About this study

Official title: A Phase 3, Randomized, Double-Blind, Placebo Controlled Study of the Efficacy and Safety of Roxadustat (FG-4592) for the Treatment of Anemia in Chronic Kidney Disease Patients Not on Dialysis

The purpose of this study is to determine whether roxadustat is safe and effective in the treatment of anemia in participants with chronic kidney disease and not on dialysis.

Read the detailed description

There is a screening period of up to 6 weeks, a variable treatment period for individual participants. In order to complete the treatment period simultaneously for all study participants, the minimum treatment duration may be less than 52 weeks, with a maximum treatment duration of up to 3 years after the last participant is randomized, and a post-treatment follow-up period of 4 weeks. Participants who prematurely discontinued from treatment will be expected to complete the Early Termination (ET) and End of Study (EOS) visits. Such participants will be considered non-completers, but they will be expected to participate in long-term follow-up (LTFU) for cardiovascular events (CV) of interest, vital status, and hospitalizations until overall study closure unless the participant withdrew consent for this LTFU data collection. Participants were randomized in a 2:1 ratio to receive either roxadustat or placebo in a double-blind manner.

Study groupRoleWhat they receive
RoxadustatExperimentalParticipants will receive roxadustat tablets orally 3 times a week (TIW). The initial dose will be according to the tiered weight-based approach, with starting roxadustat doses of 70 milligrams (mg) TIW to participants weighing <70 kilograms (kg) and roxadustat doses of 100 mg TIW to participants weighing ≥70 kg. Dose-titration (up to a maximum dose of 300 mg) will be performed based upon regular measurement of Hb levels until the participant achieves central Hb value of ≥11.0 grams/deciliter (g/dL) and Hb increase from baseline (BL) of ≥1.0 g/dL at 2 consecutive study visits, separated by at least 5 days. Once target Hb level is reached, the participant will enter the maintenance period during which roxadustat dosage will be adjusted every 4 weeks to maintain participant's Hb level within the target range of 10.0 g/dL and 12.0 g/dL. The maximum treatment duration will be up to 234.9 weeks.
Receives: Drug: Roxadustat
PlaceboPlacebo comparatorParticipants will receive roxadustat-matching placebo tablets orally TIW. The initial dose will be according to the tiered weight-based approach, with starting roxadustat-matching placebo doses of 70 mg TIW to participants weighing <70 kg and roxadustat-matching placebo doses of 100 mg TIW to participants weighing ≥70 kg. Dose-titration (up to a maximum dose of 300 mg) will be performed based upon regular measurement of Hb levels until the participant achieves central Hb value of ≥11.0 g/dL and Hb increase from BL of ≥1.0 g/dL at 2 consecutive study visits, separated by at least 5 days. Once target Hb level is reached, the participant will enter the maintenance period during which roxadustat dosage will be adjusted every 4 weeks to maintain participant's Hb level within the target range of 10.0 g/dL and 12.0 g/dL. The maximum treatment duration will be up to 208.1 weeks.
Receives: Drug: Placebo

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. United States (US FDA) Submission: Mean Change From Baseline in Hb (g/dL) Over Weeks 28 to 52 Regardless of Rescue Therapy

    The change in Hb from baseline to the average level during the evaluation period (defined as Week 28 until Week 52) is reported. Hb values under the influence of a rescue therapy were not censored. The intermittent missing hemoglobin data were imputed for each treatment relying on non-missing data from all participants within each treatment group using the Monte Carlo Markov Chain (MCMC) imputation model, Monotone missing data were imputed by regression from its own treatment group. Baseline Hb was defined as the mean of up to 4 last central laboratory values prior to the first dose of study drug.

    Measured: Baseline (Day 1, Week 0), Weeks 28 to 52

  2. Ex-US Submission: Number (%) of Participants Who Achieved a Hb Response During the First 24-Weeks of Treatment Censoring for Rescue Therapy

    The number of participants who achieved a Hb response at 2 consecutive visits at least 5 days apart during the first 24 weeks of treatment, without rescue therapy (that is, red blood cell [RBC] transfusion, erythropoiesis-stimulating agent [ESA], or intravenous [IV] iron) are reported. A Hb response is defined, using central laboratory values, as the following:

    • Hb ≥11 g/dL and Hb increase from baseline by ≥1 g/dL in participants with baseline Hb >8 g/dL, or
    • An increase in Hb by ≥2 g/dL in participants with baseline Hb ≤8.0 g/dL

    Measured: Baseline up to Week 24

Secondary outcomes (10)
  1. Mean Change From Baseline in Hb Averaged Over Weeks 28 to 36 With Censoring for Rescue Therapy

    For Ex-US submission only: Hb values under the influence of a rescue therapy were censored by mixed effect model of repeated measures (MMRM) for up to 6 weeks. Baseline Hb was defined as the mean of up to 4 last central laboratory values prior to the first dose of study drug.

