The multi-attribute method (MAM) is an analytical method using high-resolution LC-MS to quantify post-transrational modifications (PTMs) of therapeutic antibodies. The concept of MAM was recently proposed and research in MAM has been conducted globally, especially the US and European countries. On the other hand, a progress in this research field in Japan has been behind those countries. In 2021, the National Institute for Materials Science (NIMS) and 7 Japanese pharmaceutical companies established a joint research group for MAM in “Materials open platform (MOP) for pharmaceutical science” of NIMS (Platform director: Kohsaku Kawakami, NIMS), which is a framework designed to facilitate joint research by competing companies within the same industry. In this joint research, a comparative study was conducted among attending companies using NIST-mAb to evaluate company-to-company variations in measured values of PTMs. In this study, we obtained some findings for reducing the variations. In this presentation, we will introduce an overview of this joint research and the current progress.
