Clinical Trial: A Comparison of Zidovudine Plus Lamivudine Versus ddI Used Alone or in Combination with Zidovudine in HIV-1 Infected Children

This study has been completed.

Sponsors and Collaborators: National Institute of Allergy and Infectious Diseases (NIAID)
Bristol-Myers Squibb
Glaxo Wellcome
Information provided by: National Institute of Allergy and Infectious Diseases (NIAID)


To compare the efficacy of lamivudine (3TC) and zidovudine (AZT) in combination versus the better of didanosine (ddI) monotherapy or ddI/AZT combination, in symptomatic HIV-1 infected children who received less than 56 days of prior antiretroviral therapy. To evaluate the safety and tolerance of 3TC/AZT in this patient population. To determine other measures of diseases in response to the study regimens. Currently, none of the potential treatments for HIV-1 infection has proven to be both nontoxic and effective in long-term use. However, previous studies in both adults and children have shown that 3TC combined with AZT reduced HIV load in blood and increased white blood cells. Additionally, 3TC has demonstrated a favorable safety profile.

Official Title: A Randomized Comparative Study of Combined Zidovudine-Lamivudine (3TC) vs. the Better of ddI Monotherapy vs. Zidovudine Plus ddl in Symptomatic HIV-1 Infected Children

Further Study Details: 

Expected Total Enrollment:  740

Currently, none of the potential treatments for HIV-1 infection has proven to be both nontoxic and effective in long-term use. However, previous studies in both adults and children have shown that 3TC combined with AZT reduced HIV load in blood and increased white blood cells. Additionally, 3TC has demonstrated a favorable safety profile.

Patients are randomized to receive oral 3TC/AZT, ddI/AZT, or ddI alone for at least 24 months. PER AMENDMENT 4/29/96: NOTE: Randomization to ZDV+ddI arm was terminated in Spring of 1996 based upon the results of ACTG 152. Patients on that arm will continue on blinded study drug and will be followed until the end of the study.
