Comparation of fixed-ratio (IDegLira and iGlarLixi) versus free combination of basal insulin and glucagon-like peptide-1 receptor agonist for uncontrolled type 2 diabetes: A systematic review and network meta-analysis. J Evid Based Med 2024; 17:370-376. [PMID: 38858300 DOI: 10.1111/jebm.12620] [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: 12/27/2023] [Accepted: 05/31/2024] [Indexed: 06/12/2024]
Abstract
OBJECTIVE This study aimed to evaluate the safety and efficacy of the fixed-ratio combination (FRC) and free combination of basal insulin and glucagon-like peptide-1 receptor agonist (GLP-1RA) in patients with type 2 diabetes mellitus (T2DM). METHODS PubMed, Web of Science, Embase, The Cochrane Library, and four Chinese databases were searched for relevant studies from inception to April 13, 2023. Phase III clinical trials involving FRC or free combination in patients with uncontrolled T2DM were included. A network meta-analysis (NMA) was used to evaluate the effects of FRC and free combination. The Cochrane Collaboration's tool was used to evaluate the risk-of-bias. The primary outcomes were changes in hemoglobin A1c (HbA1c), body weight, and incident hypoglycemia. Secondary outcomes included changes in systolic blood pressure (SBP) and diastolic blood pressure (DBP). This study was registered with PROSPERO (CRD42023409585). RESULTS Forty-two trials with 23,619 patients were included in the NMA, and treatments were categorized as FRC, free combination and NOINSGLP (neither FRC nor free combination). The forest plots revealed comparable HbA1c control (mean difference (MD) = 0.07%, 95% confidence interval (CI): -0.17 to -0.30) between free combination and FRC. However, there were significant differences in the body weight (MD = -2.06 kg; 95% CI: -3.34 to -0.77), SBP (MD = -1.22 mmHg; 95% CI: -2.41 to -0.04), and DBP (MD = -1.09 mmHg; 95% CI: -1.94 to -0.24) between the two groups. CONCLUSIONS In patients with uncontrolled T2DM, the safety and efficacy of FRC and free combination therapy were comparable. The use of FRC is justifiable in patients requiring free combination.

Nutr Metab Cardiovasc Dis 2023; 33:2294-2305. [PMID: 37679243 DOI: 10.1016/j.numecd.2023.07.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 07/10/2023] [Accepted: 07/14/2023] [Indexed: 09/09/2023]
Abstract
BACKGROUND AND AIMS To assess intensification approaches with basal insulin (BI) following glucagon-like peptide-1 receptor agonist (GLP-1 RA) treatment in type 2 diabetes (T2D). METHODS AND RESULTS Real-world data were collected in electronic medical records by 32 Italian diabetes clinics between 2011 and 2021. Primary endpoint was the proportion of insulin-naïve T2D patients treated with GLP-1 RA who initiated (add-on or switch) BI. Secondary endpoints were: treatment approaches, mean time to BI start, effectiveness and safety. Among 7,962 eligible patients, BI was prescribed to 3,164 (39.7%; 95%CI 38.7; 40.8): 67.6% switched to BI (22.1% also starting 1-3 injections of short-acting insulin), 22.7% added BI while maintaining GLP-1 RA, and 9.7% switched to a fixed-ratio combination of GLP-1 RA and BI (FRC). Median time since the first GLP-1 RA to BI/FRC prescription was 27.4 (IQ range 11.8-53.5) months. In this study 60.3% of patients did not start BI/FRC, among whom 15.2% intensified GLP-1 RA therapy with other oral agents. Effectiveness and safety were documented in all intensification approaches with BI/FRC, but HbA1c level at intensification time of ≥9.0% and suboptimal BI titration suggested clinical inertia. Use of second generation BI and add-on to GLP-1 RA schemes increased over time and effectiveness improved. CONCLUSION Clinical inertia should be overcome using innovative insulin options. Timely combination therapy of BI and GLP-1 RA is a valuable choice.

