Double-blind Design clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Neurostimulation in Chronic and Episodic Migraine

Start date: October 1, 2016
Phase: N/A
Study type: Interventional

Currently, successful prevention of migraine is not sufficiently achieved by (prophylactic) drug therapy. In contrast, neurophysiologically guided treatments might provide an alternative avenue, since these can normalize brain alterations without side effects. Transcranial direct current stimulation (tDCS) appears useful in the acute and prophylactic treatment of migraine, probably because of its modifying and re-balancing influence on neuronal activity. Yet, to test for the efficacy of tDCS in a clinically acceptable way, it is necessary to apply not only tDCS but also a "sham" placebo, which is often neglected in tDCS stimulation studies. Further, tDCS needs to be applied in a large (n > 20) sample of well-defined migraine patients, which would be advantageous, compared to previously published work. Monitoring sources of regional neuronal alterations in migraineurs prior and after tDCS is essential to investigate physiological mechanisms of tDCS. There is an increasing interest towards non-pharmacological treatment alternatives for migraine (and headache disorders) with reduced side effects to established prophylactic medications. The primary outcome of this project is to demonstrate that repetitive sessions of neurostimulation lead to a significant and permanent reduction of the primary symptom severity (i.e. migraine attacks) for patients suffering from chronic and episodic migraine. Since neurostimulation tools are nowadays accepted as therapeutic tools, our study might provide evidence that tDCS can be a non-pharmacological alternative for treating migraine.
