Study No. 84158 – a multicenter, randomized, double-blind, phase III, active control study of no less efficiency in two parallel groups of adult patients (mean age: 41.3 and 41.88 years) with acute non-specific LBP. From 05.09.2017 to 07.05.2018, 239 patients with acute non-specific LBP were included in the study. The two placebo method was used to mask the prescribed treatment. Inpatients or outpatients were randomly assigned to therapy with PRTH 450 once a day in combination with placebo three times a day or TH 150 three times a day in combination with placebo once a day.For 14 days, after a meal, patients received oral PRTH 450 once a day as an active drug and placebo three times per day or oral TH 150 three times per day and placebo once a day. Follow-up visits were carried out after 3.7±1 and 14±2 days. Patients in whom the study drugs did not significantly reduce pain were allowed to additionally use diclofenac tablets up to 50 mg three times a day. The primary efficacy endpoint was the percentage change in baseline disability assessed by the Roland-Morris Disability Questionnaire (RMQ) at 14 days (treatment completion). Secondary efficacy endpoints were the percentage change in baseline disability after 3 and 7 days, the difference in pain intensity on the visual analogue scale (VAS) after 3, 7, and 14 days, the patient's overall impression of the daily change in his condition, the time before symptoms began to decrease, change in range of motion, measured by the fingertips to floor distance during an attempt to reach for the floor with the fingertips after 3, 7 and 14 days, as well as the total dose of diclofenac for additional pain relief. Safety indicators and their changes were assessed at each visit and in each treatment group. The presence of adverse events (AEs) was determined based on patient complaints and general examination results, measurements of vital signs (blood pressure, heart rate), 12-lead electrocardiography results, and blood and urine tests throughout the study.Results and discussion. In 14 days, the limitation of daily activity according to RMQ decreased by 80.5±18.19% in the PRTH 450 group and by 78.9±15.79% in the TH 150 group, after 3 days – by 21.9±17.07 and 19,9±15.72%, respectively. There was a significant decrease in pain at rest and during movement according to the VAS during treatment, as well as an increase in the range of motion in the lumbar spine in both groups. During the follow-up period, patients took an average of 15.1 tablets of diclofenac in the PRTH 450 group and 16.1 tablets in the TH 150 group. At the end of the study, 74.3% of patients in the PRTH 450 group and 70.9% of patients in the TH 150 group noted a «marked improvement» on the scale of the overall assessment of their condition. 21 AEs in 16 (13.4%) patients in the PRTH 450 group and 23 AEs in 21 (17.5%) patients in the TH 150 group were registered. No statistically significant differences were found between the two groups for the primary study endpoint (p=0.475, Fisher's exact test), AEs, and for all secondary study endpoints. Conclusion. The results of the study showed that in acute nonspecific LBP, PRTH 450 (Mydocalm® Long) administered once daily has no less efficacy and safety than TH 150 (Mydocalm®).</p></abstract><trans-abstract xml:lang="ru"><p>Толперизона гидрохлорид пролонгированного высвобождения 450 мг (ТГПВ 450) представляет собой лекарственную форму, которая удобна для пациентов, поскольку снижает частоту приема препарата в сутки: с трех таблеток по 150 мг с немедленным высвобождением (ТГ 150) до одной таблетки ТГПВ 450.</p><p>Цель исследования – оценить терапевтическую эффективность и безопасность новой лекарственной формы ТГПВ 450 (прием один раз в сутки) в сравнении с ТГ 150 (Мидокалм® прием три раза в сутки) при острой неспецифической боли в нижней части спины (БНЧС).