Cell and gene therapy manufacturing consultancy eXmoor pharma has announced a strategic collaboration with Karoo CGT to accelerate the huge potential of UK gene therapies coming out of academia.

The funding gap between academic research and an investable proposition after Phase I/II trials is well reported. Karoo is building the expertise and infrastructure necessary to provide a fully integrated service to industry and academic programmes, from process review and development, to GLP and GMP manufacturing, through to clinical development and regulatory approval.

Ian Rhodes, CEO of Karoo, said: “We are delighted to be partnering with eXmoor, a company with a well-deserved reputation as a leader in the field of gene therapy commercialisation.”

eXmoor will provide process development services from its labs in Bristol, UK, to translate therapies from research into GMP manufacturing, ensuring scalability, risk/cost reduction and GMP compliance.

The consultancy will also design and project manage Karoo’s new manufacturing facility in Bristol. Patients will benefit from this collaboration as these gene therapies are accelerated through to commercialisation.

Angela Osborne, eXmoor managing director, said: “We fully support Karoo’s strategy to commercialise more of the UK’s excellent research for the benefit of patients and the economy.

“eXmoor is really pleased to be able to help with process development and facility design services, which will also support the company’s growth plans, particularly for our commercialisation labs.”

EIs vs BIs – Enzyme Indicators vs Biological Indicators

Obtaining accurate qualification results as quickly as possible is the minimum expectation and this is certainly the case when it comes to decontamination performance validation.

As such, the use of Biological Indicators (BIs) for decontamination qualification are a significant bottleneck and Enzyme Indicators (EIs) are an exciting potential solution for the biopharmaceutical industries.

     The Limitations of BIs

The conventional method for Vapor Phase Hydrogen Peroxide (VPHP) cycle development is to use resistant BIs to challenge the decontamination of enclosed spaces, which range from positive pressure isolators to whole rooms.

With this approach, the aim of the biodecontamination cycle is to demonstrate a 6-log reduction of the BI -despite this acceptance criterion usually being applied to terminal sterilisation processes, rather than for decontamination (i.e. disinfection).

To put this into context, the Environmental Protection Agency (EPA) classification of cleaning agents describes VPHP as a disinfectant treatment, for which demonstration of  4-log reduction of bacterial spores would be an acceptable result. However, BIs can only provide a kill (6-log)/no kill result.

This is a time-consuming process,  since a seven-day incubation period is required for definitive confirmation of a successful cycle. This in turn means that cycle development is costly and requires a huge amount of manual processing.

The solution?

Recent developments in thermally stable adenylate kinase (tAK) technology Enzymatic Indicators (EIs) are presenting an exciting alternative to the use of BIs, an alternative which is both rapid and capable of providing a much more precise indication of the level of disinfection.

In comparison with processes utilising BIs, cycles using EIs can be analysed rapidly, assuring confirmation of decontamination performance.

The tAK assay has been developed by Public Health England and Protak Ltd and is based on the principle that the  enzyme denatures slowly and in a highly predictable way on exposure to VPHP.

Any active enzyme remaining on strips following exposure are analysed on an indicator utilising a luciferin reaction which provides an immediate residual light output that is directly comparable to the remaining activity on the test strip.

The test strips can be manufactured to a high degree of consistency, with none of the quality issues that BIs may be vulnerable to.

Public Health England and Protak Ltd have carried out detailed enumeration studies using BIs and tAK EIs to develop inactivation profiles of tAK against log kill. In this way, a rapid and reliable assay for a range of desired log kills, including those suitable to demonstrate decontamination, is available to industry.

With the instant results provided by EIs using tAK before release, decontamination cycles can be quickly modified in the event of failure, meaning that cycle development is accelerated and the time to successful manufacture reduced.  Additionally, the technology means that microbiologists can obtain a full product decontamination and manufacturing history, lowering the risk of batch failures.

