FAT and SAT, a critical step for the introduction of new equipment

There are two key moments to be faced to introduce a new piece of equipment in a pharmaceutical plant: a factory acceptance testing (FAT), usually performed by its manufacturer to verify the new equipment meets its intended purpose, prior to approve it for delivery and once arrived at its final destination and installed, a site acceptance testing (SAT) run by the purchasing company and is part of the commissioning activity.

According to an article published in Outsourced Pharma, the commissioning of a new piece of equipment poses many challenges, and criticalities needs to be considered both from the business and regulatory point of view. Pharmaceutical plants are very complex and often customised upon the specific business needs, and the delivery of a new equipment requires the interaction of many different parties, both internal and external to the purchasing company. FAT, SAT and commissioning activities require a careful planning and detailed responsibilities for all participating parties to be included within the Commissioning and Qualification Plan (CQV plan). A possible responsibility matrix is suggested by the authors to provide clarity and ensures ownership of activities.

FAT, assessing the equipment at the manufacturer site

FAT and SAT testing involve the visual inspection of the equipment and the verification of its static and/or dynamic functioning, in order to assess the actual correspondence to the user requirement specifications (URS). While FATs are usually based on simulations of the equipment’s operating environment, SAT testing occurs at the final site after installation, thus it reflects the real operating conditions and environment in order to support qualification.

There are many different elements to be considered during FAT testing, including for example verification of the existing site drainage, piping, or room dimensions, or the position of the handle for accessibility, as well as software design specification, interface, and device integration.

The FAT exercise is always highly recommended, as it is essential to solve in advance (before shipment to the final destination) any error or malfunctioning of the equipment, that otherwise might occur at the purchasing company’s site. This results in the optimisation of the delivery and commissioning process, with important savings in terms of both time and costs for the purchasing company. To ensure for the transparency of FAT testing, the entire procedure (that requires usually 1-3 days, depending on the complexity of the equipment to be verified) is usually performed in the presence of a third party inspector and customer representative.

A comprehensive set of documentation should be always available to support FAT, including URS, drawings, checklists and procedures, calibrations and certifications, data sheets, references, etc. Raw data acquired during FAT are transmitted to the customer for analysis and validation. FAT should take into consideration all aspects relevant to the evaluation of the safety and functionality of the equipment and its compliance to URS, GMPs and data integrity. To this regard, it is also important for the engineering team called to run the new equipment at its final location to learn and share knowledge with the manufacturer along the entire commissioning process, so to increase the first-hand direct experience. According to the article, this is also critical to authorise the shipment of the equipment to the final destination, a step that should always be performed by an authorised, trained, and approved subject matter expert.

 SAT acceptance testing

All criticalities emerged during the FAT exercise are then checked again at the final site, after installation and verification; additional test cases may also be added to the SAT protocol to check for potential failure modes. SAT testing is performed once all connections between the new equipment and other machines/softwares are in place, under the real operating parameters, and may be witnessed by a representative of the equipment’s manufacturer.

Results from SATs may thus differ from those obtained from the FAT previously run by the manufacturer. From the regulatory point of view, SAT testing is a key element to demonstrate the compliance of the equipment to GMP requirements and to support the overall quality and safety of pharmaceutical productions. In this case too, many are the possible elements to be inspected and verified, including interlocks, ventilation, internal box pressure, electrical/hydraulic connections and safety systems, visual checks of components, training of the operators, etc.

A plan for each testing phase

FAT planning begins at the very moment of the purchasing company placing the order for the new equipment, and it has to reflect all URS to be checked for acceptability of the manufactured apparatus. This step in the design is critical and calls for a strict and positive communication between the manufacturer and its customers, a key point to take into consideration all elements that should enter the project.

All identified items and procedures to be challenged during FAT and SAT testing are usually addressed within the CQV plan, that connects the design phase to user requirements specifications and the other elements impacting the commissioning and qualification processes (i.e. system impact assessment, design specification, functional risk assessment, hardware / software specifications, Installation / Operational / Performance Qualification), including deviations and change management. The plan specific to SAT testing should include the scope, test specifications and logs, a test summary, the Commissioning report and the final Certificate of Acceptance.

Transparency and a robust statistical approach should represent main targets along the entire commissioning and validation procedure, that may be run with the assistance of external consultants. All activities that shall enter the regulatory dossiers should always be justified and documented, also under the perspective of data integrity. The Outsourced Pharma’s article also suggests paying a particular attention to controls on data provided by the manufacturer in the case a risk-based leveraging is applied.


Automation of aseptic manufacturing

The pharmaceutical industry is often the last industrial sector to implement many new manufacturing and methodological procedures. One typical example is Lean production, those concepts were developed in the automotive industry well before their adoption in the pharmaceutical field. The same may also apply to automation: it appears time is now mature to see an increasing role of automated operations in the critical field of aseptic manufacturing, suggests an article by Jennifer Markarian on PharmTech.com.

The main added value of automation is represented by the possibility to greatly reduce the risk of contamination associated to the presence of human operators in cleanrooms. A goal of high significance for the production of biotech, advanced therapies, which are typically parenterally administered. Automation is already taking place in many downstream processes, for example for fill/finish operations, packaging or warehouse management.

The advantages of the automation of aseptic processes

The biggest challenges engineers face when designing isolated fill lines are fitting the design into a small, enclosed space; achieving good operator ergonomics; and ensuring all systems and penetrations are leak-tight and properly designed for cleanability and [hydrogen peroxide] sterilization,” said Joe Hoff, CEO of robotics manufacturer AST, interviewed by Jennifer Markarian.

