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 aim of this clinical trial is to investigate the change in endometrial composition during the window of implantation following intrauterine administration of PBMC immunomodulated with IFNt. Patients seeking assisted reproductive therapy will be invited to participate. Two endometrial biopsies will be obtained from each patient during mid-secretory phase of two consecutive menstrual cycles. The first biopsy will be obtained one month before the intervention, and the second one - a day after intrauterine administration of the tested cell treatment which will take place the following month. Immunohistochemistry analysis of the cell composition of the endometrium will be performed.
The goal of this clinical trial is to test the effect of modulated specialised immune cells isolated from the patients' own blood when administered to the uterus before embryo transfer on the IVF outcome (implantation, pregnancy and live birth rates). To achieve this, blood will be obtained from eligible participants. Target cells will be isolated and incubated with the tested modulator for 24h, and returned to the uterine cavity 1 day prior to embryo transfer. Researchers will compare the reproductive outcome of the tested intervention to that of a control group who will not receive the investigated cell treatment prior to embryo transfer.
The purpose of the present interventional study is to assess the changes in the therapeutic response, ocular manifestations of Graves' orbitopathy and quality of life during the first year after orbital radiotherapy. The main questions it aim to answer are: 1. How effective is orbital radiotherapy used as first- or second-line treatment in patients with Graves' orbitopathy? 2. How does the quality of life changes after orbital radiotherapy? Participants have active moderate-to-severe Graves' orbitopathy and are treated with low dose fractionated orbital radiotherapy for two weeks. During the follow-up period they undergo regular ocular examinations and fill out a disease-specific questionnaire.
This is a Phase III open-label study to assess if camizestrant improves outcomes compared to standard endocrine therapy in patients with ER+/HER2 - early breast cancer with intermediate or high risk for disease recurrence who completed definitive locoregional therapy (with or without chemotherapy) and standard adjuvant endocrine therapy (ET) for at least 2 years and up to 5 years. The planned duration of treatment in either arm of the study is 60 months.
The purpose of this study is to evaluate the safety and tolerability of Ruxolitinib cream in participants with Prurigo Nodularis (PN).
This is a first in human (FIH), multi-center, dose-finding, and dose-escalation Phase I clinical study of RO7565020 to investigate the safety and tolerability and to characterize the pharmacokinetics and pharmacodynamics following single and/or multiple doses of RO7565020 in healthy participants and/or virologically suppressed participants with chronic hepatitis B (CHB).
This study will assess the efficacy and safety of dexpramipexole as an adjunctive oral therapy in participants with inadequately controlled asthma with an eosinophilic phenotype and a history of asthma exacerbations.
Functional constipation (FC) is a common healthcare problem in children of all ages, potentially due to genetic predisposition, inadequate fiber and fluid intake, and immobility. Currently, there are no pharmacological therapies approved for the treatment of FC. This study will assess adverse events and change in disease activity with linaclotide therapy in participants with FC. Linaclotide is an approved drug being developed for the treatment of FC in pediatric patients who meet modified Rome IV criteria for childhood FC. In Part 1 of this study, participants are placed in 3 groups, which occur consecutively. Each group receives a different dosage of linaclotide. In Part 2 of the study, participants will be randomly assigned to receive either linaclotide or placebo. There is a 1 in 2 chance that participants will be assigned to placebo. Approximately 30 pediatric participants 6 months to less than 2 years of age with FC will be enrolled in the study at about 25 sites worldwide. Participants will receive oral solution of linaclotide prepared from capsule by parent/guardian once daily for 4 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care (due to study procedures). Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
The purpose of this study is to evaluate if milvexian is at least as effective as apixaban for reducing the risk of the composite stroke and non-central nervous system (CNS) systemic embolism.
The purpose of this study is to evaluate that milvexian is superior to placebo, in addition to standard-of-care, in reducing the risk of major adverse cardiovascular event (MACE) (the composite of cardiovascular [CV] death, myocardial infarction [MI], and ischemic stroke).
