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 objective of this study is to compare the effect of treatment with olpasiran, to placebo, on the risk for coronary heart disease death (CHD death), myocardial infarction, or urgent coronary revascularization in participants with atherosclerotic cardiovascular disease (ASCVD) and elevated Lipoprotein(a).
This study has 2 parts: First part is the main study and second part is the extension study. During the main study participants will receive 1 of 4 study medicines. If participants continue in the extension study, they will not receive any study medicine during the extension. The main study will look at how well CagriSema helps participants with excess body weight lose weight compared to a "dummy" medicine and 2 other medicines, cagrilintide and semaglutide. Participants will either get CagriSema, cagrilintide,semaglutide or "dummy" medicine. Which treatment participants get is decided by chance. They will take one injection once a week. The study medicine is injected briefly with a thin needle, typically in the stomach, thighs or upper arms. Extension study: After the main study, not all participants will continue in the extension study. The study staff will tell the participant if they will continue or not into the extension study. In the extension study we will look at what happens to the participant's body weight and diseases related to excess body weight after the participant stops taking the study medicine. The main study will last for about 1½ years and the extension study will last for another 2 years.
The purpose of this 20-week randomized double-blind study in patients with resistant hypertension (rHTN) is to evaluate the efficacy, safety, and tolerability, of different doses of XXB750 administered as subcutaneous (SC) injections, compared to placebo. Since all study participants will be patients with rHTN, all study treatments will be given on top of maximally tolerated background antihypertensive therapy recommended by international guidelines for treatment of HTN (i.e., a thiazide or a thiazide-like diuretic, an angiotensin converting enzyme inhibitor (ACEi) or an angiotensin receptor blocker (ARB), and a long-acting dihydropyridine calcium channel blocker (CCB).
Study to evaluate the efficacy, safety and tolerability of ponsegromab compared to placebo in patients with cancer, cachexia, and elevated GDF 15.
The purpose of this study is to evaluate the efficacy, including clinical remission of guselkumab subcutaneous (SC) induction compared to placebo in participants with moderately to severely active ulcerative colitis (UC).
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 research study to evaluate the efficacy and safety of the investigational drug Mitiperstat (AZD4831) in adult patients with chronic obstructive pulmonary disease.
This clinical study aims to assess the efficacy of TOTUM-854, a mix of 6 plant extracts, consumed twice a day on automated office blood pressure in subjects with moderately elevated blood pressure. The hypothesis is that TOTUM-854 is superior to placebo for decrease of automated office blood pressure after 12 weeks of consumption.
This is a Phase IIIb, multinational, multicenter, randomized, open-label study to evaluate patient preference of the fixed-dose combination of pertuzumab and trastuzumab for subcutaneous use (PH FDC SC) administration in the home setting compared with the hospital setting during the cross-over period of adjuvant treatment in participants with early or locally advanced/inflammatory human epidermal growth factor receptor 2-positive (HER2+) breast cancer.
The purpose of this study is to assess the clinical effect, the pharmacodynamics, the safety, and the pharmacokinetics of barzolvolimab (CDX-0159) in patients with Chronic Inducible Urticaria who remain symptomatic despite the use of H1-antihistamines.
