Further study details as provided by Amgen:

Primary Outcome Measures:
  • To evaluate the effect of AMG 745 weekly IV doses of 0.3 mg/kg, 1.0 mg/kg, or 3.0 mg/kg, compared with weekly IV placebo on thigh muscle CSA in subjects ≥ 65 yrs old with limited exercise tolerance and functional limitations [ Time Frame: 12 Weeks ]

Secondary Outcome Measures:
  • To evaluate the effect of treatment with AMG 745 on muscle strength (hand grip strength) and function (gait speed, 10-step stair climb power, chair stand and 6 minute walk distance) and to evaluate the PK of AMG 745 following multiple IV administrations [ Time Frame: 12 Weeks ]
