Secondary study designRandomised controlled trial
Study setting(s)Hospital
Study typeOther
Scientific title
Study acronymModafinil Study
Study objectivesTherefore we wish to examine brain activity and performance during hand/eye tracking manoeuvres, (as quantified by fMRI and our tracking tasks), in normal subjects before and after total sleep deprivation following treatment with Modafinil or placebo. We will compare whether the Modafinil has reversed the effects of the sleep deprivation, compared to placebo

Health condition(s) or problem(s) studiedN/A
InterventionPlease note that as of 16/09/09 the status of this trial has been changed to "Stopped" due to relocation of primary investigator (PI) and lack of funding.

Each subject will be scanned 3 times, the first as a baseline, after normal sleep, and then twice after sleep deprivation, following treatment with Modafinil or placebo, in random order. Within each scanning session the subject will perform a series of hand/eye tracking tests of varying difficulty in random order, and a global visual stimulation test. Following the scans objective sleepiness will be quantified from the OSLER test of subjective sleepiness and steering ability will be quantified from the Oxford Steering Simulator. Subjects will be pre-trained to stable performance on the tracking task prior to fMRI scanning.
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)Modafinil
Primary outcome measureThe primary endpoint of the trial is the difference in activation of the occipital visual cortex area responsible motion detection (V5/MT) during global visual stimulation after Modafinil and placebo
Secondary outcome measuresSleep latency (measured by the OSLER test), driving simulator performance and tracking error will be secondary endpoints
