Clinical Trial 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.

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.

Intervention

Drug:
• Valganciclovir
Valganciclovir is supplied as a powder for reconstitution into an oral solution. The reconstituted solution formulation comprises the following excipients: Povidone K30, fumaric acid, sodium benzoate, saccharin sodium, mannitol, flavor, and purified water.
• Simple Syrup
Simple Syrup contains sucrose 85% weight by volume, purified water, and methyl paraben as a preservative along with natural preservatives. It will be flavored to match the flavor of valganciclovir.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Words Produced Below 10th Percentile	Dichotomous endpoint defined by children's communicative competency as above or below the 10th percentile based upon on the number of words produced.	14 and 20 month of age assessments
Other	Additional MacArthur Bates - Words and Sentences Subscale Percentiles	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.	20 month of age assessment
Other	MacArthur Bates - Words and Gestures Subscale Percentiles	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.	14 months of age assessment
Other	Developmental Domain Endpoints	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	14 and 20 months of age assessments
Other	Valganciclovir Pharmacokinetics	Valganciclovir drug levels will be measured.	From week 2 to month 6 post-randomization
Other	Viral Resistance	The presence of viral resistance will be measured.	Assessed at month 7 post-randomization
Other	Viral Load	Viral load will be measured	Assessed at baseline month 3, and month 7 post-randomization
Other	LittlEARS	The raw scores will be dichotomized based on the child's hearing age and compared to standardized scores.	14 and 20 months of age assessments
Primary	Total Ear Hearing Slope	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.	Assessed at baseline, 8, 14 and 20 months post-randomization
Secondary	Best Ear Hearing Slope	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.	Assessed at baseline, 8, 14 and 20 months post-randomization
Secondary	Percentile Score for Words Produced Endpoint	The main communicative development endpoint will be determined based on the MacArthur-Bates CDI words produced percentile score given at 20 months of age.	Assessed at 20 months of age
