A Phase I Safety and Pharmacokinetics Study of 2',3'-Dideoxyinosine (ddI) Administered Twice Daily to Infants and Children With AIDS or Symptomatic HIV Infection

Summary

To determine the safety and maximum tolerated dose (MTD) of 2',3'-dideoxyinosine (ddI), given orally and intravenously, in infants and children with AIDS. The study also measures bloodstream and cerebrospinal fluid (CSF) levels of the administered drug, and provides a preliminary assessment of the effectiveness of ddI on HIV replication. AMENDED: Based on safety established in the first dosing phase of 52 weeks and long term dosing data in adults, the dosing period will be extended to 104 weeks. Original design: Information presently available indicates that ddI has high antiviral activity with less apparent toxicity than zidovudine (AZT) (the drug presently used to treat AIDS).
