It is important to design clinical trials to include all those who may benefit from the intervention being tested. Several frameworks have been developed to help researchers think about the barriers to inclusion of particular under-served groups when designing a trial, but there is a lack of practical guidance on how to implement these frameworks. This paper describes the ACCESS project, the findings from each phase of the project and the guidance we developed (STEP UP) on how to design more inclusive trials. Development of the STEP UP guidance had five phases: (1) Scoping literature review, (2) ‘roundtable’ discussion meetings, (3) redesign of trials, (4) interviews and (5) guidance document development, with input from public contributors and the ACCESS team. Over 40 experts contributed to the ACCESS project—patients and the public, clinicians, NHS research staff, trialists and other academics. The scoping review identified several strategies being used to improve inclusion, mostly around recruitment settings, but there was little evaluation of these strategies. The ‘roundtable’ discussions identified additional strategies being used across the UK and Ireland to improve inclusion, which were grouped into: Communication, Community engagement, Recruitment sites, Patient information, Flexibility, Recruitment settings, Consent process, Monitoring, Training for researchers and Incentives. These strategies were used to redesign three existing trials by applying one of the three INCLUDE frameworks (ethnicity, socioeconomic disadvantage, impaired capacity to consent) to one trial each, to produce the key recommendations for the guidance. Issues around implementation were explored in stakeholder interviews and key facilitators were identified: funders requesting information on inclusion, having the time and funding to implement strategies, dedicated staff, flexibility in trial protocols, and considering inclusion of under-served groups at the design stages. The STEP UP guidance is freely available at http://step-up-clinical-trials.co.uk . Researchers should consider inclusivity to shape initial trial design decisions. Trial teams and funders need to ensure that trials are given both the resources and time needed to implement the STEP UP guidance and increase the opportunities to recruit a diverse population. Randomised clinical trials compare one or more treatments to another to see which ones work best. Trials don’t always include people or groups who might benefit from the results: those excluded are sometimes called ‘under- served groups’. Recent work has shone a light on this and now researchers are being asked by the public, trial funders and others to design their research so that under-served groups are more able to take part. We worked on a project to find out how to make sure everyone can be part of clinical trials. We looked at published work and held five online meetings with researchers, doctors, and patients to see what was being done already, and to think of other things that could help under-served groups take part in trials. Three groups of people, including scientists, patients, doctors and other NHS workers then  used this information to redesign three older trials using some existing inclusivity frameworks to think through the barriers for under-served groups in these trials. The three groups then talked through these trials at a 2-hour meeting, suggesting changes to the original trial plan, and discussed whether the suggestions were practical and useful. From this we came up with recommendations for how to design trials so that they have fewer barriers for under-served groups. We interviewed people to find out the best way to put these things into practice and talk through any practical issues. Using all of this information: the recommendations and what came out of the interviews, the study team created some guidance – ‘STEP UP (Strategies for Trialists to promote Equal Participation in clinical trials for Under-served Populations)’ – for people working in trials.
