1. CPIC Guideline for warfarin and CYP2C9,VKORC1

Summary

The best way to estimate the anticipated stable dose of warfarin is to use the algorithms available on http://www.warfarindosing.org 

Annotation

November 2013 Update

CPIC guideline authors are aware of several recently published studies on warfarin pharmacogenetics [Articles:24251361, 24251363, 24251360]. These papers have prompted several opinion pieces [Articles:24328463, 24251364]. The authors are evaluating the information, which will be incorporated into the next update of the CPIC guideline on warfarin.

October 2011

Advance online publication September 2011.

  • Guideline regarding the use of pharmacogenomic tests in dosing for warfarin was published in Clinical Pharmacology and Therapeutics by the Clinical Pharmacogenetics Implementation Consortium (CPIC).
  • These guidelines are applicable to:
    • adult patients
  • Excerpt from the 2011 warfarin dosing guideline:
    • "Pharmacogenetic algorithm-based warfarin dosing: Numerous studies have derived warfarin dosing algorithms that use both genetic and non-genetic factors to predict warfarin dose [Articles:18305455, 19228618, 18574025]. Two algorithms perform well in estimating stable warfarin dose across different ethnic populations; [Articles:18305455, 19228618] these were created using more than 5,000 subjects. Dosing algorithms using genetics outperform nongenetic clinical algorithms and fixed-dose approaches in dose prediction [Articles:18305455, 19228618]. The best way to estimate the anticipated stable dose of warfarin is to use the algorithms available on http://www.warfarindosing.org (offering both high-performing algorithms [Articles:18305455, 19228618]). The dosing algorithm published by the International Warfarin Pharmacogenetics Consortium is also online, at IWPC Pharmacogenetic Dosing Algorithm. The two algorithms provide very similar dose recommendations."
    • "Approach to pharmacogenetic-based warfarin dosing without access to dosing algorithms: In 2007, the FDA modified the warfarin label, stating that CYP2C9 and VKORC1 genotypes may be useful in determining the optimal initial dose of warfarin [Article:17906972]. The label was further updated in 2010 to include a table (Table 1) describing recommendations for initial dosing ranges for patients with different combinations of CYP2C9 and VKORC1 genotypes. Genetics-based algorithms also better predict warfarin dose than the FDA-approved warfarin label table [Article:21272753]. Therefore, the use of pharmacogenetic algorithm-based dosing is recommended when possible, although if electronic means for such dosing are not available, the table-based dosing approaches (Table 1) are suggested. The range of doses by VKORC1 genotype and the range of dose recommendations/predictions by the FDA table and algorithm are shown in Figure 2."

Figure 2. Frequency histograms of stable therapeutic warfarin doses in mg/week, stratified by VKORC1 -1639G>A genotype.

Adapted from Figure 2 of the 2011 guideline manuscript

Figure 2 Legend: Frequency histograms of stable therapeutic warfarin doses in mg/week, stratified by VKORC1 -1639G>A genotype in 3,616 patients recruited by the International Warfarin Pharmacogenetics Consortium (IWPC) who did not carry the CYP2C9*2 or *3 allele (i.e., coded as *1/*1 for US Food and Drug Administration (FDA) table and algorithm dosing). The range of doses within each genotype group recommended on the FDA table is shown via the shaded rectangle. The range of doses predicted using the IWPC dosing algorithm in these 3,616 patients is shown by the solid lines.

Figure 2 demonstrates that the range of individuals covered by the FDA table is much narrower than that of the algorithm. The article and supplement detail important variables that are not covered by the table that should also be taken into consideration.

Description

An anticoagulant that acts by inhibiting the synthesis of vitamin K-dependent coagulation factors. Warfarin is indicated for the prophylaxis and/or treatment of venous thrombosis and its extension, pulmonary embolism, and atrial fibrillation with embolization. It is also used as an adjunct in the prophylaxis of systemic embolism after myocardial infarction. Warfarin is also used as a rodenticide.

