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 IV, randomized, double-blind, parallel-group, multiple-dose, active comparator, multicenter clinical study to evaluate the pharmacokinetics, efficacy, safety, and immunogenicity of SB5 versus Humira in subjects with moderate to severe chronic plaque psoriasis.
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)
The objective of this 3-month observational study was to assess, in 2827 adults, the benefit of NP alone or as adjunctive or maintenance care in mild acne, or as adjunctive care in subjects with moderate acne.
This study will evaluate the clinical safety and the performance of the BTL-785F system for non-invasive treatment of facial wrinkles. The study is a multicenter single-arm, open-label, interventional study. The subjects will be enrolled and assigned into one experimental study arm. The subjects will be required to complete four (4) treatment visits and two follow-up visits.
Rheumatoid arthritis (RA) affects 1 percent of the population worldwide and up to 40 percent of patients don't respond to current treatments. MBS2320, the drug being tested in this trial, represents a new approach to treating RA, with the potential not only to reduce levels of inflammation but to also directly prevent bone damage. The aim of this project is to test the safety, tolerability and efficacy of MBS2320 in patients with RA in combination with an existing treatment, methotrexate. Approximately 224 participants with moderate to severe active RA who have not responded to treatment with Methotrexate will be enrolled from around 45 to 55 sites around the world. Participants will be randomly assigned to receive 1 of 3 doses of MBS2320 (5 mg, 20 mg, or 40 mg) or placebo (a "dummy" drug). The maximum duration of study participation for a participant will be 22 weeks, which consists of a Screening Period of up to 4 weeks, Treatment Period of 12 weeks, and a Follow-up Period of 6 weeks. Participants on the study will be asked to attend the hospital or clinic for regular visits during which they will have planned study assessments to evaluate the effectiveness, tolerability and safety of the study drug.
The primary objective of this study is to characterize the safety and tolerability of MK-6194 following multiple doses among participants with moderate to severe atopic dermatitis who are unresponsive to other therapies.
The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called Nirmatrelvir/Ritonavir) for the possible treatment of COVID-19. Patients with COVID-19 who have more difficulty in fighting against infections have a higher chance of severe illness. Such patients may benefit from longer treatment durations compared to the standard treatment regimen. The study is seeking participants who: - Have a confirmed COVID-19 infection - Are Immunocompromised - Experience onset of signs/symptoms attributable to the current COVID-19 infection within 5 days prior to screening and ≥1 signs/symptoms attributable to COVID-19 present on the day of randomization. In addition, this study will also evaluate the efficacy and safety of a second treatment course of nirmatrelvir/ritonavir in people who experience that their COVID-19 is flaring up within 14 days of having taken a 5-day treatment course of nirmatrelvir/ritonavir. For this group, the study is seeking participants who: - Have a confirmed COVID-19 infection - Experience a worsening of signs/symptoms after completing an initial 5-day course of nirmatrelvir/ritonavir - The worsening of COVID-19 symptoms must occur within 14 days after completion of the initial 5-day course of nirmatrelvir/ritonavir - Are Immunocompromised - Experience onset of signs/symptoms attributable to the current COVID-19 infection within 48 hours prior to screening and ≥1 signs/symptoms attributable to COVID-19 present on the day of randomization. All participants will be taking the study medicine for either 5, 10, or 15 days. The study medication will be taken by mouth 2 times a day. Participants will take part in this study for about 24 weeks. The first dose of study medication is taken at the study site and the rest at home. Selected participants will need to visit the study site at least 10 times during the study.
The purpose of the study is to obtain pharmacokinetics, safety and tolerability data after single administrations of CHF6001 in subjects with mild, moderate and severe renal impairment as well as healthy volunteers under the same setting.
This is a randomized, blinded, placebo-controlled, dose-ranging Phase 1b study of the safety, PK, and antiviral activity of ABI-H3733 in treatment-naïve or off-treatment chronic Hepatitis B virus (cHBV) subjects that are Hepatitis B e antigen (HBeAg) positive or negative. The study will enroll up to 5 sequential cohorts of 10 subjects each, for a total of up to 50 subjects, randomized 8:2 to receive ABI-H3733 or placebo.