Nomoto H. Fixed-ratio combinations of basal insulin and glucagon-like peptide-1 receptor agonists as a promising strategy for treating diabetes. World J Diabetes 2023; 14:188-197. [PMID: 37035222 PMCID: PMC10075027 DOI: 10.4239/wjd.v14.i3.188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 01/13/2023] [Accepted: 02/09/2023] [Indexed: 03/15/2023] Open
Abstract
The maintenance of appropriate glycemic control is important for the prevention of diabetic complications in people with type 2 diabetes (T2D). Numerous oral antidiabetic drugs are now clinically available, but in particular, the introduction of injection regimens using insulin and/or glucagon-like peptide-1 receptor agonist (GLP-1RA)s represents promising step-up options for oral antidiabetic drug treatment. The recently licensed fixed-ratio combination (FRC) products, which comprise basal insulin and a GLP-1RA, have potent anti-hyperglycemic effects and reduce the undesirable side-effects of each component, such as body weight gain, hypoglycemia, and gastrointestinal symptoms. Two FRCs-insulin degludec/Liraglutide and insulin glargine/Lixisenatide-are now clinically available and, to date, several phase II/III trials have been conducted in particular groups of subjects with T2D. However, their utility in real-world clinical settings is of interest for most clinicians. Recently reported real-world clinical trials of these two FRCs in various situations have demonstrated their efficacy regarding glycemic control and the quality of life of people with T2D. Their long-term safety and efficacy require confirmation, but a treatment strategy that includes an FRC may be compatible with the concept of “well-balanced” therapy in certain groups of patients with T2D who have inadequate glycemic control.

Abstract
AIM To compare effectiveness of dapagliflozin versus DPP-4 inhibitors on individualized HbA1c targets and extra-glycaemic endpoints among elderly patients with type 2 diabetes (T2D). METHODS This was a multicentre retrospective study on patients aged 70-80 years with HbA1c above individualized target and starting dapagliflozin or DPP-4 inhibitors in 2015-2017. The primary outcome was the proportion reaching individualized HbA1c targets. Confounding by indication was addressed by inverse probability of treatment weighting (IPTW), multivariable adjustment (MVA), or propensity score matching (PSM). RESULTS Patients initiating dapagliflozin (n = 445) differed from those initiating DPP-4i (n = 977) and balance between groups was achieved with IPTW or PSM. The median follow-up was 7.5 months and baseline HbA1c was 8.3%. A smaller proportion of patients initiating dapagliflozin attained individualized HbA1c target as compared to those initiating DPP-4 inhibitors (RR 0.73, p < 0.0001). IPTW, MVA, and PSM yielded similar results. Between-group difference in the primary outcome was observed among patients with lower eGFR or longer disease duration. Dapagliflozin allowed greater reductions in body weight and blood pressure than DPP-4 inhibitors. CONCLUSIONS Elderly patients with T2D initiating dapagliflozin had a lower probability of achieving individualized HbA1c targets than those initiating DPP-4 inhibitors but displayed better improvements in extra-glycaemic endpoints.

