Obicetrapib
Phase 2 trial in 120 patients: obicetrapib on top of high-intensity statins cuts LDL-C by up to 51% and raises HDL-C by up to 165% (Nat Med 2022)
Original title: Lipid lowering effects of the CETP inhibitor obicetrapib in combination with high-intensity statins: a randomized phase 2 trial
A randomised, double-blind, placebo-controlled phase 2 trial (NCT04753606) tested obicetrapib 5 mg or 10 mg against placebo, added to background high-intensity statin therapy, in 120 dyslipidaemic patients with median baseline LDL-C of 88 mg/dL. Over 8 weeks, obicetrapib produced a significant placebo-adjusted decrease in median LDL-C of up to 51% (P < 0.0001), the primary outcome, alongside significant decreases in apoB of up to 30% and non-HDL-C of up to 44%, and a significant increase in HDL-C of up to 165% (all P < 0.0001, secondary outcomes). The safety profile was acceptable. An early phase 2 dataset supporting the later phase 3 development of obicetrapib, ahead of dedicated cardiovascular outcomes data.
Original abstract
Global guidelines for the management of high-cardiovascular-risk patients include aggressive goals for low-density lipoprotein cholesterol (LDL-C). Statin therapy alone is often insufficient to reach goals and nonstatin options have limitations. Here, we tested the lipid-lowering effects of the cholesteryl ester transfer protein (CETP) inhibitor drug obicetrapib in a randomized, double-blind, placebo-controlled trial in dyslipidaemic patients (n = 120, median LDL-C 88 mg dl-1) with background high-intensity statin treatment (NCT04753606). Over the course of 8 weeks, treatment with 5 mg or 10 mg obicetrapib resulted in a significant decrease as compared with placebo in median LDL-C concentration (by up to 51%; P < 0.0001), the primary trial outcome. As compared with placebo, obicetrapib treatment also significantly (P < 0.0001) decreased apolipoprotein B (by up to 30%) and non-high-density lipoprotein cholesterol (non-HDL-C) concentration (by up to 44%), and significantly (P < 0.0001) increased HDL-C concentration (by up to 165%; the secondary trial outcomes) and had an acceptable safety profile. These results support the potential of obicetrapib to address an unmet medical need for high-cardiovascular-risk patients.
