Current perspectives on biosimilars.

In this work, an overview of the biosimilars market, pipeline and industry targets is discussed. Biosimilars typically have a shorter timeline for approval (8 years) compared to 12 years for innovator drugs and the development cost can be 10-20% of the innovator drug. The biosimilar pipeline is reviewed as well as the quality management system (QMS) that is needed to generate traceable, trackable data sets. One difference between developing a biosimilar compared to an originator is that a broader analytical foundation is required for biosimilars and advances made in developing analytical similarity to characterize these products are discussed. An example is presented on the decisions and considerations explored in the development of a biosimilar and includes identification of the best process parameters and methods based on cost, time, and titer. Finally factors to consider in the manufacture of a biosimilar and approaches used to achieve the target-directed development of a biosimilar are discussed.

The therapeutic monoclonal antibody market.

Since the commercialization of the first therapeutic monoclonal antibody product in 1986, this class of biopharmaceutical products has grown significantly so that, as of November 10, 2014, forty-seven monoclonal antibody products have been approved in the US or Europe for the treatment of a variety of diseases, and many of these products have also been approved for other global markets. At the current approval rate of ∼ four new products per year, ∼ 70 monoclonal antibody products will be on the market by 2020, and combined world-wide sales will be nearly $125 billion.

Mammalian cell culture capacity for biopharmaceutical manufacturing.

: With worldwide sales of biopharmaceuticals increasing each year and continuing growth on the horizon, the manufacture of mammalian biopharmaceuticals has become a major global enterprise. We describe the current and future industry wide supply of manufacturing capacity with regard to capacity type, distribution, and geographic location. Bioreactor capacity and the use of single-use products for biomanufacturing are also profiled. An analysis of the use of this capacity is performed, including a discussion of current trends that will influence capacity growth, availability, and utilization in the coming years.
