Darbepoetin Alfa and Anemia of Cancer

11 de diciembre de 2013 actualizado por: Amgen

A Randomized, Open-label, Comparative Study to Estimate the Effect of Darbepoetin Alfa on Hospital Days, Economic Outcomes, and Health-related Quality of Life in Subjects With Nonmyeloid Malignancies and Anemia of Cancer

This phase 2, multicenter, randomized, open-label, comparative study was designed to determine the effect of darbepoetin alfa on hospital days, economic outcomes, and health related quality of life (HRQOL) in anemic patients with nonmyeloid malignancies who were not receiving chemotherapy. Participants were randomly assigned in a 4:1 allocation ratio to receive either 21 weeks of darbepoetin alfa treatment (treatment group) or 12 weeks of observation followed by up to 9 weeks of darbepoetin alfa treatment (observation group).

Grupo de participantes/brazo
Intervención / Tratamiento
Otro: 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.

Comparador activo: 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.

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Total Hospital Costs During the Test Period
Periodo de tiempo: Weeks 1-12
The hospital bill database was used to determine the mean total hospital cost per participant during the test period. Participants who were not hospitalized had a cost of $0 imputed.
Weeks 1-12
Change in Functional Assessment of Cancer Therapy (FACT)-Fatigue Score at Week 13
Periodo de tiempo: Baseline (Week 1) and Week 13