Next Steps

EIs could be the future of decontamination performance validation for reasons ranging from accuracy, to time to production and cost.

However,  the future of  EI solutions such as those using tAK (or  other developing technologies) requires further comparative work against previously validated systems. One entry possibility is the  validation of EIs alongside BIs during periodic revalidations of existing systems.

At eXmoor, we wanted to share our top 10 ‘must have’ requirements when sourcing a new site for a Generic ATMP Manufacturing Facility.

1. Area and Capacity

The prospective site area must be a suitable size to include the manufacturing site and warehouse, laboratories, offices, meeting rooms, reception and any other rooms or buildings that may be required. It’s important to consider all planned projects as these will give a good indication of the capacity required at the new site.

2. Height

In accordance with regulatory guidance, between 6-8m of space will be needed above the cleanrooms to include a walk-on ceiling which will allow these areas to be serviced from the outside. Space will also need to be made available for suitable heating, ventilation and air conditioning (HVAC) through the manufacturing and office areas. If the prospective building has sufficient height, the HVAC units could be located above the cleanrooms.

3. Vertical Distribution

Isolated lifts must be included for the movement and distribution of supply materials, waste and the final product. The number of lifts will depend on the layout of the prospective building. An additional large goods lift installed to allow for the vertical transportation of motors and spares to the plantroom (if required).As per point 2, a walk-on ceiling must be included above the cleanrooms to allow for servicing. Finally, you should allow for door heights of 2.7m to enable movement of large pieces of equipment throughout the facility.

4. Flows

When choosing a site, always consider whether there is a suitable flow and segregation of personnel, materials and waste. It’s also important to take into account the number of lifts and external docking stations.

5. Co-occupancy and Access

Ideally the site and facility chosen should always be single occupancy and should never share incoming or outgoing routes with other occupants of the building. It should not be possible to mix materials, personnel or waste routes with other occupants of the building, and no one should not be able to obtain unauthorised access to the facility (via lifts or stairs).

6. Utilities

The following raw utility services will need to be supplied as standard to the facility:

  • Mains pressure water
  • Surface and foul drainage
  • Gas (optional)
  • Electrical power

The following utilities should also be considered (if relevant to the facility):

  • Water for injection
  • Deionised water
  • Pure steam
  • Plant steam
  • Process chilled water
  • Clean in place
  • HVAC units to service cleanrooms – depending on concept design

7. Site

Ensure there is sufficient space on-site for the following items:

  • Chiller compound
  • Waste compound
  • Gases and LN2 area
  • Generator compound of sufficient size

The following items should also be considered in regards to the site proximity:

  • Not near to standing water or falls in an area with a high flood risk
  • Not near to heavily polluted industrial air exhausts
  • Not near to an adjacent large scale construction site
  • Ideally the manufacturing area would be >1m above the ground floor

8. Location

The location of the manufacturing facility is important to consider. It should be in close proximity to public transport links, amenities and in a safe working area. As first impressions are always important, the buildings and larger site should be smart and well maintained, portraying a professional and high quality image to others.

9. Structural

In the manufacturing area there will be large items of equipment that will impose a significant live loading on the floor, and there are therefore minimum loading requirements:

  • In the office / general areas, the minimum requirement for live floor loadings is 2.5kN/m2 above ground floor and 3.0kN/m2 at ground floor
  • In the manufacturing and plant areas, live loads need to be in accordance with the minimum standard (BS EN 1991-1-1:2002) of 7.5kN/m2, ideally 10.0kN/m2 to allow for 1000kg pallet (8.2kN/m2)

10. Support Areas

In the warehouse areas, storage should be of a sufficient capacity to allow various categories of materials and products to be stored in an orderly manner. Enough space should also be allocated to avoid any mix-ups or cross-contamination during the quality checking process and testing. Quality control laboratories should also be kept separate from the production areas. Rest and refreshment rooms should be kept separate from the production, storage and quality control areas. Toilets and washrooms should not directly link with production, storage and quality control areas.

