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.
Primary Biliary Cholangitis (PBC) is a serious, life-threatening, bile acid related liver disease of unknown cause. Without treatment, it frequently progresses to liver fibrosis and eventual cirrhosis requiring liver transplantation or resulting in death. The investigational drug, Obeticholic Acid (OCA) is a modified bile acid and FXR agonist that is derived from the primary human bile acid chenodeoxycholic acid. The key mechanisms of action of OCA, including its choleretic, anti-inflammatory, and anti-fibrotic properties, underlie its hepatoprotective effects and result in attenuation of injury and improved liver function in a cholestatic liver disease such as PBC. The study will assess the effect of OCA compared to placebo, combined with stable standard care, on clinical outcomes in PBC participants.
The purpose of this study is to evaluate the effects of Ceftaroline Fosamil versus Vancomycin plus Aztreonam in treatment of patients with complicated bacterial skin and soft tissue infections.
The vaccine contains humanized recombinant antigen (EGF - Epithelial Growth Factor) and an adjuvant. The antibodies induced by vaccination will react with circulating EGF leading to removal of EGF from the circulation. As a result, binding to its target EGF-Receptor is prevented. Blocking of EGF-Receptor is preventing activation and stimulation of proliferation of tumour cell. A Phase 3 clinical trial on the EGF vaccine is ongoing in Cuba. The result from previous studies demonstrated positive correlation between extended survival and immune response against the vaccination in the late-stage NSCLC patients' age below 60 with improved quality of life. The purpose of this international Phase 3 trial is to determine whether the recombinant human EGF cancer vaccine is safe, immunogenic and effective in the treatment of stage IV NSCLC patients who are positive in the selective EGF biomarker and wild type EGF-Receptor compared to standard treatment and supportive care.
The purpose of this study is to evaluate the safety and efficacy of oral Pyridorin 300 mg BID in reducing the rate of progression of nephropathy due to type 2 diabetes mellitus.
This two-part, part 1: open-label extension (OLE) and part 2: safety monitoring (SM) study will examine the efficacy and safety of continued etrolizumab treatment in moderate to severe ulcerative colitis (UC) participants previously enrolled in etrolizumab Phase II/III studies. Participants with moderate to severe UC who were enrolled in the Phase II OLE study (GA27927 [NCT01461317]) or the Phase III studies (GA28948 [NCT02163759], GA28949 [NCT02171429], GA28950 [NCT02100696], GA29102 [NCT02165215], and GA29103 [NCT02136069]) were included. Participants from the Phase II OLE study or the Phase III studies who are not eligible or willing to receive etrolizumab in the OLE-SM study, and who have completed the 12-week safety follow-up period will be enrolled in Part 2. Part 1 of OLE-SM will continue for up to 9 years after the first participant is enrolled into the study. Following Part 1, participants will enter Part 2 for a period of 92 weeks.
This is a sub-study of the OSKIRA-4 study, (D4300C0004, NCT01264770) to explore alternative and more sensitive modalities for measuring the beneficial effects of syk inhibition with fostamatinib in patients with active RA. This MRI sub-study was reported later than the main study due to recruitment delays at specialist imaging sites and so is registered and presented entirely separately to the main study results. This study will investigate the impact of treatment on joint activity and damage by assessing synovitis, osteitis, bone erosions and joint space narrowing.
The purpose of this study is to support selection of an appropriate safe and efficacious dose for study in further development.
The primary objective of this study is to obtain long term safety data of ataluren in male participants with nonsense mutation dystrophinopathy (who participated and completed a previous Phase 3 study of ataluren [PTC124-GD-020-DMD {NCT01826487}]) to augment the overall safety database. Screening and baseline procedures are structured to avoid a gap in treatment between the double-blind study (PTC124-GD-020-DMD) and this extension study. This study may be further extended by amendment until either ataluren becomes commercially available or the clinical development of ataluren in duchenne muscular dystrophy (DMD) is discontinued.
This is a multicenter, double-blind, Phase 2b, long-term extension (LTE) to the ADDRESS II core trial (EMR 700461-023) (NCT01972568), to evaluate long-term safety and tolerability of atacicept in participants with systemic lupus erythematosus (SLE). Participants who completed the 24-week core study ADDRESS II core study (NCT01972568) and thus not met any of the discontinuation criteria were invited to enter this long-term extension (LTE) study NCT02070978.
This was a multinational, multicenter, randomized, open-label study to confirm and expand the efficacy, safety and tolerability evidence of 48 hours intravenous infusion of serelaxin (30 micrograms/kg/day) when added to Standard of Care (SoC) in patients admitted to hospital for Acute Heart Failure (AHF).
