- Lead Sponsor
- AstraZeneca
- Brief Summary
A study to investigate how the body breaks down and gets rid of the test medicine, AZD5462.
To help investigate this, the test medicine is radiolabelled, which means that the test medicine has a radioactive component (carbon-14), which helps us to track where the test medicine is in the body. The safety and tolerability of the test medicine will also be studied.
- Detailed Description
This is an open-label, two-period study designed to assess the mass balance recovery, absorption, metabolism, excretion of \[14C\]AZD5462 and the absolute bioavailability of AZD5462 in healthy male participants.
The study will take place at 1 site in Nottingham, and enrol 8 healthy men aged 30-65 years. The study will include 2 Periods:
* In Period 1 volunteers will receive a single dose of radiolabelled test medicine as a liquid by mouth.
* In Period 2 volunteers will receive a single dose of the test medicine as capsules by mouth and shortly afterwards, a very tiny dose of radiolabelled study medicine by injection into a vein.
The participants will be resident in the clinical unit throughout both study periods for a total of 12 nights. The total study duration is approximately up to 6 weeks.
