This research investigates treatment patterns and the evaluation of homologous recombination repair mutations (HRRm) in circulating tumor DNA (ctDNA) among patients with aggressive high-volume metastatic hormone-sensitive prostate cancer (mHSPC) in the Russian Federation. The study focuses on patients with high-aggressive disease characterized by Gleason scores 8-10 and high-volume disease as defined by specific criteria for bone and visceral metastases. Approximately 400 male patients aged 18 years and older with known tumor HRRm status will participate to better understand demographic and clinical characteristics and treatment approaches in routine practice. The study does not introduce new treatments but observes and collects data as patients receive standard care. Two study visits will occur: the first at baseline to gather medical history, demographic data, and treatment information from diagnosis to enrollment, including routine blood samples for ctDNA and HRRm testing. The second visit will happen at disease progression or after about 12 months to collect follow-up data on progression to metastatic castration-resistant prostate cancer (mCRPC) and subsequent treatments. Blood samples will be analyzed centrally. Participants will have their medical records reviewed and may be interviewed to complete missing information. Data will be entered into electronic records by the study physician. Outcome measures include the proportion of patients receiving various treatments (such as androgen deprivation therapy, chemotherapy, radiation, surgery, and specific inhibitors), duration of therapies, time to progression, mutation presence in ctDNA, testosterone levels, and sites of disease progression over 36 months. Follow-up may be completed by phone if in-person visits are not possible, with the total study duration lasting about 38 months or until data from 400 patients are collected.

Researchers are conducting a national, multicenter, prospective study in the Russian Federation to collect real-world data on patients with aggressive, advanced endometrial cancer (stages III-IV). The study aims to understand the prevalence of molecular markers such as POLE mutations, dMMR/pMMR, p53 abnormalities, HER2, and PD-L1, as well as to observe first-line postoperative treatment approaches in these patients. Approximately 500 female patients with newly diagnosed aggressive subtypes of advanced endometrial cancer will be enrolled across about 30 sites. The study involves two visits aligned with routine clinical practice. At the first visit, demographic and clinical information will be collected from medical records or patient interviews, along with biopsy or archival tumor samples for molecular testing using immunohistochemistry and genetic sequencing methods. The second visit occurs six months after baseline or at disease progression, whichever is earlier, to gather follow-up data on treatments and disease status. No additional procedures beyond standard care are applied. Participants' data will be securely entered into electronic case report forms by study physicians. Researchers will monitor the rates of molecular markers such as POLE mutation positivity, mismatch repair status, p53 abnormalities, PD-L1 expression, and HER2 expression over 24 months. The overall study duration, from first patient enrollment to final data analysis, is expected to be about 27 months or until all data from 500 patients are collected, including follow-up information.

Researchers are conducting an observational multicenter cross-sectional study to better understand the characteristics of adults with uncontrolled severe asthma in Russia who are not receiving biological therapy. The study aims to collect detailed information on the epidemiology, clinical features, treatment patterns, and demographics of these patients across different regions of the Russian Federation, which vary widely in population composition and environmental factors. The study will help fill the gap in data about severe asthma in Russia, especially in patients treated according to standard care but excluding biologics. The study plans to include 5,000 adult patients from about 50 outpatient centers across 50 regions of Russia. It will collect routine clinical data without altering standard medical care or introducing any new diagnostic or therapeutic procedures. The study design includes one visit per patient to gather demographic, clinical, and treatment information, focusing on patients with uncontrolled severe asthma receiving standard treatments like inhaled corticosteroids with other medications but not biological agents. Participants will provide data through medical records and assessments such as the Asthma Control Questionnaire. Researchers will analyze patterns of drug use, clinical characteristics including comorbidities, blood counts, immunoglobulin levels, and lifestyle factors. The study will characterize patients' demographics, treatment trends, and asthma control status from June 2024 to June 2027. Safety monitoring is observational, with no intervention beyond routine care, and the total participation involves a single study visit.

