| Popis: | This report describes the lipid and safety data collected during an off-drug period that followed 8 weeks of treatment with the cholesteryl ester transfer protein inhibitor, anacetrapib (ANA). A total of 589 patients with primary hypercholesterolemia or mixed hyperlipidemia were randomized to placebo, atorvastatin (ATV) 20 mg, and varying doses of ANA, provided as monotherapy or coadministered with ATV 20 mg daily. Patients were treated for 8 weeks, followed by an 8-week follow-up period, during which ANA was switched to placebo. At week 16 (8 weeks after ANA was stopped), persistent reductions in low-density lipoprotein cholesterol (LDL-C) were evident for the monotherapy groups receiving ANA 150 and 300 mg (-9.3% and -15.3%, respectively), and residual increases in high-density lipoprotein cholesterol (HDL-C) were observed for the monotherapy groups receiving ANA 40 mg (18.6%), 150 mg (40.5%), and 300 mg (43.4%). The effects on apolipoprotein B and apolipoprotein A-I were consistent with the changes observed for LDL-C and HDL-C, respectively. Corresponding residual changes in LDL-C and HDL-C were also noted in the ATV coadministration groups at the similar doses of ANA compared with ATV 20 mg alone. Residual plasma drug levels accompanied by reductions in cholesteryl ester transfer protein activity were observed at week 16 and may account for the alterations in plasma lipids 8 weeks after cessation of ANA. |
