Introduction

Recent research has revealed a significant uptick in the prescription of GLP-1 receptor agonists and SGLT2 inhibitors among people with type 1 diabetes, raising several questions about the implications for this patient population. A nationwide cross-sectional analysis conducted by a team at Emory University found that from 2010 to 2023, the percentage of type 1 diabetes patients receiving prescriptions for these medications skyrocketed from 0.7% to 8.3%. The research, published in JAMA, highlights the growing trend towards using these drugs, particularly GLP-1 agonists, even in the absence of FDA approval for use in type 1 diabetes.

Rising Use of GLP-1 and SGLT2 Medications

The data indicates that GLP-1 agonists, known for their weight management capabilities, have been the main driver of this trend. The study reported a significant disparity in patient characteristics, suggesting these medications are being utilized to address additional health needs. For instance, among users of GLP-1 agonists, an alarming 69.4% were classified as obese, compared to just 26.8% in the broader type 1 diabetes demographic. Meanwhile, SGLT2 inhibitor users displayed higher prevalence rates of kidney and cardiovascular diseases, underscoring the multifaceted health concerns these patients face.

Concerns Regarding Off-Label Use

Despite their increasing popularity, concerns about the off-label use of GLP-1 and SGLT2 medications persist. Dr. Hui Shao, who led the study, expressed significant apprehension regarding the limited safety data available for these drugs within the type 1 diabetes population. In fact, European health authorities have withdrawn indications for SGLT2 inhibitors in type 1 diabetes due to potential risks, including euglycemic diabetic ketoacidosis—a dangerous condition that can arise even without elevated blood sugar levels.

Initial Approvals and Growing Advocacy

The initial approval of GLP-1 receptor agonists and SGLT2 inhibitors was primarily for type 2 diabetes management, but advocacy for their use in type 1 has surged due to their additional benefits, including weight loss and improved heart health. Among the medications surveyed in the study, semaglutide—marketed as Ozempic and Wegovy—saw the most remarkable growth in off-label prescriptions, rising from 0.2% in 2018 to 4.4% by 2023.

Data Sources and Insights

The dataset utilized for the research encompassed a staggering 943,456 individuals with type 1 diabetes, extracted from Epic Cosmos, which aggregates health records from roughly 257 million Americans. This extensive reach helps bring to light the trends affecting this demographic across the United States.

Patient Characteristics and Needs

Notably, as the age of newly prescribed patients rises, so do the complexities of their health profiles: those using GLP-1 agonists tended to be older with a higher baseline Body Mass Index (BMI), while SGLT2 inhibitor users exhibited a greater incidence of chronic kidney disease and other cardiovascular comorbidities.

Future Research Directions

In response to the escalating use of these medications, Dr. Shao and his team have secured federal funding to investigate which specific subpopulations of type 1 diabetes patients might benefit safely from GLP-1 receptor agonists and SGLT2 inhibitors. Their ongoing research aims to pinpoint potential benefits and risks, a crucial step toward informed prescribing practices.

Conclusion

As these medications continue to be more widely discussed and prescribed, ongoing scrutiny from researchers, healthcare providers, and regulators is essential to ensure that patients receive safe and effective care tailored to their unique health needs.
