| Outline of Final Research Achievements |
Anti-Drug Antibodies (ADAs) are often found in patients whom therapeutic antibodies are administrated. ADAs will lead the attenuation of medical effects of therapeutic antibodies. From the standpoints of reduction in medical costs, we should develop the method to depress ADAs as early as possible. In order to depress ADAs in general, we focus on the constant region of humanized Fab, which are common in therapeutic antibodies. In this study, we prepared the humanized Fab with different conformational stability by the modification of the constant regions and examined the immunogenicities of these human Fab with different conformational stabilities.
