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 randomized, double-blind, placebo-controlled study will evaluate the safety and efficacy of RoActemra/Actemra (tocilizumab) in patients with ankylosing spondylitis (AS) who have failed treatment with non-steroidal anti-inflammatory drugs and are naïve to tumor necrsos factor (TNF) antagonist therapy. In Part 1 of the study, patients will be randomized to receive either RoActemra/Actemra 8 mg/kg intravenously (IV) or placebo every 4 weeks for 12 weeks. In Part 2, patients will be randomized to receive RoActemra at either 8 mg/kg or 4 mg/kg IV or placebo every 4 weeks for 24 weeks. The double-blind treatment period will be followed by open-label treatment with RoActemra/Actemra 8 mg/kg iv every 4 weeks until Week 208 for all patients. Anticipated time on study treatment is 208 weeks.
This randomized, double-blind, placebo-controlled study evaluated the safety and efficacy of tocilizumab (RoActemra/Actemra) in patients with ankylosing spondylitis (AS) who had an inadequate response to previous tumor necrosis factor (TNF) antagonist therapy. Patients were randomized to receive tocilizumab at a dose of either 8 mg/kg or 4 mg/kg intravenously (iv) or placebo every 4 weeks for 24 weeks. The double-blind treatment period was followed by open-label treatment with tocilizumab 8 mg/kg iv every 4 weeks until Week 104 for all patients. This study and all further clinical development of tocilizumab AS was halted after a review of 12-week data from Study NA22823, a randomized double-blind, placebo-controlled study in TNF antagonist naïve AS patients, failed to demonstrate efficacy.
The purpose of this study is to evaluate the safety and tolerability of PF-03049423 following multiple dose administration to subjects with ischemic stroke. The study will also evaluate the efficacy of PF-03049423, relative to placebo, in subjects with ischemic stroke following 90 days of therapy. The study will also explore the relationship between PF-03049423 concentration and blood pressure.
This was a multi-center, parallel, active comparator controlled, open-label, randomized (1:1) phase III study of single agent ofatumumab compared to single agent rituximab in subjects with rituximab-sensitive indolent B-cell non hodgkin lymphoma that has relapsed at least 6 months after completing treatment with single agent rituximab or a rituximab-containing regimen. Subjects must have attained a Complete Response or Partial Response to their last prior rituximab containing therapy lasting at least six months beyond the end of rituximab therapy. Subjects were to receive four weekly doses of single agent ofatumumab (1000 mg) or rituximab (375 mg/m2), followed by ofatumumab (1000 mg) or rituximab (375 mg/m2) every 2 months for four additional doses. Therefore, subjects were to receive a total of eight doses of anti-CD20 antibody over 9 months. Subjects were evaluated for response after completion of the first four doses of therapy, after six doses of therapy, and after completion of study therapy. Subjects were to be followed until the end of the designated follow-up period (total study duration of 200 weeks) or until they meet the withdrawal criteria. The primary objective of the study OMB157D 2303 was to demonstrate the efficacy of Arzerra based on the primary endpoint (Progression-free survival (PFS) as assessed by the IRC) in patients with Indolent B-cell Non-Hodgkin's Lymphoma Relapsed After Rituximab-Containing Regimen. The Independent Data Monitoring Committee (IDMC) met on November 22, 2015 and recommended the termination of the study due to futility (cut-off date = 12Jun2015). The IDMC reviewed analyses results for progression free survival (PFS), overall response rate (ORR), and overall survival (OS). Novartis accepted this recommendation and the study was closed. Final analysis was performed (cut-off date =19 Dec 2016). As the study was stopped for futility, the primary objective was not met and some secondary endpoints, supportive of primary objective (Duration of Response (DOR), time to next therapy, and pharmacokinetics) were removed as secondary end points.
The primary purpose of this study is to help answer if LY2127399 is safe and effective in the treatment of rheumatoid arthritis while on a background treatment of methotrexate. This study is comprised of 3 periods: Period 1: 52-week blinded treatment Period 2: additional 48-week unblinded treatment Period 3: 48-week post-treatment follow-up
The main objective of this study is to evaluate the long-term safety of CP-690,550 in patients being treated for moderate to severe chronic plaque psoriasis. This is an open label extension study available to patients who participated in one of the qualifying studies with CP-690,550 providing entry criteria is met.
Primary Objective: - Demonstrate the efficacy of Dronedarone in preventing major cardiovascular events (stroke, systemic arterial embolism, myocardial infarction or cardiovascular death) or unplanned cardiovascular hospitalization or death from any cause in patients with permanent Atrial Fibrillation [AF] and additional risk factors Secondary Objective: - Demonstrate the efficacy of Dronedarone in preventing cardiovascular death This was an event-driven study where a common study end date [CSED] was to be determined by Steering Committee based on the number of events (stroke, systemic arterial embolism, myocardial infarction or cardiovascular death).
This is an open-label study consisting of a screening period, a conversion/titration phase (Phase 1), an open-label treatment phase (Phase 2), and a follow-up period. The study will enroll new subjects (hereafter referred as "de novo" subjects) with schizophrenia, or bipolar I disorder, manic or mixed episode with or without psychotic features, and rollover subjects with schizophrenia from 31-09-266 (hereafter referred to as "Study 266"). All de novo subjects must enter the screening period of the study. Subjects who are screened and are not required to go through Phase 1 will complete a Phase 2 baseline visit prior to their participation in Phase 2. Study Design: Treatment, Single Group Assignment, Open Label, Active Control, Safety/Efficacy Study
The primary objective of this study is to evaluate the safety and tolerability of long term (6 months) armodafinil treatment as adjunctive therapy to mood-stabilizing medications in adults with bipolar I disorder.
This will be a multicenter, randomized, double-blind study designed to assess the efficacy, safety and tolerability of an oral Aripiprazole/Escitalopram combination therapy in participants with MDD who have demonstrated an incomplete response to a prospective trial of Escitalopram, and report a treatment history for the current MDD episode of an inadequate response to at least one and no more than three adequate trials of an approved antidepressant other than Escitalopram. An inadequate response is defined as less than a 50% reduction in depressive symptom severity as assessed by the participant's self-report on the Massachusetts General Hospital Antidepressant Treatment Response Questionnaire (ATRQ) and evaluated by the investigator as part of the participant's medical and psychiatric history. An adequate trial is defined as an antidepressant treatment for at least 6 weeks duration (or at least 3 weeks for combination treatments) at an approved dose as specified in the ATRQ.
