Study Description
Brief Summary:
The purpose of this study is to determine whether FG-4592 is safe and effective in the treatment of anemia in chronic kidney disease patients who are not on dialysis.

Condition or disease Intervention/treatment Phase
CKD Anemia Drug: FG-4592 Drug: Placebo Phase 3

Detailed Description:
There is a screening period of up to 6 weeks, a variable treatment period for individual subjects. In order to complete the treatment period simultaneously for all study subjects, the minimum treatment duration may be less than 52 weeks, with a maximum treatment duration of up to 3 years after the last subject is randomized, and a post-treatment follow-up period of 4 weeks. Subjects were randomized in a 2:1 ratio to receive either roxadustat (FG-4592) or placebo in a double-blind manner.

Outcome Measures

Primary Outcome Measures :
  1. Efficacy of roxadustat (FG-4592) for the treatment of anemia correction and maintenance [ Time Frame: 52 weeks ]
    Efficacy of roxadustat (FG-4592) in achieving hemoglobin correction and maintenance (as defined in protocol) in CKD subjects not on dialysis

Secondary Outcome Measures :
  1. Effect of roxadustat (FG-4592) on serum lipid parameters [ Time Frame: 28 weeks ]
    Change in low-density lipoprotein (LDL) cholesterol.

  2. Effect of roxadustat (FG-4592) on patient reported outcomes [ Time Frame: 28 weeks ]
    Evaluate health-related quality of life benefits, as measured by the 36-Item Short Form Health Survey (SF-36)

  3. Evaluate the need for anemia rescue therapy, such as IV Iron, blood transfusion or injectable ESA [ Time Frame: 52 weeks ]
    Proportion of patients who received rescue therapy (composite of RBC transfusion, ESA use, and IV iron)

  4. Effect of roxadustat (FG-4592) on blood pressure [ Time Frame: 52 weeks ]
    Change in mean arterial pressure and effect on reducing hypertension

  5. Safety of roxadustat (FG-4592) [ Time Frame: Minimum of 52 weeks ]
    Adverse events, serious adverse events, vital signs, electrocardiograms and physical exams
