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.
Left atrial appendage (LAA) occlude devices are used for over ten years. According to current data efficiency and safety of this approach at least comparable with pharmacological prevention of stroke in patients with non-valvular atrial fibrillation. However, to date, LAA occluder implantation is not recommended as an alternative for conservative therapy and reserved for patients with contraindications for oral anticoagulants only. In the same time, long-term follow-up of patients enrolled in clinical trials and data from registries showed that LAA occlude device implantation as an alternative to oral anticoagulation could reduce drug load, decrease complexity and cost of treatment and thus improve patients' quality of life, and potentially may reduce the risk of death. The aim of our study is to investigate the risk of all-cause death, stroke, and bleedings in patients with LAA occluder implanted as an alternative to anticoagulant therapy. Three hundred patients with atrial fibrillation will undergo LAA occluder implantation. For LAA occluder sizing transesophageal echocardiography (TEE), CT and LAA angiography will be performed. The follow-up period will be 36 months. The incidence of all-cause death, stroke, bleeding BARC≥2, device-related complications and QOL will be investigated. The patients will be followed in the clinic at three and six months, and then at 12, 24 and 36 months, the telephone calls for getting information about endpoints events will be done. Additional in clinic visits will be scheduled if the late complications will be suspected. TEE will be performed at three and six months to check for device leak, displacement and thrombosis.
This study was sponsored by Federal state budgetary institution "Russian scientific center for traumatology and orthopedics" n.a. acad. G.A. Ilizarov" of the Ministry of Health of Russian Federation. The study will take place at this center. It is expected to enroll 70 patients aged 6-25 years with NMD, all of whom will be subjected to thoracic and lumbar spinal deformity surgery. Patients will be divided into two groups depending on skeletal maturity. The degree of skeletal maturity will be determined on the basis of an X-ray study of spinal and pelvic bones. The type of surgical correction will depend on the group.
The present study is a multicenter, randomized, double-blind, placebo-controlled study of the safety and efficacy of the drug Unifuzol® (L-arginine) in patients with obliterating atherosclerosis of the lower extremities. The study recruits patients 40-79 years old with a confirmed diagnosis of chronic ischemia of the lower limb and a stable symptom of intermittent claudication that occurs when walking a distance of 100-299 meters. L-arginine improves microcirculation due to activation of nitrogen monoxide production and stimulates capillary blood flow, thus can probably improve the quality of life of patients with intermittent claudication. The criterion for treatment efficacy will be an increase in the maximum walking distance measures before and on the next day after the end of treatment course.
Compare efficacy of 56 mg/m2 carfilzomib administered once-weekly in combination with lenalidomide and dexamethasone (KRd 56 mg/m2) to 27 mg/m2 carfilzomib administered twice-weekly in combination with lenalidomide and dexamethasone (KRd 27 mg/m2) in subjects with relapsed or refractory multiple myeloma (RRMM) with 1 to 3 prior lines of therapy.
The purpose of the current phase I study was to establish bioequivalence, safety, and tolerance of single 300 IU subcutaneous dose of follitropin alfa biosimilar (Primapur) in comparison to that of reference follitropin alfa preparation (Gonal-F) in healthy young female volunteers.
The main purpose of this single-center study is to determine the spectrum and levels of cardiospecific circulating microRNAs in patients with different stages of atherosclerosis according to 640-slice multispiral computed tomography (MSCT).
This study evaluated the efficacy, safety and tolerability of atogepant in participants with chronic migraine. This study included a 12-week treatment period.
This study will evaluate the efficacy and safety of oral PRV-6527 in the treatment of moderately to severely active Crohn's disease
This study evaluates estimate impact of introducers length during endovascular coronary procedures on rate of a radial artery occlusion. For half of participants will use short introducers, while for other will use long introducers during transradial coronary intervention.
The primary objective of this study is to evaluate the efficacy of bulevirtide combination with pegylated interferon in participants with chronic hepatitis delta (CHD).
