Psoriasis Clinical Trial

Adrenal Suppression and Absorption Study of Halobetasol Propionate Foam in Subjects 12-17 With Plaque Psoriasis

Summary

The purpose of this study is to evaluate Halobetasol Propionate (HBP) foam, 0.05% in subjects aged 12 through less than 18 years with plaque psoriasis in order to check the safety, the potential to suppress the adrenal glands and the degree to which the drug is absorbed into the bloodstream.

Full Description

This is a Phase 4 (for US site only, Phase 2 for non-US sites), open label, multicenter study of halobetasol propionate (HBP) Foam, 0.05% in male and female subjects who are 12 to less than 18 years of age with stable plaque psoriasis. Twenty-four subjects with stable plaque psoriasis on at least 10% of their body surface area (BSA) (excluding the face, scalp, groin, axillae, and other intertriginous areas), who fulfill the inclusion/exclusion criteria will be enrolled at multiple study sites in the US and Europe. All subjects are to have a Cosyntropin Stimulation Test (CST) to assess their (hypothalmic pituitary adrenal) HPA axis response at Visit 1/Screening initiated between 7 and 9 AM. Enrollment into the treatment phase of the study will be timed such that the Screening CST is performed a minimum of 20 days before Visit 2/Baseline. At Visit 2/Baseline, eligible subjects with normal adrenal function will be eligible to participate in the study.

The primary objective of the study is to assess safety, not efficacy. Safety will be determined by assessing the adrenal suppression potential and the PK properties of HBP Foam, 0.05% applied twice daily in male and female subjects who were 12 to less than 18 years of age with stable plaque psoriasis.

Other safety endpoints include plasma levels of HBP. Trough HBP concentrations in plasma on day 8 and 15 will be calculated and summarized. Efficacy will also be noted utilizing the Investigator's Global Assessment (IGA) scale and percent BSA treated and affected with disease to assess and document any changes observed with regard to IGA and percent BSA.
