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 multi-center event-driven study in non-dialysis (ND) participants with anemia associated with chronic kidney disease (CKD) is to evaluate the safety and efficacy of daprodustat compared to darbepoetin alfa.
The primary objective of this study is to compare the performance of SUPRAFLEX to that of XIENCE in an all-comers patient population with symptomatic ischemic heart disease. The patients will be followed through 3 years for major clinical events.
The main purpose of this study is to assess the efficacy and safety of BT595 in adult subjects with chronic ITP. The primary objective of this study is to determine the rate of subjects with a response. A response is defined as a platelet count of ≥30×10^9/L and at least a 2 fold increase of the baseline count, confirmed on at least 2 separate occasions at least 7 days apart, and the absence of bleeding. The secondary objectives of this study, in addition to further efficacy assessments, are to evaluate the safety of BT595.
The primary purpose of the study is to evaluate the efficacy of BIIB059 (litifilimab) in reducing disease activity in participants with systemic lupus erythematosus (SLE) with active cutaneous manifestations and joint involvement (Part A), and in participants with active cutaneous lupus erythematosus (CLE) (Subacute cutaneous lupus erythematosus (SCLE) or chronic CLE, including discoid lupus erythematosus (DLE)) with or without systemic manifestations (Part B). The secondary objective is to evaluate additional efficacy parameters of BIIB059 in reducing SLE/CLE disease activity, pharmacokinetic parameters, safety and tolerability of BIIB059 (Parts A and B).
This is a multicenter, Phase II, randomized, double-blind, placebo-controlled, active comparator (Cohort 1 only), parallel-group, dose-ranging study to evaluate the efficacy and safety of GDC-0853 in participants with moderate to severe active RA and an inadequate response to previous methotrexate (MTX) therapy (Cohort 1) or MTX and tumor necrosis factor (TNF) therapy who may have also had exposure to no more than one non-TNF inhibitor biologic (Cohort 2).
This study is designed to evaluate the efficacy and safety of tofacitinib modified release formulation (11mg QD) versus tofacitinib modified release formulation plus continued methotrexate treatment in subjects with moderate to severe rheumatoid arthritis who are insufficiently responding to their stable dose of methotrexate treatment.
This open label extension study will give an opportunity to the participants that have responded to the treatment with Pegylated-Interferon Alfa-2a (PEG-INF) or Roferon-A in prior clinical studies NO15753 (NCT00003542) for Renal Cell Carcinoma, NO15764 (NCT number not available) and NO16006 (NCT02736721) for Chronic Myelogenous Leukemia, and NO16007 (NCT number not available) for Malignant Melanoma.
A randomised, double blind, parallel group, multicentre study yo compare the pharmacokinetics, pharmacokinetics, safety and efficacy of SAIT101 versus MabThera® versus Rituxan® in patients with rheumatoid arthritis.
To determine the safety and descriptive efficacy of dalbavancin for the treatment of acute bacterial skin and skin structure infections in children, aged birth to 17 years (inclusive), known or suspected to be caused by susceptible Gram-positive organisms, including methicillin-resistant strains of Staphylococcus aureus.
An interventional Phase 4 open-label, randomized, controlled, parallel-group, multi-country study in participants with psoriatic arthritis (PsA) consisting of 2 parts: Part 1 (Day 1 up to Week 16) is designed to compare the achievement of minimal disease activity (MDA) between participants randomized to either adalimumab in combination with methotrexate (MTX) or MTX alone escalated to the highest recommended or tolerable dose; Part 2 (Week 16 through Week 32) is designed to evaluate the maintenance or achievement of MDA on 4 different treatment regimens using adalimumab and/or MTX, with participant allocation based on the initial randomized treatment and achievement of MDA in Part 1, and with rescue treatment option.