Real-world effectiveness of IDegLira compared with intensified conventional insulin therapy in adults with type 2 diabetes: a retrospective cohort study. BMC Endocr Disord 2022; 22:229. [PMID: 36104712 PMCID: PMC9476268 DOI: 10.1186/s12902-022-01139-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Accepted: 08/26/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND IDegLira is a fixed-ratio combination of insulin degludec and liraglutide with proven efficacy against simpler regimens and non-inferiority against basal-bolus insulin therapy. However, the evaluation of its real-world effectiveness is hindered by technical issues and requires further exploration. Thus we aimed to compare effectiveness of insulin degludec/liraglutide (IDegLira) versus intensified conventional insulin therapy (ICT) for type 2 diabetes in a real-world setting. METHODS This retrospective cohort study from an outpatient clinic in Hungary included people who initiated IDegLira due to inadequate glycaemic control (HbA1c > 7.0% [53.0 mmol/mol]) with oral and/or injectable antidiabetic drugs. Data were compared with a historical cohort who initiated ICT. Outcomes included HbA1c, body weight, and hypoglycaemia differences over 18 months of follow-up. RESULTS Data were included from 227 and 72 people who initiated IDegLira and ICT, respectively. Estimated mean difference (MD) in HbA1c at 18 months favoured IDegLira versus ICT (MD 0.60, 95% CI 0.88-0.32 [MD 6.6 mmol/mol, 95% CI 9.6-3.5]). More people reached target HbA1c ≤7.0% (53.0 mmol/mol) with IDegLira than ICT (odds ratio 3.36, 95% CI 1.52-7.42). IDegLira treatment was associated with weight loss compared with gain for ICT (MD 6.7 kg, 95% CI 5.0-8.5). The hazard ratio for hypoglycaemia comparing IDegLira with ICT was 0.18 (95% CI 0.08-0.49). CONCLUSIONS Treatment with IDegLira over 18 months resulted in greater HbA1c reductions, weight loss versus gain, and a lower rate of hypoglycaemia versus ICT in people with type 2 diabetes.

Abstract
AIMS Two fixed-ratio combinations (FRCs) of basal insulin and glucagon-like peptide-1 receptor agonist (GLP-1RA) are available for once-daily use in adults with type 2 diabetes. We aimed to review the clinical evidence for the efficacy and safety of changing treatment from a basal-bolus insulin (BBI) regimen or a premix insulin to these combination treatments (fixed-ratio or loose) and provide expert opinion on the practicalities of making such a change. METHODS Relevant clinical and trial evidence and general review articles were identified through a literature review of ProQuest (comprising BIOSIS Previews®, Current Contents® Search, Embase® and MEDLINE®) for articles published between 2009 and 2021. RESULTS We identified nine articles reporting the results of FRCs, and seven articles reporting results of loose combinations of basal insulin and GLP-1RAs, in people who transitioned treatment from BBI or premix regimens. In most trials, combination treatment led to improved or equivalent glycaemic control, and a reduction in body weight or BMI, versus the original regimens. Some trials reported a reduction in total insulin dose. A few trials reported reduced or unchanged hypoglycaemia rates, or increased patient satisfaction, with combination therapy where these endpoints were examined. We provide guidance on transitioning of treatment and the patient types most likely to benefit. CONCLUSIONS In people not achieving glycaemic control with BBI or premix insulin regimens, an FRC or loose combination of basal insulin and GLP-1RA may improve control, decrease the risk of body weight gain or hypoglycaemia and reduce the complexity of treatment.

Abstract
INTRODUCTION This study evaluates the efficacy and safety of the free up-titration of basal insulin and fixed-ratio combination (FRC) of basal insulin and glucagon-like peptide-1 receptor agonists (GLP-1RAs) in type 2 diabetes mellitus (T2DM) patients inadequately controlled with GLP-1RA. METHODS With the use of a systematic literature review of PubMed, Embase, Web of Science, and the Cochrane Library databases through July 2021, randomized controlled trials that compared the free up-titration or FRC with remaining on GLP-1RA in T2DM patients uncontrolled with GLP-1RA were included. A comparison of adding basal insulin to maintaining GLP-1RA and an indirect comparison between the two strategies were conducted on the change in HbA1c, fasting plasma glucose (FPG), target achievement [HbA1c < 7.0%], and the risk of confirmed hypoglycemia. The Cochrane Collaboration's tool was used to assess the risk of bias. RESULTS Two free up-titration and two FRC trials involving 1,612 participants, all lasting 26 weeks, were included. Both approaches significantly lowered HbA1c levels (weighted mean difference [WMD] -0.75%, 95% CI -0.97 to -0.53) but increased hypoglycemic risk [risk ratio (RR) 7.59, 95% CI 3.35-17.17] compared to the unchanged GLP-1RA. No significant differences were discovered between the two methods regarding the decrease in HbA1c (WMD 0.08%, 95% CI -1.07% to 1.23%), FPG (WMD -2.29 mg/dl, 95% CI -45.07 to 40.49 mg/dl), target achievement (RR 1.03, 95% CI 0.50-2.14), and hypoglycemic risk (RR 0.32, 95% CI 0.03-3.59). CONCLUSION In patients who failed to reach target HbA1c levels despite the GLP-1RA treatment, both strategies of adding basal insulin, free up-titration and FRC, are comparable options are comparable options.

