Subjects received GUS 100 milligram (mg) administered as 100 mg per milliliter (mg/mL) solution subcutaneously (SC) at Weeks 0, 4, then every 8 weeks (at Week 12 and 20 - Part I). Subjects who completed Part I continued to receive GUS 100 mg at Week 28 and 32 - Part IIa. At Week 32, PASI 75 response was evaluated. PASI 75 responders and non-responders of GUS arm continued to receive GUS 100 mg SC every 8 weeks (weeks 36, 44 and 52). PASI 75 non-responders of FAE switched to 100 mg GUS SC at Week 32, continued at Week 36, 44 and 52. Safety follow-up was done at Week 32 (Part I), Week 64 (Part II) and up to 12 weeks after discontinuing drug. Subjects who received GUS in Part II (who started GUS at Week 0/ switched from FAE to GUS at Week 32), had no psoriatic arthritis at baseline and achieved PASI 90 response at end of Part II (Week 56), entered follow-up extension at Week 64 in Part III and were followed-up until loss of response/ until Week 100. | |||||||||||||||||||||||||||

The doses were up-titrated and had to be taken every day with different daily doses depending on the optimal individual benefit risk ratio (maximum 6*120 mg/day) according to local prescribing information up to Week 24. Subjects who completed the treatment phase until Week 24 entered the Part II of the study. Subjects who completed Part I and consented for Part IIa continued to receive commercially available FAE tablets specifically labeled for the study from Week 24 through Week 32 during study Part IIa. For subjects who discontinued study, a safety follow-up was done at Week 32 (Part I) or 12 weeks after last treatment (whatever came first). For all subjects who continued study, safety was followed-up at every visit.

Part I: Percentage of Subjects who Achieved Psoriasis Area and Severity Index (PASI) 90 Response at Week 24 | ||||||||||||
End point description |
PASI is system used for assessing and grading severity of psoriatic lesions and their response to therapy. In PASI system, body is divided into 4 regions: head, trunk, upper extremities, lower extremities. Each area is assessed separately for percentage of area involved, which translates to numeric score from 0 (indicates no involvement) to 6 (90 percent [%] to 100% involvement), and for erythema, induration, and scaling, each rated on scale of 0 (none) to 4 (severe). PASI produces score range from 0 (no visible skin involvement) to 72 (maximal skin involvement of whole body). Higher score indicates more severe disease. PASI 90 response denotes subjects achieving 90% improvement from baseline in PASI score. Efficacy analysis set (EAS) included all subjects randomized to 1 of 2 treatments (GUS or FAE) at Week 0 regardless of treatment they received. Missing data was imputed by non-responder imputation (NRI) (subjects with missing data at Week 4,16 and 24 were non-responders).

Part IIb: Percentage of Subjects with a PASI 90 Response at Week 32 who Maintained Response at Week 56 | ||||||||||||
End point description |
PASI is system used for assessing and grading severity of psoriatic lesions and their response to therapy. In PASI system, body is divided into 4 regions: head, trunk, upper extremities, lower extremities. Each area is assessed separately for percentage of area involved, which translates to numeric score from 0 (indicates no involvement) to 6 (90 percent [%] to 100% involvement), and for erythema, induration, and scaling, each rated on scale of 0 (none) to 4 (severe). PASI produces numeric score range from 0 (no visible skin involvement) to 72 (maximal skin involvement of whole body). Higher score indicates more severe disease. PASI 90 response denotes subjects achieving 90% improvement from baseline in PASI score. Part IIb analysis set included all subjects who entered Part IIb and treated with 1 of 2 treatments (GUS or FAE) during treatment period from Week 32 to 56. Missing data imputed using NRI (subjects with missing data at Week 40, 48, and 56 considered non-responders).

End point description |
DLQI is 10-item questionnaire that measures impact of skin disease on subject's quality of life, used to assess 6 different aspects that may affect quality of life 1) symptoms and feelings, 2) daily activities, 3) leisure, 4) work/school performance, 5) personal relationships, 6) treatment. Each question was evaluated on 4-point scale ranging from 0 (not at all) to 3 (very much); higher scores indicate more impact on quality of life. DLQI produces total numeric score ranging from 0 (not at all) to 30 (very much): 0-1=no effect at all on subject's life; 2-6=small effect 7-12=moderate effect; 13-18 =very large effect; 19-30 =extremely large effect. Higher score indicates low quality of life due to more severe disease. Part IIb analysis set included all subjects who entered Part IIb and treated with 1 of 2 treatments (GUS or FAE) from Week 32 to 56. Missing data imputed by NRI (subjects missing data at Week 40,48 and 56 were considered non-responders).

End point description |
PSSD (7-day version) is patient-reported outcome (PRO) questionnaire designed and validated to measure severity of psoriasis symptoms and signs for assessment of treatment benefit. It consisted of 11 items covering symptoms (itch, pain, stinging, burning, and skin tightness) and patient-observable signs (skin dryness, cracking, scaling, shedding or flaking, redness, and bleeding) using 0 (absent) to 10 (worst imaginable) numerical rating scales for severity. Items were averaged on daily symptom score and sign score when at least 3 items >= 50 percentage of 5 items on these scales are answered. The average value is converted into 0-100 scoring, such that Symptom [or Sign] score=average value*10, where, 0= least severe and 100=most severe and higher score indicates more severe disease. Part III analysis set included all subjects who were treated with guselkumab during Part IIb (Weeks 32 to 64) and entered Part III. Missing data was imputed using LOCF imputation method.

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 subject'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. Study Part III analysis set included all subjects who were treated with guselkumab during Part IIb (Weeks 32 to 64) and entered Part III. Missing data was imputed using LOCF imputation method.

Part III: Change From Baseline (week 56) in 36-Item Short-Form Health Survey Version 2 (SF-36 V2) Physical Component Summary (PCS) and Mental Component Summary (MCS) Scores at Week 100 | ||||||||||||||||||||||||
End point description |
SF-36 V2 is generic 36-item questionnaire measuring health-related quality of life (HRQL) covering 2 summary measures: PCS and MCS. SF-36 consists of 8 subscales (physical function, role limitations due to physical problems, pain, general health perception, vitality, social function, role limitations due to emotional problems, and mental health). Subjects self-report on items in a subscale that have between 2-6 choices per item using Likert-type responses (e.g. none of time, some of time, etc.). Summations of item scores of same subscale give subscale scores, which are transformed into a range from 0 to 100; zero= worst HRQL, 100=best HRQL. Higher scores indicate better health status. Part III analysis set included all subjects who were treated with guselkumab during Part IIb (Weeks 32 to 64) and entered Part III. Missing data was imputed using LOCF method.
