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 this study is to determine if Cediranib when added to chemotherapy is more effective than chemotherapy alone in prolonging life expectancy and slowing disease progression in patients with previously untreated metastatic colorectal cancer.
This study is designed to determine if the investigational drug is effective and safe in individuals with asthma.
The purpose of this study is to assess the safety and effects of VX-702 in subjects with moderate to severe rheumatoid arthritis and who are taking the drug methotrexate.
The purpose of this study is to evaluate the combination of alogliptin, once daily (QD), and pioglitazone in patients with type 2 diabetes mellitus who are inadequately controlled with diet and exercise alone.
Ticagrelor is a new, reversible binding, anti-platelet medication. Anti-platelet medications work to prevent the formation of blood clots. Ticagrelor is being developed as a treatment for patients with acute coronary syndrome (ACS). ACS is a term that is used to describe both heart attacks in progress or the imminent threat of a heart attack. ACS is usually caused by the formation of a blood clot in an artery that partially or totally blocks the blood supply to a portion of the heart muscle. Ticagrelor will be compared with clopidogrel to determine which drug, when either is used in conjunction with aspirin, is better at reducing deaths from vascular causes, future heart attacks and/or strokes in patients with ACS.
The purpose of this study is to investigate the efficacy of inhaled ciclesonide at three different dose levels compared with placebo with respect to pulmonary function, asthma symptoms, and use of rescue medication in children with asthma. Treatment medication will be administered as follows: ciclesonide or placebo will be inhaled once daily. The study consists of a baseline period (2 to 4 weeks) and a treatment period (12 weeks). The study provides further data on safety and tolerability of ciclesonide.
This study is a phase 3b, multicentre, randomised, open label, parallel group study. A 4-week run-in period will be followed by a median of 6 years of treatment with study medication in addition to continuation of background glucose lowering therapy. Patients inadequately controlled on background metformin will be randomised to receive, in addition to metformin, either rosiglitazone or a sulfonylurea(glibenclamide, gliclazide or glimepiride) in a ratio of 1:1. Patients inadequately controlled on background SU will be randomised to receive, in addition to SU, either rosiglitazone or metformin in a ratio of 1:1. Equal numbers of patients receiving background metformin and SU at entry will be entered into the study.
The purpose of this study is to evaluate the efficacy of TAK-583, once daily (QD), in relieving pain in subjects with postherpetic neuralgia.
To compare efficacy and safety of Sunitinib and Capecitabine in subjects with advanced breast cancer who failed both a taxane and an anthracycline chemotherapy regimen or failed with a taxane and for whom further anthracycline therapy is not indicated
The purpose of this study is to assess the efficacy and safety of AZD6244 (ARRY-142886)versus capecitabine in patients with advanced or metastatic pancreatic cancer who have failed first-line therapy with gemcitabine. Following baseline assessments, a minimum of 64 patients in approximately 5-6 centers from the US will be treated with either AZD6244 or capecitabine. Treatment will be continued for as long as the patients receive clinical benefit. The status of all patients will be checked (whether they are still taking treatment or not) approximately 3 months after the last patient has entered the study.
