Nottingham Clinical Trials Unit Criteria for engagement The Nottingham Clinical Trials Unit (NCTU) aims to conduct clinically important high quality randomised trials that improve health and wellbeing. Clinicians and researchers wishing to engage with NCTU are advised to contact us early in their planning. The success and value of NCTU depends on the quality and relevance of the trials conducted. The selection of new trials at NCTU is based on the following criteria: Addresses an important question The proposed trial must address a clinically important question. For example, if the trial is successful, there is a reasonable expectation that the results would lead to a worthwhile change in clinical practice or public health policy. Identified gap in our knowledge An appropriate high quality systematic review supports the need for a trial. Feasibility There should be a well thought through strategy for demonstrating that it is feasible to recruit and retain participants into the trial. The assumptions behind the study projections should be supported by evidence that they are realistic. If this evidence is not available, it should be sought from a pilot study or early returns as the study commences. The study should be led by a Chief Investigator with the correct blend of experience and clinical credibility. Methodologically sound NCTU engages with leads of individual trials at the planning stage to ensure the optimal scientific design, with the best and most appropriate analysis and suitable methods of managing and conducting the trial. Appropriate research team Project team has an appropriate skill mix, and there is clear agreement about the role of NCTU. Potential to secure funding There should be identified potential sources of funding. For example, based on identified priorities for the NHS, a topical issue, or a commissioned or themed call. Financially viable NCTUs involvement in the study must be appropriately financed, with a minimum expectation that NCTU recovers the true cost of its engagement in the study. Attractive to NCTU NCTU will assess its engagement in a trial based on the expectation that the trial should enhance NCTU’s reputation for delivering high quality, clinically relevant and methodologically excellent or innovative trials. Factors that will be considered include: o Would the trial results contribute to significant change in the clinical management of a condition o Does it add coherence to the NCTU portfolio, does it fit within our existing themes o Would the proposal enhance the strategic plan of the School of Medicine, for example is it in a clinical area recognised to be a local strength o Are there opportunities to explore methodological advances in the design and conduct of clinical trials
