Summary

It is hypothesized that effervescent alendronate will be able to maintain bone turnover markers within the pre-menopausal reference range and thereby reducing the likelihood of bone turnover associated changes (rebound effect), after discontinuation of denosumab treatment in a non-osteoporotic population.

Description

Denosumab discontinuation is associated with a rebound effect in bone turnover and loss in bone mass density. These changes resulted in an increase of fracture incidence in patients with postmenopausal osteoporosis back to background levels. However, no excess in fracture incidence was observed. Amongst patients who presented with vertebral fractures after treatment discontinuation, there was a slightly higher incidence of multiple vertebral fractures in patients discontinuing Prolia versus those who discontinued the placebo treatment.

A 2 year, randomized, crossover study demonstrated that alendronate intake after discontinuing denosumab treatment, lead to remaining stable bone mass densitometry (BMD) values in postmenopausal women.

In a study within a non-osteoporotic study population, ongoing at our department, increases in bone turnover are to be expected as soon as patients end study participation (i.e. open label treatment with denosumab, Prolia, anti-RANK ligand inhibition).

It is currently recommended that alternative anti-resorptive therapy may be warranted after Prolia discontinuation. One study describes the use of oral alendronate after denosumab therapy to maintain bone mineral density. However, gastro-intestinal upset and tolerability, as well as difficulty in swallowing pills may limit oral alendronate compliance. To attenuate this concern, buffered soluble (effervescent) alendronate 70 mg, developed with the aim to improve the gastrointestinal tolerability through full dissolution of alendronate in buffered palatable solution before ingestion, will be used.

This study wants to provide a follow up and study wether the use of effervescent alendronate after previous denosumab treatment can prevent a rebound effect in bone turnover that is to be expected when denosumab is discontinued. Subjects that completed our erosive hand OA study and therefore discontinued denosumab 60 mg/every 3 months, will receive alendronate. Moreover, the study wants to asses if there is difference between using alendronate for six or twelve months, starting at the earliest three months but no later than four months after the last injection of denosumab.
