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 purpose of this study is to evaluate the efficacy of guselkumab treatment in participants with active psoriatic arthritis (PsA) axial disease by assessing reduction in axial symptoms and inflammation.
Cancer is a condition where cells in a specific part of body grow and reproduce uncontrollably. Non-small cell lung cancer (NSCLC) is a solid tumor, a disease in which cancer cells form in the tissues of the lung. The purpose of this study is to determine if telisotuzumab vedotin works better than docetaxel and to assess how safe telisotuzumab vedotin is in adult participants with NSCLC who have previously been treated. Change in disease activity and adverse events will be assessed. Telisotuzumab vedotin is an investigational drug being developed for the treatment of NSCLC. Participants will be randomly assigned a treatment of Teliso-V or Docetax at an 1:1 ratio. Each group receives intravenous (IV) infusion of telisotuzumab vedotin or IV infusion of docetaxel. Approximately 698 adult participants with c-Met overexpressing NSCLC will be enrolled in the study in approximately 250 sites worldwide. Participants will receive IV telisotuzumab vedotin every 2 weeks or docetaxel every 3 weeks until meeting study drug discontinuation criteria. 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.
Chronic lymphocytic leukemia (CLL) is the most common leukemia (cancer of blood cells). The purpose of this study is to assess retreatment with venetoclax-obinutuzumab (VenG) in participants previously treated with fixed duration first-line (IL) therapy of venetoclax in combination with an anti-CD20 antibody +/- X (where X is any additional drug). Adverse events and change in disease activity will be assessed. Venetoclax is an approved drug for the treatment of CLL. Study doctors put the participants in 1 of 2 groups, called cohorts, based on when symptoms of CLL came back after previous treatment in first-line. Approximately 75 adult participants with CLL who have been treated with venetoclax in combination with an anti-CD20 antibody +/- X will be enrolled in the study in approximately 60 sites worldwide. Participants will receive intravenous (IV) obinutuzumab + oral venetoclax (VenG) in 28-day cycles for a total of 6 cycles per cohort, followed by 6 to 18 cycles of venetoclax alone, for a total treatment of 12 to 24 cycles, depending on the cohort. 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.
In this study, researchers will learn more about a study drug called litifilimab (BIIB059) in participants with systemic lupus erythematosus (SLE). The study will focus on participants who have active disease and are already taking standard of care medications. These may include antimalarials, steroids, and immunosuppressants. The main objective of the study is to learn about the effect litifilimab has on lowering the activity of the disease. The main question researchers want to answer is: - How many participants have an improvement in their symptoms after 52 weeks of treatment? Researchers will answer this and other questions by measuring the symptoms of SLE over time using a variety of scoring tools. These include the SLE Responder Index (SRI), the Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2K), and the Patient Global Assessment - Visual Analog Scale (PGA-VAS). Researchers will also learn more about the safety of litifilimab. They will study how participants' immune systems respond to litifilimab. Additionally, they will measure the effect litifilimab and SLE have on the quality of life of participants using a group of questionnaires. The study will be done as follows: - After screening, participants will be randomized to receive either a high or low dose of litifilimab, or placebo. A placebo looks like the study drug but contains no real medicine. - All participants will receive either litifilimab or placebo as injections under the skin once every 4 weeks. The treatment period will last 52 weeks. Participants will continue to take their standard of care medications. - Neither the researchers nor the participants will know if the participants are receiving litifilimab or placebo. - There will be a follow-up safety period that lasts up to 24 weeks. - In total, participants will have up to 22 study visits. The total study duration for participants will be up to 80 weeks.
This is a global, open-label, randomized, 2-arm, Investigator's choice Phase 3 (Pivotal Stage) study to investigate the efficacy/performance and safety of NBTXR3/RT±cetuximab versus RT±cetuximab in treatment-naïve, platinum-ineligible, elderly participants with LA-HNSCC.
The purpose of this study is to evaluate the efficacy of guselkumab treatment in participants with active psoriatic arthritis (PsA) by assessing the reduction in signs and symptoms of PsA.
This is a phase 2, multicenter, randomized, double-blind, placebo-controlled, parallel-group study in patients with moderate to severe active ulcerative colitis.
This study evaluates either KRT-232 or TL-895 in treatment naïve patients with myelofibrosis (MF) The study will be conducted in 2 stages. Stage 1 will evaluate safety, tolerability, and efficacy of either KRT-232 (Arm 1) or TL-895 (Arm 2) in treatment naïve patients. Stage 2 will expand enrollment in Arm 1 and/or Arm 2 if expansion criteria is met.
The purpose of this study is evaluating the efficacy and safety of SC antifrolumab in adult patients with moderate -to-severe SLE despite receiving standard therapy
This is a long term safety study for patients who have completed a Novartis sponsored asciminib study and are judged by the investigator to benefit from continued treatment
