Issue

On May 21, 2024, the Centers for Medicare & Medicaid Services (CMS) will convene a panel of the Medicare Evidence Development and Coverage Advisory Committee (MEDCAC). The MEDCAC panel will examine what clinical endpoints should be of interest to CMS in studies of new devices for self-management of type 1 and insulin-dependent type 2 diabetes in older adults. The goal of the meeting will be to provide recommendations to CMS regarding a guidance document on this topic, to be issued under the Clinical Endpoints Guidance program.

This need has arisen because the available devices for monitoring and controlling glucose levels have been studied and used primarily in individuals with type 1 diabetes, who historically have not been Medicare-age adults. Although type 2 diabetes is much more common than type 1 diabetes among older adults, better management of type I diabetes is leading to more prolonged survival among patients with type 1 diabetes and, thus, greater numbers of these individuals among the Medicare population. Furthermore, the prevalence of insulin-dependent type 2 diabetes, especially among older adults, is rising. Relevant clinical endpoints for assessing the effectiveness and safety of diabetes management devices may be unique for older adults. For example, the issue of hypotension as a complication of glucose control is a more significant issue among older compared with younger adults.

Studies of devices submitted through the Food & Drug Administration’s Breakthrough Technology pathway have often focused on shorter term data with greater reliance upon intermediate and surrogate outcomes. Although these endpoints may help in answering FDA questions on safety and efficacy, they are generally less helpful for CMS whose focus is on the more ultimate health outcomes associated with the technologies, and particularly for older adults. As a result, there are more frequent evidence gaps in the research literature with respect to the clinically meaningful health outcomes for CMS beneficiaries in assessments of these kinds of medical interventions.

For these reasons, CMS commissioned a Clinical Endpoints Review (CER) of the literature to identify endpoints that should be considered when designing studies of devices for self-management of type 1 or insulin-dependent type 2 diabetes. An endocrinologist with expertise in managing patients with diabetes contributed to the CER. The CER revealed little consensus on outcomes specific to older adults and found few definitions of minimally clinically important differences (MCIDs).

The MEDCAC panel members will make use of the CER as well as their own professional expertise in considering recommendations for CMS. A subcommittee of the full MEDCAC panel reviewed the CER along with responses to the CER from a second external endocrinologist. The subcommittee then assisted CMS in formulating voting questions and a discussion guide for the full panel meeting. By voting on specific questions, and through discussion, MEDCAC panel members will advise CMS on these issues: 1) clinical endpoints considered important for older adults and suggested instruments for measuring those endpoints, 2) MCIDs, and 3) the duration of patient follow-up necessary to demonstrate effectiveness and safety, device durability, and patient adherence.

    DIABETES SELF-MANAGEMENT DEVICES MEDCAC MEETING (May 21, 2024)
    A Preview of the Voting Questions and Discussion Guide

    Following presentations of background information and a time for public comments, the Panel will be asked to provide feedback that CMS will use to draft a Clinical Endpoints Guidance document on this topic. To that end, the remainder of the Panel meeting will be structured as follows:

  • An electronic poll to determine how Panelists rate the importance of 4 endpoint domains under which specific measures can be organized

  • Discussion of each endpoint domain with respect to
    • A prepared list of specific measures
    • Appropriate duration of follow-up
    • Guidance regarding minimal clinically important differences (MCIDs)

    Panelists may find it helpful to print this document, or plan to have it open on their laptops for reference during Panel discussions.

    Voting: Endpoint Domain Ratings

    The following endpoint domains have been identified through a literature review (the Clinical Endpoints Review document) and deliberations of a Panel Subcommittee. They represent the types of endpoints that should be addressed in the body of evidence regarding devices for self-management of type 1 or insulin-dependent type 2 diabetes in older adults. In the meeting, panelists will use rating scales, as shown, to indicate the importance they attach to each endpoint domain.

    1. Surrogate markers, i.e., indirect assessments using biomarkers, physiologic measures, or imaging intended to predict or act as a proxy for a target outcome of interest. For example, percentage of time in hypoglycemia.

      1.   Not at all important
      2.   Slightly important
      3.   Somewhat important
      4.   Very important
      5.   Extremely important

    2. Health outcomes, i.e., direct assessments of a target outcome of interest. For example, complications of diabetes.
      1. Not at all important
      2. Slightly important
      3.   Somewhat important
      4.   Very important
      5.   Extremely important

    3. Quality of life, i.e., patient-reported assessments of symptom burden or function. For example, the Diabetes Distress Scale.
      1.   Not at all important
      2. Slightly important
      3. Somewhat important
      4. Very important
      5. Extremely important

    4. Device-related safety. For example, hypoglycemia-related emergency department visits.
      1. Not at all important
      2.   Slightly important
      3.   Somewhat important
      4.   Very important
      5.   Extremely important

    Discussion

    Please be prepared to discuss the following issues as they apply to each endpoint domain.

    1. The appropriateness of specific endpoint measures within each domain (listed in the Appendix, p. 3 of this document).
    2. Ideal duration of follow-up required for detection of an impact on various endpoint measures.
    3. Any conventional or validated thresholds known to Panel members for defining a Minimally-Clinically Important Difference (MCID) for the endpoints listed in the Appendix.
    Appendix: Specific Outcome Measures by Endpoint Domain

    Surrogate markers

  • Number of hypoglycemic episodes (<70 mg/dL), especially episodes of Level 2 hypoglycemia (<54 mg/dL) 
  • Percentage of time in level 2 hypoglycemia (<54 mg/dL) 
  • Impact on A1C (MCID = 0.5% change)*
  • Percentage of time in acceptable glucose range (70-180 mg/dL)
  • Percentage of time in hyperglycemia (>180 mg/dL)
  • Percentage of time in hypoglycemia (<70 mg/dL) 

    • *According to Endocrine Society practice guidelines, A1C should be used for glucose monitoring only on the basis of shared-decision making when patients are not in good health, i.e., they have ≥ 3 nondiabetes chronic illnesses, mild cognitive impairment, dementia (any stage), ≥ 2 ADL impairments, end-stage medical condition, or residence in a long-term nursing facility. The American Diabetes Association also cautions against using A1C to monitor patients in very poor health.

    Health outcomes

  • Restoration of hypoglycemia awareness
  • Cognitive function changes
  • Diabetes-related emergency department visits
  • Diabetes-related hospitalizations
  • Complications of diabetes, e.g., kidney disease, major adverse cardiovascular events (MACE)

    • Quality of life

  • Audit of Diabetes-Dependent Quality of Life (ADDQoL) questionnaire
  • Diabetes Distress Scale
  • Diabetes Impact Measurement Scales (DIMS)
  • Diabetes Treatment Satisfaction Questionnaire
  • Hypoglycemia Fear Survey
  • Problem Areas in Diabetes

    • Device-related safety

  • Hypoglycemia-related emergency department visits
  • Harms such as tissue damage, if appropriate
  • Device discontinuation rates
  • Patient preferences (comparing the device with conventional self-management) and adherence
