Brief Summary

An Open-Label, Proof-Of-Concept, Study of Baricitinib for the Treatment of Pyoderma Gangrenosum

Detailed Description

This is a Phase II study that will be open label and include a total of 20 patients who will receive the investigational product. PG will be defined by the investigator and a second reviewer on the basis of results from clinical, histological and laboratory assessments. These patients will undergo 24 weeks of baricitinib dosed daily and stable dose of prednisone dosed daily with follow-up until week 36.

Subjects with PG will be treated with 4 mg once daily of baricitinib for 24 weeks in addition to starting stable dose (at least 2 weeks) of prednisone at 30 mg daily. Prednisone will be tapered based on a pre-established algorithm assessed by investigator.

Eligibility Criteria

Inclusion Criteria

• 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.
• Male age 18-99 who agree to not father a child or donate sperm while on study and at least 1 week following last dose of the study drug. If subject is a sexually active male and could cause a pregnancy, subject must be sure that female partner(s) are using birth control that works well or not have sex.

• Classic PG defined as deep ulceration with undermining violaceous borders.
• Are candidate for systemic therapy. All participants will be taking and clinically stable 30 mg (same ulcer size) of prednisone fort least two weeks at the start of the study. Patients must have discontinued immunosuppressive therapies (cyclosporine, azathioprine, mycophenolate mofetil, methotrexate, apremilast, dapsone) due to inadequate response or intolerance for at least 4 weeks prior to beginning the study drug.
• Undergoing at least once a week standard of care wound care at home or wound care facility.
• Willingness to travel to Oregon Health and Science University (OHSU) for all study visits, or living >30 miles from OHSU and willing/able to participate in remote videoconferencing visits with access to a computer with internet and webcam capabilities.

Exclusion Criteria

• Have history of malignancy or lymphoproliferative disease; or have signs or symptoms suggestive of possible lymphoproliferative disease, including lymphadenopathy or splenomegaly; or have active primary or recurrent malignant disease; or have been in remission from clinically significant malignancy for < 5years.
• Patients with cervical carcinoma in situ, basal cell carcinoma or squamous cell carcinomas who have had active disease within 3 years of screening for this study. Active, untreated, acute or chronic infection (such as untreated tuberculosis), or immunocompromised to an extent that such that participation in the study would pose an unacceptable risk to the subject. (Treated infections such as latent tuberculosis after completion of the appropriate therapy are not excluded.Patients currently on treatment for active TB with drugs such as strong OAT-3 inhibitors will be excluded from study)
• Clinically serious infection or received intravenous antibiotics for an infection, within 4 weeks of randomization.
• Active viral infection that, based on the investigator's clinical assessment, makes the subject and unsuitable candidate for the study.
• Positive for human immunodeficiency virus, hepatitis B virus, or hepatitis C virus.
• Symptomatic herpes zoster infection within 12 weeks of screening or recurrent or disseminated (even a single episode) herpes zoster.
• Symptomatic herpes simplex at the time of randomization or disseminated (even a single episode) herpes simplex
• History of disseminated opportunistic infections (e.g., listeriosis and histoplasmosis).

1. Aged >65 years.

2. Body mass index (BMI) >35 kg/m2.

3. Oral contraceptive use and current smoker.

• Creatinine Clearance <30 mL/min
• Wound care debridement of any PG ulcer within 2 weeks.
• Intralesional corticosteroids within 4 weeks of screening.
• Previous exposure to a Janus kinase (JAK) inhibitor (ruxolitinib, tofacitinib, upadacitinib, filgotinib). For biologic therapies, the specific washout periods used will at least 4 weeks for anakinra, etanercept, infliximab, adalimumab, alefacept, golimumab, secukinumab, ixekizumab, risankizumab, guselkumab, tildrakizumab, canakinumab, ustekinumab and at least 24 weeks for rituximab or efalizumab.
• Patients who are currently on immunosuppressive therapies or have not discontinued them for at least 4 weeks.
• Clinically significant (per investigator's judgement) drug or alcohol abuse within the last 6 months preceding the Baseline Visit.
• Have a live vaccine within 12 weeks prior to baseline or intend to have a live vaccine during the course of study.
• Had any major surgery within 8 weeks prior to baseline or will require major surgery during the study, which in the opinion of the investigator would pose an unacceptable risk to the subject.
• 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.
• Gastrointestinal (GI) perforation (other than appendicitis or penetrating injury), diverticulitis or significantly increased for GI perforation (within past 6 months) per investigator judgement; any condition could interfere with drug absorption including but not limited to short bowel syndrome.
• Presence of significant uncontrolled respiratory, hepatic, renal, endocrine, hematologic, neurologic, or neuropsychiatric disorders, or abnormal laboratory screening values that, in the opinion of the investigator, pose an unacceptable risk to the subject if participating in the study or of interfering with the interpretation of the data.
• Have clinical laboratory test results at screening that are outside the normal reference range of the population and are considered clinically significant, or have any of the following specific abnormalities: Neutrophil count <1500 cells/µL, lymphocyte count <500 cells/µL, platelet count <100,000 cells/µL, aspartate transaminase (AST) or alanine aminotransferase (ALT) > 2 times the upper limit of normal, hemoglobin <10 g/dL for male and female subjects, eGFR>60.
• Women who are lactating or breastfeeding.
• Have any other condition that precludes the subject from following and completing the protocol, in the opinion of the investigator.
• Are investigator site personnel directly affiliated with this study and/or their immediate families (spouse, parent, child, or sibling).
• Are currently enrolled in, or discontinued from a clinical trial involving an investigational product or non-approved use of a drug or device within the last 4 weeks or a period of at least 5 half-lives of the last administration of the drug, whichever is longer, or concurrently enrolled in any other type of medical research judged not to be scientifically or medically compatible with this study.
• History of myocardial infarction, stroke and New York Heart Association Stage II/IV heart failure
• Patients on concomitant medication with a Strong OAT-3 inhibitor for an existing condition will be excluded from study
