ADA 2024 Day 2

The American Diabetes Association’s 84th Scientific Sessions is here! Scientists will present the latest type 1 diabetes (T1D) research, from early detection to glucose control to complications, all with the goal of improving lives for the T1D community.

  1. In November 2022, the FDA approved Tzield™ (teplizumab-mzwv) for use in delaying the onset of clinical T1D. With the availability of a treatment option for people with Stage 2 T1D, the field has changed its outlook on delay and prevention and navigating pediatric T1D, especially in the early stages. Annette-Gabriele Ziegler, M.D., presented on several screening programs in Europe, including Fr1da, which has screened 200,000+ pediatric participants and found that it significantly reduces DKA onset at clinical diagnosis, and GPPAD, which identifies infants with an elevated genetic risk of developing T1D and enrolls them in primary prevention clinical trials. Andrea Steck, M.D., highlighted the value of CGM-based metrics in evaluating T1D risk and R. Brett McQueen, Ph.D., discussed the economics of early detection.

At-risk, or Stage 2 T1D, means that a person exhibited 2+ T1D-related autoantibodies—antibodies against one’s own self—and their blood glucose is starting to be abnormal, but they are not yet insulin dependent. When someone becomes insulin-dependent, they are in stage 3 T1D.


  • We got updates on several automated insulin delivery (AID), or artificial pancreas, systems, including the:
    • Medtronic MiniMed 780G, especially the importance of initiating it as soon as possible following diagnosis (which is now recommended in the ADA Standards of Care for both children and adults), citing the CLVer trial, which found clinically meaningful and sustained improvements in blood sugar management following early AID initiation.
    • Medtronic MiniMed 780G in high-risk youth with T1D, with 80 participants aged 7-25 years, who demonstrated an average HbA1c reduction of 2.5% (from an average baseline HbA1c of 10.5% to 8%), improvement in time-in-range, and a reduction in low blood sugar events.
    • Tandem Mobi among early pediatric and adult adopters.
    • Sequel Med Tech’s twist AID system, which was FDA-cleared for people with T1D aged 2+ in March 2024. The system uses the DEKA Loop algorithm, which is based on the FDA cleared Tidepool Loop (iAGC) and is intended for use with compatible interoperable continuous glucose monitors (iCGMs). Sequel is Tidepool’s first publicly announced insulin delivery device partner with an FDA-cleared system that will integrate Tidepool Loop.
  • In therapy, the full INHALE-3 results demonstrated the non-inferiority of inhaled insulin (Afrezza) used with insulin degludec compared to usual care. Baseline HbA1c was 7.6% across groups, and, on average, HbA1c in both groups remained stable from baseline to 17 weeks. Overall, 30% of the inhaled insulin group reached <7.0% A1c at 17 weeks compared to only 17% of the usual care group.
