Outcome Measures

Primary Outcomes (3)

  • Change From Pre-dose Average in Hemoglobin (Hgb) Level to The Mid-study Average

    Change from pre-dose average was calculated by the mid-study average minus the pre-dose average. The pre-dose average was defined as the average of the 3 Hgb values that were obtained before dosing at the first screening visit, the second screening visit, and the Baseline visit; the mid-study average was defined as the average of the 2 Hgb values that were obtained at the Week 7 and Week 8 visits.

    Pre-dose (Screening, Second Screening, and Baseline), Week 7, and Week 8

  • Change From Pre-dose Average in Hgb Level to The End-of-study Average

    Change from pre-dose average was calculated by the end-of-study average minus the pre-dose average. The pre-dose average was defined as the average of the 3 Hgb values that were obtained before dosing at the first screening visit, the second screening visit, and the Baseline visit; the end-of-study average was defined as the average of the 2 Hgb values that were obtained at the Week 15 and Week 16 visits.

    Pre-dose, Week 15, and Week 16

  • Change From Mid-study Average in Hgb Level to The End-of-study Average

    Change from mid-study average was calculated by the end-of-study average minus the mid-study average. The mid-study average was defined as the average of the 2 Hgb values that were obtained at the Week 7 and Week 8 visits; the end-of-study average was defined as the average of the 2 Hgb values that were obtained at the Week 15 and Week 16 visits.

    Week 7, Week 8, Week 15, and Week 16

Secondary Outcomes (20)

  • Change From Baseline in Hgb

    Baseline, Week 4, Week 8, Week 12, and Week 16

  • Change From Baseline in Hematocrit

    Baseline, Week 4, Week 8, Week 12, and Week 16

  • Change From Baseline in Red Blood Cell (RBC) Count

    Baseline, Week 4, Week 8, Week 12, and Week 16

  • Change From Baseline in Absolute Reticulocyte Count

    Baseline, Week 4, Week 8, Week 12, and Week 16

  • Change From Baseline in Percent Reticulocyte Count

    Baseline, Week 4, Week 8, Week 12, and Week 16

  • +15 more secondary outcomes

Other Outcomes (1)

  • Mean Intravenous Iron Replacement Therapy

    Baseline, Week 8, and Week 16
