Brodalumab Drug-Drug Interaction (DDI) and Intensive Pharmacodynamic (PK) Study in Psoriasis Subjects

April 7, 2017 updated by: Bausch Health Americas, Inc.

An Open-label Study to Evaluate the Effect of Brodalumab on the Pharmacokinetics of Midazolam and Assess Single-Dose Brodalumab Pharmacokinetics in Subjects With Moderate to Severe Plaque Psoriasis

This is a phase 1, multi-center, open-label, drug-drug interaction (DDI) and PK study in subjects with moderate to severe plaque psoriasis. It is designed to evaluate the effect of brodalumab on midazolam PK in addition to assessing single dose PK of brodalumab in subjects with moderate to severe plaque psoriasis.
