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 6 arm study will evaluate the efficacy, safety, pharmacokinetics and pharmacodynamics of multiple doses and regimens of a GLP-1 analogue in patients with type 2 diabetes who are treated with a stable dose of metformin. Patients will be randomized to receive either subcutaneous placebo, or subcutaneous GLP-1 analogue, 5mg, 10mg or 20mg weekly, or 10mg or 20mg every 2 weeks. All patients will continue on their existing metformin treatment regimen throughout the study. The anticipated time on study treatment is <3 months, and the target sample size is 100-500 individuals.
The drug ABR-217620/naptumomab estafenatox is a fusion of two proteins, one that recognizes tumor cells and one that triggers an attack on the tumor cells by activating some white blood cells belonging to the body's normal immune system. This results in an accumulation of white blood cells in the cancer that can fight the cancer. This study will compare the safety and effectiveness (assessed by tumor status and survival) of ABR-217620/naptumomab estafenatox when given with standard therapy IFN-alpha to IFN-alpha alone in patients with advanced renal cell carcinoma (RCC).
To evaluate the efficacy, safety and tolerability of GSK372475 compared with placebo in the treatment of outpatients subjects with major depressive disorder to exhibit decreased pleasure, interest and energy.
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.
This study assessed the effect of pancrelipase delayed release capsules on fat and nitrogen absorption in subjects with PEI due to Chronic Pancreatitis and Pancreatectomy. There was a run-in with a 5-day of single-blind placebo treatment, followed by a 7-day Double-blind period and a 6-month Open-Label Follow-up.
The purpose of this study is to follow the health of subjects who have previously been enrolled in studies of CP-690,550 for treatment of their rheumatoid arthritis. Subjects are only eligible for this study after they have completed all participation in other studies of CP-690,550.
The purpose of this study is to determine the long-term effectiveness and safety of CP-690,550 for the treatment of rheumatoid arthritis. Subjects are eligible for this study only after participating in another "qualifying" study of CP-690,550 A sub-study will be conducted within the A3921024 study, this study will evaluate the immune response to pneumococcal and influenza vaccines in patients receiving CP-690,550
The purpose of this study is to determine the effectiveness and safety, over 6 months, of 6 dose regimens of CP-690,550, combined with methotrexate, for the treatment of adults with active rheumatoid arthritis.
This 2 arm study will investigate the efficacy, safety and tolerability of RAR Gamma versus placebo in ex-smokers with moderate or severe emphysema treated with optimal COPD therapy. Following optimization of COPD therapy (up to 6 weeks) patients will be randomized to receive either RAR Gamma (5mg) or placebo once daily using a 2:1 ratio (active:placebo), in addition to their standard therapy. Following the double-blind treatment period, patients will enter a 4-week follow-up period. The anticipated time on study period is 1-2 years, 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.
