Estimated Enrollment: 35
Study Start Date: April 1999
Primary Completion Date: August 2007 (Final data collection date for primary outcome measure)
Detailed Description:

PROTOCOL OUTLINE: Patients receive cyclophosphamide IV on days 1-4 and filgrastim (G-CSF) beginning on day 10 and continuing until blood counts recover.

Patients are followed monthly for 6 months, every 2 months for 6 months, every 4 months for a year, and then annually thereafter.


Ages Eligible for Study:   18 Years to 70 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No


--Disease Characteristics--

Definitive diagnosis of pemphigus, including all of the following: Typical clinical lesions Histologically proven by skin or mucous membrane biopsy Pemphigus IgG autoantibodies in skin or mucous membrane by direct immunofluorescence (IF) Circulating pemphigus IgG autoantibodies in serum by indirect IF

Dependence on high-dose corticosteroids

Persistent disease activity despite treatment with mycophenolate mofetil or azathioprine, or inability to tolerate these drugs (for paraneoplastic pemphigus, persistent disease activity despite treatment with cyclosporine)

--Prior/Concurrent Therapy--

No concurrent cytotoxic therapy

--Patient Characteristics--

Performance status: Karnofsky 20-100%

Renal: Creatinine no greater than 2.5 mg/dL

Cardiovascular: LVEF at least 40%

Pulmonary: FVC, FEV1, or DLCO at least 50% predicted

Other: Not pregnant Fertile patients must use effective contraception during and for 9 months after study Not preterminal or moribund
