Vaccine Therapy in Reducing the Frequency of Cytomegalovirus Events in Patients With Hematologic Malignancies Undergoing Donor Stem Cell Transplant

Korábbi kezelés

• Any prior investigational CMV vaccine
• Experimental anti-CMV chemotherapy in the last 6 months
• Planned medications from the time of HCT to day 70 post-HCT:
  • Live attenuated vaccines
  • Medically indicated subunit (Engerix-B for HBV; Gardasil for human papilloma virus [HPV]) or killed vaccines (e.g. influenza, pneumococcal, or allergy treatment with antigen injections)
  • Allergy treatment with antigens injections
  • Alemtuzumab or any equivalent in vivo T-cell depleting agent; this includes anti-thymocyte globulin (ATG) and post-transplant cyclophosphamide
  • Antiviral medications with known therapeutic effects against CMV such as ganciclovir (GCV)/valine (VAL), foscarnet (FOS), cidofovir, hexadecyloxypropyl-cidofovir (CMX-001) and maribavir; acyclovir has no therapeutic efficacy against CMV and is allowable as standard of care to prevent herpes simplex virus (HSV)
  • Other investigational product - concurrent enrollment in other clinical trials using an investigational product is prohibited
  • Other medications that might interfere with the evaluation of the investigational product
• Patients with active autoimmune conditions requiring systemic immunosuppressive therapy within the previous 5 years are not eligible

Más betegség

• 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

Egyéb

• Pregnant women and women who are lactating; breastfeeding should be discontinued if the mother is enrolled on this study
• 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)

• All subjects must have the ability to understand and the willingness to sign a written informed consent
• Participant must be willing to comply with study and/or follow-up procedures, including willingness to be followed for one year post-HCT
• 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 (for acute lymphoblastic leukemia/lymphoblastic lymphoma, the disease status needs to be in hematologic remission by bone marrow and peripheral blood; persistent lymphadenopathy on computed tomography [CT] or CT/positron emission tomography [PET] scan without progression is allowed)
  • Acute myeloid leukemia in first or second remission
  • Chronic myelogenous leukemia in first chronic or accelerated phase, or in second chronic phase
  • Other hematologic malignancies including chronic lymphocytic leukemia, myeloproliferative disorders and myelofibrosis; patients with multiple myeloma and those with non-malignant disease such as aplastic anemia are excluded
• HLA A*0201 High resolution, 4-digit typing is required at HLA-A2 to ensure A*0201 status.
• CMV seropositive (recipient)
• Planned related or unrelated HCT, with HLA donor allele matching; related donor must be an 8/8 match for HLA-A, -B, and -C at intermediate (or higher) resolution, and -DRB1 at high resolution using deoxyribonucleic acid (DNA)-based typing; unrelated donor must be an 8/8 match at HLA-A, -B, -C, and -DRB1 at high resolution using DNA-based typing; patients undergoing a second allo HCT are not eligible (patients who have undergone a previous autologous HCT are eligible)
• Planned HCT with no ex-vivo T cell depletion of graft; 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) and active hepatitis B virus (HBV) (surface antigen negative) 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
