REGN7508 for Preventing Blood Clots After Knee Replacement

This study is looking at an experimental drug, REGN7508, to see how well it prevents blood clots (Venous Thromboembolism or VTE) after total knee replacement surgery. Researchers are comparing REGN7508 to two other common medications, Apixaban and Enoxaparin, and also to a placebo (an inactive substance). The study aims to understand if REGN7508 is effective in preventing these clots and to learn about any side effects it might cause. You might be able to join if you are an adult, 18 years or older, having your first total knee replacement on one side, are in good health, and weigh 130 kg (about 286 lbs) or less. The main goal is to see how many people develop blood clots by about 14 days after surgery. The current status of this study is unclear.
