ReviewGene-based therapies in lipidology: current status and future challenges.
Gene-based therapies are designed to modulate gene expression in specific tissues by introducing into cells transgenes, antisense oligonucleotides, RNA interference, microRNAs, or a variety of other oligonucleotide-based compounds and their delivery systems. Several types of gene-based therapies are already available or in clinical development to treat severe lipid-related disorders and associated risk. The review briefly presents the current status and future challenges of these therapies in clinical lipidology, focusing on most advanced and promising agents or mechanisms. ⋯ Although positive to date, the overall benefit-risk ratio of gene-based therapies is yet to be documented long term across additional patients and conditions. The next generation of such therapies might improve their therapeutic index.

We provide an overview of recent advances in the therapy of hypertriglyceridemia, focusing on several new therapies with potential for treating of familial chylomicronemia, other forms of hypertriglyceridemia, and for triglyceride-lowering in patients with other lipid disorders. ⋯ Several promising triglyceride-lowering therapies are at various stages of development; a few are even available in some markets. Although existing data suggest good biochemical efficacy, data on long-term clinical outcomes are still limited. For some therapies, cost will be an important consideration, and use will likely be restricted to orphan indications, for example very severe cases of hypertriglyceridemia as seen in familial chylomicronemia syndrome, although some therapies could theoretically be more broadly used one day for cardiovascular disease prevention.

Randomized Controlled Trial
Antisense therapy targeting apolipoprotein(a): a randomised, double-blind, placebo-controlled phase 1 study.
Lipoprotein(a) (Lp[a]) is a risk factor for cardiovascular disease and calcific aortic valve stenosis. No effective therapies to lower plasma Lp(a) concentrations exist. We have assessed the safety, pharmacokinetics, and pharmacodynamics of ISIS-APO(a)Rx, a second-generation antisense drug designed to reduce the synthesis of apolipoprotein(a) (apo[a]) in the liver. ⋯ Isis Pharmaceuticals.
