Inclusion Criteria
- •Participant has provided informed consent prior to initiation of any study-specific activities/procedures.
- •Male and female participants aged ≥ 18 years at the time of signing the informed consent.
- •Participants are receiving glucocorticoid treatment at screening.
- •Participants who are ≥ 50 years of age at the time of screening will be required to have a T-score with:
- •- a BMD value equivalent to a T-score ≤ -2.5 at the lumbar spine or total hip or femoral neck; OR
- •- a BMD value equivalent to a T-score ≤ -1.0 at the lumbar spine or total hip or femoral neck AND a history of osteoporotic fracture.
- •Participants who are < 50 years of age at the time of screening will be required to have a T-score with a BMD value equivalent to a T-score ≤ -1.0 at the lumbar spine or total hip or femoral neck AND have a history of osteoporotic fracture.
- •At least 2 lumbar vertebrae from L1 through L4 and 1 hip must be evaluable by dual-energy x-ray absorptiometry (DXA).

- •Coagulation function:
- •1 Prothrombin time (PT)/international normalized ratio (INR) and partial thromboplastin time or activated partial thromboplastin time ≤ 1.5 x upper limit of normal (ULN). Participants on chronic anticoagulation therapy who do not meet the criteria above may be eligible to enroll at the investigator's discretion per local standard of care.

- •any active infection for which systemic anti-infectives were used within 4 weeks prior to screening
- •a serious infection, defined as requiring hospitalization or intravenous anti-infectives within 8 weeks prior to screening
- •recurrent or chronic infections or other active infection that, in the opinion of the investigator, might compromise the safety of the participant.

Other investigational procedures while participating in this study are excluded.
- •Diagnostic Assessments
- •Abnormalities of the following per central laboratory reference ranges:
- •- Vitamin D deficiency (25[OH] vitamin D level < 20 ng/mL [< 49.9 nmol/L]). Vitamin D replenishment will be permitted, and participants may be re-screened once.
