Profitability in the Biosimilars Market

The biosimilars space offers significant commercial opportunity. About US$60 billion of branded biologic sales will lose patent protection over the next few years, including some of the largest-selling monoclonal antibodies (MAbs). Companies are jostling among themselves, each seeking the best position to exploit that opportunity. Regulators are creating and refining the necessary pathways to success, alliances are being forged, and companies are being acquired. Despite the significant opportunity for biosimilar MAbs, significant risks remain. Perhaps the most significant of those…

Drug Products for Biological Medicines

The California Separation Science Society (CASSS) held a Chemistry, Manufacturing, and Controls (CMC) Strategy Forum on drug products for biological medicines in July 2012 in Bethesda, MD. Topics included novel delivery devices, challenging formulations, and combination products. This CMC Strategy Forum aimed to promote an understanding of how best to increase the speed and effectiveness of drug product and device development for both large and small companies. Participants focused on areas that improve the likelihood for regulatory success, reduce risk,…

A Salt-Tolerant Anion-Exchange Chromatography Sorbent for Flexible Process Development

In most downstream purification processes designed for biopharmaceutical drug production, dilution and diafiltration sequences are unavoidable. Such operations are routinely used to adjust a feedstock or chromatographic fraction to the optimal conditions required for best process performances. Nevertheless, those steps are often time, water, and labor consuming without participating directly in final product purification. Because biopharmaceutical production is increasingly driven by cost reduction, a possible means for enhancing process economics is to streamline purification by eliminating these unit operations before…

Concerns, Collaboration, and Capacity

The BPI Theater is a 50-seat venue that for seven years has been located at the heart of the BioProcess Zone on the exhibition floor of the BIO International Convention. There, BPI provides attendees with four days of live presentations focusing on the latest scientific advances and business trends in biotherapeutic development and manufacturing. On Monday afternoon, 22 April 2013, Patricia Seymour of BioProcess Technology Consultants (BPTC) moderated a roundtable discussion on biosimilar development in the BPI Theater at BIO…

Overview of a Scale-Up of a Cell-Based Influenza Virus Production Process

The aim of this white paper is to demonstrate how GE Healthcare Life Sciences single-use products can be applied in the field of vaccine manufacturing. A brief discussion around modern vaccine processes is followed by a case study showing the scale-up of upstream and downstream processes for the production of a cell based live attenuated influenza virus using single-use ReadyToProcess technology. Single-use equipment enables quick changeover between products, minimizes risk for cross-contamination between batches, and reduces the need for cleaning and validation operations.

Broadening the Baseline

When the editors of BPI asked us at BPSA to put together a content-rich article on single-use issues, we were happy to do so. Our challenge was how to bring in multiple viewpoints about the growing business of single-use that would be a “quick read” for the BPI audience. The answer: an expert colloquy. Represented here are several of the most qualified industry spokespersons in single-use — all are members of BPSA and speak as directors of the alliance. Their…

Better Cells for Better Health

Since its inception 35 years ago, the biennial meeting of the European Society for Animal Cell Technology (ESACT) has built on a tradition of combining basic science and applications into industrial biotechnology to become the international reference event in its subject matter. Every other year, this gathering of academics and industry professionals features a famously exciting social program and an extensive vendor/supplier exhibition specific to animal cell technology. ESACT meetings are much-anticipated international venues for information exchange, inspiration, networking, and…

High-Throughput Chromatography Screenings for Modulating Charge-Related Isoform Patterns

Monoclonal antibodies (MAbs) are an important class of biopharmaceuticals and are widely used to treat a variety of diseases such as cardiovascular diseases, cancer, and blood disorders. Antibodies are very complex proteins that show a high degree of microheterogeneities, including charge-, hydrophobicity- and size-related variances (1). Such variants can arise during any stage in a manufacturing process or storage as a result of enzymatic or nonenzymatic processes (2). Particular antibody variants that may affect the in vitro and in vivo…

Advances in Sensor Technology Improve Biopharmaceutical Development

Today’s biomanufacturing operations require constant management of biopharmaceutical process attributes throughout process development and production. Continuous online measurements of pH, dissolved oxygen (DO), oxidation–reduction potential (ORP), and conductivity (Figure 1) allow real-time industrial process monitoring and adjustment. These functions are crucial to process improvement studies and accurate, reliable manufacturing of high-quality products. Figure 1: () “In the pharmaceutical industry, it is extremely valuable to see how an attribute changes with time and correlate that change with parts of the process,”…

Single-Use Technology and Modular Construction

To enable broad, global access to life-saving biopharmaceutical products, our industry is facing significant pressure to reduce the overall cost of manufacturing and enable local manufacturing where possible. Combined with growing markets outside the United States and Europe and development of high-titer, high-yield processes, that pressure has led to a shift in the industry’s approach to facility design and construction. Today’s biopharmaceutical production facilities must be flexible, cost effective, and readily constructed with minimal capital investment and construction timelines. As…
