- Change in Best Ear Hearing Assessments at 6 Months. [ Time Frame: Between baseline and 6 months ]Hearing assessment was evaluated by an independent audiologist. At baseline, a brainstem evoked response (BSER) assessment and autoacoustic emissions (OAEs) hearing assessments were obtained. At 6 months, BSER and /or Visual reinforcement audiometry (VRA) and OAEs were obtained. A single, independent study audiologist who was blinded to treatment assignment assessed the audiology test battery for each subject and assigned the classifications of normal hearing, mild hearing loss, moderate hearing loss, or severe hearing loss based upon their hearing thresholds (in decibels). The classifications were assigned by ear (one for the left ear and one for the right ear), giving "total ear" classifications. Following this, the study audiologist assigned the "best ear" classification for the subject at that study visit; for example, if a subject had mild hearing loss in their left ear and severe hearing loss in their right ear, then the "best ear" classification was mild hearing loss.
- Adverse Events Which Lead to Permanent Discontinuation of Valganciclovir Therapy or Lead to Irreversible Outcome of the Adverse Event. [ Time Frame: baseline through 7 months ]Adverse events were assessed at each visit through month 7 of the study. No subject discontinued valganciclovir therapy due to permanent discontinuation of valganciclovir therapy or lead to irreversible outcome of any adverse event.
- Change in Best Ear Hearing Assessments at 12 Months. [ Time Frame: Between baseline and 12 months ]Hearing assessment was evaluated by an independent audiologist. At baseline, a brainstem evoked response (BSER) assessment and autoacoustic emissions (OAEs) hearing assessments were obtained.

Following this, the study audiologist assigned the "best ear" classification for the subject at that study visit; for example, if a subject had mild hearing loss in their left ear and severe hearing loss in their right ear, then the "best ear" classification was mild hearing loss.
- Change in Best Ear Hearing Assessments at 24 Months. [ Time Frame: Between baseline and 24 months ]Hearing assessment was evaluated by an independent audiologist.
