The aim of this study is to characterize the risk of serious cardiovascular (CV) events of myocardial infarction (MI), stroke, and arrhythmia and all-cause mortality including CV death associated with the use of romosozumab, in comparison with other available osteoporosis medications in routine clinical practice in the UK as part of a study using 7 databases from Europe. This will be achieved by meeting three objectives: 1) assessing the incidence of cardiovascular outcomes in romosozumab patients; 2) assessing the incidence of cardiovascular outcomes in patients using other osteoporosis medications and 3) assess the comparative risk of cardiovascular outcomes between patients using romosozumab and alendronate.
The population for this study is women aged 50+ with severe osteoporosis who are prescribed one of the below osteoporotic medications. Severe osteoporosis is identified by the presence of 1 or more fractures of any skeletal sites except face/skull/digit/s fractures recorded in the year prior to therapy initiation.
The exposure of interest is romosozumab. Comparator exposures are alendronate (primary comparator); ibandronate (oral and intravenous); risedronate; zoledronate; denosumab; and teriparatide.
The primary outcome of interest is MACE-2 (first occurrence of death [all cause including cardiovascular (CV) death], MI, or stroke) whilst secondary outcomes are MI; stroke ; death due to CV causes, i.e., MI or stroke; all-cause mortality; MACE-1 (First occurrence of death (CV causes), MI, or stroke), cardiac arrhythmias and atrial fibrillation.
This will be designed using a cohort study with incidence rates of each outcome for each osteoporosis medication calculated using a Poisson model. Meanwhile, cox proportional hazards with propensity score matching will be used for the comparative risk assessment. Multiple sensitivity analyses including negative controls, self-controlled case series (SCCS), and instrumental variable analysis will assess the results for confounding.
Primary: MACE-2 (first occurrence of death [all cause including cardiovascular (CV) death], myocardial infarction (MI), or stroke)
Secondary: MI; Stroke; Death due to CV causes, i.e., MI or stroke; All-cause mortality; MACE-1 (First occurrence of death (CV causes), MI, or stroke), cardiac arrhythmias and atrial fibrillation.
