There are about 2681 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.
Study RNLC3132 is a Phase 3, randomized, double-blind, placebo-controlled, multicenter study to assess the efficacy and safety of rifaximin SSD-40mg IR for the delay of the first episode of overt hepatic encephalopathy (OHE) decompensation in liver cirrhosis, defined by the presence of medically controlled ascites.
This study will assess the safety, efficacy and immune response following the sequential treatment of GlaxoSmithKline's (GSK) ASO compound (GSK3228836) and CHB-TI (GSK3528869A) in participants 18 to 65 years stable on NA treatment for CHB. The aim is to quantify the efficacy of sequential therapy as well as to determine an added value of sequential therapy over GSK3228836 therapy in CHB patients treated with NAs. In addition, the study will assess the effect of different treatment durations of GSK3228836 (12 or 24 weeks) prior to initiating GSK3528869A treatment.
This is a study designed to evaluate efficacy and safety of Tezepelumab in reducing oral corticosteroid use in adult patients with severe asthma who are receiving oral corticosteroids with or without additional asthma controller medications.
This is a Phase IIIb, single-arm, multicenter, OLE study. Participants receiving ocrelizumab as an investigational medicinal product (IMP) in a Roche sponsored Parent study who continue to receive ocrelizumab or are in safety follow-up at the time of the closure of their respective Parent study (WA21092, WA21093 or WA25046) are eligible for enrollment in this extension study. Participants who will continue ocrelizumab treatment will receive IMP based on the dosage and administration received at the time of rollover from the Parent study.
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 is open to adults with bronchiectasis. People can join the study if they produce sputum and have a history of flare-ups (also called exacerbations). The purpose of this study is to find out whether a medicine called BI 1291583 helps people with bronchiectasis. Participants are put into 4 groups randomly, which means by chance. Participants in groups 1, 2, and 3 get different doses of BI 1291583. Participants in group 4 get placebo. Placebo tablets look like BI 1291583 tablets, but do not contain any medicine. Participants take the tablets once a day. Participants are in the study for between 6 months and 1 year. During this time, they visit the study site about 10 times and get about 5 phone calls from the site staff. The doctors document when participants experience flare-ups during the study. The time to the first flare-ups is compared between the treatment groups. Doctors also regularly check participants' health and take note of any unwanted effects.
Phase 2 study of the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and efficacy of KPL-404 in subjects with moderate to severe Rheumatoid Arthritis.
