Panitumumab is a fully human monoclonal antibody with extremely high affinity (KD ≈10-11 M) to the epidermal growth factor receptor (EGFR) and could mediate potent blockade to EGFR/EGF engagement. In conclusion, the pharmacological and safety profiles of BB-1705 were well established through in vitro potency testing, in vivo efficacy study and general toxicity studies. This data support BB-1705 as a potent antitumor agent to EGFR medium to high-expressing cancers and warrant further investigation of BB-1705 in human clinic trials.