Researchers are conducting a large, non-interventional observational study to better understand adults with uncontrolled asthma across Russia. This study aims to gather detailed information on the demographic and clinical characteristics of these patients, the treatments they receive, and how their condition is managed in routine clinical practice. The study focuses on patients not treated with biologics and covers a diverse population from about 50 regions in Russia, reflecting differences in ethnicity, climate, and economic status. The study will include 9,000 adult patients with uncontrolled mild to moderate asthma who are receiving standard care. Data will be collected during 2-3 visits that follow routine clinical practice schedules. At the first visit, information from the previous 52 weeks will be gathered from medical records and patient interviews. The second visit will take place about 12 weeks later to collect follow-up data on treatment changes and clinical outcomes. For a subgroup of 500 patients using a fixed-dose combination of budesonide/salbutamol at the second visit, an additional third visit will occur 12 weeks later to further monitor treatment and outcomes. Participants will be monitored through medical record reviews and interviews during these visits. Researchers will assess baseline characteristics such as blood eosinophil counts, sputum eosinophils, and total IgE levels, along with treatment profiles and clinical outcomes. The study does not involve any experimental interventions beyond standard care and aims to provide comprehensive real-world data on uncontrolled asthma management in Russia. The total study duration for participants includes up to 24 weeks of follow-up for some patients.

Researchers are monitoring the side effects of COVID-19 vaccines globally, focusing on healthcare workers, adults over 65, and schoolteachers. The study aims to estimate how common local and systemic side effects are for different COVID-19 vaccines, understand risk factors related to side effect frequency and severity, and evaluate long-term effects. It also compares the safety of various vaccines and examines how palliative drugs affect short-term side effect relief. Participants receive one or two doses of different COVID-19 vaccines, including Pfizer-BioNTech, Moderna, AstraZeneca, Sinovac, Sinopharm, Sputnik V, Janssen, CureVac, Novavax, and Covaxin. The study has two phases: a cross-sectional survey on short-term side effects occurring within 30 days after vaccination, and a prospective cohort study assessing long-term vaccine safety and effectiveness, including after booster doses, over five years starting in 2022. Participants complete validated online questionnaires reporting side effects, their timing, duration, and intensity. Researchers collect data on local and systemic side effects up to 30 days post-vaccination and monitor long-term outcomes through yearly follow-ups. The study helps evaluate vaccine safety and supports efforts to reduce vaccine hesitancy by providing independent data on side effects and their resolution.

Researchers are conducting a multi-center, non-interventional study to observe routine diagnostic and treatment practices for patients with unresectable or inoperable locally advanced non-small cell lung cancer (NSCLC) and limited-stage small cell lung cancer (LS-SCLC) in 50 major oncology centers across Russia. The study will collect data from 2000 patients receiving chemo-radiation therapy (CRT) over two years. The aim is to understand demographic and clinical characteristics, diagnostic procedures, treatment approaches, and short-term outcomes of CRT in these patients, without collecting information on treatments following CRT such as durvalumab. The study involves collecting data at two main points: at the start of CRT (either concurrent or sequential chemo-radiation) and after the last dose of radiation therapy, including results from computed tomography (CT) scans. Data collection will be done from patients' medical records in routine clinical practice, and the second data collection is expected to occur within six months after the first visit. The study follows local regulations for adverse event reporting and does not involve additional interventions or treatments. Participants will be adults aged 18 years or older who have locally advanced NSCLC or LS-SCLC and are currently undergoing radiation therapy as part of CRT. Researchers will gather information on patient demographics, disease stage, histology, and clinical status at baseline. The study will monitor treatment details and short-term outcomes after CRT. All data is collected from existing medical records, ensuring no extra procedures for participants. The total participation duration aligns with routine treatment schedules and follow-up visits.

Researchers are evaluating the effectiveness of adjuvant ribociclib combined with hormone therapy (aromatase inhibitors with or without GnRH agonists) in patients with hormone receptor-positive, HER2-negative stage II-III breast cancer in Russia. The study includes both a prospective cohort receiving ribociclib plus hormone therapy and a retrospective cohort treated with hormone therapy alone. The goal is to assess treatment outcomes in different patient subgroups defined by tumor grade, lymph node involvement, and hormone therapy response. Participants in the prospective group receive ribociclib alongside aromatase inhibitors, with or without GnRH agonists, as part of their adjuvant therapy. The retrospective group includes patients treated with aromatase inhibitors alone during a specific period from July 2019 to July 2020. The study collects new data from the prospective group while also analyzing existing patient records from the retrospective group. Throughout the study, researchers monitor invasive breast cancer-free survival at 36, 48, and 60 months following treatment according to standardized criteria. Patient information is gathered from clinical records, including hormone therapy start dates and treatment responses. Safety and effectiveness are assessed by tracking outcomes over several years to better understand ribociclib's role in routine clinical practice for this type of breast cancer.

