Inhaled insulin for controlling blood glucose in patients with diabetes

Diabetes mellitus is a significant worldwide health problem, with the incidence of type 2 diabetes increasing at alarming rates. Insulin resistance and dysregulated blood glucose control are established risk factors for microvascular complications and cardiovascular disease. Despite the recognition of diabetes as a major health issue and the availability of a growing number of medications designed to counteract its detrimental effects, real and perceived barriers remain that prevent patients from achieving optimal blood glucose control. The development and utilization of inhaled insulin as a novel insulin delivery system may positively influence patient treatment adherence and optimal glycemic control, potentially leading to a reduction in cardiovascular complications in patients with diabetes

Progressive Acceleration of Insulin Exposure Over 7 Days of Infusion Set Wear

Insulin exposure varies over 3 days of insulin infusion set (IIS) wear making day-to-day insulin dosing challenging for people with diabetes (PWD). Here we report insulin pharmacodynamic (PD) and pharmacokinetic (PK) data extending these observations to 7 days of IIS wear. PWD (A1C ≤8.5%, C-peptide tmax (P \u3c 0.001), Cmax (P \u3c 0.05), and mean residence time (P \u3c 0.0001). Area under the insulin concentration curve (AUC0–300) declined by ∼24% from days 0 to 7 (P \u3c 0.05). These results confirm/extend previous observations showing progressive acceleration of insulin exposure over IIS wear time. This may have implications for PWD and designers of closed-loop algorithms, although larger studies are necessary to confirm this. The study was registered in clinicaltrials.gov (NCT04398030)

15. Recombinant human hyaluronidase pretreatment of CSII cannula sites provides comparable glycemic control with reduced hypoglycemia in T1DM compared to usual CSII (85-LB)

Recombinant human hyaluronidase (rHuPH20) is FDA-approved to increase dispersion and absorption of injected drugs. In CSII, a single pretreatment of the cannula site with rHuPH20 accelerates exposure and action of bolus doses of rapid analogs for up to 3 days of catheter use
