Previous data from our clinical trial has demonstrated that the combination of dapagliflozin plus pioglitazone cause robust decrease in the plasma glucose concentration without significant increase in plasma ketone concentration in subjects with T1DM receiving multiple insulin injections or insulin pump. Although patients receiving insulin therapy with pump have participated in the study, none has insulin delivered in automated pump (780 pump) which automatically adjusts the rate of insulin infusion based upon the measured plasma glucose concentration. Although automated insulin pumps have been introduced to practice only last year, they are gaining popularity in the care of T1DM patients worldwide. The aim of this amendment is to demonstrate the efficacy (decrease in HbA1c) and safety (no significant increase in plasma ketone concentration) of combination of dapagliflozin plus pioglitazone in T1DM patients receiving insulin therapy with automated insulin pump.
