Pyrenees: Roxadustat in the Treatment of Anemia in End Stage Renal Disease (ESRD) Patients on Stable Dialysis
Study Details
Study Description
Brief Summary
This study was conducted to explore a new therapy for anemia in participants with end stage renal disease (ESRD) on dialysis. Anemia is a reduced number of red blood cells or hemoglobin. Hemoglobin (which contains iron) is important for the transport of oxygen in your blood. The purpose of this study was to evaluate if roxadustat is effective and safe in the maintenance treatment of anemia in ESRD participants on stable dialysis. Roxadustat was compared to epoetin alfa and darbepoetin alfa, commercially available medicines for treatment of anemia.

Experimental: Roxadustat Participants received roxadustat three times a week (TIW) for at least 52 weeks up to a maximum of 104 weeks. Participants received initial dose of roxadustat in doses of 100 mg, 150 mg or 200 mg, according to the average weekly dose of epoetin or darbepoetin alfa prior to randomization. Participants' roxadustat dosage was adjusted every 4 weeks to maintain Hb level within the target range 10.0 to 12.0 g/dL. Dose adjustment steps were as follows: 20, 40, 50, 70, 100, 150, 200, 250, 300, and 400 mg. Oral iron treatment of 200 mg was allowed for supplementation to support erythropoiesis. Treatment with intravenous iron was allowed only if certain protocol criteria were met. |
Drug: Roxadustat
Participants received initial dose of roxadustat orally as a tablet in doses of 100 mg, 150 mg or 200 mg, according to the average weekly dose of epoetin or darbepoetin alfa prior to randomization. Participants' roxadustat dosage was adjusted every 4 weeks to maintain Hb level within the target range 10.0 to 12.0 g/dL. Dose adjustment steps were as follows: 20, 40, 50, 70, 100, 150, 200, 250, 300, and 400 mg. Oral iron treatment of 200 mg was allowed for supplementation to support erythropoiesis. Treatment with intravenous iron was allowed only if certain protocol criteria were met.
Other Names:
Drug: Iron
Oral iron treatment was recommended for supplementation to support erythropoiesis and as first-line treatment for iron deficiency, unless participant was intolerant to this treatment. For participants receiving roxadustat the recommended daily dose was 200 mg of elemental iron. Participants were advised to take roxadustat at least 1 hour before or 1 hour after oral iron. Intravenous iron supplementation for participants receiving roxadustat was allowed if all of the following criteria were met: The participant's Hb level had not responded adequately to roxadustat following two consecutive dose increases or reached the maximum dose limit, and participant's ferritin was < 100 ng/mL (< 220 pmol/L) or TSAT < 20%, or the participant was intolerant of oral iron therapy. For participants treated with epoetin alfa or darbepoetin alfa, IV iron supplementation was given according to standard of care.

Study Results
Participant Flow
Recruitment Details | Study population consisted of participants with end-stage renal disease (ESRD) who were on stable hemodialysis (HD) or peritoneal dialysis (PD), and were also on stable treatment with epoetin (i.e. epoetin alfa, beta, theta, zeta, delta or omega) or darbepoetin alfa for anemia. |
---|---|
Pre-assignment Detail | Participants were randomized in a 1:1 ratio to roxadustat or ESA (epoetin alfa or darbepoetin alfa). Randomization was stratified by 5 factors: previous ESA treatment, region, history of cardiovascular, cerebrovascular or thromboembolic diseases, average weekly ESA dose 4 weeks prior to randomization and the screening hemaglobin (Hb) value. |
Arm/Group Title | Roxadustat | ESA (Erythropoiesis-Stimulating Agent) |
---|---|---|
Arm/Group Description | Participants received roxadustat three times a week (TIW) for at least 52 weeks up to a maximum of 104 weeks. Participants received initial dose of roxadustat in doses of 100 mg, 150 mg or 200 mg, according to the average weekly dose of epoetin or darbepoetin alfa prior to randomization. Participants' roxadustat dosage was adjusted every 4 weeks to maintain Hb level within the target range 10.0 to 12.0 g/dL. Dose adjustment steps were as follows: 20, 40, 50, 70, 100, 150, 200, 250, 300, and 400 mg. Oral iron treatment of 200 mg was allowed for supplementation to support erythropoiesis. Treatment with intravenous iron was allowed only if certain protocol criteria were met. | Participants received epoetin alfa once weekly, twice weekly or TIW and darbepoetin alfa once a week or once every other week. Participants were treated for at least 52 weeks up to a maximum of 104 weeks. Treatment dosage was adjusted according to the pre-specified rule of keeping the participant's Hb levels between 10.0 to 12.0 g/dL. Participants were not allowed to switch from epoetin alfa to darbepoetin alfa or vice versa. |

