Enavogliflozin Shows Superior Glucose-Lowering Power in Patients with Renal Impairment: Study
In a significant stride toward more effective diabetes management, a newly developed SGLT-2 inhibitor, enavogliflozin, has demonstrated remarkable efficacy in a pooled analysis of two-phase III trials. The study, focusing on patients with type 2 diabetes mellitus based on kidney function, reveals compelling insights into enavogliflozin's superiority over the well-known dapagliflozin.
The study results were published in the journal Cardiovascular Diabetology.
Researchers conducted an extensive analysis, pooling data from 470 patients who participated in two 24-week, randomized, double-blind trials. The trials aimed to evaluate the efficacy and safety of enavogliflozin (0.3 mg/day) in comparison to dapagliflozin (10 mg/day). Notably, the subjects were categorized based on their level of kidney function, distinguishing between mildly reduced and normal estimated glomerular filtration rate (eGFR). Data from 470 patients were included in the analysis, with 235 receiving enavogliflozin (0.3 mg/day) and 235 receiving dapagliflozin (10 mg/day). The patients were categorized based on mildly reduced (60 ≤ eGFR < 90 mL/min/1.73 m², n = 247) or normal eGFR (≥ 90 mL/min/1.73 m², n = 223).
Results:
- In the mildly reduced eGFR group, enavogliflozin demonstrated a significantly greater reduction in adjusted mean change of HbA1c and fasting plasma glucose levels at week 24 compared to dapagliflozin (-0.94% vs. -0.77%, P = 0.0196).
- Notably, the glucose-lowering effect of enavogliflozin was more pronounced when combined with dipeptidyl peptidase-4 inhibitors.
- Enavogliflozin exhibited potent blood glucose-lowering effects regardless of renal function.
- Conversely, dapagliflozin displayed diminishing efficacy with decreasing renal function.
- Enavogliflozin showcased a higher urinary glucose excretion rate in both patient groups.
- Additionally, the homeostatic model assessment revealed a marked decrease in insulin resistance with enavogliflozin.
- Blood pressure, weight loss, and homeostasis model assessment of beta-cell function values did not significantly differ between enavogliflozin and dapagliflozin.
- Adverse events were comparable between the two drugs.
The study concludes that enavogliflozin's glucose-lowering efficacy surpasses that of dapagliflozin, particularly in patients with type 2 diabetes and mild renal function impairment. This superiority is attributed to enavogliflozin's potent urinary glucose excretion-promoting ability. The emergence of such robust SGLT-2 inhibitors holds promise as an attractive option for patients with inadequate glycemic control and decreased renal function.