</p><sec><title>Пациенты и методы</title><p>Пациенты и методы. Исследование № 84158 – многоцентровое рандомизированное двойное слепое исследование не меньшей эффективности III фазы с активным контролем в двух параллельных группах взрослых пациентов (средний возраст – 41,3 и 41,88 года) с острой неспецифической БНЧС. В период с 05.09.2017 г. по 07.05.2018 г. в исследование были включены 239 пациентов с острой неспецифической БНЧС. Для маскировки назначенного лечения применяли метод двух плацебо. Стационарным или амбулаторным пациентам случайным образом была назначена терапия ТГПВ 450 один раз в сутки в комбинации c плацебо три раза в сутки или ТГ 150 (Мидокалм®) три раза в сутки в комбинации c плацебо один раз в сутки.</p><p>Пациенты в течение 14 сут получали после приема пищи внутрь ТГПВ 450 один раз в сутки в качестве активного препарата и плацебо три раза в сутки или внутрь ТГ 150 (Мидокалм®) три раза в сутки и плацебо один раз в сутки. Повторные обследования проведены через 3, 7±1 и 14±2 сут. Пациентам, у которых исследуемые препараты существенно не уменьшали боль, разрешалось дополнительно применять диклофенак в таблетках до 50 мг три раза в сутки. Первичной конечной точкой эффективности было процентное изменение исходного ограничения жизнедеятельности по шкале функциональных нарушений Роланда–Морриса (ШРМ) через 14 сут (завершение лечения). Вторичными конечными точками эффективности были процентное изменение исходного ограничения жизнедеятельности через 3 и 7 сут, изменение интенсивности боли по визуальной аналоговой шкале (ВАШ) через 3, 7 и 14 сут, общее впечатление пациента о ежедневном изменении своего состояния, время до начала уменьшения симптомов, изменение объема движений, измеренное по расстоянию от кончиков пальцев до пола при попытке достать пальцами пола через 3, 7 и 14 сут, а также суммарная доза диклофенака для дополнительного обезболивания. Показатели безопасности и их изменения оценивали во время каждого визита и в каждой терапевтической группе. Наличие нежелательных явлений (НЯ) определяли на основании жалоб пациентов и результатов общего осмотра, измерения показателей жизненно важных функций (артериальное давление, частота сердечных сокращений), результатов электрокардиографии в 12 отведениях и анализов крови и мочи в ходе всего исследования.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Через 14 сут ограничение жизнедеятельности по ШРМ уменьшилось на 80,5±18,19% в группе ТГПВ и на 78,9±15,79% в группе ТГ, через 3 сут – соответственно на 21,9±17,07 и 19,9±15,72%. В обеих группах отмечены существенное снижение боли по ВАШ в покое и при движении на фоне лечения, а также увеличение объема движений в поясничном отделе. В период наблюдения пациенты приняли в среднем 15,1 таблетки диклофенака в группе ТГПВ 450 и 16,1 таблетки в группе ТГ 150. В конце исследования 74,3% пациентов в группе ТГПВ 450 и 70,9% пациентов в группе ТГ отметили «выраженное улучшение» по шкале общей оценки своего состояния. Было зарегистрировано 21 НЯ у 16 (13,4%) пациентов в группе ТГПВ и 23 НЯ у 21 (17,5%) пациента в группе ТГ. Статистически значимых различий между двумя группами не было выявлено по первичной точке исследования (p=0,475, точный критерий Фишера), НЯ и по всем вторичным точкам исследования.</p></sec><sec><title>Заключение</title><p>Заключение. Результаты исследования показали, что при острой неспецифической БНЧС ТГПВ 450, принимаемый один раз в сутки, обладает не меньшей эффективностью и безопасностью, чем зарегистрированный препарат ТГ 150 (Мидокалм®).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>острая неспецифическая боль в нижней части спины</kwd><kwd>толперизона гидрохлорид пролонгированного высвобождения 450 мг</kwd><kwd>толперизона гидрохлорид (Мидокалм®) 150 мг</kwd><kwd>эффективность</kwd><kwd>безопасность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute non-specific lower back pain</kwd><kwd>prolonged release tolperisone hydrochloride 450 mg (Mydocalm® Long)</kwd><kwd>tolperisone hydrochloride (Mydocalm®) 150 mg</kwd><kwd>efficacy</kwd><kwd>safety</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья спонсируется компанией ООО «Гедеон Рихтер Фарма».
