There are about 6441 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.
This is a prospective, single-center, non-randomized phase II study. Patients with germ cell tumors of gonadal and extragonadal localization who have progressed after prior platinum-containing first-line chemotherapy will receive high-dose chemotherapy with TI (2 cycles) folollowed by high dose CE chemotherapy with autologous stem cell transplantation (3 cycles). The primary endpoint of the study is to evaluate the efficacy high-dose chemotherapy as second-line drug therapy for patients with advanced germ cell tumors.
The primary objective is to evaluate the efficacy and toxicity of high versus low intensity therapy options in patients with refractory forms and early relapses of acute myeloid leukemia (R/R AML) who are scheduled for allogeneic hematopoietic stem cell transplantation (alloHSCT).
Hypospadias is among the most common congenital genital malformations in boys and is typically treated through surgical intervention. During pediatric urological surgery, caudal anesthesia, also known as a caudal block, is frequently employed as a regional anesthetic technique. It has proven to be a safe and effective anesthetic approach in children, with a low rate of anesthesia-related complications. However, despite the low incidence of complications directly associated with the caudal block, there is limited and inconclusive evidence regarding its impact on surgical complications. Therefore, this randomized controlled superiority trial aims to evaluate whether the use of caudal anesthesia, compared to the dorsal penile block, is associated with an increased incidence of urethrocutaneous fistulas and glans dehiscence following hypospadias repair.
This is a multicenter observational study consisting of retrospective and prospective phases. The retrospective phase will entail secondary data collection from electronic or paper medical records of patients who underwent surgery for CTS to assess their probability of having ATTR PN.
Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide. Microsatellite instability or mismatch repair deficiency occurs in 20% of CRC, and is predominantly found in non-metastatic tumors. The success of the CheckMate 142 and KEYNOTE-177 clinical trials has shifted the treatment paradigm of the MSI/dMMR CRC, which has led to the adoption of immune checkpoint inhibitors (ICI) by international treatment standards. However, despite the encouraging effects of ICI, up to 30% of patients are resistant to treatment and exhibit rapid disease progression shortly after starting ICI. On the other hand, around 30% of patients treated with ICI demonstrate prolonged responses to the treatment with a duration of response of over 40 months. Furthermore, for ~10% of patients, treatment with ICI results in pseudo-progression - a phenomenon of a short-term increase followed by the decrease of the tumor volume. Currently, the mechanisms and biomarkers associated with the response or resistance to ICI in MSI-positive CRC are largely unknown. Select studies suggest that BRAF mutations (specifically, BRAF p.V600E) might negatively affect the patients' progression-free survival following ICI, however, these data are premature. The primary hypothesis is that the clonal heterogeneity and the evolution of MSI status of MSI-positive CRC will play a role in the development of ICI treatment resistance. The primary objective of the study is to investigate the dynamics of MSI status in serial liquid biopsy samples from patients with MSI-positive tumors receiving ICI.
The study is devoted to the impact of preemptive regional Transversus abdominal plane block on the postoperative acute and chronic pain after elective Transabdominal preperitoneal (TAPP) inguinal hernia repair.
Prospective, post-registration, interventional, randomized, in parallel groups, multicenter Eurasian clinical study of DERIVO®/DERIVO® mini Aneurysm Embolization Device, Europe-Asia
In the modern population, mortality and disability from cardiovascular diseases is predominant and is realized as a major medical and social problem. The study of mechanisms of development of age-related diseases, such as coronary heart disease (CHD), has demonstrated multiple qualitative and quantitative changes of metabolites in biological fluids of the body - blood, in the vascular wall, as well as in the tissues of vital organs. In routine clinical practice only about a dozen metabolic parameters are determined by standard laboratory methods. The proposed approach belongs to a new scientific direction , wich development is aimed at individualization of approaches to risk stratification of cardiovascular diseases and their complications. The data obtained in this project will allow to create a base of medical knowledge about spectral characteristics of blood serum, which most fully reflect the metabolic profile associated with atherosclerosis of coronary arteries. Researchers offer so-called multiplex diagnostics when multiple parameters of a biological object obtained by serum biochemical analysis and optical scattering analysis are used. Recognition of this big data is possible only by methods of mathematical analysis, which can take into account the degree of deviations, their directionality in each point of the spectral characteristic. Until recently, the standard setup for Raman light scattering studies had significant dimensions. The high cost of such installations made it difficult to widely use the method of optical spectroscopy for rapid analysis of medical objects. In recent years, the situation on the market of scientific instrumentation has changed radically, which allowed to significantly reduce and cheapen all components of Raman installations.This simplification and cheapening allows to bring optical research in medicine (optical biopsy) to a new level of use, directly into clinical laboratories. Novelty: This area of research belongs to high-tech and is very little represented in Europe. The prospect of using Surface Enhanced Raman spectroscopy (SERS) to determine subclinical lesions of coronary arteries and for risk stratification of diseases associated with atherosclerosis is quite unique and wasn't explored yet.
