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 Phase III, randomised, controlled, 3-arm, multi-centre study of neoadjuvant osimertinib as monotherapy or in combination with chemotherapy, versus SoC chemotherapy alone, for the treatment of patients with resectable EGFRm Non-Small Cell Lung Cancer
The purpose of this study is to compare CHF 5993 with CHF 1535 in improving lung function, reducing moderate and severe COPD exacerbations, and other clinical efficacy and safety outcomes in the target subject population.
In the BP-CON-ESH study we are going to include and analyze treated hypertensive patients seen consecutively by the ESH Excellence Centres. Blood pressure will be measured as usually done in the office, but care will be adopted to make measurements highly standardized in all Centres. The primary goals will be to determine the global, regional and country rates of hypertension control in Europe. Other goals will be to identify global and regional factors associated with blood pressure control in different European regions. The results obtained in the BP-CON-ESH project will be used to refine treatment strategies for improvement of blood pressure control and will serve as a basis for assessing future changes and trends in Europe.
The purpose of this study is to demonstrate superiority of macitentan 75 milligrams (mg) in prolonging the time to the first clinical events committee (CEC)-adjudicated morbidity or mortality (M/M) event in participants with symptomatic pulmonary arterial hypertension (PAH) compared to macitentan 10 mg.
This is a Phase 2/3 study that comprises 5 substudies designed to evaluate the efficacy, safety, and tolerability of oral etrasimod as therapy in adult participants with moderately to severely active Crohn's disease (CD) who are refractory or intolerant to at least 1 of the current therapies for CD (ie, corticosteroids, immunosuppressants, or biologics). The overall duration of this study is up to 282 weeks, inclusive of the Screening Period, Treatment Period of up to 274 weeks (Induction, Extension or Maintenance, and Long-term Extension Periods), and the 4-Week Follow-Up Period for safety assessment.
This is an open-label, non-comparator, global, multi-center, long-term safety study for evaluating safety and tolerability of linerixibat in participants with cholestatic pruritus in primary biliary cholangitis (PBC) who participated in a prior clinical trial with linerixibat (BAT117123 [NCT01899703], 201000 GLIMMER [NCT02966834] (group 1) or 212620 GLISTEN [NCT00210418]) (group 2). All participants will receive open-label linerixibat for the duration of the study. The study duration is expected to last until the study's end or until linerixibat can be lawfully made available to participants. However, the total duration of study participation will vary by participant depending upon the time of entry relative to study end in their respective country.
The purpose of this randomized controlled trial is to compare clinical data and implant stability of immediately loaded TSIII Osstem implants with Sandblasted and Acid-etched (SA) surface versus implants with SA surface modified with pH buffering agent for the rehabilitation of single implant-supported crown.
A Phase 3b, open-label, single-arm, rollover study to evaluate the long-term safety of luspatercept, to the following participants: - Participants receiving luspatercept on a parent protocol at the time of their transition to the rollover study, who tolerate the protocol-prescribed regimen in the parent trial and, in the opinion of the investigator, may derive clinical benefit from continuing treatment with luspatercept - Participants in the follow-up phase previously treated with luspatercept or placebo in the parent protocol will continue into long-term post-treatment follow-up in the rollover study until the follow-up commitments are met - The study design is divided into the Transition Phase, Treatment Phase and Follow-up Phase. Participants will enter transition phase and depending on their background will enter either the treatment phase or the Long-term Post-treatment Follow-up (LTPTFU) phase - Transition Phase is defined as one Enrollment visit - Treatment Phase: For participants in luspatercept treatment the dose and schedule of luspatercept in this study will be the same as the last dose and schedule in the parent luspatercept study. This does not apply to participants that are in long-term follow-up from the parent protocol - Follow-up Phase includes: - 42 Day Safety Follow-up Visit - During the Safety Follow up, the participants will be followed for 42 days after the last dose of luspatercept, for the assessment of safety-related parameters and adverse event (AE) reporting - Long-term Post-treatment Follow-up (LTPTFU) Phase - Participants will be followed for overall survival every 6 months for at least 5 years from first dose of luspatercept in the parent protocol, or 3 years of post-treatment from last dose, whichever occurs later, or until death, withdrawal of consent, study termination, or until a subject is lost to follow-up. Participants will also be monitored for progression to AML or any malignancies/pre-malignancies. New anticancer or disease related therapies should be collected at the same time schedule Participants transitioning from a parent luspatercept study in post-treatment follow-up (safety or LTPTFU) will continue from the same equivalent point in this rollover study. The rollover study will be terminated, and relevant participants will discontinue from the study when all participants fulfill at least 5 years from the first dose of luspatercept in the parent protocol, or 3 years of post-treatment from last dose, whichever occurs later.
The concept of the "ischemic cascade" is generally accepted hypothesis, according to which whenever ischemia of the myocardium occurs there is a consequence of events, that always occur in a given order - diastolic dysfunction first, followed by systolic dysfunction, then changes on electrocardiogram (ECG) and finally chest pain sensation. The occurrence of every next stage of cascade means more severe ischemia and respectively - more severe myocardial damage. We propose that mechanical and electrical changes in the myocardium during ischemia appear simultaneously.
This study will evaluate the efficacy and safety of ocrelizumab ( Ocrevus®) compared with placebo in participants with primary progressive multiple sclerosis (PPMS), including participants later in their disease course. This study focuses on upper limit disability progression. This study will consist of the following phases: screening, double-blind treatment, follow-up 1 (FU1), an optional open-label extension (OLE), follow-up 2 (FU2), and B-cell monitoring (BCM).
