Brief summary

This randomized, single blind clinical study was conducted to investigate the clinical efficacy and safety of the drug Amizon (enisamium iodide), in comparison with placebo for the treatment of patients with acute respiratory viral infections (ARVI), including influenza. Enisamium iodide is an antiviral small molecule. Adult patients were enrolled and randomised into 2 groups. On the first day of the onset of symptoms of ARVI, one group of patients took Amizon tablets (active ingredient enisamium iodide) for 7 days; the other group of patients took matching placebo tablets for 7 days. Examination and observation of all participants was done for up to 14 days after the first intake of the study drug. The effect of treatment was assessed by subjective reporting of the symptoms of ARVI and influenza, using a predefined symptom scale score system. Objective assessment was performed by measuring vitals signs, laboratory tests (including blood and urine assessment), as well as evaluating the immune status (including measuring the relative concentration of interferon and immunoglobulins).

Detailed description

Numerous studies have shown that influenza vaccines, prepared against the relevant epidemic seasonal vaccine strains, are an effective remedy in prevention of this mass disease and are able to protect about 80% of otherwise healthy children and adults. However, to develop vaccines against the emerging new pandemic strain of the influenza virus and produce them in the necessary amounts requires at least 6 months. During such interim periods, sufficient protection of the population is essential by effective measures for treatment and prevention of influenza. This randomized, single-blind, clinical study was conducted to investigate the clinical efficacy and safety of the drug Amizon (N-methyl-4-benzylcarbamidopyridinium iodide, international nonproprietary name enisamium iodide) compared with placebo, for the treatment of patients with ARVI, including influenza. Enisamium iodide is an antiviral small molecule. Enisamium can directly inhibit influenza viral RNA replication. The study design was: randomised, single-blind, 2 parallel groups. Adult patients (18-60 y) with symptoms of ARVI, including influenza took either Amizon tablets (active ingredient enisamium iodide) for 7 days; in the control group patients took placebo tablets for 7 days. Study visits occurred on Day 0 (screening, examination, check inclusion/exclusion criteria, enrollment, randomization, and first intake of study drug); further study visits were on Day 3, Day 7, and Day 14. The effect of treatment was assessed by questioning the patients regarding ARVI and influenza symptoms that included pain, headache, general weakness, sore throat, pain in the joints, fatigue, runny and itchy nose. The severity of symptoms was recorded using a 4-point Likert scale. Further evaluation of the treatment was performed by measuring the vitals signs, laboratory tests that included blood and urine analysis, biochemical analysis, as well as assessing the immune status (including measuring the absolute lymphocytes count, and evaluating the relative concentration of interferon (IFN)-alpha and IFN-gamma, and immunoglobulin (Ig) A, M, and G (IgA, IgM, and IgG).

Interventions

Patients ingested Amizon tablets without chewing, after meal, as follows: 2 tablets (total dose 500 mg) 3 times a day, for 7 days. Each tablet contains 250 mg of Nmethyl-4-N-methyl-4-benzylcarbamidopyridinium iodide (INN enisamium iodide).

DRUGPlacebo

Patients ingested placebo tablets without chewing, after meal, in the dose 500 mg (2 tablets), 3 times a day, for 7 days.

Objective symptoms of acute respiratory viral infection (ARVI), including influenza, were monitored: fever, pharyngeal hyperemia, rhinitis, arterial blood pressure, enlarged lymph nodes, auscultation findings for lung and heart. Clinical improvement was assessed by the investigator, relating to the severity of clinical symptoms of acute respiratory viral infection (ARVI), including influenza. A score system used to assess participants' health. A higher score implies worse outcome. Objective symptoms scores were: normal or abnormal blood pressure: 0 or 4 score points; lung auscultation: 0 points; vesicular breath sound and wheezing or crepitation 2 or 4 points, respectively; clear and rhythmic heart sounds -- each 0 points; noisy and arrhythmic heart sounds -- each 2 score points.

Efficacy: Objective Clinical Sum Score

Objective clinical sum score. Objective symptoms of acute respiratory viral infection (ARVI), were monitored. For the objective clinical sum score, clinical status was assessed by the investigator, relating to the severity of clinical symptoms of ARVI, including influenza. A score system (score points) that was used to assess participants' health, was based on objective symptoms scores, shown below. * Blood pressure: normal=0 points; abnormal=4 points. * Lung auscultation: vesicular breath sound=0 points; wheezing=2 points; crepitation=4 points. * Heart sound; clear heart sounds=0 points; rhythmic heart sounds=0 points; noisy heart sounds=2 points; arrhythmic heart sounds=2 points. A higher score implies worse clinical outcome.

Time frame: Day 0 (baseline), 3, 7, 14.

Efficacy: Subjective Symptom Sum Score (4-point Likert Scale)

Subjective symptom sum score. Subjective symptoms of acute respiratory viral infection (ARVI) including influenza, that were monitored: elevated body temperature, chills, cough, headache, myalgia, sore throat, weakness. The subjective symptoms were assessed using a 4-point Likert scale for the individual assessment of the severity of the above 7 symptoms, ranging from absent (0), mild (1), moderate (2), or severe (3). A higher score implies worse outcome.

Time frame: Day 0 (baseline), 3, 7, 14.

Population: Intention-to-treat. All randomized patients who received at least one dose of study medication.
