A single infusion of MDCO-216 (ApoA-1 Milano/POPC) increases ABCA1-mediated cholesterol efflux and pre-beta 1 HDL in healthy volunteers and patients with stable coronary artery disease.

Aims: Apolipoprotein A-1 (ApoA-1), based on epidemiology, is inversely associated with cardiovascular (CV) events. Human carriers of the ApoA-1 Milano variant have a reduced incidence of CV disease. Regression of atherosclerotic plaque burden was previously observed on intravascular ultrasound (IVUS) with ETC-216, a predecessor of MDCO-216.

Electrocardiographic Effects of a Supratherapeutic Dose of Oritavancin.

The purpose of this study was to measure oritavancin's electrocardiographic effects at a supratherapeutic dose of 1600 mg given intravenously (IV) over 3 hours. A cohort of 150 healthy volunteers were randomized to receive placebo, oritavancin, or oral moxifloxacin 400 mg in a parallel designed thorough QT study. A supratherapeutic mean maximum oritavancin concentration (C ) of 232 μg/mL was achieved.

High-Density Lipoprotein Subfractions and Cholesterol Efflux Capacities After Infusion of MDCO-216 (Apolipoprotein A-IMilano/Palmitoyl-Oleoyl-Phosphatidylcholine) in Healthy Volunteers and Stable Coronary Artery Disease Patients.

Objective: To determine effects of single ascending doses of MDCO-216 on high-density lipoprotein (HDL) subfractions in relation to changes in cholesterol efflux capacity in healthy volunteers and in patients with stable angina pectoris.

Approach And Results: Doses of 5- (in volunteers only), 10-, 20-, 30-, and 40-mg/kg MDCO-216 were infused during 2 hours, and plasma and serum were collected during 30 days. Plasma levels of HDL subfractions were assessed by 2-dimensional gel electrophoresis, immunoblotting, and image analysis.

Population pharmacokinetic analysis for a single 1,200-milligram dose of oritavancin using data from two pivotal phase 3 clinical trials.

Oritavancin is a lipoglycopeptide antibiotic with activity against Gram-positive bacteria. Here we describe oritavancin population pharmacokinetics and the impact of patient-specific covariates on drug exposure variability. Concentration-time data were analyzed from two phase 3 clinical trials, SOLO I and SOLO II, in which oritavancin was administered as a single 1,200-mg dose to patients with acute bacterial skin and skin structure infections.

Electrocardiographic safety of cangrelor, a new intravenous antiplatelet agent: a randomized, double-blind, placebo- and moxifloxacin-controlled thorough QT study.

Cangrelor is an intravenous P2Y12 inhibitor under investigation as an antiplatelet drug in the setting of acute coronary syndromes. To determine the electrophysiologic safety of parenteral cangrelor, cardiac repolarization effects were measured in 67 healthy volunteers (aged 18-45 years) in a randomized crossover design, including 4 treatment sequences of therapeutic cangrelor, supratherapeutic cangrelor, placebo, and moxifloxacin (positive control). Triplicate electrocardiogram measurements and pharmacokinetic samples were collected at baseline and 9 time points postdose on day 1.
