History of Changes
This pilot pharmacokinetic study is designed to exclude a large difference (>40%) in
pharmacokinetics (esp. AUC) between two new Lopimune formulations and the branded
formulation. The formal bioequivalence study with adequate power will be conducted by the
manufacturer. In order to get data independently from the manufacturer and to have this
information in an earlier phase, this small pilot study is initiated.
The initial study showed a declined bioavailability of the granules under fasting conditions. The study has been extended with an arm determining the pharmacokinetics of the granules after food (compared to the oral solution taken with food).
Drug : Lopinavir/ritonavir
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

|Study Start Date:||September 2008|
|Study Completion Date:||February 2009|
|Primary Completion Date:||February 2009 (Final data collection date for primary outcome measure)|
Lopinavir/ritonavir 200/50mg; 2 tablets; single dose
Other Name: Kaletra
Lopinavir/ritonavir 100/25mg; 4 sachets with granules; single dose
Other Name: Lopimune granules
Lopinavir/ritonavir 100/25mg; 4 tablets; single dose
Other Name: Lopimune tablets
Cipla has developed two co-formulated forms of lopinavir/ritonavir for second-line
antiretroviral therapy for children: Lopimune granules and Lopimune tablets. They contain
100mg lopinavir and 25mg ritonavir.
Primary objective of this study:
To determine the pharmacokinetic profile of lopinavir and ritonavir in two different co-formulations (Lopimune granules and Lopimune tablets) after single-dose in HIV-negative, healthy adult subjects, and to compare this to the branded product.
To evaluate the safety of single-dose administration of the two generic co-formulations of lopinavir/ritonavir and compare this to the branded product.
