Paragraph

The LSHTM Clinical Trials Unit (CTU) is based within the largest school of public health in Europe with a global network of collaborators from over 70 countries.

The CTU has an international reputation for its clinical trials, especially in the areas of trauma and emergency care, cardiovascular disease and maternal health.

We value working with patients and the public and they are at the centre of our research activities.

The CTU is accredited by the UK Clinical Research Collaboration.  

Our research portfolio includes:

  • trials of drugs
  • complex interventions
  • mechanisms of disease and treatments
  • cohort studies and systematic reviews of evidence

We aim to improve the efficiency of trials to enhance quality, limit cost and reduce our carbon footprint.  We do this by examining our trial designs, participant recruitment and retention strategies, and by monitoring how we conduct trials.

As well as running our own trials, we offer support and advice to colleagues and external parties planning clinical trials through our trial adoption process.

Who we work with

We work closely with funders and research partners around the world.  We also collaborate with LSHTM research centres and teams.

Our partners

Within LSHTM we liaise closely with the:

Analysis of Clinical Trials is one of  the core themes of the Centre for Data and Statistical Science for Health. The Centre for Evaluation’s Quantifying Impact theme brings together specialists in the design, conduct, analysis, and reporting of evaluations that assess and quantify the impact of complex public health interventions, policies or health system changes.  Its sub-themes are: cluster-randomised trials, stepped wedge trials, non-randomised and quasi experimental trials and pragmatic trials.

National co-ordinating centres

We have long-standing partnerships with research institutions in Nigeria, Pakistan and Zambia that act as national coordinating centres for many of our trauma and maternal health trials:

Meet the team

Our expert team includes clinical trialists, methodologists, statisticians, trial managers and administrators, data managers and IT systems and software development experts.

Our approach

  • Identifying cost-effective interventions for problems of global health importance including a range of clinical trials in a number of research themes
  • Promoting the efficient conduct of clinical trials through statistical data monitoring of trials, developing in-house IT and database systems (including central randomisation, secure servers, trials databases and adverse event reporting systems);
  • Maximising the use of clinical trial data by making anonymised datasets available to investigators beyond the original research team, within and external to LSHTM;
  • Maximising the impact of clinical trials through prognosis research to improve clinical decision making, counsel patients and to facilitate clinical research;
  • Increasing the health impact of clinical trials through more effective dissemination of trial results;
  • Achieving more effective engagement in the design, conduct and dissemination of trial by increasing the emphasis on patient and public involvement in our trials.

Current trials

Cardiovascular

The CTU cardiovascular team specialises in the design, conduct and analysis of pragmatic multicentre clinical trials, often with simple interventions or treatment strategies.

We have developed strong links with many of the top cardiovascular hospitals in the UK over the past 30 years, beginning with the BHF-funded RITA, RITA-2 and RITA-3 trials. Through these collaborations with sites we aim to develop efficient trials which can be conducted with minimal complexity while delivering important results.

As well as trial design, conduct and management we have world renowned expertise in statistical methodology, analysis and interpretation of large scale cardiovascular trials. This includes development of novel statistical methods (such as the Win Ratio) and publication of educational articles specifically in the design and analysis of cardiovascular trials.

We also support the statistical design, data monitoring, analysis and publication for a larger set of major industry sponsored international cardiovascular trials.

We have direct experience in delivering emergency research in the NHS, for example in advance of primary percutaneous coronary intervention (PCI) (ERIC-PPCI), in cardiac arrest (ARREST), or within primary care (StatinWISE). We have worked on trials in coronary artery bypass surgery (ERICCA, RITA, Tight K), remote ischaemic pre-conditioning (ERICCA, ERIC-PPCI, REPAIR), percutaneous coronary Intervention (RITA, RITA-2, RITA-3, REVIVED, ERIC-PPCI, CHIP-BCIS3) and transcatheter aortic valve implantation (BHF PROTECT-TAVI).

Paragraph

We are fully accredited as a UK Clinical Research Collaboration (UKCRC) Clinical Trials Unit and offer support for clinical trial design, planning, implementation and analysis through our trial adoption process. We adopt trials led from within and outside LSHTM. 

