Despite trepidations, bioprocess oursourcing has come a long way from its inception, which was born in necessity and regulatory fear. Based on primary research that Seraphim and Pharmsource conducted in 2002, the current market for biopharmaceutical manufacturing outsourcing (upstream and downstream production of bulk APIs, but excluding separately outsourced analytics, development, and other services) was $500 to $700 million with a projection to grow to $1.5 to $2.5 billion over the next five years…

In the late research/early development stage of a biologic, it is often necessary to produce a larger quantity of a protein than a company is capable of producing internally. At this stage, the availability of the purified protein may govern its continued development. The protein needs to be produced with a minimal amount of waste; i.e., with a minimal amount of personnel and expense, in the shortest amount of time possible…

The United States Food and Drug Administration (FDA) considers antibodies and recombinant proteins as “well-characterized products.” This is based on FDA’s comfort level with reviewing multiple products over an extended period of time. This designation relates to the product, not necessarily to the system that is used to manufacture the product nor to the facility where the product is manufactured. The initial guidance document was published in 1995, prior to the use of other systems and when the majority of products were still based on mouse hybridoma technology that was 20 years old…

Among the battery of assays needed to release viral-based gene therapy biologics products, the potency assay is typically the most customized and unique of all the tests found on a Certificate of Analysis (COA). Where many safety, purity, and to some extent, identity assays can be applied with little to no custom modifications, the potency assay should be directly related to the biological activity of the construct. This aspect of the potency assay requires that development, characterization, and validation efforts be started early in the lifecycle of the product, and adequate resources should be allocated to this end. This article will cover a brief overview of available regulatory guidances, discuss hallmarks of a good cell-based potency assay, and provide a case study of an assay that was developed for a Phase 3 gene therapy product…

Only a year ago, the lack of standards for single-use equipment systems (SUS), as covered in this journal, was cited as inhibiting growth in the bioprocessing industry. The need to establish more standardized approaches for single-use devices’ design, quality, and leachables/extractables that regulators and industry end-users could accept was slowing the acceptance rate of these novel devices…

There are an estimated 225 million cases of malaria each year leading to nearly a million deaths, mostly in children under five years of age. Of the five malaria parasite species that can infect humans Plasmodium falciparum is by far the most virulent, causing 89% of all malaria related deaths in 2008. The P. falciparum parasite escapes the immune system by inserting antigens, functioning as adhesions, into the membrane of the infected erythrocyte. This allows it to sequester in the host microvasculature, thereby avoiding clearance in the spleen…
