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 is a multicenter randomized, double-blind, placebo-controlled, parallel-group, dose-ranging phase 2b study to investigate the hepatic and renal safety and tolerability of multiple dose administration of two dose levels of CSL112 compared with placebo in subjects with acute myocardial infarction (AMI).
Irritable Bowel Syndrome with diarrhoea (IBS-D) is a functional gastrointestinal disorder characterised by chronic or recurrent abdominal pain or discomfort and diarrhoea. This trial aims at the evaluation of the efficacy and safety of oral ibodutant 10 mg once daily as compared to placebo in women with IBS-D over a 12-week treatment period.
The purpose of this study is to evaluate if the time to first pulmonary exacerbation of bronchiectasis or its frequency can be prolonged by inhalation of ciprofloxacin for 28 days every other 28 days or for 14 days every other 14 days over 48 weeks.
This is a Phase IIIa, multicenter, randomized, stratified (reversibility status), double-blind, parallel-group study to evaluate the efficacy and safety of FF/VI 100/25 micrograms (mcg) once daily (QD) compared with VI 25 mcg QD, administered in the morning via the ELLIPTA™ inhaler. The primary objective of this study is to evaluate the contribution on lung function (as measured by trough forced expiratory volume in one second [FEV1]) of FF 100 mcg to the FF/VI 100/25 mcg QD combination by comparison of the latter with VI 25 mcg QD and the safety of FF/VI 100/25 mcg over a 12-week treatment period in subjects with COPD. ELLIPTA™ is a registered trademark of GlaxoSmithKline.
There is initial evidence that the choice of anesthesia can influence survival in the specific setting of coronary artery bypass grafting surgery (CABG). A recent international consensus conference included volatile agents among the few drugs/techniques/strategies that might reduce perioperative mortality in cardiac surgery and that should be further studied. Volatile anesthetics (desflurane, isoflurane and sevoflurane) have non-anesthetic pharmacological characteristics that confer cardiac protection when compared to Total IntraVenous Anesthesia (TIVA). Several randomized controlled studies were summarized in a meta-analysis that documented a reduction in perioperative cardiac troponin release and mortality in patients receiving volatile anesthetics when compared to patients receiving a TIVA. There are four published studies (Bignami et al. 2009) (De Hert et al. 2009) (Jackobsen et al. 2007) (Landoni et al. 2007) suggesting that these benefits can translate into a reduced mortality rate in patients receiving volatile agents. The level of evidence for these four studies is not high (one meta-regression, one underpowered randomized controlled study, one retrospective study and one meta-analysis of small randomized studies) and there is need for a large multicentre randomized controlled study to confirm these findings, as suggested by the international consensus conference on this topic published in 2011 (Landoni et al 2011). The purpose is to provide a large multicentre controlled randomized trial to demonstrate that volatile anesthetics can reduce 1 year mortality from 3% to 2% in patients undergoing CABG (either with or without cardiopulmonary bypass). The results of this study can support the use of volatile agents in all CABG procedures worldwide (more than 500.000 per year) with 2.500 lives saved per year (in the hypothesis that nowadays half the procedures are performed with a TIVA and that 1 year mortality can be reduced from 3% to 2% using volatile agents).
This Phase III, randomized, double-blind, placebo-controlled, multicenter study will assess the efficacy and safety of lebrikizumab in adult patients with mild to moderate asthma treated with short-acting beta-agonist (SABA) therapy alone. Patients will be randomized in a 1:1:1 ratio to receive either blinded lebrikizumab or placebo treatment by subcutaneous (SC) injection (every 4 weeks for a total of 3 doses) or open-label treatment with Singulair (Montelukast; 10 mg daily). Time on study treatment will last 12 weeks.
This trial is conducted in Africa, Europe and North America. The purpose of the trial is to investigate the efficacy and safety of liraglutide adjunct to insulin treatment in type 1 diabetes.
This is a sub-study of the OSKIRA-4 study, (D4300C0004, NCT01264770) to explore alternative and more sensitive modalities for measuring the beneficial effects of syk inhibition with fostamatinib in patients with active RA. This MRI sub-study was reported later than the main study due to recruitment delays at specialist imaging sites and so is registered and presented entirely separately to the main study results. This study will investigate the impact of treatment on joint activity and damage by assessing synovitis, osteitis, bone erosions and joint space narrowing.
This post-marketing study is designed to compare the safety of tofacitinib versus TNF inhibitor with respect to major cardiovascular adverse events and malignancies, excluding non-melanoma skin cancers when given to subjects with rheumatoid arthritis. Other safety events, including non-melanoma skin cancers, hepatic events, infections, and efficacy parameters will be collected and evaluated in the study.
The purpose of this study is to support selection of an appropriate safe and efficacious dose for study in further development.
