chemotherapy).
7. Female subject must be either:
* Of non-child bearing potential:
o post-menopausal (defined as at least 1 year without any menses)
prior to Screening and if < 50 years of age and not documented to be surgically sterile must have a negative urine or serum pregnancy test at screening, or
o documented surgically sterile or status post hysterectomy (at least 1 month prior to Screening).
Or, if of childbearing potential:
o must have a negative urine or serum pregnancy test at Screening,
and
o if heterosexually active, must use at least one form of birth control*
(which must be a barrier method) starting at Scre
1. Subject has active CMV disease or infection or has received treatment for active CMV disease or infection within 3 months (90 days) prior to transplant.
2. Subject has planned CMV prophylactic therapy with antiviral drugs or CMV-specific immunoglobulins from randomization through the primary study period completion/Day 365 Visit (V 14).

a. Alemtuzumab within 60 days prior to transplant, including conditioning regimen. Subjects for
whom treatment with alemtuzumab is planned at any time from 60 days prior to through one
year post-transplant should not be enrolled in the trial.
b. T cell depletion of donor cell product.
c. Administration of a CMV vaccine, including any prior exposure to ASP0113.
7. Subject has received an allogeneic stem cell transplant within one year prior to transplant (subjects who have received a prior autologous transplant are allowed).
8. Subject has a current malignancy in addition to the malignancy being treated for the study or the subject has a history of any other malignancy (within the past 5 years prior to Screening) except non-metastatic basal or squamous cell carcinoma of the skin that has been treated successfully or cancer in situ of the cervix uteri that has been handled by local surgery.
