Trial Outcomes & Findings for Efficacy and Safety Study of Guselkumab in the Treatment of Participants With Moderate to Severe Plaque-Type Psoriasis (NCT NCT02905331)

NCT ID: NCT02905331

Last Updated: 2025-02-04

Results Overview

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 participant's psoriasis is assessed as cleared (0), minimal (1), mild (2), moderate (3), or severe (4). Participants who achieved an IGA score of cleared (0) or minimal (1) were considered IGA cleared or minimal responders. Non-responder imputation (counted as non-responders) was applied for participants who met treatment failure rules, as well as for remaining missing data after treatment failure. Participants who discontinued study drug due to lack of efficacy, an adverse event (AE) of worsening of psoriasis, or who started a protocol-prohibited medication/therapy during study that could improve psoriasis were considered as treatment failures for the study.

PRIMARY outcome

Timeframe: Week 16

Population: Full analysis set (FAS) included all randomized participants who received at least 1 injection of study drug. Participants were analyzed according to the assigned treatment to which they were randomized, regardless of the treatment they actually received.

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 participant's psoriasis is assessed as cleared (0), minimal (1), mild (2), moderate (3), or severe (4). Participants who achieved an IGA score of cleared (0) or minimal (1) were considered IGA cleared or minimal responders. Non-responder imputation (counted as non-responders) was applied for participants who met treatment failure rules, as well as for remaining missing data after treatment failure. Participants who discontinued study drug due to lack of efficacy, an adverse event (AE) of worsening of psoriasis, or who started a protocol-prohibited medication/therapy during study that could improve psoriasis were considered as treatment failures for the study.

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 percent (%) to 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 can range from 0 (no psoriasis) to 72. A higher score indicates more severe disease. A PASI 90 response represents participants who achieved at least a 90 percent improvement from baseline in the PASI score. Non-responder imputation (counted as non-responders) was applied for participants who met treatment failure rules, as well as for remaining missing data after treatment failure.

The participant's psoriasis is assessed as cleared (0), minimal (1), mild (2), moderate (3), or severe (4). Participants who achieved an IGA score of cleared (0) or minimal (1) were considered IGA cleared or minimal responders while those achieved an IGA score of cleared (0), minimal (1), or mild (2) were considered IGA mild or better responders.

SECONDARY outcome

Timeframe: Week 4, 8, 12, 16, 20, 24, 28, 32, and Week 40 (4 weeks beyond the recommended q8w dosing interval)

Population: FAS included all randomized participants who received at least 1 injection of study drug. Here, n (number analyzed) signifies number of participants who were analyzed at specific timepoint, for each arm, respectively. Non-responder imputation was used to impute missing data.

PASI is a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. In PASI system, body is divided into 4 regions: 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% to 100% involvement), and for erythema, induration, and scaling, which are each rated on a scale of 0 to 4. PASI produces a numeric score that can range from 0 (no psoriasis) to 72.Participants with \>=50%, \>= 75%, \>=90% and \>= 100% improvement in PASI from baseline were considered PASI 50, 75, 90 and PASI 100 responders, respectively. Participants were analyzed according to the assigned treatment to which they were randomized, regardless of the treatment they actually received. From week 20, participants in placebo group, only included participants who crossed over to receive guselkumab at week 16.
