    Abstract:
    SUMMARY BACKGROUND: Less frequent dosing regimens during anemia treatment could benefit Peritoneal Dialysis (PD) patients. We investigated the effectiveness of darbepoetin alfa dosed every-other-week (Q2W) for maintaining hemoglobin (Hb) levels (11-13 g/dL). PATIENTS AND METHODS: One hundred and nine PD patients from 14 centers participated in an 8-month observational, prospective study. Patients (Hb 11-13 g/dL) receiving weekly (QW) darbepoetin alfa switched to Q2W dosing at the investigator's discretion. Doses were adjusted according to published guidelines. RESULTS: Sixty-nine percent (75 out of 109) of patients switched to Q2W dosing. Thirty-three percent maintained the g/week, equivalent to twice the previous mean weekly dose (26.1-25.8 g/week, QW dose). Forty-seven percent received a dose reduction (35.8-20.2 equivalent to the previous QW dose). More patients in the maintenance dose group 11 g/dL than those receiving a reduced weekly dose (80% vs. had Hb levels 51.4%, respectively, p = 0.0236). During the Q2W phase, the mean Hb level ranged from 12.0-12.5 g/dL for the maintenance dose group and 11.5-12.0 g/dL for the reduced dose group. From the switch to the end of the study, the mean (SD) change in Hb was -0.7 g/dL (0.98 g/dL, p = 0.0557) and -0.6 g/dL (1.6 g/dL, p = 0.1296) for the maintenance and reduced dose groups, respectively. The Q2W darbepoetin alfa was well tolerated. Only a single treatment-related adverse event (polycythemia) occurred. CONCLUSION: The majority of PD patients receiving QW darbepoetin alfa can be effectively switched to Q2W and still maintain their Hb level.
