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.
1) To evaluate the efficacy and safety of cariprazine at a target dose of 3.0 mg/day compared with placebo in prevention of relapse in patients with bipolar I disorder whose current episode (i.e. index episode) is manic or depressive, with or without mixed features; 2) To evaluate the efficacy and safety of cariprazine at a target dose of 1.5 mg/day compared with placebo in prevention of relapse in patients with bipolar I disorder whose current episode (i.e. index episode) is manic or depressive, with or without mixed features who were initially stabilized on a target dose of 3.0 mg/day
The objective of this study is to assess the efficacy and safety of upadacitinib for the treatment of adolescent and adult participants with moderate to severe atopic dermatitis (AD) who are candidates for systemic therapy.
The purpose of this study is to evaluate the efficacy and safety of Ontamalimab in inducing clinical remission and endoscopic response in participants with moderate to severe Crohn's Disease.
The primary purpose of this study is to demonstrate pharmacokinetic bioequivalence of ofatumumab injected by Pre-filled Syringe (PFS) versus Auto-Injector (AI) devices and thereby establish a bridge between the ongoing Phase 3 program and the to-be-marketed drug-device combinations
This study is designed to evaluate the efficacy, safety, and pharmacokinetics of UTTR1147A compared with vedolizumab and with placebo in the treatment of participants with moderate to severe UC. This study will consist of two parts, Part A and Part B. Part A will test the induction of clinical remission and Part B will test the durability of clinical remission.
This study will look at the change in participants' body weight from the start to the end of the study. The weight loss in participants taking semaglutide (a new medicine) will be compared to the weight loss of participants taking "dummy" medicine. In addition to taking the medicine, participants will have talks with study staff about healthy food choices, how to be more physically active and what you can do to lose weight. Participants will either get semaglutide or "dummy" medicine - which treatment participants get, is decided by chance. Participants will need to take 1 injection once a week. The study medicine is injected with a thin needle in a skin fold in the stomach, thigh or upper arm. The study has two phases: A main phase and an extension phase.The main phase will last for about 1.5 years. Participants will have 15 clinic visits and 10 phone calls with the study doctor. Extension phase: Approximately 300 participants will continue in the extension phase in the following countries only: Canada, Germany, the UK and selected sites in the US and Japan. These participants will be in the study for about 2.5 years.They will not receive treatment, but will attend another 5 follow-up visits with the study doctor.
The study will evaluate safety and effectivity of the BTL-FR2000 device for the treatment of facial wrinkles.
The study is a prospective multi-center open-label single-arm study. The subjects will be enrolled and assigned into a single study group. Subjects will be required to complete four (4) treatment visits and four follow-up visits, 1 month, 3, 6 and 12 months after the final treatment. At the baseline visit photographs of the abdomen will be taken. In addition, patient umbilical circumference will be measured and the subject's weight will be recorded. In addition, at the last therapy visit, subjects will receive Subject Satisfaction and Therapy Comfort Questionnaires to fill in. Safety measures will include documentation of adverse events (AE) including subject's experience of pain or discomfort after the procedure. Following each treatment administration and at the follow-up visits, subjects will be checked for immediate post-procedure adverse event assessment. Post-procedure evaluation (follow-up visits) will be conducted 1 month, 3, 6 and 12 months after the final treatment. Umbilical circumference and weight measure will be conducted at every follow-up visit. Also, subject's satisfaction will be noted. During the first (1 month), third (6 months) and last (12 months) follow-up visits, photographs of abdomen will be taken.
The primary hypothesis in this trial is that the treatment with vericiguat 10 mg or 15 mg in patients with HFpEF improves the KCCQ PLS (Kansas City Cardiomyopathy Questionnaire Physical limitation score) compared to placebo after 24 weeks of treatment.
The study is a prospective multi-center open-label single-arm study. The subjects will be enrolled and assigned into a single study group. Subjects will be required to complete four (4) treatment visits and three follow-up visits, 2 months, 6 and 12 months after the final treatment. At the baseline visit photographs of the abdomen will be taken. In addition, adipose/muscle layer thickness will be measured with the magnetic resonance imaging and the subject's weight will be recorded. Safety measures will include documentation of adverse events (AE) including subject's experience of pain or discomfort after the procedure. Following each treatment administration and at the follow-up visits, subjects will be checked for immediate post-procedure adverse event assessment. In addition, at the last therapy visit, subjects will receive Subject Satisfaction and Therapy Comfort Questionnaires to fill in. Post-procedure evaluation (follow-up visits) will be conducted 2, 6 and 12 months after the final treatment. During those visits, magnetic resonance imaging, photographing and weight measure will be conducted. Subject Satisfaction Questionnaire will be given at every follow-up visit.
