About this study
Official title: ASPIRE (Automation to Simulate Pancreatic Insulin Response): Pivotal In Home Study to Determine Safety and Efficacy of the LGS Feature in Sensor-augmented Pumps
Introduction:
The purpose of the pivotal In Home study is to collect clinical data on the safety and efficacy of the Paradigm LGS System in the actual use environment and by the intended use population. ASPIRE is a multi-center, in home, randomized parallel adaptive study design with type 1 diabetes. The study will compare A1C and CGM based nocturnal hypoglycemic events in a treatment arm to a control arm. Arms are defined as:
Read more
- Treatment Arm (LGS ON) using Paradigm® VEO™ Pump
- Control Arm (NO LGS FEATURE ) using Paradigm® Revel™2.0 Pump
The study's objectives are two-fold:
- The first study objective is to demonstrate that home use of Low Glucose Suspend (LGS) is safe and is not associated with glycemic deterioration, as measured by change in A1C from baseline to end of study participation.
- The second study objective is to demonstrate that home use of Low Glucose Suspend (LGS) is associated with reduction in nocturnal hypoglycemia when patients fail to respond.
Primary Safety Endpoint:
The change in A1C from randomization to the end of the treatment period will be used to demonstrate that the automatic insulin delivery suspension (LGS ON) does not result in an unacceptable worsening of glycemic control.
- Conditions
- Type 1 Diabetes
- Being tested
- Medtronic MMT-754 Veo Insulin pump testing Low Glucose Suspend (LGS) feature, Medtronic (NO LGS FEATURE ) using Paradigm® Revel™2.0 Pump

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in A1C From Baseline to End of Study Participation
The first study objective is to demonstrate that home use of Low Glucose Suspend (LGS) is safe and is not associated with glycemic deterioration, as measured by change in A1C from baseline to end of study participation.
Measured: 5 months
The Event Area Under the Curve (AUC) Was Used to Demonstrate the Reduction of Nocturnal Hypoglycemia With the Low Glucose Suspend (LGS) Feature (LGS ON)
An event is identified as: LGS feature in the correct setting; CGM values <= 65 mg/dL continuously with starting time between 10pm - 8am; No evidence of patient intervention during the first 20 minutes when CGM value was <= 65 mg/dL; The rate of change before reaching sensor glucose value of <= 65 mg/dL was <= 5 mg/dl/minutes; If the time between two successive events was less than 30 minutes, they will be combined as one event; An evaluable event is defined as any event with CGM value <= 65 mg/dL of greater than 20 minutes and the LGS feature is on the correct setting; Event AUC analysis was performed based on logarithm of AUC data.
Measured: 5 months

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Medtronic MMT-754 Veo Insulin pump testing Low Glucose Suspend (LGS) feature and Medtronic (NO LGS FEATURE ) using Paradigm® Revel™2.0 Pump in people with Type 1 Diabetes, run by Medtronic MiniMed, Inc. at 17 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 18 inclusion and 27 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 17 Mar 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 17 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.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 17 Mar 2014). 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?
Change in A1C From Baseline to End of Study Participation (time frame: 5 months). 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 NCT01497938, which also lists 4 linked publications.
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 17 Mar 2014.
