In a groundbreaking clinical study published in the journal Nature Metabolism, researchers have unveiled the potential benefits of personalized medical treatment for individuals suffering from type 2 diabetes.
This innovative research, led by Professor Anders Rosengren from the Institute of Neuroscience and Physiology, in collaboration with the Wallenberg Centre for Molecular and Translational Medicine at the University of Gothenburg, marks a significant stride forward in the quest for more effective diabetes management.
The study focused on harnessing the potential of two cutting-edge diabetes medications: GLP1 medicines and SGLT2 inhibitors. With 239 participants representing two distinct subgroups of type 2 diabetes, the findings provide compelling insights into how personalization can revolutionize healthcare practices.
"This is the first clinical study to systematically test whether personalizing medical treatment of type 2 diabetes can work, and how such personalization could work in the healthcare practice," says Professor Rosengren.

Until now, the treatment of type 2 diabetes has followed a one-size-fits-all approach, often overlooking the individual differences in patients' disease characteristics and treatment responses.
The study's subgroups comprised patients with low insulin production and those with good insulin production but high insulin resistance. The results illuminated a striking contrast in treatment efficacy based on the underlying disease mechanisms.
GLP1 Medicines Shine
For patients with impaired insulin production, GLP1 medicines emerged as significantly more effective. The tailored approach yielded promising results, emphasizing the potential of personalized diabetes care. Professor Rosengren comments, "The two medicinal products have different mechanisms of action, and there is a wide variation in how patients respond to them."

Intriguingly, SGLT2 inhibitors proved highly effective for patients with lower BMI and high insulin production, but this was not the case for all. Around 30% of the study's participants found SGLT2 inhibitors to be ineffective. These findings highlight the necessity of customization in diabetes treatment to optimize outcomes.
The Role of Subgroup Classification
The study's most significant contribution lies in its innovative approach to subgroup classification. Patients were randomly assigned to receive either GLP1 medicines or SGLT2 inhibitors, leading to four distinct study groups. Over six months, researchers closely monitored the impact of these treatments on long-term blood sugar levels.

"The group with low insulin production had a significantly better response to GLP1 medicines compared to those whose disease is due to high insulin resistance," Professor Rosengren explains. This revelation underscores the potential for tailoring treatments to individual subgroups, a practice that could enhance the effectiveness of diabetes management.
Beyond Subgroups: A Holistic Approach
However, personalization doesn't end with subgroup classification. The study unveiled that taking into account additional factors such as insulin secretion, insulin resistance, blood pressure, and weight can further refine diabetes treatment. Professor Rosengren emphasizes, "Today, doctors try to find the treatment that works best for the patient, but this presents an opportunity to provide the most effective treatment adapted to the individual disease situation right from the start."

In the pursuit of precision medicine for diabetes, the study suggests the incorporation of a relatively inexpensive and readily available tool – the C-peptide test. Professor Rosengren explains, "The relatively inexpensive C-peptide test could help doctors determine more precisely which medicine a patient should receive for the best effect." This fasting test for insulin production could be seamlessly integrated into clinical practice, offering a valuable resource for optimizing patient care.
The Consequences of Untreated Diabetes
It is crucial to acknowledge that improperly managed diabetes can elevate the risk of serious complications, particularly in specific subgroups. Professor Rosengren underscores the significance of this research, stating, "This provides a valuable tool to improve the clinical management of patients."
By embracing personalized treatment strategies and incorporating diagnostic tools like the C-peptide test, healthcare providers can take a significant step toward reducing the burden of diabetes-related complications.
By tailoring medications to individual subgroups and considering a range of factors, healthcare professionals may soon have the tools they need to provide more effective and precise care to diabetes patients.
As this research paves the way for a brighter future in diabetes management, it underscores the importance of continued exploration and innovation in the field of medicine.
