Study of High Dose Cyclophosphamide in Patients With Severe Aplastic Anemia and Paroxysmal Nocturnal Hemoglobinuria

High Dose Cyclophosphamide for the Treatment of Severe Aplastic Anemia and Paroxysmal Nocturnal Hemoglobinuria

OBJECTIVES: I. Confirm the efficacy demonstrated in a pilot study using high dose cyclophosphamide in patients with severe aplastic anemia.

II. Determine whether the addition of filgrastim (G-CSF) to high dose cyclophosphamide shortens the time to recovery in these patients.

III. Determine whether this regimen is efficacious in treating paroxysmal nocturnal hemoglobinuria.

Study Overview

Detailed Description

PROTOCOL OUTLINE: Patients receive high dose cyclophosphamide IV on days 1-4. Beginning on day 10, patients receive filgrastim (G-CSF) until the absolute neutrophil count is greater than 1,000/mm3 for 2 consecutive days.

Patients are followed every 3 months for at least 2 years and annually thereafter.
