humulin-s and empagliflozin

To assess whether low doses of empagliflozin as adjunct to hybrid closed-loop therapy improve glycemia compared with placebo in adults with type 1 diabetes (T1D) who are not able to achieve targets with the system alone.. A double-blind crossover randomized controlled trial was performed in adults with suboptimally controlled T1D (HbA1c 7.0-10.5%) who were not able to achieve a target time in range (3.9-10.0 mmol/L) ≥70% after 14 days of hybrid closed-loop therapy. Three 14-day interventions were performed with placebo, 2.5 mg empagliflozin, or 5 mg empagliflozin as adjunct to the McGill artificial pancreas. Participants were assigned at a 1:1:1:1:1:1 ratio with blocked randomization. The primary outcome was time in range (3.9-10.0 mmol/L). Analysis was by intention to treat, and a P value <0.05 was regarded as significant.. A total of 24 participants completed the study (50% male; age 33 ± 14 years; HbA1c 8.1 ± 0.5%). The time in range was 59.0 ± 9.0% for placebo, 71.6 ± 9.7% for 2.5 mg empagliflozin, and 70.2 ± 8.0% for 5 mg empagliflozin (P < 0.0001 between 2.5 mg empagliflozin and placebo and between 5 mg empagliflozin and placebo). Mean daily capillary ketone levels were not different between arms. There were no serious adverse events or cases of diabetic ketoacidosis or severe hypoglycemia in any intervention.. Empagliflozin at 2.5 and 5 mg increased time in range during hybrid closed-loop therapy by 11-13 percentage points compared with placebo in those who otherwise were unable to attain glycemic targets. Future studies are required to assess long-term efficacy and safety.

To evaluate the efficacy and safety of empagliflozin in combination with insulin ± oral antidiabetic drugs (OADs) over 24 weeks, in Chinese patients with type 2 diabetes (T2D) who had insufficient glycaemic control.. This was a randomized, double-blind, placebo-controlled, parallel group, multicentre phase III study. Adult patients with T2D and insufficient glycaemic control who received insulin ± up to two OADs were randomized (1:1:1) to receive empagliflozin 10 or 25 mg, or placebo for 24 weeks. The primary endpoint was change from baseline in HbA1c at week 24.. Of 219 randomized patients, 73 patients were in each treatment group; baseline characteristics were comparable among the groups. There was a significantly larger decrease from baseline in HbA1c (adjusted mean treatment difference -0.99 and -0.98 for in the empagliflozin 10 and 25 mg groups, respectively; P < .0001) with both doses of empagliflozin than with placebo. There were also significantly larger decreases from baseline in fasting plasma glucose, 2-hour postprandial glucose and body weight with both empagliflozin doses than with placebo. Among patients in the empagliflozin 10 mg, 25 mg and placebo groups, 17.8%, 9.6% and 11.0% reported confirmed hypoglycaemic events, respectively (nominal P = .2422 and .7661 in the empagliflozin 10 and 25 mg groups, respectively), and no Clinical Events Committee-confirmed diabetic ketoacidosis events were reported.. In Chinese patients with T2D, empagliflozin combined with insulin ± OADs improved glycaemic control and was well tolerated, without an increased risk of hypoglycaemia.

Sodium-glucose cotransporter-2 inhibitors (SGLT2is), such as empagliflozin, lower blood glucose in type 2 diabetes mellitus and improve cardiorenal outcomes regardless of diabetes presence. Whether SGLT2is exert any effects on the brain's metabolism has not been studied. We conducted a single-arm clinical trial to investigate the effects of once daily administration of oral empagliflozin (25 mg) for 14 days on systemic and brain metabolism in 21 non-diabetics aged 55 years old or older. Empagliflozin lowered circulating insulin and elevated β-hydroxybutyrate over 34-h periods, both following its first administration and after 14 days of daily administration, with minor alterations in glucose homeostasis. Levels of phosphorylated insulin-like growth factor-1 receptor (pIGF-1R), phosphorylated insulin receptor (pIR), phosphorylated-in-tyrosine insulin receptor substrate-1 (pY-IRS-1), and phosphorylated protein kinase B or AKT (pAKT) were increased in extracellular vesicles enriched for neuronal origin (NEVs) following the first empagliflozin administration, but not after 14 days. Our finding of IGF-1R upregulation in NEVs is promising because several post-mortem and epidemiological studies support the idea that upregulation of IGF signaling may protect against Alzheimer's disease (AD). Moreover, our finding showing activation of insulin signaling and, in particular, the canonical pathway (pIR, pY-IRS-1, pAKT) in NEVs is important because such changes have been repeatedly associated with neuronal survival. Using brain magnetic resonance spectroscopy (MRS), we detected decreased concentrations of the excitatory neurotransmitter glutamate and its precursor glutamine after empagliflozin administration. This finding is also encouraging since glutamatergic excitotoxicity has long been implicated in AD pathology. Overall, our findings may motivate the repurposing of SGLT2is for use in AD and other, related diseases that are characterized by downregulation of IGF-1/insulin signaling in neurons and excitotoxicity.
