Effectiveness and safety of insulin glargine 300 U/mL in insulin-naïve individuals according to diabetes duration: Results from the REALI European pooled data analysis.

To evaluate the effectiveness and safety of insulin glargine 300 U/mL (Gla-300) initiation according to diabetes duration (DD). We analysed patient-level data from 2381 insulin-naïve individuals with type 2 diabetes (T2D), of whom 2349 (98.7%) were treated with Gla-300 for 24 weeks. Of the 2381 participants, 1048 (44.0%) had a DD of less than 8 years and 1333 (56.0%) had a DD of 8 years or longer. We further analysed the subgroups of participants having a DD of less than 4 years (N = 450), 4-8 years (N = 598), 8-12 years (N = 627) and 12 years or longer (N = 706). Mean ± standard deviation age was 60.2 ± 9.0 years in participants with a DD less than 8 years and 64.2 ± 8.8 years in those with a DD of 8 years or longer. At 24 weeks of Gla-300 therapy, HbA1c improved with a least-squares (LS) mean change from baseline of -1.88% (95% confidence interval [CI], -1.95 to -1.80) and -1.71% (95% CI, -1.77 to -1.65), respectively, resulting in a LS mean difference between groups of 0.17% (95% CI, 0.07 to 0.26; P = .0005). In the subgroup analysis, LS mean HbA1c reduction from baseline to week 24 was highest in participants with a DD of less than 4 years and lowest in participants with a DD of 12 years or longer. Overall, incidences of symptomatic and severe hypoglycaemia were low, irrespective of DD, without body weight changes. Gla-300 was effective and safe in insulin-naïve individuals with T2D, regardless of DD. Improvement in HbA1c was greater when Gla-300 was initiated in participants with a DD of less than 4 years, although the difference between the groups was modest.

7363 Comparing the Effectiveness of Various Insulin in Insulin Naive Type 2 Diabetes Mellitus Patients: A Study from Central India

Abstract Disclosure: K. Dash: None. S. Verma: None. U. Ayyagari: None. N. Kumari: None. A. Gwal: None. Introduction: Insulin is the cornerstone of treatment of type 2 diabetes mellitus (T2DM) and is the most efficacious treatment option. The evaluation of efficacy and safety of insulin therapy in real world setting is desirable as numerous options are currently available. This study aimed to compare the efficacy and safety of four different insulins in patients with T2DM. Methods: We conducted a retrospective observational study at our tertiary care hospital using medical records of patients with glycated hemoglobin (HbA1c) >8.5% who were not controlled on oral antidiabetic (OAD) medication and received add-on insulin treatment (Glargine U300, Lispro Biphasic 25/75, Glargine U100, IdegAsp). Glycemic control and incidence of hypoglycemia were analyzed from baseline to 6 months. Results: 101 patients were included. Mean age 56.4 years. 61.4% men. Mean duration of T2DM 13.3 years. 23 (22.8%), 27 (26.7%), 27 (26.7%), and 24 (23.8%) patients received Glargine U300, Lispro Biphasic 25/75, Glargine U-100, IdegAsp insulin respectively. At baseline, the mean (SD) HbA1c were 11.93% (1.85), 10.61% (1.55), 10.65% (1.59), and 10.58% (1.89) in patients receiving Glargine U300, Lispro Biphasic 25/75, Glargine U100, and IdegAsp, respectively. HbA1c, fasting plasma glucose (FPG) & post-prandial plasma glucose (PPG) improved significantly from baseline to 6 months across all four treatment groups (p<0.001). Glargine U300 showed a significantly greater mean reduction in HbA1c by 4.57% compared to Lispro Biphasic 25/75 (3.39%; p=0.032), Glargine U100 (2.88%; p=0.004), and IdegAsp (2.38%; p<0.001). The mean reduction in FPG, PPG, total cholesterol and triglycerides were comparable across all four treatment groups. The mean insulin doses (SD) were 15.48 (5.65) U, 23.83 (9.49) U, 20.44 (8.76) U, and 34.17 (14.57) U at baseline and 18.89 (5.39) U, 35.52 (10.37) U, 26.07 (8.92) U, and 43.58 (15.76) at 6 months, respectively. The doses of all insulins were titrated to fasting, post-meal, or pre-dinner SMBG readings as appropriate. There were no significant changes observed in the mean body weight and insulin dose in all four subgroups. The incidence of hypoglycemia (<70 mg/dL and <54 mg/dL) was numerically lower in Glargine U300 (3 and 1) group, than in Lispro Biphasic 25/75 (8 and 5), Glargine U100 (3 and 2), and IdegAsp (7 and 3) groups. As expected, biphasic insulin had a higher numerical incidence of hypoglycemia. Conclusion: All insulins demonstrated significant improvements in glycemic parameters over the study period. However, Glargine U300 demonstrated a significantly higher reduction in HbA1c with minimal hypoglycemia events compared to other insulins and can be considered in OAD uncontrolled patients. Our results should be interpreted with caution as the study was retrospective and had a small sample size. Presentation: 6/3/2024

6527 Genetic variants may influence the glycemic response to sodium-glucose cotransporter-2 inhibitors in the Mass General Brigham Biobank

