The biopharmaceutical industry is emerging from four years of economic challenge in a very healthy state. Process improvements over the past decade have played a major role in keeping the industry healthy. Earlier this decade, most companies were more concerned about quickly getting their drug products to market than about strategically controlling costs of operations. But according to my group’s recent study, this has changed in most areas of manufacturing. In fact, although this year companies reported overall…
Manufacturing
A Decade of Outsourcing
Outsourcing has been such an integral part of the bioprocessing industry that BPI made it the focus of its first supplement (September 2003). Since then, manufacturers continue to reach beyond local and national borders to extend their networks of partnerships to emerging markets. Global economics during the past decade have not always made outsourcing easy. Ten years ago, manufacturers faced tough decisions over whether it was more cost effective to outsource or keep process activities in-house (possibly expand…
Outlooks on Standardization
The Friday workshop of the 2011 BPI Conference in November may have been titled “Industrialization of Single-Use Manufacturing Technologies,†but in the discussion afterward, the mainly end-user audience zeroed in on an on-going debate in single-use implementation: standardization. Comments and questions echoed the current opinions, most of which were well known to the all-supplier panel and others present. To follow up on this discussion, I spoke with members of that panel because — as one expert put it…
The Maturation of Single-Use Applications
“Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning.†—Albert Einstein Single-use systems (SUSs) have been treated as novel technologies for some time. I have spent much of the past 10 years introducing clients to SUSs and integrating them into conventional processes. They are part of the biopharmaceutical development and production landscape and a mature, integrated option for bioprocessing. The value of SUS integration is soundly substantiated: reduced cross-contamination risk…
Single-Use Technology Supports Follow-On Biologics
Follow-on biologics (FOBs, or biosimilars) differ from generic small-molecule compounds and pioneer biopharmaceuticals in several ways. Those differences affect aspects of their regulatory approval pathway, analytics, and marketing (1). Many biological active pharmaceutical ingredients (APIs) are actually incompletely characterized dynamic mixtures of macromolecules with slightly different primary compositions or higher-order structure (microheterogeneity). Those properties of macromolecules (unlike small molecules) are greatly influenced by their individual manufacturing process. Emerging regulatory guidelines for follow-on biologics are clarifying aspects of their…
Implementing Custom Single-Use Solutions for Cell Therapy Production
Cellular therapy continues to expand and gain momentum, as evidenced by the growing number of companies and clinical trials in the field each year. Early potential therapies were developed solely by investigators without communication or input from manufacturing experts. That communication gap led to numerous setbacks as potential products were developed without roadmaps for feasible manufacturing scale-up (or scale-out). Contributions from members of the cell therapy community over the past few years have significantly improved the situation in the form…
Fight Cancer with Nanotechnology
Imagine a diagnostic test that sifts through millions of molecules in one drop of a patient’s blood to detect the tell-tale protein signature of a cancer subtype. Envision a drug “ferry†that doesn’t release its cytotoxic contents until it slips inside cancer cells — or a molecule or small panel of proteins that can reveal within days whether a cancer treatment is working. Bioprocess Applications of Nanoparticles () Researchers have created nanosized particles and devices that are…
Large-Scale, Insect-Cell–Based Vaccine Development
Vaccines are among biotechnological products characterized by continuous growth over the past decade. According to a 2011 report, the global vaccine market is expected to reach US$34 billion in sales by 2013 (1). Much development can be ascribed to vaccine treatments for cancer, autoimmune, and infectious diseases (which have risen significantly) as well as the growing worldwide population and emergence of new pandemics. Although to date the main health impact of vaccines is still in disease prevention, the…
Approaches to Debottlenecking and Process Optimization
Two major challenges associated with optimizing biomanufacturing operations remain unresolved. The first is variability: how to understand and improve manufacturing with significant variation in process times throughout all unit operations. The second is complexity: modern biomanufacturing facilities are complex and interconnected, with piping segments, transfer panels, and valve arrays, as well as water for injection (WFI) and other shared resource constraints. That complexity is becoming even greater with the need for process standardization and processing of higher (and…
Scaling Up Stem Cells
Cell-based products are becoming increasingly important as potential biotherapies. Cell therapy is predicted to have a huge impact on the healthcare sector over the coming decades. Stem cells, in particular, are investigated as potential treatments for a diverse range of applications (such as heart disease and metabolic and inflammatory disorders) in which they might be used to restore lost biological functions. The cell therapy industry is starting to mature. Several emerging companies are now supporting late-stage clinical trials,…
