BACKGROUND: Many patients with heterozygous familial hypercholesterolemia (HeFH) fail to reach optimal low-density lipoprotein cholesterol (LDL-C) levels with available lipid-lowering medications, including statins, and require treatment using alternative methods such as lipoprotein apheresis.
OBJECTIVE: To evaluate the efficacy of alirocumab 150 mg every 2 weeks (Q2W) compared with placebo in reducing the frequency of lipoprotein apheresis treatments in patients with HeFH.
METHODS: ODYSSEY ESCAPE is a randomized, double-blind, placebo-controlled, parallel-group, 18-week, phase 3 study being conducted in the United States and Germany. ODYSSEY ESCAPE will evaluate the efficacy and safety of alirocumab in approximately 63 adults with HeFH undergoing regular weekly (QW; for ≥4 weeks) or Q2W (for ≥8 weeks) lipoprotein apheresis. Patients will be randomly assigned (2:1, respectively) to receive alirocumab 150 mg subcutaneously Q2W or placebo subcutaneously Q2W (both in 1-mL injections) for 18 weeks. From day 1 to week 6, the apheresis frequency will be fixed to the individual patient's established schedule (QW or Q2W); thereafter, apheresis will be performed according to the LDL-C value at that visit: apheresis will not be performed when the LDL-C value is ≥30% lower than the baseline pre-apheresis LDL-C value. The primary end point is the frequency of apheresis treatments over a 12-week period starting at week 7.
DISCUSSION: The ODYSSEY ESCAPE trial will determine whether alirocumab reduces the frequency of lipoprotein apheresis in patients with HeFH.
