About this study
Official title: CytoGam® as Adjuvant Therapy to Prevent or Attenuate Human Cytomegalovirus (CMV) Infection and Disease in Solid Organ Transplant Recipients
Cytomegalovirus (CMV) is a significant opportunistic pathogen and a major cause of morbidity and mortality in solid organ transplant recipients. CytoGam - Cytomegalovirus Immune Globulin Intravenous (CMV-IGIV), is an immunoglobulin G containing a standardized amount of antibody against CMV. CytoGam is obtained from pooled adult human plasma that has been selected for high anti-CMV titers. This study will evaluate if administration of CytoGam to organ transplant recipients with CMV infection, along with standard of care antiviral medication, leads to faster clearance of CMV from the blood, prevents the development of antiviral resistance, and decreases the rate of recurrence of CMV infection.
Read the detailed description
Interventional, open-label, single center, pilot study to test the effect of CytoGam on CMV viremia clearance in organ transplant recipients with high CMV viral load and in CMV D+/R- lung and liver transplant recipients with primary CMV infection.
CMV D+/R- lung transplant recipients who develop any level of CMV DNAemia after discontinuation of valganciclovir prophylaxis and who have not yet received antiviral treatment for greater than 14 days will receive one dose of CytoGam. The choice and duration of antiviral therapy will be at the discretion of the treating physician. Patients will be followed until 2 weekly negative CMV PCRs, discontinuation of antiviral, or 1 year from CytoGam infusion, whichever is longer.
CMV D+/R- liver transplant recipients on pre-emptive therapy who develop any level of detectable CMV DNAemia and who have not yet received antiviral treatment for greater than 14 days will receive one dose of CytoGam. The choice and duration of antiviral therapy will be at the discretion of the treating physician. Patients will be followed until 2 weekly negative CMV PCRs, discontinuation of antiviral, or 1 year from CytoGam infusion, whichever is longer.
Recipients of any solid organ transplant who have CMV DNAemia ≥ 50,000 IU/ml, with or without CMV disease, and who have not yet received antiviral therapy for greater than 14 days will receive one dose of CytoGam. The choice and duration of antiviral therapy will be at the discretion of the treating physician. Patients will be followed until 2 weekly negative CMV PCRs, discontinuation of antiviral, or 1 year from CytoGam infusion, whichever is longer.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Cytogam in people with Cytomegalovirus (CMV) Infection, run by Fernanda P Silveira, MD, MS at 1 site in United States.
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 10 inclusion and 7 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: enrolling by invitation, as of the sponsor's last update on 10 Aug 2026. 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 United States. 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.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
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 CMV DNAemia clearance (time frame: 1 year). 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 10 Aug 2026; AzTrials last refreshed its copy on 7 Nov 2026.
