Accessibility statement


PROMETHEUS is a major national programme of research funded by the Medical Research Council (MRC) to facilitate the routine embedding of a methodology research study within a planned or ongoing trial. This uses Studies Within A Trial (SWAT) methodology to build the evidence base on participant recruitment and retention in trials. PROMETHEUS aims to pump prime at least 25 host trial teams up to £5000 to undertake SWATs of participant recruitment or retention strategies, and is currently inviting applicants for funding.

How to apply for a PROMETHEUS award

Further information about PROMETHEUS and how to apply for an award can be found in the Host Trial Information Leaflet (PDF , 1,070kb). Applications from trial teams who wish to undertake SWATs are currently being taken. If you are interested in applying for a PROMETHEUS award please complete the Host Trial Expression of Interest Form (MS Word , 87kb).

Please note that PROMETHEUS aims to fund existing trial teams only. Teams wishing to submit a SWAT as part of a brand new funding application to the NIHR should consider applying to the NIHR SWAT programme. If this is the case we would be happy to help you build a SWAT into your new proposal.
