Clinical Data Collection for the Closed Loop Development for the Type 2 Diabetes Treatment - DT2_1 (DT2_1)

June 10, 2021 updated by: Diabeloop

Development of a Closed Loop for the Treatment of Type 2 Diabetes: Collection of Clinical Data at Home for the Creation of an Algorithmic Laboratory Test Bench

The objective of this study is to collect the evolution of blood glucose levels in type 2 diabetes (T2D) patients under different conditions of their daily life: physical activity, meals, sleep, etc. This data will be used to develop a test bench to evaluate insulin delivery algorithms to treat patients with insulin-resistant T2D using a closed loop.

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.

Detailed Description

T2D is a condition that combines insulin resistance and relative insulin deficiency. The T2D naturally progresses towards an increasingly pronounced insulin deficiency that leads to the need for pancreatic replacement, by administering insulin.

Type 1 diabetes (T1D) requires a complete and immediate substitution of pancreatic insulin secretion. Currently, patients need to be involved in managing their disease by deciding how much insulin to administer based on the results of glucose monitoring. Artificial intelligence, thanks to a self-learning algorithm, enables the automation and customization of insulin administration. These devices, known as closed loops, bring real benefit to the patients included in the studies, by improving glycemic balance, by decreasing the number of hypo- and hyperglycemia but also by decreasing the mental load associated with the disease, improving their quality of life.

These very significant benefits in the T1D treatment open the possibility of obtaining similar benefits in the T2D treated by the basal-bolus type insulin regimen. This study aims to develop a specific algorithm of T2D to meet its particular characteristics.

The objective of this study is to collect the evolution of blood glucose levels in T2D patients under different conditions of their daily life: physical activity, meals, sleep, etc. This data will be used to develop a test bench to evaluate insulin delivery algorithms to treat patients with insulin-resistant T2D using a closed loop.

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.

Ages Eligible for Study

36 years to 71 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

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.

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.

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.
