Cytomegaloviral Infection Hematopoietic Cell Transplant Recipient

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This phase I/II trial studies the side effects and best dose of multi-antigen cytomegalovirus (CMV)-modified vaccinia ankara vaccine and to see how well it works in treating pediatric patients with positive cytomegalovirus who are undergoing donor stem cell transplant. Multi-antigen CMV-modified vaccinia ankara vaccine may help people resist CMV life-threatening complications.

Inclusion Criteria	Exclusion Criteria
* All subjects (or their guardians) must have the ability to understand and the willingness to sign a written informed consent; age appropriate assent will be obtained per institutional guidelines; to allow non-English patients to participate in this study, bilingual health services will be provided in the appropriate language when feasible * Participant must be willing to comply with study and/or follow-up procedures, including willingness to be followed for one year post-HCT * Planned allogenic (allo)-HCT, with 9/10 or 10/10 (A, B, C, DRB1, DQB1) high/intermediate resolution HLA donor allele matching and with no T-cell depletion of graft * Planned related HCT with molecular 3/6 HLA donor allele matching (haploidentical) (for phase I only) * CMV seropositive at the time of HCT * Conditioning and immunosuppressive regimens according to institutional guidelines are permitted * Negative serum or urine beta-human chorionic gonadotropin (HCG) test (female patient of childbearing potential only) within two weeks of registration * Seronegative for human immunodeficiency virus (HIV), hepatitis C virus (HCV); if hepatitis B virus (HBV) core seropositive, absence of HBV deoxyribonucleic acid (DNA) within 2 months of registration * Agreement by females of childbearing potential and sexually active males to use an effective method of contraception (hormonal or barrier method of birth control or abstinence) prior to study entry and for up to 90 days post-HCT; should a woman become pregnant or suspect that she is pregnant while participating on the trial, she should inform her treating physician immediately	* TRANSPLANT RELATED CRITERIA: Patients undergoing cord blood transplant (CB-HCT) * Any prior investigational CMV vaccine * Anti-CMV therapy in the last 6 months * Live attenuated vaccines * Medically indicated subunit (Engerix-B for HBV; Gardasil for human papillomavirus \[HPV\]) or killed vaccine (e.g. influenza, pneumococcal) * Allergy treatment with antigens injections * Alemtuzumab, cyclophosphamide, ATG or any equivalent in vivo T-cell depleting agent; Note: Pre-transplant ATG is permitted * Antiviral medications with known therapeutic effects on CMV such as ganciclovir (GCV)/valine (VAL), FOS, Cidofovir, CMX-001, maribavir; acyclovir has no known therapeutic efficacy against CMV and is allowable as standard of care to prevent herpes simplex virus (HSV) * Prophylactic therapy with CMV immunoglobulin or prophylactic antiviral CMV treatment; intravenous immunoglobulin therapy (IVIG) is allowed * Other investigational product-concurrent enrollment in other clinical trials using any investigational new drug (IND) drugs with unknown effects on CMV or with unknown toxicity profiles is prohibited * Other medications that might interfere with the evaluation of the investigational product * Patients with congenital immune deficiency * Patients with active autoimmune conditions requiring systemic immunosuppressive therapy within the previous 5 years are not eligible, the exception to this is patients with aplastic anemia, who are eligible * Pregnant women and women who are lactating; CMV-MVA Triplex risks to pregnant women are unknown; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with the administered vaccine, also breastfeeding should be discontinued if the mother is enrolled on this study * Any other condition that would, in the investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures, e.g., social/psychological issues, etc * Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issue related to feasibility/logistics)

Inclusion Criteria

Exclusion Criteria

* All subjects (or their guardians) must have the ability to understand and the willingness to sign a written informed consent; age appropriate assent will be obtained per institutional guidelines; to allow non-English patients to participate in this study, bilingual health services will be provided in the appropriate language when feasible
* Participant must be willing to comply with study and/or follow-up procedures, including willingness to be followed for one year post-HCT
* Planned allogenic (allo)-HCT, with 9/10 or 10/10 (A, B, C, DRB1, DQB1) high/intermediate resolution HLA donor allele matching and with no T-cell depletion of graft
* Planned related HCT with molecular 3/6 HLA donor allele matching (haploidentical) (for phase I only)
* CMV seropositive at the time of HCT
* Conditioning and immunosuppressive regimens according to institutional guidelines are permitted
* Negative serum or urine beta-human chorionic gonadotropin (HCG) test (female patient of childbearing potential only) within two weeks of registration
* Seronegative for human immunodeficiency virus (HIV), hepatitis C virus (HCV); if hepatitis B virus (HBV) core seropositive, absence of HBV deoxyribonucleic acid (DNA) within 2 months of registration
* Agreement by females of childbearing potential and sexually active males to use an effective method of contraception (hormonal or barrier method of birth control or abstinence) prior to study entry and for up to 90 days post-HCT; should a woman become pregnant or suspect that she is pregnant while participating on the trial, she should inform her treating physician immediately

* TRANSPLANT RELATED CRITERIA: Patients undergoing cord blood transplant (CB-HCT)
* Any prior investigational CMV vaccine
* Anti-CMV therapy in the last 6 months
* Live attenuated vaccines
* Medically indicated subunit (Engerix-B for HBV; Gardasil for human papillomavirus \[HPV\]) or killed vaccine (e.g. influenza, pneumococcal)
* Allergy treatment with antigens injections
* Alemtuzumab, cyclophosphamide, ATG or any equivalent in vivo T-cell depleting agent; Note: Pre-transplant ATG is permitted
* Antiviral medications with known therapeutic effects on CMV such as ganciclovir (GCV)/valine (VAL), FOS, Cidofovir, CMX-001, maribavir; acyclovir has no known therapeutic efficacy against CMV and is allowable as standard of care to prevent herpes simplex virus (HSV)
* Prophylactic therapy with CMV immunoglobulin or prophylactic antiviral CMV treatment; intravenous immunoglobulin therapy (IVIG) is allowed
* Other investigational product-concurrent enrollment in other clinical trials using any investigational new drug (IND) drugs with unknown effects on CMV or with unknown toxicity profiles is prohibited
* Other medications that might interfere with the evaluation of the investigational product
* Patients with congenital immune deficiency
* Patients with active autoimmune conditions requiring systemic immunosuppressive therapy within the previous 5 years are not eligible, the exception to this is patients with aplastic anemia, who are eligible
* Pregnant women and women who are lactating; CMV-MVA Triplex risks to pregnant women are unknown; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with the administered vaccine, also breastfeeding should be discontinued if the mother is enrolled on this study
* Any other condition that would, in the investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures, e.g., social/psychological issues, etc
* Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issue related to feasibility/logistics)
