At the start of October, lots of the Unit’s clinical trials methodology researchers travelled to Edinburgh, for the 7th International Clinical Trials Methodology Conference (ICTMC). ICTMC is the largest academic-led conference on clinical trials, bringing together trialists from across the globe to present their latest work in trials methodology. This year's conference featured a wide variety of workshops, talks and poster presentations from MRC Clinical Trials Unit researchers. I

n this latest episode of the Trial Talk podcast, four of the Unit’s early career researchers discuss the work they presented at ICTMC 2024. Gideon Darko Asamoah tells us how he will deliver a core outcome set for trials in severe malaria; Jingyi Xuan describes her project addressing intercurrent events in platform trials; Dongquan Bi discusses the effects of different cluster sizes in cluster trials; and finally, Kate Roberts explains how she aims to improve the wording around consent for accessing trial participants' healthcare records.

In September 2024, the World Health Organization (WHO) released new guidance on preventative treatment for tuberculosis (TB). Thanks to new evidence from two randomised controlled clinical trials, the WHO now recommends that contacts of people with multidrug-resistant TB take six months of daily levofloxacin. In this episode of the Trial Talk podcast, we find out more about the TB-CHAMP and VQUIN trials. We also learn how the teams came together to combine their data and strengthen their evidence, using new statistical methodologies developed at the MRC Clinical Trials Unit at UCL. The episode features interviews with Anneke Hesseling, Principal Investigator for TB-CHAMP, based at Stellenbosch University, and Trinh Duong, based at the MRC CTU at UCL, the trial statistician for TB-CHAMP and lead for the combined data analysis with VQUIN.

Optimisation immunotherapy clinical trials investigate ways of reducing the intensity of immunotherapy cancer treatment. This could be beneficial for patients’ quality of life. But these trials can be challenging to run, as patients may be concerned about the impact that reducing the intensity of treatment could have on the cancer.

This episode of the Trial Talk podcast focuses on the MRC Clinical Trials Unit at UCL’s OPTIC study, which explores how people with cancer feel about taking part in optimisation immunotherapy trials. Clinical Fellow Sophie Merrick discusses the main barriers that patients face and recommendations to address them.

The MRC Clinical Trials Unit at UCL is committed to actively involving patients and the public in our trials. All our Patient and Public Involvement (PPI) work is overseen by our PPI Group, made up of MRC CTU staff alongside seven patient representatives, with a wide range of experience in different areas. In this episode of the Trial Talk podcast, two members of the Unit’s PPI Group, Richard Stephens and Ian Newsome, discuss what PPI means to them; how they got involved as patient representatives in clinical research; and how the MRC CTU at UCL embeds PPI into our trials.

An estimand is a description of the research question a trial seeks to answer, which can help researchers better understand how their study should be designed and analysed. Estimands also provide a clear way to communicate treatment effects to different stakeholders. This episode of the Trial Talk podcast features Principal Research Fellow Brennan Kahan, exploring how triallists could benefit from using estimands. Brennan also discusses his recent paper which aims to demystify new guidance on the use of estimands.

Clinical trial results usually tell us how effective a treatment was on average for the overall group of participants, but a key question for clinicians, patients and policy makers is: which individual patients benefit most from the treatment and which don’t benefit as much? In the latest episode of the Trial Talk podcast, Peter Godolphin and David Fisher discuss a new method for determining how treatment effects differ between subgroups of patients across multiple clinical trials, as well as how other meta-analysis researchers can use it.

UKCTOCS (UK Collaborative Trial of Ovarian Cancer Screening) is one of the largest screening trials in ovarian cancer. More than 200,000 women from England, Wales and Northern Ireland took part in it, and it ran for almost two decades. Designing and running such a large and lengthy trial came with its own challenges. In this episode, Professor Usha Menon discusses the key challenges that UKCTOCS faced in its design, conduct an analysis, and how the team addressed them.

Further information is available on the UKCTOCS website at ukctocs.mrcctu.ucl.ac.uk

In the first episode of our new Trial Talk series, Hanif Esmail and Conor Tweed take over the microphones to interview Andrew Nunn and Sarah Meredith, who have both recently retired from the Unit, having spent a combined total of 92 years working in the field of tuberculosis (TB). As we celebrate Andrew and Sarah’s long and accomplished careers, we’ll dive into the history of TB clinical trials and muse on the future of TB research.
