Bispecific antibody regulations introduce new manufacturing requirements
CDMOs and drug companies making bispecific antibodies face some additional regulatory hurdles in new final guidelines issued by the US FDA.
The document – available here states that although the pathway for the evaluation of monoclonal antibodies is established, firms making antibodies that target more than one antigen needed additional guidance.
One piece of additional guidance is that the FDA may ask to compare a bispecific antibody to an approved monospecific product directed against the same antigenic target to “inform the benefit-risk assessment of the bispecific antibody.”
To date only three bispecific antibodies have been approved in the US – Janssen’s Rybrevant (Amivantamab-vmjw), Amgen’s Blincyto (blinatumomab) and Roche’s Hemlibra (emicizumab-kxwh) – although according to the FDA around 100 are in development.
