The Pragmatic Clinical Trials Unit (PCTU) leads and supports clinical trials in which the primary question of interest relates to intervention effectiveness: whether an intervention works under real-life conditions.
It also leads and supports pilot studies for these trials. Currently, the unit focuses on trials of complex interventions, and on trials designed to understand processes explaining effectiveness, but also supports a small number of other pragmatic trials. In addition, the unit leads methodological research relevant to its focus.
The aim of the unit is to lead, support and encourage high quality pragmatic trials and pilot studies particularly where they fit with the research strategies of the two centres with which the unit is linked, or with the methodological interests of the unit.
The PCTU is based in the Centre for Primary Care and Public Health and linked to the Centre for Psychiatry. We have been conducting pragmatic clinical trials since the mid 1990s. We have considerable experience and expertise in primary care, community-based and mental health trials, and particularly cluster randomised trials and trials of complex interventions and behaviour change.
We are a UK Clinical Research Collaboration (UKCRC) registered clinical trials unit.
This unit receives National Institute for Health Research CTU Support Funding. This funding has been awarded to support the unit in developing and supporting NIHR trials.
What does a clinical trials unit do?
The UKCRC defines a clinical trials unit as a unit with overall responsibility for the design, recruitment, data management, publicity and analysis of multi-centred randomised controlled trials or other well-designed studies, working in any disease/topic area. There are more details on their website.
Some trials units are generic, covering all types of trial and disease areas. Other trials units, like the PCTU, have a more specific focus.
The PCTU is currently involved in these projects, which are at varying stages of completion and led by a variety of investigators. For further information please click on the title.

We undertake methodological research emerging directly out of discussions and deliberations around specific trials; this is an important part of the way in which we ensure that we stay at the forefront of the science and execution of pragmatic trials. Important and interesting questions can often be answered in a short time frame with no need for external funding. Senior academic staff also have their own longer term research interests. In particular we have long term interests in cluster randomised trials, pilot and feasibility studies, innovative trial design, and best practice in the design, analysis and reporting of trials. We try to keep a balance between following interesting new avenues and focusing on specific areas.

Staff role definitions
We want to ensure researchers get the best possible support from the Pragmatic Clinical Trials Unit and know who is responsible for which tasks within the unit. Different clinical trials units operate differently so this guide applies specifically to the Pragmatic Clinical Trials Unit.
Please see below outlines of some of the roles individuals can play within a trial. You may wish to refer to this guide in combination with the support services available when requesting PCTU support. Staff listed below are employed by the PCTU. Funding for their roles is incorporated in research grant applications, and for successful grants this funding is then paid by the organisation that receives the grant direct to the PCTU to pay these staff.
PCTU data managers: Tom Power, Mike Waring
We offer database design appropriate to the individual needs of each project we support. The data manager will develop appropriate data management strategies for trials and advise on their implementation. They will advise on current regulatory framework regarding data protection and data management procedures in compliance with data protection act and other regulations.
The data manager will advise on suitable database for individual study and set up databases in liaison with chief investigators, statisticians and health economists working on trials. Each database will have integrated data validation checks and full audit trails. Clinical and patient identifiable data are kept on physically separate databases. The data manager will advise on and set up data transfer systems and encryption systems so that all patient identifiable data is encrypted. The data manager will also advise on storage, back-up and archiving of data to ensure databases are regularly backed up to ensure data are safeguarded from accidental loss. In addition to this data management covers the following tasks:Advise on case report form (CRF) design
- Agree with chief investigator time line for database set up and database lock
- With chief investigator, draw up trial data management SOPs.
PCTU health economist: Natalia Hounsome
In some clinical trials, it can be important to compare how much different treatments cost, as well as how well they work. This can be particularly important when two (or more) treatments are equally effective, but differ considerably in their costs. An economic evaluation as offered by our health economist will ensure that all costs (treatment, care and recovery, as well as the costs of prevention, research and training of healthcare personnel) have been considered when the trial results are presented.
The health economist will:
- Develop plans for economic analyses and advise on appropriate data collection
- Collaborate with statisticians and data managers working on trials to ensure appropriate data management systems
- Carry out economic analyses for trials including modelling
- Input into report and publication papers.
