A Phase 3, Multicenter, Randomized, Double-blind, Placebo-controlled Study Evaluating the Efficacy and Safety of CNTO 1959 (Guselkumab) in the Treatment of Subjects With Moderate to Severe Plaque-type Psoriasis

The purpose of this study is to demonstrate the superiority of CNTO 1959 (guselkumab) to placebo in the treatment of participants with moderate to severe plaque-type psoriasis (A common genetically determined, chronic, inflammatory skin disease characterized by rounded erythematous, dry, scaling patches).

Study Overview

• Status: Completed
• Conditions: Psoriasis
• Intervention / Treatment: Drug: CNTO 1959 50 mg; Drug: Placebo 100 mg; Drug: CTNO 1959 100 mg; Drug: Placebo 50 mg

Detailed Description

A Phase 3, multicenter (when more than one hospital or medical school team work on a medical research study), randomized (study drug assigned by chance), double-blind (neither the Investigator nor the participant know about the study treatment), placebo-controlled (a pretend treatment [with no drug in it] that is compared in a clinical trial with a drug to test if the drug has a real effect) study of CNTO 1959 (Guselkumab) in the treatment of participants with moderate to severe plaque-type psoriasis. Participants will receive either treatment of CNTO 1959 (guselkumab) 50 milligram (mg) or 100 mg or Placebo 50 mg or 100 mg. Participants will primarily be assessed for Investigator's Global Assessment (IGA) Score and Psoriasis Area and Severity Index (PASI). Participants' safety will be monitored throughout the study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With an Investigator's Global Assessment (IGA) Score of Cleared (0) or Minimal (1) at Week 16	The IGA documents the investigator's assessment of the participants psoriasis at a given time point. Overall lesions are graded for induration, erythema, and scaling. The participants' psoriasis was assessed as cleared (0), minimal (1), mild (2), moderate (3), or severe (4).	Week 16
Percentage of Participants Who Achieved a Psoriasis Area and Severity Index (PASI) 90 Response at Week 16	The PASI is a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. In the PASI system, the body is divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these areas is assessed separately for the percentage of the area involved, which translates to a numeric score that ranges from 0 (indicates no involvement) to 6 (90 percentage (%)-100% involvement), and for erythema, induration and scaling, which are each rated on a scale of 0 to 4. The PASI produces a numeric score that could range from 0 (no psoriasis) to 72. PASI 90 response was defined as at least a 90% reduction in PASI relative to Baseline.	Week 16

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame

Change From Baseline in the Dermatology Life Quality Index (DLQI) Total Score at Week 16	The DLQI is a 10-item questionnaire that measures the impact of skin disease on participant's quality of life. Each question was evaluated on a 4-point scale ranging from 0 (not at all) to 3 (very much); where higher scores indicate more impact on quality of life. The DLQI total score ranges from 0 (not at all) to 30 (very much): 0-1 = no effect at all on the participant's life; 2-6 = small effect on the participant's life; 7-12 = moderate effect on the participant's life; 13-18 = very large effect on the participant's life; 19-30 = extremely large effect on the participant's life.

Summations of item scores of the same subscale give the subscale scores, which are transformed into a range from 0 to 100; zero= worst HRQL, 100=best HRQL. Higher scores indicate better health status.	Baseline and Weeks 28, 48
Change From Baseline in Work Productivity and Activity Impairment (WPAI) Questionnaire Scores at Week 16	Changes from baseline in the 4 types (absenteeism, activity impairment, presenteeism, and Work productivity loss) of WPAI scores at Week 16 were evaluated. The WPAI questionnaire is used to measure productivity loss associated with psoriasis during the past 7 days. It consists of six questions about absence from work because of psoriasis, hours actually worked, reduction in productivity at work attributed to psoriasis and reduction in productivity while performing daily activities. Four separate overall scores were calculated, including absenteeism (work time missed due to health), presenteeism (impairment at work due to health), work productivity loss (overall work impairment due to health), and activity impairment due to health. Each score ranges from 0 to 100 with higher scores indicating greater impairment and less productivity.	Baseline and Week 16

Percentage of Participants Who Achieved Health Assessment Questionnaire-Disability Index (HAQ-DI) Response at Weeks 4, 8 and 16	HAQ-DI response was defined as change of less than or equal to (<=) -0.3 from baseline in HAQ-DI score. HAQ-DI is a 20-question instrument that assesses the degree of difficulty a person has in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and activities of daily living). Responses in each functional area are scored from 0, indicating no difficulty, to 3, indicating inability to perform a task in that area (that is, lower scores are indicative of better functioning).
