This Phase II study will evaluate whether the addition of abacavir to an anti-HIV drug combination that includes at least three approved antiretroviral drugs can lower viral load levels to undetectable (below 50 copies/mL). Investigators will also evaluate side effects in this double-blinded, placebo-controlled study. Participants will be assigned to one of two treatment groups: one group will add abacavir 60 to 90 days after having started an antiretroviral regimen; the second group will add a placebo (sugar pill). Regular clinic visits are required. Participants whose viral loads do not respond to treatment will be discontinued from the blinded part of the study. If treatment failure occurs after week 12 of the study, participants will be offered the opportunity to take abacavir until the study's conclusion (week 36). Eligible participants must have been taking an accepted anti-HIV regimen composed of at least three antiretroviral drugs for at least 28 days before study entry. Participants must also have a viral load greater than 500 copies/mL but less than 10,000 copies/mL.

This Phase III, open-label, and randomized study will help to determine whether the use of IL-2, in combination with an anti-HIV regimen, can reduce the risk of serious AIDS-related infections and/or prolong survival in HIV-infected people. IL-2 is a protein produced by lymphocytes. In various clinical trials, IL-2 has demonstrated a capacity for increasing CD4 cell counts. Study participants will be randomly divided into one of two treatment groups. Group 1 will take a combination antiretroviral regimen without IL-2. Group 2 will take a combination antiretroviral regimen plus IL-2, administered as an injection under the skin twice a day for five days. The five-day cycle will be repeated every eight weeks for three cycles; subsequent cycles will be based on individual response. Regular physical examinations and blood tests are included and participants will be taught how to self-administer IL-2. The study will last for six years, with regular clinic visits required. Eligible participants must have a CD4 cell count of at least 300 cells/mm3 and be taking a stable (unchanged) combination anti-HIV regimen. Exclusion criteria include prior use of IL-2, a history of AIDS-defining illnesses, and pregnancy. The study is being offered at the National Institute of Allergy and Infectious Diseases (NIAID) in Bethesda (1-800-411-1222). (00-I-0071)
This Phase II trial will evaluate three doses of T-20, an experimental anti-HIV fusion inhibitor, in combination with abacavir (an NRTI), ritonavir, and amprenavir (PIs), and efavirenz (an NNRTI). Participants will be assigned to one of four treatment groups. Three of the groups will take abacavir, amprenavir, ritonavir, and efavirenz, plus three different doses of T-20.

This Phase II, double-blinded, and placebo-controlled study will evaluate whether the addition of hydroxyurea to an anti-HIV combination regimen that includes ddI can suppress the virus in people with advanced HIV disease who have experienced virological failure while taking a first or second triple combination regimen. Participants will be tested to determine their response to ddI. Anti-HIV drug combinations will be selected based on individual responses to ddI and history of prior antiretroviral use. The study will last for 48 weeks. At week five, all participants willing to start anti-HIV treatment will be assigned at random to one of three treatment groups. The first group will take their selected anti-HIV drugs in combination with a hydroxyurea placebo and ddI. The second group will take their anti-HIV drugs plus ddI, and will start hydroxyurea after a delay of eight weeks; the third group will take their anti-HIV drugs plus ddI and hydroxyurea.
Eligible participants must have been unable to achieve viral suppression while taking one or two anti-HIV regimens that included at least three anti-HIV drugs. They must also have been on a stable triple anti-HIV combination regimen for at least sixteen weeks prior to study entry. In addition, eligible participants must have a CD4 cell count below 300 cells/mm3 within 45 days of study entry and agree to use two methods of effective birth control while on study drugs and for at least 60 days after stopping the drugs.

