cross-section of clinical practice settings

Inclusion criteria

  • The following inclusion criteria are consistent with information in the SYMLIN package insert and apply to insulin using patients with type 2 or type 1 diabetes who:

    • Have failed to achieve the desired or optimal level of glycemic control despite utilizing appropriate, individualized insulin regimens
    • Have A1C \<=9.0% within 3 months of study enrollment
    • Are receiving ongoing diabetes care under the guidance of a Health Care Provider (HCP) trained in the use of SYMLIN

Exclusion criteria

Exclusion Criteria:

  • The following exclusion criteria are consistent with the SYMLIN package insert and specifically exclude patients who:

    • Are poorly compliant with their current insulin regimen, as defined by their HCP
    • Are poorly compliant with prescribed blood glucose self monitoring, as defined by their HCP
    • Have experienced recurrent patient-ascertained severe hypoglycemia requiring assistance during the past 6 months
    • Have hypoglycemia unawareness
    • Have a confirmed diagnosis of gastroparesis
    • Require the use of drugs that stimulate gastrointestinal motility
    • Are female and pregnant or lactating and for whom the HCP determines the potential benefit does not justify the potential risk to the fetus or infant
    • Have been treated with SYMLIN within 3 months prior to study start

What researchers measure

Primary outcomes

  1. Incidence of Patient-Ascertained Severe Hypoglycemia (PASH) During the Adjustment Period

    PASH is defined as episodes of hypoglycemia requiring the assistance of another individual (including aid in ingestion of oral carbohydrate); and/or requiring the administration of glucagon injection, intravenous glucose, or other medical intervention. The adjustment period represents the initial 0-3 months of pramlintide treatment

    Time frame: 0-3 months

  2. Annual Event Rate of Patient-Ascertained Severe Hypoglycemia (PASH) During the Adjustment Period

    The annual event rate was calculated as the total number of events during the time period divided by the total years of exposure to pramlintide for all patients during the time period. The adjustment period represents the initial 0-3 months of pramlintide treatment. PASH is defined as episodes of hypoglycemia requiring the assistance of another individual (including aid in ingestion of oral carbohydrate); and/or requiring the administration of glucagon injection, intravenous glucose, or other medical intervention.

    Time frame: 0-3 months

Secondary outcomes

  1. The Incidence of Patient-Ascertained Severe Hypoglycemia (PASH) During the Steady State Period

    The steady state period represents the \>3-6 months of pramlintide treatment following the adjustment period. PASH is defined as episodes of hypoglycemia requiring the assistance of another individual (including aid in ingestion of oral carbohydrate); and/or requiring the administration of glucagon injection, intravenous glucose, or other medical intervention.

    Time frame: >3-6 months

  2. The Annual Event Rate of Patient-Ascertained Severe Hypoglycemia (PASH) During the Steady State Period

    The annual event rate was calculated as the total number of events during the time period divided by the total years of exposure to pramlintide for all patients during the time period. The steady state period represents the \>3-6 months of pramlintide treatment following the adjustment period. PASH is defined as episodes of hypoglycemia requiring the assistance of another individual (including aid in ingestion of oral carbohydrate); and/or requiring the administration of glucagon injection, intravenous glucose, or other medical intervention.

    Time frame: >3-6 months

  3. Incidence of Medically Assisted Severe Hypoglycemia (MASH) During the Adjustment Period

    MASH is defined as episodes of severe hypoglycemia requiring IM glucagon, IV glucose, hospitalization, paramedic assistance, emergency room visit, and/or is assessed as a serious adverse event (SAE) by the investigator. MASH is a subset of PASH. The adjustment period represents the initial 0-3 months of pramlintide treatment

    Time frame: 0-3 months

  4. The Annual Event Rate of Medically Assisted Severe Hypoglycemia (MASH) During the Adjustment Period

The adjustment period represents the initial 0-3 months of pramlintide treatment. MASH is defined as episodes of severe hypoglycemia requiring IM glucagon, IV glucose, hospitalization, paramedic assistance, emergency room visit, and/or is assessed as a serious adverse event (SAE) by the investigator. MASH is a subset of PASH.

    Time frame: 0-3 months

  5. Incidence of Medically Assisted Severe Hypoglycemia (MASH) During the Steady State Period

    The steady state period represents the \>3-6 months of pramlintide treatment following the adjustment period. MASH is defined as episodes of severe hypoglycemia requiring IM glucagon, IV glucose, hospitalization, paramedic assistance, emergency room visit, and/or is assessed as a serious adverse event (SAE) by the investigator. MASH is a subset of PASH.

    Time frame: >3-6 months

  6. Annual Event Rate of Medically Assisted Severe Hypoglycemia (MASH) During the Steady State Period

    The annual event rate was calculated as the total number of events during the time period divided by the total years of exposure to pramlintide for all patients during the time period. The steady state period represents the \>3-6 months of pramlintide treatment following the adjustment period. MASH is defined as episodes of severe hypoglycemia requiring IM glucagon, IV glucose, hospitalization, paramedic assistance, emergency room visit, and/or is assessed as a serious adverse event (SAE) by the investigator. MASH is a subset of PASH.
