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 purpose of this Phase 1b double-blind, randomized, placebo-controlled trial is to evaluate the safety, tolerability, pharmacokinetic (PK), and biological effect of MSC2364447C administered for 4 weeks in systemic lupus erythematosus subjects (SLE).
The purpose of this study is to determine whether etrasimod (APD334) is a safe and effective treatment for ulcerative colitis after 52 weeks of treatment.
This is a multicenter, open label study to assess the safety and pharmacokinetics of YKP3089 as adjunctive therapy in subjects with partial onset seizures. Initially, subjects taking phenytoin or phenobarbital will be enrolled followed by additional subjects taking anti-epileptic drugs (AED) other than phenytoin and phenobarbital to further investigate long-term safety.
Sirukumab is a fully human anti-interleukin-6 (IL-6) immunoglobulin G1-kappa with a high affinity and specificity for binding to the human IL-6 molecule that may have therapeutic benefit in the treatment of giant cell arteritis (GCA) by interruption of multiple pathogenic pathways. Sirukumab inhibits IL-6-mediated signal transducer and activator of transcription 3 (STAT3) phosphorylation, resulting in the inhibition of the biological effect of IL-6. This study will evaluate the efficacy and safety of sirukumab to characterize the benefit-to-risk profile of sirukumab in the treatment of active GCA. The study will be conducted in 2 distinct parts (Part A and Part B) and consists of the following phases: Screening phase, Part A: 52-week double-blind treatment phase, Part B: 104-week extension phase with the option to receive open-label sirukumab based on disease status and a 16-week follow-up phase if applicable. Approximately 204 subjects with a diagnosis of GCA and active disease within 6 weeks of baseline will be randomized into Part A, the 52-week double-blind treatment phase, to receive one of two doses of sirukumab or placebo, each in addition to a pre-specified prednisone taper. The efficacy and safety of sirukumab in sustaining remission will be assessed at Week 52. Subjects completing Part A of the study will be eligible to enter Part B, the 104-week extension phase, designed to investigate the long-term maintenance of remission and safety following cessation of sirukumab treatment and to assess long-term corticosteroid use. Subjects with active GCA at the end of Part A or those with new onset of GCA flare during the first 52 weeks of Part B will be eligible to receive open-label sirukumab. Subjects will need to have follow-up safety evaluations for at least 16 weeks after receiving the last dose of study drug, applicable only for those who are withdrawn prematurely from the study or whose open-label sirukumab treatment in Part B completes after Week 88.
The purpose of this study is to evaluate the safety and efficacy of omadacycline as compared to moxifloxacin in the treatment of adults with community-acquired bacterial pneumonia.
The purpose of this study is to evaluate the long-term safety and efficacy of RPC1063 in participants with moderately to severely active ulcerative colitis. Only those participants who have previously participated in a trial of RPC1063, being either RPC01-3101 or completed at least 1 year of the open-label period of RPC01-202 will be eligible.
This Phase 3 study was designed to demonstrate the net benefit of sotagliflozin versus placebo in patients with Type 1 Diabetes (T1D).
The purpose of this study is to compare the long-term joint safety and efficacy (pain relief) of the investigational study drug, tanezumab compared to non-steroidal anti inflammatory drugs (NSAIDs) in subjects with osteoarthritis of the hips or knees.
The objective of the study is to examine the effect of Nifedipine, applied intra-anally through our drug delivery device, on rectal pain severity in anal fissure patients that are being managed with conservative treatment.
A placebo-controlled, randomized, double-blind, parallel group, phase III multicenter study in subjects recently hospitalized for ACS and with the appropriate genetic profile. Subjects will provide informed consent before any study-specific procedures are performed. Subject enrollment may begin in the hospital and will continue following release from the hospital. Screening procedures may be performed at the time of the index ACS event or anytime thereafter, with the condition that randomization must occur within the mandated window (4-12 weeks after the index event). Subjects will be assessed based on their medical history. Those who are likely to qualify will undergo Genotype Assay testing to evaluate genetic determination for the presence of AA genotype.
