Bioequivalence Study of Didanosine in Children Treated for HIV
PKPOP Study of Didanosine in HIV Treated Children, at Fasting Period and During the Meal
The purpose of this study is to show that the administration of 400/mg/m2/day of didanosine(ddI) during the meal is bioequivalent to the administration of 240/mg/m2/day of didanosine during fasting, in HIV infected children treated by a ARV combination including ddI
The didanosine is one of the reverse transcriptase inhibitors. This drug is efficient against the viral replication of the HIV. Licensing for the children was obtained in June, 1992. The main problem of the didanosine is its poor bioavailability: although gastro-resistant capsules were developed, its bioavailability remains dependent on alimentation. Taking a meal 1-2 hours before the administration of ddI leads to a reduction of 50% of its bioavailability as well for the child as for the adult. It is therefore recommended to take ddI during fasting period. This regimen in some cases can decrease therapeutic observance. A pharmacokinetic study of ddI will be conducted during the meal with 240 mg/m2/day during fasting period compare to 400 mg/m2/day during the meal. 26 patients, aged more than 6 years old, will be included and randomised in 2 groups. The first group will take the standard dose of ddI during 28 days during fasting period (phase A), then the high dose during the meal during 28 days (phase B). The second group will take first the phase B and secondly the phase A. Patients will be sequentially evaluated both after the first and the second period of treatment for pharmacokinetics and biological analysis.
