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 purpose of this study is to monitor ongoing safety in participants with ulcerative colitis (UC) and Crohn's disease (CD) and to provide access to vedolizumab for qualifying participants who, in the opinion of the investigator, continue to derive benefit from vedolizumab and for whom continued treatment with vedolizumab is desired because there is no other comparable product available or the participant may be expected to develop worsening of disease if they were to modify treatment.
The objective of this study is to evaluate the long-term safety and efficacy of Ace-ER treatment in subjects with GNEM.
The primary objective of this Phase 2 study is to evaluate the safety of open-label 6 g/day Ace-ER in GNEM participants with severe ambulatory impairment.
This is a Phase 3, open-label, international, multi-center, efficacy, and safety study of avelumab in combination with and/or following platinum-based chemotherapy. Eligible patients must have previously untreated, histologically confirmed Stage III-IV epithelial ovarian (EOC), fallopian tube cancer (FTC), or primary peritoneal cancer (PPC) and be candidates for platinum-based chemotherapy. The primary purpose of the study is to demonstrate if avelumab given as single agent in the maintenance setting following frontline chemotherapy or in combination with carboplatin/paclitaxel is superior to platinum-based chemotherapy alone followed by observation in this population of newly diagnosed ovarian cancer patients.
The purpose of this study is to confirm that the pharmacokinetics of ibrutinib in pediatric participants is consistent with that in adults (part 1) and to assess efficacy (event-free survival [EFS]) of ibrutinib in combination with rituximab, ifosfamide, carboplatin, and etoposide (RICE) or rituximab, vincristine, ifosfamide, carboplatin, and idarubicin (RVICI) background therapy compared to RICE or RVICI background therapy alone (part 2).
Multi-center, International, Prospective, Non comparative, Non randomized, Open label. 5,000 patients to be enrolled approximately worldwide. The objective of this registry is to collect safety and clinical performance post market data related to the procedure and follow-up of the Sorin Group aortic valve devices in accordance with the Instructions for Use (IFU). This observational global registry is intended to collect data without requiring any deviation from the standard of care and IFU in each participating center. The participating centers shall include those patients that have provided their informed consent to participate in this registry in accordance with the local applicable regulations.
This randomized, double-blind, placebo-controlled, parallel group study will evaluate the efficacy and safety of crenezumab versus placebo in participants with prodromal to mild AD. Participants will be randomized 1:1 to receive either intravenous (IV) infusion of crenezumab or placebo every 4 weeks (Q4W) for 100 weeks. The final efficacy and safety assessment will be performed 52 weeks after the last crenezumab dose. Participants will then have the option to enter the Open Label Extension (OLE) study if eligible. Participants who do not enter the OLE study will have additional follow-up visits at 16 and 52 weeks after the last dose, primarily for safety and also for limited efficacy assessments.
The purpose of this study is to assess long-term safety data of GED-0301 for a period of up to 208 weeks in adult subjects (i.e., ≥ 18 years of age) who participated in the core Phase 3 GED-0301-CD-002 and GED-0301-CD-003 studies and adolescent subjects (i.e., 12 to 17 years of age) who participated in the core Phase 3 GED-0301-CD-003 study. Although all subjects will receive active treatment, this study is double-blinded for the entire 208 weeks for the purpose of preserving the blind of the subject's treatment allocation in the initial, core Phase 3 GED-0301 study. The GED-0301-CD-003 trial was not initiated; see detailed description.
The purpose of this study is to assess whether copanlisib in combination with standard immunochemotherapy (rituximab in combination with bendamustine [R-B] and rituximab in combination with a 4 drug combination of cyclophosphamide, doxorubicin, vincristine and prednisone/prednisolone [R-CHOP]) is effective and safe, compared with placebo in combination with standard immunochemotherapy (R-B or R-CHOP) in patients with relapsed iNHL who have received at least one, but at most three, lines of treatment, including rituximab-based immunochemotherapy and alkylating agents.
The purpose of study EP0073 is to assess the long-term safety, tolerability, and efficacy during 5 years of treatment with the drug UCB0942 in patients with highly drug-resistant focal epilepsy. Also, the effects of UCB0942 on the patient's quality of life will be explored.
