Study to Evaluate Effect of Intranasal Teriparatide on Serum P1NP, a Biomarker of Bone Formation, in Postmenopausal Women With Low Bone Mass

A Parallel Group Study to Evaluate the Effect of Six Weeks of Treatment With Nasal Spray (NS) ZT-034, Compared to Subcutaneous (SC) Forteo and Placebo, on Bone Formation, as Assessed by Stimulation of Serum P1NP Levels in Postmenopausal Women With Low Bone Mass

This study is being conducted to evaluate the effect treatment has on serum P1NP levels, a biomarker of bone formation in postmenopausal women with low bone mass.

Inclusion Criteria:

• Postmenopausal Females Age ≥ 45 years.
• Weight > 45 kg and < 90 kg

• Low bone mass at lumbar spine, total hip or femoral neck (BMD T-score of ≤ - 1.5 or lower) or a recent (within 5 years of baseline) history of fragility fracture (excluding fractures of hands, feet, face and/or skull) and a T-score of -1.0 or lower at lumbar spine, total hip or femoral neck

Exclusion Criteria:

• Serious Medical Condition
• History of diseases which affect bone metabolism other than postmenopausal osteoporosis such as Paget's disease, any secondary causes of osteoporosis, hypoparathyroidism, or hyperparathyroidism
• Have a history of cancer within the past 5 years, except for basal cell carcinoma
• Have hypocalcemia or hypercalcemia from any cause or have a recent history of kidney stones or pre-existing hypercalciuria;