Abstract
AIMS Metabolic dysfunction-associated fatty liver disease (MAFLD) is common in people with type 2 diabetes (T2D) and can progress to advanced fibrosis and cirrhosis. In this retrospective study, we explored the longitudinal changes in markers of hepatic steatosis and fibrosis during T2D treatment with glucagon-like peptide-1 receptor agonists (GLP-1RAs). METHODS We analysed observational data from six diabetes outpatient clinics. In the whole T2D population, we calculated the hepatic steatosis index (HSI), which we previously validated against liver ultrasonography, and the Fibrosis (Fib)-4 index. We then identified patients who initiated a GLP-1RA from 2010 to 2018 and for whom data were available to evaluate changes in both HSI and Fib-4 scores over 24 months. RESULTS From 83,116 outpatients with T2D, 41,302 (49.7%) had complete data for calculating HSI and Fib-4. Most of these T2D patients (∼70%) had MAFLD (defined as HSI>36), 9.7% of whom had advanced fibrosis based on Fib-4 thresholds. Patients with low compared to high risk of advanced fibrosis were 5-times more likely to be treated with GLP-1RA. In 535 patients who initiated a GLP-1RA, the prevalence of MAFLD based on HSI declined significantly at 6 and 24 months, but Fib-4 categories did not. HSI improved significantly only in patients receiving human-based but not exendin-based GLP-1RA, while patients concomitantly receiving metformin had less worsening in Fib-4 categories. CONCLUSIONS MAFLD is very common among outpatients with T2D (∼70%) and the estimated prevalence of advanced fibrosis was ∼10%. Treatment with GLP-1RAs significantly improved MAFLD, but not MAFLD-associated advanced fibrosis.

Abstract
Aim We aimed to compare cardiovascular outcomes of patients with type 2 diabetes (T2D) who initiated GLP-1 receptor agonists (GLP-1RA) or basal insulin (BI) under routine care. Methods We accessed the administrative claims database of the Veneto Region (Italy) to identify new users of GLP-1RA or BI in 2014–2018. Propensity score matching (PSM) was implemented to obtain two cohorts of patients with superimposable characteristics. The primary endpoint was the 3-point major adverse cardiovascular events (3P-MACE). Secondary endpoints included 3P-MACE components, hospitalization for heart failure, revascularizations, and adverse events. Results From a background population of 5,242,201 citizens, 330,193 were identified as having diabetes. PSM produced two very well matched cohorts of 4063 patients each, who initiated GLP-1RA or BI after an average of 2.5 other diabetes drug classes. Patients were 63-year-old and only 15% had a baseline history of cardiovascular disease. During a median follow-up of 24 months in the intention-to-treat analysis, 3P-MACE occurred less frequently in the GLP-1RA cohort (HR versus BI 0.59; 95% CI 0.50–0.71; p < 0.001). All secondary cardiovascular endpoints were also significantly in favor of GLP-1RA. Results were confirmed in the as-treated approach and in several stratified analyses. According to the E-value, confounding by unmeasured variables were unlikely to entirely explain between-group differences in cardiovascular outcomes. Conclusions Patients with T2D who initiated a GLP-1RA experienced far better cardiovascular outcomes than did matched patients who initiated a BI in the same healthcare system. These finding supports prioritization of GLP-1RA as the first injectable regimen for the management of T2D.

