Conditions
Plaque Psoriasis
Interventions
Drug: FP187
Drug: Fumaderm® placebo
Drug: FP187 placebo
Registration Number
NCT01815723
Lead Sponsor
Forward-Pharma GmbH
Brief Summary

This multicenter, randomised, double-dummy, Fumaderm® and placebo-controlled, parallel-group study will compare the efficacy and safety of 500 mg of FP187 (250 mg twice daily) compared to 720 mg Fumaderm® (240 mg three times daily) over 20 weeks of treatment. After an initial wash-out non-drug treatment phase of 1 to 6 weeks, all patients will receive allocated Study treatment up-titrated to the relevant dose level (i.e., 500 mg daily FP187, 720 mg daily Fumaderm®, or placebo). The up-titration to full dose will last 4 weeks for FP187 and 9 weeks for Fumaderm®. After 20 weeks of treatment, all patients will be asked to enter a separate open label treatment protocol expected to continue for up to 5 years.
