Female patients of childbearing potential must have negative pregnancy test within 7 days before initiation of study drug dosing. Postmenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential.

Have previously received any treatment agent directly targeted at reducing IL-12 and/or IL-23. 8. Have received, within 2 weeks prior to the first dose of ustekinumab, a live virus or bacterial vaccination. 9. Have received, or are expected to receive, a BCG vaccination within 12 months prior to screening, during study, or within 12 months after the last administration of study agent. 10. Have a serious infection (eg sepsis, pneumonia or pyelonephritis). 11. Have a transplanted organ (with exception of a corneal transplantat in situ). 12. Have a known history of lymphoproliferative disease. 13. Have any known malignancies or have history of malignancy (with the exception of basal cell carcinoma, squamous cell carcinoma with tumor thickness =2mm, or cervical carcinoma in situ that has been treated with no evidence of reccurence within 1 year prior to the first administration of study agent). 14. Have a known hypersenstitivity to ustekinumab or any of its excipients. 15. Is a prisoner 16. Participation in another clinical trial whilst this study or within the last 30 days preliminary to this study 17. Have any condition that, in the opinion of the investigator, would compromise the well being of the patient or the study.

Primary
| Measure | Time frame |
|---|---|
| Main Objective: To confirm the efficacy and immunological response of Stelara® therapy in patients with PG;Primary end point(s): Change of the PG-inflammation SCORE from baseline to week 28;Timepoint(s) of evaluation of this end point: week 28 ;Secondary Objective: - To assess changes in PG-inflammation Score, Wound Score and Visual Analogue Pain Scale (VAPS). - To assess the safety and tolerability of Stelara in patients with PG. - To assess, where feasible, the functional significance of the expression pattern of inflammatory cytokines, particularly IL-23, in PG tissue as obtained by biopsies before the beginning of and after the treatment with Stelara and by blood samples before, during and after treatment with Stelara • Evaluation of the expression of these cytokines and/or associated inflammatory molecules • Assessment of the type of Th immune response before, during and after treatment with Stelara • Correlation of the results from the analyses mentioned above with the clinical outcome of PG patients. - To asses changes in quality of life, including the dermatology Life Quality Index (DLQI) | — |
