TRANSFORMATIONAL SCIENCE: MOVING FROM CHALLENGES OF HIGH CONCENTRATION PROTEIN FORMULATIONS DEVELOPMENT TO MEET THE NEEDS OF HIGH POTENT BISPECIFICS
Monoclonal antibodies (mAbs) have significantly contributed in the treatment of oncological and immunological disorders over last two decades. Next advancement in this line is the introduction of bispecific antibodies – molecules which can bind to two different receptors at the same time. Engaging T-cells to target tumor cells and eventually killing tumor cells have been clinically demonstrated by such bispecific antibody. Traditionally one of the key challenge for developing mAbs is to administer high quantities of mAbs, on the other hand bispecific antibodies are extremely specific and more efficient, which makes them highly potent – leading to a reduced dose. This turns the focus from developing high concentration formulations for mAbs to the development of low concentration formulations. Scientific challenges are of very different nature with surface adsorption being the key challenge; during drug product manufacturing as well as during clinical dosing a protein molecules encounters various different surfaces and preventing/controlling adsorption on any of these surfaces is important. Analytical methods are also required to be adapted for reliable low concentration measurement for the drug product as well as the diluted preparation for infusion in clinic.
