Ipragliflozin L-Proline

We conducted a systematic review with pairwise (PMA) and network meta-analyses (NMA) to evaluate sodium-glucose transport protein 2 inhibitor (SGLT2i) effects in patients with both heart failure (HF) and type 2 diabetes mellitus (T2DM). Five databases were searched up to April 15, 2025. Primary outcomes were all-cause mortality (ACM), cardiovascular death (CVD), all-cause hospitalization (ACH), and hospitalization for heart failure (HHF). SGLT2i class effects versus control were assessed via PMA and individual SGLT2i comparative efficacy via NMA plus ranking using p-scores. Seventeen randomized controlled trials (n = 17,809) were included. Arms included canagliflozin (n = 2), dapagliflozin (n = 6), empagliflozin (n = 6), ertugliflozin (n = 1), ipragliflozin (n = 1), sotagliflozin (n = 1), placebo (n = 13), and standard of care (n = 4). Compared to control, SGLT2i significantly reduced ACM (HR 0.87, 95 %CI 0.78 to 0.98, low quality of evidence [QoE]), ACH (HR 0.74, 95 %CI 0.62 to 0.88, high QoE), and HHF (HR 0.70, 95 %CI 0.63 to 0.77, low QoE); but not CVD (HR 0.87, 95 %CI 0.76 to 1.00, very low QoE). Canagliflozin ranked highest in decreasing ACM (p-score = 0.86), CVD (p-score = 0.82), and HHF (p-score = 0.88). In patients with HF and T2DM, SGLT2i class effects include ACM, ACH, and HHF reduction. Among SGLT2i, canagliflozin showed greatest ACM, CVD, and HHF benefit.

Objective Myosteatosis affects the pathogenesis of metabolic dysfunction-associated steatotic liver disease (MASLD) and may be a potential therapeutic target. This study aimed to examine the effects of ipragliflozin (IPR) on myosteatosis in patients with type 2 diabetes mellitus (T2D) and MASLD. Methods Patients were treated with IPR group or a control (CTR) group for 72 weeks in a randomized trial. Changes in myosteatosis of the lumbar skeletal muscles were evaluated using computed tomography. The response of myosteatosis to treatment and the baseline characteristics of the patients were analyzed. Patients 44 participants (IPR group, 23; CTR group, 21) with MASLD complicated by T2D. Results Myosteatosis increased in the CTR group (n=21) but remained unchanged in the IPR group (n=23). The changes were apparent at 24 weeks (p=0.004), but were not significant after 24 weeks. A hierarchical cluster analysis was performed to identify clusters with and without improvement in myosteatosis. The clusters with decreasing intramuscular adipose tissue content (IMAC) at 48 and 72 weeks were not treated, but they had lower visceral fat area and severe liver steatosis at baseline. Improvements in glycemic control and resistance to decreasing abdominal skeletal muscle area from baseline to 24 weeks affected the decrease in IMAC at 48 and 72 weeks. Conclusion Ipragliflozin had a limited effect on skeletal muscle adiposity in patients with T2D and MASLD. Regardless of the treatment, a specific phenotype of adiposity and hepatic steatosis before treatment is associated with the long-term outcomes of myosteatosis. Maintaining skeletal muscle mass and better glycemic control during treatment are essential for the future improvement of myosteatosis.
