At the end of your study you must submit the following documents to the REC and to the Research Governance Team (also to the MHRA for CTIMPS):
You will then need to archive your study documents and data. This should include the data you have collected and any tools or documents needed to reproduce the study results from those data. It should be possible for someone looking at your archived material to reconstruct what you did on the study in detail and validate your results. For clinical trials please refer to the University's Archiving SOP.
You need to ensure that these are secured for 10 years, in line with the University policies (or 25 years for regulated trials such as CTIMPs or studies using Human Tissue for Human Application).
