Control-IQ+: Bridging the Gap in Automated Insulin Delivery

Perhaps one of the most significant announcements came from Tandem Diabetes Care, a name synonymous with innovation in insulin pump technology. They unveiled their next-generation algorithm, Control-IQ+, and it’s a genuine game-changer. What makes it so revolutionary? Well, beyond its inherent sophistication, the system is now available for both type 1 and type 2 diabetes patients, marking a monumental expansion in its applicability.

For years, advanced AID systems were primarily focused on the type 1 population, and for good reason. Type 1 diabetes demands constant vigilance, precise insulin dosing, and often, an intensive daily routine that can feel like a full-time job. But we can’t forget, type 2 diabetes affects a far larger demographic, and while its management often involves different strategies, the burden of glycemic control is no less significant. Think about it: a vast, underserved population grappling with the complexities of blood sugar management can now potentially benefit from the same level of sophisticated automation. That’s huge, isn’t it?

Clinical studies presented at the conference really underscored the system’s efficacy. Imagine this: individuals with type 2 diabetes using Control-IQ+ experienced a remarkable 24% increase in time in range (TIR), moving from an average of 48% to a much healthier 64% over just 13 weeks. For those not deep in the diabetes world, ‘time in range’ means the percentage of time a person’s blood glucose levels remain within a healthy target, typically between 3.9 and 10.0 mmol/L. A higher TIR directly correlates with fewer complications, improved well-being, and a better quality of life. An increase of 24% isn’t just a number; it translates to weeks, even months, of healthier glucose levels over a year, drastically reducing the roller-coaster effect many patients endure.

And there’s more. The same study revealed a significant 0.9% reduction in A1C levels, dropping from an average of 8.2% to 7.3%. An A1C reduction of this magnitude, particularly in the type 2 population, is highly commendable and speaks volumes about the algorithm’s power to enhance glycemic control. We’re talking about tangible improvements that can delay or prevent serious long-term complications like neuropathy, retinopathy, and kidney disease. It’s an outcome that dramatically eases the daily burden of diabetes management, offering patients not just better numbers, but genuine peace of mind.

Control-IQ+ employs a predictive algorithm that constantly analyzes continuous glucose monitoring (CGM) data. It learns an individual’s unique glucose patterns, anticipating highs and lows before they even fully manifest. Then, it automatically adjusts insulin delivery every five minutes, fine-tuning basal rates and delivering automatic correction boluses as needed. It’s like having a highly skilled, incredibly patient endocrinologist continually making micro-adjustments in real-time, twenty-four hours a day. Honestly, who wouldn’t want that kind of support?

Sharper Vision: The Latest in Continuous Glucose Monitoring

Continuous Glucose Monitoring (CGM) has, without a doubt, revolutionized diabetes care over the past decade. It’s shifted us from blind spots and guesswork to real-time insights. At ATTD 2025, Dexcom, a perennial leader in this space, unveiled its new 15-day G7 sensor, a significant upgrade that builds on an already impressive foundation. If you’ve been a CGM user, you’ll know that every extra day of wear time feels like a small victory.

Extending sensor wear to 15 days from the previous 10 days for the G6, or even the initial 10-day G7, isn’t just about convenience—though that’s certainly a huge plus, reducing the frequency of uncomfortable sensor changes. It also means less waste, potentially lower overall costs, and a more seamless integration into daily life. Think about traveling, or just a busy week at work; one less thing to worry about really helps.

Beyond convenience, accuracy remains paramount. Dexcom’s G7 boasts an impressive Mean Absolute Relative Difference (MARD) of 8.0%. For those unfamiliar, MARD is the gold standard for measuring CGM accuracy; lower numbers are better, indicating closer agreement between CGM readings and laboratory blood glucose values. An 8.0% MARD places the G7 squarely among the most accurate sensors on the market, directly comparable to its formidable competitor, the Abbott Freestyle Libre 3, which also showcases exceptional accuracy. This fierce competition in the accuracy stakes ultimately benefits the user, pushing manufacturers to continuously refine their technology.

But Dexcom isn’t just focusing on the sensor itself; they’re keenly aware of the need for a cohesive, interconnected diabetes ecosystem. The conference highlighted Dexcom’s integration with smart insulin delivery systems like the NovoPen 6 and NovoPen Echo Plus, particularly noting their availability in Germany. These aren’t just regular insulin pens; they’re ‘smart’ pens that connect via Bluetooth, logging insulin doses, times, and types directly into an app. When this data seamlessly syncs with CGM readings, it creates a much more complete picture for both the patient and their healthcare provider.

