Descriptive Information
Brief Title  ICMJE A Study Comparing Two Forms of Didanosine in HIV-infected Patients
Official Title  ICMJE Pivotal Bioequivalence Study of Videx Chewable/Dispersible Buffered Tablets and an Encapsulated Enteric Coated Bead Formulation of Didanosine in HIV-Infected Subjects
Brief Summary

The purpose of this study is to see if the coated-capsule form of didanosine (ddI) is as safe and absorbed by the body as well as the chewable-tablet form of ddI.

Didanosine (ddI) is an anti-HIV drug. The effectiveness of ddI can be lowered by acid in the stomach. To prevent this, patients take antacids with ddI. The coated-capsule form of ddI may replace the need for antacids.

Detailed Description

Didanosine, a purine nucleoside analogue, is indicated for the treatment of HIV infection when antiretroviral therapy is warranted. Didanosine is administered orally with antacids to protect it against acid-induced hydrolysis in the stomach. To eliminate the need for using buffers in the ddI formulations, an enteric-coated bead formulation of ddI is being developed.

Patients are randomized to 1 of 2 groups to receive treatment on 2 separate occasions at least 72 hours apart. Group 1 receives the reference formulation of ddI. Group 2 receives the test formulation of ddI. Clinical evaluations, including clinical laboratory tests, are performed periodically during the study and at discharge. Serial blood samples are collected at specific time points over the 12 hours following dosing, and are used for the pharmacokinetic variables CMAX and AUC(INF). Factors used in analysis are sequence, subject within sequence, period, and formulation. Safety is assessed by monitoring adverse effects, vital signs, ECG recordings, and clinical laboratory tests throughout the study.
