Anti-HIV Drug Regimens and Treatment-Switching Guidelines in HIV Infected Children
A Phase II/III Randomized, Open-Label Study of Combination Antiretroviral Regimens and Treatment-Switching Strategies in HIV-1-Infected Antiretroviral Naive Children Between 30 Days and 18 Years of Age

Little is known about what treatment combinations are best for HIV infected children. This study will examine the long-term effectiveness of different anti-HIV drug combinations in children and strategies for switching treatment if the first treatment does not work. The study will enroll children who have not previously taken anti-HIV medication. Participants in this study will be recruited in both the United States and in Europe.

Some European children may also enroll in a substudy that will observe changes in body fat in children taking anti-HIV medications.

Antiretroviral therapy in children aims to prolong clinical and immunologic health. Currently, there are no data defining a particular highly active antiretroviral therapy (HAART) strategy as the optimal first-line therapy for children. This study will evaluate the long-term efficacy of two HAART regimens used as initial therapy: 1) two nucleoside reverse transcriptase inhibitors (NRTIs) plus a protease inhibitor (PI), and 2) two NRTIs plus a nonnucleoside reverse transcriptase inhibitor (NNRTI). It will also evaluate different strategies for switching therapy when the initial regimen fails. The long-term nature of this study should clarify whether early switching of therapy improves immunologic and virologic outcomes, or results in a more rapid exhaustion of treatment options. The study will be conducted in the United States and in Europe.

Participants in this study will have a CD4 cell count and viral load test during a screening visit. Participants will have an entry visit that will include blood and urine tests, a neurologic exam, a chest X-ray, and a behavioral and learning development exam. Participants will then be randomly assigned to one of four groups: Groups 1A and 1B will receive two NRTIs plus a PI; Groups 2A and 2B will receive two NRTIs plus an NNRTI. The medications allowed in the study are: abacavir, didanosine, emtricitabine, emtricitabine/tenofovir disoproxil fumarate, lamivudine, lamivudine/zidovudine, stavudine, tenofovir disoproxil fumarate, zalcitabine, and zidovudine (NRTIs); efavirenz and nevirapine (NNRTIs); efavirenz/emtricitabine/tenofovir disoproxil fumurate (NNRTI/NRTI); and amprenavir,atazanavir, darunavir, fosamprenavir calcium, indinavir, lopinavir/ritonavir, nelfinavir, saquinavir, ritonavir, and tipranavir (PIs).

For participants whose initial regimen fails, or who experience clinical disease progression (indicated by the development of a new CDC Category C diagnosis) or other clinical disease progression at or after Week 24 of first-line therapy, second-line therapy will be strongly encouraged. (However, if poor adherence is suspected as a possible reason for an increase in HIV viral load, the site and the clinician should try to improve patient adherence and obtain additional confirmatory viral load values within a five-week time frame.) In second-line therapy, participants who initially took NRTIs with a PI will switch to NRTIs and an NNRTI. Participants who initially took NRTIs and an NNRTI will switch to NRTIs and a PI. The timing of the switch will be based on the participant's group: Groups 1A and 2A will switch to second-line treatment when viral load is 1,000 copies/ml or greater; Groups 1B and 2B will switch to second-line treatment when viral load is 30,000 copies/ml or greater. Participants who fail second-line therapy will discontinue study treatment and will be offered the best available therapy at the discretion of the clinician.

Participants will have study visits at Weeks 2, 4, 8, 12, 16, 24, and every 12 weeks thereafter until the drug regimen is switched to second-line treatment. Participants will then have a re-entry visit and the schedule of visits will restart. Participants will be in the study between 4 and 8 years, depending on when they enroll. All study visits will include medical history, a physical exam, and blood collection. Urine collection will occur at most visits. Participants will be asked to complete adherence questionnaires and will undergo neuropsychological assessments at selected visits.

All participants in this study are encouraged to coenroll in ACTG 219C, Long-Term Effects of HIV Exposure and Infection in Children. Participants in the European portion of the study may be asked to enroll in a substudy to observe the development and progression of lipodystrophy syndrome in children.
