Project Title:48 hours Post-treatment L-Carnitine Pharmacometabolomics in Sepsis (CaPS) Study
Project Type:Quantitative NMR Metabolomics
Project Summary:To utilize existing serum samples from the phase II clinical trial of L-carnitine treatment for severe sepsis to metabolically phenotype L-carnitine responders and non-responders. Methods: Serum samples collected prior to (T0) and after completion of the infusion (T24, T48) from patients randomized to either low (6 g), intermediate (12g), high (18g) L-carnitine or placebo for the treatment of vasopressor dependent septic shock were assayed by untargeted 1H-nuclear magnetic resonance metabolomics.

Treatment:

Treatment ID:TR001443
Treatment Summary:Pharmacists and staff prepared either levocarnitine or placebo in identical polypropylene infusion bags with labels that included the study identification number, patient name, medical record number, and infusion rate. For each dose of levocarnitine, 33% of the total dose was administered as a 20-mL bolus over 2 to 3 minutes, followed by a fixed-rate continuous infusion of 1 L over the next 12 hours. The study solution was administered through intravenous (IV) catheters using US Food and Drug JAMA Network Open | Critical Care Medicine Effect of Levocarnitine vs Placebo as an Adjunctive Treatment for Septic Shock JAMA Network Open. 2018;1(8):e186076. doi:10.1001/jamanetworkopen.2018.6076 (Reprinted) December 21, 2018 3/12 Downloaded From: https://jamanetwork.com/ by a University of Michigan User on 02/07/2020 Administration–approved medical equipment (IV tubing, IV pumps, etc).