Abstract Disclosure: J.H. Li: None. A. Barry: None. A. Huerta-Chagoya: None. L. Szczerbinski: None. J.M. Mercader: None. J.C. Florez: Consulting Fee; Self; AstraZeneca. Grant Recipient; Self; Novo Nordisk. Speaker; Self; Novo Nordisk, Merck. A. Leong: None. Background: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) are increasingly prescribed for the treatment of type 2 diabetes, but there is interindividual variability in glycemic response. We investigated whether two genetic variants, rs33954001, a missense variant (p.His615Gln) in SLC5A1 encoding SGLT1, and rs8050500 near SLC5A2 encoding SGLT2, previously associated with glycemic traits in genome-wide association studies, had any influence on short-term glycated hemoglobin (HbA1c) lowering in patients on SGLT2i treatment. Methods: We identified 1,961 ancestrally diverse, genotyped individuals with documented exposure to a SGLT2i in the Mass General Brigham Biobank, a hospital-based biobank linked with patient medical records. Of these, 736 individuals had a baseline HbA1c ≥ 6% within 6 months of the index appearance of an SGLT2i and a follow-up HbA1c measured 6-12 months after. Genotyping was performed on the Illumina Multi-Ethnic Genotyping Array and the Illumina Global Screening Array. Variants were imputed with the TOPMed reference panel. Using linear regression models, we evaluated the additive effect of the genetic variants on HbA1c reduction, defined as baseline HbA1c minus follow-up HbA1c, adjusted for age, sex, 10 genetic ancestry principal components to account for population stratification, the number of concomitant glucose-lowering drug classes, and three covariates accounting for potential genotyping batch effects. To determine whether genetic effects varied by pretreatment glycemic control, we tested for a genotype × baseline HbA1c interaction and performed stratified analysis by baseline HbA1c (≥ 8% vs. < 8%). Results: The mean age of participants was 63.7 years and 41% were female. The baseline HbA1c was 8.0 ± 1.9%. The mean HbA1c reduction was 0.6% over a mean follow-up time of 8.7 ± 1.6 months. None of the variants were associated with HbA1c reduction (p > 0.05) in the whole dataset. However, in stratified analyses, among those with baseline HbA1c ≥ 8% (n = 382), we observed that carriers of the G allele at rs33954001 had a 0.5% greater HbA1c reduction (p = 0.048) compared to those with CC genotype. Further adjustment for baseline renal function did not modify results. In the Genotype-Tissue Expression (GTEx) portal, the G allele was associated with higher SLC5A1 expression in nerve (p = 1 × 10-8), esophageal mucosa (p = 4 × 10-5) and stomach (p = 9 × 10-5), but not kidney. In the Translational human pancreatic Islet Genotype tissue-Expression Resource (TIGER), the G allele was associated with SLC5A1 expression in pancreatic islets (p = 2 × 10-6). Conclusion: Genetic variation in SLC5A1 may partly explain heterogeneity in SGLT2i treatment effects among people with sub-optimally controlled diabetes, possibly due to differences in SLC5A1 tissue-specific expression. These findings require validation in large hospital-based biobanks or dedicated clinical trials. Presentation: 6/2/2024

7792 Efficacy of Retatrutide for Weight Reduction and Its Cardiometabolic Effects Among Adults: A Systematic Review and Meta-Analysis

Abstract Disclosure: D.C. Lopez: None. J.T. Pajimna: None. M.D. Milan: None. G.V. Jasul: None. G. Orpilla: None. I. Zapanta: None. B. Serquiña: None. G. Dychiao: None. Background: Obesity remains to be a global health challenge and it is associated with several complications such as diabetes, cardiovascular disease, fatty liver disease, and reduced life expectancy. Although lifestyle modifications are the mainstay for weight management, long term maintenance of weight loss can be a challenge for many affected adults. There have been proven safe and effective pharmacologic interventions but these remain limited to date. One of the novel anti-obesity drugs, retatrutide, is a single peptide with agonist activity at the GLP-1, glucose-dependent insulinotropic polypeptide (GIP), and glucagon receptors. The aim of this systematic review and meta-analysis is to evaluate the effectiveness of this triple-hormone receptor agonist, Retatrutide, in weight reduction and assess its cardiometabolic effects in adults. Methodology: An extensive electronic database search was done to identify studies published from inception until December 2023. All randomized controlled trials (RCT) that evaluated the use of retatrutide for adult patients were included. The Cochrane Risk of Bias 2.0 tool was used to assess the risk of bias of each study. Meta-analysis was conducted to determine weight reduction and glycemic control using random effects model which was reported at 95% confidence interval. Statistical heterogeneity was assessed using I2 statistics and random effects analysis and sensitivity analysis were done to control for the heterogeneity. Results: A total of 3 eligible RCTs were included in the study, all of which had risk of bias ranging from low to unclear. Of these articles, in 2 RCTs involving 353 participants with type 2 diabetes mellitus, retatrutide showed significant weight reduction by 11.89kg as compared to placebo (MD -11.89; 95% CI -13.53 to -10.25) and decreased glycosylated hemoglobin (HbA1C) by 1.64% as compared to placebo (MD: -1.64%, 95% CI [-2.38, -0.89]). Using direct comparison, retatrutide 12mg reduced body weight by 11.83kg as compared to dulaglutide 1.5mg with significant difference (MD -11.83; 95% CI -18.50 to -5.16), and retatrutide showed slight decrease in HbA1C by 0.61% as compared to dulaglutide (MD -0.66; 95% CI -0.66 to -0.56). In another 1 RCT involving 338 non-diabetic adult patients with obesity, retatrutide decreased least-squares mean percentage in body weight by 24.2% and 83% of participants who received retatrutide achieved weight reduction of 15% or more at 48 weeks. Conclusion: The use of retatrutide may result in substantial reductions in mean body weight and HbA1C as compared to controls in adult patients, with low to moderate certainty of evidence. In addition, retatrutide showed marked decrease in body weight but with modest glucose lowering effect when compared to a single GLP1 agonist drug. Presentation: 6/3/2024

