Evaluation of Systemic Bioavailability and Effects on 24-Hour Plasma Cortisol Profile of 6 mg Delivered Once Daily Versus 3 mg Delivered Twice Daily in Healthy Adult Male Volunteers

Summary

Single-centre, randomized, double-blind, two-period, two-sequence, cross-over 7-day study.

This study is the first safety/tolerability evaluation of a product -suppository formulation containing 6 mg BDP (once daily dosing), a second-generation oral or rectal corticosteroids with high topical anti-inflammatory efficacy in the gut and minimal systemic bioavailability (BA).

BDP is marketed in different pharmaceutical formulations, including 3 mg suppositories, and approved for ulcerative proctosigmoiditis in the first attack or exacerbation phase at the dosage of 3 mg twice a day. For these reasons, a 6 mg suppository (Test - "T" product) is a scale-up of the 3 mg formulation (Reference - "R" product).

For locally-applied-locally acting drug products that result in quantifiable systemic availability due to absorption from the administration site, relative systemic BA is informative for safety, but also with respect to efficacy. Therefore, safety/tolerability of T is evaluated through a comparison to R.
