|Official Title:||Open Label Proof of Concept Study of IV Zoledronic Acid (ZA) 5 mg After Forteo in Postmenopausal Women|
- Change in Lumbar Spine BMD (Bone Mineral Density) in g/cm^2 From Baseline to Month 12 Relative to Baseline as Measured by DXA (Dual-energy X-ray Absorptiometry) [ Time Frame: Baseline and 12 months ]
- Change in Bone Density (Grams/cm^2) at the Total Hip at 6 and 12 Months [ Time Frame: 6 months and 12 months ]Change in bone density (grams/cm^2) at the total hip at 6 and 12 months. 12 month reported based on usual interval for bone density follow-up in clinical practice.
- Change in Serum C-telopeptide Type 1 Collagen (CTX) (at Day 10 and Months 2, 6, 9 and 12) [ Time Frame: 12 months ]Change in serum c-telopeptide type 1 collagen (CTX) (at day 10 and months 2, 6, 9 and 12. 12 month values reported based on 12 month duraton of zolendronic acid effect.
- Change in Serum N-propeptide Type 1 Collagen (P1NP) (at Day 10 and Months 2, 6, 9 and 12) [ Time Frame: 12 months ]Change in serum n-propeptide type 1 collagen (P1NP) (at day 10 and months 2, 6, 9 and 12. 12 month values reported based on 12 month duraton of zolendronic acid effect.

This will be a single center open label proof of concept study, recruiting subjects previously treated with Forteo for at least 12 months.
A screening period of 3 to 6 weeks will precede the treatment period. At the baseline visit, patients whose eligibility is confirmed will be treated with ZA and followed for 12 months. Safety and efficacy will be assessed at regular intervals (day one, day 10, month 2, month 6, month 9 and month 12). Renal safety will be assessed prior to the i.v. dose of study medication, day 10 after the i.v. dose of study medication and at 12 months. Bone density at the lumbar spine (L1-4) and total hip will be performed at 6 months and at the end of the 12 month treatment period. Biomarker analyses for secondary endpoint will be performed for at day 10, month 2, month 6, month 9 and month 12.
