Bazedoxifene Post Approval Safety Study (PASS) in the European Union (EU)

Completed
Conditions
Osteoporosis, Postmenopausal
Interventions
Registration Number
NCT01416194
Lead Sponsor
Pfizer
Brief Summary

This observational cohort study is being conducted to further characterize selected adverse events of interest among a patient population with osteoporosis who are prescribed bazedoxifene, raloxifene, or a bisphosphonate in usual clinical care outside of a randomized clinical trial setting. The study will compare the rates of the selected clinical events among the three treatment groups.

Detailed Description

All women in the database meeting the inclusion criteria will be included in the study without any statistical sampling.

Primary Outcome Measures
NameTimeMethod
Cumulative Incidence of Venous Thromboembolism (VTE)Up to a maximum of follow-up period of 92.1 months

VTE is defined as deep vein thrombosis (DVT), pulmonary embolism (PE), retinal vein thrombosis, and sinus thrombosis. DVT: occurs when a blood clot forms in a vein located deep inside the body. PE: a blockage of an artery in the lungs by a substance that has moved from elsewhere in the body through the bloodstream (embolism). Sinus thrombosis: presence of a blood clot in the dural venous sinuses, which drain blood from the brain. Retinal vein thrombosis: blockage of the small veins that carry blood away from the retina. Cumulative incidence was calculated as total participants with VTE events during follow-up period divided by total persons at risk during follow-up period\*100 and hence cumulative incidence was expressed as percentage of participants.

Secondary Outcome Measures
NameTimeMethod
Cumulative Incidence of Cardiac DisordersUp to a maximum of follow-up period of 92.1 months

Cardiac disorders included myocardial infarction, myocardial ischemia, and coronary occlusion. Cumulative incidence was calculated as total participants with cardiac disorders events during follow-up period divided by total persons at risk during follow-up period\*100 and hence cumulative incidence was expressed as percentage of participants.

Cumulative Incidence of Atrial FibrillationUp to a maximum of follow-up period of 92.1 months

Atrial fibrillation is an irregular heartbeat that increases the risk of stroke and heart disease. Cumulative incidence was calculated as total participants with atrial fibrillation events during follow-up period divided by total persons at risk during follow-up period\*100 and hence cumulative incidence was expressed as percentage of participants.

Cumulative Incidence of HypertriglyceridemiaUp to a maximum of follow-up period of 92.1 months

Hypertriglyceridemia refers to high blood levels of triglycerides. Cumulative incidence was calculated as total participants with hypertriglyceridemia events during follow-up period divided by total persons at risk during follow-up period\*100 and hence cumulative incidence was expressed as percentage of participants.

Cumulative Incidence of Renal FailureUp to a maximum of follow-up period of 92.1 months

Cumulative incidence was calculated as total participants with renal failure events during follow-up period divided by total persons at risk during follow-up period\*100 and hence cumulative incidence was expressed as percentage of participants.

Cumulative Incidence of Ischemic StrokeUp to a maximum of follow-up period of 92.1 months

Ischemic stroke is caused by a blockage in an artery that supplies blood to the brain. Cumulative incidence was calculated as total participants with ischemic stroke events during follow-up period divided by total persons at risk during follow-up period\*100 and hence cumulative incidence was expressed as percentage of participants.

Cumulative Incidence of DepressionUp to a maximum of follow-up period of 92.1 months

Cumulative incidence was calculated as total participants with depression events during follow-up period divided by total persons at risk during follow-up period\*100 and hence cumulative incidence was expressed as percentage of participants.

Cumulative Incidence of Thyroid Disorders- GoitreUp to a maximum of follow-up period of 92.1 months

Goitre is a swelling in the neck resulting from an enlarged thyroid gland. Cumulative incidence was calculated as total participants with thyroid disorders-goitre events during follow-up period divided by total persons at risk during follow-up period\*100 and hence cumulative incidence was expressed as percentage of participants.

Cumulative Incidence of Biliary EventsUp to a maximum of follow-up period of 92.1 months

Biliary events included cholecystitis and cholelithiasis. Cumulative incidence was calculated as total participants with biliary events during follow-up period divided by total persons at risk during follow-up period\*100 and hence cumulative incidence was expressed as percentage of participants.

Cumulative Incidence of Clinical FracturesUp to a maximum of follow-up period of 92.1 months

A fracture is a break in a bone. Cumulative incidence was calculated as total participants with clinical fractures events during follow-up period divided by total persons at risk during follow-up period\*100 and hence cumulative incidence was expressed as percentage of participants.

Cumulative Incidence of All MalignanciesUp to a maximum of follow-up period of 92.1 months

All malignancies included and not limited only to thyroid, breast, renal, genital / urogenital, lung cancer, gastrointestinal tract and respiratory tract. Cumulative incidence was calculated as total participants with malignancies events during follow-up period divided by total persons at risk during follow-up period\*100 and hence cumulative incidence was expressed as percentage of participants.

Cumulative Incidence of Selected Ocular EventsUp to a maximum of follow-up period of 92.1 months

Selected ocular events included retinal vascular occlusions, disorders of the globe, iris, ciliary body, retina, eye adnexa and cornea. Cumulative incidence was calculated as total participants with selected ocular events during follow-up period divided by total persons at risk during follow-up period\*100 and hence cumulative incidence was expressed as percentage of participants.

Cumulative Incidence of Different Types of MalignanciesUp to a maximum of follow-up period of 92.1 months

In this outcome measure, cumulative incidence of different types of malignancies included breast, renal, thyroid, genital / urogenital, gastrointestinal tract, lung and respiratory tract were calculated. Cumulative incidence for each type of malignancy was calculated as total participant with the respective malignancy events during follow-up period divided by total persons at risk during follow-up period\*100 and hence cumulative incidence for each type of malignancy was expressed as percentage of participants.
