Insights
Cardio-kidney-metabolic therapies, including GLP-1RA and SGLT2i, show promise for managing Type 1 diabetes with chronic kidney disease. These treatments were associated with reduced albuminuria and were found to be safe in a large patient database.
Area of Science:
- Endocrinology and Metabolism
- Nephrology
- Cardiology
Background:
- Type 1 diabetes (T1D) is frequently complicated by kidney and cardiovascular diseases.
- Novel cardio-kidney-metabolic (CKM) therapies, such as GLP-1 receptor agonists (GLP-1RA) and SGLT2 inhibitors (SGLT2i), offer potential benefits.
- Limited data exist on CKM therapy use and efficacy in T1D patients with chronic kidney disease (CKD).
Purpose of the Study:
- To investigate the utilization, efficacy, and safety of CKM therapies in T1D patients with CKD.
- To assess the impact of CKM therapies on kidney function, specifically urinary albumin-to-creatinine ratio (UACR).
- To evaluate the risk of adverse events like hypoglycemia and diabetic ketoacidosis with CKM therapy use.
Main Methods:
- Analysis of a large US de-identified database (Optum Market Clarity) from 2016-2023.
- Inclusion of adult T1D patients with CKD who initiated CKM therapy.
- Propensity score matching to compare CKM therapy users with non-users; assessment of UACR changes, hypoglycemia, and diabetic ketoacidosis rates.
Main Results:
- CKM therapy was utilized by over 10% of T1D patients with CKD.
- Patients on CKM therapy achieved a 30% or greater reduction in UACR more quickly than controls (HR 0.76, p=0.0158).
- No significant increase in hypoglycemia or diabetic ketoacidosis rates was observed in the CKM therapy group.
Conclusions:
- CKM therapies are frequently used in T1D patients with CKD and are associated with significant UACR reduction.
- The use of CKM therapies in this population appears safe, with no increased risk of major adverse events.
- These real-world findings support the need for randomized clinical trials to confirm the benefits of CKM therapies in T1D and CKD.
Aims:
Kidney and cardiovascular diseases are highly prevalent among patients with Type 1 diabetes. To date, no randomised clinical trial has reported on the impact of novel cardio-kidney-metabolic (CKM) therapies (GLP-1RA and SGLT2i) on kidney function in this population. We investigated a large US database to determine whether CKM therapies were used, beneficial and safe among patients with Type 1 diabetes and chronic kidney disease (CKD).
Materials And Methods:
Adults with Type 1 diabetes in Optum's de-identified Market Clarity database, consisting of claims and electronic medical records data, between January 1, 2016, and December 31, 2023, were included. Patients who had their first CKM therapy prescription during the study period were propensity score-matched to those not on CKM therapy. The 253 patients with sufficient data to assess changes in urinary albumin-to-creatinine ratio (UACR) were included in the analyses. Rates of hypoglycaemia and diabetic ketoacidosis were also assessed.
Results:
CKM therapy was used by more than 10% of the patients with Type 1 diabetes and CKD. At baseline, average age was 52 years, HbA1c 8.1%, eGFR 77 mL/min/1.73 m2. UACR median was 60.8 mg/g. Time to 30% or more UACR reduction was shorter among patients on CKM therapy versus controls [HR 0.76 (CI 0.61-0.95), p = 0.0158]. Rates of hypoglycaemia and diabetic ketoacidosis were not increased among patients on CKM therapy.
Conclusions:
CKM therapy was frequently used in patients with Type 1 diabetes and CKD, associated with UACR reduction and safe. These clinically relevant data warrant confirmation in randomised clinical trials.
