Future Manufacturing Strategies for Biosimilars

Biosimilars are a relatively new subset of biopharmaceuticals, with the biotechnology industry finally maturing such that off-patent generic-type products increasingly will be entering major markets (1–3). So far, more than 20 biosimilars for a limited number of reference products have been approved in major markets, primarily the European Union. Only two products have been formally approved as biosimilars in the United States. For this rapidly growing industry sector, little consensus or authoritative information is available yet regarding how and where…

Outsourcing Biosimilars Development

A rapid increase in the number of companies working on development and registration of biosimilars has created a significant market for contract testing and manufacturing organizations (CTOs and CMOs) providing outsourced services specific to these products. Biosimilar developers turn to contract organizations when they lack either the internal capability or capacity for conducting certain work as well as when they require additional resources to bring products to market rapidly. A wide range of contract services are available, and each particular…

Critical Factors for Fill–Finish Manufacturing of Biologics

Over recent decades, protein-based therapeutics have emerged as key drivers of growth in the pharmaceutical industry. Drug development pipelines have filled with biologics, and a handful of monoclonal antibody (MAb) products have become some of the best-selling drugs around the world. Production of biotherapeutics is often challenging because of the inherent instability of these large, complex molecules. Their fragile nature has forced manufacturers to change how bulk drug substances (BDSs) are handled and final drug product is formulated, sterile filtered,…

Special Report on Continuous Bioprocessing: Upstream, Downstream, Ready for Prime Time?

Once an engineering curiosity and smallscale laboratory technique, continuous bioprocessing has evolved in just a few short years to a topic of intense and increasing interest to most bioprocessors. Critics point to a steep learning/adoption curve, but that is nothing new in biomanufacturing.Andrew Zydney is a distinguished professor of chemical engineering at Pennsylvania State University. He has noted these challenges facing continuous processing: commercially unproven unit operations (especially downstream), a lack of equipment robustness, sterility concerns, and uncertain development timelines…

Validation of Controlled Freezing and Thawing Rates: A 16-L–Bag Study

It is well understood that freeze– thaw processes affect the product quality of biopharmaceuticals (1–3). It has been reported that there is no consistent method of controlled freezing and thawing rates for biological formulations (4). Traditionally, ultralow temperature storage chambers that were not designed for freezing have been used to provide an energy state for the environment surrounding the product with very little excess capacity to change the state of the product. This study details a consistent method for controlled-rate…

Factories of the Future: Can Patient-Specific Cell Therapies Get There from Here?

In many ways, patient-specific cell therapies (PSCTs) are still the “new kid on the block” in medicine. Researchers, therapeutic developers, manufacturers, regulators, and payers are still exploring and developing an understanding of the powerful benefits and unique challenges associated with this growing industry. As we all become more familiar with PSCTs, an evolution will need to occur — as it has for automobiles, computers, and every technological advance in human history — for these therapies to become widely adopted, cost-efficient,…

Emerging Platform Bioprocesses for Viral Vectors and Gene Therapies

Recent advances in molecular biology are expediting genomic sequencing to underpin precision medicine. Such progress is positioning gene and gene-modified cell therapy on the cusp of an extraordinary revolution in patient care for presently unmet medical needs — and a new therapeutic class that could rival monoclonal antibodies (MAbs) in importance. However, despite substantial strides made in clinical trials, the bioprocessing community is struggling to fulfill growing demands for biomanufacturing capacity to make gene and gene-modified cell therapies — including…

Cancer Immunotherapies: Fulfilling the Promise of Protein and Cell Therapies

With few exceptions, both small-molecule and biological cancer treatments have contributed only incrementally towards achieving long-term responses or outright cures. In this regard, emerging cell- and protein-based cancer immunotherapies represent game-changing strategies for treating even refractory cancer. With long-term responses now possible, medical science may be on the verge of delivering on the long-unfulfilled promise of making cancer a manageable disease. But impediments to commercializing cancer immunotherapies are substantial. Producing cell-based treatments entails substantial hands-on manipulation and perfecting the logistics…

Automation of CAR-T Cell Adoptive Immunotherapy Bioprocessing: Technology Opportunities to Debottleneck Manufacturing

Continued clinical efficacy demonstrations of cell-based immunotherapies (iTx) such as chimeric antigen receptor T cell (CAR-T) therapies has made the prospect increasingly likely of an immunotherapy product achieving conditional market authorization in the short term. For example, Novartis and the University of Pennsylvania’s lead candidate (CTL019) for treating a range of hematological malignancies received breakthrough status from the US Food and Drug Administration (FDA) in 2014, permitting access to an expedited drug development pathway for high unmet medical needs (1).…

Development of a Novel Cell-Separation Platform: Discussion with Quad Technologies CEO Sean Kevlahan

Releasing and separating cells from surfaces and capture molecules are critical steps in cell therapy development. Research into such therapies as chimeric antigen receptor T cells (CAR-T) cancer therapies and stem-cell regenerative medicines demand the isolation and purification of viable and functional target cells. A number of cell-separation strategies can be used to produce such cells, but they are not able to deliver the required efficiency or scalability and can also cause damage to cells or affect their phenotype. Since…
