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.
Primary: To evaluate the efficacy of satavaptan in the absence of concomitant diuretic drugs in reducing the recurrence of ascites. Secondary: To evaluate the tolerability and safety of satavaptan in the absence of concomitant diuretic drugs over a 52-week treatment period in patients with cirrhosis of the liver and recurrent ascites. The one-year double blind placebo controlled period is extended up to 2 years in a long term safety study (PASCCAL-2).
Primary To evaluate the efficacy of satavaptan on top of diuretic drugs in reducing the recurrence of ascites. Secondary To evaluate the tolerability and safety of satavaptan on top of diuretic drugs over a 52-week treatment period in patients with cirrhosis of the liver and recurrent ascites. The one-year double blind placebo controlled period is extended up to 2 years in a long term safety study (PASCCAL-2).
The purpose of this study is to evaluate if Leukine can induce clinical response or remission in patients with Crohn's disease.
To determine if therapy with Zometa® (zoledronic acid) 4mg will be effective in preventing the occurrence of bone metastases in prostate cancer patients at high risk of developing them. In addition, pain and analgesic scores and overall safety are to be evaluated throughout the study.
This is a randomized, open-label, multinational, phase III study in women with histologically- or cytologically-confirmed advanced NSCLC who are chemotherapy naïve and have PS 2. Study drug will be administered on day 1 of each 21 day cycle
The purpose of this study is to determine the safety and effectiveness of long-term therapy with rosuvastatin compared with a placebo, and to evaluate whether treatment with rosuvastatin might be effective in reducing the risk of major cardiovascular events.
Lung infections are a chronic problem for patients with cystic fibrosis (CF). Some patients with CF may have a type of bacteria called Pseudomonas aeruginosa in their lungs that can cause infections or make their symptoms worse. Tobramycin inhalation solution (TOBI) is an approved antibiotic, which is inhaled directly into the lungs, and can be used to manage these infections. Tobramycin inhalation powder (TIP) is a new, experimental powder formulation of tobramycin that is inhaled directly into the lungs using a T-326 inhaler. The purpose of this research study is to determine if TIP is safe and effective when compared to placebo (a powder with no medicine) treatment.
The purpose of this early Phase II multicenter trial is to determine the objective clinical response to GPX-100, an anthracycline similar to doxorubicin, in up to 40 patients with newly diagnosed metastatic breast cancer. GPX-100 is unique among anthracyclines because it is not converted to doxorubicinol during metabolism in the body. This metabolite has been shown to be a major cause of damage to the heart (cardiotoxicity) in laboratory studies. Eligible patients who are enrolled in this study will receive GPX-100 as a single agent at the beginning of as many as 8 three week long cycles of chemotherapy. Objective measurements of tumor response will be made by computed tomography (CT) scans.
The purpose of this study is to determine whether maximal estrogen suppression achieved via the combination of an experimental drug, atamestane, plus an FDA-approved drug, toremifene (Fareston®), is more effective than another approved drug, letrozole (Femara®), in delaying the growth of breast cancer, and whether the side effects of the combined hormonal therapy are different from the side effects of letrozole.
The primary purpose of this study is to determine whether abetimus sodium is more effective than placebo in delaying time to renal flare in SLE patients with a history of renal disease.
