BACKGROUND: CSL112 is a new formulation of human apolipoprotein A-I (apoA-I)
being developed to reduce cardiovascular events following acute coronary
syndrome. This phase 2a, randomized, double-blind, multicenter, dose-ranging
trial represents the first clinical investigation to assess the safety and
pharmacokinetics/pharmacodynamics of a CSL112 infusion among patients with stable
atherosclerotic disease. METHODS AND RESULTS: Patients were randomized to single
ascending doses of CSL112 (1.7, 3.4, or 6.8 g) or placebo, administered over a
2-hour period. Primary safety assessments consisted of alanine aminotransferase
or aspartate aminotransferase elevations >3× upper limits of normal and study
drug-related adverse events. Pharmacokinetic/pharmacodynamic assessments included
apoA-I plasma concentration and measures of the ability of serum to promote
cholesterol efflux from cells ex vivo. Of 45 patients randomized, 7, 12, and 14
received 1.7-, 3.4-, and 6.8-g CSL112, respectively, and 11 received placebo.
There were no clinically significant elevations (>3× upper limit of normal) in
alanine aminotransferase or aspartate aminotransferase. Adverse events were
nonserious and mild and occurred in 5 (71%), 5 (41%), and 6 (43%) patients in the
CSL112 1.7-, 3.4-, and 6.8-g groups, respectively, compared with 3 (27%) placebo
patients. The imbalance in adverse events was attributable to vessel
puncture/infusion-site bruising. CSL112 resulted in rapid (T(max)?2 hours) and
dose-dependent increases in apoA-I (145% increase in the 6.8-g group) and total
cholesterol efflux (up to 3.1-fold higher than placebo) (P<0.001). CONCLUSIONS:
CSL112 infusion was well tolerated in patients with stable atherosclerotic
disease. CSL112 immediately raised apoA-I levels and caused a rapid and marked
increase in the capacity of serum to efflux cholesterol. This potential novel
approach for the treatment of atherosclerosis warrants further investigation.
