Hereditary Transthyretin Amyloidosis Polyneuropathy in Patients With Carpal Tunnel Syndrome in Russia

ATTR PN is a genotypically, phenotypically and geographically variable disease with a poor prognosis, albeit available disease-modifying drugs can change the disease trajectory. Thus country-specific epidemiologic data collection and identification of early stage PN, including previously misdiagnosed patients, is crucial to improve outcomes and quality of life. However, no observational studies on the epidemiology of ATTR PN in the whole Russian population, or in patients with CTS, have been performed. Therefore, there is a need to conduct a large-scale observational study to determine the prevalence of ATTR PN in Russia, obtain information on patients' clinical characteristics, and determine their medical needs. The approaches to diagnosis of ATTR PN in Russia over the past few years have been characterized by the use of heterogenous methods, partially explained by the lack of availability of molecular genetic testing, which is essential to diagnose the presence of pathogenic mutation in patients with hereditary ATTR PN. Thus, recent introduction of such tests into routine clinical practice may allow to assess reliable epidemiologic data including estimation of true ATTR PN prevalence among patients with CTS, which can often be the first manifestation of the disease. Earlier recognition, in turn, may lead to timely treatment initiation and change in the prognostic outlook of ATTR PN patients. In order to assess the prevalence of ATTR PN in patients undergoing surgery for CTS in Russia this study will retrospectively include patients with the diagnosis of CTS undergoing surgery between the 1st January 2021 and the 1st September 2024. Suspicion of ATTR PN will be assessed in each case, and diagnostic tests (comprehensive neurological examination including nerve conduction study (NCS) combined with molecular genetic testing) to confirm or exclude the disease will be conducted prospectively in eligible patients. In addition to that, clinical features, concomitant manifestations, and diagnosed genotypes will be analyzed to examine characteristic ATTR PN patient profiles in the Russian Federation.

Clinical and demOgRaphic Features of Patients With Uncontrolled Severe Asthma in Russia (CORSAR)

There are limited epidemiological data of the patients with uncontrolled severe asthma in Russia since there is no unified system for regular monitoring of patients with severe asthma in the country. The systematic information about complications and comorbidities, about the treatment approaches and their effectiveness in the Russian population is also absent. The observational registry is really important to describe the epidemiological characteristics of the disease and to analyse the clinical characteristics of the various subgroups of patients. This is an excellent starting point to be able to investigate the characteristics of the disease in detail. The Russian Federation consists of 85 regions with a total population of more than 145 million people. The regions differ in ethnic composition, age, gender, climate, ecology, economic level, prevalence of asthma in general and severe asthma in particular. Previously reported observational registries are International Severe Asthma Registry (ISAR) and Russian Severe Asthma Registry (RSAR), both studies included patients regardless of whether patients received biological agents or not. The percentage of patients receiving biologics in these studies was 25.4% and 10.6% respectively. Thus, there is a need to perform a large-scale observational registry in regions of the country with a sufficient size of population to obtain information on SA epidemiology, clinical and demographic characteristics, to describe main clinical outcomes and evaluate existing associations between observed treatment patterns and clinical outcomes in real clinical practice in patients with uncontrolled SA not receiving biologic therapy. Trial will have cross-sectional design and will include 1 visit for obtaining the patient's demographic and clinical data. To allow wide data coverage the study will involve at least 50 regions of Russian Federation; in each region 100 patients will be recruited. The total size of study population will be 5 000 patients.

