and Canada for lowering cholesterol levels.
Evolocumab is an anti-PSCK9 monoclonal antibody, and functions by binding PSCK9 (an inhibitor of LDL removal) and blocking its function.
Evidence suggests that since evolocumab increases the removal rate of low-density lipoproteins from the body, it might also help increase the removal of bacterial components that are attached to circulating lipids during sepsis.
Quickly removing these bacterial components could prevent a strong and rapid immune response that often leads to organ failure and death in sepsis patients.