The Endogenous Inhibitor of CETP, apoC1, Remains Ineffective In Vivo after Correction of Hyperglycemia in People with Type 1 Diabetes.

ApolipoproteinC1 (apoC1) is the main physiological inhibitor of the cholesterol ester transfer protein (CETP). Increased CETP activity is associated with macrovascular complications in patients with type 1 diabetes (T1D). ApoC1 has lost its ability to inhibit CETP in patients with T1D, and in vitro glycation of apoC1 increases CETP activity, suggesting that hyperglycemia could be a factor implicated in the loss of the inhibitory effect of apoC1 on CETP. Thus, we aimed to see whether improvement of glycemic control might restore apoC1 inhibitory effect on CETP. We studied 98 patients with T1D and HbA1c > 9% at baseline and 3 months after improvement of glycemic control by a medical intervention (insulin introduction or changes in multi-injection therapy or pump therapy introduction/therapeutic education for all patients). CETP activity was assessed by a radioactive method and plasma apoC1 levels were measured by ELISA. The different isoforms of apoC1 were determined by mass spectrometry. CETP activity was not significantly modified after improvement of glycemic control, despite a significant reduction in mean HbA1c (8.7 ± 1.7 vs. 10.8 ± 2, p < 0.0001). No association between plasma apoC1 and CETP activity was observed in patients with T1D at baseline, nor at 3 months, even in the subgroup of patients with optimal control (3-month HbA1c < 7%). We did not find any glycated form of apoC1 using mass spectrometry in people with T1D. Hyperglycemia in vivo does not seem to be a major factor implicated in the loss of apoC1 ability to inhibit CETP activity observed in T1D. Other factors, such as qualitative abnormalities of lipoproteins, could be involved. Our data emphasize the fact that hyperglycemia is not the only factor involved in lipid abnormalities and macrovascular complications in T1D. Clinical trial reg. no. NCT02816099 ClinicalTrials.gov.

Effectiveness and safety of once-weekly semaglutide: findings from the SEMACOL-REAL retrospective multicentric observational study in Colombia.

Diabetes stands as one of the leading causes of death worldwide. Glucagon-like peptide-1 receptor agonists rank among the most effective medications for lowering blood glucose and body weight, as well as reducing cardiovascular risk in individuals with diabetes. Observational studies complement experimental evidence in new settings, different populations, and real-world healthcare practices. A multicentric observational study of adults with type 2 diabetes treated with once-weekly subcutaneous semaglutide in four health centers in Colombia was conducted. The protocol for the present study was not pre-registered. Data from 186 patients were included. Most patients were women (57%) with a mean age of 62.8 ± 12.1 years. One year of once-weekly semaglutide usage was associated with a mean reduction in HbA1C of -1.47% (95% CI -1.76, -1.17), weight loss of -4.23 kg (95% CI -5.34, -3.12), and albumin/creatinine ratio of -18.6 mg/g (95% CI -60.2, -5.9). Approximately half the treated patients achieved a level of HbA1c ≤7% by the end of follow-up. Adverse events were rare and consistent with clinical trial safety profiles. In Colombia, administering semaglutide subcutaneously once a week over a 1-year period led to an average weight loss of 4.2kg and a decrease of 1.4% in HbA1c.

929-P: A Study to Evaluate Clinical and Metabolic Profile of Type 2 Diabetes Patients Receiving SGLT2 Inhibitors

