Register your interest

This form puts you on our volunteer registry. It is not consent, it is not an application, and it does not commit you to anything at all — it simply lets us contact you if a study opens that might suit.

Step 01

You register

A few details about you and your health. Five minutes at most.

Step 02

We match

We check your details against studies currently open at your nearest site.

Step 03

We call you

A short pre-screening conversation. You can say no at this point, or any point after.

Step 04

You decide

If it looks right, we invite you in to talk it through properly before anything is signed.

About you


About your health

Please keep this brief and general. Do not send detailed medical records or test results through this form — if we need them, we will arrange a secure route.


Consent to contact

Your information is handled under UK GDPR (UK residents) or HIPAA (US residents) and stored in the region it was collected. Read our privacy policy for the full detail. We never sell or share registry data with third parties for marketing.

Before you ask

Registering is not agreeing

You are not consenting

Informed consent is a separate, formal process that happens in person, with an investigator, after you have had the information sheet to take home.

You may not be eligible

Most people who register are not suitable for any given study. That is normal and it is not a judgement about your health.

You can leave whenever

One email removes you from the registry. If you have already joined a study, you can withdraw from that too, without giving a reason.
