Changes in Raw Material Sources from Suppliers

    Maintaining the supply chain of single-source raw materials is of utmost importance for a biopharmaceutical company’s manufacturing operations. As often happens, a supplier will notify its customer of process changes that might affect the quality or properties of supplied materials. Occasionally, a supplier might notify the customer of substitutions in its own supply chain or other changes in the source of its own raw materials. Customers must conduct appropriate testing using the “new” raw material(s) to ensure acceptable…

Polymers and Additives Used in Fabrication of Disposable Bioprocess Equipment

The materials used to fabricate single-use processing equipment for biopharmaceutical manufacturing are usually polymers, such as plastic or elastomers (rubber), rather than the traditional metal or glass. Polymers offer more versatility because they are light-weight, flexible, and much more durable than their traditional counterparts. Plastic and rubber are also disposable, so issues associated with cleaning and its validation can be avoided. Additives can also be incorporated into polymers to give them clarity rivaling that of glass or to add color…

How Pore and Fibrous Interstice Structure Influence Filter Performance

    A common objective in pharmaceutical processing is the removal of solids from fluid suspensions through filtration. The usual purpose is the removal of the solid particles to a specified extent, within a given time interval, at the largest possible throughput. Attainment of those goals is managed by proper selection of filtration conditions: principally an adequate effective filtration area (EFA) as defined by filter porosity and a proper rate of flow as regulated by applied differential pressure (ΔP) over…

Effect of Sterilization on the Mechanical Properties of Silicone Rubbers

    Silicone rubber is widely used in the pharmaceutical industry, where sterilizability is an essential requirement for all fluid transfer equipment. Pharmaceutical products are sterilized frequently and repeatedly by high-level energy and/or chemical vapor to eliminate bacterial surface contamination. Such treatments may also affect the molecular structure of silicone rubbers, causing changes in their physical properties and performance. Several studies on this topic have been reported; until now, however, no systematic investigation has been performed on the effect of…

Process Development’s Impact on Cost of Goods Manufactured (COGM)

    Manufacturing throughput (the amount of material a plant can produce per year) is affected by process yield and plant run rate. The higher they are, the more a plant can produce per year, requiring fewer lots to meet annual demand. Although a process development team obviously determines the process yield, the team also determines the impact on the run rate of duration and potential implementation complexity of the entire train of unit operations. Thus, an optimized process maximizes…

TIDES® Oligonucleotide and Peptide Technology and Product Development

Moving to Boston, MA, after four years in the western United States (Las Vegas and Carlsbad, CA), the Tides conference continues to be the must-attend event for the industry that grows in attendance each year. The 2010 agenda includes thought-provoking keynotes and featured presentations, a compelling regulatory session, and discussions with CBER, FDA, and European regulatory agency speakers. In separate tracks for each type of molecule, learn more from the new, full-day sessions on CMC manufacturing and analysis and a…

Making a Positive Urban Impact

Like so many other midwestern industrial cities, St. Louis, MO, saw its manufacturing base decline over the past 40 years. Led by the automobile, shoe manufacturing, and defense industries, that decline was coupled with a notable decrease in the city population. From 1950’s high of 850,000 people, the city dwindled to ~350,000 by the 1990s, although its metropolitan area grew to >2,000,000. Accelerating growth of high technology in the 1990s had minimal impact on St. Louis the “old industry” the…

The Growing Role of Biobanking in Today’s Medical Environment

    For decades, biomaterials such as tissues, blood, and serum derived from clinical testing have played a critical role in drug development and academic research. The recent focus on molecular-based therapies, genomics, and biomarker discovery in today’s medical research have dramatically transformed the way biotechnology and pharmaceutical organizations collect, transport, and store their biospecimens. As the pharmaceutical industry shifts toward a more personalized approach to medicine, the need for high-quality, well-maintained biospecimens is at the forefront of medical research.…

Managing the Product Pipeline

    In 2007, the biopharmaceutical market represented ~$71 billion: 10% of the entire pharmaceutical market. Therapeutic proteins and monoclonal antibodies (MAbs) account for 98% of all biotherapeutics in development, the rest being blood proteins and enzymes — all the products of recombinant DNA technology. Before the recession hit full on, growth of this market was estimated by some at ~15%. (Now it’s hard to predict at all.) Making biotech drugs consumes huge amounts of time and money, but they…
