xen-d0103 ...Study Participants
87This study is an evaluation of the safety and tolerability of XEN-D0103 in healthy subjects. Part 1 assesses the safety, tolerability and blood levels of the ascending single doses of XEN-D0103. Blood levels of XEN-D0103 will be assessed when administered with food and also without food in Part 2. The safety, tolerability and blood levels of XEN-D0103 will be assessed following dosing for 10 days in Part 3.
8 subjects (6 receiving 10mg XEN-D0103, 2 receiving placebo)
8 subjects (6 receiving 30mg XEN-D0103, 2 receiving placebo)
8 subjects (6 receiving 60mg XEN-D0103, 2 receiving placebo)
8 subjects (6 receiving 120mg XEN-D0103, 2 receiving placebo)
8 subjects (6 receiving 200mg XEN-D0103, 2 receiving placebo)
17 subjects receiving 200mg XEN-D0103 with either a high fat meal or following an overnight fast.
10 subjects (8 receiving 30mg XEN-D0103 twice daily, 2 receiving placebo twice daily)
10 subjects (8 receiving 60mg XEN-D0103 twice daily, 2 receiving placebo twice daily)
10 subjects (8 receiving 150mg XEN-D0103 once daily, 2 receiving placebo once daily)
