Trial Outcomes & Findings for Real-world Effectiveness and Cardiovascular Safety Study of Abaloparatide in Postmenopausal Women (NCT NCT04974723)

NCT ID: NCT04974723

Last Updated: 2024-04-19

Results Overview

A nonvertebral fracture is any fragility fracture at the hip, pelvis, femur, ankle, shoulder (including shoulder, humerus, clavicle), radius/ulna, wrist, or tibia/fibula. The date of the first prescription claim for either abaloparatide or teriparatide during the identification period was considered the index date. A claims-based algorithm with high specificity for fracture site was used to identify osteoporosis related fractures. Patients were followed for up to 18 months after their index date, plus 30 days follow-up or until their first nonvertebral fracture event or hospital death, whichever came first.

Participant Flow

Propensity score (PS) matching was used to create treatment cohorts. Patients were matched using an extensive list of indicators of disease severity and fracture risk, including fracture and treatment history, as well as conditions associated with increased risk of fall and the requirement for treatments associated with poor bone health or quality.

PRIMARY outcome

Timeframe: From index date up to 19 months

Population: All patients meeting the study inclusion/exclusion criteria and selected after PS-matching.

A nonvertebral fracture is any fragility fracture at the hip, pelvis, femur, ankle, shoulder (including shoulder, humerus, clavicle), radius/ulna, wrist, or tibia/fibula. The date of the first prescription claim for either abaloparatide or teriparatide during the identification period was considered the index date. A claims-based algorithm with high specificity for fracture site was used to identify osteoporosis related fractures. Patients were followed for up to 18 months after their index date, plus 30 days follow-up or until their first nonvertebral fracture event or hospital death, whichever came first.

SECONDARY outcome

Timeframe: From index date up to 19 months

Population: All patients meeting the study inclusion/exclusion criteria and selected after PS-matching.

Cardiovascular safety was evaluated based only on events occurring from the beginning of the index period through 19 months. The date of the first prescription claim for either abaloparatide or teriparatide during the identification period was considered the index date. Cardiovascular events (MI and stroke) were defined as the first post-index incidence recorded on a hospital claim or physician claim. A validated claims-based algorithm was used to identify deaths, based on hospital discharge status, that are likely to be caused by cardiovascular events. Patients were followed for up to 18 months while on treatment plus 30 days follow-up, or until their first cardiovascular event (MI or stroke) or hospital death, whichever came first.

The date of the first prescription claim for either abaloparatide or teriparatide during the identification period was considered the index date. A claims-based algorithm with high specificity for fracture site was used to identify osteoporosis related fractures. Patients were followed up for 18 months after their index date, plus 30 days follow-up or until their first hip fracture event or hospital death, whichever came first.
