A Randomized, Open-Label, Study Drug-Dose Blind, Multicenter Study to Evaluate the Efficacy and Safety of JNJ-70033093 (BMS-986177), an Oral Factor XIa Inhibitor, Versus Subcutaneous Enoxaparin in Subjects Undergoing Elective Total Knee Replacement Surgery

Descripción detallada

JNJ-70033093 is an oral anticoagulant for prevention and treatment of thromboembolic events (for example, VTE) that binds and inhibits activated form of human coagulation Factor XI (FXIa) with high affinity and selectivity. The study will consist of 3 phases: up to 30-day screening phase before total knee replacement (TKR) surgery, 10 to14 day postoperative dosing phase, and 4-week follow-up phase. The hypothesis of this study is JNJ-70033093 reduces risk of total VTE during treatment period. The total duration of participation following randomization will be approximately 6 weeks. Efficacy evaluations include unilateral venography assessment of operated leg and assessments of symptomatic DVT, PE, or death. Safety evaluation includes adverse events, clinical laboratory tests, and physical examinations. The safety and efficacy will be monitored throughout the study.
