Manufacturing Systems, Single-Use

The adoption of single-use containers in the biopharmaceutical industry is becoming more frequent as the popularity and availability of the technologies increase. The choice of a solution for storage in single-use containers clearly depends on the application and the inherent risks associated with the application. A "one fits all" single-use system cannot respond to all the requirements of a particular step in a biopharmaceutical process, much less to all the steps of a process. The needs of an application will lead to very specific single-use solutions.

The deliberate reuse of disposables has caused many clinically significant problems.

In its early days, the biotech industry was almost entirely science driven, but it has since expanded from a laboratory environment to a sophisticated and dynamic manufacturing environment. As technological discoveries are increasingly translated into commercial products, biotech companies are realizing that they must generate a stronger return on assets.

Filtration systems exemplify disposable technologies that can be presterilized.

The number of biotechnology-based human therapeutic products in the late-stage pipeline, and the average cost to commercialize a biotech product, have steadily increased. This has required biotech companies to use economic analysis as a tool during process development and for making decisions about process design. Process development efforts now aim to create processes that are economical, as well as optimal and robust.

Disposables require less space than conventional equipment, and they can be assembled offsite into complete process trains.

Disposables can be used for media preparation, clarification, filling in downstream processes . . .

The cell density achieved in a CELLine bioreactor is typically 1 to 2 orders of magnitude higher than in a conventional culture vessel

Cell-line and process development expertise, along with disposable systems, assist in implementing strategies for fast expression enhancements.

Disposable technology has been used effectively as a process solution for over 25 years and new uses and applications are constantly being developed. The key to all applications is the ability to pre-sterilize components and systems with gamma radiation and package them against contamination.

Disposable products and systems have come a long way since they first entered the small-lab market in the 1970s. Today they are available for practically every aspect of biopharmaceutical manufacturing. Disposable systems are used for filtration, clarification, purification, and separation applications used in the production of vaccines, monoclonal antibodies, and other therapies. As the use of disposable systems grows, the concept of a completely disposable manufacturing process is becoming a reality.

Using disposable components for bioprocessing can reduce costs and complexity and may play an increasing role in large-scale biopharmaceutical manufacturing.

The biotechnology and pharmaceutical industries have some overriding concerns, namely regulatory and compliance issues, insufficient manufacturing capacity, and the economic challenges of producing niche drugs and therapies.

Biopharmaceutical manufacturers face many bioprocessing concerns including safety, flexibility, maintenance, capacity, capital investment, and process costs. Disposable products can reduce some of the burden.
