This recombinant monoclonal antibody is a research-grade biosimilar of MG1113, targeting tissue factor pathway inhibitor (TFPI)—a multi-Kunitz domain serine protease inhibitor that serves as a key physiological “brake” on the initiation phase of coagulation. TFPI down-regulates the extrinsic pathway by inhibiting factor Xa (FXa) and the tissue factor (TF)–factor VIIa (FVIIa) catalytic complex, thereby limiting thrombin generation; mechanistically, TFPI’s Kunitz-2 domain mediates FXa inhibition, while Kunitz-1 participates in FXa-dependent inhibition of TF–FVIIa.
MG1113 is described as a TFPI-neutralizing monoclonal antibody (IgG4) that binds the second Kunitz domain (Kunitz-2) of TFPI and blocks TFPI function, with the goal of rebalancing coagulation and restoring hemostasis in hemophilia by enhancing TF-driven FXa generation independent of intrinsic pathway factors. This biosimilar provides the antibody component alone, enabling researchers to investigate TFPI biology and extrinsic-pathway regulation, develop/benchmark TFPI-neutralization and coagulation restoration assays, and study mechanistic pharmacology (e.g., TFPI-K2–dependent inhibition relief) in controlled experimental systems relevant to hemophilia research.
