About this study

Official title: Cell Mediated Immunity as a Guide for Secondary Prophylaxis in SOT Patients With CMV Infection

This study will evaluate whether a test for Cytomegalovirus (CMV) specific cell-mediated immunity can be used to determine whether patients who complete a course of therapy for CMV viremia need secondary antiviral prophylaxis. Subjects that have negative CMV CMI will receive antiviral prophylaxis for 2 months and those with positive CMV CMI will have their prophylaxis stopped.

Read the detailed description

Cytomegalovirus (CMV) is the most important infection in transplant patients and it is a common cause of illness in patients who have undergone a transplant. Serious infections due to CMV can affect many parts of the body including the lungs, the gut, and the liver; when CMV infection becomes serious enough to cause symptoms, it is called CMV disease. Some patients require treatment while others will clear the virus on their own.

QuantiFERON-CMV (QFT-CMV) is a blood test that measures CMV-specific cell-mediated immunity. This test was able to predict that patients with low cell-mediated immunity are at greater risk for developing CMV disease. In this study, QFT-CMV will be used to make a decision regarding CMV treatment. The QFT-CMV test will be performed at the first detection of CMV, at end of antiviral therapy and one month post-therapy. The end-of-therapy results will be available to clinicians and study investigators within one week of collection. Based on the result, a decision will be made to continue with prolonged antiviral therapy. Patients that show weak cell-mediated immunity against CMV will be given secondary antiviral prophylaxis, while patients with good cell-mediated immunity will have their therapy stopped. Patients will continue to be monitored three months after the last QFT-CMV test for recurrent CMV viremia.

This study will also attempt to evaluate the predictive value of the QuantiFERON-Monitor (QFT-Monitor) assay. QFT-Monitor is a recently developed non-pathogen specific immune assay: it is based on immune activation of both innate and adaptive immunity. The investigators hypothesize that stimulation of both the innate and adaptive immunity may predict global immune function and also be predictive of CMV reactivation. The investigators plan to perform the QFT-Monitor assay in parallel to the QFT-CMV test to determine the test characteristics and cut-off values in predicting global immune function. This test will be collected and tested in batches. Therefore, the results will not influence clinical decisions.

Questions about this trial

What is this clinical trial studying?

A study testing Valganciclovir or Ganciclovir in people with Cytomegalovirus Viraemia, run by University Health Network, Toronto at 1 site in Canada.

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 3 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 21 Sep 2017. 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 Canada. 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?

Virologic recurrence or disease recurrence (time frame: 6 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 21 Sep 2017.
