Implementation of postlicensure process improvements in the biopharmaceutical industry can benefit patients and drug manufacturers alike. Here we demonstrate through a case study how a change to the cell culture medium and process can be taken from proof of concept through scale-up to demonstration of feasibility. We further illustrate the scope and complexity of implementing a change in commercial manufacturing to realize significant benefits such as increased production capacity over an existing legacy process. The Importance of Postapproval Improvements Drug…

Impact of Process Interruption on Virus Retention of Small-Virus Filters
Manufacturers of biopharmaceuticals using mammalian cell culture must have processes in place to minimize the likelihood of virus contamination of their products. Regulatory agencies provide guidelines for testing strategies and best practices to assure raw-material safety and control of the manufacturing process. Safety assurance relies on an interdependent matrix of managed risks, including characterization and control of raw materials, extensive testing of process intermediates, and demonstration of the virus removal capabilities of purification unit operations Figure 1: () A dedicated…
Government Medicaid Reporting
On 27 January 2012, the US Centers for Medicare and Medicaid Services (CMS) published a much-anticipated proposed average manufacturer price (AMP) rule for implementing related prescription drug provisions of the Patient Protection and Affordable Care Act (PPACA). The new rule will create serious financial, administrative, and operational challenges for the life-sciences industry. Nearly two years later, the final rule has not been issued. Without official direction, we can look back at the proposed rule’s purpose and recommendations for manufacturers based…
Biologics Have a Robust Pipeline
Earlier this year, the Pharmaceutical Research and Manufacturers of America (PhRMA) released a report titled 2013 Report: Medicines in Development – Biologics. It lists 907 biologics currently in development at “America’s biopharmaceutical research companies.” The list includes biologics targeting more than 100 diseases that either are currently in human clinical trials or are under review by the US Food and Drug Administration (FDA). Of those 907 product candidates, the most common types are monoclonal antibodies (MAbs, 338), vaccines (250), and…
The Role of Medical Affairs in Moving from R&D to Commercialization
Bringing a new pharmaceutical product to market is a unique process based on a number of requirements for supporting a product launch. For a research and development (R&D) company, launching a product into market may seem to be an issue for someone else to handle in the far-distant future and at a much later time. But even at laboratory or early development stages, biotechnology companies should understand the language of pharmaceutical companies and know how that industry operates. Doing so…
Tunable Half-Life Technology
While a constantly developing market puts increasing pressure on pharmaceutical companies to provide advanced and personalized therapies, the industry is investing heavily in the development of targeted biologics. The aim is often to take new therapeutics through clinical trials and to market as quickly as possible and to develop more novel, tailored drugs. One common challenge for many biologics is their short plasma half-life. That often leads to reduced bioavailability, meaning that an administered drug will clear from a patient’s…
Manufacturing Culture
Life sciences company leaders need to put the right people, processes, and technologies in place to create evolutionary cultures. Such cultures would embrace advanced manufacturing process intelligence and reap related business benefits. Since the late 1990s, my software company has helped biomanufacturers improve their process understanding. In that time, we’ve seen regulatory drivers such as quality by design (QbD) and process analytical technology (PAT) guidances call for improved manufacturing process performance through better process understanding and optimization. We define process…
Rapid Pharmaceutical Product Development
A Chemistry, Manufacturing, and Controls (CMC) Strategy Forum was held in January 2012 in San Francisco, CA, to examine the topic of rapid pharmaceutical product development. The purpose of this meeting was to promote an understanding of how best to increase the speed of product development, focusing on areas that improve chances of regulatory success while lessening the time it takes to get a product through development and onto the market. Participants also sought to identify and discuss…
A Framework for Process Knowledge Management
Process development and manufacturing for biopharmaceuticals are often disjointed activities. Disconnects between groups within an organization can be aggravated by a lack of common terminology and poor data-management practices. Implementing a simple data model based on the ISA-88 standard for batch control can help companies capture process and facility data throughout their product life cycle (1). The first half of this two-part article illustrates how translating a process description to a structured electronic format could transform the bioprocessing…
Encouraging In-House Disclosures In a Whistleblower’s World
Compliance officials have a great deal to worry about. They are judged by results and loaded with stress over the latest changes in government guidance documents and internal budget pressures. They need to continually update their programs to stay abreast of those developments, including revisions that target in-house processes to encourage disclosures from whistleblowers. Failure to provide for such revisions places both a company and individuals at risk Whistleblower Protection Expanded and Includes Rewards In response…