Researchers are evaluating the rate of chronic kidney disease (CKD) diagnosis in adults with arterial hypertension (AH) who have laboratory markers indicating possible CKD but no prior recorded CKD diagnosis. The study focuses on patients without diabetes mellitus or symptomatic chronic heart failure and aims to better understand CKD prevalence in this specific population in Russia. This multi-center, non-interventional, observational study includes both prospective and retrospective data analysis involving about 10,000 adult outpatients from approximately 50 outpatient sites across 20 regions of Russia. The study will not involve any new diagnostic or treatment procedures beyond routine clinical practice. Retrospective data will be collected from medical records to identify CKD markers measured within 12 months before study inclusion. Patients with adequate retrospective data may have CKD diagnosis confirmed based on two evaluations at least 3 months apart. Those without sufficient retrospective data will undergo laboratory testing during the prospective study period, which will last up to 18 months or until data from 10,000 patients are collected. Participants will be monitored and treated by cardiologists or internal medicine specialists during routine visits. Researchers will collect demographic and clinical information, including medical history and CKD markers, from both retrospective and prospective records. The main outcome is the rate of new CKD diagnoses over the 18-month follow-up. No additional interventions or procedures beyond usual care will be performed, and the study aims to support earlier CKD detection and improved clinical outcomes in patients with hypertension.

Researchers are conducting an observational surveillance study to identify the genetic types of rickettsia bacteria causing rickettsioses in patients from various regions of Russia. The study focuses on patients with diagnosed or suspected tick-borne rickettsioses. It aims to link genetic information of the bacteria with patients' medical histories, disease progression, symptoms, and treatments to find clinical patterns specific to different causative agents. The study is non-interventional and has received ethical committee approval. No changes are made to patients' routine treatment or diagnostic procedures during the study. Biological samples such as blood, plasma, buffy coat, serum, or eschar swabs collected during standard diagnostics are used for genetic analysis of the rickettsia species. These residual diagnostic samples are collected only after patients or their legal representatives give written informed consent. Physicians complete individual case report forms to record relevant medical information for each participant. Participants provide informed consent, and their medical history, symptoms, disease course, and treatments are recorded. The genetic typing of rickettsia bacteria is performed within up to 4 weeks after sample collection. The study monitors these genetic findings alongside clinical data to improve understanding of rickettsioses. There is no intervention or alteration in patient care, and the study respects current medical standards throughout its observation period.

Researchers are conducting a multicenter observational study in the Russian Federation to examine treatment approaches, patient characteristics, and biomarker prevalence in men with newly diagnosed high-aggressive metastatic hormone-sensitive prostate cancer (mHSPC). The study focuses on patients with Gleason scores between 8 and 10 who were diagnosed within two years before enrollment. It aims to collect information on demographic and clinical features, treatment methods, and biomarker status, including PTEN loss, HER2-positive status, HRR mutations, and HRD positivity. Participants will not receive any additional procedures beyond their routine clinical care. Data will be collected during a single visit and include medical history, treatment received, and outcomes. Tumor tissue samples taken during standard care will be tested centrally for biomarkers using immunohistochemistry and next-generation sequencing. Approximately 400 patients across around 30 sites will be enrolled over about 27 months or until the target number is reached. During the study visit, researchers will gather information from medical records and patient interviews, entering data into an electronic case report form. No follow-up visits are planned. Key outcomes measured include the types and proportions of treatments patients have received over 24 months, such as hormone therapy, chemotherapy, radiation, surgery, and combination therapies, as well as biomarker test results. The study duration includes enrollment and data collection until database lock.
