Evenity is the same class of drug as Prolia a monoclonal antibody . These two drugs work in opposite ways. Evenity works to build bone, while Prolia supresses bone loss. Prolia suppresses the cells that break bone down. The scary side of Prolia is that when you stop the drug all the precurser bone-breaking cells that have been collecting mature. Rebound vengence on your bones can be quickly devastating.
You don't mention why you want to quit Prolia. Some endocrinologists would advise that you stay on it. My own impulse would be to switch. The excerpt below would have me choosing Evenity.
"The effect of transitioning to [Evenity] romosozumab after [Prolia] denosumab was evaluated in a phase two study of
romosozumab [35]. When administered after denosumab in postmenopausal women with low BMD, romosozumab increased BMD in the lumbar spine by 2.3% and maintained BMD in the hip, although the increase was of a smaller magnitude than that observed in treatment-naïve patients [35]. While the results of this study suggest that romosozumab may offset the rebound increase in bone resorption observed after denosumab discontinuation, more data are needed to determine whether patients will benefit from transitioning from denosumab to romosozumab. https://www.e-enm.org/journal/view.php?doi=10.3803/EnM.2021.1369
I have a bias against drugs the suppress remodeling which is the action of Prolia and the bisphosphonates. So this would be an easy decision for me.
After Evenity another round of Forteo?
Best luck with your decision.
