Study Summary

To evaluate and compare the long-term (48-177 weeks) safety, tolerance, and efficacy of two doses of zalcitabine ( dideoxycytidine; ddC ) taken orally every 8 hours in children with symptomatic HIV infection who have one of the following: intolerance to zidovudine ( AZT ) (development of toxicity during prolonged AZT therapy), demonstrated disease progression after 6 months of AZT therapy, OR both AZT intolerance and disease progression after 6 months of AZT therapy. As useful as AZT appears to be in the treatment of patients infected with HIV, it is associated with significant toxicity in some patients, and it does not prevent ultimate progression to AIDS and eventual mortality. Thus, there is a clear need for new antiretroviral drugs, and ddC is one such promising agent.
