Phase III Study of GSK1278863 in Japanese Non-dialysis (ND) and Peritoneal Dialysis (PD) Subjects With Renal Anemia

27 april 2021 bijgewerkt door: GlaxoSmithKline

A 52-week, Phase III, Open-label, Multi-center Study to Evaluate Efficacy and Safety of GSK1278863 in Japanese Non-dialysis and Peritoneal Dialysis Subjects With Anemia Associated With Chronic Kidney Disease

This is a Phase III, open-label, active-controlled, parallel-group, multi-center study to compare the efficacy and safety of GSK1278863 administered for 52 weeks versus epoetin beta pegol in approximately 286 Japanese ND and 50 PD subjects with renal anemia. The study will consist of three cohorts. Cohort 1 and Cohort 3 will consist of ND subjects (Erythropoiesis-Stimulating Agent [ESA] users and ESA non-users) randomized to receive GSK1278863 or epoetin beta pegol in a ratio of 1:1. PD subjects will be enrolled into Cohort 2 and will receive GSK1278863. This study consists of a 4-week screening phase, a 52-week treatment phase (including primary efficacy evaluation period [Weeks 40 to 52]), and a 4-week follow-up phase following the treatment phase. The primary objective of this study is to demonstrate non-inferiority of GSK1278863 to epoetin beta pegol based on mean hemoglobin (Hgb) during the primary efficacy evaluation period in ND subjects. ESA non-users from Cohort 1 will be excluded from the primary efficacy analysis. Study results will be used as pivotal study data for an NDA submitted for GSK1278863 for the treatment of renal anemia in Japan.

  • Iron: Planned use of intravenous iron during the screening phase or during a period from Day 1 to Week 4 Note: Oral iron is acceptable. However, the same dose regimen must be used throughout the screening phase and from Day 1 to Week 4.

General health-related criteria

  • Other conditions: Any other condition, clinical or laboratory abnormality, or examination finding that the investigator (or subinvestigator) considers would put the subject at unacceptable risk, which may affect study compliance or prevent understanding of the aims or investigational procedures or possible consequences of the study.

Change from Baseline in Ferritin in ND participants was summarized at each assessment visit. The Baseline value was the latest pre-dose assessment (Day 1 pre-dose).

Area Under the Concentration-time Curve From Time Zero Extrapolated to 4 Hours (AUC[0-4]) of Daprodustat for All Dose Levels in ND and PD Participants
Tijdsspanne: 1, 2, 3 and 4 hours post dose at Weeks 12 and 24
Blood samples were collected at indicated timepoints. Pharmacokinetic (PK) parameters of Daprodustat were calculated using non-compartmental method. AUC (0-4) is presented for combined Week 12 and 24. Geometric mean and geometric coefficient of variation is presented. NA indicates that the data is not available since geometric coefficient of variation could not be calculated for a single participant.
