What was measured

Ratio of basal:bolus insulin between treatment groups

Analysis population: 1 participant in Non-HCL+Placebo group dropped at baseline and was not analyzed.

Groups in this outcome

HCL and Intensive Management

Participants assigned to HCL group will initially be randomly assigned 1:1 to use either the Tandem t:slim X2 with Control-IQ technology or a Medtronic HCL system (Medtronic 670G 4.0 AHCL (prior to protocol version 5.0) or Medtronic 780G (starting with protocol version 5.0)). This group will receive intensive diabetes management with frequent contacts by study staff with the goal of near-normalization of glucose concentrations. \[Cohort B participants will not receive study drug. Instead, they will be randomized 2:1 to HCL or non-HCL.\] HCL: Hybrid Closed Loop therapy verapamil

Non-HCL and Standard Care

Participants assigned to non-HCL will receive a Dexcom G6 CGM and diabetes management will follow usual care by their personal diabetes health care provider. \[Cohort B participants will not receive study drug. Instead, they will be randomized 2:1 to HCL or non-HCL.\] non-HCL: Usual diabetes care

Verapamil

Verapamil will be taken orally once per day by participants in Cohort A. A dosing scheme will be followed, using 120mg tablets or 60mg half tablets. Whether drug is active or placebo is blinded to both participant and site. \[Cohort B participants will not receive study drug. Instead, they will be randomized 2:1 to HCL or non-HCL.\] verapamil 120mg tablet: verapamil tablet

Placebo

Placebo will be taken orally once per day by participants in Cohort A. A dosing scheme will be followed, using 120mg tablets or 60mg half tablets. Whether drug is active or placebo is blinded to both participant and site. \[Cohort B participants will not receive study drug. Instead, they will be randomized 2:1 to HCL or non-HCL.\] placebo: placebo pill manufactured to mimic verapamil 120mg tablet
