Cytomegalovirus (CMV) Vaccine in Donors and Recipients Undergoing Allogeneic Hematopoietic Cell Transplant (HCT)

October 17, 2024 updated by: Astellas Pharma Inc

A Phase 2 Clinical Trial to Evaluate the Safety, Immunogenicity, and Clinical Benefit of a CMV Immunotherapeutic Vaccine in Donors and CMV-Seropositive Recipients Undergoing Allogeneic, Matched Hematopoietic Cell Transplant (HCT)

The purpose of this trial is to evaluate a CMV vaccine given to related donor/recipient pairs (donors prior to peripheral blood stem cell donation and CMV-seropositive recipients just before and after transplantation) and CMV-seropositive recipient-only subjects (related or unrelated) to determine incidence rates of CMV infection, disease, and other complications from immunosuppression and/or transplantation. The outcomes for the groups receiving CMV vaccine will be compared to the outcomes for the group that received the placebo vaccine to see if there is a clinical benefit. For this trial, donors and recipients must have matched HLA genotype (matched at 5/6 or 6/6 HLA loci).

Detailed Description

This study was run by Vical and the record was transferred to Astellas on 1/8/2013.

Trial will enroll up to 240 subjects (160 recipients and 80 donors). Qualified donors and/or CMV-seropositive recipients (donor/recipient pairs or recipient-only subjects) will be assigned randomly to receive either a CMV vaccine or a placebo vaccine. Donors will receive 3 vaccines prior to donation and recipients will receive 1 vaccine pretransplant and up to three vaccines posttransplant. Recipients will be followed for up to 1 year after transplant to evaluate the safety of the vaccine and to see if there is a clinical benefit in the group that received the CMV vaccine. The incidence rates of CMV infection, disease, and other complications from immunosuppression and/or transplantation will be studied.

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

Access to anonymized individual participant level data collected during the study, in addition to study-related supporting documentation, is planned for studies conducted with approved product indications and formulations, as well as products terminated during development. Studies conducted with product indications or formulations that remain active in development are assessed after study completion to determine if Individual Participant Data can be shared. Further details on Astellas' data sharing policy can be found at https://www.clinicaltrials.astellas.com/transparency/.

IPD Sharing Time Frame

Access to participant level data is offered to researchers after publication of the primary manuscript (if applicable) and is available as long as Astellas has legal authority to provide the data.

IPD Sharing Access Criteria

Researchers must submit a proposal to conduct a scientifically relevant analysis of the study data. The research proposal is reviewed by an Independent Research Panel. If the proposal is approved, access to the study data is provided in a secure data sharing environment after receipt of a signed Data Sharing Agreement.