Pharmacogenetics

Warfarin is one of the most widely prescribed anticoagulant drugs worldwide. It is used to prevent thromboembolic diseases in patients with deep vein thrombosis, atrial fibrillation, recurrent stroke or heart valve prosthesis [Article:16960144]. Warfarin, as do other coumarin-type drugs with similar mechanisms of action, acts as an inhibitor of VKORC1; this leads to a reduced amount of Vitamin K available to serve as a cofactor for clotting proteins [Article:14765194]. Although effective, warfarin dosing is challengIng due to its narrow therapeutic index and high degree of inter-individual variability in optimal dosing (between 0.6 and 15.5 mg/day) [Articles:11926893, 12931134, 15930419, 16888441]. Inappropriate dosing of warfarin has been associated with a substantial risk of both major and minor hemorrhage [Articles:16888441, 16960144, 16983400].

Pharmacokinetics

Warfarin is a natural product and is administered as racemic mixture of the R and S stereoisomers of the drug. S-warfarin is 3-5 times more potent an inhibitor of the vitamin K epoxide reductase complex, the target of action, than R-warfarin [Article:3567019]. The stereoisomers are metabolized by different phase 1 enzymes; the predominant metabolism of the S isomer is via CYP2C9, whereas the metabolism of R-warfarin is mainly via CYP3A4 with involvement of CYP1A1, CYP1A2, CYP2C8, CYP2C9, CYP2C18 and CYP2C19 [Articles:1581537, 11353757, 8689941, 8723744] as depicted in the warfarin PK pathway (http://pharmgkb.org/pathway/PA145011113). Phase 2 metabolism of warfarin has not been well studied and is not depicted in this pathway representation, although it is known that sulfated and glucuronyl conjugates can be formed [Article:1732719]. Elimination is predominantly renal however warfarin has been shown to interact with the ABCB1 transporter in liver [Article:1467682].

Pharmacodynamics

Warfarin exerts its anticoagulant effect through inhibition of its target Vitamin K epoxide reductase (VKORC1) [Article:14765194]. The two enantiomers of warfarin are both able to inhibit VKORC1, although with different potencies. The mechanism of action of warfarin is depicted in the Warfarin Pharmacodynamics Pathway (http://pharmgkb.org/pathway/PA145011114). VKORC1 catalyzes the conversion of oxidized Vitamin K to reduced Vitamin K with the help of microsomal epoxide hydrolase (EPHX1). Treatment of warfarin blocks this reaction, which leads to a reduction in the pool of reduced Vitamin K that is needed as a cofactor for clotting proteins. The downstream genes influenced by the form of Vitamin K are also depicted in the pathway. The product of these target genes are postranslationally carboxylated to become Gla-containing proteins by gamma-glutamyl carboxylase (GGCX). Gla-containing proteins are involved in hemostasis (coagulation factors F2, F7, F9, F10, Protein C, S and Z) as well as bone metabolism (BGLAP), tissue matrix (MGP) and apoptosis (GAS6) [Articles:16983400, 18752379, 18698879]. The endoplasmic reticulum chaperone protein calumenin (CALU ) can bind to the vitamin K cycle and inhibit its activity [Article:15075329].

Pharmacogenetics

Warfarin pharmacogenetics is considered a classical example of pharmacogenetics. Many studies have attempted to explain the factors that influence warfarin response [Articles:16722840, 16960144, 17161452]. Candidate genes from both the PK and PD pathways have been the subjects of investigation for their potential pharmacogenetic relevance. Overall, VKORC1 polymorphisms account for ~30% of the variance in stabilized warfarin dose and many studies have consistently demonstrated that VKORC1 genotype appears to be the single biggest predictor of warfarin dose [Articles:20203262, 19228618, 17161452, 18535201, 18574025, 18183038]. About 40% of dose variance could be explained taking into consideration both VKORC1 and CYP2C9 genetic polymorphisms. Accounting for genetic variation in both VKORC1 and CYP2C9, age, height, body weight, interacting drugs, and indication for warfarin therapy explained about 55% of the variability in warfarin dose [Article:17042764]. Many studies have attempted to define a warfarin dosing algorithm that takes into account both genetic and non-genetic factors in order to predict an optimal warfarin dose [Articles:19228618, 17042764, 18305455]. An online warfarin dosing algorithm is available online at http://www.warfarindosing.org/Source/Home.aspx to help doctors and other clinicians begin warfarin therapy by estimating the therapeutic dose in patients new to warfarin. In 2007, pharmacogenomic information for warfarin was approved by FDA to be included in the product label stating that VKORC1 and CYP2C9 genotypes may be useful in determining the optimal initial dose of warfarin [Article:17906972]. The warfarin label was updated again in 2010 to include specific CYP2C9 and VKORC1 variant information and a summary table describing the range of stable maintenance doses observed in multiple patients having different combinations of CYP2C9 and VKORC1 gene variants (http://www.pharmgkb.org/clinical/10879145.pdf). Genetic testing was recommended by FDA prior to initiating treatment with warfarin (http://pharmgkb.org/drug/PA451906#tabview=tab0&subtab=32).

