Trial overview
Official title: A four-week, Phase IIa, randomized, active-controlled, parallel-group, multi-center study to evaluate the safety, efficacy and pharmacokinetics of switching subjects from a stable dose of recombinant human erythropoietin to GSK1278863 in hemodialysis-dependent subjects with anemia associated with chronic kidney disease
Trial description: This is a four-week, Phase IIa, randomized, active-controlled, parallel-group, multi-center study to evaluate the safety, efficacy and pharmacokinetics of switching subjects from stable rhEPO to GSK1278863 in approximately 68 hemodialysis-dependent subjects with anemia associated with chronic kidney disease. The study consists of a screening phase of 2 weeks, a 4-week treatment phase and a 2-week follow-up phase. The range of Hgb values for study eligibility is 9.5-12.0 g/dL and the subjects must have received the same rhEPO product with total weekly doses that varied by no more than 50% during the 4 weeks prior to the Screening visit (Week -1. This study aims to estimate the relationship between dose of GSK1278863 and Hgb response in hemodialysis-dependent (HDD) subjects with anemia associated with chronic kidney disease after switching from a stable maintenance dose of recombinant human erythropoetin (rhEPO).

No
- 1. Age and weight: >/=18 years of age and >/=45 kg (weight post-dialysis).
- 2. On three times weekly hemodialysis for at least 8 weeks, irrespective of eGFR values and stage of chronic kidney disease (CKD).
- 1. Dialysis modality: On peritoneal dialysis OR planned change in dialysis modality within the study time period.

Inclusion and exclusion criteria
Inclusion criteria:
- 1. Age and weight: >/=18 years of age and >/=45 kg (weight post-dialysis). 2. On three times weekly hemodialysis for at least 8 weeks, irrespective of eGFR values and stage of chronic kidney disease (CKD). 3. A single-pool Kt/Vurea of >/=1.2 based on a historical value obtained within the prior month in order to ensure the adequacy of dialysis. If Kt/Vurea is not available, then an average of the last 2 values of urea reduction ratio (URR) of at least 65%. 4. rhEPO use: Using the same rhEPO (epoetins or darbepoetin) with total weekly doses that varied by no more than 50% during the prior 4 weeks (i.e., maximum vs. minimum total weekly doses /= 2.0 ng/mL (may rescreen in one month). 8. Ferritin: >/=40 ng/mL with the absence of microcytic or hypochromic RBCs. 9. Transferrin saturation (TSAT): Within the reference range. 10. Iron replacement therapy: Stable maintenance dose of oral iron replacement therapy, if required, that will be maintained throughout the study. NOTE: IV iron replacement therapy is not allowed the two weeks prior to Screening through the end of the study (Week 6). 11. QTc: QTcB <470 msec or QTcB <480 msec in subjects with bundle branch block obtained at Screening Visit (based on Central Reader’s interpretation). 12. Females: Eligible to participate if she is of childbearing potential, and must agree to use one of the approved contraception methods from Screening until completion of the Follow-up Visit OR of non-childbearing potential defined as pre-menopausal females with a documented tubal ligation of hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH)>40MIU/ml and estradiol <40pg/ml is confirmatory]. Females on hormone replacement therapy (HRT) whose menopausal status is in doubt will be required to use one of the approved contraception methods if they wish to continue their HRT during the study. Otherwise they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment. For most forms of HRT, at least 2 weeks will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of their post-menopausal status, they can resume use of HRT during the study without use of a contraceptive method. 13. Males: Must agree to use one of the approved contraceptive methods from the time of Screening until completion of the Follow-up Visit.
