Clinical Trial Summary

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


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.

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). - Have a history of venous thromboembolism (VTE), or are considered at high risk for VTE as deemed by the investigator, or have 2 or more of the following risk factors for VTE: 1.

Outcome

Type Measure Description Time frame Safety issue
Other Evaluation of cytokine gene expression 15. Evaluation of cytokine gene expression before and after treatment in skin, wound fluid, saliva and blood samples Week 0 and week 24
Primary Healing defined as the proportion of patients with complete re-epithelization, defined as 100% re-epithelialization without any drainage, of the target ulcer at week 24. Week 24
Secondary Physician Global Assessment (PGA) Assessing the proportion of patients that show target ulcer healing in response to study treatment as measured by achieving PGA between 0 and 1 after treatment with baricitinib at week-36 52. This scale has been used in previous trials:
0 = total resolution of target ulcer with no signs of active PG
1= almost completely healed target ulcer with only minimal signs of active PG
2 = evidence of target ulcer healing which involves at least 50% of ulcer/ulcer margin
3 = evidence of target ulcer healing which involves less than 50% of ulcer/margin
4 = no evidence of target healing ulcer
Week 24
Secondary Percent change in lesion surface area The percent change in surface area of target lesion of PG (two-dimensional surface in cm²) using digital photography and acetate tracing at Week 0 and Week 24 Week 0 and 24
Secondary Mean change in lesion surface area The mean change in surface area of target lesion of PG (two-dimensional surface in cm²) using digital photography and acetate tracing Week 0 and 24
Secondary Mean change in Physician Global Assessment (PGA) The mean change in Physician global assessment (PGA) 5-point scale at week 0 to week 24 Week 0 and 24
Secondary Sustained healing The proportion of patients with target ulcer that remains healed by week 36 Week 36
Secondary Decrease in ulcer area size The proportion of patients with decrease in ulcer area size of at least 50% after treatment at week 24 Week 24
Secondary Time to healing Time to which sterile dressings are not required. Over 36-week period of study.
Secondary Time to recurrence (weeks) Interval between target lesion healing and further episodes of PG at any site through the study. 36 weeks
Secondary Number of treatment failures Treatment intolerance, number of patients switching into standard of care or target lesion unhealed. By week 24
Secondary Adverse reactions to medications Possibly-, probably- or related throughout the study. Over 24-week period of study.
Secondary Quality of life change (as measured by the Dermatology Life Quality Index) Proportion of subjects achieving a 4-point change in quality of life measured by the Dermatology Life Quality Index (DLQI) at week 24, and mean change in DLQI score at week 24. The DLQI is a validated tool for inflammatory skin conditions. It is a 10-question survey, scored 0 - 30 points. For inflammatory skin conditions, a 4-point change in DLQI score is considered clinically important. Week 24
Secondary Mean change in quality of life (measured by Dermatology Life Quality Index) Mean change in DLQI score from week 0 to week-24. Week 0 and 24
Secondary Skin pain scale The proportion of patients with a 2 point decrease in the point numeric pain rating scale (NRS) at week 0 and week-24. The pain NRS is a subject-administered, 11-point horizontal scale anchored at 0 and 10, with 0 representing "no pain" and 10 representing "worst pain imaginable." Week 0 to 24
