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 phase III study of efficacy and safety of secukinumab versus placebo, in combination with glucocorticoid taper regimen, in patients with giant cell arteritis (GCA)
The purpose of this study is to evaluate the efficacy and safety of deucravacitinib versus placebo in participants with active psoriatic arthritis who are naïve to biologic disease-modifying anti-rheumatic drugs. The long term extension period will provide additional long-term efficacy and safety information.
The purpose of the study is to evaluate the safety of long-term therapy of bimekizumab in study participants with moderate to severe hidradenitis suppurativa (HS)
The purpose of this study is to evaluate the efficacy of nipocalimab versus placebo in participants with active systemic lupus erythematosus (SLE).
Primary Objective: To determine the efficacy of SAR441344 as measured by reduction of the number of new active brain lesions Secondary Objective: - To evaluate efficacy of SAR441344 on disease activity as assessed by other MRI measures - To evaluate the safety and tolerability of SAR441344 - To evaluate pharmacokinetics of SAR441344
This study is open to adults with schizophrenia. Schizophrenia can affect the way a person thinks, their memory and their mental functioning. Examples include struggling to remember things, or to read a book or pay attention to a movie. Some people have difficulty calculating the right change or planning a trip so that they arrive on time. The purpose of this study is to find out whether a medicine called iclepertin improves learning and memory in people with schizophrenia. Participants are put into two groups randomly, which means by chance. One group takes iclepertin tablets and the other group takes placebo tablets. Placebo tablets look like iclepertin tablets but do not contain any medicine. Participants take a tablet once a day for 26 weeks. In addition, all participants take their normal medication for schizophrenia. During this time, doctors regularly test learning and memory of the participants by use of questionnaires, interviews, and computer tests. The results of the mental ability tests are compared between the groups. Participants are in the study for about 8 months and visit the study site about 14 times. During this time, doctors regularly check participants' health and take note of any unwanted effects.
Axial spondyloarthritis (axSpA) is an immune-mediated inflammatory disease primarily affecting the axial skeleton. The most frequent axSpA symptom is chronic, often inflammatory back pain (IBP) that might be difficult to distinguish from other causes of chronic back pain (CBP). Many participants report persistent pain, including back pain, which impacts disease activity and quality of life including creating burdens such as sleep disturbance, social isolation, loss of productivity, as well as anxiety and depression. This study will assess the real-world effectiveness of upadacitinib on early and sustained pain control, and the association between pain and clinical/patient-reported outcomes in axSpA participants. Upadacitinib is being developed for the treatment of axSpA. Approximately 650 adult participants with active-axSpA will be enrolled across approximately 19 countries in Europe, North America, South America, and Asia-Pacific. Participants will receive oral upadacitinib tablets as prescribed by the physician prior to enrolling in this study in accordance with the terms of the local marketing authorization and professional and reimbursement guidelines with regards to dose, population and indication. Participants will be followed for 12 months. There may be a higher burden for participants in this study compared to usual standard of care. Participants will attend regular visits per routine clinical practice. The effect of the treatment will be checked by medical assessments, checking for side effects, and questionnaires.
A randomized, placebo-controlled study designed to evaluate the safety and efficacy of paltusotine (also known as CRN00808; an orally administered nonpeptide somatostatin agonist) in subjects with acromegaly previously treated with somatostatin receptor ligand (SRL) based treatment regimens.
The primary purpose of this study is to assess the long-term safety and tolerability of esketamine nasal spray in combination with a selective serotonin reuptake inhibitor/serotonin-norepinephrine reuptake inhibitor (SSRI/SNRI) in participants who have completed 32 weeks of esketamine nasal spray treatment in Study 54135419TRD3013 (NCT04338321).
The purpose of the study is to evaluate the safety and efficacy of talazoparib in combination with enzalutamide compared with placebo in combination with enzalutamide in participants with DDR-deficient mCSPC.
