Since the mid-1970’s, when Kohler and Milstein first discovered the process by which myeloma cells and splenocytes could be fused to produce monoclonal antibodies (MAbs), a whole new world of important therapeutic, prophylactic and diagnostic products has opened up, bringing in huge benefits for patients and manufacturers. The total sales of therapeutic MAbs reached more than $13 billion in 2005. Sixteen of the 18 FDA-approved MAbs came to the market after 1997, and over 150 are currently in clinical development, suggesting their increasing medical importance and the remarkable, recent advancements in development technology…

A program for control of biopharmaceutical raw materials is a critical quality system that helps assure patient safety and contributes to product quality. The systems for testing and acceptance must be scientifically based, and meet global regulatory requirements and standards. When a new raw material is sourced, it is important to quickly establish the quality profiles for the supplier and the raw material. Among the numerous challenges that confront a company attempting to establish an effective, compliant, raw materials program, this paper will address the following: • Challenges in sourcing and tracing raw materials that are suitable for use in human therapeutics • Challenges and obstacles in qualifying suppliers • Special challenges faced by a firm that has outsourced its manufacturing and/or quality control (QC) testing…
Regulations and common sense require that a manufacturer qualify both the raw materials and the suppliers the firm will use to produce GMP supplies of a pharmaceutical or biopharmaceutical. Because the firm is accepting legal liability for the quality of all raw materials, it makes good business sense to devote resources to these activities. This article explores how to assure that qualification is complete, efficient, and compliant with current good manufacturing practice (cGMP), and discusses the challenges faced by today’s manufacturers…
The modern age of blood transfusion began after the Second World War, as detailed in Douglas Starr’s book, Blood: An Epic History of Medicine and Commerce. During the war, it became apparent that early and aggressive medical treatment utilizing whole blood or plasma could increase the chances of survival for military personnel wounded in combat. In the United States, a national program to encourage blood donation was created to provide the needed blood, which was then shipped as whole blood or plasma to war zones. After the war, physicians were eager to apply surgical advances developed on and off the battlefield to the care of the general population. Because these advances relied on blood transfusion, for the public to realize their benefit, adequate supplies of whole blood and blood components needed to be available to hospitals across the country. This was often not the case…
In general, the industry has gone through another of its realignment periods, where much was learned, but a lot of restructuring and refocusing took place. Driven by the need to keep the doors open, small to medium sized firms had to do some severe belt tightening, or completely redefine themselves as to technologies, products, and personnel. Many of the larger firms reevaluated their product pipelines, and then made the changes they felt were necessary to assure future revenues, or to make themselves attractive merger partners. Numerous large mergers took place with some that were the largest the biopharmaceutical industry has ever seen. In addition, several medium-sized companies merged, or otherwise found strategic alliances that energized their product pipelines, or simply provided the cash they needed to keep going. Antibody products did very well with a number of blockbusters receiving license approval in 2003…
Within the United States, greater than 90% of the available transfusible blood products are collected, processed, and distributed by regional blood centers. The remaining blood products are collected by hospital-based blood banks and are usually provided only to patients in the collecting facility. The “region” in which a blood center offers services (i.e., collecting blood from volunteer donors and providing blood components to healthcare facilities), is usually an arbitrarily and independently defined group of contiguous counties surrounding a major metropolitan area. However, the borders of the region can be elastic and easily altered by gaining or losing access to donor groups or customers. It is not uncommon for a geographic area to be simultaneously “claimed” by neighboring competing blood centers. America’s Blood Centers (ABC) is a not-for-profit trade organization that provides services and advocacy for independent not-for-profit regional blood centers. ABC’s seventy-five members collect approximately 45% of the country’s blood products…
Long-term growth of the biopharmaceutical industry is increasingly relying on outsourcing to overcome the current capacity constraints, especially for monoclonal antibody production. Companies are often reluctant to commit to building multimillion dollar manufacturing facilities for potential products with no guarantee of approval. Therefore to offset risks, companies will enter into contract manufacturing arrangements…
Risk management deals with planning for, and reacting to, hazard or loss. The regulatory authorities are focusing on the issues associated with establishing alternative sources of raw materials, especially as they are noticing a number of related quality problems in biopharmaceutical manufacturing. Supply chain management for critical raw materials used in biopharmaceutical manufacturing is an appropriate subject for risk management. This paper analyzes five important areas in risk management as it applies to the supply chain for critical raw materials…
Growth media for mammalian cell culture are complex mixtures of raw materials that include amino acids, vitamins, inorganic salts and a wide variety of other components. The risk of infectious agent transmission, when some of these components are derived directly from animals, is a major concern in the biopharmaceutical industry, and is being actively addressed. However, the risk associated with the use of indirectly, or secondarily, derived animal components is less recognized and addressed. We have developed a classification system to define the contact level that a cell culture medium component has had with animal-derived materials. This classification system has increased the accuracy and reliability of the information we are able to obtain from raw material manufacturers, and is being used as part of a risk assessment analysis for a serum/protein-free media we are moving from development into manufacturing…
