The 2017 BPI Theater @ BIO took place June 20-22 in San Diego CA and focused on two main themes: emerging therapies and emerging technologies. The BPI Theater provides convention attendees working and interested in biopharmaceutical research, development and manufacturing with a dedicated destination to meet, network, and experience the latest science and technology trends impacting bioprocessing. Summaries of the presentations were included in the July-August Featured Report, and full video presentations are available for on-demand viewing.

Particulate Contamination in Single-Use Systems: Challenges of Detection, Measurement, and Continuous Improvement

Patients receiving particulate contamination through parenteral delivery of biopharmaceuticals presents a significant potential health risk. However, the severity of that risk often is unclear. It depends on the route of administration, dosage volume administered, particle properties and amount received, and the ultimate fate of particles within a patient’s body (1). The appearance of particulate contamination also can be a visible indicator of product quality. Consequently, when such contamination is discovered within biopharmaceutical manufacturing operations, often it triggers costly investigations and…


Regulation, Analytical, and Process Issues with Leachables: Toward Harmonization for Latin America with Europe and North America

The pharmaceutical industry follows strict regulations regarding impurities, including process-related leachates. Plastic manufacturers use hydrophobic, nontoxic additives for manufacturing containers for use in the pharmaceutical and food industries. However, some issues about dealing with such impurities are not yet resolved. In developing countries, regulators are working on guidelines to help local companies ensure characterization of impurities. In this exclusive editorial eBook, authors from Mexico describe some issues related to plastic leachables in the context of ongoing efforts to harmonize regulations…


Difficult-to-Express Proteins: Resolving Bioprocessing Challenges with a Scalable Perfusion Bioreactor

Recent advances in protein engineering have identified new classes of complex biotherapeutics that challenge existing manufacturing platforms. These products have unique cell culture requirements that make them difficult to manufacture cost effectively. Industry standard bioprocessing platforms include large-scale (1,000–5,000 L) batch and fed-batch stirred-tank bioreactors. Historically, the powerhouse molecule of the biologics industry has been human IgG, which necessitates those large-scale platforms. Difficult-to-express proteins and other new modalities (including precision medicine and orphan drugs) have increased pressure on manufacturers to…
