A single dose of the apolipoprotein (apo)A-I mimetic peptide D-4F rendered
high-density lipoprotein (HDL) less inflammatory, motivating the first
multiple-dose study. We aimed to assess safety/tolerability, pharmacokinetics,
and pharmacodynamics of daily, orally administered D-4F. High-risk coronary heart
disease (CHD) subjects added double-blinded placebo or D-4F to statin for 13
days, randomly assigned 1:3 to ascending cohorts of 100, 300, then 500 mg (n =
62; 46 men/16 women). D-4F was safe and well-tolerated. Mean ± SD plasma D-4F
area under the curve (AUC, 0-8h) was 6.9 ± 5.7 ng/mL*h (100 mg), 22.7 ± 19.6
ng/mL*h (300 mg), and 104.0 ± 60.9 ng/mL*h (500 mg) among men, higher among
women. Whereas placebo dropped HDL inflammatory index (HII) 28% 8 h postdose
(range, 1.25-0.86), 300-500 mg D-4F effectively halved HII: 1.35-0.57 and
1.22-0.63, respectively (P < 0.03 vs. placebo). Oral D-4F peptide dose predicted
HII suppression, whereas plasma D-4F exposure was dissociated, suggesting plasma
penetration is unnecessary. In conclusion, oral D-4F dosing rendered HDL less
inflammatory, affirming oral D-4F as a potential therapy to improve HDL function.
