What is being measured

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

  1. Change in %CD38+ Human Leukocyte Antigen-D-related (HLA-DR)+ CD8+ T Cells From Baseline to Week 8.

    The percentage of activated (CD38+ HLA-DR+) CD8+ T cells was measured on fresh whole blood at screening/baseline. T cell activation was measured on peripheral blood mononuclear cells (PBMCs)in batch at the end of the study.

    Measured: Baseline, 8 weeks

Secondary outcomes (5)
  1. Change in CMV DNA Shedding From Baseline to Week 8.

    Change in percentage of participants with detectable CMV DNA. Herpesvirus DNA levels were assessed by polymerase chain reaction (lower limit of detection, 150 copies/mL) on saliva and seminal plasma.

    Measured: baseline and week 8

  2. Change in Cluster of Differentiation 4 (CD4) Counts at Week 8

    Measured: Baseline and week 8

  3. Change in Percent of CD38+HLA-DR+ CD8+ T Cells After a 4-week Washout Period

    Change from baseline at week 12

    Measured: Baseline and Week 12

  4. Number of Participants With Positive CMV DNA After a 4-week Washout Period

    Number of Participants with positive CMV DNA at any site at week 12

    Measured: Week 12

  5. Change in CD4 Counts After a 4-week Washout Period

    Change from baseline at week 12

    Measured: Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Valganciclovir in people with HIV Infections and Cytomegalovirus Infections, run by University of California, San Francisco 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 8 inclusion and 9 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 31 Jul 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 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. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 8 Nov 2013). 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?

Change in %CD38+ Human Leukocyte Antigen-D-related (HLA-DR)+ CD8+ T Cells From Baseline to Week 8. (time frame: Baseline, 8 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00264290, which also lists 2 linked publications.

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 31 Jul 2020.