Imagine: your CGM data shows a rising trend, and your smart pen records your last bolus dose. An integrated app could then provide personalized recommendations, or at the very least, give you a clearer understanding of how your body responds to insulin, food, and activity. This kind of integration is the future, knitting together disparate pieces of technology into a powerful, unified management system. It’s about empowering patients with actionable insights, not just raw data, and that’s a crucial distinction.

The Ketone Revolution: CKM’s Rise to Prominence

One of the most intriguing and, frankly, vital developments at ATTD 2025 was the heightened emphasis on continuous ketone monitoring (CKM) systems. For anyone living with type 1 diabetes, or even those with type 2 on certain medications, the looming threat of diabetic ketoacidosis (DKA) is very real. DKA is a serious, life-threatening complication where the body produces high levels of blood acids called ketones, typically when there isn’t enough insulin to allow glucose into cells for energy. It can lead to severe dehydration, confusion, coma, and even death if not addressed rapidly.

Currently, ketone monitoring often relies on finger-prick blood tests or urine strips, which are reactive, not proactive. They tell you about a problem after it’s started. CKM systems, however, aim to detect rising ketone levels in real-time, acting as an early warning system. Imagine receiving an alert on your phone: ‘Ketones are rising, please check your blood glucose and consider a correction.’ This proactive approach could quite literally be a lifesaver, allowing users to take corrective actions—like administering insulin or drinking fluids—long before DKA becomes critical. The peace of mind that comes with such a system really can’t be overstated.

Beyond DKA prevention, CKM has another critical role to play: facilitating the safe use of SGLT inhibitors. This class of drugs, including medications like Farxiga and Jardiance, has proven incredibly beneficial for heart and kidney complications in both type 1 and type 2 diabetes. However, they come with a known, albeit rare, increased risk of euglycemic DKA—meaning DKA can occur even with near-normal blood glucose levels. This particular risk has often limited their use in people with type 1 diabetes, despite their proven cardiovascular and renal protective effects.

CKM could unlock the full potential of SGLT inhibitors for a wider population. If a patient on an SGLT inhibitor is continuously monitored for ketones, they can be alerted at the first sign of trouble, mitigating the risk of DKA and allowing them to benefit from these crucial medications. It’s a fantastic example of how one technological advancement can open doors for another, improving overall patient outcomes significantly. The medical community, keenly aware of CKM’s potential, is actively working on international consensus guidelines to ensure its effective and standardized integration into diabetes care, which is a necessary step before widespread adoption. It’s a thoughtful approach, ensuring the technology is used wisely and safely.

AI at the Helm: Intelligent Insulin Therapy

The power of artificial intelligence (AI) is permeating every facet of our lives, and diabetes management is certainly no exception. ATTD 2025 showcased how AI is rapidly enhancing insulin therapy, moving us closer to truly personalized and adaptive treatment strategies. One standout example was the Adaptive Basal-Bolus Advisor (ABBA), an AI-driven system that demonstrated remarkable improvements.

ABBA isn’t just crunching numbers; it’s learning. It continuously analyzes an individual’s CGM data, activity levels, meal patterns, and insulin sensitivity over time. This learning allows it to predict insulin needs more accurately and recommend personalized basal and bolus doses. Studies presented showed that individuals with both type 1 and type 2 diabetes using ABBA experienced improved time-in-range and, importantly, reduced glycemic variability. Glycemic variability refers to the fluctuations in blood glucose levels, and while high and low extremes are dangerous, even frequent, smaller swings can contribute to complications and impact a person’s well-being. By smoothing out these peaks and valleys, AI offers a more stable, predictable glycemic profile.

This personalized approach to insulin dosing is where AI truly shines. Traditional insulin dosing often involves generalized guidelines or manual adjustments based on past readings. AI, on the other hand, constantly adapts to individual responses, factoring in everything from a stressful meeting to an impromptu gym session. It’s like having a personal data scientist optimizing your insulin regimen in real-time, taking into account the myriad variables that impact blood sugar. I’m personally quite excited about this; it could reduce so much of the mental load currently placed on patients.

