New analytical approaches, next-generation therapies, and innovative strategies for culture systems using a range of bioreactor types have led to a better understanding of upstream processes while reducing biopharmaceutical process/development time and costs.
Smart(er) Facilities: Automation and Innovation Can Take Bioprocessing to the Next Level of Intelligence
Today’s biomanufacturers need to be able to add capacity and capability quickly; provide increased supply service to customers on demand; and streamline the flows of personnel, traffic, utilities, and materials throughout bioprocess facilities. Companies need to be flexible enough to subtract capacity and retool quickly to produce new or different products. Future facilities are likely to be automated to some extent and use robotics in manufacturing. With personalized medicine on the rise, bioprocessors can benefit from colocation with academic research centers, laboratories, and clinics. Biofacilities should be designed to affect the environment as minimally as possible. And they would do well to be built with employees’ comfort in mind and serve as good neighbors in their local communities. It all comes down to a “smarter” approach. This featured report begins with a staff-written review, then includes end-user perspectives and supplier insights.
Cell Therapies: Technologies and Analyses to Advance Manufacturing
With several products in late-stage development, regenerative medicine is going mainstream. Even as some regulatory and manufacturing challenges are met, others arise.

Continuous Processes: Disposables Integrate
Upstream and Downstream Processing
Perhaps the “hottest” buzzwords in biomanufacturing today are continuous processing and single-use technologies. They are closely related — as one is increasingly enabled by the other. Perfusion and other approaches have begun to blur the line between upstream and downstream processing (by performing certain separation/clarification duties as part of their function). And separations technology suppliers are offering solutions to the challenge of continuous drug-substance purification. Alongside a review of these advancements by BPI’s senior technical editor, contributed articles expand on continuous upstream/production methods and continuous downstream processing technologies.
Biosimilars: Tackling the
Technical and Regulatory Challenges
Biosimilar products have come about as a way to make biopharmaceuticals that are otherwise too costly available to a broader market. Like generic small-molecule drugs, they build on the success of licensed products. And although regulatory pathways allow biosimilar developers to bypass certain expensive testing, they are not generic drugs. Technical challenges remain a part of their development. This Featured Report contains an overview of those challenges and articles that dive into technologies that can help, regulatory hurdles that remain, and a look at the countries that are leading the way globally.
