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 randomized, double-blind, double-dummy, parallel-group study will evaluate the efficacy and safety of ocrelizumab in comparison with interferon beta-1a (Rebif) in participants with relapsing multiple sclerosis. Participants will be randomized to receive either ocrelizumab 600 mg or matching placebo intravenous (IV) as 300 mg infusions on Days 1 and 15 for the first dose and as a single infusion of 600 mg for all subsequent infusions every 24 weeks, with placebo injections matching interferon beta-1a SC three times per week; or interferon beta-1a 44 mcg SC injections three times per week (with placebo infusions matching ocrelizumab infusions every 24 weeks).
- The primary objective of this study was to characterize the pharmacokinetics (PK) of alglucosidase alfa manufactured at the 4000 L scale in participants who had a confirmed diagnosis of Pompe disease. - A secondary objective of this study was to evaluate and explore the relationship between anti-recombinant human acid alpha-glucosidase antibody titers and the PK of alglucosidase alfa.
The purpose of this Phase 3 study is to assess the pharmacokinetics of rVWF:rFVIII and rVWF, and to assess the safety and efficacy of rVWF:rFVIII and rVWF in the treatment of bleeding events in subjects with severe hereditary von Willebrand disease (VWD).
The primary objective of the study is assess the safety and tolerability of long-term epratuzumab treatment in subjects with Systemic Lupus Erythematosus (SLE)
This study will assess the safety and efficacy of two different doses and two different dose regimens of subcutaneous secukinumab in patients that have moderate to severe, chronic, plaque-type psoriasis.
This study is conducted to explore the safety and tolerability and plasma pharmacokinetics of NRL001 after single intra-anal dose of 1mL cream at increasing concentrations.
This is a non-interventional treatment Registry of Hereditary Angioedema (HAE) patients treated with C1 inhibitor, either plasma-derived (pdC1INH) or the recombinant human form (rhC1INH / Ruconest), to observe adverse events and insufficient efficacy, and to assess the immunological profile following single and repeated treatment with Ruconest.
The objective of this study was to evaluate the efficacy, safety, and tolerability of cariprazine relative to placebo for the treatment of participants with bipolar depression.
This study is being done to evaluate the efficacy and safety of asenapine as compared to placebo in preventing the recurrence of mood episodes after stabilization of an acute/manic mixed episode in participants with Bipolar 1 Disorder. After a Screening Period, each participant will receive open-label asenapine and matching placebo for 12 to 16 weeks. Participants who meet stabilization criteria may then be randomized into one of the two study arms (asenapine or matching placebo) to receive double-blind treatment for up to an additional 26-weeks.
The purpose of this trial is to assess whether dulaglutide can reduce major cardiovascular events and other serious outcomes in persons with type 2 diabetes, when added to their anti-hyperglycemic regimen.