In March this year the MHRA published its guidance on GxP Data Integrity.

We have welcomed the guidance at eXmoor. It provides specific information which is invaluable to companies around the practical steps which should be taken to ensure best practice at every stage of handling, managing and storing data.

In the past companies relied upon a perceived best practice along with general references to GAMP5 and 21CFR11 compliance, which has led to inconsistencies in the way data was managed. We believe this document will help companies understand the expectations around assurance of data integrity and that we will now see a more uniform approach and a move towards better managed data integrity practices.

The time is also right for this guidance. Technology and data storage products are now more advanced and becoming more common place within the industry; for example, the use of cloud-based technology for data storage has its benefits for the industry, but also holds risks which should be controlled.

We know from the manufacturers we work with that the guidance has helped them to review their data lifecycle and has resulted in updated processes in how they deal with data.

A major focus of the guidance has meant more emphasis on risk assessments of facilities and processes specifically around the data produced and how it is used. This is enabling a more holistic view of data management. The recommendation is to invest time in performing comprehensive Data Integrity Risk Assessments (DIRA) allowing companies to categorise their data management systems and to apply an appropriate level of control.

As part of this and to ensure compliance we are advising on how best to invest in the preparatory phase of any new facility or project and analysis of all the data which will be produced once operational.

Understanding the data lifecycle from start to finish, i.e. from when data is generated to when it is disposed of, is paramount. This then facilitates the validation of those systems used during that data lifecycle. The MHRA describes the data lifecycle as the ‘generation and recording through processing (including analysis, transformation and migration), use, date retention, archive/retrieval and destruction.’

Examples of where risk to data integrity can occur, which may impact on established working practices, are as follows:

  • Non-synchronised clocks: important when setting up systems that need to ensure the time and date on data is accurate and consistent ensuring concurrent recording of actions.
  • Access rights: unique user identification is vital to prevent unauthorised amendment of data. The guidance emphasises that having a single user access that does not uniquely identify the operator should not be used.

Companies with legacy systems may not have this feature. This will require them to assess the need for having other support systems in place (third party software or paper based) which provide a record of unique user identification.

  • Provision of a suitable work environment: As part of our facility design work we consider whether sufficient space has been allocated for an operator to be able to record data. Companies should always consider space for laying out of a batch record and SOP as part of the process.

Further features of the MHRA Data Integrity guidance:

  • Scribes: the use of scribes should be contemporaneous with the task being performed and the records should identify the person performing the task. The person performing the task should verify the actions taken at a suitable time after task completion.
  • Raw data: the guidance states that where the system permits dynamic storage then this cannot be replaced by paper systems.
  • True copies: these are considered to be a copy of the original record which has been verified as having the same information as the original.
  • Electronic signatures: Companies should ensure signature processes are appropriately validated to ensure that suitability and control is maintained.
  • Computerised systems validation: The MHRA has expressed the need for companies to look at all the systems they use within their processing and understand the computerised elements and the risks they pose and then apply a suitable level of control.

It is not acceptable to take a suppliers’ statement of compliance as the sole guarantee as to the acceptability of a computerised system – there needs to be some level of qualification performed by the company purchasing the system; the level required should be determined through risk assessment in the same manner as any processing equipment. As an example, an analytical instrument will be supplied with 21CFR 11 compliant software, but how the company intend to use the software needs to be assessed. This will need to take into account user set up and access rights, baseline configurations of the software, the programming of methods, data analysis, data reporting and data storage.

The importance of data management has never been more pronounced, and we believe this new guidance will provide both manufacturers and suppliers a clearer understanding as to the expectations from the competent authorities.

The hope is that companies will be able to manage their data more appropriately rather than taking the historical approach of ‘keep everything’ and that it will galvanise industry to use the data it generates to assist them in ensuring the quality of the products produced.
