Altro: Observational Group
Participants in the observation group were evaluated once every 2 weeks for the first 12 weeks (test period).
No darbepoetin alfa was administered to the observation group during this period.
Darbepoetin alfa could be initiated at a dose of 3.0 μg/kg once every 2 weeks beginning with the first visit after the test period at which the participants hemoglobin concentration was less than or equal to 11.0 g/dL.
The dose of darbepoetin alfa could be increased to 5.0 μg/kg once every 2 weeks after 6 weeks of darbepoetin alfa treatment in participants with a hemoglobin change from baseline of less than 1.0 g/dL.
|
Administered subcutaneously.

Comparatore attivo: 21 week treatment group
Participants in the treatment group received darbepoetin alfa subcutaneously (SC) at a dose of 3.0 μg/kg once every 2 weeks for 21 weeks.
The dose of darbepoetin alfa could be increased at week 7 (to 5.0 μg/kg once every 2 weeks) or at week 13 (to 9.0 μg/kg once every 2 weeks) in participants with a hemoglobin change from baseline of less than 1.0 g/dL who dose escalated at week 7.

Administered subcutaneously.

Change in Functional Assessment of Cancer Therapy (FACT)-Fatigue Score at Week 13
Lasso di tempo: Baseline (Week 1) and Week 13
|
The FACT-Fatigue scale comprises 13 questions evaluating the impact of anemia on cancer patients with various tumor types receiving chemotherapy.
Fatigue scores range from 0 to 52, with a higher score indicating less fatigue.

Hemoglobin Response During the Test Period
Lasso di tempo: Weeks 1-12
