About this site

The Clinical Trials Toolkit was initially developed and launched in 2004 by the MRC and the Department of Health and Social Care to help clinical trialists and R&D managers understand the regulations and requirements for conducting trials. As the lead organisation for funding clinical trials, the NIHR has now taken over responsibility for the Clinical Trials Toolkit.

The new current version of the site was launched in late 2012. This was developed by the NIHR, in close collaboration with the Medicines and Healthcare products Regulatory Agency (MHRA), Health Research Authority (HRA), Medical Research Council (MRC) and other UK Clinical Research Collaboration (UKCRC) partners and stakeholders.

The site addresses the requirements of the current UK regulations. In the UK, the Medicines and Healthcare products Regulatory Agency (MHRA), protects and promotes public health and patient safety by ensuring that medicines, healthcare products and medical equipment meet appropriate standards of safety, quality, performance and effectiveness, and are used safely. If you remain unsure about how to ensure your trial meets the regulatory requirements, please contact the MHRA directly, using the contact details below:
