General information about the trial
|
|||
Main objective of the trial |
The primary objective of the study is to characterize the single-dose and steady- state pharmacokinetics (PK) of diacerein and its active metabolite, rhein, after topical application of CCP-020 (diacerein 1% ointment) under maximum use conditions in adult, adolescent and in infants/children with EB.

Detectable Plasma Concentrations of Diacerein and Rhein [1] | |||||||||||||||||||||||||||||||||
End point description |
Bioanalytical analyses were performed to determine concentrations levels of diacerein and rhein in plasma using validated bioanalytical methods. For Cohort 1, blood samples were taken at pre-dose and 0.5, 1, 2, 3, 4, 6, and 8 hours post-dose. For Cohort 2, blood samples were taken at pre-dose and 1, 2, 4, 6, and 8 hours post-dose. Trough PK samples were collected on any 2 available days from Days 3 through 9 for Cohort 1 only. Summary statistics for each scheduled time were only reported if at least 50% of subjects hand quantifiable concentrations.