Delphi-Based Consensus on Treatment Intensification in Type 2 Diabetes Subjects Failing Basal Insulin Supported Oral Treatment: Focus on Basal Insulin + GLP-1 Receptor Agonist Combination Therapies. Diabetes Ther 2021; 12:781-800. [PMID: 33550569 PMCID: PMC7947045 DOI: 10.1007/s13300-021-01012-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Accepted: 01/23/2021] [Indexed: 01/27/2023] Open
Abstract
INTRODUCTION The aim of this study was to elaborate a consensus on treatment intensification strategies in patients with type 2 diabetes failing basal insulin supported oral therapy (BOT). The panel focused on glucagon-like peptide-1 receptor agonists (GLP-1RA) and basal insulin (BI) combinations. METHODS The authors developed a Delphi questionnaire organized into ten statements and 77 items that focused on: the definition of BOT and BOT failure, intensification strategies, fixed-dose combinations in general and the BI/GLP-1RA fixed combination. The survey was administered in two rounds to a panel of 80 Italian diabetes specialists, who rated their level of agreement with each item on a 5-point Likert scale. Consensus was predefined as > 66% of the panel agreeing/disagreeing on any given item. RESULTS Consensus was achieved for 71 of the 77 items. The panel agreed that the use of sulfonylureas in the BOT regimen is inappropriate. BOT failure was defined as individualized targets not being met for glycated hemoglobin, fasting plasma glucose and/or postprandial plasma glucose. There was agreement that postprandial hyperglycaemia and/or presence of nocturnal hypoglycaemia or weight gain define BOT failure. Addition of a GLP-1RA to BI therapy was considered to be the best option for BOT intensification. There was consensus for the use of BI/GLP-1RA fixed combinations as valuable options to increase compliance and safely improve glycaemic control. The panel agreed in considering the fixed-ratio combination insulin degludec/liraglutide (IDegLira) to be preferable to the fixed-ratio combination insulin glargine/lixisenatide (iGlarLixi) in the control of glycaemia, body weight and cardiovascular risk. CONCLUSION According to this Delphi consensus, the addition of a GLP-1RA may be the best option to intensify BOT. The BI/GLP-1RA fixed combinations may increase compliance and optimize the advantages of each of these molecules.

Abstract
AIMS We evaluated de-intensification of basal-bolus insulin (BBI) after initiation of a GLP-1 receptor agonist (GLP-1RA) under routine care. RESEARCH DESIGN AND METHODS This retrospective, multicenter study conducted at outpatient clinics in North-East Italy collected data on patients with T2D on BBI who initiated a GLP-1RA. Patients were divided according to whether they de-intensified BBI at the end of observation by stopping prandial insulin. RESULTS We included 425 patients with mean age of 61.3 years and 13 years of diabetes duration. Baseline HbA1c was 8.6% and BMI was 35.5 kg/m2. After 14 months. 58.6% of patients de-intensified BBI after initiating GLP-1RA: they were younger, had a shorter disease duration, lower HbA1c and insulin dose, and less frequent microangiopathy than those who continued BBI. A probability estimation based on these variables was validated in an independent cohort of 40 patients. Body weight improved in both groups, but HbA1c and fasting plasma glucose significantly declined only among patients who de-intensified BBI. Patients who de-intensified BBI and persisted on GLP-1RA at the last observation (80.7%) had greater HbA1c reductions. CONCLUSION Under routine care, GLP-1RA initiation frequently allowed discontinuing BBI, especially among patients with shorter disease duration, lower insulin requirement, and better glucose control.

