Study information

Primary study designInterventional
Study designrandomised, double blind, placebo controlled, crossover group study
Secondary study designRandomised controlled trial
Scientific title
Study objectives1. The effect of a single oral dose of L-000830982 versus oral placebo and an intravenous infusion of ethanol versus placebo on tremor over a 8-hour period in men and women with essential tremor will be estimated
2. The sensitivity and specificity of laboratory
tremography versus 2 ambulant tremography methods in classifying tremor movements versus other movements over a 8-hour period in men and women with essential tremor will be estimated
Ethics approval(s)Received from the local medical ethics committee
Health condition(s) or problem(s) studiedTremor
Intervention1. L-000830982 2.0 mg PO or placebo
2. EtOH, infused at a rate to maintain a plasma concentration of ~0.6 g/l (4 hours) or placebo IV
Intervention typeDrug
PhaseNot Specified
Drug / device / biological / vaccine name(s)L-000830982, ethanol
Primary outcome measure(s)

The sensitivity and specificity of Actiwatch and DynaPort MiniMod in discriminating tremor movements from other movements holding the clinical accelerometry/myography-based tremography as the gold standard.

Key secondary outcome measure(s)

1. Tremor intensity, measured by average acceleration amplitude (ìV)
2. Tremor duration measured by average duration of epochs classified as tremor (sec)
3. Tremor amount, measured by proportion of tremor movements per time unit (min/hour)
4. Tremor Clinical Rating Scale
