Brief Summary:
This is a randomized, double-blind, placebo-controlled, multiple-dose, dose-escalating study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of ACE-011 in healthy postmenopausal women.

Condition or disease Intervention/treatment Phase
Osteoporosis Biological: ACE-011 or placebo Phase 1

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Randomized, Double-Blind, Placebo-Controlled, Multiple-Dose, Dose-Escalation Study to Evaluate the Safety, Tolerability and Pharmacodynamics of ACE-011 (ActRIIA-IgG1) in Healthy Postmenopausal Women
Study Start Date : January 2008
Actual Primary Completion Date : November 2008
Actual Study Completion Date : November 2008

Arm Intervention/treatment
Experimental: single
10 subjects (8 active and 2 placebo)
Biological: ACE-011 or placebo
multiple administrations of ACE-011 given subcutaneously once per month for 3 months (4 administrations total)

Primary Outcome Measures :
  1. To evaluate the safety and tolerability of multiple, escalating doses of ACE-011 in healthy postmenopausal women. [ Time Frame: specified timepoints in the protocol ]

Secondary Outcome Measures :
  1. To estimate the pharmacokinetic (PK) parameters of multiple, escalating doses of ACE-011 administered subcutaneously and to determine the effect of ACE-011 on bone mineral density (BMD) and biochemical markers of bone formation and resorption. [ Time Frame: at specified timepoints in the protocol ]
