| Experimental: JNJ-77242113<br>Adolescent and adult participants will receive JNJ-77242113 from Week 0 through Week 156. At Week 24, adult participants who are psoriasis area and severity index (PASI) 75 or investigator global assessment (IGA) score of 0 or 1 responders (that is, those who achieve an IGA score of 0 or 1 and have >=2-grade improvement from baseline) will be re-randomized either to continue JNJ-77242113 or to placebo (and will be retreated with JNJ-77242113 upon loss of >=50% of their Week 24 PASI improvement). Adult participants identified as both PASI 75 and IGA 0 or 1 score non-responders will continue to receive JNJ-77242113 through Week 52. From Week 52 to Week 156, all adult participants will receive JNJ-77242113. Adolescents will not participate in re-randomization regardless of their PASI score or IGA score at Week 24.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants Achieving an Investigator's Global Assessment (IGA) Score of 0 or 1 and Greater Than or Equal to (>= )2-Grade Improvement From Baseline to Week 16 | 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). | Baseline to Week 16 | 
| Percentage of Participants Achieving Psoriasis Area and Severity Index (PASI) 90 Response at Week 16 | Percentage of participants achieving PASI 90 response (>=90% improvement in PASI from baseline) at Week 16 will be 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 and scored separately for erythema, induration, and scaling, which are each rated on a scale of 0 to 4 and extent of involvement on a scale of 0 to 6. The PASI produces a numeric score that can range from 0 to 72. A higher score indicates more severe disease. | Baseline to Week 16 |
