Conditions: Lupus Erythematosus, Systemic Systemic Vasculitis Isolated Angiitis of Central Nervous System Lung Disease With Systemic Sclerosis Lung Disease Interstitial Diffuse
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 14
Healthy volunteers: no

Brief summary:
The purpose of this study it to determine whether the use of a gonadotropin releasing hormone (GnRH)-agonist (depot-leuprolide acetate) during cyclophosphamide (CYC) therapy in women with rheumatic diseases will provide greater ovarian protection than placebo.

Detailed description:
Patients will be women ages 18-40 with either a severe rheumatic disease requiring cyclophosphamide or interstitial lung disease requiring cyclophosphamide to be administered either daily orally; monthly intravenously; or intravenously every 2 weeks for 6 doses. Because cyclophosphamide treatment may be required urgently for some indications, study entry may occur before either the first or second dose of cyclophosphamide for patients receiving cyclophosphamide intravenously.

Of 16 participants who were screened, only 14 were randomized and only 7 participants actually completed the study. Due to this low number, follicle stimulating hormone (FSH) levels were not obtained.

Secondary outcome measures that are not available include presence of menses and FSH.

Arms:
arm 1: Monthly depot leuprolide acetate 3.75 mg injection during cyclophosphamide administration. First dose of study drug given at least 10 days before following dose of cyclophosphamide if cyclophosphamide is given in biweekly or monthly boluses arm 2: Monthly placebo injection during cyclophosphamide administration. First dose of study drug given at least 10 days before following dose of cyclophosphamide if cyclophosphamide is given in biweekly or monthly boluses.

Interventions: intervention 1: depot leuprolide acetate 3.75 mg intervention 2: Placebo
Intervention descriptions: intervention 1: Monthly depot leuprolide acetate 3.75 mg vs placebo during cyclophosphamide administration. First dose of study drug given at least 10 days before following dose of cyclophosphamide if cyclophosphamide is given in biweekly or monthly boluses intervention 2: Monthly placebo during cyclophosphamide administration. First dose of study drug given at least 10 days before following dose of cyclophosphamide if cyclophosphamide is given in biweekly or monthly boluses
