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 double-blind, double-dummy study will evaluate the safety and efficacy of ocrelizumab compared with fingolimod in children and adolescents with relapsing-remitting multiple sclerosis aged between 10 and < 18 years over a duration of at least 96 weeks.
The purpose of this research study is to determine whether the study drug, EDP1815, is safe and effective in the treatment of atopic dermatitis compared with placebo. The study will look at different doses of the study drug, and whether there are differences when the drug is given once daily or twice daily.
This study will look at the efficacy and safety of trastuzumab deruxtecan (T-DXd) in a neoadjuvant setting, in high-risk, HER2-positive early non-metastatic breast cancer.
This study will evaluate the pharmacokinetics (PK), safety, and tolerability of a single oral dose of zibotentan in patients with moderate hepatic and moderate renal impairment in comparison to a matched healthy control group.
The main objective of Part 1 is to evaluate the safety and tolerability of bemarituzumab plus 5-fluorouracil, leucovorin, and oxaliplatin (mFOLFOX6) and nivolumab. The main objective Part 2 is to compare efficacy of bemarituzumab plus chemotherapy (mFOLFOX6 or capecitabine combined with oxaliplatin (CAPOX)) and nivolumab to placebo plus chemotherapy (mFOLFOX6 or CAPOX) and nivolumab as assessed by overall survival.
The primary objective for this study is to evaluate the effect of adjunctive valbenazine versus placebo on symptoms of schizophrenia in participants who have inadequate response to antipsychotic treatment.
This is a parallel, treatment, Phase 2, double-blind, 2 arm, 12-week Proof of Concept (PoC) study with 2 staggered cohorts (2 arms in each cohort) that is designed to assess the efficacy, safety, and tolerability of rilzabrutinib in adult participants (aged 18-70 years) with moderate-to-severe asthma who are not well controlled on ICS/LABA therapy. Study treatment includes investigational medicinal product (IMP) (rilzabrutinib or placebo) added-on to a background therapy of ICS/LABA (fluticasone/salmeterol [non-investigational medicinal product], standardized at screening). Background therapy of ICS/LABA will be withdrawn during the 12week randomized treatment period and resumed at the end of the IMP treatment period, as outlined below: - Screening period (4 weeks) - Randomized IMP treatment period (12 weeks ± 3 days) - Background therapy stabilization phase (4 weeks) - Background therapy withdrawal phase (4-5 weeks) - No background therapy phase (3-4 weeks) - Post IMP treatment safety follow-up period (4 weeks ± 3 days)
This is an interventional, randomized, parallel group, treatment, Phase 3b/4, double blind, 2-arm study to assess the effect of dupilumab compared to standard of care therapy on preventing or slowing the rate of lung function decline in adult patients with uncontrolled moderate to severe asthma. The estimated duration is 4±1 weeks of screening and run-in period, followed by a 3-year double blinded treatment period. There will be a post-treatment follow-up (FU) period up to 12 weeks.
This study will be conducted to assess the efficacy, pharmacodynamic (PD), safety, tolerability, and immunogenicity of RGB -14- P compared to US-licensed Prolia® in participants with postmenopausal osteoporosis, in a comparative manner.
The purpose of the study is to evaluate the efficacy of olezarsen as compared to placebo on the percent change in fasting triglycerides (TG) from baseline.