Trial adoption process

Enquire

  • Submit an enquiry using our CTU collaboration enquiry form
  • Most enquiries will already have a provisional proposal and a funding source in mind.
  • All proposals must plan to include a member of the CTU management group as a co-applicant to be considered for adoption.

Outline review

  • We will respond to your enquiry within 10 working days.
  • If we can progress your enquiry, we will provide preliminary feedback and arrange to discuss it with you. 

Full review

  • A member of our team will work with you to develop your proposal.  This will include costing for the role that the CTU will play if the application is successful.
  • A well-developed draft proposal will undergo full review by an independent member of the CTU management group.
  • Successful review results in the trial being ‘CTU Adopted’.

When reviewing proposals, we look for trials that satisfy our review criteria:  

Review criteria

Necessary 

The evidence-base (including a formal review of relevant Randomised Controlled Trials) clearly demonstrates that the research is needed.

Important

The trial addresses a question that is clinically important, such as areas of crucial evidence gaps, or areas of controversy or high variation in clinical care.

Relevant

The trial is relevant to the study population.

Feasible

To ensure trials progress in line with expectations, in particular participant recruitment and retention, there is an appropriate blend of experience and clinical credibility in the research team.

The assumptions behind the study stand up to critical review, and evidence is provided that these assumptions are reasonable.

If no such reassurance is possible, a pilot study or early returns as the study commences will be needed.

Methodologically sound

The study is optimally designed, with appropriate analysis, suitable methods of managing and conducting the trial, the trial will be registered and there is full commitment to publish results in peer-reviewed journals.

Financially viable

Staffing and consumable costs are adequately funded and deliverable in the proposed timelines. The CTU involvement is appropriately financed.

Aligned

The study is aligned with the CTU’s areas of clinical trial excellence.

Ethically sound

High ethical standards are evident, and study risks and benefits have been properly considered.

Although some trials may be successful on all of the above criteria, if at the point of application the CTU does not have capacity to take on the necessary responsibilities, we will not adopt the trial.

Adoption

  • Once a trial has been adopted, the CTU commits to its responsibilities as detailed in the proposal and related documentation.
  • The progress of all CTU adopted trials is reviewed at regular intervals by the CTU management group, with particular attention paid to recruitment, retention and any serious adverse effects (SAEs), deviations or major risks identified.

Research methods, trial design and analysis 

Our team of epidemiologists, systematic reviewers and trialists have expertise in the design, conduct, analysis and reporting of international randomised controlled trials across a range of subject areas and methodologies.  We have experience in designing and implementing trials in a wide range of socio-economic settings and geographies. Our expertise includes:

  • systematic review methodology
  • clinical trial design
  • methodological issues in clinical trials
  • scientific writing
  • effective dissemination of research findings.
Trials and statistical methodology, monitoring and health economics

Our statisticians, trialists and health economists guide the design, feasibility, conduct, analysis and reporting of studies and we have strong links with the Centre for Statistical Methodology.

Our team of statisticians and health economists are specialists in:

  • statistical analyses
  • statistical monitoring
  • health economic evaluation
  • cost-effectiveness modelling
  • report writing and publication
  • dissemination of trial results.

We have expertise in the development of statistical and trials methodology, analysis and interpretation of large-scale trials as well as providing educational resources for the explanation and implementation of these key concepts in clinical trials. We have developed innovative and efficient methods for improving trial recruitment and ensuring high follow up. This methodological and educational work is undertaken to directly improve current and future clinical trials. For example, the development of the Win Ratio has led to this being adopted widely within the cardiovascular community including as the primary outcome for a number of major trials.

We are also skilled in using statistical methods to monitor trial data as it is collected. This is an efficient and cost-effective way to ensure data quality, patient safety and trial integrity. Statistical methods are used to highlight errors and omissions, detect outliers, check for low variance to identify unusual correlations that may suggest scientific misconduct or improper data collection. By identifying which trial sites require on-site monitoring and source data verification, support can be focused where it is most needed, reducing the environmental impact and cost of travel.

