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.
Chronic hepatitis B virus (HBV) infection is a significant worldwide medical problem. GSK3228836 demonstrated target engagement in CHB participants who were not on treatment and in CHB participants on stable nucleos(t)ide therapy. This study is intended to evaluate if treatment with GSK3228836 can achieve sustained virologic response (SVR), that is hepatitis B virus surface antigen (HBsAg) less than (<) lower limit of quantitation (LLOQ) and HBV deoxyribonucleic acid (DNA) <LLOQ sustained for 24 weeks post-GSK3228836 treatment end. In addition, the study will also evaluate the safety, tolerability, pharmacokinetic and pharmacodynamic properties of GSK3228836 in the 4 dosing regimens. This study will assess the efficacy and safety of treatment with GSK3228836 in two populations of participants with CHB; participants on stable nucleos(t)ide treatment (Cohort 1) and participants who are not currently on nucleos(t)ide therapy (Cohort 2). For each population, participants will be randomized into one of the 4 different parallel arms to receive treatment. The study will consist of a screening, treatment, and post-treatment follow-up phase. Approximately, 440 participants will be enrolled in the study.
The purpose of this study is to compare the efficacy of vortioxetine versus desvenlafaxine after 8 weeks of treatment in patients that have tried one available treatment without getting the full benefit
This study will evaluate the clinical safety and the performance of the BTL-785F system equipped with BTL-785-2 applicator for non-invasive treatment of facial wrinkles.
The purpose of the study is to assess safety, tolerability and pharmacokinetics (PK) of oral UCB8600.
The primary objective of the study is to evaluate the efficacy of dupilumab on lung function in participants with Allergic Bronchopulmonary Aspergillosis (ABPA). The secondary objectives of the study are: - To evaluate the effects of dupilumab on exacerbations in participants with ABPA - To evaluate the effects of dupilumab on ABPA-related exacerbations - To evaluate the effects of dupilumab on hospitalization/emergency department (ED)/urgent care visits in participants with ABPA - To evaluate the effects of dupilumab on asthma control in participants with ABPA - To evaluate the effects of dupilumab on health-related quality of life (HRQoL) in participants with ABPA - To evaluate the effects of dupilumab on serum total immunoglobulin E (IgE) and Aspergillus-specific IgE concentrations - To evaluate the effects of dupilumab on Fractional exhaled Nitric Oxide (FeNO) levels - To evaluate safety and tolerability of dupilumab in participants with ABPA - To evaluate dupilumab concentrations in serum and the incidence of anti-dupilumab antibodies in participants with ABPA
The purpose of the study is to demonstrate the long-term safety, tolerability and efficacy of bimekizumab in patients with active axial spondyloarthritis (axSpA, also known as radiographic axSpa (r-axSpA)) including ankylosing spondylitis (AS) and nonradiographic axial spondyloarthritis (nr-axSpa).
The purpose of this study is to evaluate the effect of finerenone compared to placebo (a tablet without active substance) in the reduction of cardiovascular death (generally meaning death due to disease of the heart or blood vessels) and total Heart Failure (HF) events, including HF hospitalization and urgent visits for HF(generally meaning a hospital stay or urgent presentation to a healthcare unit due to worsening symptoms of heart failure) in patients suffering from HF with an ejection fraction greater than or equal to 40%. Researchers will also collect information on how much the heart disease has impact on patient's lives, change of kidney function, and how well finerenone treatment is tolerated. The study plans to enroll 6000 male and female patients of the age of 40 years and above suffering from heart failure with ejection fraction greater than or equal to 40%. Participants will take the study product as oral tablet with a dose between 0 (Placebo) 40 mg once daily. Study duration will be up to 43 months.
This is a multicenter long-term extension study designed to evaluate the long-term safety and tolerability of faricimab administered by intravitreal (IVT) injection at a personalized treatment interval (PTI) to participants who enrolled in and completed one of the two Phase III studies, GR40349 (NCT03622580) or GR40398 (NCT03622593), also referred to as the parent studies.
In this study researchers want to learn more about changes in visual acuity (clarity of vision) with a high dose treatment with Aflibercept (Eylea) in patients suffering from neovascular age-related macular degeneration (nAMD). Neovascular AMD is an eye disease that causes blurred vision or a blind spot due to abnormal blood vessels that leak fluid or blood into the light sensitive lining inside the eye (retina). The fluid buildup causes the central part of the retina (macula) responsible for sharp, straight-ahead vision to swell and thicken (edema), which distorts vision.
This clinical study aims to assess the efficacy of TOTUM-63, a mix of 5 plant extracts, consumed at the daily regimen of three times per day on glucose and lipid homeostasis in dysglycemic subjects. The hypothesis is that TOTUM-63, consumed 3 times per day, is superior to placebo for decrease of fasting plasma glucose (FPG) concentration after 24 weeks of consumption.
