The official eligibility criteria
Registry text, reproduced exactly. These are the words the trial's sponsor published on ClinicalTrials.gov. They have not been edited, shortened or rewritten, and they are written for researchers rather than for patients.
Inclusion Criteria:

* Must have received benefit from continued guselkumab therapy in the opinion of the investigator
* Before enrollment, a participant must be either: (a) Not of childbearing potential, OR (b) Of childbearing potential and not sexually active, practicing abstinence or a highly effective method of contraception and agrees to remain on a highly effective method while receiving study intervention and until 12 weeks after the last dose - the end of relevant systemic exposure
* Parent(s) (or their legally acceptable representative) must sign an informed consent form (ICF) indicating that he or she understands the purpose of, and procedures required for, the study and is willing to allow the child to participate in the study. Assent is required from participants who are capable of understanding the nature of the study, typically those aged 7 years and older, to ensure their willingness to participate. An adolescent who provides assent will have the opportunity to sign an adult ICF upon reaching the age of majority, thereby affirming their understanding of the study's purpose and procedures, as well as their willingness to participate.

Not medical advice.
Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
