Brief summary
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.
Detailed description
PRIMARY OBJECTIVES: I. Establish the feasibility and safety of priming CMV immunity in donors by Triplex vaccination prior to peripheral blood stem cell (PBSC) harvest. SECONDARY OBJECTIVES: I. Examine if Triplex vaccination of hematopoietic stem cell transplant (HCT) donors has an impact on CMV events. OUTLINE: 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.

Eligibility
Inclusion criteria
* 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
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Delayed Engraftment | Up to 1 year from stem cell infusion. | Time to neutrophil engraftment was defined as days from stem cell infusion to the first of three consecutive days of absolute neutrophil count ≥0.5 x 109/L. Delayed engraftment was defined as ≥20 days to neutrophil recovery. |
| Severe (Grade III-IV) Acute Graft Versus Host Disease | Up to 6 months from stem cell infusion | Acute graft versus host disease (aGvHD) happens within days or as late as 6 months after allogeneic transplants. The three main tissues that acute GVHD affects are the skin, liver, and gastrointestinal tract. |
| Number of Recipients With Grade 3-4 Adverse Events | Up to 1 year from stem cell infusion. | Toxicities were assessed in recipients by Common Terminology Criteria for Adverse Events version 4.0. |
| Number of Donors With Grade 2-3 Adverse Events | Up to 6 months after G-CSF mobilization | Toxicities were assessed in recipients by Common Terminology Criteria for Adverse Events version 4.0. |
| 100-Day Non-Relapse Mortality (NRM) | From stem cell infusion up to 100 days post-HSCT (hematopoietic stem cell transplantation). | NRM was defined as death without recurrent or progressive disease after allogeneic transplant. Probabilities of NRM were estimated with the use of cumulative incidence curves, with relapse viewed as a competing risk. |
