Healthy Male Volunteers | Safety, Tolerability, Pharmacokinetics and Effects on Transcranial Magnetic Stimulation of Oral Doses of XEN1101

Healthy Male Volunteers research study

What is the primary objective of this study?

The XEN1101 Phase 1 clinical trial is a randomized, double-blind, placebo-controlled study that will eventuate the safety, tolerability, pharmacokinetics (PK) and effects on transcranial magnetic stimulation (TMS) of oral doses of XEN1101 in healthy male subjects.The TMS procedure is designed to demonstrate delivery of XEN1101 into the central nervous system and to observe a change in cortical excitability as measured by EEG and/or EMG activity. It is estimated there will be approximately 15 subjects in the planned study.
