Trial Outcomes & Findings for Comparison of CHS-1420 Versus Humira in Subjects With Chronic Plaque Psoriasis (NCT NCT02489227)

NCT ID: NCT02489227

Last Updated: 2020-04-08

Results Overview

The efficacy success criterion was the equivalence between CHS-1420 and Humira at Week 12. Equivalence was based upon 2-sided 95% confidence interval (CI) for the difference between the proportions of subjects in the CHS-1420 and Humira groups achieving PASI-75 at Week 12. If the 95% CI lay entirely within the interval (-15%, 15%), equivalence was established.
