简要总结
This is a single dose, phase I study to evaluate the safety/tolerance and the immunogenicity of HIV-1 Immunogen, gp120-depleted inactivated HIV-1 preparation in Incomplete Freund's Adjuvant (IFA), in children with HIV-1 infection. A total of 32 children with HIV-1 infection will be enrolled in the study. Arm A of the study will enroll children who have no or moderate immune suppression at the time of study entry as defined by CDC classification and who have no history of and do not require antiretroviral therapy. Antiretroviral treatment given for less than 7 weeks (up to 6 weeks and 6 days) prior to entry will be considered as "no history" of treatment (treatment naive). Arm B will enroll children who have no or moderate immune suppression at the time of study entry as defined by CDC classification and who are on or have received antiretroviral treatment for more than 7 weeks. In order to assess the age-associated impact on the immune response rate, we plan to continue to attempt to enroll infants younger than 24 months of age. Children in each arm will receive 10 units of HIV-1 Immunogen intramuscularly at 0, 3, 6, 9, and 12 months.
Antiretroviral treatment will commence once patients meet the criteria for an initiation of the treatment as defined in the protocol. All antiretroviral agents that are currently approved by FDA for clinical indications in HIV-1-infected children (pediatric labeling) are permitted in the protocol. If the child has been receiving a single agent other than ddI, or has been on investigational antiretroviral agents, his/her antiretroviral therapy will have to be changed to an optimal combination regimen of the approved agents at least 6 weeks prior to the enrollment.

入选标准
- •for army B must have plasma HIV-1 RNA levels less than 5 X 10(4) copies/ml while receiving optimal antiretroviral therapy, confirmed at least two different time points 2 to 4 weeks apart, showing no sign of increase (increment less than 0.5 log(10). If the child has been previously treated with antiretroviral drugs for more than 7 weeks (therefore not eligible for arm A) and is currently off drugs, he/she will have to be placed on optimal antiretroviral agents and will have to maintain viral RNA levels below 5 X 10(4) copies/ml prior to the entry.
- •Each child enrolled in arm B has to be on constant regimen of antiretroviral treatment for at least 6 weeks-prior to the first inoculation. Children in immune categories 1 and 2 at the time of study entry will be allowed to enroll.
- •Not critically ill or clinically unstable or no presence of active infection requiring on-going (or induction) therapy.
- •No evidence of severe immune suppression at the time of study entry as defined by CDC classification system, Immune Category
- •For children younger than 24 months of age, no plasma HIV-1 RNA levels greater than or equal to 5 x 10(4) copies/ml despite appropriate antiretroviral treatment, confirmed at least at two different time points 2 to 4 weeks apart.
- •No use of tube feeding or intravenous hyperalimentation itself will be allowed as long as it is a stable regimen.
- •No administration of chemotherapeutic agents, or use of immunomodulating agents such as corticosteroids, interferons, G-CSF, EPO, growth hormone (GH) or IVIG within one month of enrollment.
- •No abnormalities of laboratory findings within one month of enrollment including the following: SGPT or SGOT greater than 5 times the normal value; Total bilirubin greater than 3 times normal; BUN or creatinine greater than 2 times normal; Total WBC greater than 150/mm(3) or ANC greater than 750/mm(3); Hemoglobin greater than 8.0 g/dl (transfusions are allowed); Platelet count greater than 100,000/mm(3).
- •Not pregnant or not planning to become pregnant.
- •No active substance abuse.
- •Able to comply with the study requirements for scheduled evaluations such as periodic clinic visits or blood sampling.
