IGA score is given based on the investigator's assessment of the participant's plaque psoriasis at a given time point. Overall lesions are graded for induration, erythema, and scaling. The participant's plaque psoriasis is assessed as: cleared (0), minimal (1), mild (2), moderate (3), or severe (4).

PASI is a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. In this system, the body is divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these areas is assessed and scored separately for erythema, induration, and scaling, which are each rated on a scale of 0 (none) to 4 (severe) and extent of involvement on a scale of 0 (indicates no involvement) to 6 (90% to 100% involvement). The PASI produces a numeric score that can range from 0 to 72. A higher score indicates more severe disease. A PASI 90 response represents participants achieving at least a 90 percent improvement from baseline in the PASI score.

Percentage of participants achieving an IGA score of 0 or 1 and \>=2 grade improvement from baseline at Week 16 will be reported. 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).

Percentage of participants who achieve an IGA score of 0 or 1 and \>=2-Grade improvement from baseline to Week 16 will be reported. 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).

Percentage of participants who achieve an IGA score of 0 or 1 and \>=2 grade improvement from baseline at Week 16 will be reported. 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).

IGA assesses participant's plaque psoriasis.Lesions were graded for induration,erythema and scaling, each using 5 point scale.Induration: 0=no evidence of plaque elevation,1=minimal plaque elevation,=0.25 millimeters(mm);2=mild plaque elevation,=0.5mm;3=moderate plaque elevation,=0.75 mm; 4=severe plaque elevation, greater than(\>)1 mm; Erythema:0=no evidence of erythema, hyperpigmentation may be present,1=faint erythema,2=light red coloration,3=moderate red coloration,4=bright red coloration; Scaling:0=no evidence of scaling, 1=minimal; occasional fine scale over \<5% of lesion, 2=mild; fine scale dominates,3=moderate; coarse scale predominates, 4=severe; thick, scale predominates. Final IGA score of psoriasis was based upon average of induration, erythema and scaling scores assessed on a 5 point scale:cleared(0),minimal(1), mild(2),moderate(3),or severe(4). Higher score=more severe disease. Baseline:closest measurement taken prior to or at time of first study drug administration date.

Percentage of participants who achieved PASI 90 (at least 90% improvement from baseline in PASI score) response at Week 16 were reported. The PASI was a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. In the PASI system, the body was divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these areas were assessed and scored separately for erythema, induration, and scaling, which were each rated on a scale of 0 to 4 (0=none, 1 = slight, 2 = moderate, 3 = severe and 4 = very severe) and extent of involvement from 0 (indicated no involvement) to 6 (90% - 100% involvement). The PASI produced a numeric total score that could range from 0 (no psoriasis) to 72 (maximum psoriasis). Higher score indicated greater severity of psoriasis. The baseline was defined as the closest measurement taken prior to or at the time of the first study drug administration date.

Percentage of participants who achieved PASI-75 score (greater than or equal to \[\>=\] 75% improvement from baseline in PASI) at Week 16 were reported. The PASI was a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. In the PASI system, the body was divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these areas were assessed and scored separately for erythema, induration, and scaling, which were each rated on a scale of 0 to 4 (0=none, 1 = slight, 2 = moderate, 3 = severe and 4 = very severe) and extent of involvement from 0 (indicated no involvement) to 6 (90% - 100% involvement). The PASI produced a numeric total score that could range from 0 (no psoriasis) to 72 (maximum psoriasis). Higher score indicated greater severity of psoriasis. The baseline was defined as the closest measurement taken prior to or at the time of the first study drug administration date.

Percentage of participants who achieved \>=75% improvement from baseline in PASI score at LTE Week 36 was reported. The PASI was a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. In the PASI system, the body was divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these areas were assessed and scored separately for erythema, induration, and scaling, which were each rated on a scale of 0 to 4 (0=none, 1=slight, 2=moderate, 3=severe, 4=very severe) and extent of involvement from 0 (no involvement) to 6 (90% - 100% involvement). The PASI produced a numeric total score that could range from 0 (no psoriasis) to 72 (maximum psoriasis). Higher score indicated more severe disease. The baseline was defined as the closest measurement taken prior to or at the time of first study drug administration date in 77242113PSO2001 study.

Percentage of participants who achieved PASI-75 score (greater than or equal to \[\>=\] 75% improvement from baseline in PASI) at Week 16 was reported.
