lthough they atm kinase inhibitor do interact withpotentinhibitors of P-glycoproteinandpotent inhibitors of the cytochrome P450 enzyme CYP3A4.Evidence of principal VTE prevention from clinical trialsThe remainder of this review will focus on the publishedevidence from the clinical trial programmes for dabigatranetexilate, rivaroxaban and apixaban, when it comes to theevaluation of their efficacy and safety for the primaryprevention of VTE in individuals undergoing elective hip andknee replacement surgery.Dabigatran etexilateThree phase III clinical trials that type part of the REVOLUTION? study programme undertaken by BoehringerIngelheim happen to be completed and published on theefficacy and safety of dabigatran etexilate for the primaryprevention of VTE following elective hip and kneereplacement surgery.
The three clinical trials hadidentical non-inferiority study designs with a primaryendpoint of a composite of total VTEand all-cause death during therapy. Theprimary safety outcome was the occurrence of bleedingduring therapy. Key bleeding during the treatmentperiod atm kinase inhibitor was defined as: clinically overt bleeding associatedwith ≥20 g/l fall in haemoglobin; clinically overt bleedingleading to a transfusion of ≥2 units of packed cells or wholeblood; fatal, retroperitoneal, intracranial, intraocular orintraspinal bleeding and bleeding warranting treatmentcessation or top to reoperation. The definition of majorbleeding was consistent with the Committee for ProprietaryMedicinal Products. It is important to note that theassessment of bleeding also included surgical internet site bleeds.
All efficacy and safety outcomes had been assessed by anindependent, central adjudication committee.The RE-NOVATE? hedgehog antagonist I trial randomized 3,494 patientsundergoing total hip replacement surgery to obtain 28–35 days of either dabigatran etexilate, 220 mgor150 mgonce every day, or subcutaneous enoxaparin,40 mgonce every day. The dose of enoxaparinwas equivalent to that utilized routinely within the European Union. The RE-MODEL? trial randomized 2,101 patientsundergoing total knee replacement surgery to obtain 6–10 days of either dabigatran etexilate, 220 mgor150 mgonce every day, or subcutaneous enoxaparin,40 mgonce every day. The third trial, REMOBILIZE?, utilized the North American enoxaparin regimenof 30 mg enoxaparintwice every day, compared witheither dabigatran etexilate, 220 mgor 150 mgonce every day for 12–15 days, in individuals undergoing totalknee replacement surgery.
PARP The follow-up period for thesetrials was 12–14 weeks.In both the RE-NOVATE? I and RE-MODEL? trials,dabigatran etexilate demonstrated non-inferiority with theEU dose of enoxaparinfor the primaryefficacy composite outcome of total VTE and all-causemortality. hedgehog antagonists In RE-NOVATE? I, 6.7%of the enoxaparin group, compared with 6.0%ofthe dabigatran etexilate 220-mg group and 8.6%of the dabigatran etexilate 150-mg group, experienced aprimary efficacy outcome event. Even though therates of the principal efficacy outcome had been higher in theRE-MODEL? trial, as expected for knee replacementsurgery, there had been no considerable differences in between thethree groups: 37.7%of the enoxaparin groupcompared with 36.4%of the dabigatran etexilate220-mg group and 40.5%of the dabigatranetexilate 150-mg group.
In terms of safety, both the RE-NOVATE? I and REMODEL? trials demonstrated comparable key bleeding ratesfor the two dabigatran etexilate groups and also the enoxaparingroup. In RE-NOVATE? I, key bleedingoccurred in 1.6% atm kinase inhibitor of the enoxaparin group, compared with2.0% of the dabigatran etexilate 220-mg group and 1.3% ofthe dabigatran etexilate 150-mg group.Similarly, in RE-MODEL?, key bleeding eventsoccurred in 1.3% of the enoxaparin group, comparedwith 1.5% of the dabigatran etexilate 220-mg group and1.3% of the dabigatran etexilate 150-mg group.In the RE-MOBILIZE? trial, when dabigatran etexilatewas compared with theNorth American dose of enoxaparin, itwas connected with numerically fewer key bleeding events,even though it did not statistically achieve non-inferior efficacy,likely on account of the 50% higher US dose of enoxaparin utilized inthe study and also the prolonged dosing regimen.
In summary, the three clinical trials described abovedemonstrated that dabigatran etexilate was as efficient asthe EU dose of enoxaparinat preventingVTE and all-cause mortality right after total hip or total kneereplacement surgery, but less efficient than the NorthAmerican dose of enoxaparinfollowingknee arthroplasty. The safety profile of dabigatran hedgehog antagonists etexilatewas comparable with that of enoxaparin right after either totalhip or total knee replacement surgery. There had been nosignificant differences in between dabigatran etexilate andenoxaparin when it comes to bleeding outcomes, the incidence ofliver enzyme elevations, and also the incidence of acute coronaryevents either on or off therapy, which suggests there isno rebound activation of coagulation with dabigatran etexilate. A fourth, phase III clinical trial of dabigatran etexilatefor the principal prevention of VTE following elective hipreplacement surgery, RE-NOVATE? II, has recentlybeen c
