Trial Outcomes & Findings for The Efficacy and Safety of Secukinumab in Patients With Ichthyoses (NCT NCT03041038)

NCT ID: NCT03041038

Last Updated: 2021-08-25

Results Overview

Primary Efficacy Endpoint. The IASI score was modelled after the Eczema Area and Severity Index (EASI) and Psoriasis Area and Severity Index (PASI), commonly used in clinical trials for atopic dermatitis and psoriasis, respectively. This scale measures erythema and scaling and has a range of 0-48 (sum of a max score of 24 for erythema and 24 for scaling). A higher score means worse clinical severity. Mean difference IASI total score at Baseline was compared to IASI total score at Week 16.
