Treatment of Central Sleep Apnea Syndrome with low-pressure nasal continuous positive airway pressure and rebreathing.

Primary objective:To show that addition of dead space to low-pressure nCPAP (which is usually not effective but can be relatively well tolerated) makes the therapy effective and diminishes the apnea hypopnea index with >10/hour in patients…

To determine the mechanism of action of propranolol in the prophylactic treatment of migraine.

Varenicline, a partial nicotinic receptor agonist, for the treatment of excessive daytime sleepiness in Parkinson*s disease: a placebo-controlled cross-over study

This study is aimed to determine the efficacy of varenicline in reducing EDS in PD patients.

A randomized, double blind, double-dummy placebo controlled, 3-way cross-over study to determine the test-retest reliability of, and the effect of oral retigabine and riluzole on, peripheral motor nerve excitability measurements in patients with ALS.

Patients with ALS are routinely prescribed riluzole, the only registered drug for the treatment of ALS. This study will evaluate the concentration-effect relationship of riluzole (100 mg) and retigabine (300 mg) on axonal excitability measures. In…

Intra-subject variability in pain scoring and the consequences for analgesia treatment

In the current study we want to further explore the predictability of pre-treatment pain variability on the probability to experience pain relief. Knowledge on the understanding of individual differences in analgesic properties of a drug is of…

Randomized, double-blind, double-dummy, placebo-controlled, four-way crossover single dose
study to determine the test-retest reliability of, and the effect of oral valproic acid, levetiracetam and
lorazepam on, cortical excitability measurements in healthy volunteers as measured by TMS-EEG and TMS-EMG.

Primary Objective- To investigate the ability of TMS-EEG measures to detect effects on cortical excitability of valproic acid, levetiracetam and lorazepam in healthy subjects- To investigate the ability of TMS-EMG measures to detect effects on…

Bilateral vs. unilateral transcranial magnetic stimulation of the primary motor cortex to treat chronic orofacial pain: a pilot study with a randomized controlled design

In 2016, Henssen et al. discuss that orofacial pain may be conducted in a bilateral fashion, inducing activation of both thalami [1]. For this reason, bilateral stimulation of the motor cortex is thought to induce a stronger analgesic effect…

The primary objective of this study is to assess the efficacy of Ecopipam to reduce self-injurious behaviors (SIB) in adults and children with Lesch-Nyhan Disease (LND) in an outpatient setting. The secondary objectives of this study are to assess…

Interventional, randomised, double-blind, sequential-group, placebo-controlled single ascending dose study investigating the safety, tolerability, and pharmacokinetic properties of Lu AF34134 in healthy young men and healthy elderly men and women, and open-label, three-period crossover, food interaction study of Lu AF34134 in healthy elderly men and women.

- to examine the safety and tolerability of the research medication- to examine how the research medication is absorbed, broken down and excreted by the body.

A double blind, double dummy, randomized, placebo-controlled, 4 period cross-over study to examine the effect of PF-063782865 on evoked pain endpoints in healthy volunteers using pregabalin as a positive control

To investigate the ability of PF-06372865 to demonstrate analgesic properties in healthy subjects for pre-specified primary endpoints using a panel of pain tests.

Sumatriptan non-responders: evaluation of a possible biomarker

To find a simple test to explain non-responsiveness to sumatriptan in a proportion of patients with migraine.

Ephedrine as add-on therapy for patients with myasthenia gravis
