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.
To assess persistence of CT-P13 in patients with Rheumatoid Diseases (Rheumatoid arthritis [RA], ankylosing spondylitis [AS], and psoriatic arthritis [PsA]) who are naïve to biologics or are switching from stable Remicade to CT-P13. The main objectives of the study are: - To evaluate real-life drug persistence in RA, AS, and PsA patients who are either initiated with CT-P13 as their first biologic, or who are switched from stable Remicade - To characterise the patient populations and drug usage patterns of RA, AS, and PsA patients who are either initiated with CT-P13 as their first biologic, or who are switched from stable Remicade - To assess the safety of CT-P13 in RA, AS, and PsA patients who are either initiated with CT-P13 as their first biologic, or who are switched from stable Remicade for up to 2 years
This is a Phase 3, double-blind, randomized, placebo-controlled, multicenter study to determine the efficacy and safety of luspatercept (ACE-536) plus Best supportive care (BSC) versus placebo plus BSC in adults who require regular red blood cell transfusion due to (β)-thalassemia. The study is divided into the following periods: - Historical Period, - Screening/Run-in Period, - Double-blind Treatment Period (48 weeks), - Double-blind Long-term Treatment Period, (at the investigator's discretion an additional 48 weeks), - Open-Label Phase post unblinding and upon Data Monitoring Committee positive recommendation - Post-treatment Follow-up Period
This randomized active-controlled multicenter Phase III open-label study will evaluate and compare between treatment groups the efficacy of alectinib versus chemotherapy in participants with ALK-positive advanced NSCLC who were previously treated with chemotherapy and crizotinib, as measured by investigator-assessed progression-free survival (PFS) and to evaluate and compare between treatment groups the central nervous system (CNS) objective response rate (C-ORR) in participants with measurable CNS metastases at baseline, as assessed by an Independent Review Committee (IRC).
This study will evaluate the efficacy and safety of QVA149 (110/50 μg o.d.) vs tiotropium (18 µg o.d.) + salmeterol/fluticasone propionate FDC (50/500 µg b.i.d.) in patients with moderate to severe COPD
This is a phase 2, open-label, multicenter study to explore the efficacy and safety of oral GED- 0301 in subjects with active UC, defined as a modified Mayo score (MMS) ≥ 4 and ≤ 9 and a Mayo endoscopic subscore≥ 2. Approximately 40 subjects will be enrolled using an Interactive Voice Response System (IVRS) or an Interactive Web Response System (IWRS) to receive open-label, oral GED-0301 160 mg for duration of 52 week treatment. Enrollment of subjects with previous exposure to TNF-α blockers will be limited to approximately 15 subjects. The number of subjects with extensive colitis is targeted to comprise approximately 50% of the entire study population.
This is a multicenter, randomized, double-blind study of the efficacy and safety of iclaprim compared to vancomycin for the treatment of skin and skin structure infections.
The study will evaluate the efficacy and safety of ITI-007 adjunctive to lithium or valproate in a randomized, double-blind, parallel-group, placebo-controlled, multi-center study in patients diagnosed with Bipolar I or Bipolar II disorder having a major depressive episode.
The purpose of this study is to assess safety and effectiveness of the p64 Flow Modulation Device.
RE-COVERY is a large, multi-national, multi-center observational study based on new data collection. The study will enroll and characterize patients within 30 days of being diagnosed with an acute DVT and/or PE. The study has two main objectives. Objective 1 will characterize the DVT / PE patient population. All patients with a DVT and/or PE will be enrolled for cross-sectional characterization of the VTE patient population. Objective 2 will compare the safety and effectiveness of dabigatran etexilate regimens for treatment of VTE in comparison to VKA regimens. Patients treated with dabigatran etexilate or VKA will be followed up for the occurrence of outcome events for up to one year.
A Phase III, Randomized, Observer-Blind, Controlled, Multicenter Clinical Study to Evaluate the Efficacy, Safety and Immunogenicity of an MF59-Adjuvanted Quadrivalent Influenza Vaccine Compared to Non-influenza Vaccine Comparator in Adults ≥ 65 Years of Age.
