Subject matter experts from the SFQRM Consortium has prepared this strategy roadmap with suggested actions and considerations to support the implementation of an effective risk-based approach:
The paper highlights a long-term desired view of CCIT to help develop equipment that can better meet end-user requirements. It will also provide confidence that CCIT methods can effectively demonstrate container integrity, such as microbial, headspace (gas, vacuum and moisture) and product integrity. It provides a long-term goal for companies that often use multiple CCIT technologies, with varied capabilities, to support the requirements of an expanding product portfolio. The URS will help overcome the significant inefficiencies that companies face. It will also help resolve the problem that the range of deterministic CCIT methods currently available do not represent a panacea for CCIT.
The purpose of an EM risk assessment (RA) is to provide information to determine how to distribute monitoring to best verify that processes are operating under control. This step-by step guidance covers the EM RA process and provides recommendations on monitoring sites and methods based on the relative probability of contamination industry guidance addresses these needs and attempts to capture best practices in a useable ‘toolkit’ format. The guide incorporates good practices from biopharmaceutical manufacturers and adheres to current regulatory guidelines.
It is generally recognized that post-use filter integrity testing is sufficient to detect filter failure and ensure patient safety unless there is a possibility that a filter passing the post-use test could have allowed bacterial penetration during filtration. This possibility is the phenomenon referred to as filter “flaw masking”, hypothesized to occur when, for example, a filter is damaged during sterilization such that it allows bacterial penetration, but that the damage becomes plugged during the filtration process to such an extent that it allows the filter to exhibit a passing post-use integrity test result. Two workstreams within the SFQRM consortium were designed specifically to evaluate the risk of this filter flaw masking and to understand in what conditions it might occur: Masking Studies, and Bacterial Challenge Test (BCT) Data Mining.
This article looks at the role of technology in the workplace and specifically how the Senior BioPhorum Connect group is addressing issues such as the use of remote working technologies, cyber security and digitizing the cGMP space.
There are now available to the biopharmaceutical industry several alternative and rapid microbiological methods (ARMMs) for the detection and enumeration of microorganisms during testing. Regulatory authorities are encouraging the biopharmaceutical industry to adopt innovative technologies. Together these methods will lead to improved monitoring and assurance of control of biopharmaceutical processes and manufacturing environments, as well as shortened cycle times in the supply chain. This paper addresses the need for a systematic and best practice approach to the evaluation, validation and deployment of these methods. The absence of such best practice has hindered the adoption of ARMMs, resulting in slow adoption. A nine-step framework and common language is described which can be applied by biopharmaceutical companies wanting to take advantage of the numerous benefits of ARMMs.
This article presents an update on the efforts of the joint PDA and BioPhorum collaboration workstreams—masking studies, historical data mining, filter manufacturing and use risk assessments and PUPSIT risk assessment and the development of a best practice guide.
This paper is one in a series of publications that are the result of the collaboration, and these should be considered together and viewed holistically in order to determine the best course of action with regard to PUPSIT. This paper examines the test process and looks at the results of potential masking of sterilizing grade filters.
This article draws conclusions from the scientific studies, workstreams, and publications delivered by the Sterile Filtration Quality Risk Management (SFQRM) consortium formed between BioPhorum and PDA. It uses those conclusions to provide guidance to industry (sterile drug manufacturers, filter suppliers, and regulators) on the use of quality risk management principles and scientific data to prevent undetected non-integral sterilizing filters.
Eudralex volume 4, Annex 1, the EU GMP for sterile products, requires that ″The integrity of the sterilised filter should be verified before use · · ·″ (1). Implicit in this requirement for a pre-use, post-sterilization integrity test (PUPSIT) is the rationale that the sterilizing filter could sustain damage during sterilization or use (i.e. subsequent to any pre-use test conducted prior to sterilization), causing a defect which would not be detected by the post-use integrity test. That is, that such a defect could be ″masked″ during filtration.
To assess whether a filter defect could be masked by partial filter plugging the Consortium evaluated the impact of bacterial retention testing on the bubble point (BP) of the test filters.
The paper concludes that filtration processes producing bubble point changes sufficient to present a risk of masking defects are not common, and detectable during the routine BCT. Thus the BP ratios observed during routine bacterial retention testing is one means to assess the potential of a given filtration process for masking of defects and can be considered when determining whether a PUPSIT should be implemented.
