Review of a Supplier's Quality Control while Manufacturing Single-Use Systems

Nov. | 2016
  • Presenter: Michael Felo, Director Mobius Single-Use, Merck
  • Abstract
    Single-Use systems, enabling faster more cost effective bio-pharma manufacturing, must also meet high quality parameters and standards while conducting component qualification, manufacturing operations, inprocess testing, and final product release.

    For single use systems, quality control during the manufacturing process is critical. In a traditional stainless-steel system, the end user has significant control over the design, construction, qualification and validation, and maintenance of the system. When implementing a single-use system, the supplier of the single use product takes responsibility for many of these functions from the user. It is therefore important that the single use supplier has established and follows a strong quality control system. This presentation will highlight the quality systems, processes, facilities, and personnel required to assure the performance, robustness, and sterility of single use systems.

    In this webinar you will learn:

    • The process used to qualify components, suppliers and sub-suppliers
    • Managing documentation control, change control, process particulate control, risk mitigation practices
    • See examples of Extractables Testing, Validation of MFG processes, MFG Controls, Sterilization Qualification, Realease Testing and Certification, Integrity Assurance


Processing of Small Biological Molecules by TFF

Nov. | 2016
  • Presenter: Emily Peterson, Biomanufacturing Engineer, Merck
  • Abstract
    Strategies to overcome key limitations and challenges such as higher molecular osmotic pressure and lower membrane permeability when customizing small molecule (3-10 kDa) TFF processing.

    Due to their higher osmotic pressures and mass transfer coefficients, small molecules in the range of 3 – 10 kDa, like insulin, often require unique processing conditions as compared to those of larger molecules. TFF processing strategies developed for larger molecule applications may not be appropriate and can lead to an increase in process variability and sub-optimal performance.

    This webinar explores:

    • The key limitations and challenges typically observed with small biological molecule TFF processing
    • Explains the strategies required for optimal success with your TFF step

Broadening the Clarification Solutions for Vaccines: Insights into New and Evolving Technologies

Oct. | 2016
  • Presenter: Claire Scanlan, Process Development Scientist (PDS) & Manager for Central PDS Region in North America, Merck
  • Abstract
    One of the most critical steps in a vaccine manufacturing process is clarification, particularly harvest or lysate clarification.

    The methods employed can vary greatly due to:

    • The production system used
    • Product being harvested
    • The nature of the properties of the process fluid

    Centrifugation and/or microfiltration has historically dominated the vaccine process landscape, but the advent of newer normal flow filter options and the increased desire for disposable/single-use processes have expanded vaccine clarification choices.

    This webinar will detail the various clarification methods that can be successfully used for three vaccine types: viral, bacterial and polysaccharide vaccines. We will also focus on the wide-ranging uses of a novel depth filter for the efficient clarification of multiple vaccine types.

Novel Synthetic Adsorptive Depth Filter Media for CHO-S Harvest Clarification

Nov. | 2015
  • Presenter: John Amara, Ph.D. Senior Scientist, Biopharm Process Solutions R&D, Merck
  • Abstract
    Recent advancements in the productivity of upstream cell culture processes for the manufacture of therapeutic proteins, including monoclonal antibodies (mAbs), has resulted in greatly increased cell densities and higher levels of process-related impurities. These trends are placing an increased demand on existing harvest clarification technologies to remove biomass, including whole cells, cellular debris, and associated colloidal matter. Current depth filters may demonstrate an insufficient filtration capacity for these applications and often comprise naturally-derived components which require increased flushing to remove undesired organic and inorganic extractible components.

    Join us for this webinar as we report the design and performance characteristics of a novel synthetic depth filtration media that demonstrates a greatly increased filtration capacity and decreased effluent turbidity for the clarification of mAb from CHO-S harvests. When compared to commercial depth filtration media derived from natural components, this synthetic depth filter media is shown to have significantly decreased organic extractables and reduced WFI flushing requirements by TOC analysis. As an added benefit, this novel media is also shown to impart a modest HCP clearance capability through an adsorption mechanism. The impact of HCP clearance from the clarification step on several downstream process purification steps, including protein A capture chromatography and flow-through anion exchange chromatography will also be briefly explored.


Best Practices for Process Development Using Small-scale Millistak+® Filters

Sept. | 2014
  • Presenter: Kara Pizzelli, Manager of Process Develoment, Clarification, Merck
  • Abstract
    Clarification of mammalian cell culture harvest remains an important step in biotherapeutic production. With advancements in capacity of depth-filtration media and the move towards single-use, clarification via two-step depth filtration is a common approach at scales up to 2000 L. Despite the proliferation of template approaches for purification of monoclonal antibodies, the process development activities for clarification unit operations can still be challenging in terms of designing a small scale experiment which is representative of the large scale. This is because it is not possible to know in advance of the small scale trials which ratio of primary to secondary clarification filter to use, the appropriate flow rate to use and when breakthrough will occur on the two filters. Please join us as we discuss how to best standardize the process development approach for a two step clarification process to ensure the development of a robust, scalable unit operation while minimizing the necessary amount of process development work.


Clarification of Mammalian Cell Culture Feed Streams Using a Cationic Flocculant, pDADMAC, and Clarisolve® Depth Filters

Jan. | 2014
  • Presenter: Nripen Singh, Senior Research Scientist, Merck
  • Abstract
    Increasing cell culture densities and productivities during therapeutic protein (MAbs) production are placing a larger burden on downstream clarification and purification operations due to higher product and impurity levels. Traditionally, centrifugation and a combination of filtration techniques (tangential-flow filtration and depth filtration) have been widely used for clarifying these pretreated cell culture broths. However, the increased cellular debris present in these complex feed streams can prematurely foul the membrane and commercially available depth filters, adversely impacting their capacity and throughput. In this work, Merck has developed a cationic flocculant, Polydiallyldimethylammonium chloride (pDADMAC), as an effective pretreatment method for mammalian cell culture harvest which when coupled with Clarisolve® depth filters result in improved primary and secondary clarification for flocculated feeds. Potential benefits will be discussed, including more robust processing with a centrifuge and the potential to use filters in place of a centrifuge.