Outcome Measures
Title | Change From Baseline (BL) to the Average Hemoglobin (Hb) in Weeks 28-36 Without Rescue Therapy [EU (EMA)] |
---|---|
Description | Baseline Hb was defined as the mean of four central laboratory Hb values; four latest Hb values prior or on the same date as the first study drug intake. For participants who did not have an available Hb value during the week 28-36 period, imputation rules were applied. For analyses without rescue therapy, participants who used rescue therapy after the initiation of rescue therapy were set to missing for 6 weeks from the start date of rescue therapy. If no Hb value was available, an imputation technique was used, with the mean of all available values from Day 1 to minimum (End of Efficacy Emergent Period) carried forward. |

Title | Time to First Use of Rescue Therapy |
---|---|
Description | Rescue therapy was defined as red blood cell (RBC) transfusion for both treatment groups and ESA for roxadustat participants. Only rescue medication that was started during the study treatment and up to end of efficacy emergent period was taken into account and considered as use of rescue medication. For participants who have experienced more than one use of rescue therapy, only their first event following study treatment was used. Data reported was analyzed by Kaplan-Meier estimate for cumulative proportion and the 95% confidence interval was calculated with Greenwood's formula. |

Participants received initial dose of roxadustat in doses of 100 mg, 150 mg or 200 mg, according to the average weekly dose of epoetin or darbepoetin alfa prior to randomization. Participants' roxadustat dosage was adjusted every 4 weeks to maintain Hb level within the target range 10.0 to 12.0 g/dL. Dose adjustment steps were as follows: 20, 40, 50, 70, 100, 150, 200, 250, 300, and 400 mg. Oral iron treatment of 200 mg was allowed for supplementation to support erythropoiesis. Treatment with intravenous iron was allowed only if certain protocol criteria were met. | Participants received epoetin alfa once weekly, twice weekly or TIW and darbepoetin alfa once a week or once every other week. Participants were treated for at least 52 weeks up to a maximum of 104 weeks. Treatment dosage was adjusted according to the pre-specified rule of keeping the participant's Hb levels between 10.0 to 12.0 g/dL. Participants were not allowed to switch from epoetin alfa to darbepoetin alfa or vice versa. |

Title | Change From BL to the Average of Weeks 12 to 28 in SF-36 Physical Component Score (PCS) |
---|---|
Description | Baseline SF-36 PCS was defined as the SF-36 PCS value on Day 1. SF-36 contains 36-item that measures 8 scales with scores ranging from 0-100: physical functioning (PF); role limitations due to physical health problems (RP); bodily pain (BP); social functioning (SF); general health perceptions (GH); role limitations due to emotional problems (RE); vitality, energy or fatigue (VT); and mental health (MH). These scores are normed to the US population (norm-based scoring had very little impact on results when data was collected in Western European countries) to have a mean of 50 and standard deviation of 10. The PCS was calculated based on all 8 scales and ranges from 5.02-79.78. For each of these above scales, higher scores always indicating better health status. |

Arm/Group Description | Participants received roxadustat three times a week (TIW) for at least 52 weeks up to a maximum of 104 weeks. Participants received initial dose of roxadustat in doses of 100 mg, 150 mg or 200 mg, according to the average weekly dose of epoetin or darbepoetin alfa prior to randomization. Participants' roxadustat dosage was adjusted every 4 weeks to maintain Hb level within the target range 10.0 to 12.0 g/dL. Dose adjustment steps were as follows: 20, 40, 50, 70, 100, 150, 200, 250, 300, and 400 mg. Oral iron treatment of 200 mg was allowed for supplementation to support erythropoiesis. Treatment with intravenous iron was allowed only if certain protocol criteria were met. | Participants received epoetin alfa once weekly, twice weekly or TIW and darbepoetin alfa once a week or once every other week. Participants were treated for at least 52 weeks up to a maximum of 104 weeks. Treatment dosage was adjusted according to the pre-specified rule of keeping the participant's Hb levels between 10.0 to 12.0 g/dL. Participants were not allowed to switch from epoetin alfa to darbepoetin alfa or vice versa. |
