Conditions

Plaque Psoriasis

Brief summary

The goal of this Phase 3 clinical trial is to compare efficacy and safety of CT-P55 with Cosentyx in patients with moderate to severe plaque psoriasis

Detailed description

CT-P55 is a recombinant humanized monoclonal antibody containing the active ingredient secukinumab. CT-P55 is a drug product being developed by CELLTRION, Inc. and being compared to the EU-approved Cosentyx®. In this study, Efficacy and Safety of CT-P55 will be evaluated in patients with Moderate to Severe Chronic Plaque Psoriasis.

Interventions

Design outcomes

Primary

MeasureTime frameDescription
Percent change from baseline in Psoriasis Area and Severity Index (PASI) scoreWeek8A higher percent change indicates a better outcome. While the maximum value is 100%, the minimum value is not fixed and may be negative in cases of worsening symptoms.

Secondary

MeasureTime frameDescription
Actual PASI scoresUp to 56 WeeksMinimum 0 to Maximum 72 Higher scores mean a worse outcome
Percent change from baseline in PASI scoreUp to 56 WeeksA higher percent change indicates a better outcome. While the maximum value is 100%, the minimum value is not fixed and may be negative in cases of worsening symptoms.
Proportion of patients who achieve at least 50/75/90/100% improvement from baseline in PASI (PASI 50/75/90/100)Up to 56 Weeks
Proportion of patients with Investigator's Global Assessment (IGA) score of clear (0) or almost clear (1)Up to 56 Weeks
Change from baseline in Dermatology Life Quality Index (DLQI)Up to 56 WeeksMinimum -30 to Maximum of 30 Higher scores indicate a worse outcome
