selectivelyand reversibly inhibits free and prothrombinase-bound Xaactivity without the assistance of antithrombin III.59,60Three phase 2 clinical trials of apixaban happen to be completed.An further study is being performed to evaluateVTE prophylaxis in patients ALK Inhibitors with metastatic cancer.APROPOS. The Apixaban PROhylaxis in Individuals ALK Inhibitors undergOingTotal Knee Replacement Surgery study examined thesafety and efficacy of apixaban following knee arthroplasty.Twelve hundred seventeen patients received apixaban 5, 10,or 20 mg when daily or divided into two doses; enoxaparin30 mg SQ twice daily; or warfarin for 10 to 14 days.61All apixaban groups knowledgeable a significantly reduce incidenceof VTE compared with both enoxaparinandwarfarin, leading to a relative risk reduction of 21%to 69%and 53% to 82%,respectively.
There was no substantial difference betweengroups in terms of bleeding risk; nonetheless, there was a doserelatedincreased risk of bleeding in the apixaban group.61BOTTICELLI–DVT. This mapk inhibitor dose-ranging study comparedapixaban 5 to 10 mg twice daily or 20 mg daily with standardlow-molecular-weight heparin/vitamin K antagonisttherapy for 84 to 91 days as initial treatment foracute symptomatic DVT.62 Standard therapy was defined asenoxaparin 1.5 mg/kg daily, enoxaparin 1 mg/kg twice daily,tinzaparin175 units/kg daily, or fondaparinuxplus either warfarin, phenprocoumon, or acenocoumarol.The main outcomes of recurrent symptomatic VTE orasymptomatic thrombus deterioration, observed by way of ultrasoundor lung profusion scan, were observed in 4.7% of patientsin the apixaban group and 4.
2% in the standard therapygroup. There was no substantial difference in safety outcomes.The study investigators concluded that apixaban exhibits asimilar safety and efficacy profile as standard LMWH/VKAtherapy.62APPRAISE. The Apixaban for PRevention of AcuteIschemic and Safety NSCLC Events dose-ranging study investigatedbleeding risk associated with apixaban versus placebo inpatients with recent STEMI and NSTEMI.63 Four dosing reg-imens were applied initially; nonetheless, the two higherdosing groups withdrew because of excessive bleeding.Outcomes indicated a dose-dependent increase in main or clinicallyrelevant non-major bleeding events.63ADVANCE. Data on apixaban are offered for three phase3 clinical trials, ADVANCE 1, 2, and 3.
64–66 The ApixabanDose orally Versus ANtiCoagulation with Enoxaparinprogram is often a series of studies evaluating apixaban versusenoxaparin following either knee or hip replacement surgery.ADVANCE-1, a non-inferiority trial, compared apixaban 2.5mg twice daily with enoxaparin 30 mg mapk inhibitor twice daily for 10 to 14days in 3,202 patients following knee arthroplasty. Similarefficacy data were noted in both groups.64ADVANCE-2 compared apixaban 2.5 mg twice daily withenoxaparin 40 mg when daily for 10 to 14 days in 3,053 patientswho underwent knee arthroplasty. Apixaban was shown to besuperior to enoxaparinas thromboprophylaxiswith an absolute risk reduction of 9.3% plus a trendtoward much less bleeding.65ADVANCE-3, a double-blind, double-dummy study in 3,866patients, evaluated apixaban 2.5 mg twice daily and enoxaparin40 mg when daily for 35 days.
Apixaban was shown to besuperior to enoxaparinin decreasingthe risk of asymptomatic or symptomatic ALK Inhibitors DVT, nonfatal PE, ordeath, with an absolute risk reduction of 2.5% plus a lowerincidence of bleeding.66The following phase 3 apixaban trials are below way:18? in medically ill patients: ADOPT? as VTE treatment: Apixaban VTE and Apixaban VTEextension? as secondary prevention for those with ACS:APPRAISE 2? as stroke prevention in those with atrial fibrillation:AVERROESand ARISTOTLE.EdoxabanEdoxaban, an oral direct aspect Xa inhibitor, hasbeen evaluated in two phase 2 clinical trials and is now inphase 3. Comparable to the other direct aspect Xa inhibitors described,it really is quickly absorbed, highly selective, inhibits bothfree and clot-bound aspect Xa. It exhibits a dual mode of elimination.Its half-life is nine to 11 hours.
67,68Edoxaban has been evaluated as an selection for mapk inhibitor VTE prophylaxisfollowing orthopedic surgery in two separate phase2 trials. In comparison with placebo, edoxaban reduced VTE incidencefollowing knee replacement surgery without a clinicallysignificant bleeding risk.68,69 Compared with dalteparinfollowing hip arthroplasty, edoxaban showeda 20% reduce incidence of VTE as well as a nonsignificant increasedrisk of bleeding.69,70 In a phase 2 trial involving patientswith atrial fibrillation, once-daily edoxaban was associated withfewer bleeding events compared with twice-daily administration.18ENGAGE-AF TIMI 48. Edoxaban is being evaluated in thephase 3 Efficient aNticoaGulation with Aspect Xa next GEnerationin Atrial Fibrillation trial. Edoxaban 30 to 60 mg oncedaily is being compared with warfarinfor the prevention of stroke and systemic embolic eventsin around 16,500 patients.71Other Aspect Xa InhibitorsSeveral aspect Xa inhibitors are in the early stages of clinicaldevelopment, such as betrixaban, YM-15
