In vitro

MEDI4736 is a potent antagonist of PD-L1 function, blocking interaction with PD-1 and CD80 to overcome inhibition of primary human T-cell activation. It does not trigger antibody-dependent cellular cytotoxicity (ADCC)[2].

In vivo In vivo MEDI4736 significantly inhibits the growth of human tumors in a novel xenograft model containing coimplanted human T cells[2]. In patients with advanced solid tumors, The linear clearance, volume of distribution and concentration at half maximal elimination (KM) of MEDI4736 are 240 mL/day, 3.6 L and 0.4 μg/mL, respectively. The half-life is ~23 days at doses ≥ 3 mg/kg Q2W. Greater than 99% target saturation (soluble and membrane bound) is expected at ≥40 μg/mL of MEDI4736[3].
