To evaluate the safety and immunogenicity of an accelerated schedule of recombinant canarypox vaccine ALVAC-HIV MN120TMG (vCP205) versus control followed by boost with rgp120/HIV-1 SF2 vaccine in HIV-negative volunteers.
Frequent injections of ALVAC-HIV vCP205 may result in more rapid induction of cytotoxic T-lymphocytes. This trial will evaluate whether an accelerated vaccination schedule can produce immunological responses comparable to those obtained in other trials of ALVAC-HIV vCP205.

Official Title: | A Phase I Safety and Immunogenicity Trial of Live Recombinant Canarypox ALVAC-HIV (vCP205) and HIV-1 SF-2 rgp120 in HIV-1 Uninfected Volunteers to Evaluate Accelerated Vaccine Schedules |
Estimated Enrollment: | 34 |
Study Completion Date: | December 1997 |
Frequent injections of ALVAC-HIV vCP205 may result in more rapid induction of cytotoxic T-lymphocytes. This trial will evaluate whether an accelerated vaccination schedule can produce immunological responses comparable to those obtained in other trials of ALVAC-HIV vCP205.
Volunteers are randomized to receive immunization with either ALVAC-HIV vCP205 or ALVAC-RG rabies glycoprotein (vCP65) at days 0, 7, 14, and 21, followed by boost with rgp120/HIV-1 SF2 at days 28 and 84. A third cohort receives ALVAC-HIV vCP65 on the same schedule followed by boost with placebo.

Accepts Healthy Volunteers: | Yes |
Inclusion Criteria
Volunteers must have:
- Normal history and physical exam.
- Negative ELISA and Western blot for HIV.
- CD4 count >= 400 cells/mm3.
- Normal urine dipstick with esterase and nitrite.
- Lower-risk sexual behavior.
Exclusion Criteria
Co-existing Condition:
Volunteers with the following symptoms or conditions are excluded:
- Positive hepatitis B surface antigen.
- Medical or psychiatric condition (such as recent suicidal ideation or present psychosis) that precludes compliance.
- Occupational responsibilities that preclude compliance.
- Active syphilis. NOTE: Subjects with serology documented to be a false positive or due to a remote (> 6 months) treated infection are eligible.
- Active tuberculosis. NOTE: Subjects with a positive PPD and a normal chest x-ray showing no evidence of TB and not requiring isoniazid therapy are eligible.
- Allergy to egg products or neomycin.
- Occupational exposure to birds.
Volunteers with the following prior conditions are excluded:
- History of immunodeficiency, chronic illness, autoimmune disease, or use of immunosuppressive medications.
- History of anaphylaxis or other serious adverse reactions to vaccines.
- Prior immunization against rabies.
- History of serious allergic reaction to any substance, requiring hospitalization or emergent medical care (e.g., Stevens-Johnson syndrome, bronchospasm, or hypotension).
- Prior psychiatric condition (such as history of suicide attempts or past psychosis) that precludes compliance.
- History of cancer unless there has been surgical excision that is considered to have achieved cure.
Prior Medication:
Excluded:
- Live attenuated vaccines within 60 days prior to study entry. NOTE: Medically indicated killed or subunit vaccines (e.g., influenza, pneumococcal) do not exclude if administered at least 2 weeks from HIV immunizations.
- Experimental agents within 30 days prior to study entry.
- Prior HIV vaccines.
- Prior rabies immunization.
Prior Treatment:
Excluded:
- Blood products or immunoglobulin within 6 months prior to study entry. Identifiable high-risk behavior for HIV infection, such as
- injection drug use within past 12 months.
- higher- or intermediate-risk sexual behavior.
