Proof-of-concept trials confirm robust anti-clotting effects for Regeneron's two mechanistically-distinct antibodies against factor XI, in patients undergoing total knee replacement
Trial results consistent with prospective design of these antibodies to have distinct profiles – one to provide stronger anticoagulation and the other to have a lower risk of bleeding – potentially allowing physicians to tailor anticoagulant therapy for patients with different risk profiles
Phase 3 trials in patients undergoing total knee replacement initiated as part of broad factor XI program evaluating the two antibodies across a range of patient populations and clinical settings
