Clinical trials of investigational medicinal products (CTIMPs)

Under the EU Clinical Trials Directive 2001/20/EC and the Medicines for Human Use (Clinical Trials) Regulations 2004, which transposed the Directive into UK law, any CTIMP conducted in the UK requires both clinical trial authorisation (CTA) from the Medicines and Healthcare products Regulatory Agency (MHRA) and a favourable opinion from an ethics committee.

 The MHRA is responsible for advising on the Regulations and requirements for CTA. Detailed guidance is available on the MHRA website. Section 2 of this guidance links to an algorithm to help you decide whether or not your research is a CTIMP. The page also contains contact details if you remain unsure after checking the algorithm.

 

Applications to MHRA for CTA can be prepared using IRAS.  Alternatively, applicants may enter the data required for the application using the EudraCT website.

 

Applications for CTA may be made either in parallel or in sequence with the application for ethical review. A EudraCT number must be obtained from the EudraCT website and included with both applications.