Trial management

Our trial management teams have knowledge of every stage of the clinical trial life cycle from setup, planning and implementation through to reporting.  

Expert trial managers with the training and experience to overcome operational challenges and technical complexities are often the difference between the success and failure of a clinical trial. Our professional trial staff contribute to UK Clinical Research Collaboration working groups and other networks to advance clinical trial management practice. 

Our trial management expertise includes:

  • protocol development
  • funding applications
  • setup of oversight bodies
  • ethics committee, regulatory and NHS Trust research and development applications
  • trial management and coordination
  • good clinical practice (GCP) training
  • participant recruitment
  • quality control procedures
  • case report forms (CRFs)
  • database design, development and management
  • data management
  • design and management of trial websites.
Data management and IT

Our data managers provide the expertise, services and infrastructure to assist with data management needs throughout a trial, from design and setup through to data review and analysis. We have experience of data management for small, single-site studies through to large-scale, multi-centre randomised trials with up to 30,000 participants. Our data managers are experienced in using Electronic Data Capture Systems such as REDCap and in the design and validation of bespoke systems. 

We also have IT systems infrastructure and software development experts who design and maintain our databases and IT infrastructure and ensure that we meet the highest regulatory standards for data privacy and security. 

Our data management and IT specialists are experts in:

  • case report form (CRF) development and design
  • creation of Data Management Plans and Standard Operating Procedures
  • advice on data collection methods and data flow, including secure transmission of data
  • database design and specifications; including for the development of data capture, randomisation and unblinding systems
  • ensuring a high quality of computer systems validation to deliver a fully regulatory compliant database
  • data review and cleaning
  • management of pharmacovigilance data
  • reporting for interim and final data analyses
  • database development
  • IT systems infrastructure oversight.
Patient and Public Involvement 

Patients and the public are at the centre of our work and are involved at every stage in the research process, from development of research ideas to communication of trial results.

The involvement of patients and the public in the early stages of trial development, to identify questions and outcomes important and relevant to them, is a key part of our approach to Patient and Public Involvement (PPI). We involve PPI in designing robust and relevant clinical trials, as co-applicants on the grants.

We include PPI representatives on management group and trial steering committees and include them in decision- making about the conduct of trials and the trial protocol, ensuring that a patient and public voice is heard throughout the timeline of our trials.

We are committed to enrolling a representative and diverse population, and high-quality PPI work has been and will continue to be central to our work to achieve that goal.

We involve patients and the public in the writing and dissemination of trial results, both to clinicians and to the public.

Equity and inclusion

We have developed and evaluated new effective methods to increase recruitment and follow up. We use approaches to ensure trial populations reflect the gender, social and ethnic diversity of populations they are recruited from, so there is equal opportunity to benefit from research. When we develop interventions, we do so with input from diverse social and ethnic groups to ensure interventions are relevant and acceptable to those with greatest health need. 

Environmental impact

Clinical trials are energy intensive and produce substantial greenhouse gas emissions. We need to establish awareness about the broader consequences of health care and research, and through awareness increase the pace of action to mitigate one of the most important global challenges of our time. This remains an area of interest to our CTU and to LSHTM more widely.

Final results of TB-PRACTECAL published

The final results of TB-PRACTECAL have been published in The Lancet Respiratory Medicine:


TB PRACTECAL is a phase 2/3 multicentre, randomised, controlled clinical trial to find short, tolerable and effective treatments for people with drug-resistant tuberculosis (DR-TB). The trial evaluated the efficacy and safety of three 24-week, all-oral regimens for the treatment of rifampin-resistant TB. These results confirm the interim results published in the New England Journal of Medicine in 2022:

New study shows anaemia can hinder blood clotting and may reduce effectiveness of tranexamic acid

A paper published in the Journal of Thrombosis and Haemostasis, by researchers from Semmelweis University in Hungary and the CTU reveals that anaemia can hinder blood clotting and potentially make tranexamic acid (TXA), a drug used to prevent postpartum haemorrhage (PPH) in women, less effective.