Beyond direct dosing advice, AI’s potential in diabetes is vast. We’re already seeing applications in predictive analytics for identifying individuals at risk of developing diabetes, early detection of complications, and optimizing clinic workflows. Imagine AI systems sifting through vast amounts of patient data to identify subtle patterns that human eyes might miss, leading to earlier interventions and better long-term outcomes. Of course, this also brings up important discussions around data privacy and ethical AI development, conversations that are happening concurrently with the technological advancements.

Sweat and Sensors: Exercise and CGM’s Potent Partnership

Sometimes, the simplest solutions, amplified by technology, can be the most powerful. Dr. Mike Riddell, a renowned expert in exercise physiology and diabetes, presented compelling evidence that integrating continuous glucose monitoring data with physical activity can be as effective as pharmacological interventions in managing type 2 diabetes. That’s a pretty bold claim, isn’t it? But the data backs it up.

The ACT-ONE study, a cornerstone of his presentation, demonstrated that using CGM data to intelligently guide exercise planning dramatically improved time in range and insulin sensitivity. How does this work in practice? Well, with CGM, individuals can see how different types and intensities of exercise impact their blood glucose in real-time. This insight allows for informed decision-making: perhaps a small carb snack before a longer run to prevent a low, or a brief burst of high-intensity activity to bring down a stubborn high. It means understanding your body’s unique response to movement, rather than guessing.

For someone with type 2 diabetes, this personalized approach to lifestyle intervention is incredibly empowering. We’ve always known exercise is crucial, but knowing when and how to exercise for optimal glycemic control, guided by real-time data, is a game-changer. It shifts exercise from a generic recommendation to a precisely calibrated therapeutic tool. It highlights how technology can move beyond just medication, truly empowering individuals to take an active role in their health management. This personalized approach often leads to greater adherence and better long-term results, something we’ve struggled with in traditional health messaging.

Style Meets Substance: Insulin Delivery Devices Reinvented

Beyond the algorithms and the sensors, the physical devices we rely on daily are also undergoing impressive transformations. The Kaleido 2 insulin pump, introduced at ATTD 2025, perfectly embodies this blend of advanced functionality and user-centric design. It’s 10% smaller than its predecessor, which might not sound like much, but when you’re wearing a device 24/7, every millimeter counts for comfort and discretion. And speaking of discretion, it features a sleek design with a matte finish, available in a palette of six appealing colors. For many, a medical device is a constant, visible part of their life, so why shouldn’t it be aesthetically pleasing and align with their personal style? It makes a difference, believe me.

But Kaleido 2 isn’t just about looks. It’s packed with smart features. For instance, it comes equipped with an accelerometer, opening up possibilities for integrated activity tracking. Imagine your pump understanding your movement patterns and potentially adjusting insulin delivery based on your physical exertion. This could mean fewer manual adjustments during or after exercise, reducing the risk of hypo or hyperglycemia. It’s a subtle but powerful step towards a more autonomous system.

Furthermore, it includes a temperature sensor, a thoughtful addition designed to protect insulin. Insulin is a delicate protein and can degrade if exposed to extreme temperatures, losing its potency. This sensor provides a crucial safeguard, alerting users if the insulin reservoir is nearing an unsafe temperature, thereby ensuring the medication remains effective. It’s these kinds of detailed, practical innovations that make a real difference in the day-to-day lives of users.

Beyond Kaleido 2, the broader trend in insulin delivery devices is clear: smaller, smarter, and more integrated. Patch pumps are becoming ever more discreet, and smart insulin pens are gaining traction, allowing for precise dose logging and connectivity to health apps. The goal is clear: to make insulin delivery less intrusive, more intuitive, and ultimately, more effective, fitting seamlessly into one’s life rather than dictating it.

A Glimpse into Tomorrow, Today

The developments showcased at ATTD 2025 truly illustrate a dynamic and rapidly evolving landscape in diabetes care. We’re witnessing a pivotal shift towards technologies that are increasingly personalized, seamlessly integrated, and intuitively designed to enhance not just glycemic control, but the overall quality of life for individuals with diabetes. The days of siloed devices and manual guesswork are slowly but surely fading into the past.

What we’re seeing is a future where technology doesn’t just manage a condition; it anticipates needs, prevents crises, and empowers individuals to live fuller, healthier lives with less burden. It’s a compelling vision, isn’t it? The journey toward a ‘cure’ might still be ongoing, but these advanced technologies are certainly closing the loop, offering individuals with diabetes more effective, convenient, and truly personalized management options than ever before. It leaves me incredibly optimistic for what the next few years will bring. The future, for diabetes management, really is now.
