Study summary

This is a single-center, non-interventional, retrospective study of data, at the level of the individual without identification, extracted from medical records of adult patients undergoing a kidney transplant procedure after 1st from January 2018 until reaching the sample size enrollment (around 500 individuals); this refers to the period of verification of individuals' eligibility for entry into the study. Individuals under strategy preemptive patients who developed CMV infection/disease within 12 months after transplantation. The data will be collected from date of transplant (including pre-transplant clinical history) until completion of at least 12 months after transplantation, or until graft loss, or recipient death or loss to follow-up, when/if applicable.

Read the detailed description

Data will be collected from medical records and will include transplant recipient characteristics, transplant-related information, CMV status, clinical outcomes, treatment patterns, healthcare resource utilization and captured on an electronic Intake Form.

Study-specific Case Report (eCRF) The sponsor will create a Statistical Analysis Plan (SAP) before collection begins of data. The eCRF system will comply with research regulations

Study population

The study population will be entirely adult kidney transplant recipients (age ≥18 years at the time of time of transplantation) who developed a first episode of CMV infection/disease in the first year of transplant. Eligible individuals will be enrolled consecutively based on transplant date, starting from the first year as defined in the inclusion/exclusion criteria.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Received a single kidney transplant after January 1, 2018
  • Age over 18 years at time of kidney transplant.
  • It was under preemptive strategy.
  • Diagnosed with CMV infection/disease within the first 12 months after kidney transplant.
  • Follow-up information is available in medical records for at least 12 months after confirmation of CMV infection, or even loss of the allograft, death of the recipient or loss of follow-up of the receiver, when/if applicable.

Exclusion criteria

Exclusion Criteria:

  • Diagnosed as a carrier of the (HIV+), virus and/or before kidney transplantation.
  • Participation in any interventional study during the period between kidney transplantation and a period of 12 months after CMV diagnosis.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2023 (actual). Primary completion is estimated for Jul 2024, 9 months after the start.

Of 30 observational studies under Cytomegalovirus Infections, half reached primary completion within 45 months of starting (the median), counting those still running; a quarter within 34 and three quarters within 61. This study's planned 9 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 22, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