Thus, there is a need to perform a large-scale observational registry in regions of the country with a sufficient size of population to obtain information on uncontrolled asthma epidemiology, clinical and demographic characteristics, to describe main clinical outcomes and evaluate existing associations between observed treatment patterns and clinical outcomes in real clinical practice in patients with uncontrolled asthma not receiving biologic therapy. Trial will have ambispective design and will include 2 visits for obtaining the patient's demographic and clinical data. To allow wide data coverage the study will involve at least 50 regions of Russian Federation; in each region 200 patients will be recruited. The total size of study population will be 10 000 patients. All data will be collected during 2 visits carried out according to routine clinical practice for observation and treatment of patients with uncontrolled asthma. At visit 1, baseline data of 52 weeks prior to inclusion will be collected by physician based on the patient's medical records and interview during the visit. Visit 2 (final visit) will be conducted after 3 months in order to collect follow-up data which coincides with the recommended dates. Information on changes in the treatment of uncontrolled asthma and on clinical outcomes will be collected. This non-interventional study does not imply any intervention into a routine clinical practice, and does not provide for any diagnostic and therapeutic procedures other than those used in routine practice.

Masitinib in Patients With Symptomatic Mild to Moderate COVID-19

The primary objective is to evaluate the virologic efficacy of masitinib plus Best Supportive Care (BSC), with respect to placebo plus BSC in reducing viral shedding of SARS-CoV-2 in patients with symptomatic mild to moderate COVID-19. Patients will be randomized into one of the following treatment groups (all patients will receive BSC): 1. Masitinib 3.0 mg/kg/day for 10 days versus corresponding placebo 2. Masitinib 3.0 mg/kg/day for 2 days then 4.5 mg/kg/day for 8 days versus corresponding placebo 3. Masitinib 3.0 mg/kg/day for 2 days then 4.5 mg/kg/day for 2 days then 6.0 mg/kg/day for 6 days versus corresponding placebo Treatments will be administered for 10 days and patients will be followed for 1 month. The treatment groups will be compared to pooled placebo after unblinding. Regarding Best Supportive Care, for patients with a score of 2 and 3 (ambulatory) on the 10-score WHO clinical progression scale, Best Supportive Care is best available therapy in the country at the choice of the investigator excluding any antiviral treatment whether indirect (Ribavirin, Hydroxychloroquine or Chloroquine) or direct (anti-polymerase or antiprotease, including lopinavir/ritonavir fixed dose combination), other investigational treatments for SARS-CoV-2, plasma from a person who recovered from COVID-19, monoclonal antibody therapies and vaccine. For patients with a score of 4 and 5 (hospitalized) on the 10-score WHO clinical progression scale, Best Supportive Care is dexamethasone.

pRospective Evaluation of Clinical Outcomes in Patients With metAsTatIс melanOma Treated With dabrafeNib and trAmetinib in reaL practicE

