There are about 1129 clinical studies being (or have been) conducted in Estonia. 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.
The primary objective of this study is to evaluate the long-term safety profile of BG00012 (dimethyl fumarate). Secondary objectives of this study are to evaluate the long-term efficacy of BG00012 using clinical endpoints and disability progression, to evaluate further the long-term effects of BG00012 on multiple sclerosis (MS) brain lesions on magnetic resonance imaging (MRI) scans in participants who had MRI scans as part of Studies 109MS301 (NCT00420212) and 109MS302 (NCT00451451) and to evaluate the long-term effects of BG00012 on health economics assessments and the visual function test.
The main goal is to provide additional information to the risk-benefit assessment of the drug.
Primary objective : - To demonstrate the antidepressant efficacy on the Hamilton Depression Rating Scale of SR58611A 700mg/day compared with placebo in the treatment of patients with a recurrent major depressive episode. Secondary objectives: - To assess the safety profile of SR58611A 700 mg/d in comparison to placebo and to assess plasma concentrations of the active metabolite.
Study hypothesis: supplementary magnesium may influence the blood calcium level in treated hypoparathyroid patients. Patients will be treated with supplementary magnesium (350 mg/day) for 3 weeks. Calcium and other relevant blood parameters will be measured before the treatment, at the end of treatment and 2 weeks after stopping treatment.
REFLEXION is a double blind extension of the study 27025 (NCT00404352) (REFLEX). The purpose of the study is to obtain long-term follow-up data in subjects with clinically definite multiple sclerosis (MS) and subjects with a first demyelinating event at high risk of converting to MS, treated with fetal bovine serum [FBS]-free/human serum albumin [HSA]-free formulation of interferon [IFN]-beta-1a (RNF).
The purpose of the study is long-term safety, tolerability and efficacy of nalmefene in patients with alcohol dependence.
This 2 arm study will compare 2 treatment strategies based on tocilizumab in combination with methotrexate or placebo in patients with moderate to severe rheumatoid arthritis. Patients receiving methotrexate treatment will be randomized to receive either a) tocilizumab 8 mg intravenous (iv) every 4 weeks + methotrexate orally (po) weekly or b) tocilizumab 8 mg iv every 4 weeks + placebo po weekly. After the first 24 weeks of blinded treatment, treatment adjustments (increase or decrease of treatment intensity) may be introduced at intervals, based on response. The anticipated time on study treatment is up to 3 years, and the target sample size is approximately 470 patients.
The primary objective of this study is to document the long-term safety and tolerability of teriflunomide in Multiple Sclerosis (MS) patients with relapse. The secondary objective is to document the long-term efficacy on disability progression, relapse rate and Magnetic Resonance Imaging (MRI) parameters.
In this study information is gathered about the treatment of Parkinson patients who present themselves in a neurological practice for the first time
The purpose of the study is to test whether vaccinations with CYT003-QbG10 can improve allergy symptoms in patients with house dust mite allergy. The active treatment will be compared against placebo.
