approximatelyeight-fold risk of VTE compared using the generalpopulation.8,9 VTE, proximal DVT, and fatal VTE occur in10% to 20%, 4% to 5%, and 1% of all individuals hospitalizedfor medical illnesses, respectively.7,10–11 Previous VTE, stroke,heart failure, chronic obstructive.pulmonary disease, sepsis,and bed Afatinib rest are risk variables for VTE in medical individuals.10 Theincidence of VTE in individuals with cancer varies from 4% to20%, and is actually a top cause of death in these individuals.12,13 Therisk of VTE in cancer individuals is higher whilst in hospital formedical illnesses, throughout chemotherapy, and/or surgery.14–16New anticoagulantsNew anticoagulant agents under clinical development havebeen developed employing advanced molecular technology thatenables their effect to be targeted to a selected step or enzymein the coagulation cascade.
17–19 The huge majority of newanticoagulants under clinical development are oral anti-Xaor anti-thrombin agents. Pharmacodynamic features of thenewer anticoagulants are shown in Table 2.A Afatinib number of new anti-Xa and anti-thrombin agents are currentlyunder evaluation for the prophylaxis of VTE in patientsundergoing orthopedic surgery.RivaroxabanThree Phase II, randomized, dose-ranging studies have beenperformed with rivaroxabanin comparison with enoxaparinin individuals undergoingmajor orthopedic surgery. Two studies includedpatients undergoing THR and one study included patientsundergoing TKR.34–36 The principal efficacy endpoint employed inthese studies was the composite of any DVT, confirmed nonfatal PE, and all-cause mortality.
In allstudies treatment was continued until mandatory bilateralvenography 5–9 days after surgery. Depending on the results ofthese studies, the 10 mg as soon as everyday regimen of rivaroxabanwas selected for investigation in Phase III studies.The Everolimus Phase III development plan for rivaroxabancomprised four Phase III clinical trials, recognized as theREgulationof Coagulation in significant Orthopedic surgeryreducing the Risk of DVT and PEstudies,assessing the efficacy and safety of rivaroxaban 10 mg oncedaily compared with enoxaparin offered at US or Europeandoses. The principal composite efficacy endpoint of theRECORD studies was any DVT, nonfatal PE, or death fromany lead to. The RECORD 1 and RECORD 3 studies showedthat rivaroxaban started postoperatively was significantlymore successful than enoxaparin started preoperatively inpatients undergoing THR and TKR.
37–38 The absolute riskreduction on the principal endpoint was 2.6% at 36 days inRECORD 1 and 9.2% at two weeks in RECORD 3, withsimilar safety profiles. In RECORD 2, extendedprophylaxis with rivaroxaban was compared with HSP shorttermprophylaxis with enoxaparin in patientsundergoing THR.39 As expected, the study showed thatextended prophylaxis with rivaroxaban is superior to shorttermprophylaxis with enoxaparin in individuals undergoingTHR, with no safety concerns. In RECORD 4, rivaroxabanwas compared with enoxaparin, both started postoperativelyand continued for 10–14 days in individuals undergoingTKR.40 Rivaroxaban was significantly much more successful thanenoxaparinin patientsundergoing TKR. Main bleeding occurred in 0.7% patientsrandomized to rivaroxaban and in 0.3% individuals randomizedto enoxaparin.
A pooled analysis on the four RECORD studies has beenperformed to assess the clinical benefit Everolimus of rivaroxaban comparedwith enoxaparin when it comes to challenging clinical endpoints.The analysis showed that rivaroxaban is much more effectivethan enoxaparin for the prevention of symptomatic VTEand all-cause death in individuals undergoing significant orthopedicsurgery, irrespective of age, weight, gender, or renalfunction.41 Rivaroxaban decreased the composite endpoint ofsymptomatic VTE, cardiovascular events, all-cause mortality,and significant bleeding significantly more than enoxaparin. A similar effect was observed within the incidenceof symptomatic VTE and/or death at 10–14 daysand for the total study duration. Even so, rivaroxaban wasassociated with a higher incidence of significant bleeding thanenoxaparin at 10–14 daysand for thetotal study duration.
42 Further studiesshould address the concern on the cardiovascular reboundphenomenon to establish the safety of rivaroxaban.43 Basedon the results on the RECORD studies, rivaroxaban has beenrecently licensed for the prevention of VTE after electivehip and knee replacement in Europe and Canada. A PhaseIV clinical trial Afatinib is ongoing to assess further Everolimus informationon the risk-benefit profile of rivaroxaban.ApixabanApixaban was compared with enoxaparinand warfarinin a dose-finding study in 1238patients undergoing TKR.44 All apixaban groups had lowerprimary efficacy event ratesthan either comparator. Depending on these final results,apixaban 2.5 mg twice everyday was selected for Phase IIIdevelopment.Three Phase III trials have been developed to explore theefficacy and safety of apixaban for the prevention of thromboembolismafter significant orthopedic surgery. The principal efficacy outcome of these studieswas the composite of DVT, PE, and death from any lead to throughout thetreatment period. In
