The Efficacy and Safety of Raphamin in the Treatment of Acute Rhinosinusitis in Adult Patients

A multicenter, double-blind, placebo-controlled, randomized, parallel-group clinical trial. The trial will enroll outpatients of either gender aged 18 to 75 years with clinical manifestations of acute rhinosinusitis (ARS) within the first 48 hours after the disease onset. Patient recruitment will be conducted during the seasonal incidence of acute respiratory viral infection (ARVI). After the patient signs the information sheet and informed consent form for participation in the clinical trial, the medical history will be collected, thermometry, objective examination, laboratory tests will be performed, concomitant diseases and concomitant therapy will be recorded. The severity of ARS symptoms will be assessed using Major Symptom Score (MSS). Initially (Day 1) and on Visits 2 (Day 4) and 3 (Day 7), the patient together with the investigator, fills in the MSS scale and completes the Sino-Nasal Outcome Test questionnaire for assessing the quality of life of patients with diseases of the nose and paranasal sinuses (SNOT-22). If all inclusion criteria are met and there no any exclusion criteria, at Visit 1 (Day 1), the patient is randomized into one of two groups: Group 1 patients will receive Raphamin according to the dosage regimen for 5 days; Group 2 patients will receive Placebo using the Raphamin dosage regimen for 5 days. The trial uses an electronic patient diary (EPD) where the patient daily morning and evening will make records axillary body temperature (measured with a classic mercury-free thermometer) and symptoms of the disease (according to the MSS). In addition, administration of basic therapy drugs (if applicable) as well as any possible worsening of the patient's condition (if applicable, to assess safety / to record adverse events) should also be recorded in the patient diary. The investigator will instruct the patient on how to complete the diary. At Visit 1, the patient will record the severity of ARS symptoms and body temperature in the diary together with the physician. The patient will be observed for 14 days (screening, randomization - up to 1 day, treatment - 5 days, follow-up - up to 14 days). During the treatment and follow-up period, patients/physicians will pay 3 visits, on days 1, 4 and 7 (Visits 1, 2 and 3) - at a medical center or at home; a phone visit (Visit 4) will be on day 14. At Visits 2 and 3, the investigator performs objective examination, records changes in the disease symptoms, concomitant therapy, and controls the filling of the diary, evaluates the patient's compliance (Visit 3). At Visit 4 (a phone visit), the investigator evaluates safety, collects information about the patient's condition, the presence/absence of complications, the use of antibiotics, and the presence/absence of hospitalization of the patient. Symptomatic therapy and therapy for concomitant diseases will be permitted during the trial except for the drugs listed under "Prohibited Concomitant Treatment".

Clinical Trial of the Efficacy and Safety of Raphamin in the Treatment of ARVI in Children Aged 3-12 Years

Design: a multicenter, double-blind, placebo-controlled, randomized, parallel-group clinical trial. The trial will enroll outpatients of either gender aged 3 to 12 years with clinical manifestations of acute respiratory viral infection (ARVI) within the first 24 hours after the disease onset. Patient enrollment will be conducted in 2 stages during the seasonal incidence of ARVI. First, children aged 6-12 years will be enrolled in the trial. Once the required number of patients is reached, an "unblinded" interim analysis with the primary efficacy endpoint assessment and safety analysis will be performed. Based on the data from the unblinded interim analysis, a decision will be made whether the age range of enrollment can be expanded from 3 to 12 years. Patient enrollment will not be stopped until the results of the "unblinded" interim analysis are available. After the parent/adopter signs the information sheet and informed consent form for the patient's parents/adopters to participate in the clinical trial, the medical history will be collected, thermometry, objective examination, laboratory tests will be performed, and concomitant therapy will be recorded. The severity of ARVI symptoms will be assessed using a 4-point scale. The nasopharyngeal swabs for PCR diagnosis and verification of respiratory viruses will be performed prior to therapy to confirm the viral etiology of ARVI. If a patient meets all inclusion criteria and does not have any exclusion criteria, at Visit 1 (Day 1), they will be randomized into one of two groups: Group 1 patients will receive Raphamin according to the dosage regimen for 5 days; Group 2 patients will receive Placebo using the Raphamin dosage regimen for 5 days. The trial will utilize an electronic patient diary (EPD) where the patient will make daily records of morning and evening axillary body temperature (measured with a classic mercury-free thermometer) and symptoms of the disease (ARVI Symptom Severity Score). In addition, antipyretic dosing (if applicable) as well as any possible worsening of the patient's condition (if applicable, to assess safety / to record adverse events) will also be recorded in the patient diary. The investigator will instruct the parent/adopter on how to complete the diary. At Visit 1, the parent/adopter together with the physician will record the severity of ARVI symptoms and body temperature in the diary. The patient will be observed for 14 days (screening, randomization - up to 1 day, treatment - 5 days, follow-up - up to 2 days; deferred "phone visit" - day 14). During the treatment and follow-up period, patients/physicians will pay 3 visits, and the fourth "phone visit" will be scheduled additionally: 1) physician/patient visits - on days 1, 5 and 7 (Visits 1, 2 and 3) - at the health center or at home; 2) a phone "visit" by the physician (Visit 4) - on day 14. During Visits 2 and 3, the physician will perform objective examination, record changes in the disease symptoms, concomitant therapy, and monitor the completion of the diary. During Visit 3, compliance will be assessed and laboratory tests will be performed. A phone "visit" will be performed to interview the parent/adopter about the patient's condition, presence/absence of secondary bacterial/viral complications, and use of antibiotics. Symptomatic therapy and therapy for concomitant diseases will be permitted during the trial except for the drugs listed under "Prohibited Concomitant Treatment".

