Cell therapies are being developed for a rapidly expanding range of indications. Genzyme Corporation has a treatment of cartilage in joints in long-term follow-up stage (Genzyme Corporation, www.genzyme.com). Cell Therapies are being investigated successfully in applications to treat infectious diseases such as AIDS, repair spinal cord injuries, strengthen immune systems, and treat neurological disorders such as Alzheimer’s disease, Parkinson’s disease, and epilepsy. Positive results have been reported in treating arteriosclerosis and other cardiovascular diseases, congenital defects, breast reconstruction, and liver…

Global Vaccine Commercialization
Defining the optimal market entry strategy for a vaccine is challenging. Worldwide, vaccine markets are commoditized andvery heterogeneous. In addition, with growth and evolving technology, the business model in the vaccines sector is changing. From the traditional vaccine model, constituted mainly of pediatric vaccines used to prevent a well-known series of viral and bacterial infections in large cohorts of healthy patients, we are seeing the emergence of a more pharma-like model that has been stimulated by new technologies, innovation, and…
Optimizing Vaccine Supply Chains Through Quality Management in Manufacturing
The recent product recalls of PedvaxHib and Comvax vaccine batches are a reminder that the control of vaccine manufacturing processes is of the highest importance. This rings especially true because the target population for these two products is children under the age of five. The Hib vaccine guards against meningitis and other serious infections caused by the bacterium Haemophilus influenzae. In this particular recall, type b vaccine was tested and determined to be free of contaminating microorganisms before being released…
The Emerging Generation of Chromatography Tools for Virus Purification
Chromatography media and methods have evolved continuously since their introduction a half century ago. Traditional methods use columns packed with porous particles. They still dominate chromatography applications in the field of virus purification, but the past 20 years have witnessed the ascendance of alternative supports, namely membranes and monoliths. These newer media exploit the familiar surface chemistries — ion exchange, hydrophobic interaction, and affinity — but they use unique architectures that offer compelling performance features. The Architecture of Chromatography Media…
The Next Generation of Biologicals and Their Production Systems
Combined advances in molecular biology, cell biology, and genomics have led to a wealth of new information about cellular processes. A growing understanding of the fundamentals of cell biology is now being translated into products that use an approach to exert a biological effect that is different from that of most biologicals currently on the market. To date, most biological products consist of highly purified proteins with a specific activity that alleviates or stops the symptoms of a certain condition.…
