Pilot Study Assessing Insulin Pump Therapy in Type 2 Diabetes

20. september 2017 oppdatert av: Animas Corporation
16-week, open-label, multi-center pilot study. Insulin pump naïve subjects with type 2 diabetes who are not achieving glycemic targets (screening A1C ≥ 7.0%) on an established regimen of either: 1) ≥ 2 OAs (Cohort A), 2) basal insulin ± OAs (Cohort B), or 3) basal-bolus insulin ± OAs (Cohort C) will initiate basal-bolus therapy with an insulin pump using a rapid-acting insulin analog.

  5. Has a body mass index (BMI) ≥ 25 kg/m2 and ≤ 40 kg/m2;
  6. Is treated with either ≥ 2 oral antidiabetic agents (OA) or basal insulin ± OA(s) or basal-bolus insulin ± OA(s) for at least 3 months (Subjects may also be treated with exenatide [Byetta] or pramlintide [Symlin].
  7. If on concomitant metformin, has serum creatinine < 1.5 mg/dL (male) or <1.4 mg/dL (female);
  8. If female, has a negative urine pregnancy test

Exclusion Criteria:

  1. Has experienced recurrent severe hypoglycemia (> 2 episodes) requiring assistance during the past 6 months;
  2. Has clinical cardiovascular disease (CVD) as evidenced by prior myocardial infarction, stroke, arterial revascularization and/or angina with ischemic changes on ECG at rest, changes on graded exercise test, or positive cardiac imaging test results;
  3. Has abnormalities on the screening (Visit 1) 12-lead ECG that are deemed by the investigator to be clinically significant;

Hva måler studien?

Primære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Insulin doses at Week 16
Tidsramme: Week 16
To evaluate insulin doses after 16 weeks of insulin pump therapy aimed at achieving normal or near-normal glycemic control in subjects with type 2 diabetes.This included the total daily insulin dose, basal and bolus insulin doses.
Week 16
Ratio of Basal-to-Bolus Insulin Dose at Week 16

16 weeks
Number of daily basal rates at Week 16
Tidsramme: Week 16

7 point profile
Tidsramme: Week 16
Self-monitored 7-point profiles were compared at baseline and Week 16 for each cohort and all cohorts combined.

CGM Glucose Ranges - Percent of Measurements
Tidsramme: End of study
The percent of glucose values within the target range of 70-180 mg/dL, as measured by CGM
End of study
Body Weight
Tidsramme: Week 16
Weight change was evaluated at Week 16 for each cohort and all cohorts combined.
Week 16
Hypoglycemia
Tidsramme: Week 16
The incidence (percent of patients with at least one episode of hypoglycemia) of minor hypoglycemia was evaluated respectively. Minor hypoglycemia was defined as symptoms consistent with hypoglycemia that either resolved spontaneously or upon self-treatment with oral carbohydrate. Severe hypoglycemia referred to symptoms consistent with hypoglycemia during which the patient required the assistance of another individual and was associated with a documented glucose concentration less than 56 mg/dL or prompt recovery after oral carbohydrate, intravenous glucose, or glucagon.
Week 16
Change from baseline to week 16 in Patient Reported Outcomes (PROs)
Tidsramme: Week 16
PROs were assessed at Baseline, Wk 8 (except for EQ-5D) and Wk 16, including EuroQol-5 Dimensions (EQ-5D) (Generic health-related QoL), Diabetes Symptom Checklist-Revised (DSC-R) (Diabetes-specific QoL), and Insulin Delivery System Rating Questionnaire (IDSRQ) (Treatment Satisfaction with insulin delivery system)
