All Clinical Trials for Lamivudine; Nevirapine; Zidovudine

Trial ID Title Status Sponsor Phase Start Date Summary
NCT00000896 ↗ A Study to Compare the Effectiveness of a Four Drug Anti-HIV Regimen Given Alone or in Combination With GM-CSF or IL-12 to HIV-Positive Patients Completed National Institute of Allergy and Infectious Diseases (NIAID) N/A 1969-12-31 The purpose of this study is to examine how the level of HIV is reduced in the blood when anti-HIV therapy is initiated. This study will also evaluate whether adding GM-CSF or IL-12 to the anti-HIV drug regimen will increase the rate that HIV is reduced. The anti-HIV drugs used in this study will include lamivudine (3TC), zidovudine (ZDV), indinavir (IDV), nevirapine (NVP), and stavudine (d4T). All have been used successfully to treat HIV. GM-CSF has been used to treat certain blood disorders; it will be used as an experimental drug in this study. IL-12 (interleukin-12) is a protein found naturally in the body that is thought to boost the immune system. Although GM-CSF and IL-12 have no direct effect against HIV, these drugs may improve the ability of the immune system to fight the virus.
NCT00000902 ↗ A Study on the Management of Combination Anti-HIV Drug Therapy in HIV-Positive Children With Prior Treatment Completed National Institute of Allergy and Infectious Diseases (NIAID) Phase 1 1969-12-31 The purpose of this study is to determine the value of changing anti-HIV medications in children with progressive HIV disease who have received previous treatment. Plasma viral load (the level of HIV in the blood) is probably most effectively reduced by giving patients anti-HIV drugs which affect the virus at various stages of development. Changing the medications may enhance the results of treatment.
NCT00001083 ↗ Comparison of New Anti-HIV Drug Combinations in HIV-Infected Children Who Have Taken Anti-HIV Drugs Completed National Institute of Allergy and Infectious Diseases (NIAID) Phase 2 1969-12-31 For PRAM-1: To evaluate zidovudine (ZDV) + lamivudine (3TC) vs. stavudine (d4T) + ritonavir vs. ZDV + 3TC + ritonavir with respect to the change in plasma HIV-1 RNA copy number from baseline to 48 weeks [AS PER AMENDMENT 1/5/98: 72 weeks; AS PER AMENDMENT 7/17/98: 48 weeks] in stable HIV-infected children with >= 16 weeks of prior continuous antiretroviral therapy. To evaluate the safety and tolerance of ZDV + 3TC vs. d4T + ritonavir vs. ZDV + 3TC + ritonavir based upon laboratory and clinical toxicities. AS PER AMENDMENT 10/20/97: For PRAM-1, Step 2: To evaluate d4T + nevirapine + ritonavir with respect to change in plasma HIV-1 RNA copy number from baseline to 48 weeks in children who have received at least 12 weeks of therapy on the PRAM-1 ZDV/3TC arm and have over 10,000 viral copies at weeks 12, 24, or 36. To evaluate the safety and tolerance of d4T + nevirapine + ritonavir based upon laboratory and clinical toxicities. [AS PER AMENDMENT 10/23/98: To evaluate safety and tolerance of a switch from d4T + ritonavir vs. ZDV + 3TC + ritonavir to d4T + indinavir vs. ZDV + 3TC + indinavir in stable, HIV-infected children with RNA values <= 10,000 copies/ml.] For PRAM-1: Evidence supports combination therapy with 2 or more antiviral agents as beneficial in the long-term management of HIV. The possibility exists that combination therapy may result in a synergistic or additive activity over a prolonged period of time. Also hypothesized is that the development of resistance to individual agents will be developed if viral replication is significantly decreased. AS PER AMENDMENT 10/20/97: For PRAM-1, Step 2: Interim analysis at 12 weeks on PRAM-1 indicates that the proportion of children reaching undetectable RNA levels on the ZDV + 3TC arm is significantly less than the other two arms. The protocol, therefore, has been modified (Step 2) to permit children in the ZDV + 3TC arm with RNA copy number >= 10,000 the opportunity to change to a novel therapeutic regimen (d4T + nevirapine + ritonavir).