Aim: The aim of the study was to determine the efficacy of SGLT2i and its impact on metabolic profile of type 2 diabetes (T2DM) patients with reference to serum glucagon and blood ketones. Methodology: The study was conducted in T2DM patients with inadequate glycemic control on a background therapy of either metformin and sulphonylurea (Group A) or metformin and DPP4 inhibitor(Group B) Blood samples were taken for estimation of fasting plasma glucose (FPG), post prandial plasma glucose (PPPG), HbA1c, beta-hydroxybutyrate (β-HB) and glucagon levels. Empagliflozin 10mg, was added to the existing anti-diabetic medication. The metabolic parameters were reassessed after 12 weeks. Results: At the end of 12 weeks glucagon levels increased significantly (28.8 ± 28.74 at baseline vs 108 ± 74 pg/ml; p&amp;lt;0.001). A significant increase in β-HB levels was also observed (0.1 ± 0.07 mmol/L at baseline versus 0.12 ± 0.07 mmol/L (p=0.03). FPG, PPPG and HbA1c decreased significantly by 30.33mg%, 53.16mg% and 1.05% respectively(p&amp;lt;0.01) In group A, FPG and PPPG decreased by 34.43 mg/dl and 51.71mg/dl respectively (p&amp;lt;0.001) with a mean HbA1c reduction of 1.09% (p&amp;lt;0.001) Serum glucagon and β-HB levels increased significantly [82.63 pg/ml (p&amp;lt;0.001) and 0.04 mmol/L (p&amp;lt;0.01) respectively]. In group B, there was decrease in FPG (mean difference 23.6mg %; p=0.003) and PPPG (mean difference 55.5mg%; p&amp;lt;0.001) at 12 weeks. HbA1c reduction of 0.99% was observed. (p=0.003) There was a significant increase in glucagon levels (mean difference +73.52 pg/ml; p&amp;lt;0.001). Conclusion: Addition of Empagliflozin to T2DM patients with inadequate glycemic control on either metformin and sulphonylurea or metformin and DPP4 inhibitors significantly improved efficacy. Plasma glucagon and β-HB levels increased with chronic empagliflozin treatment suggesting a change in substrate utilization towards fat. Disclosure S. Kandula: None. M.A. Meshram: None. A.C.

Efficacy and Safety of DPP-4 Inhibitors and Metformin Combinations in Type 2 Diabetes: A Systematic Literature Review and Network Meta-Analysis.

Several oral antidiabetic regimens are available for treating type 2 diabetes mellitus (T2DM), dipeptidyl peptidase-4 inhibitors (DPP4i) being one of them. We conducted a network meta-analysis (NMA) comparing DPP4i plus metformin (Met) combination with other Met-based oral antidiabetic drug (OAD) combinations used in treating patients with T2DM. We searched PubMed and Embase from inception until 19th April, 2022 for phase II and phase III trials in patients with T2DM on Met-based traditional OADs. The primary outcome was assessed by change in glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), and 2-hour post-prandial blood glucose (2h-PPG). The secondary safety outcomes assessed were hypoglycemic events, serious adverse events (SAEs), cardiovascular (CV) events, and gastrointestinal (GI) events. Sixty-two trials were included in the analysis. The combination of DPP4i + Met revealed a comparable mean reduction in HbA1c levels to the glinides (Gli) + Met combination (mean difference [MD]: -0.03%, 95% CI: 0.69, -0.65), although the difference was not statistically significant. The mean HbA1c reduction with DPP4i + Met was greater than with sulfonylureas (SU) + Met (MD: -0.05, 95% CI: -0.29, 0.39), thiazolidinedione (TZD) + Met (MD: -0.69, 95% CI: -1.39, -0.02), and SU + TZD (MD: 0.21; 95% CI: -1.30, 1.71), with no statistical significance. DPP4i + Met demonstrated a non-significant lower incidence of CV events in comparison to TZD + Met (RR: 1.01, 95% CI: 0.46, 2.45) and SU + Met (RR: 1.06, 95% CI: 0.61, 2.06). DPP4i in combination with Met was efficacious and had a well-tolerated safety profile compared with other traditional OADs. This combination can be considered as a suitable treatment option for patients with T2DM.

Effect of add on therapy of SGLT 2 inhibitors on glycaemic parameters

Background: Glycaemic control in type 2 diabetes mellitus can be difficult to attain, even with a combination of multiple oral agents as well as Insulin. SGLT2 inhibitors are potential novel agents inhibits the sodium glucose co transporters operated in the kidney tubules independent of the action on insulin resistance or secretion. This study aimed to evaluate the effect on the mean reduction of HbA1c levels. Also, to evaluate the effect of gliflozins on the mean reduction of FBS and PPBS values at the end of 3rd and 6th months and to find out the ADR profile over 6 months. Methods: Prospective observational study conducted on the patients with type 2 diabetes mellitus with HbA1c &gt;7% not controlled on metformin in the outpatient over a period of 15 months. An initial visit and thereafter follow up visits at 3rd and 6th month. HbA1c, FBS and PPBS was noted. ADR profile was also noted. Results: Significant mean reduction in the glycemic parameters among 90% study population with 0.5% reduction in mean HbA1c from the baseline. Also, the reduction in FBS and PPBS were statistically significant by 3rd month of the treatment. Incidence of genital itching was more compared with conventional drugs. Hypotension and polydipsia were rare. Conclusions: SGLT 2 inhibitors are found to be a promising new category of antidiabetic medications with better control of FBS, PPBS and HbA1c.

Evaluating the Impact of Intensifying Treatment from Human to Analogue Insulin on Glycaemic Control and Insulin Expenditure in Patients with Type 2 Diabetes: A Retrospective Cohort Study.

