Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Part B will be an investigation of bone mineral density (BMD) at the lumbar spine and BMD and bone turnover at the femoral neck, total hip, and total body. Part B will consist of a subgroup of subjects enrolled in Part A (i.e., subjects that meet all of Part A inclusion criteria and none of Part A AND Part B exclusion criteria) who are 18 to 45 years of age (inclusive at the time of screening). BMD will be assessed by dual-energy X-ray absorptiometry (DXA) scan.
The study duration (Parts A and B) for each subject will be up to approximately 404 days (28 days \[screening\] + 376 days \[Treatment and Follow-up Period\]), unless the subject meets criteria for the extended Part B Follow-up, in which the duration will be approximately 769 days (28 days \[screening\] + 376 days \[Treatment and Follow-up Period\] + 365 days \[extended Part B Follow up\]).
