Pharmacokinetics and Safety Study of Tipranavir in Combination With Low Dose Ritonavir in Human Immunodeficiency Virus (HIV)-Infected Children

Phase 1
Completed
Conditions
HIV Infections
Interventions
Drug: TPV oral solution
Registration Number
NCT00076999
Lead Sponsor
Boehringer Ingelheim
Brief Summary

The primary objective of this study is to assess the safety and tolerability of tipranavir (TPV) oral formulation and soft gelatin capsules together with low-dose ritonavir in HIV-infected children and adolescents, to provide information concerning the pharmacokinetic characteristics of tipranavir and ritonavir in this age group, and to determine the relative bioavailability of the TPV liquid formulation and TPV capsule formulation in adolescents switching from liquid to capsule.

The secondary objective of this study is the determination of the dose of topranavir and ritonavir (TPV/r) in children and adolescents between 2 and 18 years of age required for an adult equivalent systemic exposure of TPV/r 500 mg / 200 mg.

Primary Outcome Measures
NameTimeMethod
Number of Patients With Severe (DAIDS Grades 3 or 4) Laboratory Abnormalities by Age Group and Formulationup to 288 weeks

Intensity of adverse events were graded by the investigator based on the DAIDS standardized table (Division of AIDS, National Institute of Health). DAIDS Grade 3 (Severe) and Grade 4 (Life Threatening) were identified.
