Glembatumumab 

Glembatumumab is a fully human IgG2 monoclonal antibody directed against the extracellular structural domain of GPNMB expressed in human breast cancer and melanoma. Glembatumumab can be coupled to the microtubule inhibitor monomethyl auristatin E to form glembatumumab vedotin. Glembatumumab vedotin is an antibody-agent coupling (ADC) with antitumor activity^[1].

Glembatumumab vedotin (CR011-vcMMAE) (0-2.5 μg/mL, 72 h) shows little growth inhibition in UACC62 melanoma cells without MEK inhibitor pretreatment at a concentration of 0.16 μg/mL, while the same dose of CR011-vcMMAE shows stronger growth inhibition in UACC62 cells pretreated with MEK inhibitor^[3].

Glembatumumab vedotin (i.v., 2.5 mg/kg, 3 times in 7 days) can inhibit tumor growth and is well tolerated in CB17SC scid ^/ female mice with sarcomas^[2].
