Clinical Trial Summary

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).

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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
Primary	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	Percentage of Participants Who Achieved PASI 75 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 75 response was defined as at least a 75% reduction in PASI relative to Baseline.	Week 16
Secondary	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.

Secondary	Change From Baseline in Body Surface Area (BSA) Involvement by Psoriatic Lesions at Week 48	BSA as physical measure to define disease severity is to determine how much of the Body Surface Area (BSA) is affected by psoriasis. Involved BSA is calculated by using the palm of the participant's hand as equivalent to 1% of the BSA (rule of palm). Psoriasis affected BSA under 5% suggests mild psoriasis, a BSA of 5% to 10% is considered moderate, and an involved BSA of over 10% indicates severe psoriasis.	Baseline and Week 48

Secondary	Change From Baseline in the Tender Joints Count and Swollen Joints Count at Weeks 4, 8, and 16	Change from baseline in the tender joints and swollen joints counts at Weeks 4, 8, and 16 was evaluated.	Baseline and Weeks 4, 8, 16
Secondary	Change From Baseline in the Tender Joints Count and Swollen Joints Count at Weeks 28, 36, 48, and 52	Change from baseline in the tender joints and swollen joints counts at Weeks 28, 36, 48 and 52 was evaluated.	Baseline and Weeks 28, 36, 48, 52
Secondary	Percent Change From Baseline in Patient's Assessment of Pain (VAS) at Weeks 4, 8, 16	Percent change from baseline in Patient's Assessment of Pain (VAS) among participants who had a diagnosis of PsA at screening at Weeks 4, 8 and 16 was evaluated. Each participant assessed his/her pain associated with joint symptoms on each assessment day using a 100 mm VAS ranging from 0 millimeter (mm) (no pain) to 100 mm (the worst pain imaginable).	Baseline and Weeks 4, 8, 16

Each participant assessed his/her pain associated with joint symptoms on each assessment day using a 100 mm VAS ranging from 0 mm (no pain) to 100 mm (the worst pain imaginable).	Baseline and Weeks 28, 36, 48, 52
Secondary	Percent Change From Baseline in Patient's Global Assessment of Disease Activity at Weeks 4, 8, 16	The participant's and physician's global assessments of disease activity were recorded on a VAS. The VAS for the participant's assessment ranges from "very well" (0 centimeter [cm]) to "very poor" (10 cm).	Baseline and Weeks 4, 8, 16
Secondary	Percent Change From Baseline in Patient's Global Assessment of Disease Activity at Weeks 28, 36, 48, and 52	The participant's and physician's global assessments of disease activity were recorded on a VAS.

Secondary	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).
