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 is a 24-week randomized, double-blind, placebo-controlled, parallel-group, multicenter study to evaluate the efficacy and safety of intranasal administration of 186 and 372 μg twice daily (BID) of OPN-375 in subjects with chronic rhinosinusitis (CS) with or without nasal polyps.
The aim of this study is to determine the efficacy of a virtual reality (VR) device in reducing injection pain and anxiety associated with local anesthesia in pediatric dental patients. The clinical trial is a randomized split-mouth assignment. Included patients are 8-12 years old requiring local anesthetic infiltration with conventional syringe (CS) for conservative treatment of two primary maxillary molars bilaterally. Eligible patients undergo two single-visit treatments after CFSS-DS measurement before each, whereas VR is allocated to either first or second local anesthesia procedure. Primary outcome measure will be pain felt during injection, reported by patient on visual analogue scale (VAS). Secondary outcome measures: self-reported anxiety during injection on FIS; pain-related behavior according to FLACC scale; heart-rate dynamics; patient preference to local anesthesia method - CS or CS+VR.
The purpose of this study is to evaluate the efficacy and safety of vortioxetine given as a single intravenous dose of 25 mg at initiation of an oral vortioxetine regimen of 10 mg/day for 7 days
The primary objective of this study is to assess the efficacy of fostamatinib in subjects with warm antibody autoimmune hemolytic anemia (wAIHA).
A Phase 3 study to evaluate efficacy, safety, and tolerability of ampreloxetine (TD-9855) in subjects with primary autonomic failures (MSA, PD, or PAF) and symptomatic nOH with up to 4 weeks of treatment.
This is a pharmacokinetics (PK), open-label, uncontrolled, multicenter phase II trial with age-staggered approach. The primary objective is to evaluate the PK profile of gadopiclenol in plasma following single IV injection of 0.05 mmol/kg body weight (BW) in pediatric population aged from 2 to 17 years undergoing CNS contrast-enhanced MRI (CNS cohort).
The purpose of this study is to assess the efficacy of ruxolitinib cream in adolescents and adults with atopic dermatitis (AD).
Multicenter, randomized, double-blind, parallel-group, placebo-controlled study to evaluate the efficacy and safety of anamorelin HCl. Approximately 316 patients with advanced NSCLC with cachexia will be randomized 1:1 to anamorelin HCl 100 mg or placebo, taken orally once daily (QD) for a total of 24 weeks. Patients will be instructed to take the study drug at least 1 hour before their first meal of the day
The purpose of the study is to assess the efficacy and safety of 4 doses of cenerimod versus placebo in adult subjects with systemic lupus erythematosus (SLE).
This study will collect data on bleeds and data related to quality of life in people with severe congenital (a disease existing from birth) haemophilia A and B, with or without inhibitors. The aim for the study is to look at the number of bleeds when on usual treatment for haemophilia. Participants will be asked to keep an electronic diary to track the number of bleeds and the treatment of their bleeds. Participants will be asked to wear an activity tracker on their wrist to capture their level of activity every day for up to 12 weeks. While taking part in this study, participants will keep getting their usual treatment as given to them by their doctor. All study visits at the clinic are done in the same way as the participants are used to. In the time between the participants' visits to the clinic, the study staff at the clinic may call or email the participant. The study will last for about 2½ years.
