研究概览
简要总结
This is an open, two-part study in healthy male volunteers, aged 30-65 years.
This trial aims to understand how the human body absorbs, distributes, metabolizes and eliminates ontunisertib after a single oral dose of radiolabelled test medicine ([14C]ontunisertib) and determine the routes and rates of elimination of the test medicine.
详细描述
This is an open, two-part study in healthy male volunteers, aged 30-65 years with the trial duration of approximately 7 weeks.
In Part 1 of this study, healthy volunteers will be given a dose of test medicine orally followed by an intravenous injection of a very small dose of radiolabelled test medicine that contains a tiny amount of radioactivity (called carbon-14) so that the test medicine can be traced in the blood.
In Part 2, single doses of test medicine will be administered orally 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 it can be traced in the body.
Participants will take part in both study parts and will remain resident in the clinic for up to 10 days after their final dose of Investigation Medicinal Product (IMP). After the participants have left the clinic, they may have to collect their urine and faeces at home until mass balance criteria has been met.
Over a period of at least 8 days in Part 1 and 10 days in Part 2, many blood samples will be taken, and volunteers will collect all their urine and faeces so that the amount of test medicine and its breakdown products can be measured/analysed.