Observational Study of Efficiency of Cytoflavin, in Patients With Ischemic Stroke Not Receiving Reperfusion Therapy

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 Trial of the Efficacy and Safety of Raphamin in Prevention of Recurrences of Chronic Bacterial Cystitis

Trial design: double blind, placebo-controlled, randomized in parallel groups clinical trial. The trial includes female outpatients aged 18 years or older with typical symptoms of chronic bacterial cystitis. The severity of typical symptoms of recurrence (exacerbation) should be 7 points or more according to the subscale "Typical symptoms" of the scale "Acute Cystitis Symptom Scale" (ACSS). At Visit 1 (Day 1), after signing the patient information sheet and the informed consent form for participation in the clinical trial, complaints and medical history are collected, a physical examination is performed, and the severity of typical symptoms of cystitis is assessed using ACSS, collection of urine biosamples for urine analysis with microscopy and bacteriological examination (for identification the sensitivity of microorganisms to antibiotics), ultrasound examination of the urinary system (kidneys, bladder), and concomitant therapy is recorded. Urinalysis, general and biochemical blood tests are planned in at least 190 patients. If the patient meets inclusion criteria and does not meets exclusion inclusion criteria at Visit 1 (Day 1), the patient is randomized to one of two groups: patients of Group 1 take Phosphomycin (3 g once) and Raphamin according to the therapeutic and preventive regimen for 10 days; patients of Group 2 use Phosphomycin (3 g once) and Placebo according to the Raphamin regimen for 10 days. If there is no effect from treatment within 48 hours or phosphomycin-resistant strains are detected, the physician conducts unscheduled visit and gives the patient an alternative drug Cefixime (400 mg). Cefixime is taken 1 times a day at a dose of 400 mg for 5 days or more (the duration of the course is determined by the physician). All patients are provided with Phosphomycin, if resistance to it is detected - with alternative antibiotic Cefixime. If microorganisms resistant to both Phosphomycin and Cefixime are detected, the patient is excluded from the trial, and the physician prescribes a treatment strategy in accordance with current standards. In Electronic Patient Diary (EPD) the patient records the severity of typical cystitis symptoms using ACSS once a day at approximately the same time. Symptoms are recorded in the EPD from the patient's enrollment until Visit 2 (within 10 days of study drug administration), as well as during 10 days of treatment for each subsequent relapse (exacerbation). In addition, any possible deterioration of the patient's condition (if applicable) is recorded in EDP to assess safety and record adverse events. The study physician instructs patients to complete the diary. The first ACSS marks in the EDP are made by patient together with physician at Visit 1. EDP is available for filling throughout the patient's participation in the study. Once a week, the patients get SMS reminder: "If you have symptoms of the disease, enter them in the diary and contact the study physician. Don't forget to take your medication." In total, patient's follow-up lasts for 24 weeks. In the process of treatment and observation, 4 visits are scheduled: at day 1 (Visit 1) and day 11 (Visit 2), then at weeks 12 and 24 (Visits 3, 4). Visits 1, 2 and 4 are face-to-face (patient visits trial site); physician conducts physical examination, records symptoms and concomitant therapy, and checks the EPD. At Visit 2 (Day 11+3), the physician gives Phosphomycin/Cefixime and a study drug to patient, to treat a possible subsequent recurrence of cystitis. Blood and urine biosamples are taken from the patient who signed the ICF for taking biological samples (for safety assessment). The study drug received by the patient at Visit 1 should be returned to assess the patient's adherence to the study treatment. Phosphomycin/Cefixime also returns. Visit 3 (Week 12 ± 3 days) is conducted by correspondence (telephone), in order to interview the patient about her condition. In case of new recurrence of cystitis, patient contacts with trial physician by phone. On the basis of complaints and symptoms, physician makes conclusion about the onset of chronic cystitis recurrence. Patient completes ACSS in EPD. For a recurrence of cystitis, patient takes Phosphomycin (or Cefixime) and trial product (Raphamin/Placebo for 10 days). At the end of 10 days of treatment, an unscheduled face-to-face visit takes place (Day 11+3 days after the onset of recurrence), at which the patient returns the trial product and Phosphomycin/Cefixime, then the physician dispenses a new pack of trial product and Phosphomycin (or Cefixime) to treat a possible new recurrence of cystitis. Visit 4 (Week 24 ± 3 days) is the final one; complaints are assessed, the patient undergoes a physical examination, returns the trial product and fills in a visual analogue scale (VAS), which assesses the degree of patient satisfaction with the therapy.
