There are about 1832 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.
The subjects will be enrolled and assigned to a single study group. They will be required to complete two treatment visits and come for a biopsy procedure.
A single-blinded hybrid effectiveness-implementation trial (Type II), that both evaluates the intervention outcomes (clinical and service use outcomes) through patient-randomization in the implementation sites, as well as evaluates the implementation strategy chosen for the intervention and its impact on implementation outcomes (e.g. adoption, fidelity, acceptability and maintenance (continued implementation) of the intervention).
This is a randomized, double-blind, dose-finding, placebo-controlled, parallel group, multicenter, phase II study to evaluate the efficacy, safety, and popPK of three different doses of OMT-28 given once daily versus placebo in patients with persistent AF.
To assess the efficacy of 30 mg of BAY1753011, with or without furosemide, versus furosemide alone in patients with heart failure and objective evidence of congestion.
The purpose of this study is to determine the efficacy of JNJ-70033093 in preventing total venous thromboembolism (VTE) events (proximal and/or distal deep vein thrombosis [DVT] [asymptomatic confirmed by venography assessment or objectively confirmed symptomatic], nonfatal pulmonary embolism [PE]), or any death during the treatment period.
International, Multicentre, Parallel-group, Randomised, Double-blind, Placebo-controlled, Phase III Study Evaluating the effect of Dapagliflozin on Exercise Capacity in Heart Failure Patients with Preserved Ejection Fraction (HFpEF)
Durvalumab or Placebo in Combination With Gemcitabine/Cisplatin in Patients With 1st Line Advanced Biliary Tract Cancer (TOPAZ-1)
The study will evaluate the efficacy, safety, and tolerability of 450 milligrams (mg) of Rapastinel, compared to 10 mg of Vortixetine and placebo in participants with major depressive disorder (MDD).
The purpose of this study is to evaluate the efficacy of treating participants with treatment-resistant depression (TRD) who have failed at least 2 (and no more than 6) prior antidepressant (AD) treatments in the current moderate to severe depressive episode with flexibly-dosed esketamine nasal spray plus a newly initiated oral standard-of-care AD compared with placebo nasal spray plus a newly-initiated standard-of-care oral AD, in achieving remission and staying relapse-free after remission.
This is a Phase 2 multicenter, double-blind, placebo-controlled, randomized, parallel-group trial to assess the efficacy and safety of 2 once-daily oral doses of IMU-838 (vidofludimus calcium), a small molecule inhibitor of dihydroorotate dehydrogenase (DHODH), 30 mg/day and 45 mg/day, in patients with RRMS and evidence of active disease. The trial consists of a screening period, a blinded 24-week main treatment period, and an optional initially blinded, then open-label extended treatment period of up to 9.5 years. About 40 centers are planned to participate in Romania, Bulgaria, Ukraine, and Poland; potential additional centers in Hungary and Croatia. In total, 195 patients are planned to be randomized 1:1:1 to treatment with 30 mg/day or 45 mg/day IMU-838, or placebo (65 patients each) in the main treatment period. During the extended treatment period, patients will be re-randomized such that patients previously on placebo will be re-randomized 1:1 to treatment with 30 g/day or 45 mg/day IMU-838, all other patients will be re-randomized to the same treatment they previously received.
