the ADVANCE 1 trial apixaban did notmeet the criteria for noninferiority compared with enoxaparinfor ALK Inhibitor prevention of VTE in individuals undergoing TKR.45The major efficacy outcome occurred in 9% of patientsin the apixaban group and in 8.8% in the enoxaparin group.Big or clinically relevant nonmajor bleeding occurred in2.9% of individuals in the apixaban group and in 4.3% in theenoxaparin group. Big bleeding occurred in0.7% of individuals in the apixaban group and in 1.4% in theenoxaparin group.In the ADVANCE 2 trial apixaban was compared withenoxaparin in individuals undergoing TKR.46 The incidence ofthe major efficacy outcome was 15.1% in the apixabangroup and 24.4% in the enoxaparin group. Proximal DVT, symptomatic nonfatalPE, and VTE-related death occurred in 1.1% of individuals givenapixaban and in 2.
2% of individuals offered enoxaparin. Clinically relevant bleedingoccurred in 3.5%and 4.8% on the individuals offered apixaban and enoxaparin,respectively. A Phase III randomized, double-blindstudy has been recently completed aimed at assessing therelative efficacy and safety of apixaban and enoxaparin for35 ALK Inhibitor days in individuals undergoing elective THR surgery.New anti-Xa in Phase II trialsThe oral anti-Xa betrixaban has been compared withenoxaparin, both started postoperatively in individuals undergoingTKR.47 DVT on mandatory unilateral venography orsymptomatic proximal, or PE was reported by means of to day14 in 20%, 15%, and 10% of individuals receiving increasingdoses of betrixaban or enoxaparin, respectively. No bleedingcomplications were reported in the betrixaban 15 mggroup. Big bleeding occurred in 2.
3% of individuals in theenoxaparin group.Two Phase II studies have explored the efficacy and safetyof edoxaban for the prevention of VTE in major orthopedicsurgery. Edoxaban decreased the incidence of VTE in a dosedependentfashion in comparison with placebo, without having asignificant enhance CDK inhibitors in bleeding complications in patientsundergoing TKR.48 Edoxaban was compared with dalteparinin individuals undergoing THR.49 VTE occurred in 43.3% ofpatients in the dalteparin group and in 28.2%, 21.2%, 15.2%,and 10.6% of individuals receiving edoxaban, respectively. Nobleeding was reported in the dalteparin group. The incidenceof major or clinically considerable nonmajor bleeding in theedoxaban groups ranged from 1.6% with reduce doses to 2.3%for higher doses.
The efficacy and safety of YM150 for the preventionof VTE in individuals undergoing THR was investigated in aPhase II study.27 Individuals were randomized to once-dailyYM150 starting 6–10 hours soon after hip replacement or toreceive subcutaneous enoxaparin for 7–10 days. A significantdose-related trend in the incidence of VTEwas observed with YM150. Threeclinically relevant nonmajor PARP bleedings were observed, one inthe 3 mg and two in the 10 mg YM150 dose groups. ThePhase II ONYX-2 study confirmed a considerable decreasein the incidence of DVT, symptomatic VTE, PE, and deathwith increasing doses of YM150 in individuals undergoingTHR surgery.50 A variety of Phase II and Phase III studieshave been designed testing this agent, of which some arecompleted and some are at present ongoing.
The aim of thesestudies is usually to evaluate the efficacy and safety of different dosesof YM150 for the prevention of VTE in individuals undergoingmajor orthopedic surgery CDK inhibitors in comparison with enoxaparin orwarfarin.The oral anti-Xa razaxaban has been compared with twicedaily 30 mg enoxaparin in individuals undergoing elective kneesurgery.29 Razaxaban was effective at any evaluated dosage,but highest doses were connected with much more bleedingsthan enoxaparin. No further study has been conducted withrazaxaban.In individuals undergoing THR or TKR, prophylaxis withLY517717 resulted in a dose-dependent decrease in theincidence of VTE. The incidences of general, symptomatic,or asymptomatic VTE was 19%, 19%, and 16% withincreasing doses of LY517717, respectively, comparedwith 21% for enoxaparin.
All the doses of LY517717 metthe predefined criteria for noninferiority compared withenoxaparin for the prevention ALK Inhibitor of VTE soon after TKR or THR,with similar rates of bleeding complications.28 No studiesare at present ongoing with this agent in individuals undergoingorthopedic surgery.In a dose-finding study, the efficacy of distinct dosesof eribaxaban has been compared with that of enoxaparinin individuals undergoing TKR.30 VTE occurred in 37%, 37%,29%, 19%, 14%, 1.4%, and 11% of individuals receivingincreasing doses of eribaxaban, respectively, compared with18% of individuals receiving enoxaparin. This study showed anonsignificant dose-related enhance in the incidence of totalbleeding, primarily accounted for by minor bleeding.A dose-finding study is at present underway to assess theefficacy and safety of TAK-442 in comparison with enoxaparinfor the prevention of VTE soon after TKR. A Phase II study has also beendesigned to assess the efficacy and safety of GW813893 inthe prophylaxis of VTE following TKR..In a Phase II study, 690 individuals undergoing TKRsurgery were randomized to AVE5026 or CDK inhibitors enoxaparin.32A
