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.
Goals: To explore the association of probability of pregnancy with certain prognostic factors in patients undergoing assisted reproductive technology in Russian population according to international and national guidelines.
Despite good progress in the management of patients with atrial fibrillation (AF), this arrhythmia remains one of the major causes of stroke, heart failure, sudden death, and cardiovascular morbidity in the world. Furthermore, the number of patients with AF is predicted to rise steply in the coming years. Even if the amount of antiarrhythmic drugs (AAD) is constantly increasing, there is a group of patients who has AF, resistant to AAD therapy. In such cases they are being offered alternative minimally invasive procedures, such as catheter or thoracoscopic ablation. With the discovery that AF often is initiated and maintained by electrical instability inside and around the pulmonary veins (PV) catheter and thoracoscopic ablation are now widely accepted invasive strategies to cure AF. Even though the results of both of the procedures are very promising in treating patients with paroxysmal AF, the decision making process, which approach should be used in patients with persistant or LSPAF, is still very controversial. According to 2016 ESC Guidelines for the management of atrial fibrillation developed in collaboration with EACTS, catheter or surgical ablation should be considered in patients with symptomatic persistent or long-standing persistent (LSP) AF refractory to AAD therapy to improve symptoms, considering patient choice, benefit and risk, supported by an AF Heart Team (IIaC). Since, there is no actual evidence base, which approach is more effective and save in patients with persistant and LSP AF, the aim of the investigator's study is to evaluate the results of both of the approaches in such group of patients.
A study to find out whether olaparib is safe and well tolerated when administered to children and adolescents with solid tumours.
The reason for this study is to determine the long-term efficacy and safety of the study drug mirikizumab in participants with Crohn's disease.
Primary objective of this open label, two-arm, multicenter, multinational, randomized trial is to compare anti-leukemic activity of allogeneic stem cell transplantation for patients with acute leukemia in complete remission between a 10/10 HLA matched unrelated donor and a haploidentical donor. The hypothesis: Haploidentical stem cell transplantation with post cyclophosphamide induces a stronger anti-leukemic activity in comparison to 10/10 HLA matched unrelated donor and reduces the risk of relapse at 2 years after stem cell transplantation by 10%.
Hypothesis. Regular using of Class 1 below-knee graduated compression stockings (RAL GZ 387 standard) compared to the absence of elastic compression will reduce the risk of clinically significant varicose veins recurrence at 12 months after endovenous thermal ablation of the great saphenous vein and elimination of varicose tributaries.
The gold standard of colorectal examination is colonoscopy. One of the main purposes of colonoscopy is detecting bowel neoplasms. Right now there are several methods the bowel preparation for the colonoscopy. Several factors can affect the quality of the bowel preparation, such as the kind of oral laxative, the time after its intake and the diet followed in the days before colonoscopy. In this randomized clinical trial the investigators aimed to compare the safety and efficiency of two low-volume laxatives for bowel preparation: potassium, magnesium and sodium sulphates-based laxative Eziclen (IPSEN, France) and Macrogol-3350 + Sodium Sulfate + Potassium Chloride+ Sodium Chloride + Ascorbic Acid-based and Sodium Ascorbate-based Moviprep (Nordgine B.V., The Netherlands)
This study is being done to see how well two drugs (enfortumab vedotin and pembrolizumab) work together to treat patients with urothelial cancer. The study will compare these drugs to other drugs that are usually used to treat this cancer (standard of care). The patients in this study will have cancer that has spread from their urinary system to other parts of their body.
This is a phase 1, open-label, non-comparative, multicenter clinical study to evaluate the safety, tolerability, and pharmacokinetics of ceftolozane/tazobactam (MK-7625A) in pediatric participants with nosocomial pneumonia (NP).
The purpose of this study is to evaluate safety and short-term oncological efficacy of the NanoKnife Irreversible Electroporation System for localised prostate cancer. Irreversible electroporation (IRE) is the method of focal treatment for prostate cancer, which is already proven by FDA as method of the surgical ablation of soft tissue. It has not received clearance for the therapy or treatment of any specific disease or condition.
