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.

Detailed Description

To assess a 15-day wear period for the Cascade CGM. The study wear period includes four in-clinic days in which frequent blood draws and Yellow Springs Instrument (YSI) glucose measurements will be performed. Participants will be blinded to CGM glucose values during the study. A retrospective performance assessment will be conducted following the study.

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.

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

18 years and older (ADULT, OLDER_ADULT)

Description

Inclusion Criteria:

  • Diagnosis of type 1 or type 2 (on insulin therapy) diabetes mellitus for at least 6 months
  • 18 years of age or older
  • Currently self-monitoring capillary blood glucose (on average at least three times per day or more) or using a CGM for at least three months -Willing to follow all study procedures, including attending all clinic visits (including in- clinic sessions during which a venous line will be inserted for blood sampling), wearing a CGM sensor(s) for fifteen days, performing fingertip glucose tests for self-monitoring, and keeping a diary of activities.
  • Be willing to wear 2 investigational CGM devices.

Exclusion Criteria:

  1. Known allergy to medical grade adhesives
  2. Magnetic Resonance Imaging (MRI) scheduled during fifteen-day CGM sensor wear period
  3. Persons with type 2 diabetes using diet and exercise only for diabetes management
  4. Used an investigational drug within 30 days prior to study entry
  5. Hematocrit < 35% for females and <40% for males (obtained during screening)
  6. Inadequate veins (in the opinion of the investigator) or known contraindication to placement of a dedicated peripheral line for venous blood withdrawal
  7. Symptomatic coronary artery disease with a history of angina, or history of a myocardial infarction or coronary intervention (e.g., percutaneous transluminal coronary angioplasty (PTCA), stent placement), or coronary artery bypass graft (CABG) within the past six months
  8. Diagnosis of the following diabetic autonomic neuropathies: orthostatic hypotension, heart rate anomalies, gastroparesis
  9. Cerebrovascular incident within the past six months
  10. History or presence of eczema, psoriasis, atopic or contact dermatitis
  11. Subject must not be pregnant at the start of the study.
  12. Current use or within one-week exposure to topical medications at the proposed insertion sites
  13. Seizure disorder (epilepsy)
  14. Malignancy within the past five years, except basal cell or squamous cell skin cancers
  15. Major surgical operation within 30 days prior to screening
  16. Other medical conditions that would pose safety concerns, interfere with study conduct or seriously compromise study integrity (reason for exclusion will be clearly documented by investigator or designee)
  17. Subject has experienced severe hypoglycemia or severe hyperglycemia in the last six months. Severe hypoglycemia is defined as having low blood glucose levels that requires assistance from another person to treat. Severe hypoglycemia is classed as a diabetic emergency. Severe hyperglycemia is defined as a blood ketone level >1.6 millimolar (mM).

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
Feasibility of Use
Time Frame: 15 days
Validate the feasibility of a 15-day wear period of the Cascade CGM. The primary endpoint is an 80% sensor survival rate over a 15-day wear period, which includes four in-clinic days and eleven at-home days.
15 days

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
Performance
Time Frame: 15 days
Accuracy performance compared to YSI readings. The secondary endpoints are: to achieve <15% Mean Average Relative Difference (MARD) and <20mg/dL Mean Average Difference (MAD) compared to YSI readings during the four in-clinic days and to assess Blood Glucose Meter (BGM) fingerstick calibration success.

Primary Completion (ANTICIPATED)

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. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
