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 purpose of this multicenter, randomized, placebo-controlled and double-blind study is to evaluate the efficacy and safety of subcutaneous anifrolumab compared with placebo on the overall disease activity in participants with moderate to severe Idiopathic Inflammatory Myopathies (IIM) [polymyositis (PM) or dermatomyositis (DM)] while receiving standard of care (SoC) treatment.
Researchers are looking for a better way to treat people who have advanced non-small cell lung cancer (NSCLC) with specific genetic changes called human epidermal growth factor receptor 2 (HER2) mutations. Advanced NSCLC is a group of lung cancers that have spread to nearby tissues or to other parts of the body or that are unlikely to be cured or controlled with currently available treatments. HER2 is a protein that helps cells to grow and divide. A damage (also called mutation) to the building plans (genes) for this protein in cancer cells leads to a production of abnormal HER2 and therefore abnormal cell growth and division. The study treatment, BAY 2927088, is expected to block the mutated HER2 protein which may stop the spread of NSCLC. The main purpose of this study is to learn how well BAY 2927088 works and how safe it is compared with standard treatment, in participants who have advanced NSCLC with specific genetic changes called HER2 mutations. The study participants will receive one of the study treatments: - BAY 2927088 twice every day as a tablet by mouth, or - Standard treatment in cycles of 21 days via infusion ("drip") into the vein. The treatment will continue for as long as participants benefit from it without any severe side effects or until they or their doctor decide to stop the treatment. During the study, the doctors and their study team will: - take imaging scans, including CT, PET, MRI, and X-rays, of different parts of the body to study the spread of cancer - check the overall health of the participants by performing tests such as blood and urine tests, and checking - heart health using an electrocardiogram (ECG) - perform pregnancy tests for women - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatment.
This is a randomised, double-blind, parallel group, placebo-controlled Phase IIa study designed to evaluate the efficacy and safety of AZD7798 in participants with moderate to severe Crohn's disease.
The study is designed to evaluate the long-term safety and efficacy of GSK1070806 in participants with moderate-to severe atopic dermatitis, who have completed phase 2b parent GSK atopic dermatitis (AtD) study (NCT05999799).
This study is a retrospective study trying to find the predictive factors for medullary thyroid aggressiveness in terms of tumor metastasis and patients' survival.
The goal of this clinical trial is to evaluate two treatment strategies in patients with chronic atrial fibrillation and heart failure, who are eligible for atrial fibrillation ablation. Patients will be randomized to either atrial fibrillation ablation or to implantation of a pacemaker with conduction system pacing followed by atrioventricular node ablation. The effect of treatment allocation on total mortality, cardiovascular hospitalization and heart failure hospitalization will be compared.
The research study is being done to see if ziltivekimab can be used to treat people who were admitted to hospital because of a heart attack. Ziltivekimab might reduce development of heart disease, thereby preventing new heart attacks or strokes. Participants will either get ziltivekimab (active medicine) or placebo (a dummy medicine which has no effect on the body). Which treatment participants get is decided by chance. The chance of getting ziltivekimab or placebo is the same. Ziltivekimab is not yet approved in any country or region in the world. It is a new medicine that doctors cannot prescribe. The study will last for about 2 years.
This study aims to evaluate the efficacy and safety of subcutaneous (SC) anifrolumab versus placebo in adult participants with cutaneous lupus erythematosus (CLE).
The improvement or preservation of quality of life (QoL) is one of the three pillars of the European Union (EU) Mission on Cancer, which underpins the needs of patients from cancer diagnosis throughout treatment, survivorship, and advanced terminal stages. Clinical studies and real-world data show that the use of Patient Reported Outcome Measures (PROMs) for QoL assessment in routine oncology practice has positive effects on patient wellbeing and healthcare resource utilization. However, full implementation of PROMs is not yet part of standard of care and is not adequately considered in cancer policies and programs. A comprehensive tool incorporating the perspective of patients at different stages of the disease trajectory and widely applicable across Europe is still lacking. The European Oncology Quality of Life Toolkit (EUonQoL-Kit) is a unified patient-centred tool for the assessment of QoL, developed from preferences and priorities of people with past or current cancer experience. The EUonQoL-Kit includes three electronic questionnaires, specifically designed for different disease phases (patients in active treatment, survivors, and patients in palliative care), available in both static and dynamic (Computer Adaptive Testing, CAT) versions and in several European languages. This is a multicentre observational study, with the following aims: - The primary aim is to perform the psychometric validation of the EUonQoL-Kit. - Secondary aims are to assess its acceptability, to validate the static and dynamic versions against each other, and to provide estimates of QoL across European countries. The EUonQoL-Kit will be administered to a sample of patients from 45 European cancer centres. The sample will include patients in active treatment (group A), survivors (group B), and patients in Palliative Care (group C). Each centre will recruit 100 patients (40 from group A, 30 from group B, 30 from group C), for an overall sample size of 4,500 patients (at least 4,000 patients are assumed to be enrolled, due to an expected lower recruitment rate of 10-15%). Three sub-samples of patients (each corresponding to 10% of the total sample for each centre) will fill in an additional questionnaire: - FACT-G (Functional Assessment of Cancer Therapy - General) and EQ-5D-5L (5-level European Quality of Life Five Dimension), to test concurrent validity. - Live-CAT version, to validate the static and dynamic versions against each other. - EUonQoL-Kit, at least 1 hour after the first completion, to assess test-retest reliability.
The study will aim to find out if the drug andexanet alfa is safe and effective in preventing major bleeding during urgent surgery or invasive procedures. The study will compare the use of andexanet alfa to the usual care given at the study center.
