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.
Phase III study to compare the efficacy and safety of the novel monopegylated interferon alpha 2b AOP2014 versus Hydroxyurea (the current licensed therapy for this disease). One year treatment of patients with polycythemia vera. Objective is to demonstrate non-inferiority of AOP2014 vs. HU in terms of disease response rate in both HU naïve and currently treated patients, diagnosed with Polycythemia Vera. Response is measured as normalisation of key lab parameters as well as normalized spleen size.
The primary objective is to assess the long-term safety of dupilumab administered in adult participants with atopic dermatitis (AD). The secondary objective of the study is to assess the immunogenicity of dupilumab in adult participants with AD, in the context of re-treatment, and to monitor efficacy parameters associated with long-term treatment. Optional Sub-Study: The primary objective of the sub-study is to assess the safety of the new dupilumab drug product in adult patients with AD after switching from the current dupilumab drug product. The secondary objectives of the sub-study are to evaluate systemic exposure and immunogenicity of the new dupilumab drug product in adult patients with AD.
The purpose of this study is to determine whether Benralizumab reduces the number of asthma exacerbations in patients who remain uncontrolled on medium doses of ICS-LABA.
A six month study of ACP-001, a long-acting growth hormone product, versus standard human growth hormone therapy. ACP-001 will be given once-a-week, standard human growth hormone (hGH) will be given on a daily basis. The primary aim is to demonstrate safety, pharmacokinetics and pharmacodynamics over a period of six months. A secondary objective is the comparison of height velocity (HV) of the ACP-001 treated groups to the daily hGH treatment group.
Efficacy of Fluticasone/Formoterol in COPD Treatment. The Effect study.
To continue the evaluation of the safety and efficacy of BAX 855 for prophylaxis and treatment of bleeding episodes in adult and pediatric previously treated patients (PTPs) aged ≤ 75 years of age with severe hemophilia A.
The primary objective of this study is to compare the efficacy, safety, and tolerability of tenofovir alafenamide (TAF) versus tenofovir disoproxil fumarate (TDF) in treatment-naive and treatment-experienced adults with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B virus (HBV) infection.
This is a randomized, double-blind, parallel group, multicentre clinical study to evaluate the efficacy, safety, pharmacokinetics and immunogenicity of SB2 compared to Remicade in subjects with moderate to severe Rheumatoid Arthritis (RA) despite Methotrexate (MTX) therapy.
The purpose of this study is to assess the efficacy of selumetinib in combination with docetaxel (75mg/m2) vs placebo in combination with docetaxel (75mg/m2) in patients with locally advance or metastatic NSCLCs that harbor mutations of KRAS. This study will also assess the PK, safety, patient reported outcomes (PRO) and tolerability profile of the selumetinib/docetaxel combination, compared to placebo in combination with docetaxel
This trial is conducted in Africa, Asia, Europe and South America. The aim of the trial is to evaluate efficacy and safety of semaglutide once-weekly versus sitagliptin once-daily as add-on to metformin and/or TZD (thiazolidinedione) in subjects with type 2 diabetes.
