Assessing Non-adjunctive CGM Safety at Home and in New Markets (ANSHIN)

July 28, 2022 updated by: DexCom, Inc.
The purpose of the study is to examine whether non-adjunctive (without having to double check using another method) use of Continuous Glucose Monitoring improves A1c in adults or children with diabetes managed by intensive insulin therapy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

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.
85

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

2 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

Genders Eligible for Study

Description

Inclusion Criteria

  • Age 2 years or older
  • A diagnosis of T1D or T2D made at least 6 months prior to enrollment. At least 20 adult participants will have T1D; and 10 will have T2D; 10 participants will be over age 65 years.
  • Using IIT (either an insulin pump or MDI)
  • HbA1c value ≥ 7.5% (≥ 58 mmol/mol) measured by local lab within prior 30-days before enrollment or by point of care at time of screening.
  • eGFR ≥ 30 within the last 90-days prior to enrollment (adult participants only)
  • Currently performing 2 or more SMBG fingersticks a day by historical average and willing to continue this during the blinded CGM wear.

Exclusion Criteria

  • Use of real-time or intermittently scanned CGM in the 6 months prior to enrollment.
  • BMI > 45.
  • Anticipated changes to insulin delivery method or insulin formulation(s).
  • Insulin formulation changes within class will be permitted if required per formulary change and represent equivalent therapy (eg: insulin lispro change to insulin aspart).
  • Pregnancy (as demonstrated by a positive test at study entry) at time of screening or are planning to become pregnant during the study.
  • Applicable only to women of reproductive potential.
  • Planned or currently using weight reduction medications, programs or surgery. Defined as 1) using weight loss medications and losing weight (e.g. chronic use of weight loss medications with stable weight is not exclusionary) or planning on using weight loss prescription medication during the study; 2) currently using or planning on initiating a modified fasting program (e.g. protein-sparing diet plans) during the study; or 3) bariatric surgical procedure within the past year or plans for undergoing bariatric surgery during the study.
  • Concomitant disease or condition that may compromise patient safety including, but not limited to; severe mental illness, a diagnosed or suspected eating disorder or any uncontrolled long-term medical/psychiatric condition that would interfere with study- related tasks or visits, including ongoing treatment for a significant malignancy. These assessments/conditions are made at investigator's discretion.
  • Known (or suspected) significant allergy to medical-grade adhesives.
  • Any condition, per investigator assessment, that could impact the stability of the HbA1c measurement, for example,
  • Acute or chronic blood loss or bleeding disorder,
  • Red blood cell transfusion or erythropoietin, administration in the 3 months prior to enrollment,
  • Or red blood cell transfusion or erythropoietin administration anticipated during the course of the study.
  • Anticipated acute use of oral or injectable glucocorticoids that could affect glycemic control and impact HbA1c, for example,
  • Frequent steroid bursts used for inflammatory arthritis or inflammatory bowel disease,
  • Or recurrent lumbar epidural steroid injections,
  • Current treatment with hydroxyurea
  • Participation in another pharmaceutical or device trial at the time of enrollment or during the study.