The 3 most important variants shown to have clinical implications for warfarin dosing and prevention of adverse events are the G-1639A polymorphism (rs9923231) of VKORC1 and *2 (rs1799853), *3 (rs1057910) alleles of CYP2C9. The VKORC1:G-1639A polymorphism is a polymorphism in the promoter region of VKORC1 and associated with lower dose requirements for warfarin in Caucasian and Asian patients [Articles:15888487, 18305455, 20203262, 19228618, 17161452, 18535201, 18574025, 18183038]. Individuals with the CYP2C9*2 and *3 variants are more likely to need lower doses of warfarin, take a longer time to reach target INR on starting warfarin therapy and have an increased risk of bleeding complications [Articles:10073515, 11926893]. Several other polymorphisms in CYP2C9 have been reported some of which have also been shown to effect warfarin metabolism (*4, [Article:12621390]; *5, [Article:11455026]; *11, [Article:15970795]). A variant of CYP4F2 (rs2108622) has been shown to be associated with warfarin dose [Article:18250228]. Recently, a new variant (rs339097) in VKORC1 regulator gene calumenin (CALU) has been identified that predicts higher warfarin dose in African Americans populations, with the G allele of (rs339097) associated with 14.5% higher therapeutic warfarin dose [Article:20200517]. Further information on variants affecting warfarin response is available on the warfarin PGx research page (http://pharmgkb.org/drug/PA451906#tabview=tab1&subtab=32).

Pharmacology, Interactions, and Contraindications

Mechanism of Action

Warfarin inhibits vitamin K reductase, resulting in depletion of the reduced form of vitamin K (vitamin KH2). As vitamin K is a cofactor for the carboxylation of glutamate residues on the N-terminal regions of vitamin K-dependent proteins, this limits the gamma-carboxylation and subsequent activation of the vitamin K-dependent coagulant proteins. The synthesis of vitamin K-dependent coagulation factors II, VII, IX, and X and anticoagulant proteins C and S is inhibited. Depression of three of the four vitamin K-dependent coagulation factors (factors II, VII, and X) results in decreased prothrombin levels and a decrease in the amount of thrombin generated and bound to fibrin. This reduces the thrombogenicity of clots.

Pharmacology

Warfarin, a coumarin anticoagulant, is a racemic mixture of two active isomers. It is used in the prevention and treatment of thromboembolic disease including venous thrombosis, thromboembolism, and pulmonary embolism as well as for the prevention of ischemic stroke in patients with atrial fibrillation (AF).

Absorption, Distribution, Metabolism, Elimination & Toxicity

Biotransformation

Metabolized stereo- and regio-selectively by hepatic microsomal enzymes. S-warfarin is predominantly metabolized by cytochrome P450 (CYP) 2C9 to yield the 6- and 7-hydroxylated metabolites. R-warfarin is metabolized by CYP1A1, 1A2, and 3A4 to yield 6-, 8-, and 10-hydroxylated metabolites. Hydroxylated metabolites may be further conjugated prior to excretion into bile and urine. UGT1A1 appears to be responsible for producing the 6-O-glucuronide of warfarin, with a possibly contribution from UGT1A10. Five UGT1As may be involved in the formation of 7-O-glucuronide warfarin. S-warfarin has higher potency than R-warfarin and genetic polymorphisms in CYP2C9 may dramatically decrease clearance of and increase toxicity of the medication.
