Arms Assigned Interventions
Active Comparator: Active Drug: Darbepoetin alfa
Subjects randomised to active treatment group receive darbepoetin alfa sc Q2W until Hb is stabilised, then move to QM dosing for remainder of treatment period (36 weeks maximum) . Starting dose is calculated at 0.75ug/kg body weight at randomisation, rounded to nearest prefilled syringe dose unit. Dose is titrated incrementally. QM dose is initially double the Q2W dose at time of conversion. Doses available are 10,15,20,30,40,50,60,80,100,150,200 and 300ug, administered via prefilled syringe.
Placebo Comparator: Placebo Drug: Placebo
Subjects randomised to placebo group have Q2W dosing (prefilled syringe placebo sc, to match active arm) for 16 weeks, followed by QM dosing for remainder of treatment period (ie maximum of 36 weeks).

Detailed Description:

This is a multicentre, randomised, single-blind, placebo-controlled, two-arm parallel group study assessing the effect of anaemia correction and Hb maintenance with darbepoetin alfa in elderly CKD subjects over 36 weeks.
