Clinical trial summary

We are conducting a clinical trial for an experimental drug that could be used to treat people with alcohol addiction and to better understand the disease and the associated health problems.

In this clinical trial, we are recruiting approximately 60 healthy participants aged 18 to 45.

We will observe if the experimental drug is safe, how long it stays in your blood and how it affects your heart activity.

If you are interested in participating in the trial:-

  • You will need to attend a screening appointment so we can check if you are suitable to take part in the trial. At this appointment, we you will undergo assessments including but not limited to taking blood, check your heart and carry out a physical examination.
  • If results from your screening appointment show you are suitable for the trial, you will be invited to take part.
  • This will involve an in-house stay of 13 days / 12 nights in our clinical research unit.
  • After your stay with us you will be required to return for a follow-up visit 3 to 7 days after discharge from the in-house stay. This means the whole process takes up to 54 days from your screening visit through to your final visit.
  • In total, if you are included in the clinical trial you will come to the research unit 3 times.
  • During your stay with us you will receive multiple doses of the experimental drug as oral capsules (e.g. via the mouth) and we will conduct a number of assessments (like those we did at screening) to check how safe the experimental drug is, to help us understand how long it takes for your body to process the experimental drug and to check how the experimental drug affects your heart.

Unbelievable service! They looked after me so well, and I would recommend them to anyone interested in participating in a clinical trial. I want to thank all the staff at trials4us for their continued efforts and for looking after me so well.


Very impressive. Thank you for taking care of me and for the valuable service you offer.


Very professional environment in the heart of London to conduct studies that help discover the medicines of the future.


The initial process to get accepted on the trials was easy, and the payment was prompt and precise. The staff here at the clinic are lovely, very professional, helpful, and understanding.
