About this study

Official title: A Multi-country, Multi-center, Retrospective Chart Review to Describe the Use of Maribavir and Its Effectiveness in Patients With Post-Transplant Cytomegalovirus Infection/Disease

The main aim of this study is to check how effective the treatment with Maribavir has been to remove the CMV viruses from the blood of an adult person with CMV infection after a transplant. Other aims are to learn more about how maribavir is used in normal clinical routine, study the profiles of adults treated with maribavir, and what other treatments have been given, and describe healthcare resources used for CMV management.

Only data already available in the medical records of the participants will be reviewed and collected during this study.

Read the detailed description

This study will include two main periods of retrospective data collection from medical charts: the pre-index period and the post-index period. The index date is defined as the date of initiation of maribavir dosing, as documented in the medical records. The pre-index period covers the time from the transplant date to the index event, while the post-index period starts at the index event and ends at the date of chart abstraction, death, or loss to follow-up, whichever comes first.

    This is a non-interventional study.

Study groups in NCT06615921
Study groupRoleWhat they receive
Participants With CMV Infection RefractoryParticipants who had a CMV infection/disease that is refractory to treatment (with or without resistance). Data will be retrospectively collected from date of solid organ transplant (SOT) or hematopoietic stem cell transplant (HSCT) up to the start date of chart abstraction, death or loss to follow-up, whichever comes first. Participants will be considered as refractory if they show no change or increased viremia after at least 2 weeks of appropriately dosed antiviral therapy.

Participants With CMV Infection IntolerantParticipants with CMV infection intolerant to anti-CMV treatment. Data will be retrospectively collected from date of SOT/HSCT up to the start date of chart abstraction, death or loss to follow-up, whichever comes first. Intolerant participants identified based on physician judgment.
Receives: Other: No Intervention

Questions about this trial

What is this clinical trial studying?

An observational study of Cytomegalovirus (CMV), run by Takeda at 45 sites in 10 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 45 sites in Germany, France, United Kingdom, Spain, Netherlands and 5 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Viremia Clearance Before the End of Maribavir Treatment (time frame: From transplantation date until start of chart abstraction or date of death from any cause, whichever comes first, up to approximately 32 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Aug 2025.
