Conditions: Acute Upper Respiratory Tract Infections
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 342
Healthy volunteers: no

Brief summary:
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.

Detailed description:
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.

Created by Bruce Barrett MD PhD et al., UW Department of Family Medicine, 777 S. Mills St. Madison, WI 53715, USA).

In addition, antipyretic administration (if applicable), as well as any possible worsening of the patient's condition (if applicable, for Adverse Events (AEs) evaluation), are also be recorded in a patient diary. An investigator provides the instructions on filling out the diary and helps the patient to make first records of URTI symptoms severity and tympanic temperature in the diary.

Patients are observed up for 7 days (screening and randomization for 1 day, study therapy 1-5 days, the follow-up period for 2 days). During treatment and follow-up period two visits are scheduled (at home or at the study site) on days 3 (Visit 2) and day 7 (Visit 3). At Visits 2 and 3, the investigator will carry out a physical examination, record dynamics of URTI symptoms severity (according to CCQ) and concomitant therapy, and check patient diaries. Treatment compliance is evaluated at Visit 3.

During the study, symptomatic therapy and therapy for underlying chronic conditions are allowed with the exception of the drugs indicated in the section "Prohibited Concomitant Treatment".
