研究目的: |
通过多中心、开放性、随机对照研究,评估 OM-85 联合皮下特异性免疫治疗(SCIT)在尘螨过敏性儿童哮喘中的临床疗效与安全性,重点观察其对哮喘急性发作率的影响;同时比较不同 OM-85 疗程方案的疗效差异,并从免疫学角度探讨联合治疗对 Th1/Th2 免疫平衡、免疫耐受相关指标及体液免疫的调节作用,为优化儿童过敏性哮喘的长期免疫治疗策略提供循证依据。 |
||||||||||||||||||||||
|
Objectives of Study: |
To evaluate the efficacy and safety of OM-85 combined with subcutaneous allergen immunotherapy (SCIT) in children with house dust mite–induced asthma through a multicenter, open-label, randomized controlled trial, with a primary focus on asthma exacerbation rates. The study also aims to compare different OM-85 treatment regimens and to explore the immunological effects of the combined therapy on Th1/Th2 balance, immune tolerance–related markers, and humoral immunity. |

药物成份或治疗方案详述: |
本研究采用皮下特异性免疫治疗(subcutaneous allergen immunotherapy,SCIT)联合免疫调节剂 OM-85 的治疗方案。所有受试者在研究期间均接受符合全球哮喘防治创议(GINA)指南的标准哮喘基础治疗。 SCIT 治疗方案: 使用标准化屋尘螨变应原制剂,按照药品说明书及临床规范实施递增期和维持期皮下注射治疗,由具备资质的专科医师和专科护士操作,并在给药后进行常规安全监测。 OM-85 治疗方案: OM-85 为口服细菌溶解产物类免疫调节剂,给药方式为口服,每日 1 粒,每月连续服用 10 天。 受试者根据随机分组接受以下治疗方案: A 组: SCIT 联合 OM-85 单疗程治疗(连续 3 个月); B 组: SCIT 联合 OM-85 双疗程治疗(连续 3 个月,停用 6 个月后再连续 3 个月); C 组: SCIT 单用对照组,不使用 OM-85。 研究过程中对所有受试者进行统一随访管理,并在规定时间点评估临床疗效、免疫学指标及安全性。不良事件和严重不良事件将按研究方案进行记录和处理。 |

Description for medicine or protocol of treatment in detail: |
This study adopts a treatment strategy combining subcutaneous allergen immunotherapy (SCIT) with the immunomodulatory agent OM-85. All participants will receive standard asthma management in accordance with the recommendations of the Global Initiative for Asthma (GINA) guidelines throughout the study period. SCIT regimen: Standardized house dust mite allergen extracts will be administered by subcutaneous injection following the approved product instructions and established clinical protocols, including an up-dosing phase and a maintenance phase. All injections will be performed by qualified specialist physicians and nurses, with routine post-injection safety monitoring. OM-85 regimen: OM-85 is an oral bacterial lysate–based immunomodulatory agent. It will be administered orally at a dose of one capsule per day for 10 consecutive days each month. Participants will receive one of the following treatment regimens according to randomization: Group A: SCIT combined with a single course of OM-85 (continuous treatment for 3 months); Group B: SCIT combined with a double course of OM-85 (3 months of treatment, followed by a 6-month interval, and an additional 3 months of treatment); Group C: SCIT alone as the control group, without OM-85 administration. All participants will undergo standardized follow-up according to the study protocol. Clinical outcomes, immunological parameters, and safety outcomes will be assessed at predefined time points. Adverse events and serious adverse events will be recorded and managed in accordance with the study protocol. |

随机方法(请说明由何人用什么方法产生随机序列): |
随机序列由独立的数据管理人员采用计算机随机数生成方法产生,并按照 1:1:1 的比例分配至三个研究组(A 组:SCIT 联合 OM-85 单疗程组;B 组:SCIT 联合 OM-85 双疗程组;C 组:SCIT 单用对照组)。随机分配序列由数据管理中心保存,研究者在受试者完成筛选并符合入组条件后,根据随机序列进行分组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
The randomization sequence will be generated by an independent data manager using a computer-generated random number method. Participants will be allocated in a 1:1:1 ratio to three study groups (Group A: SCIT plus a single course of OM-85; Group B: SCIT plus a double course of OM-85; Group C: SCIT alone as the control group). The randomization list will be maintained by the data management center, and investigators will assign participants to treatment groups after eligibility confirmation. |

盲法: |
本研究为开放性随机对照研究,研究对象及研究人员均不实施盲法。为减少评估偏倚,主要终点及部分客观指标的统计分析将由独立研究人员在盲态条件下完成,数据分析人员在分析过程中不知晓受试者的分组信息。 |
|
Blinding: |
This study is designed as an open-label randomized controlled trial. Therefore, neither participants nor investigators will be blinded to the treatment allocation. To minimize potential assessment bias, the analysis of the primary outcome and selected objective endpoints will be conducted by independent evaluators who are blinded to the treatment allocation during data analysis. |
