Primary Outcome Measures:
  • Pharmacokinetics (Cmax) [ Time Frame: 28 days ] [ Designated as safety issue: No ]
    Maximum observed concentration in serum

  • Pharmacokinetics (Tmax) [ Time Frame: 28 days ] [ Designated as safety issue: No ]
    Time to maximum concentration

  • Pharmacokinetics (AUC 28d) [ Time Frame: 28 days ] [ Designated as safety issue: No ]
    Area under the concentration-time curve

  • Pharmacokinetics (t1/2,z) [ Time Frame: 211 days ] [ Designated as safety issue: No ]
    Terminal half life

  • Adverse Event [ Time Frame: 211 days ] [ Designated as safety issue: Yes ]
    treatment emergent adverse sevents (TEAEs) and number of subjects with TEAEs.

Secondary Outcome Measures:
  • Efficacy [ Time Frame: 113 days ] [ Designated as safety issue: No ]
    Change in mean hemoglobin concentration between baseline and day 113

  • Bone Turnover [ Time Frame: 211 days ] [ Designated as safety issue: No ]
    Change in serum bone biomarker concentrations between baseline and end of study (day 211)

Study Start Date: October 2013
Estimated Study Completion Date: October 2015
Estimated Primary Completion Date: September 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Intravenous Dose Group 1, 2, and 3
Intravenous Dose Group 1 starting at 0.1 mg/kg and escalated in Dose Groups 2 (0.2 mg/kg) and Dose Group 3 (0.3 mg/kg) administered every 14 days
Biological: Sotatercept
Sotatercept is dosed intravenously every 14 days. The dose a subject receives will depend on the randomization arm and the dose group.
Other Name: ACE-011
Experimental: Subcutaneous Dose Group 1, 2, and 3
Subcutaneous Dose Group 1 starting at 0.13 mg/kg and escalated in Dose Groups 2 (0.26 mg/kg) and Dose Group 3 (0.4 mg/kg), administered every14 days
Biological: Sotatercept
Sotatercept is dosed subcutaneously every 14 days. The dose a subject receives will depend on the randomization arm and the dose group.
Other Name: ACE-011
