Quantitative Model-Informed Dose Selection for a Milvexian Phase III Study in Patients With Atrial Fibrillation.

ABSTRACT: Milvexian, an activated factor XI inhibitor, is being evaluated in the LIBREXIA phase III program for the prevention of thrombotic events, including in patients with atrial fibrillation (LIBREXIA AF). To guide the selection of a phase III dose regimen for LIBREXIA AF, two main approaches were used: (1) population pharmacokinetics and exposure-response modeling of milvexian phase I and phase II (AXIOMATIC-TKR) study data was performed to characterize the relationship between milvexian population pharmacokinetics and clinical efficacy, safety, and coagulation biomarkers; and (2) a model-based meta-analysis was developed using published clinical trial data from comparator anticoagulants in total hip or knee replacement patients. When used to simulate exposures for an atrial fibrillation popul
