Physiologically based pharmacokinetic modeling of CYP2C8 substrate rosiglitazone and its metabolite to predict metabolic drug-drug interaction. Drug Metab Pharmacokinet 2024; 57:101023. [PMID: 39088906 DOI: 10.1016/j.dmpk.2024.101023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 04/15/2024] [Accepted: 05/26/2024] [Indexed: 08/03/2024]
Abstract
Rosiglitazone is an activator of nuclear peroxisome proliferator-activated (PPAR) receptor gamma used in the treatment of type 2 diabetes mellitus. The elimination of rosiglitazone occurs mainly via metabolism, with major contribution by enzyme cytochrome P450 (CYP) 2C8. Primary routes of rosiglitazone metabolism are N-demethylation and hydroxylation. Modulation of CYP2C8 activity by co-administered drugs lead to prominent changes in the exposure of rosiglitazone and its metabolites. Here, we attempt to develop mechanistic parent-metabolite physiologically based pharmacokinetic (PBPK) model for rosiglitazone. Our goal is to predict potential drug-drug interaction (DDI) and consequent changes in metabolite N-desmethyl rosiglitazone exposure. The PBPK modeling was performed in the PKSim® software using clinical pharmacokinetics data from literature. The contribution to N-desmethyl rosiglitazone formation by CYP2C8 was delineated using vitro metabolite formation rates from recombinant enzyme system. Developed model was verified for prediction of rosiglitazone DDI potential and its metabolite exposure based on observed clinical DDI studies. Developed model exhibited good predictive performance both for rosiglitazone and N-desmethyl rosiglitazone respectively, evaluated based on commonly acceptable criteria. In conclusion, developed model helps with prediction of CYP2C8 DDI using rosiglitazone as a substrate, as well as changes in metabolite exposure. In vitro data for metabolite formation can be successfully utilized to translate to in vivo conditions.

Abstract
Cardiovascular outcome trials on omega-3 fatty acids have generated contradictory results but indicate a dose-dependent beneficial effect of eicosapentaenoic acid (EPA). Beneficial cardiovascular effects of EPA may in addition to triglyceride lowering be mediated through alternative mechanisms of action. In this review, the link between EPA and a resolution of atherosclerotic inflammation is addressed. EPA is a substrate for the enzymatic metabolism into the lipid mediator resolvin E1 (RvE1), which activates the receptor ChemR23 to transduce an active resolution of inflammation. This has been shown to dampen the immune response and provide atheroprotective responses in different models. The intermediate EPA metabolite 18-HEPE emerges as a biomarker of EPA metabolism towards proresolving mediators in observational studies. Genetic variations within the EPA-RvE1-ChemR23 axis affecting the response to EPA may open up for precision medicine to identify responders and non-responders to EPA and fish oil supplementation. In conclusion, activation of the EPA-RvE1-ChemR23 axis towards a resolution of inflammation may contribute to beneficial effects in cardiovascular prevention.

Pharmacokinetics of Single and Multiple Oral Administration of a Self-emulsifying Formulation of Highly Purified Eicosapentaenoic Acid Ethyl Ester (MND-2119) Compared With the Nonself-emulsifying Formulation in Healthy Male Subjects. Clin Pharmacol Drug Dev 2023; 12:107-115.

Abstract
MND-2119 is a self-emulsifying formulation of highly purified eicosapentaenoic acid ethyl ester (EPA-E) designed to be administered once daily due to improved absorption compared with the nonself-emulsifying formulation. In these studies, MND-2119 was administered to healthy adult males in single or multiple doses. In the single administration study, MND-2119 (0.5-4 g) was administered under fed and fasted conditions to evaluate MND-2119 pharmacokinetics and safety under these conditions. This study showed that Cmax and AUC0-72h of plasma EPA concentration after single administration were higher under fed conditions than under fasted conditions, for all doses. In the multiple administration study, subjects received either MND-2119 (0.5-4 g) immediately after breakfast or EPA-E (0.9 g) immediately after breakfast and dinner for 11 days to compare pharmacokinetics and safety of MND-2119 to EPA-E. In this study, the rate of rise in Cmin of the plasma EPA concentration with MND-2119 decreased from days 6 to 8 after administration and was thought to have reached a steady state on day 11. The mean Css,max of MND-2119 administered as 1 g once daily, and the mean Css,min and the mean AUCss,0-24h of MND-2119 administered as 2 g once daily were higher than those of EPA-E administered as 0.9 g twice daily. No safety-related issues occurred in either study. These results suggest that MND-2119 administered once daily may achieve equivalent or higher plasma EPA concentrations compared to the nonself-emulsifying formulation administered twice daily.

