Primary Outcome Measures:
  • Hemoglobin response to treatment using various FG-4592 dosing regimens. [ Time Frame: Change from Baseline hemoglobin to 24 weeks ] [ Designated as safety issue: No ]
    Cumulative number (%) of subjects with hemoglobin greater than or equal to 11g/dL and increase of greater than or equal to 1 g/dL from baseline up to 24 weeks.

Secondary Outcome Measures:
  • Hemoglobin maintenance once correction is achieved. [ Time Frame: Week 28-36 ] [ Designated as safety issue: No ]
    Mean change in Hb averaged over 8 weeks of treatment at Weeks 28-36, without rescue therapy within 6 weeks prior to and during this 8 week evaluation period.

  • Average monthly IV iron use per subject [ Time Frame: Weeks 1 up to 156 weeks. ] [ Designated as safety issue: No ]
    Average monthly IV iron use per subject

  • Mean change in low-density lipoprotein (LDL) cholesterol [ Time Frame: Weeks 12-24 ] [ Designated as safety issue: No ]
  • Cumulative number (%) of patients with with exacerbation of hypertension. [ Time Frame: Change in blood pressure from baseline up to weeks 156. ] [ Designated as safety issue: Yes ]
    At least one of the following criteria must be met in order to be considered an exacerbation of hypertension: an increase in anti-hypertensive medication use; an adverse event of hypertension or an increase in blood-pressure from baseline confirmed by repeat measurement.

  • Time to achieve Hemoglobin response [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: No ]
    Time to achieve first Hb response as defined by the primary endpoint.

  • Change in the Health-related quality of life (HRQoL) [ Time Frame: Weeks 12, 28 and 52. ] [ Designated as safety issue: No ]
    Health-related quality of life (HRQoL) will be assessed using the SF-36, vitality and physical functioning subscales. Both within-treatment and between-treatment effect will be assessed.

Estimated Enrollment: 750
Study Start Date: December 2013
Estimated Study Completion Date: October 2016
Estimated Primary Completion Date: May 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: FG-4592 (Roxadustat)
FG-4592 (Roxadustat) will be dosed orally three times a week. The initial dose is based on weight. Thereafter, dosages will be adjusted based on Hb values and rate of change compared to previous Hb values.
Drug: FG-4592
Other Name: Roxadustat
Active Comparator: Epoetin alfa
Epoetin alfa will be dispensed per the package insert or the country-specific product labeling.
Drug: Epoetin Alfa
Other Name: Procrit, Epogen

Detailed Description:

There is a screening period of up to 6 weeks, a treatment period of a minimum of 52 weeks and a maximum of approximately 3 years after last patient is randomized, and a post-treatment follow-up period of 4 weeks. A total of up to 750 patients will be randomized in a 1:1 ratio to receive either open-label FG-4592 or Active Control (Epoetin alfa).
