NCT04338529

Brief Summary

Discontinuation of denosumab results in a rebound response of bone turnover markers, which rise above baseline at 3 months and remain elevated until reaching again baseline levels approximately 30 months after the last dose. Bone mineral density (BMD) gains are also lost and BMD values reach original baseline values after 1-2 years off-treatment.For the above reasons, current literature recommends that patients who discontinue denosumab should continue to receive either intravenous (iv) or oral (peros) bisphosphonate therapy for some time. The study aims to investigate changes in the BMD of the lumbar spine 12 months after transitioning from denosumab to oral alendronate 70 mg in a weekly effervescent tablet formulation

    12 months

Secondary Outcomes (5)

  • Bone Mineral Density FN

    12 months

  • Serum levels of bone turnover markers (BTMs): P1NP, CTX and TRAP5b

Study Arms (2)

Group Alendronate 6m

Postmenopausal Caucasian women who were treated with denosumab and became osteopenic (BMD T-score of \> -2.5 at the LS and the non-dominant FN) and were assigned from their treating physician to receive treatment with alendronate in an effervescent tablet formulation for 6 months and then followed for another 6 months without medication. In case serum P1NP levels are \> 35μg/L and/or serum CTX levels are \> 280 ng/L at 9 months (3 months following alendronate discontinuation) the patients would be strongly advised to restart alendronate treatment.

Drug: Binosto 70Mg Effervescent Tablet

Group Alendronate 12m

Postmenopausal Caucasian women who were treated with denosumab and became osteopenic (BMD T-score of \> -2.5 at the LS and the non-dominant FN) and were assigned from their treating physician to receive treatment with alendronate in an effervescent tablet formulation for 12 months.

Study Population

The study will include postmenopausal Caucasian women who were treated with denosumab and became osteopenic (BMD T-score of \> -2.5 at the LS and the non-dominant FN) and were assigned from their treating physician to receive treatment with alendronate in an effervescent tablet formulation for either 6 months (Group 6, n=46) and then followed for another 6 months without medication, or 12 months of continuous treatment with alendronate (Group 12, n=46). As this is an observational study, patients could be either referred from their treating physicians or could be actually followed by the investigators themselves in case the investigator is the treating physician

You may qualify if:

  • i) osteopenic postmenopausal Caucasian women following Dmab treatment ii) assignment to treatment with alendronate in an effervescent tablet formulation following Dmab discontinuation

You may not qualify if:

  • i) secondary osteoporosis; ii) diseases that could affect bone metabolism iii) medications that could affect bone metabolism iv) chronic kidney disease (stage \>3b) and/or liver failure v) neoplastic disease vi) hypersensitivity to alendronate or to any of the excipients vii) abnormalities of the esophagus and other factors which delay esophageal emptying such as stricture or achalasia viii) inability to stand or sit upright for at least 30 minutes ix) hypocalcaemia x) confirmed esophagitis
