Brief summary

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

To assess the safety and to evaluate the anti-HIV effect of low-, moderate-, and high-dose schedules of zidovudine (AZT) plus didanosine (ddI) versus ddI alone in asymptomatic HIV-infected patients. Because of the failure with long-term (more than 1 year) use of, frequency of toxicity from, and drug resistance to AZT, drug combinations need to be developed to enable lower, less toxic doses of AZT to be used and to slow or prevent the development of resistance, while providing at least the same effectiveness.
