Participant Flow

This study was activated on December 9, 1997, accrued its first patient on March 4, 1998, and closed on June 1, 2004. A total of 118 patients were enrolled (110 ECOG patients and 8 Canadian Leukemia Study Group \[CLSG\] patients).

Participant milestones

Participant milestones
Measure
Supportive Care
Patients received red cell and platelet transfusions for symptoms or to maintain hematocrit at or above 25% by volume. Patients who required transfusion support for symptomatic anemia prior to entering the study and who developed an increase in their transfusion requirement of \>= 50% shall cross over to the Erythropoietin treatment arm, after at least four months on the supportive therapy arm.
Erythropoietin
Erythropoietin was administered at 150 units/kg subcutaneously every day. If patients stopped responding, they were subsequently treated with Erythropoietin (150 units/kg) and filgrastim and then Erythropoietin (300 units/kg) and filgrastim.

SECONDARY outcome

Timeframe: Assessed at 4 months

Population: Only patients who completed quality of life assessment at 4 months were included in this analysis.

The FACT-G scale has 4 dimensions, including physical well-being, social/family well-being, emotional well-being, and functional well-being. The score for each subscale was added together to obtain the total FACT-G score that was evaluated on this study. The total FACT-G score ranges from 0 to 108 with higher scores reflecting better quality of life. It was administered at the time of study entry, every 4 months for the first year, and at the time patient went off treatment. Due to limited data after 4 months on treatment, the analysis was restricted to the four-month time point.

Supportive Care (Step 1)
n=56 participants at risk
Patients received red cell and platelet transfusions for symptoms or to maintain hematocrit at or above 25% by volume. Patients who required transfusion support for symptomatic anemia prior to entering the study and who developed an increase in their transfusion requirement of \>= 50% shall cross over to the Erythropoietin treatment arm, after at least four months on the supportive therapy arm.
Erythropoietin (Step 1)
n=53 participants at risk
Erythropoietin was administered at 150 units/kg subcutaneously every day. If patients stopped responding, they were subsequently treated with Erythropoietin (150 units/kg) and filgrastim and then Erythropoietin (300 units/kg) and filgrastim.
Erythropoietin (Cross-over; Step 2)
n=26 participants at risk
Patients in the supportive care arm who required transfusion support for symptomatic anemia prior to entering the study and who developed an increase in their transfusion requirement of \>= 50% shall cross over to the Erythropoietin treatment arm, after at least four months on the supportive therapy arm. Erythropoietin was administered at 150 units/kg subcutaneously every day.
Erythropoietin (150 Units/kg) and Filgrastim (Step 3)
n=31 participants at risk
All patients received erythropoietin alone treatment may, at progression or at stable disease with continued transfusion requirement following 4 months of therapy, add filgrastim.
Erythropoietin (300 Units/kg) and Filgrastim (Step 4)
n=13 participants at risk
All patients received erythropoietin (150 units/kg) and filgrastim may, at progression or at stable disease with continued transfusion requirement following 4 months of therapy, increased their dose of erythropoietin to 300 units/kg.
