Outcomes

Primary Outcome Measures

Cessation of Blister Formation
Median time to cessation of blister formation during the 12 weeks of therapy.

Secondary Outcome Measures

Change in Bullous Pemphigoid Disease Activity Index (BPDAI)
The change in Bullous Pemphigoid Disease Activity Index (BPDAI) from week 0 to 12 of treatment will be measured.The BPDAI is a standard scoring system for cutaneous disease activity and pruritus in BP. BPDAI is predictive of the likelihood of a subsequent flare. The BPDAI consists of scoring various types of lesions and creates a score ranging from 0 to 120. A score of greater than 56 is considered severe disease.
Prednisone Dose (mg)
Average daily prednisone dose (mg) will be calculated for each Epoch.
Number of Participants With Treatment-related Adverse Events as Assessed by the Common Terminology Criteria for Adverse Events Version 4.0 (CTCAE v4.0).
The clinical safety of Ixekizumab will be monitored with collection of vital signs, clinical examination, and clinical laboratory studies. Adverse events (AE) will be reported per the Common Terminology Criteria for Adverse Events (CTCAEv4.0), a descriptive terminology which can be utilized for AE reporting. A grading (severity) scale is provided for each AE Grade refers to the severity of the AE. The CTCAE displays Grades 1-5 with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local or noninvasive intervention indicated; Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; Grade 4 Life-threatening consequences; urgent intervention indicated. Grade 5 Death related to AE.
Decrease in Immunoglobulin G Anti-Bullous Pemphigoid 180 and 230 Antibody (Anti-BP180 & 230 IgG)
We will measure the anti-BP180&230 antibodies through out treatment. These assays will be completed using and ELISA assay. Mayo medical labs references for anti-BP180&230 (<9.0 Units negative, > or = 9.0 Units positive)
Decrease in Neutrophil and Eosinophil Counts
Neutrophil and eosinophil counts will be monitored throughout therapy. Mayo medical labs reports normal neutrophil levels (1.70-7.00X10(9)/L) and normal eosinophil levels (0.05-0.5X10(9)/L)
Change in Multiplex Cytokine Analysis
Multiplex cytokine analysis will be performed throughout therapy on Interleukin (IL)- 6, 17, 22, 23, Transforming growth factor beta (TGFb), and matrix-metalloprotease-9 (MMP9).

5. Study Description

Brief Summary
Recently, Interleukin (IL)-17 has been identified as a key driver of chronic inflammation in Bullous Pemphigoid (BP). Ixekizumab is a recombinant high-affinity fully human monoclonal antibody that targets IL-17A Immunoglobulin gamma-1 (IgG1)/kappa-class. The purpose of this study is to determine the effect of Ixekizumab on BP patients.
Detailed Description
BP is the most common auto-immune blistering disease of the skin and causes significant morbidity. BP disproportionally affects the elderly population and the current, non-specific immunosuppressive therapies, in addition to patient comorbidities, are associated with a high risk of infection related mortality. Neutrophils and their proteases have been shown to play a major role in the cleavage of Bullous Pemphigoid 180 Antigen (BP180) in BP. Mast cells and other cellular mediators also contribute to the pro-inflammatory environment within and surrounding blisters of BP. However, the prior targeting of mast cells and basophils has resulted in unpredictable disease control. Recently, IL-17 has been identified as a key driver of chronic inflammation in BP. With the increasing aged population in the United States, BP will increase in prevalence and the development of a more targeted approach will be necessary to decrease morbidity and mortality. IL-17 inhibition with Ixekizumab may have targeted, disease-modifying effects on BP. The primary objective is to test the effect of Ixekizumab in the treatment of the autoimmune blistering disease, BP.
