A double-blind, multinational, multicenter, randomised, 2-period crossover study to assess the efficacy and safety of advanced closed-loop insulin delivery with Minimed 670G 4.0 system comparing Faster Insulin Aspart to Standard Insulin Aspart therapy over 4 weeks in active children and adolescents with type 1 diabetes.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
30

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time above range 180 mg/dl
Time Frame: 12 weeks for each arm of the crossover
The primary outcomes is a difference in CGM-measured metrics between periods (Minimed 670G 4.0 closed loop with Faster Insulin aspart and Minimed 670G 4.0 closed loop with Standard Insulin aspart) in superiority for proportion of time >180 mg/dL (10.0 mmol/L)
12 weeks for each arm of the crossover

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Time in range 70-180 mg/dl
Time Frame: 4 weeks for each arm of the crossover
CGM derived indices over the study period of each treatment period ((Minimed 670G 4.0 closed loop with Faster Insulin aspart and Minimed 670G 4.0 closed loop with Standard Insulin aspart)) for 24/7 in time in range 70 to 180 mg/dL (3.9 to 10.0 mmol/L
4 weeks for each arm of the crossover
Time below range <70 mg/dl
Time Frame: 4 weeks for each arm of the crossover
CGM derived indices over the study period of each treatment period ((Minimed 670G 4.0 closed loop with Faster Insulin aspart and Minimed 670G 4.0 closed loop with Standard Insulin aspart)) for 24/7 in time below range 70 mg/dl
4 weeks for each arm of the crossover
Mean glucose
Time Frame: 4 weeks for each arm of the crossover
CGM derived indices over the study period of each treatment period ((Minimed 670G 4.0 closed loop with Faster Insulin aspart and Minimed 670G 4.0 closed loop with Standard Insulin aspart)) for 24/7 in mean glucose

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
