Abstract
There is significant variability in the efficacy and safety of oral P2Y12 inhibitors, which are used to prevent ischemic outcomes in common diseases such as coronary and peripheral arterial disease and stroke. Clopidogrel, a prodrug, is the most used oral P2Y12 inhibitor and is activated primarily after being metabolized by a highly polymorphic hepatic cytochrome CYP2C219 enzyme. Loss-of-function genetic variants in CYP2C219 are common, can result in decreased active metabolite levels and increased on-treatment platelet aggregation, and are associated with increased ischemic events on clopidogrel therapy. Such patients can be identified by CYP2C19 genetic testing and can be treated with alternative therapy. Conversely, universal use of potent oral P2Y12 inhibitors such as ticagrelor or prasugrel, which are not dependent on CYP2C19 for activation, has been recommended but can result in increased bleeding. Recent clinical trials and meta-analyses have demonstrated that a precision medicine approach in which loss-of-function carriers are prescribed ticagrelor or prasugrel and noncarriers are prescribed clopidogrel results in reducing ischemic events without increasing bleeding risk. The evidence to date supports CYP2C19 genetic testing before oral P2Y12 inhibitors are prescribed in patients with acute coronary syndromes or percutaneous coronary intervention. Clinical implementation of such genetic testing will depend on among multiple factors: rapid availability of results or adoption of the concept of performing preemptive genetic testing, provision of easy-to-understand results with therapeutic recommendations, and seamless integration in the electronic health record.

Abstract
Medical economics is essential in cardiac genetics for the clinical application and development of research results. However, related economic evaluations are unclear, and limited systematic reviews are available on the cost-effectiveness of drug selection based on the CYP2C19 LOF allele. This review analyzed research in the MEDLINE database from January 2012 to June 2023 using more evidence than a well-designed cohort study, owing to the lack of relevant research in the database. For example, cost-effectiveness analyses are often reported as simulation assays, and were included in this analysis. No conditions related to patient background or antiplatelet drug therapy were selected. This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement (2020). Twenty-one cardiac genetic studies were selected, of which nineteen involved antiplatelet therapy after PCI. A universal group consisting of clopidogrel and other drugs was used as the baseline and compared with the drug selection groups based on the CYP2C19 LOF allele. The incremental cost–effectiveness ratio was generally below 50,000 (US$/Qaly), and drug selection based on the CYP2C19 LOF allele was the most cost-effective, followed by universal clopidogrel. Although cardiac genetic and economic data are rudimentary, this review indicates that antiplatelet therapy (drug selection based on the CYP2C19 LOF allele) after PCI is generally cost-effective.

Cost-effectiveness analysis of CYP2C19 genotype-guided antiplatelet therapy for patients with acute minor ischemic stroke and high-risk transient ischemic attack in China. Br J Clin Pharmacol 2024; 90:483-492. [PMID: 37795861 DOI: 10.1111/bcp.15921] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 09/03/2023] [Accepted: 09/28/2023] [Indexed: 10/06/2023] Open
Abstract
AIMS The study aimed to estimate the cost-effectiveness of CYP2C19 genotype-guided antiplatelet therapy using cilostazol and ticagrelor as an alternative to clopidogrel, compared to conventional antiplatelet therapy with clopidogrel and aspirin. METHODS A 90-day decision tree and 30-year Markov model were employed to assess the costs and quality-adjusted life years (QALYs) of personalized antiplatelet therapy for patients with minor ischemic stroke and high-risk transient ischemic attack, compared to conventional antiplatelet therapy in the Chinese healthcare system. The primary outcome was the incremental cost-effectiveness ratio (ICER). The data sources included clinical trials, published literature, official documents and local prices. One-way sensitivity analysis and probabilistic sensitivity analysis were performed to confirm the robustness of the findings. RESULTS The base-case analysis indicated that the CYP2C19 genotype-guided antiplatelet strategy was cost-effective, and cilostazol group and ticagrelor group yielded an ICER of 3327.40 US dollars (USD)/QALY and 3426.92 USD/QALY, respectively, which were less than threshold. The one-way sensitivity analysis showed the results were robust, where the most sensitive parameter was the disability distribution in the modified Rankin scale 3-5. The probabilistic analysis showed that the CYP2C19 genotype-guided antiplatelet therapy with either cilostazol or ticagrelor was 100% cost-effective under the willingness-to-pay threshold. CONCLUSIONS CYP2C19 genotype-guided antiplatelet therapy using cilostazol and ticagrelor as an alternative to clopidogrel appeared to be more cost-effective than conventional antiplatelet therapy for acute minor ischemic stroke and high-risk transient ischemic attack patients over 30 years in China.

