Legal Representation

Clinical trials conducted in the UK by sponsors based outside the UK and EU require a legal representative established in the UK. This representative takes on defined regulatory responsibilities under the UK Clinical Trials Regulations, including being the named point of contact for the MHRA and accepting certain obligations in relation to trial oversight and regulatory compliance.

At Niche, we act as legal representative for international sponsors running studies in the UK, providing this service within the context of our broader clinical and regulatory expertise.

Compliance you can rely on. Partnership you can trust.

What We Do

We act as legal representative for sponsors based outside the UK who are conducting clinical trials under UK Clinical Trials Authorisation. This is a formal regulatory role that involves accepting defined responsibilities under the regulations and acting as the MHRA's point of contact for the sponsor. 

Our legal representative service is typically provided alongside our other clinical and regulatory support services, which means the sponsor benefits from a team that is already closely familiar with their programme and able to respond quickly and accurately to any regulatory enquiry.

How We Work

Before accepting the role of legal representative, we conduct a thorough review of the trial documentation and the sponsor's quality systems to ensure we are satisfied that the programme is being conducted in accordance with applicable regulations. We are not in a position to accept legal representative responsibilities for trials that we have serious concerns about. 

Once engaged, we maintain regular communication with the sponsor team and respond to MHRA enquiries on their behalf. We keep detailed records of all regulatory interactions and ensure that the sponsor is informed promptly of any communication that requires their attention or action.

Frequently Asked Questions
Any sponsor who is not established in the United KingdomUK or the European UnionEU is required to appoint a legal representative based in the UK before conducting a clinical trial under a UK Clinical Trials Authorisation.

This requirement exists under the UK Clinical Trials Regulations and reflects the need for a responsible party to be accessible to the MHRA and accountable for defined regulatory obligations within the UK jurisdiction.
The legal representative accepts certain regulatory responsibilities on behalf of the sponsor, including being the named point of contact for the MHRA, accepting service of documents and notices from the regulator, and taking responsibility for ensuring that the trial is conducted in accordance with the requirements of the authorisation and applicable regulations. 

The specific responsibilities are defined in the UK Clinical Trials Regulations.
We prefer to provide legal representative services within the context of a broader engagement with the sponsor's programme, because the responsibilities involved require a an in-depth understanding of the trial and confidence in how it is being conducted.

We consider each request individually and will discuss what level of wider involvement would be appropriate before agreeing to act as legal representative.
