To Evaluate the Pharmacokinetic of Diacerein and Rhein After Maximum Use in Patients With Epidermolysis Bullosa (EB)

Dystrophic Epidermolysis Bullosa Clinical Trial

Official title:
A Multi-Center Study to Evaluate the Pharmacokinetics of Diacerein and Rhein and the Safety of Diacerein After Maximum Use, Topical Administration of CCP-020 (Diacerein 1% Ointment) to Patients With Epidermolysis Bullosa (EB)

Clinical Trial Summary

A pharmacokinetic (PK) study in 16-20 EB subjects to be allocated to two cohorts. Cohort 1 to include 8-10 subjects (ages 12 yrs and older); Cohort 2 to include 8-10 subjects (ages 6 months-11 yrs, inclusive). Cohort 2 only included subjects 4 yrs and older. Serial PK blood sampling collected on Days 1 and 10. Analyses were performed to determine the concentrations of diacerein and rhein.

Clinical Trial Description

This was an open-label, single-period study that intended to include subjects with EB consisting of infants/ children (ages 6 months to 11 years, inclusive) and adolescents/ adults (ages 12 years and older). The study included 2 cohorts.

Cohort 1 was to include adolescent/adult subjects with EB (ages 12 years and older);

Cohort 2 was to include infants/children with EB (ages 4 to 11 years, inclusive).

For both cohorts, the study intended to enroll subjects with epidermolysis bullosa simplex (EBS), dystrophic epidermolysis bullosa (DEB), and junctional epidermolysis bullosa (JEB) with lesions encompassing >/=2% BSA. The diacerein application area was >/=5% BSA and included lesioned and non-lesioned skin (if lesions accounted for <5% BSA); however, topical administration was </=30% BSA. On Days 1 and 10, the topical dose of study drug was applied by study staff, and blood was sampled for PK analyses of diacerein and rhein pre-dose and through 8 hours post-application. On Days 2 to 9, study drug was applied to the application area(s) at home. For Cohort 1, trough PK samples were collected on any 2 available days from Days 3 through 9, and study drug was applied after blood draw, while for Cohort 2 trough PK analyses were not performed. ;
