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

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.
