I can tell you that my GF was not allowed by insurance to have both afrezza AND the pump since it was considered a dual prescription for meal time insulin. I can also tell you that she loves being free of the pump. She hated changing sites, and all the scarring it caused in her abdomen.
JDRF did tons of work on the artificial pancreas and they clearly stated that the biggest shortfall was that they needed a faster insulin for mealtime, and they used Afrezza for that purpose.
Here is the stat from MimiMed itself, "An 11% decline in time spent over 180 mg/dl" its clearly not great at preventing mealtime highs.
Best use of the new pump is in combination with Afrezza just as the JDRF did to replace basal shots.
