Trial Summary

What is the purpose of this trial?

This randomized phase II trial studies how well vaccine therapy works in reducing the frequency of cytomegalovirus severe infections (events) in patients with hematologic malignancies undergoing donor stem cell transplant. Vaccines made from a peptide may help the body build an effective immune response and may reduce cytomegalovirus events after donor stem cell transplant.

Eligibility Criteria

This trial is for patients with blood cancers like lymphoma, leukemia, and myelodysplastic syndrome who are undergoing stem cell transplants. They must understand the study, agree to follow-up procedures for a year post-transplant, be HLA A*0201 positive, CMV seropositive, not pregnant or breastfeeding, willing to use contraception and have no recent experimental anti-CMV treatments.

Inclusion Criteria

My leukemia is in an early or slightly advanced stage.
Participant must be willing to comply with study and/or follow-up procedures, including willingness to be followed for one year post-HCT
My leukemia is in the first or second remission without worsening, despite some lymph node swelling.

Exclusion Criteria

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
You have not previously participated in a study involving an experimental CMV vaccine.
I will be taking specific medications from my transplant until day 70 after.

Treatment Details

Interventions

  • CMVpp65-A*0201 peptide vaccine
Trial Overview The trial tests if a vaccine made from a peptide can reduce severe cytomegalovirus infections in patients after donor stem cell transplant. It's randomized: some get the actual vaccine while others receive a placebo. The goal is to see how well the immune system responds.