Quality Assurance Officer
PCTU QA managers: Anitha Manivannan
The quality assurance officer will train trial staff in PCTU and Joint Research Office's Standard Operating Procedures (SOPs) as relevant to their work, liaise with chief investigators regarding set up trial master files and carry out audits of the trial master file for ongoing quality assurance. They will also ensure compliance with GCP regulations and advise on staff GCP requirements, clinical trial regulatory requirements, adverse event reporting and on PCTU support available.
PCTU Head of Operations
PCTU Head of Operations: Tahera Hussain
The PCTU Head of Operations will act on behalf of the unit director and negotiate with chief investigators over PCTU involvement in trial, agreeing costs and timing. The Head of Operations will liaise with the Joint Research Office over costings for PCTU staff and with grant holding organisation regarding transfer of funds for PCTU support. They manage the PCTU budget and also liaise with R&D departments to ensure necessary contracts are in place.
PCTU administrator: currently vacant
The administrator acts as first point of contact for researchers wishing to collaborate with the PCTU. Day to day admin within the unit covers tasks such as:
- Filter enquiries to the unit, liaising with unit staff as necessary
- Maintain records of all agreements between CIs and PCTU
- Maintain database logging PCTU activity
- Maintain database of active and completed projects supported
- Administrative support for supported projects includes design and maintenance of trial websites for all supported projects.
Further administrative support can be arranged (mainly for trials led from within the Centre for Primary Care and Public Health) to include for example trial correspondence, liaising with research staff or setting up site files as required.
PCTU statisticians: Lauren Bell; Lee Beresford; Claire Coleman; Gordon Forbes; Lauren Greenberg; Brennan Kahan; Vichithranie Madurasinghe; Nadine Marlin; Claire Nightingale; Neil Wright
Statistical support is required at all stages of a project starting with input into protocol development. Further support includes developing analysis plans, performing randomisation or minimisation for trials, liaising with health economist and data managers working on trials, or other studies under the remit of the PCTU, to ensure appropriate data management systems are in place and of course carrying out statistical analyses. Other tasks performed by the statisticians are:
- Carry out sample size/power calculations
- Input into CRF/data capture tools development
- Write detailed statistical analysis plans
- Liaise with data manager to ensure adequate cleaning of final dataset
- Write and check Stata .do files or other appropriate programmes to perform data manipulation and analysis
- Produce reports for the Data Monitoring Committee, Trial Steering Committee or funder as necessary
- Perform any pre-planned interim analysis blinded to treatment allocation. If unblinded analysis is necessary, such analysis will be performed by another statistician in the PCTU.
- Attend trial/study team meetings where possible
- Liaise with data manager and trial manager throughout the duration of the trial to ensure data quality and integrity
- Write a final statistical report
- Authorship on publications arising from projects
- Respond to publication reviewers' comments.
Trial coordinator / Trial manager
PCTU trial managers and coordinators: John Allotey; Sybil Bannister; Lesley Dibley; Julie Dodds; Jessica Gavira; Eion Golden; Wai Yee James; Paula John; Doris Lanz; Bev MacLaughlin; Jacqueline Mansfield; Katie Myers-Smith; Sian Newton; Hana Pavlickova; Sarrah Peerbux; Anna Placzek; Ewelina Rogozinska; Irene Simmonds; Sarah Snuggs; Natasha Stevens; Shiva Taheri; Ann Thomson; Jenn Walker; Karolina Witt
The trial coordinator or manager will maintain general oversight of trial coordinating participating sites as necessary over the full duration of the project. They also manage the trial administration by ensuring that files and documentation is up to date and complete, by keeping accurate written and computerised secure and safe records. They will ensure that all clinical trials procedures are fully compliant with the PCTU's and sponsor's standard operating procedures as applicable to the trial.
They will act as the point of contact for all external and internal agencies and provide efficient day-to-day management of the trial.
This includes but is not limited to:
- Maintain confidentiality and security of patient and staff records
- Recruitment, retention, training, appraisal and supervision of trial team members.
