PURPOSE OF REVIEW: To review recent lecithin:cholesterol acyltransferas (LCAT)-based therapeutic approaches for atherosclerosis, acute coronary syndrome, and LCAT deficiency disorders.
RECENT FINDINGS: A wide variety of approaches to using LCAT as a novel therapeutic target have been proposed. Enzyme replacement therapy with recombinant human LCAT is the most clinically advanced therapy for atherosclerosis and familial LCAT deficiency (FLD), with Phase I and Phase 2A clinical trials recently completed. Liver-directed LCAT gene therapy and engineered cell therapies are also another promising approach. Peptide and small molecule activators have shown efficacy in early-stage preclinical studies. Finally, lifestyle modifications, such as fat-restricted diets, cessation of cigarette smoking, and a diet rich in antioxidants may potentially suppress lipoprotein abnormalities in FLD patients and help preserve LCAT activity and renal function but have not been adequately tested.
SUMMARY: Preclinical and early-stage clinical trials demonstrate the promise of novel LCAT therapies as HDL-raising agents that may be used to treat not only FLD but potentially also atherosclerosis and other disorders with low or dysfunctional HDL.
