NCT01195571

Brief 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. 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).

  • b) HCMV seronegative. c) HIV seronegative. d) Hepatitis B surface antigen negative. e) No evidence of active hepatitis C infection by serologic evaluation. f) HCMV culture negative (to be determined by shell vial or routine culture of urine, blood and saliva collected at the screening visit).

  • h) Available by telephone or pager for one year following vaccination. i) Willing and able to comply with the requirements of the protocol and to properly complete participant diaries.
  • j) Signed informed consent and completed social/demographic questionnaire. k) Willing to forego blood, bone marrow or whole organ donation for 1year post vaccination.
  • l) Willing to forego enrollment in studies of other investigational agents for one year following vaccination.

You may not qualify if:

  • Significant acute or chronic infection at the time of vaccination.
  • Household contact with an immunosuppressed individual.
  • History of anaphylaxis or severe vaccine reaction.
  • Vaccination with a live vaccine within the past month or an inactivated vaccine within two weeks prior to vaccination, or plan to receive any vaccine within two months following vaccination.
  • Seropositive sexual partner who desires to become pregnant within one year following vaccination, currently is pregnant, or is currently breast feeding.
  • Has a close contact who is CMV seronegative or who is ineligible or chooses not to participate in the study.
  • Received blood products in proceeding three months or expects to receive blood products within the following year.
  • A childcare provider.
  • A health care provider who routinely comes in contact with pregnant women or immunologically compromised persons.
  • Any condition which, in the opinion of the investigator, may interfere with adherence to the protocol or make it inadvisable to enroll the participant.
  • Currently participating in a study of any other experimental or investigational agent, or has participated in such a study within a month of vaccination.
  • Previous vaccination with an investigational HCMV vaccine.
  • Treatment with excluded antiviral or immunosuppressive drugs (Appendix D) within one month prior to vaccination.
  • Expected use of antiviral or immunosuppressive agents within two months following vaccination.