Laboratory tests will include CD4 cell counts, viral load, toxicity and side effects, HIV-specific immune responses, and viral resistance. Eligible participants must have a CD4 cell count of at least 300 cells/mm3 within 30 days of study entry; for participants in cohort 2, the lowest documented CD4 cell count must be no fewer than 200 cells/mm3. In addition, eligible participants must be taking an antiretroviral regimen that includes at least two NRTIs and an NNRTI or a PI, and have at least one viral load test below 500 copies/mL, with a confirmatory viral load of less than 50 copies/mL prior to study enrollment. Exclusion criteria include no history or laboratory evidence of hepatitis B (HBV) infection, no active substance abuse, no evidence of clinical resistance to approved antiretrovirals, and no use of nevirapine for participants interested in cohort 1. The study is being offered at NIAID in Bethesda (800-411-1222). (00-I-0020)
This randomized study will evaluate the benefits and/or drawbacks of changing to a new antiretroviral regimen immediately or after first taking a four-month treatment "holiday" in people who appear to be resistant to several anti-HIV medications. All interested participants will receive a genotypic screening test; if the test reveals multidrug-resistant virus, they will be considered eligible for the study. Eligible participants will then receive phenotypic testing to determine which drugs they are resistant or sensitive to, and be assigned at random to either start a new antiretroviral regimen or stop taking all anti-HIV medications for a period of no more than four months. After four months, they will start a new antiretroviral regimen. Clinic visits are required during the two-year study period. In addition to the criteria already mentioned, eligible participants must have a viral load greater than 10,000 copies/mL and be taking a stable antiretroviral regimen for at
least 14 days prior to genotypic testing. Exclusion criteria include opportunistic infections (OIs), vaccinations administered 14 days prior to genotypic testing, pregnancy, and breast-feeding. Study locations include Atlanta (404-876-2317), Chicago (773-244-5800), Denver (303-436-7195), New Jersey (973-483-3444), New Orleans (504-584-1971), and Portland (503-229-8428). (CPCRA 064)
This Phase III study will evaluate if valacyclovir is a safe and effective treatment for anogenital herpes (herpes simplex virus [HSV] infection of the anus and external genitals) in people with HIV. Participants will be assigned at random to receive either valacyclovir or placebo twice a day for six months, with monthly clinic visits required.

(104C; HS230018)
This Phase II/III study will compare the effectiveness, safety, and tolerability of two hepatitis C treatments in people coinfected with HCV and HIV to determine if pegylated interferon (PEG Intron) plus ribavirin, an antiretroviral, is more effective than interferon alfa-2a (IFN alfa-2a) plus ribavirin. PEG Intron is a modified formulation of IFN alfa-2a with a longer half-life that reduces frequency of treatment. Participants will be assigned at random to one of two treatment groups for up to 48 weeks of treatment. Group 1 will take IFN alfa-2a plus ribavirin, and group 2 will take PEG Intron plus ribavirin. Laboratory tests will be administered at week 24 to monitor participant response to treatment; if treatment is considered ineffective, it will be discontinued. If treatment is effective, it will be continued for an additional 24 weeks. Eligible participants must have chronic liver disease consistent with HCV infection and meet one of the following sets of guidelines: 1) CD4 cell count greater than 100 cells/mm3, viral load below 10,000 copies/mL within 35 days prior to study entry, stable antiretroviral treatment for 12 weeks prior to study entry, with intent to continue treatment for 24 weeks after study entry; or 2) CD4 cell count greater than 300 cells/mm3 within 35 days prior to study entry, no antiretroviral treatment 12 weeks prior to study entry, and no intention of starting treatment within the first 24 weeks of study entry. Exclusion criteria include a positive test for HBV, severe mental illness, and prior use of interferon or oral ribavirin.

This study will evaluate the combination regimen of the nucleoside analogs ddI EC and d4T plus two PIs, indinavir and ritonavir, in women with prior use of both NRTIs and NNRTIs, but not PIs. The 48-week study will determine if the above drugs cause changes in body fat, as well as glucose, insulin, cholesterol, or triglyceride blood levels, and compare those changes by gender. The study will also attempt to determine if there is a gender difference in safety, tolerability, and efficacy of the regimen. Participants will be assigned to receive indinavir, ritonavir, d4T, and standard (noncoated) ddI. After four weeks of treatment, all participants will switch from standard ddI to ddI EC; there are no placebos in the study. Clinic visits are required every two weeks; one all-day visit may also be required. In addition, hormone levels will be measured in some participants to evaluate the effect that PI therapy may have on women. The organization Women Alive will provide peer support to participants. Although there is no CD4 cell requirement, eligible participants must have a viral load of at least 500 copies/mL and prior NNRTI and NRTI experience, excluding more than 30 days' use of ddI and d4T. Exclusion criteria also include more than 14 days' use of a PI. Study locations include Berkeley (510-204-4109) and Chapel Hill (919-966-7883).