This study was conducted to determine the separate and combined role of TXA and red blood cells in the inhibition of fibrinolysis. Read the publication: 

The WOMAN-2 trial is assessing whether giving TXA can prevent PPH in women with moderate and severe anaemia. The results of this trial are expected in 2024.

Additional analyses from REVIVED-BCIS2 published

Important new results and health economic analysis from REVIVED-BCIS2 have been published.

A secondary analysis was published in JAMA cardiology:

These results were presented at the American College of Cardiology conference (ACC 2023) and revealed that percutaneous coronary intervention (PCI) remained ineffective, regardless of the extent of viability. In addition, the analysis showed that measuring scar burden is major predictor of events and left ventricular recovery.

A health economic analysis of data from REVIVED-BCIS2 was published in AHA Journals:

These results were presented at the American Heart Association conference (AHA 2023). This analysis showed that PCI was associated with minimal difference in QALYs and considerable incremental cost and that a strategy of PCI for ischemic left ventricular systolic dysfunction (ILVD) is not a justifiable use of healthcare resource.

Safetxt trial qualitative results published

The qualitative results of the Safetxt trial have been published in BMJ open: A qualitative study exploring experiences of the safetxt digital health intervention to reduce sexually transmitted infections in young people in the UK 

Safetxt was a single blind randomised controlled trial and a linked qualitative study to establish the effectiveness of a safer sex intervention delivered by mobile phone messaging on STI infection.

WOMAN-2 trial completes recruitment

The WOMAN-2 trial has achieved its target of recruiting 15,000 women randomised across sites in Nigeria, Pakistan, Tanzania and Zambia. 

The trial's aim is to see if giving tranexamic acid can prevent postpartum haemorrhage (PPH) and other severe outcomes in women with moderate and severe anaemia. Find out more about the trial.

ARREST trial results published

The ARREST trial, involving the London Ambulance Service and all hospitals in London, found there’s no difference in 30-day survival for out-of-hospital cardiac arrest (OHCA) patients who were taken by ambulance to a specialist cardiac arrest centre compared with those delivered to the geographically closest emergency department. The study also found no overall difference in brain and nerve function at discharge and no difference between the two groups in death rates after three months.

The results were presented at the European Society of Cardiology Congress and published in The Lancet:

The trial’s aim was to determine the best post-resuscitation care pathway for patients without ST-segment elevation (STE). The ARREST trial involved 862 patients recruited across London between 2018 and 2022.

New analysis on arrhythmia from REVIVED-BCIS2 trial

Further analysis from the REVIVED-BCIS2 trial shows:

  • Percutaneous coronary intervention (PCI) does not reduce death or aborted sudden death in ischemic left ventricular dysfunction
  • There’s no difference in the rate of implantable cardioverter defibrillator (ICD) therapies or sustained ventricular arrhythmias

Read the recent publication: Arrhythmia and Death Following Percutaneous Revascularization in Ischemic Left Ventricular Dysfunction: Prespecified Analyses From the REVIVED-BCIS2 Trial

REVIVED-BCIS2 evaluated the efficacy and safety of PCI compared to optimal medical therapy (OMT) alone for ischaemic left ventricular dysfunction. Seven hundred patients were enrolled across 40 centres in the UK between August 2013 and March 2020.

WOMAN-2 trial results published

Evidence from the WOMAN-2 trial shows that pregnant women with anaemia are substantially more likely to suffer life-threatening bleeding after childbirth. These findings are published in the The Lancet Global Health:

For further information listen to this podcast of Prof Rizwana Chaudhri and Prof Ian Roberts discussing their research investigating the association between maternal anaemia and post-partum haemorrhage from The Lancet Global Health.

Watch this video on: How maternal anaemia causes severe bleeding in childbirth

The WOMAN-2 trial recruited 10, 620 women with anaemia from hospitals in Nigeria, Pakistan, Tanzania and Zambia between August 2019 and November 2022. WOMAN-2 examined the association between anaemia and the risk of postpartum haemorrhage (PPH). The trial looks at whether giving tranexamic acid can prevent PPH and other severe outcomes in women with moderate and severe anaemia.
