Osteoporosis, Postmenopausal
Conditions
Brief summary
The purpose(s) of this study is to measure how much of the study drug gets into the blood stream and how long it takes the body to get rid of it when given in multiple doses, subcutaneously (SC) (by inserting a needle just under the surface of the skin in the lower abdominal area), to postmenopausal (PMP) female participants. Information about any side effects that may occur will also be collected. This study will also be looking for special markers called biomarkers that can be used to study osteoporosis and/or the effects of the study drug. There will be 2 parts to this study. The first part will last approximately 6 weeks and the second part will last approximately 7 weeks.

Outcome results
Pharmacokinetics (PK): Maximum Concentration (Cmax) of Blosozumab
The mean maximum observed drug concentration of Blosozumab during 1 dosing interval was reported.
Time frame: Predose and daily up through 7 days postdose
Population: Participants who received at least 1 SC Blosozumab injection and had evaluable PK concentration data.
| Arm | Measure | Value (GEOMETRIC_MEAN) | Dispersion |
|---|---|---|---|
| Weekly SC Blosozumab Injections | Pharmacokinetics (PK): Maximum Concentration (Cmax) of Blosozumab | 59.8 picomoles per milliliter | Geometric Coefficient of Variation 54 |
PK: Area Under the Concentration Curve of Blosozumab
The mean area under the concentration of Blosozumab versus time curve during 1 dosing interval was reported.
Time frame: Predose and daily up through 7 days postdose
Population: Participants who received at least 1 SC Blosozumab injection and had evaluable PK concentration data.
| Arm | Measure | Value (GEOMETRIC_MEAN) | Dispersion |
