Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase 3, Randomized, Double-Blind, Placebo Controlled Study of the Efficacy and Safety of FG-4592 for the Treatment of Anemia in Chronic Kidney Disease Patients Not on Dialysis

Further study details as provided by FibroGen:

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

  • 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)

  • 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)

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

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

Estimated Enrollment: 900
Study Start Date: November 2012
Estimated Study Completion Date: March 2018
Estimated Primary Completion Date: March 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: FG-4592 (Double-blind, Three times a week)
Weight-based starting doses of 70mg or 100mg; dose adjustments to hemoglobin levels are allowed during the study.
Drug: FG-4592
Other Name: Roxadustat; ASP1517; AZD9941
Placebo Comparator: Placebo (Double-blind, Three times a week)
Weight-based starting doses of 70mg or 100mg; dose adjustments to hemoglobin levels are allowed during the study.
Drug: Placebo
Other Name: Roxadustat; ASP1517; AZD9941

Detailed Description:
There is a screening period of up to 6 weeks, a variable treatment period for individual subjects with a minimum treatment duration of 52 weeks and a maximum treatment duration of time to enroll all subjects plus 52 weeks after the last subject is randomized, and a post-treatment follow-up period of 4 weeks. A total of 600 patients will be randomized in a 2:1 ratio to receive either roxadustat (FG-4592-approximately 400 subjects) or placebo (approximately 200 subjects) in a double-blind manner.
