About
This randomized phase I trial studies the side effects of vaccine therapy in preventing cytomegalovirus (CMV) infection in patients with hematological malignancies undergoing donor stem cell transplant. Vaccines made from a tetanus-CMV peptide or antigen may help the body build an effective immune response and prevent or delay the recurrence of CMV infection in patients undergoing donor stem cell transplant for hematological malignancies.
Full description
PRIMARY OBJECTIVES: I. To discover whether two administrations of 2.5 mg tetanus (Tet)-CMV peptide co-injected with 1 mg of PF-03512676 (tetanus-CMV fusion peptide vaccine), by subcutaneous (SC) route on days 28 and 56 post-hematopoietic cell transplantation (HCT) are safe and well tolerated in human leukocyte antigen (HLA) A*0201 CMV-positive recipients of allogeneic HCT.
SECONDARY OBJECTIVES:
I. To measure levels of CMV-specific T cells in vaccinated compared to unvaccinated HCT recipients (control arm).
II. To assess whether vaccination of HCT recipients with Tet-CMV co-injected with PF03512676 reduces expression of programmed death 1 (PD-1) on CMV-specific T cells.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive Tet-CMV + PF03512675 SC on days 28 and 56 post-HCT.
ARM II: Patients undergo immune monitoring only.
After completion of study treatment, patients are followed up at days 70, 84, 100, 130, 160, and 180.

-
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)
