There are about 6461 clinical studies being (or have been) conducted in Russian Federation. 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.
Helicobacter pylori is a common bacterial infection. It can lead to severe stomach problems, including stomach cancer. Researchers want to look at samples of the bacteria. These H. pylori strains will be taken from chronically infected people. They want to identify the genetic and epigenetic differences in H. pylori strains. This could help predict which people who get infected with the bacteria will get stomach cancer. This could lead to the cancer being detected earlier. It could also mean less people get stomach cancer. Objectives: To study genetic variations of H. pylori strains based on samples from chronically infected people. To identify the features of strains that might lead to severe stomach problems or stomach cancer. Eligibility: People ages 30-70 years who need an upper endoscopy or who were recently diagnosed with stomach cancer Design: Participants will be screened by the doctor who does their procedure and a study nurse. Participants who have endoscopy will have ~6 biopsies removed. These are tissue samples. They are about the size of a grain of rice. Participants will allow the study team to access reports from their stomach exam. Participants with stomach cancer will donate some of the tissue that will be removed during their clinical care. They will allow the study team to access reports of their surgery. They will also allow them to access the microscope slides of their stomach.
The main purpose of this study is to evaluate clinical efficacy of bismuth tripotassium dicitrate (De-Nol) in combination with pantoprazole versus pantoprazole monotherapy in subjects with NSAID-induced gastropathy in 14±2 days of treatment.
The main purpose of this study is to evaluate the efficacy of the study drug known as lanabecestat in participants with mild Alzheimer's disease (AD) dementia.
A Long-term Follow-up Study for Cardiac Safety in the Patients with HER2 Positive Early or Locally Advanced Breast Cancer Who Have Completed the SB3-G31-BC
The purpose of this study is to monitor ongoing safety in participants with ulcerative colitis (UC) and Crohn's disease (CD) and to provide access to vedolizumab for qualifying participants who, in the opinion of the investigator, continue to derive benefit from vedolizumab and for whom continued treatment with vedolizumab is desired because there is no other comparable product available or the participant may be expected to develop worsening of disease if they were to modify treatment.
This study is in two parts and will evaluate the safety, tolerability and efficacy of escalating single intravenous (IV) doses of ocrelizumab compared with placebo in combination with methotrexate in participants with moderate to severe RA. Part 1 is the dose-escalation study, at one of the following dose levels of ocrelizumab [400, 1000, 1500, and 2000 milligrams (mg)]. In Part 2, participants will be randomized to explore tolerability and efficacy of doses which have been shown to be tolerated in Part 1.
This is a Phase 3, open-label, international, multi-center, efficacy, and safety study of avelumab in combination with and/or following platinum-based chemotherapy. Eligible patients must have previously untreated, histologically confirmed Stage III-IV epithelial ovarian (EOC), fallopian tube cancer (FTC), or primary peritoneal cancer (PPC) and be candidates for platinum-based chemotherapy. The primary purpose of the study is to demonstrate if avelumab given as single agent in the maintenance setting following frontline chemotherapy or in combination with carboplatin/paclitaxel is superior to platinum-based chemotherapy alone followed by observation in this population of newly diagnosed ovarian cancer patients.
The purpose of this study is to assess whether TAB08 may be beneficial compared to placebo in patients with active Systemic Lupus Erythematosus, not adequately controlled with current concomitant treatment. Secondary purpose is to assess efficacy, safety, pharmacokinetic and pharmacodynamic parameters in this study population.
The primary objectives of this study are to evaluate the effect of Elafibranor treatment compared to placebo on 1) histological improvement and 2) all-cause mortality and liver-related outcomes in patients with nonalcoholic steatohepatitis (NASH) and fibrosis.
The purpose of this study is to confirm that the pharmacokinetics of ibrutinib in pediatric participants is consistent with that in adults (part 1) and to assess efficacy (event-free survival [EFS]) of ibrutinib in combination with rituximab, ifosfamide, carboplatin, and etoposide (RICE) or rituximab, vincristine, ifosfamide, carboplatin, and idarubicin (RVICI) background therapy compared to RICE or RVICI background therapy alone (part 2).
