- Women of child-bearing potential and men must agree to use adequate contraception
(hormonal or barrier method of birth control or abstinence) prior to study entry and
for six months following duration of study participation; should a woman become
pregnant or suspect that she is pregnant while participating on the trial, she should
inform her treating physician immediately
- All medications, supportive care, blood products or radiation therapy taken or
administered during the trial will be documented in the subject's clinical/hospital
and case report form (CRF), using City of Hope (COH) guidelines; the subject's
clinical information will be recorded on the appropriate CRF
- Concurrent enrollment in other clinical trials using an investigational product is
prohibited
- The use of alemtuzumab for immunosuppression is not permitted in this study
- Prophylactic therapy with CMV immunoglobulin or prophylactic antiviral CMV treatment
is not allowed
- Medications that might interfere with the evaluation of the investigational product
should not be administered, from 30 days prior to participation on the trial and up to
14 days after the second vaccination (day 70 post-HCT); medications in this category
include, but are not limited to:
- Live attenuated vaccines
- Medically indicated subunit (Engerix-B for HBV; Gardasil for HPV) or killed
vaccines (e.g. influenza, pneumococcal, or allergy treatment with antigen
injections)
- Antiviral treatment for herpes simplex virus (HSV), human herpes virus 6 (HHV6),
Epstein-Barr virus (EBV) and adenovirus including the use of GVC/VAL, FOS, Cidofovir,
CMX-001 may also suppress reactivation of CMV, thus it will not be allowed in this
study; patients requiring such treatment before randomization (day 28) will be removed
from the study and replaced; reasons for removal will be reported in the patient's CRF
- All enrolled recipients who will require anti-CMV therapy before day 28 will be
replaced, treated and monitored as required by COH standard of care; GVC/VAL, FOS,
Cidofovir, CMX-001 may be used according to COH standard of care (SOC) for preemptive
management of CMV viremia; should antiviral treatment be required after day 28, the
planned 2nd vaccine injection at day 56 will not be administered (vaccine arm only)
- All subjects must have the ability to understand and the willingness to sign a written
informed consent
Exclusion Criteria:

agent
- In vitro T cell depleted graft

from 30 days prior to participation in the trial and up to 14 days after the
second vaccination (day 70 post-HCT)

(vaccine and observation arms) will be reviewed for eligibility and ruled ineligible
to initiate or continue in the study and receive vaccination (for the vaccine arm) if:
- Diagnosed with > grade 2 graft-versus-host disease (GVHD) before day 28 post-HCT,
and diagnosed with > grade 2 GVHD between day 28 post-HCT and administration of
the 2nd vaccine at day 56
