Abstract

The phase 3 ODYSSEY OPTIONS studies (OPTIONS I, NCT01730040; OPTIONS II, NCT01730053) are multicenter, multinational, randomized, double-blind, active-comparator, 24-week studies evaluating the efficacy and safety of alirocumab, a fully human monoclonal antibody targeting proprotein convertase subtilisin/kexin type 9, as add-on therapy in ∼ 650 high-cardiovascular (CV)-risk patients whose low-density lipoprotein cholesterol (LDL-C) levels are ≥100 mg/dL or ≥70 mg/dL according to the CV-risk category, high and very high CV risk, respectively, with atorvastatin (20-40 mg/d) or rosuvastatin (10-20 mg/d). Patients are randomized to receive alirocumab 75 mg via a single, subcutaneous, 1-mL injection by prefilled pen every 2 weeks (Q2W) as add-on therapy to atorvastatin (20-40 mg) or rosuvastatin (10-20 mg); or to receive ezetimibe 10 mg/d as add-on therapy to statin; or to receive statin up-titration; or to switch from atorvastatin to rosuvastatin (OPTIONS I only). At week 12, based on week 8 LDL-C levels, the alirocumab dose may be increased from 75 mg to 150 mg Q2W if LDL-C levels remain ≥100 mg/dL or ≥70 mg/dL in patients with high or very high CV risk, respectively. The primary efficacy endpoint in both studies is difference in percent change in calculated LDL-C from baseline to week 24 in the alirocumab vs control arms. The studies may provide guidance to inform clinical decision-making when patients with CV risk require additional lipid-lowering therapy to further reduce LDL-C levels. The flexibility of the alirocumab dosing regimen allows for individualized therapy based on the degree of LDL-C reduction required to achieve the desired LDL-C level.
