Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: DOUBLE

Study Groups

B

Six female subjects in each of cohorts 1 to 5 will receive AMG 167; six male subjects in each of cohorts 6 and 8; three female subjects in each of cohorts 7 and 9.

Group Type: ACTIVE_COMPARATOR

Placebo

Intervention Type: DRUG

Subjects will be randomized to receive 1 of 5 doses of AMG 167 or equivalent volume of placebo administered as a single dose. Postmenopausal women will receive AMG 167 in fixed doses of 21 mg, 70, 210, 350, or 700 mg SC (under the skin), or 70 mg or 350 mg IV (in the vein), while men will receive doses of 70 mg or 350 mg SC or IV.

A

Two female subjects in each of cohorts 1 to 5 will receive placebo; two male subjects in each of cohorts 6 and 8; and 1 female subject in each of cohorts 7 and 9.
