Abstract
Study Goals.Assessment of the efficacy and safety of the Pentanedioic Acid Imidazolyl Ethanamide (IPA) in the treatment of influenza and other acute respiratory viral infections (ARVI) in children aged 3–6 years.Children Characteristics and Study Methods.The randomized double-blind placebo-controlled multicenter clinical study involving 190patients aged 3–6 years was carried out as follows: 95 patients received IPA at 30 mg/day dose once for 5 days and 95 patients – placebo using the same pattern. The therapy efficacy was assessed by the body temperature, dynamics of the individual symptoms of thedisease as per the Severity Scale for the patients with influenza and other acute respiratory viral infections (Scale) and the incidencerate of complications of the acute respiratory viral infections. The primary endpoint is the period of the score reduction on the Scale to 2points, providing that there is not more than 1 score on the individual subscales with the body temperature normalization from the startof treatment. The safety analysis was carried out using the assessment of the nature and incidence rate of the adverse events.Results.The IPA use at 30 mg/day dose significantly promotes the achievement of goals for the primary endpoint – the averagevalue in the IPA group is 91.79 h (95% confidence interval – CI from 87.45 to 96.13), in the placebo group – 100.12 h (95% CIfrom 96.73 to 103.51). In the IPA group, the body temperature returned to normal by 18.56 h faster in average compared with theplacebo. The regression of the catarrhal and intoxication symptoms was significantly promoted with the IPA use as follows: by the3rd day of the therapy, the average score on the Scale was 5.22 points for IPA, and it was statistically significantly lower than thatin the placebo group – 6.21 points. The comparative analysis of the incidence rate of adverse events did not reveal the statisticallysignificant differences between IPA and placebo. None of the adverse events recorded was clinically significant, and none caused thecancellation or change in the dosage of the study drug.Conclusions.IPA broad-spectrum antiviral drug at 30 mg/day dose has demonstrated the high efficacy in the treatment of the acute respiratory viral infections of various etiologies in children aged 3–6 years. The IPA use compared with the placebo causes the significant reduction of the fever period, accelerates the relief of the intoxication and catarrhal symptoms, and decreases the recoverytime. The IPA is characterized by high tolerability and high safety, which allows to recommend the drug for the treatment of influenzaand ARVI (acute respiratory viral infections) in children from 3 years of age.
Highlights
Применение ИПК в дозе 30 мг/сутки достоверно ускоряет достижение целей по первичной конечной точке (среднее значение в группе ИПК – 91,79 ч (95% доверительных интервалов (ДИ) от 87,45 до 96,13), в группе плацебо – 100,12 ч (95% ДИ от 96,73 до 103,51)

Summary
IPA broad-spectrum antiviral drug at 30 mg/day dose has demonstrated the high efficacy in the treatment of the acute respiratory viral infections of various etiologies in children aged 3–6 years. Незавершенное формирование иммунной системы у детей в возрасте до 3 лет приводит к низкому уровню ключевых защитных Т-клеточных цитокинов противовирусного ответа IL-4 и IL-10 [10], а также сопровождается дефектами дифференцировки B-лимфоцитов в клетки памяти, продуцирующие IgA, что существенно снижает напряженность постинфекционного иммунитета [11]. Опасность гриппа и других ОРВИ обусловлена риском развития вторичных бактериальных осложнений и микст-инфекций, которые протекают значительно тяжелее и дольше, чем моноинфекции, что может иметь особое значение у детей дошкольного возраста [12, 13]. Цель исследования: оценка эффективности и безопасности ИПК в дозе 30 мг/сут в сравнении с плацебо при лечении гриппа и других ОРВИ у детей в возрасте 3–6 лет
