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.
The purpose of the study is to assess the efficacy of flecainide controlled release (CR) in the prevention of recurrent AF during 9 months of active treatment compared to placebo in patients with only one documented AF episode.
This study is a multicenter, 9 months, open label extension study for all patients who are willing and eligible to continue from the pivotal, double-blind S308.3.002 study.
This study is a multicenter, randomized, double blind, parallel group study of 3 months' treatment with SLV308 administered as a monotherapy in patients with advance stage PD. An open label safety extension to this study is planned as a separate protocol for patients who are willing and eligible to participate.
Primary objective: To determine the effect of Rimonabant 20mg on the co-primary endpoint including Fasting Plasma Glucose (FPG), HDL-Cholesterol (HDL-C) and triglyceride (TG) levels over a period of 12 months when prescribed with a mild hypocaloric diet in abdominally obese patients with impaired fasting blood glucose and with or without associated comorbidities. Main Secondary objectives: To determine the effect of 12 months Rimonabant treatment versus placebo on changes in waist circumference (WC), body weight, glycemic parameters and lipid parameters. To assess the safety of 12 months Rimonabant treatment versus placebo in these patients.
Pre-Term Labor (prior to 37 weeks gestation) is the largest single cause of infant morbidity and mortality and is frequently associated with long-term disability. Oxytocin is a hormone produced by the body during labor. GSK221149A is an experimental drug that will be used to block the effects of oxytocin, and therefore pause or prevent contractions. In this study, patients with preterm labor will be given an intravenous infusion of GSK221149A over approximately 12 hours followed by an oral tablet in Parts A and B. In part C of this study, patients with preterm labor will be give an intravenous infusion of GSK221149A over approximately 48 hours. The use of a rescue tocolytic is allowed in the study.
The study is a 24 months randomized, double-blind, Placebo-controlled, multi-center clinical trial with an optional 12 months open label extension. The primary objective of the study is to evaluate the effect of fetal bovine serum [FBS]-free/human serum albumin [HSA]-free formulation of Interferon [IFN] beta-1a (RNF) 44 microgram (three times weekly and once weekly) versus placebo on the time to conversion to McDonald multiple sclerosis (MS) criteria (2005) in subjects with a first clinical demyelinating event at high risk of converting to MS. The main secondary objective of study is to evaluate the effect of RNF 44 microgram (three times weekly and once weekly) versus placebo on the "Time to conversion to clinically definite MS (CDMS)" in subjects with a first clinical demyelinating event at high risk of converting to MS. At the end of 24 month double-blind core REFLEX trial, subjects who will not convert to CDMS and decide to receive open-label (OL) treatment will be enrolled into an open-label, 12 month extension period to evaluate the effect of RNF 44 mcg three times weekly treatment on the time to conversion to McDonald MS and time to conversion to CDMS.
The purpose of this study is to compare the efficacy and safety of rivaroxaban with warfarin for the prevention of blood clots in the brain (referred to as stroke) and blood clots in other parts of the body referred to as non-central nervous system systemic embolism) in patients with non-valvular atrial fibrillation (a heart rhythm disorder).
Patients, who are considered suitable by their physicians to take part in this research, will have a physical examination (including an Electrocardiogram (ECG)), blood and urine samples taken, as well as a sample of the secretions or tissue around their infection site. In addition, the site of the infection will be photographed. The patients will be randomly assigned one of the treatments: intravenous (IV)/per oral (PO) moxifloxacin (drug under evaluation) or IV piperacillin/tazobactam followed by PO amoxicillin/clavulanic acid (i.e., one of the reference treatments for this kind of infection). The maximum treatment duration will be 21 days, and the minimum will be 7 days. During the hospitalization, the patients will have a physical examination every day. On Day 3-5 during therapy as well as at the end of treatment, the patients will have repeated examinations. These tests and evaluations will be repeated 14 to 28 days after the end of treatment. During this visit, blood and urine samples will be taken only if judged necessary by the physicians.
The purpose of Part 1 of the study is to determine the safety of the combination of Siltuximab (CNTO 328) and bortezomib (Velcade). The purpose of Part 2 of the study is to compare the length of progression free survival for those patients given CNTO 328 and bortezomib to those patients given bortezomib alone.
This is a randomized, open label, phase III study to evaluate the ability of rituximab maintenance therapy to prolong event-free survival in aggressive NHL. Patients will be screened after successful standard induction therapy (CR or Cru following standard R-CHOP-like therapy with 8 infusions of rituximab plus CHOP-like chemotherapy (4-8 cycles). Patients will be followed until an event occurs as defined in the protocol. To evaluate the clinical efficacy of rituximab maintenance therapy as compared to observation in patients with aggressive B-cell Non-Hodgkins lymphoma or follicular lymphoma grade 3b who have achieved a complete remission after appropriate first-line therapy, measured by event-free survival (EFS), 440 patients with DLCBL or follicular NHL grade 3 (220 per arm) will be recruited.