Achieving good glycaemic control is essential to reducing the risk of diabetes complications. Insulin is the most effective therapy for achieving good glycaemic control; however, it is associated with a higher risk of hypoglycaemia, especially with human insulin. This study aimed to evaluate the efficacy of intensification from human to analogue insulin and its added cost. This retrospective study was conducted at the Hospital Universiti Sains Malaysia (HUSM). Patients with type 2 diabetes mellitus (T2DM) who underwent intensification for at least 3 months from human to analogue insulin were included in this study. The patients' medical records, haemoglobin A1c (Hba1c) and fasting blood sugar (FBS) were retrieved. The total cost pre- and post-intensification of insulin was obtained from the pharmacy database. Differences in HbA1c, FBS and total insulin cost pre- and post-intensification were analysed. A total of 163 patients with T2DM who had intensification from human to analogue insulin were included in this study. HbA1c and FBS levels were significantly lower in analogue insulin. However, the differences were not clinically significant, as the mean reduction in HbA1c was less than 0.5%. Meanwhile, the total costs of analogue insulin for 3 months were higher. There were no clinically significant improvements in patients' HbA1c and FBS after the intensification of insulin, despite the extra costs spent. Hence, it is vital to choose the right group of patients to receive an insulin analogue to maximise its benefit but at the most optimal cost.

The use of FreeStyle libre improves glycaemic control along with reducing diabetes burden and hospital admissions in a socially deprived Northwest English population.

This retrospective study aimed to use mixed (qualitative and quantitative) methods to evaluate the role of FSL in reducing hospital admissions due to all causes, HbA1c, and reported hypoglycaemic episodes in people with diabetes living in a socially deprived region of Northwest England. Data were collected retrospectively from previous consultations, which coincided with the 6th -week, 6th -month and annual review including blood tests, hospital admissions due to any cause and reported hypoglycaemia. Also, FSL assessment and satisfaction semi-structured questionnaire was done to assess the impact of FSL on diabetes management and quality of life. Mixed-effects models were used to assess glycaemic control and reductions in hospital admissions and reported hypoglycaemic episodes. Just 127 patients met the inclusion criteria. A multivariate linear mixed model method that analyses HbA1c data longitudinally revealed mean differences (mmol/mol) between baseline and post-FSL measurements, estimated by restricted maximum likelihood method (REML) of 9.64 (six weeks), 7.68 (six months) and 7.58 (annual review); all with a corresponding p-value of < 0.0001. For DKA patients, the bootstrap method revealed a significant reduction in mean HbA1c of 25.5, 95% confidence interval (CI) [8.8, 42.6] mmol/mol. It is demonstrated that FSL use for one year resulted in 59% reduction in hospital admissions and 46% reduction in reported hypoglycaemic episodes. The use of FSL resulted in statistically significant reductions in hospital admissions, HbA1c and reported hypoglycaemic episodes among diabetics in a socially deprived Northwest region of England. These outcomes show a direct association with a higher questionnaire score. The online version contains supplementary material available at 10.1007/s40200-024-01424-4.

Real-World Effectiveness of the Gla-300 + Cap + App Program in Adult Users Living with Type2 Diabetes in Taiwan.

Health2Sync (H2S) is a digital health technology platform that provides coaching and titration support to patients with diabetes. The Mallya cap converts a conventional insulin pen into a smart connected device that can automatically synchronize dose values and associated timestamps (upon injection) to the H2S platform. This single-arm real-world study evaluated the effectiveness of insulin glargine 300U/mL (Gla-300) combined with H2S and Mallya cap (Gla-300 + Cap + App program) on clinical outcomes among users with type 2 diabetes (T2D) in Taiwan. Adults (aged ≥ 20years) with T2D who were registered H2S users and initiated Mallya cap for a new/existing Gla-300 regimen (identification period May1, 2021-May31, 2022) were included in this retrospective cohort study. Follow-up data from H2S were collected for 90days. Glycated hemoglobin (HbA1c) change (baseline to follow-up) and HbA1c goal attainment were primary outcomes. Hypoglycemia incidence and usage metrics of Mallya cap were secondary outcomes. Of 83 participants, 38.6% were new Gla-300 users. HbA1c was reduced in both new (- 2.4 [2.7] %, - 26.2 [29.5] mmol/mol) and previous Gla-300 users (- 0.5 [1.6] %, - 5.5 [17.5] mmol/mol). Reduction in HbA1c was significant (p < 0.05) in both groups. At follow-up, 43.4% of users had a reduction of > 0.5%. Mean HbA1c reductions increased numerically with higher baseline HbA1c and with longer duration of Mallya cap usage. Use of digital technology within a connected ecosystem such as Gla-300 + Cap + App program could help people with type2 diabetes to improve their glycemic condition.

Combination of retagliptin and henagliflozin as add-on therapy to metformin in patients with type 2 diabetes inadequately controlled with metformin: A multicentre, randomized, double-blind, active-controlled, phase 3 trial.

