What is being measured

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

  1. Change in Sperm Density From Baseline to the End of Treatment (EOT)

    Sperm density was calculated based on the average of two semen samples. Change was calculated as the sperm density measured at post-baseline visit (EOT) minus (-) the sperm density measured at baseline for each participant. A negative change from baseline indicated a lower sperm density (worsening).

    Measured: Baseline, EOT (Week 28)

Secondary outcomes (26)
  1. Change in Terminal Uridine Nick-End Labeling (TUNEL) Score From Baseline to EOT and End of Follow-up (FU)

    Sperm DNA fragmentation change (chromatin damage) was evaluated based on TUNEL score. Change was calculated as the TUNEL score measured at post-baseline visit (EOT and FU) minus the TUNEL score measured at baseline for each participant. A negative change from baseline indicated a lower TUNEL score. TUNEL score represents percentage of sperm with fragmented DNA; total score ranged from 0 percent (%) to 100%, higher score represents more fragmentation.

    Measured: Baseline, EOT (Week 28), end of FU (Week 52)

  2. Change in TUNEL Score From EOT to End of FU

    Sperm DNA fragmentation change (chromatin damage) was evaluated based on TUNEL score. Change was calculated as the TUNEL score measured at FU minus the TUNEL score measured at EOT for each participant. A negative change from EOT indicated a lower TUNEL score. TUNEL score represents percentage of sperm with fragmented DNA; total score ranged from 0% to 100%, higher score represents more fragmentation.

    Measured: EOT (Week 28), end of FU (Week 52)

  3. Change in Seminal Volume From Baseline to EOT and End of FU

    Seminal volume was calculated based on the average of two semen samples. Change was calculated as the seminal volume measured at post-baseline visit (EOT and FU) - the seminal volume measured at baseline for each participant. A negative change from baseline indicated a lower seminal volume (worsening).

    Measured: Baseline, EOT (Week 28), end of FU (Week 52)

  4. Change in Seminal Volume From EOT to End FU

    Seminal volume was calculated based on the average of two semen samples. Change was calculated as the seminal volume measured at FU - the seminal volume measured at EOT for each participant. A negative change from EOT indicated a lower seminal volume (worsening).

    Measured: EOT (Week 28), end of FU (Week 52)

  5. Change in Sperm Density From EOT to End of FU

    Sperm density was calculated based on the average of two semen samples. Change was calculated as the sperm density measured at FU - the sperm density measured at EOT for each participant. A negative change from EOT indicated a lower sperm density (worsening).

    Measured: EOT (Week 28), end of FU (Week 52)

  6. Change in Sperm Density From Baseline to End of FU

    Sperm density was calculated based on the average of two semen samples. Change was calculated as the sperm density measured at post-baseline visit (FU) - the sperm density measured at baseline for each participant. A negative change from baseline indicated a lower sperm density (worsening).

    Measured: Baseline, end of FU (Week 52)

  7. Change in Total Motility of Sperm From Baseline to EOT and End of FU

    Sperm motility was calculated based on the average of two semen samples. Percent was determined by the calculation of motile sperm/total sperm count. Change was calculated as the sperm motility measured at post-baseline visit (EOT and FU) - the sperm motility measured at baseline for each participant. A negative change from baseline indicated a lower sperm motility (worsening).

    Measured: Baseline, EOT (Week 28), end of FU (Week 52)

  8. Change in Total Motility of Sperm From EOT to End of FU

    Sperm motility was calculated based on the average of two semen samples. Percent was determined by the calculation of motile sperm/total sperm count. Change was calculated as the sperm motility measured at FU - the sperm motility measured at EOT for each participant. A negative change from EOT indicated a lower sperm motility (worsening).

    Measured: EOT (Week 28), end of FU (Week 52)

  9. Change in Sperm Morphology Evaluated as Percentage of Normal Sperm Cells From Baseline to EOT and End of FU

    Sperm morphology was evaluated based on the average of two semen samples. Change was calculated as the sperm morphology measured at post-baseline visit (EOT and FU) - the sperm morphology measured at baseline for each participant. A positive change from baseline indicated an improved sperm morphology.

    Measured: Baseline, EOT (Week 28), end of FU (Week 52)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Valganciclovir in people with Cytomegalovirus Infections, run by Hoffmann-La Roche at 19 sites in 2 countries.

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 5 inclusion and 5 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 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 19 sites in United States, Mexico. 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?

Yes. Results are posted in the registry (first posted 31 Aug 2018). 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 Sperm Density From Baseline to the End of Treatment (EOT) (time frame: Baseline, EOT (Week 28)). 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 31 Aug 2018.
