  • Research summary

    The Sponsor is developing the test medicine, COMP360, for the potential treatment of treatment-resistant depression. Depression is a common mental health problem that can cause people to experience low mood, loss of motivation or pleasure, feelings of guilt or low self-worth, disturbed sleep, changes in appetite, low energy and concentration. Patients with treatment-resistant depression see no improvement in their symptoms with standard depression medication.

    In this study, we’ll give healthy volunteers a single dose of test medicine to find out how the body breaks down and gets rid of the test medicine. The test medicine will be ‘radiolabelled’ - it will contain a small amount of radioactivity (Carbon-14) - so that we can track it in the body.

    In this study in healthy volunteers, we aim to answer these questions.
    • Does the test medicine cause any important side effects?
    • How much test medicine enters the bloodstream and how quickly does the body get rid of it?

    This study will take place at one non-NHS site in Nottingham.

    We plan to enrol 6 healthy men aged 30-55 years.

    Volunteers will receive a single dose of radiolabelled test medicine, as a capsule by mouth. They’ll stay in the clinic for up to 10 nights and take up to 5 weeks to finish the study.

    We’ll collect blood and urine samples to do safety tests. Over a period of at least 8 days, we’ll take many blood samples and volunteers will collect all their urine and faeces so that we can measure the amount of test medicine and its breakdown products.