This study assessed the efficacy and safety of co-administering retagliptin and henagliflozin versus individual agents at corresponding doses in patients with type 2 diabetes mellitus who were inadequately controlled with metformin. This multicentre, phase 3 trial consisted of a 24-week, randomized, double-blind, active-controlled period. Patients with glycated haemoglobin (HbA1c) levels between 7.5% and 10.5% were randomized to receive once-daily retagliptin 100 mg (R100; n = 155), henagliflozin 5 mg (H5; n = 156), henagliflozin 10 mg (H10; n = 156), co-administered R100/H5 (n = 155), or R100/H10 (n = 156). The primary endpoint was the change in HbA1c from baseline to week 24. Based on the primary estimand, the least squares mean reductions in HbA1c at week 24 were significantly greater in the R100/H5 (-1.51%) and R100/H10 (-1.54%) groups compared with those receiving the corresponding doses of individual agents (-0.98% for R100, -0.86% for H5 and -0.95% for H10, respectively; p < .0001 for all pairwise comparisons). Achievement of HbA1c <7.0% at week 24 was observed in 27.1% of patients in the R100 group, 21.2% in the H5 group, 24.4% in the H10 group, 57.4% in the R100/H5 group and 56.4% in the R100/H10 group. Reductions in fasting plasma glucose and 2-h postprandial glucose were also more pronounced in the co-administration groups compared with the individual agents at corresponding doses. Decreases in body weight and systolic blood pressure were greater in the groups containing henagliflozin than in the R100 group. The incidence rates of adverse events were similar across all treatment groups, with no reported episodes of severe hypoglycaemia. For patients with type 2 diabetes mellitus inadequately controlled by metformin monotherapy, the co-administration of retagliptin and henagliflozin yielded more effective glycaemic control through 24 weeks compared with the individual agents at their corresponding doses.

Real-world glycated haemoglobin changes among type 2 diabetes mellitus patients treated with a maintenance dose of 7 mg or 14 mg of oral semaglutide.

To describe the change in glycated haemoglobin (HbA1c) among patients with type 2 diabetes following treatment with a 7 or 14 mg maintenance dose of oral semaglutide. This retrospective, claims-based study included adult patients with type 2 diabetes with a pre-index HbA1c of ≥7%, initiating treatment with oral semaglutide between 1 November 2019 and 30 June 2020; the patients had continuous health plan enrolment for ≥12 months before (pre-index) and ≥6 months following (post-index) the date of the first oral semaglutide claim (index). Patients were required to have a maintenance dose of 7 or 14 mg. Pre-index demographic and clinical characteristics were captured, as were doses at initiation and prescriber specialty. The change in HbA1c between the latest post-index and pre-index HbA1c measurements was calculated among all patients and among those with ≥90 days of continuous treatment (persistent patients). This study included 520 patients, most of whom had a complex medical history, experienced a range of comorbidities and received an average of 11.5 different classes of medications during the pre-index period. The mean HbA1c reduction during the 6-month post-initiation period was 1.2% (p < .001) for all patients and 1.4% (p < .001) for persistent patients. In this real-world study, patients with a pre-index HbA1c ≥7% who initiated treatment with oral semaglutide with a 7 or 14 mg maintenance dose had significantly lower HbA1c levels following treatment.

Comparative Study on Efficacy of Empagliflozin Versus Sitagliptin, as an Add-on Therapy to Metformin in Type 2 Diabetic Patients

ABSTRACT Introduction: More than 28.7 million individuals throughout the globe suffer from diabetes mellitus, with an estimated 11 percent of the population living with the condition in India. Changes in lifestyle and a variety of treatment plans are used in management. Metformin is a key drug for glycemic control, both when used alone and in combination. Our research compares the effectiveness of glycemic control achieved by empagliflozin plus sitagliptin. Methods: This study took place from November 2022 to April 2023 at the tertiary care hospital. The study did not begin until the ethical review was completed. There were two groups of patients, A and B. Everyone received a daily dose of Metformin 1,000 milligrams. Sitagliptin (50 mg twice daily) was administered to individuals in Group A, whereas Empagliflozin (10 mg once daily) was given to those in Group B. After three months of therapy, HbA1c was used to compare the two groups’ levels of glycemic control to those at the start of treatment. To do this, we employed a proforma. Version 25 of the Statistical Package for the Social Sciences (SPSS Inc., Chicago, USA) was used for the analysis. Results: The average age of the 300 patients that participated in the trial was 42.33. There were 57.67% men and 42.33% females. “The mean reduction in HbA1c from baseline in Group A was −0.65 ± 0.11% and in Group B was −1.34 ± 0.13% with statistically significant P-value (P-value = 0.000).” Conclusion: The combination of Empagliflozin and Metformin is superior to that of Sitagliptin and Metformin for the maintenance of glycemic control.

