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 the study is to compare, after 8 weeks, the efficacy of SR58611A vs. placebo in patients with Major Depressive Disorder who are on concomitant treatment with escitalopram. The secondary objective of this study is to document clinical safety and tolerability of SR58611A in association with escitalopram.

Eligible patients will be randomized to receive either 1)Valcyte 900mg po bid or 2)ganciclovir 5mg/kg iv bid. The anticipated time on study treatment is 1-2 years and the target sample size is 100-500 individuals.
This study is being conducted to compare the efficacy and safety of pazopanib in combination with lapatinib with that of lapatinib alone or pazopanib alone in subjects with metastatic cervical cancer
Rosiglitazone (RSG) has been tested and is approved as a treatment for type II diabetes mellitus, a disease that occurs when the body ineffectively uses glucose. RSG XR, the investigational drug, is an extended-release form of RSG. This study tests whether RSG XR safely provides benefit to people with mild to moderate Alzheimer's disease (AD). RSG XR is a new approach to AD therapy and this study tests whether one's genes alter the effectiveness of RSG XR. Glucose is used by cells to make energy that they need to live. Changes in the ability of cells to use of glucose can lead to diseases like diabetes. Glucose levels may be lower in the brains of AD patients, and their brain cells may also use glucose less well than in unaffected people. The proper function of brain cells may be critical to memory and thought. If brain cells use glucose poorly, this might impact AD. Drugs that help brain cells properly use glucose may help a person maintain normal memory and thinking. Data suggesting that RSG may help AD patients was first seen in a small study at the Univ. of Washington and then from a larger international GSK study. In the first study, those receiving RSG once daily for 6 months scored better on 3 tests of memory and thought than those who did not receive RSG. In the GSK study, those that benefited most from therapy with RSG XR had a specific genetic pattern. They lacked the gene that caused them to produce apolipoprotein E e4 (APOE e4). Subjects who have the APOE e4 gene may have two copies, one from each parent, or they may have only one APOE e4 gene meaning that they inherited either the APOE e2 or APOE e3 version of the gene from one parent. Subjects with one copy of the APOE e4 gene remained fairly stable while those with two copies of APOE e4 continued to worsen during the 6-month treatment. This study will directly test the effect of RSG XR on people who either have or lack the APOE e4 gene.
This is a randomised, double-blind, placebo-controlled, multicentre, global Phase III trial comparing the efficacy of adjuvant oral lapatinib versus placebo in high-risk subjects with head and neck cancer following surgery. Lapatinib or placebo will be administered post-operatively in combination with chemoradiotherapy followed by maintenance with lapatinib or placebo for 1 year. The primary goal is to determine if lapatinib is effective at reducing the recurrence of the disease in these high-risk patients.
It has been shown that women who have dense breasts have an increased risk of breast cancer compared with women whose breasts are less dense. However, while breast density may be a risk factor, the etiology of the relationship between breast cancer and breast density is not understood. Furthermore, it is well recognized that breast cancer can still develop in women whose breasts are not dense. At menopause, the amount of breast glandular tissue and stroma naturally decreases due to a lack of hormonal stimulation. This is characterized as a decrease in the mammographic density. Although certain medications, including hormone therapy (HT) and dopamine antagonists can increase breast density, these effects are reversible upon discontinuation of the specific agent. Other medications such as the selective estrogen receptor modulators (SERM), raloxifene (RAL) and tamoxifen, have been shown to not affect breast density and allow the normal age-related changes to occur. The effects of bazedoxifene (BZA), a new SERM, on breast density are not known. The purpose of this study is to examine the effect of BZA on breast density changes over 24 months in postmenopausal women. The results may be useful for clinicians to understand the effect of BZA on breast density and its mammographic effects. This is an observational, multicenter, double-blind, randomized, placebo- and active comparator-controlled study. It is also an ancillary that will use women who are already participants in a phase 3 trial for fracture reduction (protocol 3068A1-301-WW; primary study). In the primary study, subjects received BZA 20 mg, BZA 40 mg, RAL 60 mg, or placebo. This ancillary study will request a subset of participants to use their mammograms taken in this study. Their mammogram will be digitized by a central imaging center. A single radiologist will perform the quantifications of breast density from the digitized mammograms.
The primary objective of this study is to evaluate the efficacy of pregabalin as compared to placebo in the treatment of patients with general anxiety disorder (GAD). Efficacy will be measured by the improvement in the total Hamilton Anxiety Rating Scale (HAM-A) scores from baseline observed following 8 weeks of double-blind treatment or at earlier termination during the double-blind treatment phase and analyzed using a mixed linear model for repeated measures.
This 2 arm study will evaluate the efficacy and safety of Tamiflu in the seasonal prophylaxis of influenza in immunocompromised patients (as represented by transplant recipients). Transplant recipients enrolled when influenza is circulating in the community will be randomized to receive Tamiflu syrup or capsules 30mg-75mg daily (depending on body weight) or placebo for 12 weeks. Influenza symptoms and safety data will be recorded throughout the study. The anticipated time on study treatment is <3 months, and the target sample size is 100-500 individuals.
This is an observational study with a drug called Nebido, a new testosterone replacement therapy, which is available for the treatment of male hypogonadism. The benefit and safety of Nebido have already been thoroughly evaluated through well controlled clinical trials. The main purpose of this observational study is to confirm the established safety profile of Nebido in daily clinical practice.
SMP-986 is a compound being developed for the treatment of overactive bladder syndrome (OABS). This clinical study is designed to test the hypothesis that SMP-986 at doses of 20mg, 40mg, 80mg or 120mg provides greater symptom relief in OABS compared to placebo. The hypothesis will be tested by measuring the change in mean voids/24 hrs after treatment with SMP-986 compared to placebo, as well comparing the change in: the severity of urgency episodes, mean number of urgency episodes/24 hr, mean number of incontinence episodes/24 hr and the mean void volume/void between SMP-986 and placebo.
