Group 2a and Group 2b: Percentage of Participants Who Achieved an Absolute Psoriasis Area and Severity Index (PASI) Score Less Than (<) 3 at Week 68 |
Percentage of participants who achieved an absolute PASI <3 at Week 68 were reported. 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 body surface area involved, which translates to a numeric score that ranged from 0 (indicated 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 (maximum psoriasis). Higher score indicated greater severity of psoriasis. |

Group 1, Group 2a, Group 2b and Group 2c: Relationship Between Trough Serum Concentration and Efficacy or Serum Biomarker Level |
The potential association between trough serum guselkumab concentration and efficacy or serum biomarker level will be analyzed by immunoassays. For the analyses the trough serum guselkumab concentration will be set into relation with the efficacy (e.g. PASI response) or with serum biomarker (e.g. serum IL-17A, IL-17F, IL-22) concentration. Guselkumab and all biomarker concentrations will be measured in the unit of picogram/milliliter (pg/mL). 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%-100% involvement), and for erythema, induration, and scaling, which are each rated on a scale of 0 to 4.

An adverse event (AE) is any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non-investigational) product, whether or not related to that medicinal (investigational or non-investigational) product. |
