[PMID: 37984730 DOI: 10.1016/j.eprac.2023.11.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Revised: 11/13/2023] [Accepted: 11/14/2023] [Indexed: 11/22/2023]
Abstract
BACKGROUND Once-weekly basal insulin icodec has been tested in clinical trials for efficacy and safety over currently available glargine-100 and degludec in different clinical settings for type 2 diabetes. We performed this meta-analysis to evaluate its overall safety and efficacy as compared to glargine-100 and degludec (nonicodec), from all available randomized controlled trials. METHODS Seven trials comparing once-daily basal insulin analogs to once-weekly basal insulin icodec were included. Based on available information, outcomes in terms of HbA1c, fasting plasma glucose reduction, and increase in time in range (TIR) were compared. Side-effects were compared for overall hypoglycemia, severe hypoglycemia, and weight gain. The pooled effect size for continuously distributed data was measured as a reduction in "estimated differences in mean (with 95% CI)." For categorical data, the pooled effect size was measured as the Mantel-Haenszel risk ratio (with 95% CI). RESULTS Analyzing against the nonicodec comparators together, the "estimated mean changes" in HbA1c and fasting plasma glucose favoring icodec were -0.22% (-0.35, -0.10) and -1.59 mg% (-9.26, 6.08) respectively. The "estimated mean increment" in weight for icodec was 0.64 kg (0.61, 0.67). The "estimated mean percentage" increment in TIR for icodec was 4.24% (2.99, 5.49). The Mantel-Haenszel risk ratios for all hypoglycemic events and severe hypoglycemia for icodec were 1.24 (1.02, 1.50) (P = .03) and 0.81 (0.31, 2.08) (P is not significant), respectively, suggesting a 24% increased incidence of all hypoglycemia with icodec. CONCLUSION Once-weekly basal insulin icodec as compared to once-daily basal insulin analogs had a slight increase in the risk of overall hypoglycemia and weight gain, without any difference in severe hypoglycemia, with similar glycemic control (in terms of fasting plasma glucose, HbA1c, and TIR).

Abstract
INTRODUCTION Fixed ratio combination of insulin degludec and liraglutide (IDegLira) represents an option to revise inappropriate therapies in patients with poorly controlled type 2 diabetes. This study aimed to assess the pattern of use and 1-year effectiveness of IDegLira. METHODS A retrospective chart review was performed to assess changes in glycated hemoglobin (HbA1c) (primary endpoint), fasting blood glucose (FBG), body weight, estimated glomerular filtration rate (eGFR), and lipid profile following IDegLira initiation. Previous versus concomitant diabetes treatments were also compared. RESULTS Overall, 87 patients (mean age 73.9 ± 9.2 years, diabetes duration 18.2 ± 6.7 years, 62.1% men, HbA1c 8.3 ± 1.3%, BMI 30.4 ± 5.5 kg/m2) initiated IDegLira. Previously, 21.8% of patients were treated with oral hypoglycemic agents (OHA group), 47.1% with basal insulin ± OHA (BOT group), 5.8% with GLP-1 RA ± basal insulin (GLP1-RA group), and 25.3% with basal-bolus schemes (BB group). At the first prescription of IDegLira, secretagogues and schemes including two or more OHA were substantially reduced, leaving metformin as the most prevalent OHA (81.6%) used in combination with IDegLira. Starting dose of IDegLira ranged from 18.7 ± 3.1 U (OHA group) to 24.1 ± 4.4 U (BB group). After 1 year, HbA1c was significantly reduced by 1.25% (95% CI - 1.48; - 1.03), FBG by 52.9 mg/dl, and body weight by 2.0 kg. Also, eGFR levels and lipid profile significantly improved. No severe hypoglycemia occurred. CONCLUSION It is possible to proactively review suboptimal or inappropriate diabetes treatment according to the most recent guidelines. Results suggest that initiation of IDegLira was associated with a reduction in drugs to be administered daily and relevant improvements in clinical outcomes.

