The Future of Protein A

In this audiocast, BPI’s managing editor Maribel Rios talked with Karol Lacki (staff scientist at GE Healthcare Biosciences) about the use and future of protein A in bioprocessing. Its selectivity, robustness, and well-known ability to bind to a wide range of IgG molecules have made protein A a widely accepted affinity resin for current purification streams. Nonetheless, the industry has raised some concerns over cost, productivity, and other issues. That has led to the development of novel alternatives for purification…

Virological Safety of Biopharmaceuticals

In an audiocast with managing editor Maribel Rios, Hazel Aranha (manager of viral clearance and safety at Catalent Pharma Solutions) discusses risk assessment and management strategies since her November 2005 article, “Virological Safety of Biopharmaceuticals.” Several factors have made risk an increasingly important issue, including the globalization of the industry and concerns over emerging viruses. Some strategies for addressing risk — such as the “as low as is reasonably practicable” (ALARP) approach and conducting a cost–benefit and decision analysis —…

Anticipating Success: Meeting the Inherent Challenges of Complex Drug Substances

Realizing the full potential of a novel injectable drug compound is no small task. In the months and years that lead from the exciting discovery phase to the rigorous demands of a commercial launch, unexpected scientific and technical challenges can slow development to a halt, often at key stages. A careful, systematic approach to identifying where and why these roadblocks can occur is fundamental to staying on course. Just as important is a robust, repeatable process design focused on retaining…

Designing Quality into the Product: Early Developability Assessment in Biopharmaceutical Development

The ultimate objective in the development of any new therapeutic candidate is the validation of its mechanism of action and therapeutic efficacy in a clinical setting. Three important areas of product development critical to determining the success of a new drug candidate are: manufacturing, safety, and delivery of the product to patients. Early attrition observed during preclinical stages can often extend development timelines or require additional process optimization, therefore costing the developer more time and money. It is desirable to…

Development Strategies for Novel Vaccines for Infectious Diseases

In a vaccine development program, the probability of success at each transition decreases, even though the actual probability of moving from one phase to another can be 50–80% (Figure 1). Many compounds and vaccine candidates are screened out even before they get into preclinical studies. Developers can implement different approaches to reduce product failure risk before a program gets expensive, including Establishing a product development plan (PDP) Identifying and mitigating risk with gap analysis Learning from the mistakes of others…

Cellular Communications

Like spectroscopy, as discussed in BPI Lab last month (1), cell signaling is not a laboratory technique but rather an area of scientific study. The environment of living cells — whether prokaryotic or eukaryotic, in vitro or in vivo — comprises not only water, nutrients, waste products, and metabolites, but also molecules released by other cells in response to intracellular events such as microbial infection and disease state or environmental factors such as temperature, osmolality, and pH. Receptor proteins on…

Preparedness Ahead of Pandemic Outbreaks

Lively debate in 2012 concerned the risks and benefits of laboratory studies that created a contagious H5N1 avian pandemic influenza (flu) laboratory-strain virus. One benefit of the public debate is that it reminded governments of the increasingly likely and disastrous possibility of a devastating flu pandemic on the scale of the Spanish influenza outbreak of 1918. Natural evolution of circulating H5N1 viruses could lead to emergence of a deadly and contagious strain (1). Here we outline conventional flu vaccine options…

A CMO Perspective on Quality Challenges for Biopharmaceuticals

    The global annual revenue for biopharmaceuticals has been growing consistently since 2001, accounting for 15.6% of the total pharmaceutical market in 2011. The global biopharmaceutical market was valued at US$138 billion in 2011 and is expected to surpass $320 billion by 2020 (1). The market for recombinant proteins now exceeds $100 billion, a milestone attained in 2011. Figure 1:  ()   Much of the growth in biopharmaceutical revenue is due to an increasing number and sales of recombinant…
