Trial ID or NCT#
NCT02536950
Status
NOT RECRUITING
Purpose
This is an open-label, non-randomized, pilot study to determine the safety and feasibility of the insulin-only bionic pancreas.
Official Title
An Outpatient Study of Automated Blood Glucose Control With an Insulin-Only Bionic Pancreas
Eligibility Criteria
Ages Eligible for Study: 18 Years to 44 Years
Sexes Eligible for Study: All
Accepts Healthy Volunteers: No
Inclusion Criteria:
- - Type 1 diabetes for at least 1 year - insulin pump for ≥ 6 months - Prescription medication regimen stable for > 1 month - Subject comprehends written English - Female patients who are sexually active must be on acceptable method of contraception e.g. oral contraceptive pill, diaphragm, IUD (Intrauterine Device) - Female patients must have a negative urine pregnancy test - Informed Consent Form signed by the subject - Lives and works within a 60 minute drive-time radius of Stanford University - Willing to remain within a 60 minute drive-time radius of Stanford University during all 3 of the 7-day study arms (21 days) - Have someone over 18 years of age who lives with them,
Exclusion Criteria:
- - Current alcohol abuse (intake averaging > 3 drinks daily in last 30 days), use of marijuana within 1 month of enrollment, or other substance abuse (use within the last 6 months of controlled substances other than marijuana without a prescription) - Subject has a history of diagnosed medical eating disorder - Subject has a history of visual impairment which would not allow subject to participate - Subject has an active skin condition that would affect sensor placement - Subject has adhesive allergies - Subjects requiring an intermediate or long-acting insulin (such as NPH, Neutral Protamine Hagedorn, detemir or glargine) - Subjects requiring other anti-diabetic medications other than insulin (oral or injectable) - Current use of oral/inhaled glucocorticoids or other medications, which in the judgment of the investigator would be a contraindication to participation in the study - Unwilling or unable to refrain from drinking more than 2 drinks in an hour or more than 4 drinks in a day or use of marijuana during the trial - Subject has active Graves' disease - Subjects with inadequately treated thyroid disease or celiac disease - History of liver disease Renal failure on dialysis - Personal history of cystic fibrosis, pancreatitis, pancreatic tumor, or any other pancreatic disease besides type 1 diabetes - Any known history of coronary artery disease - Abnormal EKG (electrocardiogram) consistent with coronary artery disease or increased risk of malignant arrhythmia - Congestive heart failure (established history of congestive heart failure , lower extremity edema, paroxysmal nocturnal dyspnea, or orthopnea) - History of transient ischemic attack (TIA) or stroke - Seizure disorder, history of any non-hypoglycemic seizure within the last two years, or ongoing treatment with anticonvulsants - History of hypoglycemic seizures (grand-mal) or coma in the last year - History of pheochromocytoma: - episodic or treatment refractory (requiring 4 or more medications to achieve normotension) hypertension - paroxysms of tachycardia, pallor, or headache - personal or family history of MEN 2A (multiple endocrine neoplasia), MEN 2B, neurofibromatosis, or von Hippel-Lindau disease - History of adrenal disease or tumor - Hypertension with systolic blood pressure ≥160 mm Hg or diastolic blood pressure ≥100 despite treatment - Untreated or inadequately treated mental illness - Electrically powered implants (e.g. cochlear implants, neurostimulators) that might be susceptible to RF interference - Unable to completely avoid acetaminophen for duration of study - Established history of allergy or severe reaction to adhesive or tape that must be used in the study - History of eating disorder within the last 2 years, such as anorexia, bulimia, or diabulemia or omission of insulin to manipulate weight - History of intentional, inappropriate administration of insulin leading to severe hypoglycemia requiring treatment - Lives in or frequents areas with poor Verizon wireless network coverage (which would prevent remote monitoring) - Any factors that, in the opinion of the site principal investigator or overall principal investigator, would interfere with the safe completion of the study
