About this study

Official title: A Performance Evaluation of the Enlite™ and Enlite 3 Glucose Sensor to Support Use in Children

The purpose of this study is to evaluate the Enlite Sensor™ and Enlite 3 Sensor performance in pediatric patients with insulin requiring diabetes at the beginning, middle and end of sensor wear.

Read the detailed description

This study is a prospective, single arm, multi-center, in-clinic study.. There will be two consecutive phases of the study:

A total of up to 260 subjects (2-18 years old) will be enrolled at up to 15 investigational centers

Subjects will come for clinic visit for YSI reference glucose testing and for Enlite Sensor™ and Enlite 3 Sensor™ testing. SMBG (Self-Monitoring of Blood Glucose) reference measurement is for subjects 2-6 years of age and cannot tolerate YSI.

Study has a run-in period and a study period with a total of 10 visits

Conditions: Insulin Requiring Diabetes
Being tested: Enlite sensors
Keywords: Insulin requiring diabetes, Children, Sensor, Accuracy

Study groups in NCT01991470
Study group	Role	What they receive
Enlite sensors	Experimental	Each subject will first wear enlite sensors and will come for clinic visit for YSI (Yellow Spring Instruments). Then each subject will wear enlite 3 sensors and will come for clinic visit for YSI (Yellow Spring Instruments) or SMBG (Self-Monitoring of Blood Glucose) testing. SMBG testings are for subjects 2-6 years of age and cannot tolerate YSI. In addition. In addition, subjects aged 2-6 years old will not participate in Enlite phase. They only participate in Enlite 3 phase. Receives: Device: Enlite sensors

What is being measured

The primary outcome is the main question the study is designed to answer.

Enlite Sensor Accuracy Mean Absolute Relative Difference (MARD), With Lower Serial Number 530G Pump
Enlite Sensor accuracy relative to the YSI (Yellow Spring Instruments) reference. Each subject wore two 530G pumps. The results for the lower serial number pump worn by each subject were arbitrarily selected and pooled across subjects for the primary dataset. MARD = Mean of ((Absolute difference of YSI reference and Sensor glucose values / YSI reference glucose values) * 100). Therefore, the unit of MARD is percentage (%). Note that results from multiple testing days were pooled together for reporting purpose.
Measured: 6 days
Enlite 3 Sensor Accuracy Mean Absolute Relative Difference (MARD), With the Guardian Mobile System
Enlite 3 Sensor accuracy using Guardian Mobile System compared to YSI or SMBG (Self-Monitoring of Blood Glucose) reference values. For subjects 2-6 years of age, SMBG was used as a reference value if YSI cannot be tolerated. MARD = Mean of ((Absolute difference of reference and Sensor glucose values / reference glucose values) * 100). Therefore, the unit of MARD is percentage (%). Note that results from multiple testing days will be pooled together for reporting purpose.
Measured: 7 days

Secondary outcomes (6)

Enlite 3 Sensor Accuracy Mean Absolute Relative Difference (MARD), With the GST3C Transmitter
Enlite 3 Sensor accuracy using GST3C transmitter used as a recorder compared to YSI or SMBG reference values. For subjects 2-6 years of age, SMBG was used as a reference value if YSI cannot be tolerated. MARD = Mean of ((Absolute difference of reference and Sensor glucose values / reference glucose values) * 100). Therefore, the unit of MARD is percentage (%). Note that results from multiple testing days will be pooled together for reporting purpose.
Measured: 7 days
Enlite Sensor Accuracy Mean Absolute Relative Difference (MARD), With Higher Serial Number 530G Pump
Enlite Sensor accuracy relative to the YSI reference. Each subject wore two 530G pumps. The results for the higher serial number pump worn by each subject were arbitrarily selected and pooled across subjects for the secondary dataset. MARD = Mean of ((Absolute difference of YSI reference and Sensor glucose values / YSI reference glucose values) * 100). Therefore, the unit of MARD is percentage (%). Note that results from multiple testing days were pooled together for reporting purpose.
Measured: 6 Days
Enlite Sensor Accuracy Mean Absolute Relative Difference (MARD), With Lower Serial Number 530G Pump, Using One Additional Calibration During FST
Enlite Sensor accuracy relative to the YSI reference, using one additional calibration during FST. MARD = Mean of ((Absolute difference of YSI reference and Sensor glucose values / YSI reference glucose values) * 100). Therefore, the unit of MARD is percentage (%). Note that results from multiple testing days were pooled together for reporting purpose.
Measured: 6 Days
Enlite Sensor Accuracy Mean Absolute Relative Difference (MARD), With Higher Serial Number 530G Pump, Using One Additional Calibration During FST
Enlite Sensor accuracy relative to the YSI reference, using one additional calibration during FST. MARD = Mean of ((Absolute difference of YSI reference and Sensor glucose values / YSI reference glucose values) * 100). Therefore, the unit of MARD is percentage (%). Note that results from multiple testing days were pooled together for reporting purpose.
Measured: 6 Days
Enlite 3 Sensor Accuracy Mean Absolute Relative Difference (MARD), With the Guardian Mobile System, Using One Additional Calibration During FST
Enlite 3 Sensor accuracy using Guardian Mobile System compared to YSI or SMBG reference values, with one additional calibration during FST. For subjects 2-6 years of age, SMBG was used as a reference value if YSI cannot be tolerated. MARD = Mean of ((Absolute difference of reference and Sensor glucose values / reference glucose values) * 100). Therefore, the unit of MARD is percentage (%). Note that results from multiple testing days will be pooled together for reporting purpose.
Measured: 7 Days
Enlite 3 Sensor Accuracy Mean Absolute Relative Difference (MARD), With GST3C Transmitter, Using One Additional Calibration During FST
Enlite 3 Sensor accuracy using GST3C transmitter used as a recorder compared to YSI or SMBG reference values, with one additional calibration during FST. For subjects 2-6 years of age, SMBG was used as a reference value if YSI cannot be tolerated. MARD = Mean of ((Absolute difference of reference and Sensor glucose values / reference glucose values) * 100). Therefore, the unit of MARD is percentage (%).

Questions about this trial

What is this clinical trial studying?

A study testing Enlite sensors in people with Insulin Requiring Diabetes, run by Medtronic MiniMed, Inc. at 11 sites in United States.

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 6 inclusion and 5 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 27 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Yes. Results are posted in the registry (first posted 27 Sep 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Enlite Sensor Accuracy Mean Absolute Relative Difference (MARD), With Lower Serial Number 530G Pump (time frame: 6 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01991470, which also lists 1 linked publication.

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 27 Sep 2018; AzTrials last refreshed its copy on 27 Oct 2026.
