About this study
This study will determine the safety of treatment of bullous pemphigoid in patients resistant to therapy with systemic corticosteroids, with rituximab plus systemic corticosteroids.
Read the detailed description
Bullous pemphigoid (BP) is an autoimmune blistering disease characterized clinically by the presence of severely itchy, tense blisters located over the trunk and extremities. BP is the most common of the autoimmune blistering diseases with an incidence of approximately 10 per 1,000,000 population(1;2). In addition, BP occurs more frequently in the elderly. Routine histopathology reveals a sub-epidermal blister most often with large numbers of eosinophils. Direct immunofluorescence of the skin of patients with BP reveals a linear band of C3 and IgG at the basement membrane zone. Examination of the sera of patients shows the presence of a circulating anti-basement membrane zone autoantibody. This antibody has been found to be directed against a 180 kd protein of the basement membrane zone type XVII collagen (BPAg2) and against a 230 kd protein (BPAg1) found in the epidermal hemi-desmosome(3;4).
BP is a severe disease most often requiring therapy with high dose systemic corticosteroids (0.75 - 1.0 mg/kg/day) often for months(5). In addition, relapses are common and the additional use of immunosuppressive drugs such as azathioprine, methotrexate, cyclosporine A and others are needed to minimize the dose of systemic corticosteroids. The 1-year mortality of BP has been estimated to range from 10 - 30%(1;6). Currently treatment of patients with BP consists of initial use of systemic corticosteroids (0.75 - 1.0 mg/kg/day). Control of symptoms and new blister formation is most often achieved within 1 month and systemic corticosteroids are then tapered. As many as 33 - 50% of patients may not be able to be tapered to clinically acceptable levels of systemic corticosteroids, requiring the addition of systemic immunosuppression often with azathioprine. Approximately 66% of patients require long term treatment with immunosuppressive medication to maintain control of their blistering.(5;7;8) The need for long term systemic corticosteroid therapy often with systemic immunosuppression in an elderly population results in a significant morbidity and mortality in patients with BP. New therapeutic interventions that would potentially allow for the more rapid discontinuation of prednisone, avoidance of systemic immuno- suppression and perhaps earlier clinical relapse would be of substantial benefit to patients with BP. The clinical and laboratory data has demonstrated that BP is an autoantibody mediated blistering disease. Taken together these observations suggest that the use of anti-CD20 antibody (Rituxan) may be useful in the treatment of patients with BP. We have previously treated a patient with BP and graft versus host disease with anti-CD20 and anti-CD25 and were able to achieve clinical and serological remission within 4 weeks of initiation of therapy(9). In addition, others and we have successfully utilized Rituxan for the treatment of pemphigus vulgaris, another autoantibody mediated, autoimmune blistering disease(10-15)

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Rituximab in people with Bullous Pemphigoid, run by Duke University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 11 Apr 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 22 Oct 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Primary Safety Endpoint (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00286325, which also lists 30 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Apr 2013.
