Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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".

Raphamin

Per os without food. The tablet should be kept in mouth until completely dissolved.

On day 1 of treatment, 8 tablets should be taken using the following regimen: 1 tablet every 30 minutes for the first 2 hours (5 tablets in total for 2 hours), then 1 more tablet 3 times at equal intervals during the same day. On day 2 and onwards, 1 tablet should be taken 3 times a day. The duration of treatment is 5 days.
