Background and study aims
The Sponsor is developing a new test medicine for the potential treatment of cognitive disorders (diseases which affect how the brain works), such as fragile X syndrome, a genetic disorder which may cause learning disabilities and cognitive impairment; and Alzheimer’s disease, which causes the brain to shrink and die and is characterised by cognitive decline (for example, confusion or memory loss). This healthy volunteer study is trying to identify how the test medicine is taken up, broken down and removed from the body. 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 is also being studied.
Who can participate?
Healthy male volunteers aged 30 to 65 years.
What does the study involve?
The study consists of one part, involving a single cohort of 6 volunteers. Volunteers receive a single oral dose of the radiolabelled test medicine [14C]-BPN14770 Oral Capsule in the fasted state. Volunteers enter the clinical unit on Day -1 (the day before their dose) and are discharged on Day 8 (168 hours after their dose) at the earliest. The residency could be extended up to Day 15 (336 hours after their dose). Volunteers’ blood, urine and faeces are taken throughout the study for analysis of the test medicine and for their safety. Volunteers are expected to be involved in this study for approximately 6 weeks from screening to discharge.
What are the possible risks and benefits of participating?
Participants get no medical benefit from taking part in the study. However, development of a treatment for Fragile X syndrome and Alzheimer’s disease may benefit the population as a whole. It is considered that the risk/benefit evaluation in this study supports the use of healthy volunteers. Full information on possible side effects is provided to volunteers in the Participant Information Sheet and Informed Consent Form. Volunteers are closely monitored during the study and safety assessments are performed regularly.
