Pyoderma Gangrenosum
Conditions
Brief summary
An Open-Label, Proof-Of-Concept, Study of Ixekizumab in the Treatment of Pyoderma Gangrenosum
Detailed description
This is a Phase II study that will be open label and include a total of five patients who will receive the investigational product. These patients will have histological testing to rule out competing etiologies and require 3rd party adjudication/confirmation on agreement of the diagnosis. These patients will undergo 12 weeks of ixekizumab dosed every 2 weeks with follow-up until week 16.

Eligibility
Inclusion criteria
* Major inclusion criteria: * Have a clinical diagnosis of classic Pyoderma Gangrenosum for at least 3 months as determined by the investigator and an external reviewer on the basis of results from clinical, histological and laboratory assessments * At screening, have a Pyoderma Gangrenosum ulcer characterized by 'item a' AND 3/5 features in 'item b' OR 2/5 features in 'item b' with support from one of the conditions listed in c. a. Stable or increasing size within 2 months preceding screening by patient report or documentation b. Features such as violaceous border, undermining, d. Intralesional corticosteroids within 8 weeks of day 0; topical immunomodulators are permitted. e. Wound debridement within 2 weeks of Day 0; dressing changes allowed per investigator discretion. g. Systemic antibiotics within 2 weeks of Day 0 h. Live, attenuated vaccines within 3 months of Day 0; or live, seasonal-flu- or H1N1 vaccines within 2 weeks of Day 0. Note: recombinant- and/or killed vaccines are permitted. i. Hyperbaric treatment within 4 weeks of Day 0 j. Investigational drug or investigational device within 30 days or 5 half-lives of Day 0, whichever is longer k. Prior exposure to ixekizumab l. Other treatments not described above should be maintained at a stable dose and frequency throughout the study as best as possible 13. Major, general surgery within 3 months of screening, or anticipated general surgery during the study period 14. Pregnancy, plans to become pregnant during the course of the study, delivery within 3 months of screening, or breast-feeding 15. If previous use of cyclosporine or systemic corticosteroids, failure to have any stabilization/response is exclusionary. This potentially indicates the disease is not Pyoderma Gangrenosum.

These patients will have histological testing to rule out competing etiologies and require 3rd party adjudication/confirmation on agreement of the diagnosis
Participants by arm
| Arm | Count |
|---|---|
| Ixekizumab (Taltz) We have received funding for only a small pilot study to prove a benefit from Interleukin-17 inhibition in Pyoderma Gangrenosum . Therefore, there is only one treatment arm. The primary outcome will be a comparison of week 12 to baseline regarding a two-point improvement in the Investigator Global Assessment.
