Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

To determine the relative antiviral activity and safety of zidovudine ( AZT ) and didanosine ( ddI ) alone and in combination, as well as in various sequences of administration. The relative efficacy of the approved antiretrovirals in early HIV-1 disease is unclear; thus, a study is needed to evaluate the ability of these various nucleoside analogs to limit pathogenicity.
