Letolizumab  (Synonyms: BMS-986004)

Letolizumab (BMS-986004) is a monoclonal antibody targeting CD40L, which is produced to express mutant IgG1 lacking effector function, including Fc binding and complement fixation. Letolizumab reduces rejection, thromboembolism and prolongs the survival time^[1][2][3].

Letolizumab inhibits the viability of CD40L trimer and CHO-CD40L in human B cell (IC₅₀ values of 3.6 nM and 1.3 nM, respectively) or nonhuman primate B cell (IC₅₀ values of 3.8 nM and 7.3 nM, respectively)^[2].
Letolizumab (2, 10 and 20 mg/kg; i.v.; once a week for 10 weeks) prolongs the survival time of rhesus macaques after renal transplantation^[2].
