Ozenoxacin is a topical antibiotic approved in the United States for treatment of impetigo in adults and children age ≥2 months. This analysis evaluated the efficacy and safety of ozenoxacin in specific pediatric age groups.
Data for children aged 2 months to <18 years recruited from eight countries who had participated in phase 1 and 3 trials of ozenoxacin were extracted and analyzed by age range.
Across studies, 644 pediatric patients with impetigo received ozenoxacin 1% cream (n = 287) or vehicle (n = 247). One study included retapamulin 1% ointment as the internal validity control (n = 110). The clinical success rate at the end of treatment and bacterial eradication rates after 3 to 4 days of treatment and at the end of treatment were significantly higher with ozenoxacin than vehicle (all < .0001). The clinical and microbiologic success rates were higher with ozenoxacin than vehicle in the age groups of 0.5 to <2 years, 2 to <6 years, 6 to <12 years, and 12 to <18 years and were comparable to vehicle in the 2 to <6 months age group, although patient numbers were low (≤5 per treatment arm). No safety concerns with ozenoxacin were identified. Of the 362 plasma samples derived from 38 patients, four slightly exceeded the lower limit of quantification, indicating negligible systemic absorption.
The results of this analysis suggest that ozenoxacin 1% cream is an effective and safe treatment for impetigo in pediatric patients aged 2 months to <18 years.
奥昔沙星是一种在美国获批用于治疗2个月及以上成人和儿童脓疱病的外用抗生素。本分析评估了奥昔沙星在特定儿科年龄组中的疗效和安全性。
从八个国家招募的参与奥昔沙星1期和3期试验的2个月至未满18岁儿童的数据,按年龄范围进行提取和分析。
在各项研究中,644例脓疱病儿科患者接受了1%奥昔沙星乳膏(n = 287)或赋形剂(n = 247)治疗。一项研究纳入1%瑞他帕林软膏作为内部有效性对照(n = 110)。治疗结束时的临床成功率以及治疗3至4天后和治疗结束时的细菌清除率,奥昔沙星组均显著高于赋形剂组(均P <.0001)。在0.5至未满2岁、2至未满6岁、6至未满12岁和12至未满18岁年龄组中,奥昔沙星组的临床和微生物学成功率高于赋形剂组,在2至未满6个月年龄组中与赋形剂组相当,不过该年龄组患者数量较少(每个治疗组≤5例)。未发现奥昔沙星存在安全性问题。在来自38例患者的362份血浆样本中,有4份略超过定量下限,表明全身吸收可忽略不计。
本分析结果表明,1%奥昔沙星乳膏是治疗2个月至未满18岁儿科患者脓疱病的一种有效且安全的疗法。
