缬更昔洛韦治疗巨细胞病毒感染听障婴儿的随机对照试验 (ValEAR)
Valganciclovir 用于巨细胞病毒感染的听力受损婴儿的随机对照试验:ValEAR 试验
本研究的总体目标是确定抗病毒治疗对无症状先天性巨细胞病毒 (cCMV) 感染的听力受损婴儿的临床益处和安全性。 我们将进行一项多中心双盲随机安慰剂对照试验,以确定如果接受缬更昔洛韦抗病毒治疗,患有无症状 cCMV 的听力受损婴儿是否有更好的听力和语言结果。 我们还将确定抗病毒药物缬更昔洛韦治疗无症状 cCMV 感染听力受损婴儿的安全性。 这项研究的独特之处在于,纳入的队列将仅包括患有无症状 cCMV 的听力受损婴儿。
主要目的:确定与未治疗的单独听力损失的 cCMV 感染婴儿相比,使用抗病毒药物缬更昔洛韦治疗单独听力损失的 cCMV 感染听力受损婴儿在随机分组后 20 个月内是否降低了总听力阈值的平均斜率。
主要次要目标:
为了确定与对照组相比,缬更昔洛韦治疗是否改善了以下结果:
- 随机分组后 20 个月内最佳耳朵听力阈值的斜率。
- MacArthur-Bates Communicative Development Inventory (CDI) 在 20 个月大时产生的单词百分位分数。
- 根据 NIAID 艾滋病分部 (DAIDS) 毒性表指定的所有 3 级或更高级别的新不良事件评估安全措施。

详细说明
巨细胞病毒 (CMV) 可以从母亲传播给胎儿,是感音神经性听力损失 (SNHL) 的主要原因,这是一种内耳无法将声音转化为大脑神经冲动的疾病。 这种听力损失及其对语言发展的不利影响每年为美国的医疗保健费用贡献近 40 亿美元。与其他类型的 SNHL 不同,CMV 引起的听力损失是可以治疗的。 几项临床试验表明,如果在生命早期对受严重影响(有症状的 CMV)的婴儿进行抗病毒治疗,可以预防进行性听力损失。 这些有希望的发现引发了关于识别和治疗更多无症状 CMV 感染婴儿的最佳方法的争论。
一种方法是对新生儿进行普遍的听力筛查,然后仅对未通过听力筛查的婴儿进行 CMV 诊断测试。 这种有针对性的方法应确定那些最有可能发展为进行性听力损失和随之而来的交流困难的婴儿。 犹他州是第一个强制执行这种方法的州,即未通过新生儿听力筛查的三周龄以下婴儿接受 CMV 检测。 在该试验中,听力筛查靶向方法将用于确定有资格参与抗病毒缬更昔洛韦治疗的双盲安慰剂对照随机临床试验的患者。 该试验的结果将为公共政策提供信息,可能会改变我们目前关于儿科听力损失评估的临床实践,并可能为无症状的 CMV 感染的 SNHL 婴儿提供治疗选择。

MacArthur-Bates Communicative Development Inventories (CDI): Words Produced Percentile Score
大体时间:20 months of age

The MacArthur-Bates Communicative Development Inventories (CDI) Words Produced subscale is a parent-reported measure of expressive language development.
Percentile scores range from 0 to 100, with higher percentile scores indicating better expressive language performance.

Words Produced Below 10th Percentile
大体时间:14 and 20 months of age assessments
|
Participants were classified according to whether their MacArthur-Bates Communicative Development Inventories (CDI) Words Produced percentile score was below the 10th percentile.
Scores below the 10th percentile indicate increased risk for expressive language delay.
The study was terminated early because of slow enrollment; therefore, the prespecified efficacy analyses were not performed, and only descriptive summaries of available data are reported.

MacArthur-Bates CDI: Words and Sentences Subscale Percentiles
大体时间:20 months of age
|
The MacArthur-Bates Communicative Development Inventories (CDI) Words and Sentences subscales assess expressive language development.
This outcome summarizes the Complexity, Word Forms, and Mean Length of Utterance percentile scores.
Percentile scores range from 0 to 100, with higher scores indicating better expressive language performance.

LittlEARS Auditory Questionnaire Score
大体时间:Assessments performed at 14 and 20 months of age
|
The LittlEARS Auditory Questionnaire is a parent-reported measure of auditory development in young children.
Raw scores range from 0 to 35, with higher scores indicating better auditory development.
Normative values vary by age.
Because the study was terminated early by the National Institute on Deafness and Other Communication Disorders (NIDCD) due to slow enrollment, the target sample size was not achieved and the prespecified inferential efficacy analyses were not performed.
Only descriptive summaries of available participant data are reported.

Developmental Domain Endpoints
大体时间:20 months of age
|
The Ages and Stages Questionnaire, Third Edition (ASQ-3) is a parent-completed developmental screening instrument that evaluates five developmental domains: Communication, Gross Motor, Fine Motor, Problem Solving, and Personal-Social.
Each domain is scored separately; higher scores indicate better developmental performance within that domain.
Because the study was terminated early by the National Institute on Deafness and Other Communication Disorders (NIDCD) due to slow enrollment, the target sample size was not achieved and the prespecified inferential efficacy analyses were not performed.
No ASQ-3 outcome data are reported.

Valganciclovir Pharmacokinetics
大体时间:From week 2 to month 6 post-randomization
|
Pharmacokinetic (PK) blood samples were collected between Week 2 and Month 6 after randomization to characterize valganciclovir exposure.
Because the study was terminated early by the National Institute on Deafness and Other Communication Disorders (NIDCD) due to slow enrollment, the planned PK assays were not completed before study closure.
Therefore, no pharmacokinetic results are available for reporting.

Number of Participants With Viral Resistance Results
大体时间:Month 7 post-randomization
|
Viral resistance testing was planned to evaluate the development of cytomegalovirus (CMV) resistance mutations following valganciclovir treatment.
Because the study was terminated early by the National Institute on Deafness and Other Communication Disorders (NIDCD) due to slow enrollment, the planned viral resistance assays were not completed before study closure.
Therefore, no viral resistance results are available for reporting.

Viral Load
大体时间:Assessed at baseline, Month 3, and Month 7 post-randomization
|
Cytomegalovirus (CMV) viral load testing was planned at baseline, Month 3, and Month 7 after randomization to assess CMV viral burden during and after treatment.
Because the study was terminated early by the National Institute on Deafness and Other Communication Disorders (NIDCD) due to slow enrollment, the planned viral load assays were not completed before study closure.
Therefore, no viral load results are available for reporting.

LittlEARS Auditory Questionnaire Score
大体时间:20 months of age (planned assessment)
|
The LittlEARS Auditory Questionnaire is a parent-reported measure of auditory development in young children.
Raw scores range from 0 to 35, with higher scores indicating better auditory development.
Because the study was terminated early by the National Institute on Deafness and Other Communication Disorders (NIDCD) due to slow enrollment, the target sample size was not achieved and the prespecified inferential efficacy analyses were not performed.
No analyzable LittlEARS outcome data were available for reporting.
