Trial summary

Cytomegalovirus (CMV) DNAemia occurs frequently in allogeneic hematopoietic stem cell transplant (allo-HSCT) recipients.Both high-level and persistent virus DNAemia are known risk factors for CMV end-organ disease and perhaps non-relapse mortality. Read more about this study

About this study

Official title: Pre-engraftment Cytomegalovirus DNAemia in Allogeneic Hematopoietic Stem Cell Transplant Recipients: Incidence, Risk Factors and Clinical Outcomes

Cytomegalovirus (CMV) DNAemia occurs frequently in allogeneic hematopoietic stem cell transplant (allo-HSCT) recipients.Both high-level and persistent virus DNAemia are known risk factors for CMV end-organ disease and perhaps non-relapse mortality. CMV DNAemia is usually documented after engraftment, but it may occur before. The virological features and clinical consequences of these latter early-onset episodes remain largely unexplored. The U.S. Food and Drug Administration (FDA) has recently approved letermovir for prophylaxis of CMV infection and disease in adult CMV-seropositive allo-HSCT recipients (PREVYMIS™, Merck \& Co., New Jersey, USA). In accordance with the design of the phase III, double-blind trial the drug may be administered as early as the day of transplant and no later than 28 days post-transplant. Nevertheless, the timing of drug inception should be contingent on the clinical impact of very early episodes of CMV DNAemia. In a recent work from our group (single-center study) we found that a total 38 out of the 197 patients in our series developed CMV DNAemia before engraftment (cumulative incidence (CI), 19%; 95% CI, 10-30.3%). Nine episodes of CMV DNAemia were detected prior to the time of donor progenitor cell infusion. A greater number of post-engraftment episodes required preemptive antiviral therapy compared with pre-engraftment episodes (62.5% vs 44.7%; P=0.05). The cellular content of the donor progenitor cell infusion and transplant characteristics of patients did not differ between patients with pre- or post-engraftment CMV DNAemia. The cumulative incidence of overall mortality by days 100 and 365, aGvHD by day 100 and relapse by day 365 were not significantly different between patients with pre-engraftment or post-engraftment CMV DNAemia. Our study was limited by the retrospective and single-center design and the scarce number of pre-engraftment CMV DNAemia episodes included; therefore, the results may not be extrapolated to other transplantation centers or patient cohorts. Further retrospective and prospective studies are thus required to validate the data presented herein.

Read the detailed description

Episodes of CMV DNAemia developing prior to engraftment (pre-CMV DNAemia), which usually occur between the third and fourth week after allo-HSCT, may conceivably have a different course from episodes emerging after engraftment once patients have begun to expand donor-derived T cells (post-CMV DNAemia). Thus, whether the precise timing of Letermovir treatment initiation should matter will ultimately depend on the impact of CMV DNAemia episodes developing prior to engraftment on clinical outcomes. There is limited information available on this topic. Here, we conducted a retrospective multicenter, non-interventional study to further address this issue.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time to Engraftment (Days) Stratified by CMV DNaemia Occurring Before or After Neutrophil's Engraftment

    absolute neutrophil count ≥500/mm3 on 3 consecutive days,, the first of which being time of engraftment.

    Measured: 30 days

Secondary outcomes (2)
  1. Overall Mortality

    total number of deaths from any cause

    Measured: 1 year

  2. Non-relapse Mortality

    total number of deaths without relapse or underlying disease progression

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of CMV DNAemia Pre-engraftment, run by Fundación para la Investigación del Hospital Clínico de Valencia at 1 site in Spain.

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 4 inclusion and 3 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 11 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. 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?

Yes. Results are posted in the registry (first posted 11 Dec 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Time to Engraftment (Days) Stratified by CMV DNaemia Occurring Before or After Neutrophil's Engraftment (time frame: 30 days). 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 11 Dec 2020.