Rationale and background It is now accepted by the majority of experts in oncology that most effective and safe therapy options should be considered for first-line treatment, including adjuvant setting. As the routine administration of drugs including dosing, treatment interruptions, and early termination in clinical practice may vary from procedures used in clinical trials, post-authorization "real-world" data are important to quantify feasibility, acceptance, and practical considerations on prescription of targeted therapy with Dabrafenib+Trametinib. Therefore, it is of great interest for clinical and scientific communities to evaluate patient and treatment choice used in routine practice of Russian oncology centers. The aim of this study is to asses clinical outcomes of patient receiving Dab+Tram in different substages of resectable melanoma and different lines in metastatic melanoma., Additionally, it is of interest to gain insights into real world data regarding quality of life of melanoma patients treated with Dabrafenib and Trametinib in adjuvant or metastatic setting. Research question and objectives Primary objective The primary objective in the study is to estimate relapse-free survival (RFS) in melanoma patients in adjuvant settings and progression free survival (PFS) in melanoma patients in metastatic settings. Primary endpoints • The primary efficacy endpoint of the study is 12-month RFS rate, definded as the time form index date to the date of first documented relapse or death due to any cause. The primary efficacy endpoint of the study is 12-month PFS rate, defined as the time from the index date to the date of the first documented progression by investigator judgement or death due to any cause. If a patient has not had an event, PFS will be censored at the date of the last tumor assessment Secondary objectives - To describe patient populations receiving dabrafenib and trametinib for stage III resectable melanoma with respect to demographics and clinical characteristics at index date (baseline). - To describe patient populations receiving dabrafenib and trametinib for stage IV metastatic melanoma with respect to demographics and clinical characteristics at index date (baseline). - Evaluate retrospectively the sequence of therapy prior to initiating treatment with Dabrafenib and Trametinib. - Analyze prospectively treatment options following disease recurrence or progression on treatment with Dabrafenib and Trametinib. - Analyze proportion (%) of patients receiving adjuvant therapy with Dabrafenib and Trametinib for melanoma stage IIIA/IIIB/IIIC/IIID - Analyze proportion (%) of patients receiving Dabrafenib and Trametinib in 1L/2L/3L/later lines in metastatic settings. - Assess clinical outcomes (including treatment duration, treatment discontinuation rate) in melanoma patients treated with Dabrafenib and Trametinib in adjuvant settings in real-world practice. - Assess clinical outcomes in melanoma patients treated with Dabrafenib and Trametinib in metastatic settings (including median PFS, treatment duration, RR and) in real-world practice. - Assess safety of therapy of interest: rate of adverse events associated with the therapy, proportions of patients and reasons of dose adjustment on dabrafenib and trametinib, discontinuation rate and reasons of discontinuation in melanoma patients treated with Dabrafenib and Trametinib in adjuvant and metastatic in real-world practice. - Describe changes in patient-reported symptoms and quality of life (QoL) in melanoma patients treated with Dabrafenib and Trametinib in real-world setting. Study design Patients will attend study sites in accordance with routine clinical practice. It is assumed that visits will performed every 3-4 months, as it is stated by the current guidelines (1). Patients will undergo standard procedures and tests according to clinical guidelines and physician's judgement (1). Available data from routine clinical management of the patients will be collected in the course of visits to investigation site. The supposed duration of observation within the study is 1 year which corresponds to the requested duration of adjuvant therapy and is in line with the median PFS - 11.1 months according to the COMBI D/V trials' analysis for dabrafenib+trametinib therapy in the first line treatment of metastatic cutaneous melanoma with BRAF mutation (2). The enrollment period will continue for two years. Baseline assessments will include collection of patient demographic data, disease history, treatment history, laboratory data and physical examination results as assessed by clinicians and patient reported outcomes (PROs) for symptoms and QoL. Treatment history will include all pharmacological therapy, its duration, response duration, reason for discontinuation. QoL assessment is not a part of routine practice for some investigation sites, hence, QoL will be evaluated if it does not interfere routine practice. At each following visit (as indicated above, approximately each 3-4 months up to 1 year) available information on treatment status, response and progression, PROs, patient performance status and any relevant adverse occurrences will be collected. Setting and study population This study is planned as a prospective non-interventional multicenter study. This study is observational in nature and does not impose a therapy protocol, diagnostic/therapeutic interventions or a visit schedule. Patients with resectable or metastatic BRAF+ melanoma, in that treatment with dabrafenib and trametinib was initiated, either newly diagnosed or progressive during prior lines of therapy, will be included into the study. Initiation of dabrafenib+trametinib therapy will be considered an index event. Adult patients receiving dabrafenib and trametitnib for adjuvant or metastatic melanoma treatment will be enrolled into study. Variables All data will be collected in the course of prospective visits of patient to the clinical site according to routine practice. Demographic, disease and treatment-related variables will be collected in order to ensure completeness of data for endpoint analysis. Definitions of variables for analysis will be given in the relevant section of protocol. Data sources Medical records and other disease-related documents will be used in the study. Study size This study does not test any pre-defined statistical hypotheses therefore sample size and power calculation projections are not applicable. Since there is no formal hypothesis-testing, sample size for this study is based on the feasibility of enrolling the desired population during the enrolment period for this study. Data analysis This is an exploratory study and no comparative analysis is planned. Descriptive statistics will be tabulated for the demographic and clinical characteristics and outcome variables. In all cases, point estimates as well as the corresponding two-sided 95% CI will be presented. No missing value imputation will be performed. Kaplan-Meier method will be used for the analysis of time-to-event.