Abstract
Introduction: Reduction of low-density-lipoprotein cholesterol (LDL-C) and other apolipoprotein B (apoB)-containing lipoproteins reduces cardiovascular (CV) events and greater reductions have greater benefits. Current lipid treatments cannot always achieve desirable LDL-C targets and additional or alternative treatments are often needed.Areas covered: In this article, we review the pharmacokinetics of the available and emerging treatments for hypercholesterolemia and focus on recently approved drugs and those at a late stage of development.Expert opinion: Statin pharmacokinetics are well known and appropriate drugs and doses can usually be chosen for individual patients to achieve LDL-C targets and avoid adverse effects and drug-drug interactions. Ezetimibe, icosapent ethyl and the monoclonal antibodies evolocumab and alirocumab have established efficacy and safety. Newer oral agents including pemafibrate and bempedoic acid have generally favorable pharmacokinetics supporting use in a wide range of patients. RNA-based therapies with antisense oligonucleotides are highly specific for their targets and those inhibiting apoB, apoCIII, angiopoietin-like protein 3 and lipoprotein(a) have shown promising results. The small-interfering RNA inclisiran has the notable advantage that a single subcutaneous administration may be effective for up to 6 months. The CV outcome trial results and long term safety data are eagerly awaited for these new agents.

Abstract
The omega-3 fatty acid eicosapentaenoic acid (EPA) has multiple actions potentially conferring cardiovascular benefit, including lowering serum triglyceride (TG) and non-high-density lipoprotein cholesterol (non-HDL-C) levels and potentially reducing key steps in atherogenesis. Dietary supplements are a common source of omega-3 fatty acids in the US, but virtually all contain docosahexaenoic acid (DHA) in addition to EPA, and lipid effects differ between DHA and EPA. Contrary to popular belief, no over-the-counter omega-3 products are available in the US, only prescription products and dietary supplements. Among the US prescription omega-3 products, only one contains EPA exclusively (Vascepa); another closely related prescription omega-3 product also contains highly purified EPA, but is approved only in Japan and is provided in different capsule sizes. These high-purity EPA products do not raise low-density lipoprotein cholesterol (LDL-C) levels, even in patients with TG levels >500 mg/dL, in contrast to the increase in LDL-C levels with prescription omega-3 products that also contain DHA. The Japanese prescription EPA product was shown to significantly reduce major coronary events in hypercholesterolemic patients when added to statin therapy in the Japan EPA Lipid Intervention Study (JELIS). The effects of Vascepa on cardiovascular outcomes are being investigated in statin-treated patients with high TG levels in the Reduction of Cardiovascular Events With EPA-Intervention Trial (REDUCE-IT).

Abstract
Type 2 diabetes mellitus (T2DM) and metabolic syndrome contribute to hypertriglyceridemia, which may increase residual risk of cardiovascular disease in patients with elevated triglyceride (TG) levels despite optimal low-density lipoprotein cholesterol (LDL-C) levels with statin therapy. Prescription products containing the long-chain omega-3 fatty acids (OM3FAs) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are an effective strategy for reducing TG levels. This article provides an overview of prescription OM3FAs, including relevant clinical data in patients with T2DM and/or metabolic syndrome. Prescription OM3FAs contain either combinations of DHA and EPA (omega-3-acid ethyl esters, omega-3-carboxylic acids, omega-3-acid ethyl esters A) or EPA alone (icosapent ethyl). These products are well tolerated and can be used safely with statins. Randomized controlled trials have demonstrated that all prescription OM3FAs produce statistically significant reductions in TG levels compared with placebo; however, differential effects on LDL-C levels have been reported. Products containing DHA may increase LDL-C levels, whereas the EPA-only product did not increase LDL-C levels compared with placebo. Because increases in LDL-C levels may be unwanted in patients with T2DM and/or dyslipidemia, the EPA-only product should not be replaced with products containing DHA. Available data on the effects of OM3FAs in patients with diabetes and/or metabolic syndrome support that these products can be used safely in patients with T2DM and have beneficial effects on atherogenic parameters; in particular, the EPA-only prescription product significantly reduced TG, non-high-density lipoprotein cholesterol, Apo B, remnant lipoprotein cholesterol, and high-sensitivity CRP levels without increasing LDL-C levels compared with placebo. Ongoing studies of the effects of prescription OM3FAs on cardiovascular outcomes will help determine whether these products will emerge as effective add-on options to statin therapy for reduction of residual cardiovascular disease risk.

Abstract
An estimated 25% of adults in the United States have elevated triglyceride (TG) levels. This is of particular concern given the evidence for a causal role of TG in the pathway of cardiovascular (CV) disease. Approved prescription omega-3 fatty acid products (RxOM3FAs) contain the long-chain fatty acids docosahexaenoic acid (DHA) and/or eicosapentaenoic acid (EPA) and are effective options for the treatment of high TG levels. RxOM3FAs that contain both EPA and DHA include omega-3-acid ethyl esters (ethyl esters of EPA and DHA; brand and generic products) and omega-3-carboxylic acids (free fatty acids primarily composed of EPA and DHA), while the RxOM3FA icosapent ethyl (the ethyl ester of EPA) contains EPA only. All RxOM3FA products produce substantial TG reduction and other beneficial effects on atherogenic lipid and inflammation-related parameters, blood pressure, and heart rate variability, but products that contain DHA may raise low-density lipoprotein-cholesterol (LDL-C). This commentary provides an overview of hypertriglyceridemia while summarizing the pharmacology, efficacy, and safety of prescription RxOM3FAs.
