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.
ARGX-113-2009 is an operationally seamless 2-part, phase 2/3, prospective, global, multicenter, randomized, double-blinded, placebo-controlled study to investigate the efficacy, safety, tolerability, immunogenicity, participant-reported outcome measures (including those assessing participant QoL), PK, and PD of efgartigimod PH20 SC administered via subcutaneous (SC) injection in adult participants with moderate to severe BP. This study intends to demonstrate that efgartigimod is an effective and safe treatment for BP, providing participants with control of disease activity (CDA) and eventually remission while reducing their cumulative exposure to OCS. study will consist of 2 parts: - Part A of the study is a phase 2 evaluation that intends to provide proof of concept for the therapeutic activity of efgartigimod PH20 SC in participants with BP. - Part B of the study is a phase 3 evaluation that intends to confirm the results obtained from part A in a separate, larger group of participants with BP. An interim analysis will be performed during part A (on data obtained through week 26 for all Part A participants) to assess the primary endpoint and several secondary endpoints, confirm the appropriate sample size for part B of the study, and determine whether the efficacy results observed through week 26 of part A warrant continued study of efgartigimod PH20 SC for the treatment of participants with BP (futility analysis). Other than differences in main goals, endpoints, and statistical analyses, parts A and B are identical in schedule, structure, assessments, and conduct.
This Phase 3, multinational, single-arm, multicenter study will evaluate the efficacy and safety of UGN-102 as primary chemoablative therapy in patients with low grade intermediate risk non-muscle-invasive bladder cancer (LG IR NMIBC).
The purpose of this study is to assess the efficacy and safety of oral belzutifan (MK-6482) plus intravenous (IV) pembrolizumab (MK-3475) compared to placebo plus pembrolizumab, in the adjuvant treatment of Clear Cell Renal Cell Carcinoma (ccRCC) post nephrectomy. The primary study hypothesis is that belzutifan plus pembrolizumab is superior to placebo plus pembrolizumab with respect to disease-free survival (DFS).
The purpose of this study is to evaluate the efficacy, safety, pharmacokinetics (PK), and antidrug antibody (ADA) response for MEDI8897 in healthy late preterm and term infants who are 35 weeks or greater gestational age and entering their first RSV season.
This study will be a placebo-controlled, double-blind, randomized, phase 3 study in participants with Atherosclerotic Cardiovascular Disease (ASCVD) who are not adequately controlled despite maximally tolerated lipid-lowering therapy.
Study of efficacy, safety, tolerability and quality of life of inclisiran (KJX839) vs placebo, on top of ongoing individually optimized lipid-lowering therapy, in participants with hypercholesterolemia
A randomized, placebo-controlled study designed to evaluate the safety and efficacy of paltusotine (formerly CRN00808; an oral selective nonpeptide somatostatin receptor type 2 biased agonist) in subjects with non-pharmacologically treated acromegaly.
Study to evaluate the safety and efficacy of luvadaxistat compared with placebo on improving cognitive performance in participants with schizophrenia.
The purpose of this Proof of Concept (PoC) and Dose-finding (DF) basket study is to evaluate the efficacy and safety of orally administered Enpatoran over 24 weeks in systemic lupus erythematosus (SLE) and cutaneous lupus erythematosus (CLE; subacute cutaneous lupus erythematosus [SCLE] and/or discoid lupus erythematosus [DLE]) participants in a randomized, double-blind, placebo-controlled, parallel, adaptive and dose-ranging setting. Study Duration: 33 weeks Visit Frequency: every 2 or 4 weeks Enpatoran is not available through an expanded access program.
This is a study to understand if taking VTX002 daily as a tablet orally is safe and effective in participants diagnosed with moderate to severe ulcerative colitis (UC). Approximately 189 participants will take VTX002 Dose A, VTX002 Dose B, or matching placebo, once daily. The study consists of a 28-day Screening Period (to see if a participant qualifies for the study), a 13-week double-blind period (a participant receives either active Dose A, Dose B or Placebo), a Long-Term Extension (LTE) Treatment Period of up to 39 weeks, an Open-Label Extension (OLE) Treatment Period of up to 143 weeks, and a 2-week Follow-Up Period. The maximal duration of treatment including the Induction Period, LTE and OLE will be 36 months.
