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 primary objective of this study is to obtain long term safety data of ataluren in male participants with nonsense mutation dystrophinopathy (who participated and completed a previous Phase 3 study of ataluren [PTC124-GD-020-DMD {NCT01826487}]) to augment the overall safety database. Screening and baseline procedures are structured to avoid a gap in treatment between the double-blind study (PTC124-GD-020-DMD) and this extension study. This study may be further extended by amendment until either ataluren becomes commercially available or the clinical development of ataluren in duchenne muscular dystrophy (DMD) is discontinued.
The purpose of this study is to gather information about the steady-state plasma concentrations of aripiprazole, olanzapine, quetiapine and their relevant metabolites, at various dose levels and at different time points after dosing. In addition, comparison of capillary drug concentrations vs. venous drug concentrations will be performed for aripiprazole, olanzapine, paliperidone, quetiapine, risperidone and their relevant metabolites.
The purpose of the study was to evaluate the efficacy of tapentadol oral solution, based on the total amount of supplemental opioid analgesic used over 12 hours or 24 hours after initiation of investigational medicinal product (IMP) in children and adolescents who had undergone surgery that would produce moderate to severe pain during opioid treatment.
To evaluate the long-term safety and tolerability of idalopirdine (Lu AE58054) as adjunctive therapy to donepezil in patients with mild-moderate Alzheimer's Disease (AD).
The primary objective of this study was to assess the long term safety of fostamatinib in subjects with persistent/chronic ITP
The purpose of this study is determine whether Anagrelide Retard is non-inferior to anagrelide immediate release form in treatment of essential thrombocythemia. Essential thrombocythemia (ET) is a myeloproliferative neoplasm characterised by a sustained increase in platelet counts above the normal value (> 450 x 109/L) and increased megakaryopoiesis in the bone marrow, without secondary causes of thrombocytosis. Anagrelide hydrochloride selectively reduces platelet numbers by inhibiting megakaryocyte development and maturation in humans, without affecting other cell lineages. Anagrelide Retard is a new, prolonged release (PR) tablet formulation of anagrelide developed by AOP Orphan Pharmaceuticals AG. The rationale for developing this new formulation is based on the assumption of having a better tolerability while maintaining an efficacy comparable to that of the immediate release formulation. The effects of Anagrelide Retard and Thromboreductin® will be compared in terms of mean platelet count measured by a central laboratory/centralized method at 3 time points during the maintenance phase.
The purpose of this study is to determine whether fostamatinib is safe and effective in the treatment of persistent/chronic Immune Thrombocytopenic Purpura (ITP).
The purpose of this trial is to confirm if benralizumab can reduce the use of maintenance OCS in systemic corticosteroid dependent patients with severe refractory asthma with elevated eosinophils.
This study will assess efficacy of secukinumab, compared to ustekinumab, in patients that have plaque-type psoriasis
The objectives of this study are to evaluate the efficacy, safety, pharmacodynamic, pharmacokinetic and immunogenic profiles of satralizumab in participants with NMO and NMOSD.
