简要总结
The purpose of this study is:
- to evaluate safety of the liquid dosage form of Ergoferon in the treatment of acute upper respiratory tract infections in adults;
- to evaluate clinical efficacy of the liquid dosage form of Ergoferon in the treatment of acute upper respiratory tract infections in adults.
详细描述
Design: multicenter double-blind placebo-controlled parallel-group randomized clinical trial.
The study will enrol outpatient subjects of either gender aged 18-60 years with clinical manifestations of upper respiratory tract infections (URTI) during seasonal morbidity who are presented to the doctor within the first day of the disease onset. Signed information sheet for the patient is obtained from all participants prior to the screening procedures. Medical history, concomitant medication, tympanic thermometry, patient examination by a doctor, assessment of URTI symptoms severity are performed at screening visit.
URTI symptoms severity examination by the physician is based on Common Cold Questionnaire (CCQ) (PLoS One. 2008; 3(3): e1802. Published online 2008 Mar 19. doi: 10.1371/journal.pone.0001802).
If a patient meets the inclusion criteria and does not have any exclusion criteria, at Visit 1 (Day 1), he/she is randomized into one of two groups: the 1st group (Ergoferon group) patients receive Ergoferon according to the scheme for 5 days; the 2nd group (Placebo group) patients receive placebo according to Ergoferon dosage regimen for 5 days.
The patients are provided with a patient diary where they record tympanic temperature (using tympanic thermometer provided by sponsor) twice a day and URTI symptoms severity according to the Wisconsin Upper Respiratory Symptom Survey - 21 - Daily Symptom Report (WURSS-21©, Wisconsin Upper Respiratory Symptom Survey, 2004.

- •Oncological diseases.
- •Medical history of polyvalent allergy.
- •Allergy/intolerance to any of the components of medications used in the treatment.
- •Impaired glucose tolerance, diabetes mellitus type 1 and

研究组 & 干预措施
Placebo (5 ml 3 times a day)
Oral use. Placebo using Ergoferon scheme.
干预措施: Placebo (Drug)
Ergoferon (5 ml 3 times a day)
Oral use. Dose per administration: 1 dosing spoon (5ml) without food. For best effect, the solution should be held in the mouth before swallowing.
Dosing scheme. One dose every 30 minutes for the first 2 hours, followed by three more doses spaced regularly during the rest of the day. From day 2 to 5: 1 spoon taken 3 times daily.
干预措施: Ergoferon (Drug)
结局指标
主要结局
Average Duration of Fever.
时间窗: 1-7 days
Primary outcome measure is based on the indicators of tympanic thermometry recorded by the patient in the diary during the period of treatment and observation. Thermometry is performed twice a day (morning and evening). The criterion of Duration of Fever is the time from enrollment to the first return to the afebrile state or the normalization of tympanic temperature (tympanic temperature ≤37.0 degree Celsius \[°C\]).
次要结局

- Dynamics of Acute Upper Respiratory Tract Infections (URTI) Symptoms Severity According to the Physical Examination by the Doctor.(Day 1, 3, and 7.)
- Percentage of Patients Who Have a Worsening of Disease.(Days 1, 2, 3, 4.,5, 6, and 7.)
- Dynamics of Acute URTI Symptoms Severity According to the Daily Wisconsin Upper Respiratory Symptom Survey - 21 (WURSS-21) Assessment of the Patient (Including the Total WURSS-21 Score, "Symptoms" Domain Score, and "Ability" Domain Score).(Days 1 to 8.)
