During the past 30 years, advances in medicine and pharmaceutical research generated a new class of drugs called biologics. These drugs are complex proteins, carbohydrates, or other large molecules derived from biological sources (1). By contrast with more traditional pharmaceuticals (small-molecule drugs), biologics are not synthesized chemically from less complex components, but rather are derived from or manufactured using living organisms or extracted tissue (2) Biologics make up a small but significant percentage of the overall pharmaceutical market.…

The Human Factor in Facility Design Innovation
Bioprocess and pharmaceutical production environments must be well designed to meet strict cleanroom and quality assurance (QA) standards and productivity requirements. Managers may also consider innovative ways to enhance the design of these environments to enable the people critical to their companies’ success to be more productive and effective. In today’s work culture, countless hours can be lost to poor teamwork and ineffective communication. CGMP environments present additional, unique challenges to human interaction because of their built-in process and protocol…
The Dinosaurs Reborn: Evaluating Stainless Steel and Disposables in Large-Scale Biomanufacturing
Although a number of biomanufacturers have adopted disposable technologies for small-scale process design, there has been considerable debate over the role of single-use systems in large-scale biopharmaceutical manufacturing— particularly in retrofitting facilities. Some experts have gone so far as to suggest that large-scale stainless steel fermentors are “dinosaurs,†with their large capacities, long installation lead times, and low flexibility. I advocate a systematic approach to look holistically at possible retrofit technologies in existing (stainless steel) facilities, with particular…
Single-Use Systems As Principal Components in Bioproduction
Single-use systems (SUS) have become an accepted component of animal-cell–based bioproduction. No longer a merely exciting possibility, they have emerged as a significant and growing resource for companies to use from process development to manufacturing of approved products. Having been examined for years in less regulated environments, off-the-shelf SUS are now in regular use to some extent in nearly every segment of the production train by contract manufacturing organizations (CMOs) and biopharmaceutical companies in mid-scale production applications. For…
Mixing in Small-Scale Single-Use Systems
Despite the advantages of presterile, single-use technologies, mixing is one of their most complex applications. Industry has been progressing toward using single-use bag technologies rather than traditional methods of stainless steel tanks and grades A/B processing because of the positive aspects they impart to end users, including a reduced potential for contaminants, cleaning, sterilization, and capital. These technologies offer simplicity and flexibility (1). However, using them for an operation such as mixing can add processing challenges. For example,…
Implementation of Single-Use Technology in Biopharmaceutical Manufacturing
The increasing application of single-use components and systems in bioprocessing represents one of the most significant changes in biopharmaceutical manufacturing in recent times. Driven by various factors such as improved efficiency, flexibility, and economics, this trend also presents specific challenges to end users. In one industry review by Langer, extractables and leachable compounds from disposable components were considered by end users to be a major area of potential concern regarding safety, efficacy, and stability of the pharmaceutical product…
Industrializing Stem Cell Production
Stem cells have potential as a readily available, consistent source of many differentiated cell types. This unique property can be leveraged both for therapeutic purposes and for facilitating and improving a number of drug discovery and development processes. Large-scale, “industrialized” production of human stem cells in tightly controlled conditions will be required to deliver the quantity and quality of cells needed to support clinical trials and drug discovery development activities (Figure 1). Achieving this level of production while meeting rigorous…
Increasing Biopharmaceutical Quality Through Packaging Partnerships
Containers and administration devices are integral to the safety and efficacy of biopharmaceutical therapies and must be key considerations for all new drugs coming on the market. By partnering with packaging manufacturers early in development, biopharmaceutical manufacturers can increase efficiencies in their production processes while gaining expert advice and counsel throughout a drug’s lifecycle. Such an alignment can also improve product quality, enhance regulatory compliance, and contribute to the overall state of control by preserving biopharmaceutical stability, ensuring sterilization, and…
Minimizing the Environmental Footprint of Bioprocesses
Part 1 of this two-part article introduced the need to reduce the environmental footprint of bioprocesses and evaluated the impact of solid-waste disposal. Part 2 continues by describing the effects of the remaining elements of the bioprocess footprint: wastewater, electricity, and air emissions. Wastewater Process Waste Streams: Generally, raw materials to produce and purify biopharmaceuticals fall into one of the following categories: inorganic/organic salts, sugars/polyols, trace elements, vitamins, amino acids, surface active agents, or complex (undefined)…
Formulation Effects on Opalescence of a High-Concentration MAb
Monoclonal antibodies (MAbs) are increasingly formulated at concentrations >100 mg/mL as a means to deliver a high dose in a low volume (1,2). Such high-concentration solutions are commonly opalescent (3,4), an undesirable characteristic of biopharmaceutical products for several reasons. Although it may be only aesthetic, opalescent products are not considered pharmaceutically “elegant.†Of more serious concern, opalescence may be a precursor to aggregation and indicate a propensity toward decreased product stability or quality. The term opalescent refers to…
