Secrets to a Successful Validation Project

Three major elements comprise validation projects in the biopharmaceutical industry: cost, schedule, and quality. If you can work within a budget, complete activities on time, and maintain regulatory-compliant documentation, then you significantly increase your chances for a successful validation project. Here we suggest ways you can improve these essential measurements with the help of a third-party validation team to achieve favorable outcomes. Team Selection The first key is building a validation team. Cohesion is critical for successful project management. All…

It’s Not Whether but Rather What and How to Implement

When considering integration of single-use technologies (SUTs or disposables) into a manufacturing process and facility, a number of criteria should be satisfied. These criteria govern both selection and implementation. Each criterion should be established by due diligence in which end-user requirements and the operation setting are considered carefully. Depending on a facility’s infrastructure and even a company’s business model, end users will define their criteria differently. Companies are driven to single-use technologies because of the simplicity and flexibility they impart…

Reconsidering the Supply Chain

An emerging challenge for biotech companies is understanding the bigger picture: How should manufacturing facilities be configured to link together process technologies? Should plants be highly flexible or focus on process standardization? How would a disruptive new technology affect current supply chains, and how could it be implemented? Meeting the challenge requires a complete and detailed understanding of supply chains. Much current focus in process development is on improving operations, with limited consideration to how improvements affect “big picture” variables.…

Validation of Adventitious Virus Removal By Virus Filtration

Regulatory bodies around the world expect downstream purification processes to demonstrate robust clearance of model adventitious viruses in time for execution of phase 3 clinical trials and product licensure (1,2,3). Model viruses selected for these studies should represent a diversity of viral physicochemical properties, and the clearance methods applied should include orthogonal mechanisms such as clearance based on size alongside chemical inactivation. Virus filtration is a critical unit operation used in numerous purification processes of monoclonal antibodies (MAbs), recombinant proteins,…

Sharing Is What It’s All About

Recently in Washington, DC, two conferences were held on the topics of cell and gene therapy. The California Separation Science Society (CASSS, www.casss.org) hosted a Well-Characterized Biological Products (WCBP) Chemicals, Materials, and Controls (CMC) strategy forum on “Current Practices for Assessing the Comparability and Stability of Gene Therapy Products,” while blocks away, Phacilitate hosted the 2008 Cell and Gene Therapy forum. At the WCBP CMC strategy forum, participants heard the US FDA–CBER perspective on the importance of comparability studies for…

In the Therapeutics Zone

Small molecules are still not providing cures for many diseases, and this is why biological therapies continue to be developed. They often offer greater convenience to patients, as well as longer lasting therapies,” says William Prather, MD, senior vice president of corporate development at the Israeli stem cell company, Pluristem. The therapeutics area at this year’s BIO International Convention will play host to many interesting technologies for producing and improving protein therapeutics, vaccines, and stem cells. Protein Therapies Remain Top…

Tackling Formulation and Delivery

The final hurdle in getting a product to market is the formulation and fill–finish step in process development. By their nature, protein therapeutics are more fragile and require a great deal of work to achieve product stability in final formulations. A cell line can be highly productive and efficient in protein production, but if you can’t stabilize the resulting protein and deliver it to patients intact, that’s a costly and useless exercise. The Formulation and Drug Delivery track of the…

Cutting Down Process Time and Costs

Because the biopharmaceutical industry operates as an industry rather than a nonprofit, the bottom line is an important consideration in every aspect of product design. From laboratory automation methods that speed discovery to streamlined manufacturing processes that incorporate the themes of operational excellence, Lean manufacturing, and quality by design, the industry is undeniably focused on minimizing cost and maximizing revenue. At the BioProcess International European Conference and Exhibition, the Scale-Up and Manufacturing track will focus on economic strategy and technology…

In the Facility Design Zone

As companies grow and expand their product offerings, it becomes necessary to consider manufacturing space. The decision to build is not made lightly, because CGMP manufacturing space comes at a steep price. Estimates range from $500 to $1,400 per ft2 to build new biopharmaceutical manufacturing space (1,2,3). As Jean-Francois Denault, Agnes Coquet, and Vincent Dodelet point out in their article in the February issue of BioProcess International, non-GMP biomanufacturing space comes at a much lower cost due to the lack…

In the Information Technology Zone

Successfully driving your global business requires vigorous, secure information exchange within your facility, from site-to-site, and with your partners and contract service providers. Tools to capture data in real time support decision making and enable companies to manage volumes of historical data needed for regulatory submissions. Software is available for data mining, managing clinical trial networks, and assessing toxicology data (among many other things). Information technologies in the biotechnology industry facilitate development and delivery of new therapies and diagnostics, improvements…
