pirin 81 or 325 mg/day versus open-label warfarinin individuals having a CHADS2 score of 1 or higher.Key bleeding was much more typical in individuals takingdabigatran 300 mg with aspirincomparedwith dabigatran 300 mg alone.Thromboembolism Fostamatinib was only observed in patientsrandomised to dabigatran 50 mg.The RE-LY trial was a large randomised controlledtrial comparing dabigatran with warfarin.102 Itwas a phase III, blinded, noninferiority trial in 18,113patients with nonvalvular AF having a CHADS2 score of1 or higher or who had been older than 65 years with coronaryartery disease.103 Patients had been randomised toeither dabigatran, at a dosage of 110 or 150 mg twicedaily or warfarin titrated to a objective INR of 2–3. The primaryefficacy outcomes from the study integrated strokeor systemic embolism. Efficacy outcomes occurredat 1.
69% per year in individuals assigned to warfarincomparedwith 1.53% within the dabigatran 110-mggroupand 1.11% within the dabigatran 150-mg group. This differencein effect amongst dabigatran 150 mg and warfarinwas discovered to occur at 2 months into the trial andwas carried throughout until trial completion. Thuslow-dose dabigatran was shown to be non-inferior towarfarin and high-dose dabigatran Fostamatinib was shown to besuperior to warfarin. No statistically significant differencewas demonstrated amongst the groups for thesecondary outcome of all-cause mortality. There was, even so, a numericdecrease in both dabigatran groups that approachedsignificance for those receiving dabigatran 150 mg.Key bleeding was the Hedgehog inhibitor primary safety outcome,defined as a reduction in haemoglobin degree of 2 g/dL,transfusion requiring at the very least 2 units of blood, or symptomaticbleeding inside a essential area or organ.
Majorhaemorrhage occurred in 3.36% per year in patientstaking warfarin, 2.71% in low-dose dabigatran, and3.11%/year in high-dose dabigatran 150-mg group.Therefore significant bleeding was much less with 110 mg of dabigatranwhen in comparison to warfarin, HSP and rates of majorhaemorrhage are similar with 150 mg dabigatran andwarfarin. High-dose dabigatran was connected witha significantly elevated risk of significant gastrointestinalhaemorrhagecompared with dabigatran110 mgor warfarin. Even so, allcomposite significant bleeding rates had been discovered to be similarbetween dabigatran 150 mg and warfarin.Discontinuation rates had been 15% for dabigatran110 mg, 16% for dabigatran 150 mg, and 10% forwarfarin after the first year from the trial; and 21% fordabigatran 110 mg, 21% for dabigatran 150 mg, and17% for warfarin at the end from the second year of thetrial.
The primarydriver for this elevated discontinuation of dabigatranwas its propensity to cause dyspepsia: 11.8%for 110 mg and 11.3% Hedgehog inhibitor for 150 mg in comparison to 5.8%for warfarin. Therefore, warfarin was bettertolerated than dabigatran.Dabigatran 150-mg was discovered to have an increasedrate of myocardial infarctionwhen comparedwith warfarin. This effect thattrended towards, but did not reach, statistical significance. It ispossible that the elevated occurrence of myocardialinfarction observed in individuals taking dabigatranin this trial owes much more towards the protective effects ofwarfarin rather than an inherent risk connected withdabigatran therapy.
A meta-analysis comparingwarfarin as well as other therapy regimes showed thatwarfarin was connected with significant reductionin myocardial infarction.A subgroup Fostamatinib analysis from the RE-LY trial investigatedthe safety and efficacy of dabigatran comparedto warfarinwith differing achievements in INRcontrol.105 The study discovered that the time in therapeuticrange did not influence on the original trial’sfindings with regard to efficacy or intracranial haemorrhage.A further subgroup analysis was undertakenin individuals having a history of previous stroke or TIA.106The effects of dabigatran compared with warfarinwere not significantly different in individuals having a previousstroke or TIA in any other outcomes comparedwith other patients—confirming dabigatran’s function insecondary prevention and supporting the findingsof the original RE-LY trial.
An analysis of patientsundergoing cardioversion107 showed the risk of strokeand significant haemorrhage on dabigatran was similar towarfarin.A network meta-analysis compared dabigatranfavourably to antiplatelet therapy:108 dabigatran150 mg reduced Hedgehog inhibitor stroke risk by 63% compared toaspirin alone and 61% in comparison to dual antiplatelettherapy, too as 77% when in comparison to placebo.RivaroxabanThe oral direct factor Xa inhibitor rivaroxaban wascompared to warfarin within the ROCKET-AF study.109This trial was a phase III, randomised, double-blind,event-driven noninferiority trial with over 14,000patients comparing rivaroxaban with warfarin in nonvalvularAFanda history of stroke, TIA, or non-CNS embolism or atleast two independent risk components for future stroke.Enrolment of individuals with out stroke, TIA, or systemicembolism and only two risk components was cappedat 10% from the overall study population; all subsequentlyenrolled individuals had been needed to have atleast three stroke risk components or even a history of stroke,TIA, or systemic embolis
