Frovocimab  (Synonyms: LY 3015014)

Frovocimab (LY 3015014) is a humanized IgG4 monoclonal antibody (mAb) that neutralizes PCSK9. Frovocimab inhibits PCSK9 binding to LDL receptor (LDLR) while permitting the normal proteolytic cleavage of the bound intact PCSK9^[1].

Frovocimab (LY 3015014) binds to intact but not truncated PCSK9. The selective binding of Frovocimab to intact PCSK9 is related to its binding epitope, the linear sequence of amino acids 160-181 of the catalytic domain of human PCSK9, which is absent in truncated PCSK9. Frovocimab inhibits PCSK9 binding to LDLR while permitting the normal proteolytic cleavage of the bound intact PCSK9. Additionally, upon cleavage, truncated inactive PCSK9 is released from Frovocimab^[1].

Frovocimab (LY 3015014; 10 mg/kg; i.v; once) causes significant PCSK9 accumulation, its duration of LDL lowering is reduced, and its clearance (CL) from serum is accelerated in mice expressing a noncleavable variant of human PCSK9^[1].
Frovocimab (LY 3015014; 5 mg/kg; i.v; once) decreases LDL cholesterol in monkeys and, unlike other PCSK9 mAbs, does not cause an accumulation of intact PCSK9 in serum^[1].
