Conditions

Lymphoma, Multiple Myeloma

Brief summary

This is a prospective, interventional study administering 2 doses of the experimental vaccine (CMV-MVA Triplex) to 20 evaluable patients (10 CMV-seropositive and 10 seronegative) undergoing autologous hematopoietic cell transplantation (HCT) for lymphoma or myeloma on days 28 and 56 post-HCT. The absolute number of adaptive NK cells (CD56dimCD57+NKG2C+) at various days will be compared.

Inclusion criteria

* Age \> 18 years * Lymphoma or multiple myeloma * Planned co-enrollment on current (at the time of this study version) or future (opening subsequent to this study) standard of care autologous stem cell transplant protocol. \* Must meet all eligibility requirements of the co-enrolled parent study * Sexually active females of childbearing potential and males with partners of child-bearing potential must agree to use adequate birth control until at least day 100 post-HCT * Voluntary written consent signed before performance of any study-related procedure not part of normal medical care

Exclusion criteria

* CMV immunoglobulin, valganciclovir, ganciclovir, foscarnet, or other anti-CMV therapy within 3 months before the first vaccine is planned. Acyclovir and valacyclovir are allowed. * Pregnant or breast feeding. The FDA has not classified this agent into a specified pregnancy category. Females of childbearing potential must have a blood test or urine study within 14 days prior to registration to rule out pregnancy * Planned immunotherapy post-HCT. Proteasome inhibitors and/or immunomodulators, such as but not limited to Lenalidomide or Pomalidomide, used for myeloma maintenance are allowed.
