There are about 2655 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 study will evaluate the clinical safety and the performance of the BTL-754 device (equipped with the 754-4 applicator) for reduction of facial wrinkles by the means of laser skin resurfacing treatment.
This Phase 3 study is a randomized, observer-blind study of aQIV (an MF59-adjuvanted quadrivalent influenza vaccine) compared with a non-adjuvanted quadrivalent influenza vaccine (QIV) in adults ≥65 years of age. The aim of the study is to evaluate aQIV compared with QIV in the prevention of reverse transcription-polymerase chain reaction (RT-PCR)-confirmed influenza A and/or B in subjects ≥65 years of age.
This is a study to compare the efficacy, safety and immunogenicity of AVT05 versus EU-Simponi® in combination with methotrexate (MTX) in subjects with moderate to severe rheumatoid arthritis (RA). The study will consist of up to 4-week Screening Period, a 48-week Treatment Period, and a 4-week Safety Follow-up Period.
The primary objective of this study is to evaluate the efficacy of TV-44749 in adult patients with schizophrenia. A key secondary objective is to further evaluate the efficacy of TV-44749 based on additional parameters in adult patients with schizophrenia. A secondary objective is to evaluate the safety and tolerability of TV-44749 in adult patients with schizophrenia Another secondary objective of this study is to evaluate the efficacy of TV-44749 from baseline to endpoint in Period 1 in adult patients with schizophrenia. Total study duration is up to 61 weeks, and treatment duration is up to 56 weeks, with weekly visits during the first 8 weeks and then monthly in-clinic visits with weekly calls during the remainder of the treatment period.
This study will look at how much weight participants will lose and how much blood sugar control they achieve from the start to the end of the study. The weight loss in participants taking the investigational high dose of semaglutide will be compared to the weight loss in people taking "dummy" medicine and a lower dose of semaglutide. In addition to taking the medicine, participants will have talks with study staff about healthy food choices and how to be more physically active. Participants will either get semaglutide or "dummy" medicine. Which treatment participants get is decided by chance. Participants are more likely (4 out of 5) to get semaglutide than the "dummy" medicine. The study medicine will be injected briefly, under skin, with a thin needle, typically in the stomach, thighs, or upper arms. After receiving first dose, the dose of semaglutide will be gradually increased until reaching the target dose. The study will last for about 1.5 years.

Participants are more likely (4 out of 5) to get semaglutide than the "dummy" medicine. The study medicine will be injected briefly, under skin, with a thin needle, typically in the stomach, thighs, or upper arms. In the first part of the study, participants will get one injection once a week until they reach the planned dose. The second part of the study, which might last a couple of months, is a transition period, where participant will get three injections, taken right after each other, once a week. The duration of the study intervention (trial product and lifestyle intervention) will be 72 weeks followed by a 9-week follow-up period without study interventions.
This is a study to demonstrate the clinical efficacy and safety of the nanobody® sonelokimab administered subcutaneously (sc) compared with placebo in the treatment of adult participants with active psoriatic arthritis. The study includes adalimumab treatment as an active reference arm.
This is a Phase 2, randomized, double-blind, placebo-controlled 2 parallel-arm study to assess the effect on serum neurofilament light chain (sNfL), safety and tolerability of oral SAR443820 compared to placebo in male and female participants aged 18 to 60 years with relapsing-remitting multiple sclerosis (RRMS), secondary progressive multiple sclerosis (SPMS) (relapsing or non-relapsing), or primary progressive multiple sclerosis (PPMS) followed by an open-label long-term extension period. The total study duration is approximately 100 weeks and includes the following: 4-week screening period 48-week double-blind treatment period (Part A) 48-week open-label long-term extension period (Part B)
Izokibep is a potent and selective inhibitor of interleukin (IL)-17A that is being developed for treatment of psoriatic arthritis (PsA). This study will evaluate the efficacy of izokibep in subjects with PsA.
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 compares upadacitinib to dupilumab in adolescent and adult participants with moderate to severe AD who have inadequate response to systemic therapies. Adverse events and change in the disease activity will be assessed. Upadacitinib and dupilumab are approved drugs for the treatment of moderate to severe atopic dermatitis (AD). The study is comprised of a 35-day Screening Period, a 16-week treatment period 1 and a 16-week treatment period 2. During period 1, participants are randomly assigned in 1 of 2 groups, called treatment arms to receive upadacitinib Dose A or dupilumab. In Period 2, participants will receive upadacitinib Dose A or Dose B. Approximately 880 adolescent and adult participants ages 12 to 64 with moderate to severe AD who are candidates for systemic therapy will be enrolled at up to 330 sites worldwide. Participants will receive upadacitinib oral tablets once daily or dupilumab as per its label for 32 weeks and followed for 30 days. There may be higher treatment burden for participants in this trial compared to their standard of care . 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.
