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 study to evaluate whether macitentan is an effective and safe treatment for patients with heart failure with preserved ejection fraction (HFpEF) and pulmonary vascular disease. The primary objective is to evaluate whether macitentan 10 mg reduces N-terminal pro-brain natriuretic peptide (NT-pro-BNP) as compared to placebo in these patients.
The purpose of this study was to compare the efficacy and safety of ceftobiprole medocaril versus a comparator in the treatment of patients with complicated Staphylococcus aureus bacteremia (SAB).
This was a randomized, double-blind, active-controlled, parallel-group, multicenter study in adult hospitalized patients to establish the safety and efficacy of ceftobiprole medocaril compared with vancomycin plus aztreonam in the treatment of acute bacterial skin and skin structure infections (ABSSSIs).
The purpose of the study was to evaluate the efficacy and safety of secukinumab 150 mg compared to placebo in the early management (Baseline to Week 8) of spinal pain, disease activity, fatigue, and predictability of disease flares in patients with axial spondyloarthritis (axSpA) who had an inadequate response to prior non-steroidal anti-inflammatory drugs (NSAIDs). This study also explored the efficacy and safety of secukinumab 300 mg compared to secukinumab 150 mg from Week 8 to Week 24 in order to assess the potential additional benefits of dose escalation in patients with axSpA.
The primary objective of this study was to evaluate the long-term safety and tolerability of olokizumab (OKZ) 64 mg administered subcutaneously (SC) once every 2 weeks (q2w) or once every 4 weeks (q4w) in subjects with moderately to severely active rheumatoid arthritis (RA) who previously had completed 24 weeks of double-blind treatment in Study CREDO 1, 2 or 3 (core studies). The long-term efficacy, immunogenicity, the physical function and quality of life of subjects received long-term treatment with OKZ were assessed as well.
This is a multicenter, Phase 2, double-blind, placebo-controlled study in subjects with active Ankylosing Spondylitis (AS). A total of approximately 100 subjects will be randomized to one of 2 treatment arms in a 1:1 ratio: oral filgotinib tablets q.d. or matching placebo q.d. Treatment duration will be 12 weeks. Each subject will stay in the study for a maximum of 20 weeks (from Screening visit to Follow-up visit).
The purpose of this study is to assess the efficacy of ruxolitinib against best available therapy in participants with steroid-refractory chronic graft-versus-host disease (SR cGvHD).
Part 1 of this study will establish a recommended Phase II (RPII) dose for the triplet combination of NC-6004 plus 5-Fluorouracil (5-FU) and cetuximab. Part 2 will provide the efficacy signal of the triplet combination in this patient population.
Evaluation of the long-term safety and tolerability of vortioxetine in child and adolescent patients with a Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5™) diagnosis of MDD
The purpose of this study is to evaluate the efficacy and safety of risankizumab versus placebo during induction therapy in participants with moderately to severely active Crohn's disease (CD).
