生物活性:
Enavatuzumab (PDL192; ABT-361) is a humanized IgG1 monoclonal antibody targeting the receptor of TNF-like weak inducer of apoptosis (TWEAK). TWEAK (Fn14; TNFRSF12A), the natural ligand of the TWEAK receptor (TweakR), stimulates multiple cellular responses. Enavatuzumab induces tumor growth inhibition through direct TweakR signaling and antibody dependent cell-mediated cytotoxicity (ADCC). Enavatuzumab can actively recruits and activates myeloid effectors to kill tumor cells. Enavatuzumab inhibits the growth of various human TweakR-positive cancer cell lines and xenografts in vitro and in vivo .

体内研究:
Enavatuzumab (10mg/kg; 腹腔注射; 每周 3 次; 6, 7 或者 9 剂) 对不同的异种移植肿瘤表现出不同的抗肿瘤活性。 Animal Model:6-week old SCID mice with SN12C or HCT116 or DLD-1 or A375 tumors
Dosage:10?mg/kg
Administration:IP; three times per week; 6 doses (DLD-1 model), 7 doses (SN12C model), 9 doses (A375 or HCT116 model)
Result:Some TweakR-expressing cells, such as SN12C and A375, were sensitive in vivo and in vitro. Some TweakR-expressing cell lines, such as HCT116 and DLD-1, were not sensitive to enavatuzumab treatment in vivo, though both cell lines were effectively killed via ADCC in vitro. Up-regulated the activation markers on splenocytes in SN12C tumor-bearing mice.

体外研究:
Enavatuzumab (0.1-1000 ng/mL; 4 小时) 在体外诱导效应细胞活化和肿瘤细胞杀伤。 Enavatuzumab (10μg/mL; 24 小时) 导致免疫效应细胞向 SN12C 和 A375 肿瘤细胞的迁移显着增加。
