In Vivo Efficacy Study with Target Positive Xenograft Model

Tumor Volume Changes in SCID Mice Bearing NCI-N87 Xenografts

In-house prepared Trastuzumab-DM1 was tested in comparison with trastuzumab (Herceptin) in an in vivo study using gastric tumor cell Line NCI-N87 xenograft model of NOD-SCID mice.    The tumor growth curves demonstrate tumor growth inhibition and complete regression after 3 doses i.v. of T-DM1 (3mg/kg and 15 mg/kg) compared to insignificant efficacy of naked antibody (n = 10 per group).
