Brief Summary:

The overall goal of this study is to determine the clinical benefit and safety of antiviral therapy for asymptomatic congenital cytomegalovirus (cCMV) infected hearing-impaired infants. We will conduct a multi-center double-blind randomized placebo-controlled trial to determine whether hearing-impaired infants with asymptomatic cCMV have better hearing and language outcomes if they receive valganciclovir antiviral treatment. We will also determine the safety of antiviral valganciclovir therapy for asymptomatic cCMV-infected hearing impaired infants. This study will be unique in that the cohort enrolled will only include hearing-impaired infants with asymptomatic cCMV.

Primary Objective: To determine if treatment of cCMV-infected hearing impaired infants with isolated hearing loss with the antiviral drug valganciclovir reduces the mean slope of total hearing thresholds over the 20 months after randomization compared to untreated cCMV-infected infants with isolated hearing loss.

Main Secondary Objectives:

  1. To determine if valganciclovir treatment improves the following outcomes when compared to the control group:

    1. The slope of best ear hearing thresholds over the 20 months after randomization.
    2. The MacArthur-Bates Communicative Development Inventory (CDI) percentile score for words produced at 20 months of age.
  2. To evaluate safety measures based on all grade 3 or greater new adverse events designated by the NIAID Division of AIDS (DAIDS) toxicity tables.

Detailed Description:

Cytomegalovirus (CMV) can be transmitted from the mother to the fetus and is a leading cause of sensorineural hearing loss (SNHL), which is a condition where the inner ear is unable to convert sound into nerve impulses to the brain. This hearing loss and its detrimental effect on language development contribute nearly $4 billion annually to the health care costs in the U.S. Unlike other types of SNHL, CMV induced hearing loss can be treated. Several clinical trials have demonstrated that antiviral therapy may prevent progressive hearing loss if administered early in life for severely affected (symptomatic CMV) infants. These promising findings have given rise to a debate regarding the best method for identifying and treating the more numerous asymptomatic CMV-infected infants.

One approach is to conduct universal newborn hearing screens, and then do CMV diagnostic testing only on the infants who fail the hearing screen. This targeted approach should identify those infants at greatest risk of developing progressive hearing loss and consequent communicative difficulties. Utah is the first state to mandate this approach whereby infants under three weeks of age who fail their newborn hearing screening undergo CMV testing. In this trial, the hearing screen targeted approach will be used to identify patients eligible for participation in a double blind placebo controlled randomized clinical trial of antiviral valganciclovir therapy. The results of this trial will inform public policy, potentially shift our current clinical practice regarding pediatric hearing loss evaluation, and potentially offer a therapeutic option to asymptomatic CMV-infected infants with SNHL.

Primary Outcome Measures :
  1. Total Ear Hearing Slope [ Time Frame: Assessed at baseline, 8, 14 and 20 months post-randomization ]
    The primary objective of this randomized trial is to determine if treatment of cCMV-infected infants with isolated hearing loss with the antiviral drug valganciclovir reduces the slope of the total ear hearing thresholds over the 20 months after randomization compared to that of untreated cCMV-infected infants with isolated hearing loss.


Secondary Outcome Measures :
  1. Best Ear Hearing Slope [ Time Frame: Assessed at baseline, 8, 14 and 20 months post-randomization ]
    The computation of the slope of the best-ear hearing thresholds begins with the same preliminary averaging steps across MRLs and truncation of threshold levels to between 15 and 110 dB as is described above for the total ear hearing slope, but in this case the analysis is based on the best-ear hearing score at each time point.

  2. Percentile Score for Words Produced Endpoint [ Time Frame: Assessed at 20 months of age ]
    The main communicative development endpoint will be determined based on the MacArthur-Bates CDI words produced percentile score given at 20 months of age.


Other Outcome Measures:
  1. Words Produced Below 10th Percentile [ Time Frame: 14 and 20 month of age assessments ]
    Dichotomous endpoint defined by children's communicative competency as above or below the 10th percentile based upon on the number of words produced.

  2. Additional MacArthur Bates - Words and Sentences Subscale Percentiles [ Time Frame: 20 month of age assessment ]
    The percentile scores for the MacArthur Bates Communicative Development Inventory Words and Sentences for complexity and the word form subscales, and the mean length utterance.

  3. MacArthur Bates - Words and Gestures Subscale Percentiles [ Time Frame: 14 months of age assessment ]
    Secondary communicative development endpoints will be obtained from parent report on the MacArthur Bates Communicative Development Inventory - Words and Gestures form at 14-months. The scores will be the percentile scores for the total number of words produced, total gestures, phrases understood and words understood.

  4. Developmental Domain Endpoints [ Time Frame: 14 and 20 months of age assessments ]
    Based on parent report on the Ages and Stages Questionnaire, 3rd Edition. There are five subtests on the ASQ-3. These include communication, gross motor, fine motor, problem solving, and personal- social. We will use the following scores:1)Raw scores from each subtest 2)Dichotomous endpoints for each subtest based upon the raw score above or below a designated cut-off score based upon age

  5. Valganciclovir Pharmacokinetics [ Time Frame: From week 2 to month 6 post-randomization ]
    Valganciclovir drug levels will be measured.

  6. Viral Resistance [ Time Frame: Assessed at month 7 post-randomization ]
    The presence of viral resistance will be measured.

  7. Viral Load [ Time Frame: Assessed at baseline month 3, and month 7 post-randomization ]
    Viral load will be measured

  8. LittlEARS [ Time Frame: 14 and 20 months of age assessments ]
    The raw scores will be dichotomized based on the child's hearing age and compared to standardized scores.
