Patient safety is at the heart of biopharmaceutical processing. Through viral processing, such as virus filtration or virus inactivation, viral contamination of the final drug product is prevented. In contrast to virus filtration, which involves the removal of viruses from a solution, virus inactivation stops the virus from being infectious. Three different technologies exist for virus inactivation: heat (for example, pasteurization), low pH treatment, and solvent/detergent treatment.
While methods of achieving viral safety vary, the underlying needs are the same regardless of the method applied:
We offer a variety of differentiated raw material solutions that address these requirements, while supporting patient safety.
High Temperature Short Time (HTST) pasteurization is the leading upstream method of viral risk mitigation for biopharmaceutical manufacturers striving to prevent costly contamination events. Our point-of-origin HTST raw material treatment offers an effective solution for high-risk raw materials such as glucose, achieving an approximate 6 log reduction (99.9999%) without impacting feed viability or performance. With our two redundant HTST trains we can provide supply chain security and flexibility of scale, offering HTST treated glucose for clinical and commercial scale applications. Outsourcing HTST pre-treatment offers a robust viral clearance option for large-volume, high-risk raw materials, allowing you to save on upfront capital expenditures while reducing your operational footprint.
An important virus inactivation method for monoclonal antibody (mAb) manufacturing, use of low pH reagents requires high-quality materials that can prevent microbial contamination and satisfy regulatory demands. Our reagents feature low bioburden and endotoxin levels, manufactured or purified under good manufacturing practices (GMP) for consistent high purity. To protect your API during this process step, our portfolio also includes a range of protein stabilizers.
All reagents are integrated with our Emprove® Program to simplify your raw material qualification and documentation process. Specifically for sterile applications, the Emprove® Expert portfolio was developed to meet the demands of high-risk applications. For example, our low pH reagents are backed by Emprove® dossiers that include:
Solvent/detergent treatments disrupt the lipid membrane of enveloped viruses and lead to inactivation, a critical step in many viral clearance strategies. They can be used as an orthogonal method for pH inactivation or as a replacement for pH inactivation in the production or extraction of pH-sensitive molecules. Our branded Emprove® products meet the high regulatory standards demanded of your raw materials, manufactured or purified to GMP standards for consistently high purity and process reliability.
As part of our industry-leading Emprove® Chemicals portfolio, all virus inactivation offerings are supported with comprehensive, up-to-date documentation to help you navigate regulatory challenges, manage risks, and improve processes.
