Plain-language summary
This is a single-centre, open-label, non-randomised, single oral dose study in healthy male subjects. It is planned to enroll and dose 6 subjects. Subjects will be admitted to the clinical unit on the evening of Day 1 prior to investigational medicinal product (IMP) administration. Subjects will be dosed on the morning of Day 1 and it is planned that they will remain resident in the clinic until up to 168 hour after dosing (up to Day 8). It is planned that subjects will be released as a group when all subjects have achieved a mass balance cumulative recovery of \>90% or if \<1% of the dose administered has been collected in urine and faeces within 2 separate, consecutive 24 hour periods.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
• Body mass index of 18.0 to 35.0 kg/m2
Exclusion Criteria:
* Regular alcohol consumption \>21 units per week (1 unit = ½ pint beer, or a 25 mL shot of 40% spirit, 1.5 to 2 Units = 125 mL glass of wine, depending on type)
* Current smokers and those who have smoked within the last 12 months. A breath carbon monoxide reading of greater than 10 ppm at screening
* Radiation exposure, including that from the present study, excluding background radiation but including diagnostic x-rays and other medical exposures, exceeding 5 mSv in the last 12 months or 10 mSv in the last 5 years. No occupationally exposed worker, as defined in the Ionising Radiation Regulations 2017, shall participate in the study
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring

Mass balance recovery of total radioactivity in all excreta: amount excreted (Ae) and Ae as a percentage of the administered dose (%Ae), cumulative recovery (CumAe), and cumulative recovery expressed as a percentage of the administered dose (Cum%Ae)
