The requirement for visual inspection of pharmaceuticals has been a compendial expectation for over a century, with some advancement of visible particle control strategies in recent years. Current philosophies include a 100% inspection and an Accepta

Industry experience suggests that g-forces sustained when vials containing protein formulations are accidentally dropped can cause aggregation and particle formation. To study this phenomenon, a shock tower was used to apply controlled g-forces to gl

Tungsten microparticles may be introduced into some pre-filled syringes during the creation of the needle hole. In turn, these microcontaminants may interact with protein therapeutics to produce visible particles. We found that soluble tungsten polya

Quality by Design for Biopharmaceutical Drug Product Development ISBN: 9781493923151
Quality by Design (QbD) of biopharmaceuticals assumes that desired properties of the final drug product can be predicted with the help of various analytical and characterization methods during the development process. This should be translated into a

Particles isolated from a pre-filled syringe containing a protein-based solution were identified as aggregated protein and tungsten. The origin of the tungsten was traced to the tungsten pins used in the supplier's syringe barrel forming process. A t

Stainless steel is a ubiquitous surface in therapeutic protein production equipment and is also present as the needle in some pre-filled syringe biopharmaceutical products. Stainless steel microparticles can cause of aggregation of a monoclonal antib

Therapeutic proteins are exposed to various wetted surfaces that could shed subvisible particles. In this work we measured the adsorption of a monoclonal antibody (mAb) to various microparticles, characterized the adsorbed mAb secondary structure, an

Tungsten has been associated with protein aggregation in prefilled syringes (PFSs). This study probed the relationship between PFSs, tungsten, visible particles, and protein aggregates. Experiments were carried out spiking solutions of two different