Real-world Clinical Effectiveness on Glycaemic Parameters, Safety and Additional Benefits of Glargine U300 (Toujeo®) Initiation after Oral Antidiabetic Drug Failure in Insulin-naïve Patients with type 2 Diabetes Mellitus. Indian J Endocrinol Metab 2023; 27:426-430. [PMID: 38107728 PMCID: PMC10723600 DOI: 10.4103/ijem.ijem_57_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Revised: 03/25/2023] [Accepted: 04/22/2023] [Indexed: 12/19/2023] Open
Abstract
Background Several studies have proved the advantages of second-generation insulin analogs in lowering intra-individual variability in plasma insulin levels, flexibility in dosing, a sustained glucose-lowering effect, and decreasing the risk of hypoglycemia. Glargine 300 is one of the newer second-generation basal insulin analogs to have been approved for both type 1 and 2 diabetes. The present study aims to assess the real-world clinical effectiveness and safety of Glargine U300 (Toujeo®) initiation after oral antidiabetic drug failure in insulin-naïve patients with T2DM. Methods A prospective, observational study was conducted where participants were interviewed regarding their basic demographics, body weight, and treatment details. Glycemic parameters (HbA1C%, Fasting Plasma Glucose, and Post Prandial Blood Glucose) were observed in the initial 6 months, and changes were noted and compared. Any hypoglycemic events or other complications were also noted. Data collected were statistically analyzed. Results The study included a total of 188 patients. Treatment with glargine 300 significantly reduced the mean HbA1C level from 9.78% at baseline to 7.90% at the end of 6 months of treatment (p < 0.001). 10.60% of patients achieved the glycemic target of ≤7.0% by the end of 6 months, while only 6.90% were within the target range at baseline. Similarly, significant reduction in FPG was observed at the end of 6 months treatment period with Glargine U300. A significant increase in dose requirement was observed throughout the study phase (p < 0.001). Incidence of hypoglycemia was noted in 2.12% of subjects. Conclusion The lower incidence statistics of hypoglycemia coupled with sustained positive glycemic effects, stands out to be a prominent advantage of Glargine U300 over its other congeners.

Diabet Med 2023; 40:e15112. [PMID: 37035994 DOI: 10.1111/dme.15112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 04/04/2023] [Accepted: 04/07/2023] [Indexed: 04/11/2023]
Abstract
AIMS A cost-effectiveness analysis was conducted to compare insulin glargine 300 U/mL (Gla-300) versus insulin degludec 100 U/mL (IDeg-100) in insulin-naïve adults with type 2 diabetes (T2D) sub-optimally controlled with oral anti-diabetic drugs (OADs). METHODS The BRAVO diabetes model was used to assess costs and outcomes for once-daily Gla-300 versus once-daily IDeg-100 from a US healthcare sector perspective. Baseline clinical data were based on BRIGHT, a 24-week, non-inferiority, randomised control trial comparing Gla-300 and IDeg-100 in adults with T2D sub-optimally controlled with OADs (with or without glucagon-like peptide-1 receptor agonists). Treatment costs were based on doses observed in BRIGHT as well as net prices. Costs associated with complications were based on published literature. Lifetime costs (US$) and quality-adjusted life-years (QALYs) were predicted and used to calculate incremental cost-effectiveness ratio estimates; extensive scenario and sensitivity analyses were conducted. RESULTS Overall lifetime medical costs were estimated to be $327,904 and $330,154 for people receiving Gla-300 and IDeg-100, respectively; insulin costs were $43,477 and $44,367, respectively. People receiving Gla-300 gained 8.024 QALYs and 18.55 life-years, while people receiving IDeg-100 gained 7.997 QALYs and 18.52 life-years. Because Gla-300 was associated with a cost-saving of $2250 and 0.027 additional QALYs, it was considered to be dominant compared with IDeg-100. Results of the scenario and sensitivity analyses confirmed the robustness of the base case results. CONCLUSION Gla-300 was the dominant treatment option compared with IDeg-100 based on the willingness-to-pay threshold of $50,000/QALY. Results remained robust against a wide range of alternative assumptions on key parameters.

J Med Econ 2023; 26:1469-1478.

Abstract
AIMS This study aimed to evaluate the value and affordability of insulin glargine 300 U/mL (Gla-300) in a budget impact model from a United States (U.S.) payer perspective by leveraging recent real-world evidence (RWE) studies and incorporating the recent insulin price caps where applicable. MATERIALS AND METHODS An economic model for a hypothetical one million U.S. health-plan population was developed to assess the budgetary impact of therapeutic interchanges in either direction between the two long- and longer-acting basal insulins (BIs) for patients with type 2 diabetes over a three-year model horizon. The utilization of long-acting BIs, longer-acting BIs, biosimilar BIs, and insulin degludec (IDeg-100) were informed by IQVIA data and internal forecasting at Sanofi. The DELIVER-2 and DELIVER-naïve studies provided healthcare resource utilization (HCRU) parameters. In the model base case, 24% of patients switched from long-acting BIs to insulin glargine biosimilars, IDeg-100, and other longer-acting BIs (Gla-300) by projected year 3. RESULTS The base case total costs were $10,145 per patient per year (PPPY) in year 3 for the cumulative population. When all patients switched to Gla-300, the total costs in year 3 were $8,799, reflecting a net savings of -$660 PPPY compared to the budget increase of $686 PPPY in the base case. However, the longer-acting to long-acting BIs reversal scenario demonstrated a budgetary decrease of $676 PPPY over the model horizon. The reduction in incremental PPPY cost of $93 was observed using net drug costs rather than wholesale acquisition costs (WAC). LIMITATIONS The market shares for years 1-3 were based on expectations supported by the clinicians' expert opinions and were not obtained from real-world data. CONCLUSIONS The economic value of increased utilization of Gla-300 was driven by the reduction in HCRU, costs and market shares assumptions. Budgetary reductions were achieved by switching patients from long-acting BIs to Gla-300.

