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.
The primary objective of this study is to evaluate the long-term safety and tolerability of peginterferon beta-1a (BIIB017) in participants originally treated in Study 105MS301 (NCT00906399) who continue peginterferon beta-1a treatment. The secondary objective of this study is to describe long-term multiple sclerosis (MS) outcomes in participants originally treated in Study 105MS301 (NCT00906399) who continue peginterferon beta-1a treatment.
Demonstrate the efficacy of High Intensity Focused Ultrasound in the treatment of the breast fibroadenoma.
This double-blind, placebo-controlled study will evaluate the benefit of first-line maintenance erlotinib (Tarceva) versus erlotinib at the time of disease progression in participants with advanced NSCLC who have not progressed following 4 cycles of platinum based-chemotherapy and whose tumor does not harbor an epidermal growth factor receptor (EGFR)-activating mutation. Participants will be randomized to receive either erlotinib 150 milligrams (mg) orally (PO) once daily or placebo. Participants who progress on placebo will receive erlotinib 150 mg PO once daily as second-line therapy, and those who progress on erlotinib may switch to a non-investigational, second-line chemotherapy. Treatments will continue until disease progression, death, or unacceptable toxicity. Participants may also be entered into a final Survival Follow-Up (SFU) period upon treatment discontinuation.
This is a phase III multicenter, randomized, double-blind, placebo-controlled, combination and component, two-period, incomplete block design cross-over study using GSK573719/GW642444. The primary objective is to evaluate lung function and exercise endurance time after 12 weeks of once-daily administration of GSK573719/GW642444 Inhalation Powder (125/25mcg and 62.5/25mcg), GSK573719 Inhalation Powder (125mcg and 62.5mcg), GW642444 Inhalation Powder 25 mcg and placebo delivered by a Novel dry powder inhaler (Novel DPI)
Main Study (CACZ885M2301): The purpose of the pivotal phase of this trial was to test the hypothesis that canakinumab treatment of patients with myocardial infarction (MI) at least one month prior to study entry and elevated hsCRP could prevent recurrent cardiovascular events. The purpose of the extension phase of the main study is to collect additional long-term safety data on continued exposure to canakinumab in patients who participated in the pivotal phase. Sub-study 1 (CACZ885M2301S1): The purpose of this sub-study was to evaluate the effect of quarterly subcutaneous canakinumab treatment for 24 months comparted with placebo on the carotid plaque burden measured by integrated vascular MRI in patients enrolled in the CACZ885M2301 study (CANTOS). Sub-study 2 (CACZ885M2301S2): The purpose of this CANTOS sub-study was to determine whether, in patients with type 2 diabetes participating in the CANTOS main study, canakinumab compared to placebo, on top of standard of care could increase insulin secretion and insulin sensitivity.
The purpose of this study was to determine whether asthma control and reduced bronchial responsiveness could be achieved and maintained at a lower dose of inhaled corticosteroids with ADVAIR DISKUS BID or FP BID in adult and adolescent patients with persistent asthma
This is a Phase 1b/2, multi-center, open-label, dose escalation (in 2 different dosing schedules [1 and 2]) and dose-confirmation study of eribulin administered in combination with capecitabine.
The purpose of this study is to investigate the efficacy of a treatment with TMC435 in combination with peginterferon alfa-2a and ribavirin in patients who did not clear their hepatitis C infection with peginterferon alfa-2a and ribavirin alone within a previous trial conducted by Tibotec, or who participated in Tibotec trials in which antivirals directed against hepatitis C virus (HCV) were evaluated for short periods of time.
The purpose of this study is to explore the safety, tolerability, and potential clinical efficacy of JNJ 40411813 in schizophrenic patients.
The purpose of this study is to evaluate the efficacy of Pixantrone + Rituximab compared to Gemcitabine + Rituximab in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), or follicular grade 3 lymphoma.
