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 purpose of this study is to compare the long-term efficacy and safety of desvenlafaxine succinate sustained release versus placebo in adults with Major Depressive Disorder, using a randomized withdrawal design. Randomized withdrawal means that after receiving desvenlafaxine succinate sustained release for a predetermined period of time, subjects will be selected by chance to either continue receiving the study drug or to be withdrawn from the study drug and receive placebo for the remainder of their participation in the trial. Subjects will not know to which group they have been assigned. The study consists of an up to 14-day screening period followed by an 8-week open-label period in which subjects will knowingly receive 50 mg/day of desvenlafaxine succinate sustained release. Subjects who do not respond to treatment, demonstrating no significant change in their depressive symptoms, will be withdrawn from participation at the end of this period. Responding subjects will receive an additional 3 months of open-label desvenlafaxine succinate sustained release at the same dose. Subjects with stable response to treatment at the conclusion of this 3 month period will be randomized to either desvenlafaxine succinate sustained release at 50 mg/day or placebo in a blinded manner for an additional 6 months or until symptoms of depression return. Following discontinuation at any point after enrollment in the study, subjects will receive two weeks of follow-up monitoring, including one week of blinded taper with 25 mg/day of desvenlafaxine succinate sustained release treatment for any subjects who have been taking desvenlafaxine succinate sustained release prior to discontinuation. Subjects assigned to placebo will receive a blinded placebo taper. Following taper, subjects will be evaluated for one additional week to monitor safety.
The trial randomise patients with asymptomatic carotid artery narrowing in whom prompt physical intervention is thought to be needed, but there there is still substantial uncertainty shared by patient and doctor about whether surgery or stenting is the more appropriate choice. The study is looking at immediate risks (within one month)and at long term benefits
The objective of the current study is to investigate the safety and efficacy of BI 10773 in 2 different doses compared to Metformin or to Sitagliptin given for 78 weeks in different modalities of treatment in patients with type 2 diabetes mellitus.
This study examines the efficacy of three doses of IPX066 as compared to placebo in Parkinson's disease.
To obtain additional safety data in subjects who have previously completed the MBP8298-01 study "A Double Blind Placebo Controlled Multi-Centre to Evaluate the Efficacy and Safety of MBP8298 in Subjects with Secondary Multiple Sclerosis" Dirucotide is generic name for MBP8298.
The purpose of this study is to determine whether MBP8298 is effective and safe in the treatment secondary progressive multiple sclerosis. Dirucotide is generic name for MBP8298.
Objectives: - To find out if the chance of developing a serious illness or of getting AIDS is less if patients start taking HIV medicines at a time when their cluster-of-differentiation-4 (CD4)+ cell count is still fairly high, instead of waiting until the CD4+ count is at the level where there is good evidence for starting medicines. - To learn more about how a strategy of starting HIV medicines early might affect other aspects of care, such as the chances of developing other illnesses or resistance to HIV medicines, the frequency of doctor visits, the cost of medical care, and general health and satisfaction.
The study will evaluate the efficacy and safety of both aliskiren monotherapy and aliskiren/enalapril combination therapy as compared to enalapril monotherapy, on morbidity and mortality in patients with chronic heart failure (NYHA Class II - IV.
This study compares indacaterol with tiotropium in terms of bronchodilation over 52 weeks
Magnesium iron hydroxycarbonate is a phosphate binder that absorbs phosphate from food, reducing the amount that the body can absorb. The purpose of this study is to assess the efficacy of magnesium iron hydroxycarbonate in subjects requiring haemodialysis, compared with a marketed phosphate binder, sevelamer hydrochloride.