- Establish procedures to ensure adherence to trial protocols and administrative requirements
- Ensure the timely recruitment of trial participants with secure randomisation processes and subsequent efficient and effective data management
- Monitor the trial progress to ensure compliance with and adherence to the project plan and to identify, evaluate and rectify problems
- Manage the trial budget(s) and maintain the accounts
- Coordinate the preparation and publication of data, reports and information, ensuring that these meet legislative, contractual and ethical requirements
- Liaise with the Trials Steering Committee and Data Monitoring and Ethics Committee with a particular view on compliance with Research Governance, Good Clinical Practice, Data Protection and Ethical Requirements
- Provide regular and ad hoc information, both written and verbal, to all the trial participants, funders and sponsors. This could include reports, updates, guidance, proformed commitments and, possibly, a Newsletter.
- Work with the Chief Investigator to ensure that the trial is meeting its targets, is producing meaningful output and to predict and plan any changes that warrant requests to changes in protocol, funding or time
- Ensure the inclusion of patient representatives at the appropriate levels and times
- Plan and support meetings and work of the various groups and bodies associated with the trial.
The trial coordinator will also have access to additional advice and assistance from the PCTU's senior trial manager as well as the quality assurance officer. This will be particularly relevant at approval stage, when liaising with various external agencies to gain the appropriate approvals for the project, and in the event of any non-compliance or serious adverse events.
PCTU trial monitor: Jeanette Hansen
PCTU will monitor and/or audit PCTU supported CTIMP and non-CTIMP trials on a risk-based basis as agreed by the sponsor. The monitoring plan will be agreed by the CI, sponsor and PCTU QA manager prior to study initiation.
Tasks performed by the monitor are:
- Source data verification
- Monitor progress of trial
- Confirm that all adverse events are being documented and reported as necessary
- Check CI adheres to their responsibilities according to GCP and delegates responsibilities appropriately
- Scrutinize trial related documents
- Examine research staff on their knowledge of the protocol
- Ensure that the trial is being conducted according to GCP, clinical trial regulations and sponsor requirements.
- The purpose is to verify that reported trial data is correct, complete and verifiable (ICH GCP 1.38 and 5.18.1). Findings are reported to the PCTU QA manager and sponsor via a monitoring report.
What PCTU does
What is a clinical trial?
We use the definition of a clinical trial as proposed by the International Committee of Medical journal editors:
"Any research project that prospectively assigns human subjects to intervention and comparison groups to study the cause-and-effect relationship between a medical intervention and a health outcome. By 'medical intervention' we mean any intervention used to modify a health outcome. This definition includes drugs, surgical procedures, devices, behavioural treatments, process-of-care changes, and the like."
This definition is wider than other definitions, some of which restrict the use of the word 'clinical' to trials in which medicinal products are being investigated. Many of the trials the PCTU leads and supports are not trials of investigational medicinal products.
What is an investigational medicinal product (IMP)?
Article 2 (d) of the EU Clinical Trials Directive 2001/20/EC provides the following definition for an IMP:
"a pharmaceutical form of an active substance or placebo being tested or used as a reference in a clinical trial, including products already with a marketing authorization but used or assembled (formulated or packaged) in a way different from the authorised form, or when used for an unauthorised indication, or when used to gain further information about the authorised form."
The PCTU does lead and support trials of investigational medicinal products but these are in the minority.
Trials led by the unit
Trials linked to the unit
These include trials led from elsewhere in Barts and The London School of Medicine and Dentistry or Barts Health NHS Trust, and trials led from outside these organisations. The last category includes multi-centre trials led from other centres, where the unit may sometimes have joint responsibility for aspects of trial design and analysis together with another clinical trials unit. Trials from outside the Centres of Primary Care and Public Health and Psychiatry can be linked to the unit if they are trials of effectiveness fitting broadly with either the research strategies or methodological interests of the unit.
How to obtain support
The initial request has to be received at least 12 weeks before the intended application's submission date (outline application if applicable).
Level of support
Usually, the PCTU would expect to provide all the services listed under details of support available, dependant on the potential costs for support and the capacity of the PCTU. In some cases the level of support will depend on the costs involved and the capacity of the PCTU. We are able to offer bespoke advice tailored to the individual needs of each supported project but will only engage in high quality, methodologically sound trials where we also have academic input. All trials supported by the PCTU must adhere to relevant Standard Operating Procedures already in place.
Once the trial chief investigator and the PCTU manager are in agreement about the level of support and costs, approval for support must be gained in writing (usually by email) from the PCTU director or manager. This approval must be gained before any funding applications are submitted and must include full details of the support and cost agreed upon.
