Brief summary

The purpose of this study is to evaluate the efficacy and safety of ustekinumab in pediatric participants aged greater than or equal to (\>=) 6 through less than (\<) 12 years with moderate to severe chronic plaque psoriasis

Detailed description

This is an open label (identity of study drug will be known to participant and study staff) and multicenter (when more than one hospital or medical school team work on a medical research study) study. The participant population will be comprised of boys and girls who have had a diagnosis of plaque psoriasis for at least 6 months prior to first study drug administration and who have moderate to severe disease defined by Psoriasis Area and Severity Index score (PASI) \>=12, Physician's Global Assessment (PGA) \>=3, and Body Surface Area (BSA) \>=10 percent (%). The study consists of Screening Phase (up to 10 weeks before administration of the study drug), Treatment Period (Week 0 up to Week 52) and Safety follow up (Week 56). Participants will be primarily evaluated for efficacy, pharmacokinetics (PK) and safety. Following completion of the Week 52 visit, participants who have had a beneficial response from ustekinumab treatment as determined by the investigator, and who have not yet reached the age of 12 years or older in countries where marketing authorization for ustekinumab has been granted for the treatment of psoriasis in adolescent participants (12-17 years), and are willing to continue ustekinumab treatment, may enter the long-term extension period (from Week 56 through Week 264) of the study.

Interventions

DRUGUstekinumab 0.75 mg/kg

Participants weighing less than (\<) 60 kilograms will receive ustekinumab 0.75 milligram per kilogram (mg/kg) at Weeks 0 and 4 followed by every 12 weeks dosing with the last dose at Week 40. Eligible participants for LTE period will continue to receive ustekinumab 0.75 mg/kg up to Week 248.

Participants weighing greater than or equal to (\>=) 60 kg to less than or equal to (\<=) 100 kg will receive ustekinumab 45 mg at Weeks 0 and 4 followed by every 12 weeks dosing with the last dose at Week 40. Eligible participants for LTE period will continue to receive ustekinumab 45 mg up to Week 248.

Participants weighing \>100 kg will receive ustekinumab 90 mg at Weeks 0 and 4 followed by every 12 weeks dosing with the last dose at Week 40. Eligible participants for LTE period will continue to receive ustekinumab 90 mg up to Week 248.

MeasureTime frameDescription
Percentage of Participants With Physician's Global Assessment (PGA) Score of Cleared (0) or Minimal (1) at Week 12Week 12The PGA is used to determine the participant's 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), marked (4), or severe (5). Higher scores indicate worse disease. Treatment Failure (TF) criteria- discontinued study agent due to lack of efficacy or adverse event of psoriasis or who started protocol-prohibited medication/therapy.

MeasureTime frameDescription
Change From Baseline in Children Dermatology Life Quality Index (CDLQI) Score at Week 12Baseline and Week 12CDLQI was used to assess the impact of psoriasis on subject health-related quality of life. The CDLQI has 10 items assessing health-related quality of life (HRQOL) in patients with skin disease each measured on a scale from 0 (Not at all) to 3 (Very much). The total score ranges from 0 to 30, with lower scores indicating better quality of life. The higher the score, the greater the impairment in quality of life (QoL).

Percentage of Participants Who Achieved PASI 90 Response at Week 12Week 12PASI 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%-100% involvement), and for erythema, induration, and scaling, which are each rated on a scale of 0 to 4 that is none to maximum severity. The PASI produces a numeric score that can range from 0 (no psoriasis) to 72 (disease severity). A higher score indicates more severe disease. Participants with \>=90% improvement in PASI from baseline were considered PASI 90 responders.

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 that is none to maximum severity. The PASI produces a numeric score that could range from 0 (no psoriasis) to 72 (disease severity). PASI 50, 75, 90, and 100 responders were defined as \>=50%, \>=75%, \>=90%, and 100% improvement in PASI component from Baseline respectively. TF criteria- discontinued study agent due to lack of efficacy or adverse event of psoriasis or who started protocol-prohibited medication/therapy.

Time frame: Week 12

Population: FAS. Participants meeting one or more TF criteria were considered as non-responders.

The PGA is used to determine the participant's psoriasis at a given time point. Overall lesions are graded for induration, erythema, and scaling. The participant's psoriasis was assessed as cleared (0), minimal (1), mild (2), moderate (3), marked (4), or severe (5). Higher scores indicated worse disease.

Time frame: Weeks 80, 104, 128, 152, 176

Population: FAS; all participants enrolled in the LTE who received at least an injection of ustekinumab at Week 56 (partial or complete). Here N (number of participants analyzed) signifies participants who were evaluable for this outcome measure and 'n' (number analyzed): participants evaluated at given timepoints.

Percent Change From Baseline in PASI Score at Weeks 4, 8, 12, 16, 28, 40, and 52

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 that is none to maximum severity. The PASI produces a numeric score that could range from 0 (no psoriasis) to 72 (disease severity). PASI 100 responders were defined as 100% improvement in PASI from Baseline respectively. TF criteria- discontinued study agent due to lack of efficacy or adverse event of psoriasis or who started protocol-prohibited medication/therapy.

Time frame: Baseline and Weeks 4, 8, 12, 16, 28, 40, 52

Population: FAS. For participants meeting one or more TF criteria, were considered to have 0% improvement from baseline. Here 'n' (number analyzed) included all participants who were evaluable at specified timepoints.
