CLINICAL TRIALS PROFILE FOR LAMIVUDINE, NEVIRAPINE AND ZIDOVUDINE

All Clinical Trials for LAMIVUDINE, NEVIRAPINE AND 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 the opportunity to change to a novel therapeutic regimen (d4T + nevirapine + ritonavir).
NCT00001085 ↗	A Study of 141W94 Used Alone or in Combination With Zidovudine Plus 3TC in HIV-Infected Patients	Completed	National Institute of Allergy and Infectious Diseases (NIAID)	Phase 2	1969-12-31	To determine the proportion of patients whose plasma HIV-1 RNA level remains below a detectable level (less than 500/ml) after 24 weeks of study therapy with either 141W94 monotherapy or 141W94 plus zidovudine (ZDV) and lamivudine (3TC). To determine the safety and tolerability of 141W94 monotherapy and the combination of 141W94 plus 3TC in patients with HIV infection. Although dramatic inhibition of HIV-1 replication is achieved with ritonavir or indinavir monotherapy, in both cases maximum suppression required combination treatment together with nucleoside analog RT inhibitors. This study tests the hypothesis that monotherapy with 141W94 doses that result in Cmin levels far in excess of the IC90 corrected for plasma protein binding for HIV-1 can achieve the same virologic and immunologic effects in terms of magnitude and durability, as has been observed with combinations of other protease inhibitors plus nucleoside analogs.
