  Purpose
This study will evaluate the impact of investigator and patient education and educational materials to foster calcium and vitamin D supplementation to mitigate the potential for hypocalcemia post Reclast® administration in patients with Paget's disease of bone.

Condition Intervention Phase
Paget's Disease of the Bone Hypocalcemia Drug: Reclast (ZOL446, zoledronic acid) Dietary Supplement: Calcium Dietary Supplement: Vitamin D Phase 4

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Post US Approval Voluntary Registry Study to Determine Incidence of Hypocalcemia Post Reclast® Treatment in Patients With Paget's Disease After Institution of Educational Strategies to Improve Adherence to Calcium and Vitamin D Supplementation

Primary Outcome Measures:
  • Percentage of Patients With Serum Calcium <2.07 mmol/L at 9-11 Days After Receiving Zoledronic Acid. [ Time Frame: at Visit 2 (days 9 - 11 post-infusion), visit 3 (day 30) ]
    To be included in the analysis, patients were required to have a baseline serum calcium of at least 2.07 mmol/L and at least one serum calcium measurement 9-11 days post-infusion of zoledronic acid. In case of multiple assessments, for baseline visit the last measurement prior to the first dose was used in the analysis, and for Visits 2 and 3, the lowest serum calcium in the visit window was used. hypocalcemia was defined as treatment-emergent serum calcium <2.07 mmol/L at 9-11 days after the study drug infusion.


Secondary Outcome Measures:
  • Change From Baseline in Serum Calcium (mmol/L) - Safety Population [ Time Frame: Baseline, Visit 2 (days 9 - 11 post-infusion), visit 3 (day 30) ]
    Change from baseline = endpoint - baseline, at each time point, only participants with a value at baseline and that time point are included in the change from baseline column. In case of multiple assessments, for baseline visit the last measurement prior to the first dose was used in the analysis, and for Visits 2 and 3, the lowest serum calcium in the visit window was used.

  • Percentage of Newly Occurring Post-baseline Hypocalcemia Symptoms Based on Hypocalcemia Questionnaire at End of Study Visit 2 or Visit 3 (Safety Population) [ Time Frame: End of study: Visit 2 (days 9 - 11 post-infusion) or visit 3 (day 30) ]
    The end of study is not a separate time point. It is the last post-baseline, for majority the end of study was visit 2. There were 2 patients who had the end of study at Visit 3. If calcium at visit 2 was abnormal it was measured again at visit 3.

Dietary Supplement: Calcium
1500 mg elemental calcium daily in divided doses (the divided doses were 2-3 times per day depending on the formulation)
Dietary Supplement: Vitamin D
800 IU vitamin D daily, particularly in the immediate 2 weeks following zoledronic acid administration
