Study Arms (1)
Guselkumab for PG
EXPERIMENTALSubjects with PG will be treated with 100 mg every 4 weeks of guselkumab for 28 weeks in addition to starting stable dose (at least 2 weeks) of prednisone at 20 mg daily. Prednisone will be tapered based on a pre-established algorithm assessed by investigator.
Interventions
Subjects with PG will be treated with 100 mg in a pre-filled syringe to be injected subcutaneously every 4 weeks for 28 weeks.
Eligibility Criteria
You may qualify if:
- Willingness to comply with study procedures/requirements
- Capable of giving informed consent
- Diagnosis of at least one PG ulcer by clinical, histological and laboratory assessments with a minimum wound size of 4 cm2.
- Undergoing at least once a week standard of care wound care at home or at a wound care facility
- Are candidate for systemic therapy. Must be on a stable dose of prednisone of 20 mg/day for at least two weeks prior to first drug administration.
- Males ages 18-99 who agree to not father a child or donate sperm while on study and at least 12 weeks following last dose of the study drug. If subject is sexually active male and could cause pregnancy, subject much be sure that female partner(s) are using birth control that works well or not have sex.
- Females ages 18-99; either of non-childbearing potential or of childbearing potential who test negative for pregnancy and agree to use at least two reliable methods of birth control or remain abstinent during the study for at least 12 weeks following the last dose of guselkumab.
- Willingness to travel to study site for all study visits or living \>30 miles from study site and willing/able to participate in remote videoconferencing visits with access to a computer with internet and webcam capabilities.
- Be willing to undergo perilesional and non-lesional skin biopsy at week 0 and week 32 resulting in 4 biopsies during the course of the study. Participants can choose if they are willing to provide 2 additional biopsies at week 16. Refusal to give consent for any of the optional research samples does not exclude participant from participation in the study.
You may not qualify if:
- Has previously received at any time any therapeutic agent directly targeted to IL-23 including, but not limited to, guselkumab, risankizumab, tildrakuzumab, or mirikizumab
- Any drug treatment specifically for PG including but not limited to biologics (or biosimilar of), experimental antibodies, small molecules and oral immunosuppressives used within washout periods specified below, prior to first dose of study drug:
- weeks for ustekinumab, ixekizumab, secukinumab, brodalumab;
- weeks for infliximab;
- weeks for adalimumab;
- weeks for cyclosporine A, etanercept, inhibitors of the JAK/TYK pathway and PD4 inhibitors;
- weeks for Calcineurin inhibitor topicals (including but not limited to pimecrolimus and tacrolimus) and other advanced topicals (including but not limited to roflumilast and tapinarof).
- If not specified specifically, a time of 4 weeks or 5 half-lives of the drug (whichever is longer) prior to first drug administration.
- Intralesional corticosteroids within 4 weeks of screening.
- Active clinically infected ulcers. Individuals will be eligible for enrollment following completed treatment and resolution of infection. Antibiotics for wound superinfection are allowed.
- Immunomodulating medications for managing underlying comorbidities associated with PG, but not PG itself (e.g., for irritable bowel disease (IBD) or rheumatoid arthritis), are allowed as combination therapy except for Methotrexate (MTX) and Leflunomide which are allowed individually but not in combination.
- Concurrent skin disease that is deemed to interfere with assessment of ulcer.
- Have signs or symptoms suggestive of possible lymphoproliferative disease, including lymphadenopathy or splenomegaly or a history of lymphoproliferative disease within 5 years before screening; or currently has a known malignancy or has a history of malignancy within 5 years before screening, with the exception of a nonmelanoma skin cancer that has been adequately treated with no evidence of recurrence for at least 3 months before the first study drug administration or cervical carcinoma in situ that has been treated with no evidence of recurrence for at least 3 months before the first study drug administration.
- Recent (within past 6 months) cerebrovascular accident, myocardial infarction, coronary stenting. Uncontrolled hypertension - confirmed systolic blood pressure \>160 mmHg or diastolic blood pressure \>100 mm Hg.
- Clinically significant (per investigator's judgement) drug or alcohol abuse within the last 6 months preceding the Baseline Visit.
