When and how we cluster and cross over: methodological and ethical issues
Spence et al. describe the need for more randomized controlled trials to provide rigorous evidence of the real-world effectiveness of treatments and treatment strategies in anesthesia practice. This call is supported by evidence citing a large degree of individual practice variability among cardiac anesthesiologists regarding benzodiazepine use within the standard of care.1 They describe the cluster randomized crossover design as ideal for this purpose. In the proposed approach, they “seek to evaluate the impact of two different approaches to cardiac anesthesia, one where nearly all patients receive intraoperative benzodiazepines unless there are contraindications (routine benzodiazepine arm), and the other where nearly all patients receive no intraoperative benzodiazepines unless there are contraindications (benzodiazepine restricted arm)…during 12, four-week crossover periods”.1 The interventions are implemented as policies such that all eligible patients in the hospital during each period receive the allocated interventions by default without any patient recruitment or consent. While we do not dispute the need for rigorous evidence to inform policy and practice, we have concerns regarding the methodological and ethical issues raised in trials such as the B-Free trial.

Improving Retention in Clinical trials: Retention strategies, Research Priorities and Useful Resources
Anna Kearney is a Trials Methodology researcher within the Clinical Trials Research Centre at the University of Liverpool. Over the last 6 years she has undertaken a number of methodological research projects, predominantly investigating the recruitment and retention of participants in Clinical Trials. At present she is coordinating a team of over 20 reviewers from across five nations as part of the ORRCA/ ORRCA2 project. ORRCA (www.orrca.org.uk) is a free, online, searchable, resource aimed at helping trial teams and methodologists navigate literature on recruitment and identify effective recruitment strategies relevant to different types of trials. Thousands of articles are currently being reviewed in order to update the resource and to extend it to include retention research.

How to design a dose-finding study using the Continual Reassessment Method
Simon Bond, NIHR Cambridge Clinical Trials Unit, University of Cambridge
Graham Wheeler, Cancer Research UK & UCL Cancer Trials Centre
Christina Yap, The Institute of Cancer Research, London
The continual reassessment method (CRM) is a model-based design for phase I trials, which aims to find the maximum tolerated dose (MTD) of a new therapy. The CRM has been shown to be more accurate in targeting the MTD than traditional rule-based approaches such as the 3 + 3 design, which is used in most phase I trials. However, the CRM’s uptake in clinical research has been incredibly slow, putting trial participants, drug development and patients at risk.
We present a structured framework for designing a dose-finding study using the CRM. We provide recommendations for key design parameters, advice on conducting pre-trial simulation work to tailor the trial’s design, and guidance on how to conduct and report dose-finding studies using the CRM. We also run through an example case-study where the CRM has been applied in practice. Our associated paper (Wheeler et al., 2019; BMC Med Res Methodol) also provides practical tools to support clinicians and statisticians, including software recommendations, and template text and tables that can be edited and inserted into a trial protocol.
Lastly, we will present dtp-crm, a newly developed interactive web application that can be used to design and conduct a CRM through a useful visual tool, Dose Transition Pathways (Yap et al., 2017; Clinical Cancer Research).

Katie Gillies, University of Aberdeen
Trial retention: priorities for research and participant centred evidence.
This webinar will present the PRIORITY II project which is a James Lind Alliance priority setting process that identified the Top10 research questions for trial retention. Katie will then present findings from projects focusing on understanding participant perspectives in relation to trial retention and set these in ongoing work to develop participant centred retention interventions.
A recording of this webinar will be uploaded soon.

Shaun Treweek, University of Aberdeen
Too much of a good thing? Are we collecting more data than we need?
Trials clearly need data but can we have too much, or at least more than we need? This webinar will highlight the potential for weighing trials down with more data than are needed. It will lean on Trial Forge work in a project called DataCat as well as outline a new project called ORINOCO that looks at the amount of time spent collecting outcome data.
A recording of this webinar will be uploaded soon.
Clare Clement, University of Bristol
Trials rarely recruit well or complete on time and one contributory factor is clinician engagement. This situation is often worse in surgical trials, where treatment preference is strong and research-active senior surgeons are rare. Trainee Research Collaboratives (TRCs) have recently been set up in the UK and have successfully conducted large, multi-centre surgical trials.
We conducted a study to understand the key elements of success within the TRCs and their trials and developed strategies for enhancing trainee engagement in research. This webinar will discuss the motivations of trainees to engage in research, the challenges they face and how these have been overcome. It will outline five key strategies to enhance engagement and contribute to trials being delivered on time and target.
Ashma Krishan, University of Liverpool
The most commonly used approaches for the analysis of time-to-event (TTE) outcomes impose an assumption of proportional hazards (PH). Methods are available for assessing the validity of the PH assumption, however, the assumption is not always checked or reported for validity. The webinar will focus on the results from a recent review of systematic reviews which was conducted to understand the methodology used for analysing TTE outcomes and how often the PH assumption is assessed.
29 January, Sharon Love and Vicki Yorke-Edwards, UCL
In 2013 the FDA and EME suggested risk-based monitoring was acceptable and ICH concurred in 2016. There have been a handful of studies showing that risk-based monitoring is acceptable, that triggers are useful and that maybe on-site SDV is not necessary. However there has been little guidance on how we should carry out central monitoring or on-site monitoring. We will give the results of a survey which aimed to find out how UKCRC registered CTU in the UK carry out monitoring for phase III CTIMPs.
