NCT02733588

Brief Summary

The primary objective of this study is to test an optimized control system for sensor-guided (physician administered) delivery of glucagon, and test Proof-of-Concept (POC) in a clinical setting in patients with severe hypoglycemia following bariatric surgery.

Outcome Measures

Primary Outcomes (1)

  • Detection/Notification of Hypoglycemia

    Frequency with which the device controller software correctly identifies impending hypoglycemia (glucose \< 75 mg/dl) and notifies the investigator to initiate treatment. Reported as the number of successful identifications.

    0 - 120 minutes following dosing

Secondary Outcomes (3)

  • Number of Subjects With Severe Hypoglycemia

    0 - 120 minutes following dosing

  • Number of Subjects With Rebound Hyperglycemia

    0 - 120 minutes following dosing

  • Glucose Time in Range

    0 - 120 minutes following dosing

Study Arms (1)

G-Pump™ (glucagon infusion)

EXPERIMENTAL

0.15 or 0.3 mg G-Pump™ (glucagon infusion) administered from OmniPod® pump

Drug: G-Pump™ (glucagon infusion)

Interventions

0.15 or 0.3 mg G-Pump™ (glucagon infusion) administered from OmniPod® pump

Also known as: glucagon
G-Pump™ (glucagon infusion)

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • diagnosed with ongoing post-bariatric hypoglycemia with prior episodes of neuroglycopenia, unresponsive to dietary intervention (low glycemic index, controlled carbohydrate portions) and trial of acarbose therapy at the maximally tolerated dose.
  • willingness to provide informed consent and follow all study procedures, including attending all scheduled visits.

You may not qualify if:

  • documented hypoglycemia occurring in the fasting state (\> 12 hours fast);
  • chronic kidney disease stage 4 or 5;
  • hepatic disease, including serum alanine aminotransferase or aspartate aminotransferase greater than or equal to 3 times the upper limit of normal; hepatic synthetic insufficiency as defined as serum albumin \< 3.0 g/dL; or serum bilirubin \> 2.0;
  • congestive heart failure, New York Heart Association class II, III or IV;
  • history of myocardial infarction, unstable angina or revascularization within the past 6 months;
  • history of a cerebrovascular accident;
  • seizure disorder (other than with suspect or documented hypoglycemia);
  • active treatment with any diabetes medications except for acarbose;
  • active malignancy, except basal cell or squamous cell skin cancers;
  • personal or family history of pheochromocytoma or disorder with increased risk of pheochromocytoma (MEN 2, neurofibromatosis, or Von Hippel-Lindau disease);
  • known insulinoma;
  • major surgical operation within 30 days prior to screening;
  • hematocrit ≤ 33%;
  • bleeding disorder, treatment with warfarin, or platelet count \<50,000;
  • blood donation (1 pint of whole blood) within the past 2 months;
  • +5 more criteria

Limitations and Caveats

Sample size was small; gender mix, although unequal, is typical of the PBH population at Joslin. The protocol was modified at every stage to test iterations of the detection algorithm and/or increasing glucagon doses to prevent hypoglycemia.
