Child Bearing Potential:
The effects of Tet-CMV + PF03512676 on the developing fetus are unknown; however,
PF03512676 had been determined to be embryolethal in rabbits and teratogenic in developing
rats and rabbits; for this reason, 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
Protocol-Specific Criteria:
- 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 other
than chemotherapy, radiation therapy, or conditioning regimens is prohibited
- The use of alemtuzumab for immunosuppression is not permitted in this study
- Prophylactic therapy with CMV immunoglobulin or prophylactic antiviral treatment is
not allowed
- Medications that might interfere with the evaluation of the investigational product
should not be administered unless absolutely necessary, from 30 days prior to the
trial initiation up to 6 months afterwards; medications in this category include, but
are not limited to:
- Liver attenuated vaccines
- Medically indicated subunit 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, acyclovir,
CMX-001 may also suppress reactivation of CMV, thus it will not be allowed in this
study; patients requiring such treatment will be removed from the study and replaced;
reason for removal will be reported in the patient's CRF
- All enrolled recipients who will require anti-CMV therapy before day 100 will be
treated and monitored as required by COH standard of care; GVC/VAL, FOS may be used
according to COH standard of care (SOC) for preemptive management of CMV viremia;
should antiviral treatment be required between day 29 and 56, 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:
- A poor-risk patient, as defined by any of the following:
- Chronic myelogenous leukemia in blast crisis
- Acute myeloid leukemia beyond second remission
- Multiple myeloma
- Aplastic anemia
- Planned immunosuppression with alemtuzumab or any equivalent in vivo T-cell depleting
agent
- In vitro T cell depleted graft
- Planned prophylactic therapy with CMV immunoglobulin
- Planned CMV prophylactic therapy
- Experimental anti-CMV chemotherapy in the last 6 months
- Diagnosed with autoimmune disease
- Receipt of the following substances:
- Any prior investigational CMV vaccine
- Live attenuated vaccines, medically indicated subunit or killed vaccines from 30
days prior to participation in the trial and up to 14 days after the second
vaccination (day 70 post-HCT)
- Investigational research products or allergy treatment with antigens injections
from 30 days prior to participation in the trial and up to 14 days after the
second vaccination (day 70 post-HCT)
- Pregnant and/or breast feeding if a female recipient
- Refusing to use contraception up to 90 days post-HCT
POST-HCT STUDY-SPECIFIC EXCLUSIONS:
On days 28 post-HCT (immunization day for the vaccine arm) all study recipients 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)
- Receiving corticosteroid therapy > 1 mg/kg/day
- Had relapse
- Experience graft failure (absolute neutrophil count < 500/mm^3)
- Receiving antiviral treatment with GVC/VAL, FOS, acyclovir, CMX-001
- Ongoing non-hematological post-HCT toxicities > grade 2 on the Common Terminology
Criteria for Adverse Events (CTCAE) scale
