Short-Term vs. Long-Term Valganciclovir Therapy for Symptomatic Congenital CMV Infections

13 sierpnia 2015 zaktualizowane przez: National Institute of Allergy and Infectious Diseases (NIAID)

A Phase III, Randomized, Placebo-Controlled Blinded Investigation of Six Weeks vs. Six Months of Oral Valganciclovir Therapy in Infants With Symptomatic Congenital Cytomegalovirus Infection (CASG 112)

Cytomegalovirus (CMV) infection is known to cause hearing loss and mental retardation. The purpose of this study is to compare a 6-week course to a 6-month course of the drug valganciclovir in babies born with CMV to assess the safety and efficacy of this treatment. Participants will include 104 infants (30 days old or younger) born with CMV disease. All infants will take valganciclovir by mouth for 6 weeks. At the end of the 6 week period, subjects will be assigned by chance to receive either valganciclovir or placebo (inactive substance) to complete the 6 months of antiviral treatment. Patients will be followed for the study related evaluations of safety, changes to hearing, and developmental milestones for up to 2 years. Patients will be followed by telephone contact for an additional 3 years. Thus, participants may be involved in study related procedures for approximately 5 years.

Szczegółowy opis

This study is a multi-center, prospective, international, Phase III, randomized and blinded investigation of 6 weeks versus 6 months of oral valganciclovir therapy in babies with symptomatic congenital cytomegalovirus (CMV) disease. Following enrollment, study subjects will receive 6 weeks of oral valganciclovir. Near the end of the 6-week course, subjects will be randomized in a 1:1 fashion either to continue on valganciclovir to complete 6 months of therapy or to begin a matching placebo to complete the 6 months. Study subjects will be stratified according to whether or not there is central nervous system (CNS) involvement at study entry. During the 6-month treatment period and the 1 month thereafter, study subjects will be followed weekly for 4 weeks, then every other week for 8 weeks, then every month for 4 months. At each of these visits, safety labs will be checked, growth parameters recorded, and adverse events assessed. The dose of study medication will be adjusted for weight gain at each of these study visits. Dose adjustments may also occur as indicated per protocol for neutropenia, thrombocytopenia, or renal impairment. Whole blood will be obtained for CMV viral load at each of these visits as well. Hearing outcomes will be assessed at baseline, 6 months, 12 months and 24 months. Developmental outcomes will be assessed at 12 months and 24 months. Changes in whole blood viral load measurements will be correlated with both hearing and neurologic outcomes. In study subjects with increasing whole blood viral loads during the course of treatment, assessment for antiviral resistance may be undertaken.Safety assessments include: hematology labs, chemistry labs, physical examinations, and adverse event data performed/collected serially. Development of neutropenia will be confirmed by repeat blood testing within one week, and study drug will be held until it resolves. Efficacy assessments include: hearing assessments at baseline, 6 months, 12 months and 24 months; and neurodevelopmental assessments at 12 months and 24 months. Study objectives are: to compare the impact on hearing outcomes of 6 weeks versus 6 months of antiviral treatment with valganciclovir oral solution in infants with symptomatic congenital CMV disease; to compare the safety profile of 6 weeks versus 6 months of antiviral therapy with valganciclovir oral solution in infants with symptomatic congenital CMV disease; to compare the impact on neurologic outcomes of 6 weeks versus 6 months of antiviral treatment with valganciclovir oral solution in infants with symptomatic congenital CMV disease; and to correlate change in whole blood viral load with hearing and neurologic outcomes. Participants will include 104 male and female neonates (less than or equal to 30 days) with symptomatic congenital CMV.

Change in Best Ear Hearing Assessments at 6 Months.
Ramy czasowe: 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.

Zakończenie podstawowe (Rzeczywisty)

Zakończenie podstawowe

Data, w której ostatni uczestnik badania klinicznego został przebadany lub otrzymał interwencję w celu zebrania ostatecznych danych dla głównego pomiaru wyniku. To, czy badanie kliniczne zakończyło się zgodnie z protokołem, czy też zostało zakończone, nie ma wpływu na tę datę. W przypadku badań klinicznych z więcej niż jedną miarą wyniku pierwotnego i różnymi datami zakończenia termin ten odnosi się do daty zakończenia gromadzenia danych dla wszystkich miar wyniku pierwotnego. „Przewidywana” data ukończenia podstawowego badania to data, którą naukowcy uważają za pierwotną datę zakończenia badania.
