Big news for people with type 2 diabetes! Tandem Diabetes Care’s Control-IQ+ automated insulin delivery (AID) algorithm is available for people living with type 2 diabetes who are over the age of 18 and on daily insulin therapy. 

Control-IQ+ is available for both people with type 1 diabetes and type 2 diabetes in the U.S.

  • Control-IQ+ is Tandem Diabetes Care’s next-generation AID algorithm used in their t:slim X2 insulin pump, which is paired with a Dexcom continuous glucose monitor (CGM).
  • People with type 1 diabetes have been using the regular Control-IQ algorithm, which is already FDA-approved, but this new version marks a significant step forward for people with type 2 diabetes.
  • Previously, the algorithm was not FDA-approved for type 2 diabetes, but now, Control-IQ+ will bring these benefits to a wider population.

How Control-IQ+ can help people with type 2 diabetes

Managing blood sugar is a big job for people with type 2 diabetes—checking numbers, thinking about insulin, and avoiding highs and lows

Control-IQ+ helps automate much of that process.

  • It’s like having a tiny mathematician inside your Tandem t:slim X2 or Tandem Mobi pump.
    • This system automatically adjusts insulin levels to prevent and respond to blood sugar highs and lows, providing users with more consistent control over their diabetes.
  • With the Control-IQ+ system working 24/7, it helps keep blood sugar levels in range for longer periods of time, promoting better daily energy and overall improved management of type 2 diabetes.
  • For people already using Control-IQ, they will be able to update the software on their pumps to Control IQ+ once it becomes available.

How AID systems work

  • AID systems make insulin pumps smarter by automatically adjusting insulin levels throughout the day. 
  • This prevents dangerous high or low blood sugar events, allowing for a more seamless, hands-off experience in managing type 2 diabetes.

New Study Shows Control-IQ+ Helps People with Type 2 Diabetes

A study published in the New England Journal of Medicine on March 19, 2025, found that Control-IQ+ helps people with type 2 diabetes manage blood sugar more effectively than just using a CGM.

  • Control-IQ+ users had lower A1C than those using only a CGM, dropping 0.9% vs. 0.3%.
    • Those with A1C above 9% saw a 2.3% drop.
  • Users spent 4 more hours daily in the target range.
  • They also used 8 fewer insulin units, while the control group needed 2 more.
  • These benefits showed up in the first week and lasted through the study, working well both day and night.
  • Control-IQ + worked for people of all backgrounds, no matter their age, weight, or diabetes experience.
