Non Hodgkin Lymphoma Clinical Trial
CMV-MVA Triplex Vaccination of Stem Cell Donors in Preventing CMV Viremia in Participants With Blood Cancer Undergoing Donor Stem Cell Transplant
This phase II trial studies how well multi-peptide CMV-modified vaccinia Ankara (CMV-MVA Triplex) vaccination of stem cell donors works in preventing cytomegalovirus (CMV) viremia in participants with blood cancer undergoing donor stem cell transplant. Giving a vaccine to the donors may boost the recipient's immunity to this virus and reduce the chance of CMV disease after transplant.
I. Establish the feasibility and safety of priming CMV immunity in donors by Triplex vaccination prior to peripheral blood stem cell (PBSC) harvest.
I. Examine if Triplex vaccination of hematopoietic stem cell transplant (HCT) donors has an impact on CMV events.
Donors receive multi-peptide CMV-modified vaccinia Ankara vaccine injection between days -60 and -10 prior to granulocyte colony stimulating factor mobilization. Participants undergo hematopoietic cell transplantation on day 0.
After completion of study treatment, participants are followed up for 1 year.
DONOR: Ability to comprehend the investigational nature of the study and provide informed consent
DONOR: Willing to receive Triplex vaccination, a minimum of 14 days prior to the PBSC collection
DONOR VACCINATION: Donors are eligible to be vaccinated prior to the determination of their human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) and human T-cell lymphotropic virus (HTLV) status. The exclusion criteria for transplant is independent of eligibility for vaccination and is determined by the exclusion criteria for transplant from donors
RECIPIENT: All subjects must have the ability to understand and the willingness to sign a written informed consent
RECIPIENT: Participant must be willing to comply with study and/or follow-up procedures, including willingness to be followed for one year post-HCT
RECIPIENT: Age 18 to 75 years
RECIPIENT: Planned HCT for the treatment of the following hematologic malignancies: lymphoma (Hodgkin and non-Hodgkin), myelodysplastic syndrome, acute lymphoblastic leukemia in first or second remission, acute myeloid leukemia in first or second remission, chronic myelogenous leukemia (in first chronic or accelerated phase, or in second chronic phase), chronic lymphocytic leukemia, myeloproliferative disorders and myelofibrosis (City of Hope [COH] only). Patients with multiple myeloma are excluded
RECIPIENT: CMV seropositive
RECIPIENT: Planned related HCT with 8/8 (A, B, C, DRB1) high resolution HLA donor allele matching
RECIPIENT: Conditioning and immunosuppressive regimens according to institutional guidelines are permitted
RECIPIENT: Negative serum or urine beta-human chorionic gonadotropin (HCG) test (female patient of childbearing potential only) within two weeks of registration
RECIPIENT: Seronegative for HIV, HCV and active HBV (surface antigen negative) within 2 months of registration
RECIPIENT: Agreement by females of childbearing potential and males with partners of childbearing potential to use effective contraception (hormonal or barrier method 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 FROM DONOR: Unfit to undergo standard stem cell mobilization and apheresis e.g. abnormal blood counts, history of stroke, uncontrolled hypertension
TRANSPLANT FROM DONOR: Sickling hemoglobinopathy including HbSS, HbAS, HbSC
TRANSPLANT FROM DONOR: Positive for human immunodeficiency virus (HIV), active hepatitis B (hepatitis B virus [HBV]), hepatitis C (hepatitis C virus [HCV]) or human T-cell lymphotropic virus (HTLV-I/II). This holds true even if donors have been already vaccinated according to criteria for donor vaccination
TRANSPLANT FROM DONOR: Donors with impaired cardiac function are excluded. Electrocardiography is routine for potential HCT donors over 60 years old and those with a history of heart disease. Subjects in whom cardiac function is abnormal (excluding 1st degree branch block, sinus brachycardia, sinus tachycardia or non-specific T wave changes) are ineligible for Triplex vaccination
TRANSPLANT FROM DONOR: Severe psychiatric illness. Mental deficiency sufficiently severe as to make compliance with the donation procedure unlikely, and making informed consent impossible
RECIPIENT: Any prior investigational CMV vaccine
RECIPIENT: Experimental anti-CMV chemotherapy in the last 6 months
RECIPIENT: Planned medications from the time of HCT to day 70 post-HCT
RECIPIENT: Live attenuated vaccines
RECIPIENT: Medically indicated subunit (Engerix-B for HBV; Gardasil for human papillomavirus [HPV]) or killed vaccines (e.g. influenza, pneumococcal, or allergy treatment with antigen injections)
RECIPIENT: Allergy treatment with antigens injections
RECIPIENT: Alemtuzumab or any equivalent in vivo T-cell depleting agent
RECIPIENT: Antiviral medications with known therapeutic effects on CMV such as ganciclovir (GCV)/valganciclovir (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)
RECIPIENT: Prophylactic therapy with CMV immunoglobulin or prophylactic antiviral CMV treatment (Letermovir is permitted). EXCEPT for low risk patients [8/8 high resolution HLA donor allele matching HCT])
RECIPIENT: 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
RECIPIENT: Other medications that might interfere with the evaluation of the investigational product
RECIPIENT: Diagnosis with autoimmune disease
RECIPIENT: Pregnant women and women who are lactating. The risks of CMV-MVA-Triplex 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. Breastfeeding should be discontinued if the mother is enrolled on this study
RECIPIENT: 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
RECIPIENT: Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)
