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 multiple dose, randomized, parallel, double-blind, double-dummy, multicenter and multinational Phase III study to determine the efficacy and safety of Aclidinium bromide 400μg/Formoterol Fumarate (AB/FF) 12 μg compared to individual components and TIO (Tiotropium) 18 μg when administered to patients with stable chronic obstructive pulmonary disease (COPD).
The purpose of this study is to characterise long-term safety and tolerability of intravenous anifrolumab.
This trial is designed to determine what effects the human body has on the investigational medicine, ABP 798, and what effects the body has on the investigational medicine after you have been given it, and if this is comparable to what is seen for the licensed medicine, rituximab, in patients with moderate or severe RA. This study will also assess if the investigational medicine is safe and effective in treating moderate or severe RA compared to the licensed medicine.
To compare the efficacy and safety of ofatumumab administered subcutaneously (sc) every 4 weeks versus teriflunomide administered orally once daily in patients with relapsing multiple sclerosis

Helicobacter pylori is a common bacterial infection. It can lead to severe stomach problems, including stomach cancer. Researchers want to look at samples of the bacteria. These H. pylori strains will be taken from chronically infected people. They want to identify the genetic and epigenetic differences in H. pylori strains. This could help predict which people who get infected with the bacteria will get stomach cancer. This could lead to the cancer being detected earlier. It could also mean less people get stomach cancer. Objectives: To study genetic variations of H. pylori strains based on samples from chronically infected people. To identify the features of strains that might lead to severe stomach problems or stomach cancer. Eligibility: People ages 30-70 years who need an upper endoscopy or who were recently diagnosed with stomach cancer Design: Participants will be screened by the doctor who does their procedure and a study nurse. Participants who have endoscopy will have ~6 biopsies removed. These are tissue samples. They are about the size of a grain of rice. Participants will allow the study team to access reports from their stomach exam. Participants with stomach cancer will donate some of the tissue that will be removed during their clinical care. They will allow the study team to access reports of their surgery. They will also allow them to access the microscope slides of their stomach.
This is a First in Human study to assess the feasibility, safety and effectiveness of the Zenflow Spring System in relieving the symptoms of obstructive Benign Prostatic Hyperplasia (BPH).
This is a Phase 3, randomized, double-blind, double-dummy, multicenter, prospective study to assess the efficacy, safety, and pharmacokinetics (PK) of eravacycline compared with meropenem in the treatment of complicated intra-abdominal infections (cIAIs).
The humanised IgG4 monoclonal antibody GNbAC1 targets the envelope protein (Env) of the human endogenous multiple sclerosis-associated retrovirus (HERV-W MSRV), which may play a critical role in multiple sclerosis (MS). This study evaluates the effect on MRI lesions parameters, the safety and pharmacokinetics of GNbAC1 in patients with relapsing remitting multiple sclerosis.
The purpose of this study is to assess the safety and tolerability of esketamine nasal spray in participants with treatment-resistant depression (TRD).
