Trial summary

The purpose of this research study is to test the safety and tolerability of four new investigational Cytomegalovirus (CMV) vaccines (Towne-Toledo 1, 2, 3, 4) in healthy male volunteers who are CMV negative. CMV is a common virus, infecting 50-80% of adults in the United States by the age of twenty-one. Read more about this study

About this study

Official title: A Dose Escalation Study to Assess the Safety and Immunogenicity of Four Live Attenuated Human Cytomegalovirus(HCMV) Vaccines in Healthy Adults Without Prior Immunity.

The purpose of this research study is to test the safety and tolerability of four new investigational Cytomegalovirus (CMV) vaccines (Towne-Toledo 1, 2, 3, 4) in healthy male volunteers who are CMV negative. CMV is a common virus, infecting 50-80% of adults in the United States by the age of twenty-one. CMV does not usually cause illness in adults or children. However, CMV can be a cause of deafness and mental retardation in a child if a mother is infected during pregnancy. It also can be a serious illness in patients with impaired immunity (decreased ability to fight infection).

Read the detailed description

A total of thirty six participants will be enrolled. The first 12 participants will be randomized into four groups. Four groups will receive one of the four investigational vaccines. The four investigational HCMV vaccine candidates will be administered subcutaneously to 3 volunteers at 10 pfu (the lowest dose to be used). The safety and tolerability of the four investigational HCMV vaccine candidates will be monitored closely for a period of 12 weeks following vaccination at this dose. Investigational vaccines that are found to be safe and well tolerated at a dose of 10pfu will be administered to 3 additional individuals at 102 pfu and then at 103 pfu. Safety and tolerability will be evaluated at each dose level by monitoring clinical signs and symptoms, laboratory parameters and virus detection in the blood, urine, and saliva. After the 12-week safety-monitoring period, participants will be followed for the remainder of one year to assess long-term safety and immunogenicity of the investigational vaccines.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing cmv vaccine in people with Cytomegalovirus, run by CMV Research Foundation 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 6 inclusion and 17 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 19 May 2015. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Safety (time frame: 2 years). 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 NCT01195571, which also lists 1 linked publication.

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 19 May 2015.