    Measured: Baseline (Day 1, Week 0), Weeks 28 to 36

  2. Mean Change From Baseline in Hb Averaged Over Weeks 28 to 52 Regardless of Rescue Therapy in Participants With Baseline C-Reactive Protein (CRP) >Upper Limit of Normal (ULN)

    Hb values under the influence of a rescue therapy were not censored in the analysis. The intermittent missing hemoglobin data were imputed for each treatment relying on non-missing data from all participants within each treatment group using the MCMC imputation model, Monotone missing data were imputed by regression from its own treatment group. Baseline Hb was defined as the mean of up to 4 last central laboratory values prior to the first dose of study treatment.

    Measured: Baseline (Day 1, Week 0), Weeks 28 to 52

  3. Number (%) of Participants With Hb ≥10 g/dL Averaged Over Weeks 28 to 36 With Censoring for Rescue Therapy

    Hb values under the influence of a rescue therapy were censored by Cochran-Mantel-Haenszel Test for up to 6 weeks. Responder was defined as: Hb ≥10.0 g/dL, which was based on central laboratory values.

    Measured: Weeks 28 to 36

  4. Mean Change From Baseline in Low-Density Lipoprotein (LDL) Cholesterol Averaged Over Weeks 12 to 28

    Baseline LDL cholesterol was defined as the last LDL cholesterol value prior to the first dose of study drug.

    Measured: Baseline (Day 1, Week 0), Weeks 12 to 28

  5. Rate of Change in eGFR From Baseline up to 12 Months (Linear Random Coefficient Model With Observed Data)

    Progression of chronic kidney disease was measured by rate of change in eGFR over time adjusted by baseline eGFR, with censoring for chronic dialysis or kidney transplant, using random slope and intercept model. Least Square Mean of change from baseline at 1 year was derived based on a random slopes and intercepts model using all available eGFR values (1 baseline and all post-treatment values up to end of treatment period + 7 days or start of dialysis) adjusted on treatment, baseline Hb, baseline eGFR, geographical region, cardiovascular events history at Baseline (yes vs. no), time (continuous value), the interaction terms of baseline eGFR by time, baseline Hb by time, and treatment by time as fixed effects, with random effects of intercept and linear slope of time. All assessments collected after the start of stable dialysis or kidney transplant were excluded from the analysis.

    Measured: Baseline, Month 12

  6. Number of Participants Who Received Blood/RBC Transfusion in the First 52 Weeks of Treatment

    Participants with any use of blood/RBC transfusion were reported.

    Measured: Baseline up to Week 52

  7. Number (%) of Participants Who Received Rescue Therapy in the First 24 Weeks and in the First 52 Weeks of Treatment

    Rescue therapy included any use of RBC transfusion, ESA, or IV iron.

    Measured: Baseline (Day 1, Week 0) up to Week 24 and up to Week 52

  8. Change From Baseline in Short Form 36 (SF-36) Version 2 Physical Functioning Subscore and Vitality Subscore at Weeks 12 to 28

    The SF-36 V2 consists of 36 questions covering 8 health domains: physical functioning, bodily pain, role limitations due to physical problems, role limitations due to emotional problems, general health perceptions, mental health, social function, and vitality. The physical functioning subscore and vitality subscore are reported. The scores ranged from 0 (worst) to 100 (Best). A higher score indicates a general improvement of life quality or well-being. Baseline score was defined as the last physical functioning value or vitality value, as applicable, prior to the first dose of study drug.

    Measured: Baseline (Day 1, Week 0), Weeks 12 to 28

  9. Number (%) of Participants Who Experienced Exacerbation of Hypertension

    Exacerbation of hypertension was defined as an increase from baseline of ≥20 millimeter of mercury (mmHg) in systolic blood pressure (sBP) and sBP ≥170 mmHg or an increase from baseline of ≥15 mmHg in diastolic blood pressure (dBP) and dBP ≥110 mmHg.

    Measured: Baseline up to Week 52

  10. Mean Change From Baseline in Mean Arterial Pressure (MAP) Averaged Over Weeks 20 to 28

    Baseline MAP was defined as the last MAP value prior to the first dose of study drug.

    Measured: Baseline, Weeks 20 to 28
