Brief Summary
In 2006, Weinberg proposed a hypothesis that iron accumulation was a risk factor for osteoporosis. Osteoporosis is a common complication in various diseases, such as hemochromatosis, African hemosiderosis, thalassemia, and sickle cell disease, which all share iron accumulation as a common denominator. Moreover, a 3-year retrospective longitudinal study has shown that iron accumulation was also associated with osteoporosis in healthy adults and especially that it can increase the risk of fractures in postmenopausal women. Based on these observations, iron chelation therapy may have a promising future in the treatment of iron accumulation-related osteoporosis by removing iron from the body. The purpose of this study is to determine whether the addition of the iron chelator, deferasirox, to standard therapy for postmenopausal osteoporosis, is safe and effective.

Outcome Measures
Primary Outcomes (3)
Number of participants with adverse events
An adverse event was any untoward medical occurrence in participants, and did not necessarily need to have a causal relationship with the drug in the trial. The relationship of each adverse event to study drug or the severity of each adverse event was judged by the investigator, as described below. A serious adverse event is an adverse event occurring at any dose that resulted in any of the following outcomes or actions: fatal or life-threatening; requires inpatient hospitalization; persistent or significant disability/incapacity;
12 months
Number of participants with abnormal blood pressure, heart rate, body temperature, and/or physical examination that are related to the treatment
12 months
Bone mineral density
Bone mineral density was measured by dual energy X-ray absorptiometry (DXA) scan. Percent changes in DXA Bone Mineral Density from baseline to month 6 and month 12 of the trial in all patients. Percent change from Baseline was calculated as (BMD at Month 6 or Month 12 - BMD at Baseline)/BMD at Baseline \* 100%.
Baseline, Month 6, Month 12
Secondary Outcomes (5)
Change from baseline in serum C-terminal telopeptide of type I collagen (β-CTX)
Baseline, Month 3, Month 6, Month 9 and Month 12
Change from baseline in serum N-aminoterminal prepeptide of type I procollagen (P1NP)
Baseline, Month 3, Month 6, Month 9 and Month 12
Change from baseline in serum ferritin
Baseline, Month 3, Month 6, Month 9 and Month 12
Change from baseline in blood chemistry
Baseline, Week 2, Week 4 and Month 3, Month 6, Month 9, Month 12 of the trial
Change from baseline in hematology
Baseline, Week 2, Week 4 and Month 3, Month 6, Month 9, Month 12 of the trial
Study Arms (2)
Deferasirox and calcium-vitamin D3
EXPERIMENTALDeferasirox is an orodispersible tablet and should be taken daily 30 minutes before breakfast, with a dose of 10 mg/Kg/day ± 5 mg/Kg/day during 12 month. Calcium 500 mg and Vitamin D3 800 IU should also be taken daily as a basic therapy.
Calcium-vitamin D3
PLACEBO COMPARATORCalcium 500 mg and Vitamin D3 800 IU are taken daily as a basic therapy.

Eligibility Criteria
You may qualify if:
- Lumbar spine or hip BMD T-score ≤-2.5 SD.
- Elevated serum ferritin (females: serum 500ng/ml≤ferritin≤1000ng/ml).
You may not qualify if:
- Anemia \< 10 g/dl
- Serum liver enzymes or bilirubin above the upper limit of normal at screening.
- Patients with creatinine clearance \<60 ml/min will be excluded.
- Known allergy or contraindication to the administration of Deferasirox.
- History of blood transfusion during the 6 months prior to study entry.
- Oral iron supplementation within the last 4 weeks of study entry.
- Treatment with phlebotomy within 2 weeks of screening visit.
- Patient is already taking deferasirox therapy for any reason at the time of screening.
- Patients currently or previously treated with deferiprone or Deferasirox.
- Patients with active inflammatory diseases that may interfere with the accurate measurement of serum ferritin.
- Patients with a diagnosis of a clinically relevant cataract or a previous history of clinically relevant ocular toxicity related to iron chelation.
