This study allows direct comparison of gp160 administered intradermally with alum-adjuvanted intramuscular preparation with respect to immunogenicity in HIV seropositive patients.\n\nEach of 10 volunteers is initially injected with the lowest dose of intradermal antigen and the injection site observed at 24, 48, and 72 hours. Clinical and laboratory evaluations are performed 4 and 8 weeks after inoculation. If there is not delayed-type hypersensitivity (DTH) response to the lowest dose, patients are retested at the next dose 8 weeks later and dose escalation is continued at 8-week intervals until (1) there is a DTH response to gp160; or (2) the maximum anticipated dose is reached. In any individual, a higher dosage is administered only if there is no evidence of DTH response. Patients with a DTH may continue to receive booster injections of gp160 at 3 month intervals up to week 70. Patients with an immune response but no DTH may continue to receive injections for an additional year. A second group of 10 asymptomatic individuals are recruited and inoculated with the dose found to bring about either a DTH or lymphocyte proliferative response in 7 of the 10 patients in the first group. If the second group confirms the results of the initial group, the study is amended to include patients with AIDS-related complex (ARC) and AIDS."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "minimumAge"=>"18 years", "healthyVolunteers"=>false, "eligibilityCriteria"=>"Inclusion Criteria\n\nConcurrent Medication:\n\nAllowed:\n\n* Acute use (\\< 14 days) of acyclovir for Herpes simplex virus infections or ketoconazole for symptomatic Candida infections.\n\nPatients must have the following:\n\n* Asymptomatic HIV seropositivity.\n* Patients with CD4 counts of 400 - 500 cells/mm3 must be informed of the recommended zidovudine (AZT) therapy and sign an informed consent statement declining AZT therapy.\n\nExclusion Criteria\n\nCo-existing Condition:\n\nPatients with the following conditions or symptoms are excluded:\n\n* Systemic symptoms other than lymphadenopathy thought to be due to HIV infection including:\n* Fatigue/malaise of \\> 1 month duration that interferes with normal activities.\n* Fever of \\> 100 degrees F persisting for \\> 15 in a 30-day interval without definable cause.\n* Involuntary weight loss in excess of 10 pounds or \\> 10 percent of normal weight within a 6-month interval.\n* Diarrhea (\\> 3 stools/day) persisting for more than 30 days without definable cause.\n* Recurrent oral candidiasis.\n* Multidermatomal herpes zoster.\n* Biopsy proven hairy leukoplakia.\n* Evidence of clinically significant central nervous system dysfunction as assessed by neurological exam.\n\nConcurrent Medication:\n\nExcluded:\n\n* Antiretroviral agents of proven or potential efficacy.\n* Any potential immunoenhancing or immunosuppressive drugs.\n\nPatients with the following are excluded:\n\n* Known hypersensitivity to insect cells or baculovirus.\n* Abnormal chest x-ray taken within 3 months of study entry.\n* Systemic symptoms other than lymphadenopathy thought to be due to HIV infection as listed in the patient exclusion coexisting diseases or complications.\n* Evidence of clinically significant central nervous system dysfunction as assessed by neurological exam.\n* Unwilling or unable to give written informed consent.\n\nPrior Medication:\n\nExcluded within 90 days of study entry:\n\n* Zidovudine (AZT).\n* Didanosine (ddI).\n* Any potential antiretroviral.\n* Immunomodulating agents.\n\nActive substance abuse (either continuing daily alcohol abuse or intravenous drug use)."}, "identificationModule"=>{"nctId"=>"NCT00000667", "briefTitle"=>"A Phase I/II Dose Escalation Study of Intradermal gp160 to Evaluate Safety, Delayed Type Hypersensitivity (Skin Test) Responses and Immunogenicity in Asymptomatic HIV Seropositive Patients With More Than 400 CD4+ Cells", "organization"=>{"class"=>"NIH", "fullName"=>"National Institute of Allergy and Infectious Diseases (NIAID)"}, "officialTitle"=>"A Phase I/II Dose Escalation Study of Intradermal gp160 to Evaluate Safety, Delayed Type Hypersensitivity (Skin Test) Responses and Immunogenicity in Asymptomatic HIV Seropositive Patients With More Than 400 CD4+ Cells", "orgStudyIdInfo"=>{"id"=>"ACTG 148"}, "secondaryIdInfos"=>[{"id"=>"11123", "type"=>"REGISTRY", "domain"=>"DAIDS ES Registry Number"}]}, "armsInterventionsModule"=>{"interventions"=>[{"name"=>"gp160 Vaccine (MicroGeneSys)", "type"=>"BIOLOGICAL"}]}, "contactsLocationsModule"=>{"locations"=>[{"zip"=>"10016", "city"=>"New York", "state"=>"New York", "country"=>"United States", "facility"=>"NY Univ.
