PROMISE Study: An Evaluation of an Implantable Continuous Glucose Sensor up to 180 Days (PROMISE)

July 25, 2024 updated by: Senseonics, Inc.

PROMISE Study: A Prospective, Multicenter Evaluation of Accuracy and Safety of an Implantable Continuous Glucose Sensor Lasting up to 180 Days

The purpose of this clinical investigation is to evaluate the accuracy of the Eversense® continuous Glucose Monitoring System (Eversense® 180 CGM System) measurements when compared with reference standard measurements up to 180 days of sensor use.

The investigation will also evaluate safety of the Eversense® 180 CGM System usage.

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)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Adult subjects, age ≥18 years
  2. Clinically confirmed diagnosis of diabetes mellitus for ≥1 year
  3. Subject has signed an informed consent form and is willing to comply with protocol requirements

Exclusion Criteria:

  1. History of unexplained severe hypoglycemia in the previous 6 months. Severe hypoglycemia is defined as hypoglycemia resulting in loss of consciousness or seizure
  2. History of diabetic ketoacidosis requiring emergency room visit or hospitalization in the previous 6 months
  3. Subjects with gastroparesis
  4. Female subjects of childbearing capacity (defined as not surgically sterile or not menopausal for ≥ 1 year) who are lactating or pregnant, intending to become pregnant, or not practicing birth control during the course of the study.
  5. A condition preventing or complicating the placement,operation, or removal of the Sensor or wearing of transmitter, including upper extremity deformities or skin condition.
  6. Symptomatic coronary artery disease; unstable angina; myocardial infarction, transient ischemic attack or stroke in the past 6 months; uncontrolled hypertension (systolic>160 mm Hg or diastolic >100 mm Hg at time of screening); current congestive heart failure; history of cardiac arrhythmia (benign PACs and PVCs allowed). Subjects with asymptomatic coronary artery disease (e.g. CABG, stent placement or angioplasty) may participate if negative stress test within 1 year prior to screening and written clearance from Cardiologist documented.
  7. Hematocrit <30% or >60%
  8. History of hepatitis B, hepatitis C, or HIV
  9. Current treatment for a seizure disorder unless written clearance by neurologist to participate in study
  10. History of adrenal insufficiency
  11. Currently receiving (or likely to need during the study period): immunosuppressant therapy; chemotherapy; anticoagulant/antithrombotic therapy (excluding aspirin); glucocorticoids (excluding ophthalmic or nasal). This exclusion does include the use of inhaled glucocorticoids and the use of topical glucocorticoids (over sensor site only); antibiotic for chronic infection (e.g. osteomyelitis, endocarditis)
  12. A condition requiring or likely to require magnetic resonance imaging (MRI)
  13. Known topical or local anesthetic allergy
  14. Known allergy to glucocorticoids
  15. Any condition that in the investigator's opinion would make the subject unable to complete the study or would make it not in the subject's best interest to participate in the study. Conditions include but are not limited to psychiatric conditions, known current or recent alcohol abuse or drug abuse by subject history, a condition that may increase the risk of induced hypoglycemia or risk related to repeated blood testing. Investigator will supply rationale for exclusion
  16. Participation in another clinical investigation (drug or device) within 2 weeks prior to screening or intent to participate during the study period
  17. The presence of any other active implanted device (as defined further in protocol)

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
Effectiveness Measure - Mean Absolute Relative Difference (MARD) for Paired CGM and Reference Glucose Measurements
Time Frame: 180 days
The effectiveness endpoint is the mean absolute relative difference (MARD), calculated for paired CGM Sensor and reference glucose measurements through 180 days post-sensor insertion for reference glucose values from 40-400 mg/dL. MARD is defined as the average of absolute difference of paired Sensor and reference glucose readings divided by the reference glucose reading (reference) for reference glucose values from 40-400 mg/dL, that is: MARD = ((SUM | (Glucose)sensor - (Glucose)reference | / (Glucose)reference ) / n ) x 100%, where n is the total number of Sensor and reference glucose pairs after 180 days of sensor use (MARD is expressed as a percent). Lower MARDs indicate higher (better) accuracy.
180 days
Safety Endpoint - Incidence of Device-related or Sensor Insertion/Removal Procedure-related Serious Adverse Events
Time Frame: 180 days
Incidence of device-related or sensor insertion/removal procedure-related serious adverse events occurring up to 180 days after the insertion procedure.
180 days