Effectiveness of peer-led intervention in control of non-communicable diseases in rural areas of Khordha district: study protocol for a cluster randomized controlled trial

BackgroundThe main contributors to death and disability from chronic illnesses in developing nations are elevated blood pressure (hypertension), blood sugar (diabetes mellitus), and blood cholesterol (dyslipidaemia). Even though there are affordable treatments, the treatment gap for these conditions is still significant. Few pilot studies from industrialized nations discuss the value of peer-led interventions for achieving community-level management of blood pressure and blood sugar. This study aims to evaluate the effectiveness of peer-led intervention compared to standard care in achieving control of selected non-communicable diseases (NCDs) in Indian context at 1 year of intervention among people of 30–60 years with hypertension and/or diabetes mellitus and/or dyslipidaemia.MethodsA cluster-randomized controlled trial will be conducted in villages of two rural blocks of the Khordha district of Odisha from August 2023 to December 2024. A total of 720 eligible participants (360 in the intervention group and 360 in the control group) will be recruited and randomized into two study arms. The participants in the intervention arm will receive a peer-led intervention model for 6 months in addition to standard care. The sessions will be based on the six domains of NCDs — self-care, follow-up care, medication, physical activity, diet, limiting substance use, mental health and co-morbidities. The mean reduction in blood pressure, HbA1C, and blood cholesterol in the intervention arm compared to the standard care arm will be the main outcome.DiscussionThe increasing burden of NCDs demands for newer strategies for management. Peer-led interventions have proven to be useful at the international level. Incorporating it in India will have remarkable results in controlling NCDs.Trial registrationClinical Trial Registry of India (CTRI) CTRI/2023/02/050022. Registered on 23 February 2023.

Treatment of Painful Diabetic Neuropathy with 10 kHz Spinal Cord Stimulation: Long-Term Improvements in Hemoglobin A1c, Weight, and Sleep Accompany Pain Relief for People with Type 2 Diabetes.

The recent SENZA-PDN study showed that high-frequency (10kHz) spinal cord stimulation (SCS) provided significant, durable pain relief for individuals with painful diabetic neuropathy (PDN), along with secondary benefits, including improved sleep quality and HRQoL. Given that metabolic factors and chronic neuropathic pain are related, we evaluated potential secondary effects of 10kHz SCS on hemoglobin A1c (HbA1c) and weight in SENZA-PDN participants with type 2 diabetes (T2D). This analysis included 144 participants with T2D and lower limb pain due to PDN who received 10kHz SCS during the SENZA-PDN study. Changes in HbA1c, weight, pain intensity, and sleep were evaluated over 24 months, with participants stratified according to preimplantation HbA1c (>7% and >8%) and body mass index (BMI; ≥30 and ≥35 kg/m2). At 24 months, participants with preimplantation HbA1c >7% and >8% achieved clinically meaningful and statistically significant mean reductions in HbA1c of 0.5% (P = 0.031) and 1.1% (P = 0.004), respectively. Additionally, we observed a significant mean weight loss of 3.1 kg (P = 0.003) across all study participants. In subgroups with BMI ≥30 and ≥35 kg/m2, weight reductions at 24 months were 4.1 kg (P = 0.001) and 5.4 kg (P = 0.005), respectively. These reductions were accompanied by a mean pain reduction of 79.8% and a mean decrease in pain interference with sleep of 65.2% at 24 months across all cohorts. This is the first study of SCS to demonstrate long-term, significant, and clinically meaningful reductions in HbA1c and weight in study participants with PDN and T2D, particularly among those with elevated preimplantation HbA1c and BMI. Although the mechanism for these improvements has yet to be established, the results suggest possible direct and indirect metabolic benefits with 10kHz SCS in addition to durable pain relief.

Dose–response effects on HbA1c and bodyweight reduction of survodutide, a dual glucagon/GLP-1 receptor agonist, compared with placebo and open-label semaglutide in people with type 2 diabetes: a randomised clinical trial

Aims/hypothesisThe aim of this study was to assess the dose–response effects of the subcutaneous glucagon receptor/glucagon-like peptide-1 receptor dual agonist survodutide (BI 456906) on HbA1c levels and bodyweight reduction.MethodsThis Phase II, multicentre, randomised, double-blind, parallel-group, placebo-controlled study, conducted in clinical research centres, assessed survodutide in participants aged 18–75 years with type 2 diabetes, an HbA1c level of 53–86 mmol/mol (7.0–10.0%) and a BMI of 25–50 kg/m2 on a background of metformin therapy. Participants were randomised via interactive response technology to receive survodutide (up to 0.3, 0.9, 1.8 or 2.7 mg once weekly [qw; dose group (DG) 1–4, respectively] or 1.2 or 1.8 mg twice weekly [DG 5 and 6, respectively]), placebo or semaglutide (up to 1.0 mg qw). Participants and all those involved in the trial conduct/analysis were blinded; the semaglutide arm was open-label. The primary endpoint was absolute change from baseline in HbA1c after 16 weeks’ treatment. The key secondary endpoint was relative change from baseline in bodyweight after 16 weeks’ treatment.ResultsA total of 413 participants were randomised (DG1, n=50; DG2, n=50; DG3, n=52; DG4, n=50; DG5, n=51; DG6, n=50; semaglutide, n=50; placebo, n=60). The full analysis set comprised 411 treated participants (DG6, n=49; placebo, n=59). Adjusted mean (95% CI) HbA1c decreased from baseline (mean ± SD 64.7±9.2 mmol/mol [8.07±0.84%] after 16 weeks’ treatment: DG1 (n=41), −9.92 mmol/mol (−12.27, −7.56; −0.91% [−1.12, −0.69]); DG2 (n=46), −15.95 mmol/mol (−18.27, −13.63; −1.46% [−1.67, −1.25]); DG3 (n=36), −18.72 mmol/mol (−21.15, −16.29; −1.71% [−1.94, −1.49]); DG4 (n=33), −17.01 mmol/mol (−19.59, −14.43; −1.56% [−1.79, −1.32]); DG5 (n=44), −17.84 mmol/mol (−20.18, −15.51; −1.63% [−1.85, −1.42]); DG6 (n=36), −18.38 mmol/mol (−20.90, −15.87; −1.68% [−1.91, −1.45]). The mean reduction in HbA1c was similar with low-dose survodutide (DG2: −15.95 mmol/mol [−1.46%]; n=46) and semaglutide (−16.07 mmol/mol [−1.47%]; n=45). Mean (95% CI) bodyweight decreased dose-dependently up to −8.7% (−10.1, −7.3; DG6, n=37); survodutide ≥1.8 mg qw produced greater bodyweight reductions than semaglutide (−5.3% [−6.6, −4.1]; n=45). Adverse events (AEs) were reported for 77.8% of survodutide-treated participants (mainly gastrointestinal), 52.5% receiving placebo and 52.0% receiving semaglutide.Conclusions/interpretationSurvodutide reduced HbA1c levels and bodyweight after 16 weeks’ treatment in participants with type 2 diabetes. Dose-related gastrointestinal AEs could be mitigated with slower dose escalations.Trial registrationClinicalTrials.gov NCT04153929 and EudraCT 2019-002390-60.FundingBoehringer Ingelheim Pharma GmbH & Co.