Cost-Effectiveness Analysis of Ibuprofen Versus Indomethacin or Paracetamol for the Treatment of Patent Ductus Arteriosus in Preterm Neonates. Curr Probl Cardiol 2023; 48:101751. [PMID: 37088173 DOI: 10.1016/j.cpcardiol.2023.101751] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Accepted: 04/17/2023] [Indexed: 04/25/2023]
Abstract
This was a first-time evaluation that sought to analyze the cost-effectiveness of oral paracetamol and intravenous (IV) indomethacin as alternatives to ibuprofen for PDA in neonates. Decision-analytic, literature-based, economic simulation models were constructed, to follow up the use and consequences of oral/IV ibuprofen versus IV indomethacin, and oral/IV ibuprofen versus oral paracetamol, as first-line therapies for PDA closure. Model outcomes of interest were "success", defined as PDA closure with/without adverse events, or "failure" due to no response to the first course of treatment, death or premature discontinuation of therapy due to adverse events. Oral ibuprofen is dominant/cost-effective over IV indomethacin in 97.9% of simulated cases, but oral paracetamol was 75.2% dominant/cost-effective over oral ibuprofen. Against IV ibuprofen, IV indomethacin was 55.3% dominant/cost-effective, whereas oral paracetamol was dominant/cost-effective in 98.5% of the cases. Sensitivity analyses confirmed the robustness of the study results. For PDA closure, while IV indomethacin was cost-effective against IV ibuprofen, oral paracetamol was cost-effective against both oral and IV ibuprofen.

Abstract
The objective of this study was to evaluate the evidence on cost-effectiveness of pharmacogenetic (PGx)-guided treatment for drugs with Clinical Pharmacogenetics Implementation Consortium (CPIC) guidelines. A systematic review was conducted using multiple biomedical literature databases from inception to June 2021. Full articles comparing PGx-guided with nonguided treatment were included for data extraction. Quality of Health Economic Studies (QHES) was used to assess robustness of each study (0-100). Data are reported using descriptive statistics. Of 108 studies evaluating 39 drugs, 77 (71%) showed PGx testing was cost-effective (CE) (N = 48) or cost-saving (CS) (N = 29); 21 (20%) were not CE; 10 (9%) were uncertain. Clopidogrel had the most articles (N = 23), of which 22 demonstrated CE or CS, followed by warfarin (N = 16), of which 7 demonstrated CE or CS. Of 26 studies evaluating human leukocyte antigen (HLA) testing for abacavir (N = 8), allopurinol (N = 10), or carbamazepine/phenytoin (N = 8), 15 demonstrated CE or CS. Nine of 11 antidepressant articles demonstrated CE or CS. The median QHES score reflected high-quality studies (91; range 48-100). Most studies evaluating cost-effectiveness favored PGx testing. Limited data exist on cost-effectiveness of preemptive and multigene testing across disease states.

Cost-effectiveness analysis of sacubitril/valsartan for reducing the use of implantable cardioverter-defibrillator (ICD) and the risk of death in ICD-eligible heart failure patients with reduced ejection fraction. Curr Probl Cardiol 2022; 47:101385.

Abstract
Although previous cost-effectiveness evaluations of sacubitril/valsartan have demonstrated cardiovascular and economic benefits in heart failure patients with reduced ejection fraction (HFrEF), whether sacubitril/valsartan is cost-effective for reducing the need for implantable cardioverter-defibrillator (ICD) implantation and the risk of death in ICD-eligible patients has not been investigated in patients with HFrEF. Herein, we evaluated the cost-effectiveness of sacubitril/valsartan versus standard of care in reducing the need for ICD implantation and the death rate in HFrEF. A Markov model was developed from the Qatari hospital perspective, comprised of 'survival' and 'death' health states, and was based on 1-monthly Markovian cycles, a 20-years follow-up horizon, and a 3% discount rate. The model inputs were obtained from the literature and local sources. Sacubitril/valsartan resulted in a relative increase of 0.04 quality-adjusted life year (QALY) and 0.67 years of life lived (YLL)/person, with an incremental cost increase of QAR13,952 (USD3,832). Sacubitril/valsartan was associated with incremental cost-effectiveness ratio of QAR341,113 (USD93,687)/QALYs gained and QAR24,431 (USD6,710)/YLL. Sensitivity analyses confirmed robustness, with the cost effectiveness maintained in ≥96.5% of simulated cases. To conclude, sacubitril/valsartan is a cost-effective alternative to standard care against QALY gained and YLL in reducing the need for an ICD therapy and the rate of death among ICD-eligible HFrEF patients.

Abstract
Although studies of non-statin lipid-lowering therapies (NSLLTs) have demonstrated cardiovascular benefits; whether these benefits provide good value has not been evaluated in type 2 diabetes mellitus (T2DM) patients. A systematic review was performed to include studies on the cost-effectiveness of NSLLTs in T2DM patients with/without cardiovascular disease (CVD). Thirteen studies were included; ezetimibe (n=8), proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors (n=4), fenofibrate (n=2), nicotinic acid (n=1), extended-release niacin/laropiprant (ER- ERN/LRPT) (n=1), and icosapent ethyl (n=1). Six studies considered ezetimibe+statin to be a cost-effective compared to statins monotherapy, three studies suggested that PCSK9 inhibitors+statins were not cost-effective compared to statin+ezetimibe. Fenofibrate was a cost-effective either as monotherapy or combined with a statin compared to statin or fenofibrate monotherapy. Nicotinic acid and ER- ERN/LRPT compared to statin monotherapy were also cost-effective. Icosapent ethyl using the solid-state relay was cost-effective compared to standard care but not using the wholesale acquisition cost.
