lthough they do interact withpotentinhibitors of P-glycoproteinandpotent inhibitors on the cytochrome P450 enzyme CYP3A4.Evidence of primary VTE prevention from clinical trialsThe remainder of this overview will focus on the publishedevidence from the clinical ALK Inhibitors trial programmes for dabigatranetexilate, rivaroxaban and apixaban, in terms of theevaluation of their efficacy and safety for the primaryprevention of VTE in patients undergoing elective hip andknee replacement surgery.Dabigatran etexilateThree phase III clinical trials that form part of the REVOLUTION? study programme undertaken by BoehringerIngelheim have been 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 ALK Inhibitors hadidentical non-inferiority study designs having a primaryendpoint of a composite of total VTEand all-cause death during therapy. Theprimary safety outcome was the occurrence of bleedingduring therapy. Major bleeding during the treatmentperiod 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 leading to reoperation. The definition of majorbleeding was consistent with all the Committee for ProprietaryMedicinal Goods. It is important to note that theassessment of bleeding also integrated surgical internet site bleeds.
All efficacy and safety outcomes were assessed by anindependent, central adjudication committee.The RE-NOVATE? I trial mapk inhibitor 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 used 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?, used 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 patients undergoing totalknee replacement surgery.
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 NSCLC and all-causemortality. 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. Though therates on the primary efficacy outcome were greater in theRE-MODEL? trial, as expected for knee replacementsurgery, there were no significant differences among 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 similar main bleeding ratesfor the two dabigatran etexilate groups and also the enoxaparingroup. In RE-NOVATE? I, main bleedingoccurred in mapk inhibitor 1.6% on the enoxaparin group, compared with2.0% on the dabigatran etexilate 220-mg group and 1.3% ofthe dabigatran etexilate 150-mg group.Similarly, ALK Inhibitors in RE-MODEL?, main bleeding eventsoccurred in 1.3% on the enoxaparin group, comparedwith 1.5% on the dabigatran etexilate 220-mg group and1.3% on 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 main bleeding events,although it did not statistically achieve non-inferior efficacy,likely as a result of the 50% greater US dose of enoxaparin used inthe study and also the prolonged dosing regimen.
In summary, the three clinical trials described abovedemonstrated that dabigatran etexilate was as powerful asthe EU dose of enoxaparinat preventingVTE and all-cause mortality right after total hip or total kneereplacement surgery, but much less powerful than the NorthAmerican dose of enoxaparinfollowingknee arthroplasty. The safety mapk inhibitor profile of dabigatran etexilatewas comparable with that of enoxaparin right after either totalhip or total knee replacement surgery. There were nosignificant differences among dabigatran etexilate andenoxaparin in terms of 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 primary prevention of VTE following elective hipreplacement surgery, RE-NOVATE? II, has recentlybeen c
