AREA DRUG & THERAPEUTICS BULLETIN

1 Update from Fife Area Drug and Therapeutics Committee December 2011-March 2012 AREA DRUG & THERAPEUTICS BULLETIN Prescribing of Newer Oral Anticoagulants There are now 2 newer oral anticoagulants, dabigatran and rivaroxaban, that have been licensed and approved for use by the Scottish Medicines Consortium (SMC) 1,2 for use as alternatives to warfarin for the prevention of stroke in non-valvular atrial fibrillation (AF). Both drugs should only be prescribed in line with previous advice issued by Healthcare Improvement Scotland (HIS) 3 i.e. only in patients who have true intolerance to warfarin and other coumarins and in those who continue to have poor INR control even though they are complying with their warfarin treatment. Rivaroxaban Efficacy Rivaroxaban is direct factor Xa inhibitor which prevents the formation of thrombin. The key evidence to support the use of rivaroxaban for this indication comes from the Rocket-AF study which was a randomised, double-blind, double-dummy, phase 3 study comparing rivaroxaban 20mg v warfarin in patients with non-valvular AF and considered to be at moderate to high risk of stroke. The study found that rivaroxaban was non-inferior to warfarin in preventing stroke or systemic embolism. Safety There was no difference in major and non-major bleeding between rivaroxaban and warfarin. However, rivaroxaban was found to cause signifi cantly more GI bleeding but signifi cantly less fatal bleeding or intracranial haemorrhage. A lower dose of rivaroxaban (15mg) should be used in patients with moderate renal impairment. There is no specifi c antidote to rivaroxaban. Cost p.a. Rivaroxaban 20mg daily 764 Warfarin depending on dose. Dabigatran Efficacy Dabigatran is a direct thrombin inhibitor. The key evidence to support the use of dabigatran comes from the RE-LY study which was a phase 3, multi-centre study comparing 2 different doses of dabigatran (150mg,110mg) v open label warfarin. Dabigatran 110mg twice daily was shown to be non-inferior to warfarin in the prevention of stroke and systemic embolism, while dabigatran 150mg was shown to be superior to warfarin (although the absolute difference was small - 0.6%). Dabigatran was found to be more effective where patients had poorer INR control with warfarin. Safety The overall major bleeding rate was lower in both dabigatran groups than in warfarin but was only statistically signifi cant with the lower 110mg dose of dabigatran. GI bleeding was numerically higher in both dabigatran groups compared to warfarin and was statistically higher with the dabigatran 150mg dose. The rate of bleeding with dabigatran was found to increase with increasing age and was highest in patients aged over 80 years. More patients experienced dyspepsia with dabigatran than with warfarin. Dabigatran is contraindicated in patients with severe renal impairment. A lower dose of dabigatran (110mg) should be used in patients with moderate renal impairment. There is no specifi c antidote to dabigatran. Cost p.a. Dabigatran 110mg or 150mg twice daily 917* Warfarin depending on dose.

2 Local Preference There is no comparative data to review the effi cacy of dabigatran v rivaroxaban. Although the trials had similar end-points the methodologies were different.the ADTC have considered all the evidence for both agents and have decided that rivaroxaban should be the preferred agent in Fife due to the following factors approved for the prevention of DVT. Local guidance is currently being developed providing advice to prescribers on how to convert patients from rivaroxaban/ dabigatran to warfarin/parenteral anticoagulants and vice-versa. The guidance will also advise how to manage bleeding with the newer anticoagulants in both primary and secondary care settings. Key Messages 1. Warfarin remains the preferred oral anticoagulant agent. 2. Rivaroxaban is the preferred newer oral anticoagulant for the prevention of stroke in patients with non-valvular AF. 3. Rivaroxaban should only be considered in patients who are truly intolerant of warfarin or other coumarins and only in patients who have poor INR control even though they have good compliance with their warfarin therapy. 4. Overall the effi cacy of rivaroxaban and dabigatran is non-inferior to warfarin. Both agents cause more GI bleeding than warfarin. 5. The newer agents are considerably more expensive than warfarin even when taking into account additional monitoring costs with warfarin. 6. There is concern about the lack of antidote with the newer agents if a patient was to present with a life-threatening haemorrhage or require emergency surgery. *Price correct as of March References 1.
