A Phase I, Multicenter, Randomized, Double-Blind, Placebo-Controlled HIV-1 Vaccine Trial to Evaluate the Safety and Immunogenicity of MN Recombinant Soluble gp120/HIV-1 (rsgp120/HIV-1) (Genentech) in Combination With QS21 Adjuvant and/or Alum in Healthy Adults

Completed · Phase 1

Conditions studied: HIV Infections

In brief

To extend the evaluation of safety and immunogenicity of MN recombinant soluble gp120/HIV-1 (MN rsgp120/HIV-1) in combination with QS21 with or without alum and on two different vaccination schedules. Recent animal studies indicate that immunizing with MN rsgp120/HIV-1 in combination with QS21 on a 0, 1, 2 month schedule results in a more rapid rise in binding and neutralizing antibody response than on a 0, 1, 6 month schedule. Such an effect may be particularly desirable in vaccine delivery. This study compares these two delivery schedules using the unadjuvanted vaccine formulation rsgp120/HIV-1 with or without addition of alum.

Who can join

Age: 18 and older, up to 60. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Subjects must have:
• Normal history and physical exam.
• HIV negative by ELISA within 8 weeks of immunization.
• Absolute CD4 count >= 400 cells/mm3.
• Normal urine dipstick with esterase and nitrite.

You may not qualify if…

• Co-existing Condition:
• Subjects with the following symptoms or conditions are excluded:
• 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 false positive or due to a remote (> 6 months) treated infection are eligible.
• Active tuberculosis. NOTE: Subjects with a positive PPD and normal chest x-ray showing no evidence of TB and not requiring isoniazid therapy are eligible.
• Subjects with the following prior conditions are excluded:
• History of immunodeficiency, autoimmune disease, or use of immunosuppressive medications.
• History of anaphylaxis or other serious adverse reactions to vaccines.
• History of allergy to thimerosal.
• 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 subunit or killed vaccines, such as influenza or pneumococcal, are allowed but should be given at least 2 weeks prior to HIV immunizations.)
• Experimental agents within 30 days prior to study entry.
• Prior HIV vaccines.
• Prior Treatment:
• Excluded:
• Receipt of blood products or immunoglobulin within the past 6 months.
• Risk Behavior:
• Subjects are NOT excluded on the basis of HIV risk behaviors, but AVOIDANCE of any activity that may expose subject to HIV (e.g., unprotected sex or needle sharing) is STRONGLY RECOMMENDED.
