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.
This study involves two non-randomized groups of patients: the observation group and the comparison group. The comparison group will retrospectively include data on 29 patients with oligometastatic HER2-positive breast cancer who received treatment with trastuzumab-emtansine and had a history of SRT. The prospective part of this study aims to include 29 patients with oligometastatic HER2-positive breast cancer. These patients will undergo SRT followed by the administration of trastuzumab emtansine 24 hours after the SRT. The combined effect of stereotactic radiation therapy on a metastatic lesion followed by anti-HER2 therapy in the 2nd line - trastuzumab emtansine, remains unexplored. This study plans to evaluate the effectiveness of combining systemic therapy and local control methods (SRT) in patients with oligometastatic HER2-positive breast cancer. It will be the first time the efficacy and toxic profile of this new combined treatment method in this patient population will be studied. This basket trial evaluates trastuzumab emtansine for oligo-metastatic breast cancer with the aim of inducing deep responses, long-lasting disease remissions, and potentially cure.
Surgery plays significant role in treatment of neurogenic tumors, both for benign ganglioneuroma and for high risk neuroblastoma. The world literature has accumulated large experience in laparoscopic surgery for abdominal neuroblastoma. The presence of IDRF (image-defined risk factors) and tumor size (>4-7 cm) are considered as common contraindications for minimally invasive surgery in neuroblastoma. However, the recent studies have shown that presence of IDRF is not an absolute contraindication for laparoscopic surgery. This open-label, nonrandomized, observational, phase III evaluates role and weight of different surgical risk factors (including IDRF, tumor size, tumor localization, tumor volume/patient height ratio, previous open surgical procedures, previous chemotherapy etc.) in the laparoscopic neuroblastoma resections. The aim of this study is to create novel risk factors scoring system for laparoscopic surgery in abdominal neuroblastoma.
The aim of this study is to confirm the comparability of the efficacy and safety profiles of BCD-264 and Darzalex as monotherapy for relapsed and refractory multiple myeloma in subjects previously treated with proteasome inhibitors and immunomodulatory drugs, and who had disease progression on prior therapy.
The purpose of this study is to assess the efficacy and safety of DMB-I for the treatment of patients with Alzheimer type dementia.
This is a multicenter prospective randomized blind controlled trial with a sham procedure group of the efficacy and safety of cardioneuroablation as a method of treating symptomatic bradycardia without a permanent pacemaker implantation
Randomized, double-blind, placebo-controlled study will determine the clinical efficacy and safety of Lymphoblock in the prevention of postoperative retroperitoneal chylo-/lymphorrhoea in patients with open surgical treatment of the thoracoabdominal aorta. It is planned to recruit 138 clinical observations. Efficacy will be evaluated based on clinical and laboratory data.
The study will collect the information on clinical effects and safety of the basic therapy of acute respiratory viral infection (ARVI) + Cycloferone® and basic therapy of ARVI1 + Arbidol® in real-life clinical settings.
Clinical Trial of the Efficacy and Safety of Raphamin in Prevention of Recurrences of Chronic Bacterial Cystitis
There are few studies in the literature that have evaluated the effects of using percutaneous stimulation of the auricular branch of the vagus nerve for sports purposes (to accelerate recovery after physical exertion). It has been demonstrated that tVNS in athletes improved the rate of heart rate recovery, reduced lactic acid levels in blood plasma, reduced pain, reduced overtraining syndrome and fatigue levels.
There are many predictors that may influence the development of corneal graft rejection after penetrating keratoplasty. In our study investigators analysed the results of keratoplasty and the risk factors for graft rejection. Investigators analysed data from 493 patients who underwent penetrating keratoplasty between 2011 and 2019. Keratoplasty outcomes were followed up at subsequent clinic visits until December 2021. Then, 93 medical records were selected (taking into account the completeness of the medical records) and divided into two groups based on the primary diagnosis that was an indication for keratoplasty: high-risk and low-risk patients. Investigators then estimated the survival time (clear graft) of the corneal graft using Kaplan-Meier statistical survival analysis. Investigators also investigated the factors that influence corneal graft opacity.
