CMV-MVA Triplex Vaccination in HLA-Matched Related Stem Cell Donors for the Prevention of CMV Infection in Patients Undergoing Hematopoietic Stem Cell Transplant

United States216 participantsStarted 2024-07-12

Plain-language summary

This phase II clinical trial tests how well the cytomegalovirus-modified vaccinica Ankara (CMV-MVA) Triplex vaccine given to human leukocyte antigens (HLA) matched related stem cell donors works to prevent cytomegalovirus (CMV) infection in patients undergoing hematopoietic stem cell transplant. The CMV-MVA Triplex vaccine works by causing an immune response in the donors body to the CMV virus, creating immunity to it. The donor then passes that immunity on to the patient upon receiving the stem cell transplant. Giving the CMV-MVA triplex vaccine to donors may help prevent CMV infection of patients undergoing stem cell transplantation.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Time from transplantation to cytomegalovirus (CMV) disease or pre-emptive treatment following CMV reactivation (efficacy)

Timeframe: From hematopoietic stem cell transplantation (HCT) to day 180

Timeframe: Up to day 100 post HCT

Incidence of severe acute graft versus host disease (aGHVD) (safety in HCT-recipients)

Timeframe: Up to 100 days post HCT

Incidence of severe adverse events (AEs) (safety in HCT-recipients)

Timeframe: Within 2 weeks from transplantation and up to 1 year post HCT

Incidence of grade 3 and higher AEs (safety in HCT-donors)

Timeframe: Within 14 days
