Patients with moderate or severe CMV disease less than 21 days old who have a maternal donor who has a CMV response to the peptivators will be screened. All patients will receive treatment with valganciclovir or ganciclovir. There is a safety run in with treatment with CMV CTLs in cohort 1 and if found to be safe, will proceed to cohort 2 for randomization to receive antiviral therapy with or without CMV CTLs.

Given the vulnerability and poor outcomes of preterm neonates and neonates in general to viral infection, including the need for prolonged antiviral therapy for 6 or more months to achieve just modest improvements in sensorineural functions, CMV CTL therapy offers a promising alternative. CMV CTL treatment will build on the hosts innate immune capacity to create a more effective and permanent defense against collateral injury arising from CMV infections. Patients who meet all inclusion/exclusion criteria with a maternal donor who meet all donor criteria will be enrolled onto study. Cohort 1 is a safety run-in; the first 3 patients enrolled will be treated with anti-viral and CMV CTLs. The external DSMB will review the data from the first patient, and if there are no adverse events or dose-limiting toxicities observed, approve patient 2, and then 3, 28 days after the prior patients last CTL infusion. Assuming there are no adverse events in any of the first 3 patients, the study will proceed to Cohort 2. Cohort 2 will be randomized 1:1 to either anti-viral treatment alone or anti-viral treatment plus CMV CTLs. Patients who are randomized to receive CMV CTLs will get their first infusion on Day 0. If the patient fails to achieve a CR, they may receive one infusion every 2 weeks up to 5 maximum CMV CTL infusions as long as there are no DLTs or AEs observed

Patients will receive maternal CMV CTLs on day 0. Additional doses of CMV CTLs may be re-infused at a minimum of every two weeks for a maximum of five total infusions (maximum 2.5 x 104 CD3/kg) only in patients not achieving a CR and no prior dose limiting toxicity of any prior dose.
All patients will receive anti-viral therapy with one of the following: 4.2.2 Valganciclovir Dosing: 16 mg/kg/dose PO q12h OR 4.2.3 Ganciclovir Dosing: 6 mg/kg/dose IV q12h Dose adjustments: * Reduce dose by 50% for ANC less than 500 cells/mm3 * Hold the dose if ≤ 200 cells/mm3 until recovery ≥ 500 cells/mm3 * Treatment will continue for 6 months

RECRUITINGTo determine the safety of giving CMV CTLs combined with anti-viral therapy in neonates with CMV
the incidence and severity of Grade I-IV acute GVHD within 8 weeks that is probably or directly related to CMV-CTL infusion after last CMV CTL infusion will be evaluated to determine the safety profile of CMV CTLs in neonates
Time frame: 12 weeks
To determine response rates to treatment with CMV CTLS and anti-viral medication
response rates will be measured by monitoring CMV PCR levels. A complete response to CMV-CTLs will be those with undetectable viral load by qRT-PCR
Time frame: 12 weeks
