Purpose
To evaluate, in HIV-negative volunteers, the safety and immunogenicity of ALVAC-HIV MN120TMGNP (vCP300) followed by or combined with boosting using rgp120/HIV-1SF2. To compare ALVAC-HIV vCP300 with ALVAC-RG rabies glycoprotein (vCP65) as a control. To evaluate an accelerated immunization schedule at 0, 1, 3, and 6 months versus 0, 1, 6, and 9 months.
The combination of a live recombinant primer followed by a subunit boost has the potential to induce not only cytotoxic T lymphocytes but also neutralizing antibody.

| Official Title: | A Phase I Safety and Immunogenicity Trial of Live Recombinant Canarypox ALVAC-HIV vCP300 and HIV-1 SF-2 rgp120 in HIV-1 Uninfected Adult Volunteers |
| Estimated Enrollment: | 140 |
| Study Completion Date: | January 1999 |
The combination of a live recombinant primer followed by a subunit boost has the potential to induce not only cytotoxic T lymphocytes but also neutralizing antibody.
Volunteers are randomized to one of seven groups to receive immunizations with either ALVAC-HIV vCP300 or ALVAC-RG vCP65 (control), plus simultaneous or sequential boosting with rgp120/HIV-1SF2 or placebo. Immunizations are given at 0, 1, 6, and 9 months or 0, 1, 3, and 6 months. Volunteers are followed for at least 24 months.
Eligibility| Ages Eligible for Study: | 18 Years to 60 Years |
| Genders Eligible for Study: | Both |
| Accepts Healthy Volunteers: | Yes |
Inclusion Criteria
Volunteers must have:
- Normal history and physical exam.
- ELISA and Western blot negative for HIV.
- CD4 count >= 400 cells/mm3.
- Normal urine dipstick with esterase and nitrite.
- Lower risk sexual behavior.
Exclusion Criteria
Co-existing Condition:
Subjects 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.
- 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.
Subjects 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.