Real-world safety and effectiveness of dapagliflozin in people living with type 1 diabetes in Spain: The Dapa-ON multicenter retrospective study

ObjectiveTo assess real-world safety and effectiveness of dapagliflozin in people living with type 1 diabetes mellitus (T1DM). MethodsWe conducted a multicenter retrospective study in Spain including data from 250 people living with T1DM receiving dapagliflozin as add-on therapy to insulin (80.8 % on-label use). The number of diabetic ketoacidosis (DKA) events was calculated over a 12-month follow-up (primary outcome). Changes in body weight, HbA1c, total daily insulin dose, and continuous glucose monitoring (CGM) metrics from baseline (at dapagliflozin prescription) to 12 months were also evaluated. ResultsA total of five DKA events (2.4 % [95 % CI 0.3;4.5] were reported in patients with a 12-month follow-up, n = 207): two events related to insulin pump malfunction, two events related to concomitant illnesses, and one event related to insulin dose omission. DKA events were more frequent among insulin pump users than among participants on multiple daily injections (7.7 % versus 1.2 %). Four of the reported DKA events occurred within the first six months after initiation of dapagliflozin. No deaths or persistent sequelae due to DKA were reported. No severe hypoglycemia episodes were reported. Significant reductions in mean body weight (−3.3 kg), HbA1c (−0.6 %), and total daily insulin dose (−8.6 %), P < 0.001, were observed 12 months after dapagliflozin prescription. Significant improvements in TIR (+9.3 %), TAR (−7.2 %), TBR (−2.5 %), and coefficient of variation (−5.1 %), P < 0.001, were also observed in the subgroup of patients with available CGM data. Finally, an improvement in urinary albumin-to-creatinine ratio (UACR) was found among participants with UACR ≥ 30 mg/g at baseline (median decrease of 99 mg/g in UACR, P = 0.001). ConclusionThe use of dapagliflozin in people living with T1DM has an appropriate safety profile after careful selection of participants and implementation of strategies to reduce the risk of DKA (i.e., prescribed according to the recommendations of the European Medicines Agency), and also leads to clinical improvements in this population.

Real-world HbA1c changes and prescription characteristics among type 2 diabetes mellitus patients initiating treatment with once weekly semaglutide for diabetes

PurposeThe purpose of this study was to evaluate patient, prescriber, and dose characteristics and evaluate changes in glycated hemoglobin (HbA1c) for patients prescribed once weekly semaglutide for diabetes (OW sema T2D).MethodsThis study was a retrospective claims-based study using the Optum Research Database. The sample included adult patients who had at least one claim for OW sema T2D between Jan 1, 2018, and Dec 31, 2019, were continuously enrolled in the health plan and had a diagnosis of type 2 diabetes (T2DM) during the pre-index or post-index periods. Demographic and clinical characteristics of patients using OW sema T2D were collected, as were the dose and prescriber specialty and the change between pre-index and post-index HbA1c measures was calculated. Results were stratified by the latest pre-index HbA1c measurement (HbA1c greater than or equal to 9.0%, uncontrolled vs. HbA1c less than 9%, controlled). Statistical comparisons between HbA1c groups were conducted.ResultsMost patients, 76.3%, were prescribed a 0.25/0.50 mg dose of OW sema T2D. Patients had an overall decrease in HbA1c of 0.8% and patients with uncontrolled diabetes had a greater reduction in mean HbA1c compared to those with controlled diabetes (-2.1% vs. -0.3%, p < 0.001). Most patients had their index dose of OW sema T2D prescribed by endocrinologists (27.6%) primary care providers (24.6%) and internal medicine providers (21.6%).ConclusionsOW sema T2D is an effective real-world T2DM treatment. Future research should further investigate real-world use patterns of this medication.
