简要总结
This is a pilot study designed to determine if the bihormonal bionic pancreas provides improved blood glucose control, compared to the current standard of care, in individuals with hyperinsulinism who developed diabetes after having a pancreatectomy.
详细描述
The management of diabetes following pancreatectomy for hyperinsulinism (HI) generally consists of the same approaches that are used for individuals with type 1 diabetes (T1D). However, there are significant differences in individuals with HI and post-pancreatectomy diabetes that increases the risk of hypoglycemia in these individuals and prevent achieving tight glycemic control. Individuals with HI have glucagon deficiency and unlike T1D, those with HI and post-pancreatectomy diabetes have residual dysregulated insulin secretion that results in marked hypo- and hyper-glycemia. Furthermore, pancreatic insufficiency can result in disturbances in nutrient absorption and fluctuations in glucose concentrations.
Current treatment approaches with intermittent subcutaneous insulin administration or insulin pump therapy offer inadequate glycemic control in these individuals. We propose a novel approach to the management of these individuals with the bihormonal bionic pancreas to replace both hormones, insulin and glucagon, through an automated glycemic management system.

- •On insulin therapy with a regimen of at least 11 units/kg/day.
- •Treatment with subcutaneous insulin by pump at the time of recruitment.
- •Prescription medication regimen stable for > 1 month (except for medications that will not affect the safety of the study and are not expected to affect any outcome of the study, in the judgment of the site PI).
- •Females > 11 years of age must have a negative urine/serum pregnancy test and must use an acceptable method of contraception, including abstinence, a barrier method (diaphragm or condom), Depo-Provera, or an oral contraceptive, for the duration of the study.
- •Informed consent, parental/guardian permission (informed consent) and if appropriate, child assent.
排除标准
- •Unable to provide informed consent (e.g. impaired cognition or judgment).
- •Evidence of a medical condition that might alter results or compromise the interpretation of results, including active infection, kidney failure, severe liver dysfunction, severe respiratory or cardiac failure.
- •Evidence of severe hematologic abnormality including severe anemia and/or thrombocytopenia.
- •Electrically powered implants (e.g. cochlear implants, neurostimulators) that might be susceptible to radio frequency interference.
- •Unable to completely avoid acetaminophen for duration of study.
- •History of adverse reaction to glucagon (including allergy) besides nausea and vomiting.
- •Established history of allergy or severe reaction to adhesive or tape that must be used in the study.
- •Use oral (e.g. thiazolidinediones, biguanides, sulfonylureas, glitinides, dipeptidyl peptidase-4 (DPP-4) inhibitors, Sodium-glucose Cotransporter-2 (SGLT-2) inhibitors anti-diabetic medications.
- •Any investigational drug use within 30 days prior to enrollment.
- •Pregnant or lactating females.
- •Parents/guardians or subjects who, in the opinion of the Investigator, may be non-compliant with study schedules or procedures.
