Rational design to biologics development: The polysorbates point of view

Brovč, Ema Valentina, Mravljak, Janez, Pajk, Stane and Sink, Roman (2020) Rational design to biologics development: The polysorbates point of view. International Journal of Pharmaceutics, 581. ISSN 18733476


Formulation development is an essential part of any biopharmaceuticals development programme, and this will affect quality, safety and efficacy of the final drug product. The vast majority of biopharmaceuticals on the market are therapeutic proteins; however, these are less stable compared to conventional pharmaceuticals. To counter aggregation, denaturation and surface adsorption of proteins in solution, surfactants are added to the formulations; however, the choice of the best formulation is a challenge that is faced during formulation development. Polysorbates are the most widely used surfactants in the pharmaceutical industry and are presented in >80% of commercial monoclonal antibody formulations. In this review, we provide a general overview of polysorbates and their issues, and the characteristics that have to be taken into account during formulation development. Degradation of polysorbates, namely by hydrolysis and/or oxidation, is one of the main concerns associated with their use. Furthermore, degradation of polysorbates is determined by formulation composition, pH and storage conditions, therefore underlining the importance and complexity of protein formulation development using polysorbates. A need-based approach should be used for correct selection of excipients in protein formulations that contain polysorbates.
