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 purpose of the study is to evaluate the efficacy of bifeprunox in the maintenance phase of schizophrenia compared to placebo.
The purpose of this study is to determine the safety and efficacy of Rabeprazole extended release (ER) 50 mg versus Esomeprazole 40 mg for healing and symptomatic relief among subjects with erosive gastroesophageal reflux disease (GERD).
A long term observational ocular safety study in adults who have received study medication (either active drug or placebo) in a phase II or III clinical study evaluating eltrombopag. The study will follow subjects for 2.5 years following their last ocular assessment on their prior treatment study (regardless of the therapeutic indication) and will describe long-term ocular safety with respect to changes in the lenses over time from all subjects.
The purpose of this study is to evaluate the effectiveness, safety, and tolerability of JNJ-28431754 compared with placebo in patients with type 2 diabetes.
The purpose of this extension trial was to further evaluate the safety and tolerability of oral cladribine in subjects who have previously completed treatment within Trial 25643 (CLARITY). This trial also explored clinical benefit of prolonged 192-week versus 96-week treatment.
Cumulative follow-up with HX575 epoetin alfa to prospectively monitor the incidence of relevant drug-related adverse events and EPO-related lack of efficacy among Chronic Kidney Disease (CKD) subjects receiving HX575 epoetin alfa i.v.
The purpose of this study is to show the efficacy and safety of formoterol for the maintenance treatment of patients with COPD compared with placebo in patients in Japan and in European countries during 12 weeks.
THAOS is a global, multi-center, longitudinal observational survey open to all patients with transthyretin amyloidosis (ATTR), including ATTR-PN (polyneuropathy), ATTR-CM (cardiomyopathy) and wild-type ATTR-CM. It is open-ended with a minimum duration of 10 years. Patients will be followed as long as they are able to participate. The principal aims of this outcome survey are to better understand and characterize the natural history of the disease by studying a large and heterogenous patient population. Survey data may be used to develop new treatment guidelines and recommendations, and to inform and educate clinicians about the management of this disease.
The trial will determine the value of adding bevacizumab to chemotherapy plus trastuzumab in patients with resected node-positive or high risk node-negative, HER2-positive breast cancer.
The primary purpose of program was to enable patients, currently receiving sorafenib (Nexavar) in a Bayer/Onyx sponsored clinical trial, to continue sorafenib treatment after their respective study had met its primary endpoint and/or had reached the end as defined in the original protocol. Patients were able to continue treatment until (i) the treating physician felt the patient was no longer benefiting from the treatment or (ii) the treatment becomes commercially available and reimbursed for the respective indication as applicable in the country in which the patient lived and the patient could obtain suitable amounts of drug for treatment through standard mechanisms of commercial availability (ie, there should be no interruption in the patient's treatment schedule when switching to commercially available product) or (iii) the patient could join a Post-Trial-Access Program, another study or can receive sorafenib through any other mechanism (e.g. local access program) in accordance with local legal and compliance rules, with no cost to the patient with respect to sorafenib. An additional objective was the assessment of the safety of Nexavar or Nexavar combination treatment.
