Cifurtilimab  (Synonyms: SEA-CD40)

Cifurtilimab (SEA-CD40) is an agonistic nonfucosylated, human IgG1 monoclonal antibody directed against CD40. Cifurtilimab shows antitumor activities^[1][2].

CD40^[1]

Cifurtilimab has enhanced FcγRIIIa binding (~10x greater than parent IgG1 antibody) that drives increased effector function, resulting in more potent immune stimulatory activity than antibodies with muted or selective FcγR binding^[1].
Cifurtilimab exposure results in a distinct signature of responses including activation of APCs, CD8+ and CD4+ T cells and NK cells, and targeted depletion of CD40+ B cells^[1].
