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 vebicorvir (VBR, ABI-H0731) in combination with AB-729 is safe and effective in participants with chronic hepatitis B infection (cHBV) receiving a standard of care nucleos(t)ide/reverse transcriptase inhibitor (SOC NrtI).
The aim of this study is to investigate the efficacy, safety, and tolerability of iloperidone compared with placebo in treating acute manic or mixed episodes associated with Bipolar I Disorder.
A Phase 3 study to evaluate the safety and efficacy of efgartigimod PH20 subcutaneous in adult patients with primary immune thrombocytopenia
This placebo controlled study is intended to generate safety and efficacy data in order to provide a treatment option for COVID-19 in patients with a high risk of disease progression based on age or co-morbid medical conditions.
This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study evaluating the safety and efficacy of trilaciclib versus placebo administered prior to gemcitabine and carboplatin in patients receiving first- or second-line treatment for locally advanced unresectable/metastatic TNBC.
Reproductive age women diagnosed with poor ovarian response (POR) based on Bologna criteria with a history of at least two prior failed ICSI cycle will be recruited for the study. Antral follicle count (AFC), serum anti-mullerian hormone (AMH), and early follicular phase serum follicle stimulating hormone (FSH) levels will determined at baseline. Autologous blood obtained from peripheral vein will be used to prepare PRP following standard protocols and will be injected to both ovaries. Ovarian reserve parameters and ICSI outcomes will be determined.
Diabetic retinopathy (DR) is a diabetes complication caused by damage to the small blood vessels inside the retina at the back of the eye. Diabetic retinopathy may cause mild vision problems or eventually blindness. Diabetes is a condition that makes your blood sugar levels higher than they should be. In the early stages of diabetic retinopathy - called non-proliferative diabetic retinopathy (NPDR)- increased blood sugar levels lead to damage to the tiny blood vessels of the retina. This damage results in small outpouchings of the vessel lumens leading to rupture. At the same time the blood vessels can leak and making the retina swell and can cause so called macula edema. In these early stages of DR current treatment to reduce the risk of this eye complication is focused on controlling blood sugar levels and blood pressure. Participants in this study have NPDR, Type 2 Diabetes (T2D) and Chronic Kidney Disease (CKD), a condition in which the kidneys become damaged and do not work as they should. These participants are already taking part in one of the phase 3 studies (FIDELIO-DKD and FIGARO-DKD). They study the effect of Finerenone on delaying kidney disease progression and reducing the risk of events that may cause damage to the heart and blood vessels To learn more about the effect of Finerenone on diabetic retinopathy, data from routine eye examinations performed during the two phase 3 studies will be collected and analyzed. All male and female participants included in this study are at least 18 years.
Treatment of patients hospitalised for management of moderate COVID-19 infection
The purpose of this study is to evaluate the safety and efficacy of omadacycline as compared to moxifloxacin in the treatment of adults with community-acquired bacterial pneumonia.
This study is done to find out whether the medicine, semaglutide, has a positive effect on early Alzheimer's disease. Participants will either get semaglutide or placebo (a "dummy" medicine which does not contain any study medicine) - which treatment participants get is decided by an equal chance. The study will last for up to 173 weeks (about 3 years and 4 months). Participants will have 17 clinic visits and 1 phone call with the study doctor. The study includes various tests and scans. At 10 of the clinic visits participants will have blood samples taken. Participants must have a study partner, who is willing to take part in the study. Women cannot take part if pregnant, breastfeeding or plan to become pregnant during the study period. A cerebrospinal fluid (CSF) sub-study will be performed as a part of the study. The sub-study will be performed on a selection of sites based on their experience with CSF sampling and willingness to participate in this sub-study. The endpoints related to this sub-study are exploratory only.