Abstract
BACKGROUND Diabetic kidney disease is the leading cause of chronic kidney disease (CKD) and end-stage kidney disease (ESKD) worldwide. ESKD has a high prevalence in patients with diabetes mellitus (DM). CKD increases the chances of hypoglycaemia by different mechanisms, causes insulin resistance and a decrease in insulin metabolism. Both the "Kidney Disease: Improving Global Outcomes" (KDIGO) and "American Diabetes Association" (ADA) guidelines recommend the use of insulin as part of treatment, but the type of basal insulin is not specified. METHODS We reviewed the literature to determine whether first- and second-generation basal insulins are effective and safe in CKD patients. We reviewed specific pivotal studies conducted by pharmaceutical laboratories, as well as independent studies. CONCLUSIONS Basal insulins are safe and effective in patients with CKD and diabetes mellitus but we do not have specific studies. Given that CKD is one of the main complications of type 2 DM, and insulin specific treatment in the final stages, the absence of studies is striking. Real-life data are also important since trials such as pivotal studies do not fully represent actual patients. Treatment should be individualized until we have specific trials in this type of population.

Abstract
Treatment with basal insulins is a fundamental part of management in many patients with type 2 diabetes mellitus. Multiple management schemes may be indicated in these individuals, for example, the use of oral antihyperglycemic agents with basal insulins (basal-supported oral therapy) or the combinations of basal insulins with glucagon-like peptide-1 receptor agonists; each of these strategies makes it easier to achieve glycemic control goals. A basic knowledge of the physiology, pharmacodynamic and pharmacokinetic aspects of the different basal insulins is essential to achieve treatment goals and compliance. This review addresses the principles of management with basal insulins.

Abstract
Therapeutic preparations of insulin often contain phenolic molecules, which can impact both pharmacokinetics and shelf life. Thus, understanding the interactions of insulin and phenolic molecules can aid in designing improved therapeutics. In this study, we use molecular dynamics to investigate phenol release from the insulin hexamer. Leveraging recent advances in methods for analyzing molecular dynamics data, we expand on existing simulation studies to identify and quantitatively characterize six phenol binding/unbinding pathways for wild-type and A10 Ile → Val and B13 Glu → Gln mutant insulins. A number of these pathways involve large-scale opening of the primary escape channel, suggesting that the hexamer is much more dynamic than previously appreciated. We show that phenol unbinding is a multipathway process, with no single pathway representing more than 50% of the reactive current and all pathways representing at least 10%. We use the mutant simulations to show how the contributions of specific pathways can be rationally manipulated. Predicting the net effects of mutations is more challenging because the kinetics depend on all of the pathways, demanding quantitatively accurate simulations and experiments.

Abstract
OBJECTIVE The main aim of this study was to evaluate a combined fasting blood glucose based dosage self-titration setting and decision supported telephone coaching intervention on glycemic control and diabetes self-management skills, compared to the conventional care. METHODS A 12-week, single-blinded, randomized controlled trial was conducted on adults with type 2 diabetes (T2DM) primarily treated with basal insulin. After randomization, the intervention group (IG, n = 426) received a basal insulin self-titration decision support intervention administered by the Diabetes Specialty Nurses while the control group (CG, n = 423) received conventional care for 12 weeks, both included five telephone interviews. The primary efficacy endpoint was the effect of intervention on glycemic control, measured as the change in glycated hemoglobin (HbA1c) from baseline to Week 12 (after intervention) compared to the control group. Other endpoints included comparisons of the effects of intervention on fasting plasma glucose (FPG), postprandial plasma glucose (PPG), body weight, Michigan diabetes knowledge test (MDKT), diabetes empowerment scale-short Form (DES-DSF), and summary of diabetes self-care activities (SDSCA). Changes in the primary and secondary outcomes were compared using the t-test for continuous variables with a normal distribution and χ 2-test for categorical variables. RESULTS The IG showed more improvements on mean HbA1c, compared to the CG (-2.8% vs -1.8%), so did the FPG, PPG, MDKT, DES-DSF and SDSCA (all P<0.01) after the 12-week follow up. Though the final mean insulin dose in the IG was higher than the CG at the end of the study (0.32 U/kg vs 0.28 U/kg), the changes of body weight were similar between the two groups (0.46kg vs 0.40kg, P=0.246), and the proportion of patients with hypoglycemia events during the whole trial were similar (20.65% vs 17.73%, P=0.279). CONCLUSION Decision supporting of basal insulin glargine self-titration assisted by Diabetes Specialty Nurses is effective and safe in patients with T2DM. Decision supported telephone coaching intervention offers ongoing encouragement, guidance, and determination of relevant sources of decisional conflict, facilitating adjusting the insulin dose.
