Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 45 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Between 18 and 45 years of age
  • Written informed consent
  • Female volunteers must be using contraception and should avoid becoming pregnant for the duration of the vaccination course
  • Serology: Groups 1, 3, 4 and 5: HSV-1 AND HSV-2 seronegative (by gD2 ELISA); Group 2: HSV seropositive by gD2 ELISA before entry

Exclusion Criteria:

  • Any previous vaccination against Herpes simplex.
  • Any previous administration of MPL.
  • Pregnancy or lactation.
  • Patient is immuno-compromised or is receiving immuno-modifying therapy of any kind.
  • Clinical signs of acute or febrile illness at the time of entry into the study.
  • Any administration of immunoglobulins during the vaccination course or within one month of vaccination.
  • Any vaccination within one week of study vaccination.
  • Previous known hypersensitivity to vaccination or to any component of the vaccine.
  • Simultaneous participation in any other clinical trial with an investigational drug or vaccine. Subjects currently in a follow-up period of a vaccine study can be included.
  • Recent history of alcoholism or drug abuse (within the past 6 months).
  • Life-threatening or serious cardiac (NYHA grades III-IV), gastrointestinal, hepatic, renal, hematological or immunological disorder which, in the opinion of the investigator, would preclude entry into the study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
To evaluate in initially HSV-seronegative subjects the GMT's and the seroconversion rates of anti-gD2 antibodies (ELISA)
Time Frame: After the second and third doses of each vaccine
After the second and third doses of each vaccine
To evaluate in initially HSV-seronegative subjects, the GMT and the seropositivity rate of anti-HSV-2 neutralizing antibodies
To evaluate the cell-mediated immune (CMI) response (lymphoproliferation, secretion of interleukin 2 and γ interferon)
Time Frame: After the second and third dose of each vaccine formulation
After the second and third dose of each vaccine formulation
To evaluate, in initially seronegative subjects and in initially seropositive subjects, the incidence and intensity of solicited local and general signs and symptoms
Time Frame: During 3 days after each dose of each vaccine
During 3 days after each dose of each vaccine
To evaluate in initially seropositive subjects, the GMT and the seropositivity rate of anti-gD2 antibodies (ELISA) and of anti-HSV-2 neutralizing antibodies
Time Frame: After 2 and 3 doses of vaccines
After 2 and 3 doses of vaccines

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 1995

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
January 1, 1997

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
