There are about 2700 clinical studies being (or have been) conducted in Bulgaria. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This study will compare the change detected by a standardized rating scale (Hamilton Anxiety Rating Scale) scores in the active treatment group as compared to sham (placebo) group after 6 weeks of rTMS treatments. It is hoped that 6 weeks of rTMS treatment will lead to improvement of core symptoms in patients with GAD.

Parkinson's disease is a major neurodegenerative disorder in which there is a progressive loss of nigrostriatal dopaminergic neurons. The understanding that PD is a syndrome of dopamine (DA) deficiency led to the introduction in the clinical practice of L-dopa, a precursor of DA that crosses the blood brain barrier, and also to the use of selective inhibitors of MAO B, the major DA metabolising enzyme in man. This is a double-blind, placebo-controlled, parallel-group, randomised, multi-centre, multi national, Phase III trial, comparing two doses of safinamide (50 and 100 mg p.o. q.a.m.) versus placebo as add-on therapy to a stable dose of a single dopamine agonist in subjects with early idiopathic Parkinson's Disease. The principal efficacy measure, i.e., change in mean value of UPDRS - Section III total score from baseline to endpoint, was chosen based on regulatory guidance and prior use in other trials in similar populations.
The study aims to compare the effect of daily oral treatment of laquinimod capsules 0.6 milligrams (mg) with the effect of placebo capsules (capsules that contain no active medication) as well as with the effect of an existing Multiple Sclerosis (MS) injectable drug: Interferon β-1a (Avonex®).
