    Change in mean hemoglobin concentration between baseline and Visit 14 to 17 at each dose level. Baseline hemoglobin value is the mean of three consecutive hemoglobin concentrations with the last hemoglobin concentration done within the 7 days prior to randomization and the value obtained on the day of randomization. Visit 14 to 17 hemoglobin value is a mean of hemoglobin concentrations from Day 99 [Visit 14] to Day 113 [Visit 17].

    Change in mean hemoglobin concentration between baseline and Visit 14 to 17 at each dose level for participants not rescued prior to Day 115. Baseline hemoglobin value is the mean of three consecutive hemoglobin concentrations with the last hemoglobin concentration done within the 7 days prior to randomization and the value obtained on the day of randomization. Visit 14 to 17 hemoglobin value is a mean of hemoglobin concentrations from Day 99 [Visit 14] to Day 113 [Visit 17].

  4. Number of Participants With Adverse Events (AEs)

    Time frame: From date of first dose of investigational product to 112 days after the last dose or until the last study visit, whichever period was longer. The maximum duration for any IV or SC dose was 114 days. Up to approximately 226 days.

    Treatment-emergent adverse event (TEAE) was defined as an adverse event with start date on or after date of first dose of study drug. An AE is any noxious, unintended, or untoward medical occurrence that may appear or worsen in a participants during the course of a study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the participant's health, including laboratory test values, regardless of etiology. A serious adverse event is defined as any AE which results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; constitutes an important medical event. Severity and intensity was assessed using the following grading scale: Mild, Moderate and Severe (could be non-serious or serious).
