Trial overview
Official title: A 24-week, Phase III, open-label, non-comparative, multi-center study to evaluate efficacy and safety of GSK1278863 in Japanese hemodialysis subjects with anemia associated with chronic kidney disease who are not taking erythropoiesis stimulating agents
Trial description: This 24-week, Phase 3, open-label, non-comparative, multicentre study aims to evaluate the efficacy and safety of GSK1278863 in Japanese hemodialysis (HD) patients with renal anemia not using erythropoiesis-stimulating agents (ESAs). The primary objective is to evaluate the initial response to GSK1278863 measured by hemoglobin (Hgb) levels in HD patients not using ESAs enrolled in this study. The study is designed to evaluate the appropriateness of the starting dose of GSK1278863 and of the GSK1278863 dose adjustment regimen to achieve or maintain the target Hgb levels. This study will consist of a 4-week screening period, a 24-week treatment period (4-week fixed-dose period and a 20-week dose adjustment period), and a 2- to 4-week follow-up period.

No
- Age (at the time of informed consent): >=20 years
- Dialysis: Patients on hemodialysis (HD) or hemodiafiltration (HDF)
- CKD related criteria
- Kidney transplant: Planned living kidney transplant during the study period
Inclusion and exclusion criteria
Inclusion criteria:
- Age (at the time of informed consent): >=20 years
- Dialysis: Patients on hemodialysis (HD) or hemodiafiltration (HDF)
- Use of any erythropoiesis stimulating agent (ESA): Newly started dialysis (Dialysis newly started <12 weeks before screening): Patients not using ESAs after the start of dialysis; Maintenance dialysis (Dialysis started >=12 weeks before screening): Patients not using ESAs within 8 weeks before screening (including interruption of ESA therapy)
- Hemoglobin (Hgb): >=8.0 to <10.0 g/dL (measured using a point-of-care Hgb measurement device at the study site on Day 1)
- Iron parameter: Ferritin >100 nanograms (ng)/milliliter (mL) or transferrin saturation (TSAT) >20% (at screening only)
