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.
Atopic dermatitis (AD) is a skin condition that may cause a rash and itching due to inflammation of the skin. Therapies spread over the skin may not be enough to control the AD in trial participants who require systemic anti-inflammatory treatment. This study evaluates the dosing flexibility of upadacitinib in adult participants with moderate to severe AD. Adverse events and change in the disease activity will be assessed. Upadacitinib is an approved drug for the treatment of moderate to severe/active immune-mediated inflammatory diseases such as rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, ulcerative colitis (UC), Crohn's Disease (CD), and AD. The study is comprised of a 35-day Screening Period, a 12-week double-blind period and a 12-week single-blind period. During the double-blind period, participants are placed in 1 of 2 groups, called treatment arms and will be randomized in a 1:1 ratio to receive upadacitinib. At 12 weeks during the single blind period, participants will be blinded to the upadacitinib dose based on their EASI response and reassigned to in 1 of 4 arms. After the last study visit, there is a 30-day follow-up visit. Approximately 454 adult participants ages 18 to 64 with moderate to severe AD who are candidates for systemic therapy will be enrolled at up to 160 sites worldwide. The study is comprised of a 12-week double-blind period, followed by a 12-week single-blind period. Participants will receive upadacitinib oral tablets once daily for up to 24 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.
This is a multicenter, randomized, placebo controlled study to evaluate the efficacy and safety of ABX464 given at 25 or 50 mg QD in inducing clinical remission in subjects with moderately to severely active ulcerative colitis who have inadequate response, no response, a loss of response, or an intolerance to either conventional therapies [corticosteroids, immunosuppressant (i.e. azathioprine, 6-mercaptopurine, methotrexate)] and/or advanced therapies [biologics (TNF inhibitors, anti-integrins, anti-IL-23), and/or S1P receptor modulators, and/or JAK inhibitors].

This is an open-label, multicenter extension trial to evaluate the long-term safety of KVD900 in patients who are 12 years or older with HAE type I or II.
This is a Phase 3, open-label, randomized, clinical trial evaluating the efficacy and safety of gedatolisib plus fulvestrant with or without palbociclib for the treatment of patients with locally advanced or metastatic HR+/HER2- breast cancer following progression on or after CDK4/6 and aromatase inhibitor therapy.
The primary objective is to characterize the efficacy TEV-48574 in adult participants with IBD (moderate to severe Ulcerative Colitis (UC) or Crohn's Disease (CD)) as assessed by induction of clinical remission (UC) and endoscopic response (CD) at week 14. Secondary objectives: - To evaluate the efficacy and dose response of the 2 different dose regimens as assessed by multiple standard measures - To evaluate the safety and tolerability of the 2 different dose regimens - To evaluate the immunogenicity of the 2 different dose regimens The study will consist of a screening period of up to 6 weeks (42 days), a 14-week treatment period, and a 4-week follow-up period.
This is a Phase 1/2, multicenter study with an open-label dose escalation followed by a randomized placebo controlled and double-blind phase of SLN124 in adult patients with Polycythemia Vera (PV) to assess the safety, tolerability, efficacy, pharmacokinetic (PK), and Pharmacodynamic (PD) response of SLN124.
This is a research study to evaluate the efficacy and safety of the investigational drug Mitiperstat (AZD4831) in adult patients with chronic obstructive pulmonary disease.
This is a single group, Phase 2, long-term extension study for treatment. The purpose of this study is to characterize the safety and efficacy of amlitelimab in treated adult participants with moderate to severe AD who have previously been enrolled in an amlitelimab clinical trial. Visits during the on-treatment period will be at Week 0, 1, 2, 4 and every 4 weeks (Q4W) thereafter. If remote visits are considered appropriate for participants instead of clinic visits at the timepoints indicated in the schedule of activities (SoA) participants/caregivers/legally authorized representatives (LAR) are allowed to perform participant-injections at home according to the schedule of dosing. This decision is at the discretion of the investigator.
Researchers are looking for a better way to treat people who have chronic kidney disease (CKD), a progressive decrease in the kidneys' ability to work properly. In people with CKD, the kidneys do not remove wastes and extra fluid from the blood as well as they should. High blood pressure makes it more likely that the CKD gets worse. The study treatment BAY3283142 is under development for treating CKD. It activates a protein called soluble guanylate cyclase (sGC) that generates cGMP - a molecule that relaxes blood vessels and is thought to have beneficial effects in CKD. The participants do not benefit from this study. However, the study will provide information on how to use BAY3283142 in subsequent studies in people with CKD. As many people with CKD do also suffer from high blood pressure, this study is done in people with mild to moderate high blood pressure to safeguard the use of BAY3283142 in people with CKD in later studies. The main purpose of this study is to learn how safe different single and multiple doses of the study treatment BAY3283142 are compared to placebo in male and female participants (after menopause) with mild to moderate high blood pressure. A placebo is a treatment that looks like a medicine but does not have any medicine in it. To answer this, the researchers will compare the number of participants who have medical problems after taking BAY3283142 to those treated with placebo. Doctors keep track of all medical problems that happen in studies, even if they do not think they might be related to the study treatments. Dependent on the treatment group, the participants will either take BAY3283142 or placebo as tablet once or twice a day. Patients will take one dose for 6 days and will then be switched to a higher dose for additional 6 days. In summary, three different dose combinations consisting of two different doses each will be tested. Participants will be in the study for up to 7 weeks, including 12 treatment days (6 per dose step). They will stay in-house for 17 days starting two days before intake of the study treatment. In addition, one visit before and one visit after the in-house phase to the study site is planned. During the study, the study team will: - Check vital signs - Take blood and urine samples - Examine the participants' heart health using electrocardiogram (ECG)
