a study on Pustular Dermatosis
Background: - Inflammatory pustular skin diseases are a type of autoinflammatory disease in which the immune system attacks the body s tissues. These diseases cause painful and itchy skin rashes, eye and mouth irritation, joint pain and fever. Several drugs for treating these diseases suppress the immune system. However, they can cause severe side effects when taken over a long period of time. - IL-1 is a small protein that may be important in causing the inflammation seen in pustular skin disease. Anakinra is a drug that works by blocking IL-1. It has been effective in treating some inflammatory conditions such as rheumatoid arthritis. However, anakinra has not been studied for use in patients with pustular skin disease. Researchers want to see whether anakinra will be effective in treating pustular skin disease. Objectives: - To see if anakinra can be used to treat inflammatory pustular skin disease. Eligibility: - Individuals at least 18 years of age who have inflammatory pustular skin disease. Design: - Participants will be screened with a physical exam and medical history. Their disease will be evaluated with blood tests, urine tests and imaging studies. Skin biopsies may also be collected. - Participants will have an initial visit to receive the first dose of anakinra. They will be shown how to give themselves daily injections of anakinra. - Participants will take anakinra for up to 12 weeks as long as there are no severe side effects. During this time, they will keep a study diary to record the severity of any rashes, pustules, itching, fevers, and skin or joint pain. They will bring this diary to their study visits. - Participants will have study visits at weeks 4, 8 and 12. Treatment will be monitored at these visits with blood tests, urine tests and physical exams. Depending on the effects of the treatment, participants may have the dose of anakinra increased or decreased. - Participants will have a final study visit 4 weeks after they stop taking anakinra.
A Phase 2 Study of Anakinra in Inflammatory Pustular Dermatoses: Evaluation of Therapeutic Efficacy and Validation of Pathogenic Mechanisms
-To characterize the clinical efficacy, optimal dosing and safety of anakinra in patients with pustular dermatoses.

leukocytes greater than or equal to 3,000/mcL
absolute neutrophil count greater than or equal to1,500/mcL
platelets greater than or equal to 100,000/mcL
creatinine within normal institutional limits OR creatinine clearance greater than or equal to 60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal.
1.7 Quantiferon TB Gold must be performed for screening for mycobacterium tuberculosis infection. However, a tuberculin skin test may be placed if the Quantiferon TB gold test is indeterminate. Patients must have a negative Quantiferon TB Gold (or tuberculin skin test) or evidence of appropriate treatment prior to study entry.
1.8 Patients must be able to understand and sign a written informed consent document and complete study-related procedures and questionnaires.
2.1 Enrollment in any other investigational treatment study or use of an investigational agent, or has not yet completed at least 3 half-lives since ending another investigational device or drug trial.
2.2 History of treatment with canakinumab within the 12 months prior to study initiation.
2.3 History of anakinra use.
2.4 History of phototherapy within 2 weeks prior to study initiation.
2.5 Patients may NOT concurrently be on biologic therapy such as etanercept, adalimumab,alefacept, infliximab, rituximab or rilonacept. If there is a history of use of biologic agents, there must be a washout period of at least 3 half-lives prior to study initiation.
2.6 Subjects who experience a significant flare after discontinuation of a TNF inhibitor as part of this study that requires urgent medical management or hospitalization, or in the estimation of the principal investigator poses excessive risk to the patient to enter the study.
2.7 Other defined dermatologic conditions which may include pustules as part of the clinical presentation, but which clinically and/or histologically do not resemble pustular psoriasis. Examples include, but are not limited to acute generalized exanthematous pustulosis (AGEP, a drug-induced pustular dermatosis typically caused by beta-lactam antibiotics, tetracyclines, oral antifungals and other drugs), bacterial or fungal folliculitis, cutaneous candidiasis, tinea pedis, tinea corporis, neutrophilic eccrine hidradenitis or eosinophilic pustular folliculitis (Ofuji syndrome).

2.9 History of allergic reactions attributed to compounds of similar chemical or biologic composition to anakinra or other agents used in study. Known hypersensitivity to CHO-cell derived biologics or any components of anakinra.
2.10 Treatment with a live virus vaccine during the 3 months prior to baseline visit. No live vaccines will be allowed throughout the course of this study.
2.11 Patients with active or untreated malignancy-- with the exception of cutaneous basal or squamous cell carcinomas, or in situ cervical carcinoma-- are ineligible because of the immunomodulating effects of anakinra. The risk of recurrent malignancy secondary to this drug is unknown.
