June 23, 2005 updated by: Chiron Corporation
To evaluate the safety and tolerability of the Chiron vaccine human immunodeficiency virus (HIV) p24(25 or 50 micrograms)/MF59 in healthy HIV-1 seronegative adults. To evaluate the immunogenicity of the HIV p24(50 micrograms)/MF59 vaccine.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study evaluates the safety and immunogenicity of the Chiron vaccine HIV p24/MF59. In Part A, 15 volunteers are randomly assigned to receive either HIV p24/MF59 or a placebo at 0, 1, and 6 months. 10 volunteers receive the vaccine and 5 volunteers receive the placebo. If no serious adverse events are observed within 1 week after the first injection in these first 15 patients, Part B is initiated. In Part B, 25 volunteers are randomly assigned to receive HIV p24/MF59 or a placebo at 0, 1, and 6 months. 20 volunteers receive the vaccine and 5 volunteers receive the placebo.

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 50 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria

Volunteers must have:

  • Good health as determined by medical history, physical examination, and clinical judgment.
  • Negative serology for HIV infection as determined by licensed HIV ELISA test performed within 6 weeks prior to first immunization.
  • In vitro Epstein-Barr virus-immortalized cell line from peripheral blood can be established (required for selected Part B volunteers only).

Exclusion Criteria

Co-existing Condition:

Volunteers with the following symptoms or conditions are excluded:

  • Significant acute systemic infection.
  • Occupational or other responsibilities that would prevent completion of participation in the study.
  • Any condition that might interfere with the evaluation of the study objectives.

Volunteers with the following prior conditions are excluded:

  • History of immunodeficiency, autoimmune disease, or any serious chronic illness.
  • Evidence of psychiatric or medical history or substance abuse that would adversely affect the volunteer's ability to participate in the trial.

  • History of anaphylaxis or other serious adverse reactions to vaccines or vaccine components.

    1. Immunosuppressive medications.

  • Live, attenuated vaccine within 60 days of study entry.

NOTE:

  • Medically indicated subunit or killed vaccines (e.g., influenza or pneumococcal) are not exclusionary but should be given at least 4 weeks before or after HIV immunizations to avoid potential confusion of adverse reactions.
  • Experimental agents within 30 days of study entry.
  • HIV vaccine or MF59 adjuvant. Blood products or immunoglobulins in the past 3 months.

Engaging in high-risk behavior within 6 months of study entry, i.e.:

  • injection drug use, sexual intercourse without a condom with 4 or more partners or with known iv drug user or HIV+ partner, or newly acquired sexually-transmitted disease.
