What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of Below-knee Lower Extremity Amputation in Type 2 Diabetes Mellitus (T2DM) Patients Newly Exposed to Sodium-glucose Co-transporter 2 Inhibitors (SGLT2i) Overall and in the Subgroup With High Cardiovascular (CV) Risk
The occurrence of a below-knee lower extremity amputation will be defined by observing an associated procedure code in the outpatient or inpatient medical service claims.
Measured: up to 6 years (estimated study duration)
Incidence of Below-Knee Lower Extremity Amputation in T2DM Patients Newly Exposed To non-SGLT2i Aha Overall And In The Subgroup With High CV Risk
The occurrence of a below-knee lower extremity amputation will be defined by observing an associated procedure code in the outpatient or inpatient medical service claims.
Measured: up to 6 years (estimated study duration)
Incidence of Below-Knee Lower Extremity Amputation in Canagliflozin New Users Versus non-SGLT2i Aha New Users
Hazard ratio will be estimated using a conditional Cox proportional hazards model based on propensity-matched cohorts.
Measured: up to 6 years (estimated study duration)

Questions about this trial
What is this clinical trial studying?
An observational study of Diabetes Mellitus, Type 2, run by Janssen Research & Development, LLC.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 30 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of Below-knee Lower Extremity Amputation in Type 2 Diabetes Mellitus (T2DM) Patients Newly Exposed to Sodium-glucose Co-transporter 2 Inhibitors (SGLT2i) Overall and in the Subgroup With High Cardiovascular (CV) Risk (time frame: up to 6 years (estimated study duration)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Aug 2017.
