selectivelyand reversibly inhibits free and prothrombinase-bound Xaactivity without the assistance of antithrombin III.59,60Three phase 2 clinical trials of apixaban have been completed.An further study is being conducted to evaluateVTE prophylaxis in patients ALK Inhibitors with metastatic cancer.APROPOS. The Apixaban PROhylaxis in Patients 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 once daily or divided into two doses; enoxaparin30 mg SQ twice daily; or warfarin for 10 to 14 days.61All apixaban groups experienced a considerably reduced incidenceof VTE compared with both enoxaparinandwarfarin, leading to a relative danger reduction of 21%to 69%and 53% to 82%,respectively.
There was no substantial difference betweengroups when it comes to bleeding danger; however, there was a doserelatedincreased danger 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 therapy 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 via 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 regular LMWH/VKAtherapy.62APPRAISE. The Apixaban for PRevention of AcuteIschemic and Safety NSCLC Events dose-ranging study investigatedbleeding danger related to apixaban versus placebo inpatients with recent STEMI and NSTEMI.63 Four dosing reg-imens were employed initially; however, the two higherdosing groups withdrew due to excessive bleeding.Final results indicated a dose-dependent boost in major or clinicallyrelevant non-major bleeding events.63ADVANCE. Data on apixaban are obtainable for three phase3 clinical trials, ADVANCE 1, 2, and 3.
64–66 The ApixabanDose orally Versus ANtiCoagulation with Enoxaparinprogram is 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 once daily for 10 to 14 days in 3,053 patientswho underwent knee arthroplasty. Apixaban was shown to besuperior to enoxaparinas thromboprophylaxiswith an absolute danger reduction of 9.3% along with a trendtoward less bleeding.65ADVANCE-3, a double-blind, double-dummy study in 3,866patients, evaluated apixaban 2.5 mg twice daily and enoxaparin40 mg once daily for 35 days.
Apixaban was shown to besuperior to enoxaparinin decreasingthe danger of asymptomatic or symptomatic ALK Inhibitors DVT, nonfatal PE, ordeath, with an absolute danger reduction of 2.5% along with a lowerincidence of bleeding.66The following phase 3 apixaban trials are under way:18? in medically ill patients: ADOPT? as VTE therapy: 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 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. Compared to placebo, edoxaban decreased VTE incidencefollowing knee replacement surgery without a clinicallysignificant bleeding danger.68,69 Compared with dalteparinfollowing hip arthroplasty, edoxaban showeda 20% reduced incidence of VTE in addition to a nonsignificant increasedrisk of bleeding.69,70 Inside a phase 2 trial involving patientswith atrial fibrillation, once-daily edoxaban was related withfewer bleeding events compared with twice-daily administration.18ENGAGE-AF TIMI 48. Edoxaban is being evaluated in thephase 3 Productive aNticoaGulation with Factor 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 approximately 16,500 patients.71Other Factor Xa InhibitorsSeveral aspect Xa inhibitors are in the early stages of clinicaldevelopment, such as betrixaban, YM-15