Support can be accessed during protocol development and during the trial itself. Support accessed during protocol development is not charged for and must be negotiated depending on PCTU capacity. This support is important in relation both to successful funding and successful projects and we encourage all researchers to take full advantage of the support offered this stage.
We often encourage researchers to also link with the London Research Design Service for further support in developing their application.
Services accessed after trial funding is secured must all be adequately costed and agreed beforehand. We will expect to recover the true costs of our engagement in a study in terms of staff costs and consumables.
Such funding supports staff employed by the unit to work across a range of trials, such as data managers, statisticians, health economists, quality assurance officers, administrators and the unit manager.

The chief investigator is responsible for negotiating level and cost of support and for gaining approval for support by the PCTU (as specified in PCTU support), and for clearly specifying the role of the PCTU and corresponding financial implications in any funding application.
The PCTU works to a number of SOPs specific to the PCTU. The chief investigator is responsible for ensuring that trials linked to the PCTU follow these SOPs. Compliance will be monitored by the PCTU. The responsibilities of the chief investigator as detailed in the ICH Good Clinical Practice guidelines are listed below:
- Qualifications and agreements (GCP, delegation of trial-related duties)
- Adequate Resources – time, funding, demonstrate ability to recruit (via pilot etc)
- Medical care of trial subjects
- On-going communication with REC/MHRA throughout trial (amendments, annual reports etc)
- Ensure full compliance with protocol and document deviations and submit amendments to REC
- Investigational Product (if applicable) - responsible for IMP accountability at site/s (can be assigned to appropriate pharmacist)
- Randomization Procedures and Unblinding – responsible for following trial's randomization and blinding/unblinding procedures (if applicable)
- Informed consent – responsible for following GCP guidelines on informed consent
- Records and Reports – follow GCP guidelines on CRF and source documentation, maintenance of trial documentation, financial agreements and archiving
- Progress Reports – provide written summaries to REC (annually or more frequently if requested) and sponsor and REC regarding substantial changes to trial
- SAEs - responsible for ensuring all SAEs reported to sponsor (‘Sponsor’ is an individual, company, institution or organisation which takes responsibility for the initiation and management of the clinical trial)
- Premature Termination or Suspension of Trial – Responsible for ensuring trial subjects, institution sponsor and REC are promptly informed if trial ends prematurely or is suspended
- Final Report – ensure that final report provided to institution, REC, regulatory authorities and sponsor

Inside a Clinical Trials Unit
This course will be of interest to new principal investigators and other researchers who have not previously worked closely with a Clinical Trials Unit (CTU), and who want to learn more about the design and conduct of pragmatic clinical trials and the nature of CTU involvement. The course is an immersive experience including observation of real-life trial processes and the work of CTU staff, and one-to-one time spent with knowledgeable tutors.
Registration on one of our 3-day taught courses (Introduction to Design, Conduct and Analysis of Pragmatic Clinical Trials, or A Practical Guide to Cluster Randomised Trials (Introductory Course)) is also included in the price. The course will be based at the Pragmatic Clinical Trials Unit (PCTU) at Barts & The London School of Medicine & Dentistry.
In addition to the 3-day taught course, the total time commitment amounts to no more than 1 hour a week, spread over a period up to one year, though this can be scheduled flexibly to suit your needs. You will benefit from:
- a lead tutor who will be your main point of contact with PCTU, who will help you to plan a series of opportunities (at least 10 hours in total) for observing meetings and other PCTU activities encompassing the complete natural history of a trial;
- 6 one-to-one 1-hour sessions with your lead tutor, spread over the year, to consolidate what you have learned and discuss issues in depth;
- 6 one-to-one 1-hour sessions, spread over the year, with a specialist tutor from one of four PCTU teams (depending on the area you particularly want to focus on): statistics, data management, quality assurance or trial management.
Some of your time will be devoted to self-directed learning: your lead tutor will give you resources and practical tasks suited to your study programme, and there will be space in PCTU for hot-desking and engaging more fully with the Unit.
You can start the course at any time during the year, but the number of places at any one time is very limited, and you will need to give us at least 1 month’s notice of your intended start date, so we advise that you contact us as early as possible if you are interested in joining.