The great attention to the development of the Contamination Control Strategy (CCS) – which represents the core of sterile manufacturing, as indicated by the new Annex 1 to GMPs – may benefit from the insertion of robots and other automation technologies within gloveless isolators and other types of closed systems. This passage aims to completely exclude the human presence from the cleanroom and is key to achieve a completely segregated manufacturing environment, thus maximising the reduction of potential risks of contamination.

The new approach supports the pharmaceutical industry also in overcoming the often observed reluctance to innovate manufacturing processes: automation is now widely and positively perceived by regulators, thus contributing to lowering the regulatory risks linked to the submission of variations to the CMC part of the authorisation dossiers. High costs for the transitions to automated manufacturing – that might include the re-design of the facilities and the need to revalidate the processes – still represent significant barriers to the diffusion of these innovative methodologies for pharmaceutical production.

The elimination of human intervention in aseptic process was also a requirement of FDA’s 2004 Guideline on Sterile Drug Products Produced by Aseptic Processing and of the related report on Pharmaceutical CGMPs for the 21st Century: A Risk-Based Approach. According to Morningstar, for example, the FDA has recently granted approval for ADMA Biologics’ in-house aseptic fill-finish machine, an investment aimed to improve gross margins, consistency of supply, cycle times from inventory to production, and control of batch release.

Another advantage recalled by the PharmTech’s article is the availability of highly standardized robotics systems, thus enabling a great reduction of the time needed for setting up the new processes. The qualification of gloves’ use and cleaning procedures, for example, is no longer needed, impacting on another often highly critical step of manufacturing.

Easier training and higher reproducibility of operative tasks are other advantages offered by robots: machines do not need repeated training and testing for verification of the adherence to procedures, for example, thus greatly simplifying the qualification and validation steps required by GMPs. Nevertheless, training of human operators remains critical with respect to the availability of adequate knowledge to operate and control the automated systems, both from the mechanical and electronic point of view.

Possible examples of automation in sterile manufacturing

Robots are today able to perform a great number of complex, repetitive procedures with great precision, for example in the handling of different formats of vials and syringes. Automatic weighing stations are usually present within the isolator, so to weight empty and full vials in order to automatically adjust the filling process.

This may turn useful, for example, with respect to the production of small batches of advanced therapy medicinal products to be used in the field of precision medicine. Robots can also be automatically cleaned and decontaminated along with other contents of the isolator, simplifying the procedures that have to be run between different batches of production and according to the “Cleaning In Place” (CIP) and “Sterilisation In Place” (SIP) methodologies.

The design and mechanical characteristics of the robots (e.g. the use of brushless servomotors) make the process more smooth and reproducible, as mechanical movements are giving rise to a reduced number of particles.

Examples of gloveless fully sealed isolators inclusive of a robotic, GMP compliant arm were already presented in 2015 for the modular small-scale manufacturing of personalised, cytotoxic materials used for clinical trials.

Maintenance of the closed system may be also, at least partly, automated, for example by mean of haptic devices operated by remote to run the procedure the robotic arm needs to perform. Implementation of PAT tools and artificial intelligence algorithms offers opportunities for the continuous monitoring of the machinery, thus preventing malfunctioning and potential failures. The so gathered data may also prove very useful to run simulations of the process and optimization of the operative parameters. Artificial intelligence may be in place to run the automated monitoring and to detect defective finished products.

Automated filling machines allow for a high flexibility of batch’s size, from few hundreds of vials per hour up to some thousands. The transfer of containers along the different stations of the process is also automated. The implementation of this type of processes is usually associated with the use of pre-sterilised, single-use materials automatically inserted within the isolator (e.g. primary containers and closures, beta bags and disposal waste bags).

Automation may also refer to microbial monitoring and particle sampling operations to be run into cleanrooms, in line with the final goal to eliminate the need of human intervention.

Comparison of risks vs manual processes

A comparison of risks relative to various types of aseptic preparation processes typically run within a hospital pharmacy and performed, respectively, using a robot plus peristaltic pump or a manual process was published in 2019 in Pharm. Technol. in Hospital Pharmacy.

Production “on demand” of tailor-made preparations has been identified by authors as the more critical process, for which no significant difference in productivity is present between the manual and automated process. The robotic process proved to be superior for standardised preparations either from ready to use solutions or mixed cycles. A risk analysis run using the Failure Modes Effects and Criticality Analysis (FMECA) showed a lower level of associated risk.


Webinar: PBPK Modelling and Simulation – A valuable tool for Pharmaceutical Development

, , , , , , ,

Over the last 20 years Physiologically – Based Pharmacokinetic (PBPK) Modelling and Simulation has developed and is now used extensively within Discovery and Development in the Pharmaceutical Industry. Its adoption has been driven by the availability of commercial software platforms and a realisation of the benefits to be gained including the potential to reduce the number of in vivo studies performed. 

In EIPG’s and PIER’s next webinar, to be held on 21st October 2021 (17.00 CEST), Jonathan Brown will cover an introduction to PBPK modelling, what it is and how it can be applied to support Chemistry, Manufacturing and Controls (CMC) development. It will provide an overview of usage in oral, small molecule development, supported by examples from the areas of biopharmaceutics and formulation development. Current and potential future applications of PBPK modelling in Quality and Regulatory fields will also be discussed.
