Two filters better than one?
Regulatory authorities around the world promote risk assessment to ensure drug product safety. We interviewed Jerold Martin about recent discussions with regulators.Jerry, how is the expectation of regulators changing with regard to drug products that cannot be sterilized in their final container?
Sterilizing filtration is still the norm for these products. US FDA requires that sterilizing filtration be validated under worst case conditions (a service provided by Pall). EMA accepts this, but European GMP also recommends use of a second sterilizing filter (usually 0.2 micron rated) for added sterilization assurance.Using two filters to do one job seems excessive, do the regulators mandate this?
Only selectively. It's optional under US FDA guidance and the European GMP guidance is not universally mandated across Europe. However, some European country inspectors do expect it.Is integrity testing of both filters required?
Post-use integrity testing of the final sterilizing filter is always required. Testing of "double" (serial) filtration schemes, however, can vary. Where the first filter is used as a prefilter, it is not required to integrity test it because the product upstream of the final filter must be sampled for bioburden anyway. In a redundant scheme, if the second (final) filter passes a post-use integrity test, the product can be considered sterilized without testing the first filter. The benefit of redundancy is that if the final filter fails the integrity test, and the first filter passes, the product is still considered sterile. Where both filters are required for sterilization, then both will need to be integrity tested, at least post-use.How about pre-use testing?
Although some EU Inspectors are requiring pre-use testing after steam sterilization, pre-use testing does not affect patient safety and is primarily a business decision to avoid loss of the batch or rework in the event of a non-integral filter. It can ensure that shipping, handling and installation, as well as the sterilization process, have been done correctly.Lastly, can these test procedures be applied to single-use systems?
Certainly. For single use systems, Pall provides standard and customized designs suitable for use in compliance with regulatory requirements, as well as offering consultancy and training workshops on filtration system design, installation and integrity testing that many users find extremely beneficial.References:

Membrane Chromatography - A Flexible Solution to High Speed Contaminant Clearance
Continual improvements in upstream processing have led to higher protein expression levels, resulting in downstream titers in excess of 1g/L, even reaching 10g/L. These advances directly impact the downstream process, leading to potential bottlenecks. However, trends such as the use of higher capacity chromatography sorbents with improved selectivity, and an increase in the use of single-use technologies such as membrane chromatography, are gaining momentum in the biopharmaceutical industry.
Efficient contaminant removal from such processes is very challenging and this is an application where membrane chromatography is proving very popular. Its ease of operation, speed, and efficiency are helping to reduce processing time and cost, as well as improve overall process productivity. This webinar will provide the basic principles of membrane chromatography and illustrate specific customer applications of how this technology, when incorporated into the process, saves time and cost.The webinar is now available on-demand at www.pall.com/biopharmwebinars.
