Tolerability and efficacy of multidose epoetin beta (Reco-Pen) for subcutaneous administration in patients with anemia due to renal failure.

Abstract

AIMS:

To assess the tolerability, safety and efficacy of the epoetin beta multidose cartridge formulation, self-administered subcutaneously via a pen device (Reco-Pen), in adult patients with renal anemia.

METHODS:

Patients receiving maintenance epoetin therapy were switched to the subcutaneous (SC) multidose formulation of epoetin beta (NeoRecormon). The frequency of adverse events, local tolerability, and changes in blood pressure and laboratory variables were recorded. Hematologic parameters, transfusion requirements and epoetin beta dosage were also assessed.

RESULTS:

A total of 406 patients were entered in the intention-to-treat analysis. Mean treatment duration was 82.3 days. Fifty patients (12.3%) withdrew from the study; 14 (3.4%) discontinued because of adverse events. Treatment was well tolerated, with adverse events considered probably related to treatment in only 5 cases, and 1 case of local intolerability. There were no clinically significant changes in blood pressure or laboratory variables, and no changes in hematologic parameters or transfusion requirements. Unexpectedly, the epoetin beta dose was reduced by almost one-third in patients previously maintained on SC epoetin.

CONCLUSION:

SC administration of this multidose epoetin beta formulation with the Reco-Pen device was well tolerated and effective. It is possible that the improved capacity to individualize dose may have contributed to the considerable reduction in SC epoetin beta dosage requirement.