Abstract
INTRODUCTION Combination therapy with both basal insulin (BI) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) is an effective treatment in patients with uncontrolled type 2 diabetes mellitus (T2DM). The recent development and release of a fixed-ratio combination of slow-release insulin degludec and the GLP-1RA liraglutide (IDegLira) represents an improvement to this therapy. We have conducted a real-world evidence study in Italian patients with T2DM to evaluate whether the encouraging clinical trial results obtained with IDegLira, which became available in Italy in January 2018, can be confirmed in Italian clinical practice. METHODS This was a multicenter, retrospective, observational study in patients with T2DM treated with IDegLira from January to December 2018. Prior to the initiation of IDegLira therapy, patients were treated with BI with or without one or more concomitant oral antidiabetic drugs (BOT group) or according to the basal bolus protocol (BI and rapid-acting insulin treatment; BB group). RESULTS A total of 244 patients were included in the present study, of whom 186 were in the BOT group and 58 in the BB group. Following the switch to IDegLira therapy, glycemic control improved in both groups, with significant reductions in glycated hemoglobin after 6 and 12 months of treatment in the BOT group and after 6 months of treatment in the BB group. No gain in body weight and body mass index and reductions in fasting plasma glucose and number of concomitant diabetic medications (in BOT patients) were observed. All results obtained during the study were achieved at a moderate dose of IDegLira. CONCLUSION The findings from this study show that in a real-world setting, the switch to IDegLira treatment is a valid option for patients who are failing to achieve glycemic control targets and/or struggling with the side effects, such as weight gain and hypoglycemia, of other insulin therapies.

Comparative effectiveness of dapagliflozin vs DPP-4 inhibitors on a composite endpoint of HbA1c, body weight and blood pressure reduction in the real world. Diabetes Metab Res Rev 2021; 37:e3353. [PMID: 32453482 DOI: 10.1002/dmrr.3353] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 05/06/2020] [Accepted: 05/22/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND Treatment of type 2 diabetes (T2D) should aim at preventing or delaying complications through the control of glycaemia and cardiovascular risk factors. We herein compared the SGLT-2 inhibitor dapagliflozin vs DPP-4 inhibitors (DPP-4i) on a composite endpoint of glycaemic and extraglycaemic effectiveness. METHODS This was a multicentre, retrospective real-world study conducted at 56 outpatient clinics in Italy. We collected data on patients newly started on dapagliflozin or DPP-4i in 2015-2017. The primary endpoint was the proportion of patients attaining a simultaneous reduction of HbA1c ≥0.5%, body weight ≥2 kg, systolic blood pressure (SBP) ≥2 mmHg. Confounding by indication was addressed by propensity score matching (PSM) or multivariable adjustment (MVA). RESULTS Patients initiating dapagliflozin (n = 2091) or DPP-4i (n = 2144) differed for most clinical characteristics. After PSM, two well-balanced groups of 1149 patients each were compared. The primary endpoint was reached in a greater proportion of patients who received dapagliflozin (17.6%) compared to DPP-4i (11.7%), with a relative risk of 1.50 (1.21-1.86; P < .001). Similar results were obtained in the as-treated and intention-to-treat datasets or using MVA in place of PSM. The beneficial effect of dapagliflozin was mainly due to its greater effectiveness on body weight and, to a lesser extent, on SBP. The change in HbA1c did not differ between groups. CONCLUSIONS T2D patients initiating the SGLT2i dapagliflozin had a greater probability of attaining a composite endpoint of clinically relevant reductions in HbA1c, body weight and SBP, compared to similar patients initiating a DPP-4i in the same period and healthcare setting.

Abstract
New pieces of evidence suggest that combining basal insulin with glucagone-like peptide 1 receptor agonists (GLP-1RA) in patients with type 2 diabetes could promptly ameliorate glucose control and prevent both hypoglycemic events and unnecessary weight gain compared to more intensive insulin regimens. To review the efficacy/effectiveness and safety of fixed-ratio combinations of basal insulin and GLP- 1RA (FRCs). Authors searched PubMed/MEDLINE, ClinicalTrials.gov, Cochrane Library, and Google Scholar for freely available original articles, randomized clinical trials (RCTs), clinical reviews, and meta-analysis written in English until January 2020. FRCs provide significative reductions in HbA1c levels in both insulin-naïve (-1.4% to -2%) and insulin- experienced (-1.5% to -2%) type 2 diabetic patients with moderate glucose impairment. More patients achieved the recommended glycemic targets on FRCs compared to those on mono-therapy with basal insulin or GLP-1RAs. The intensification with FRCs results in better glycemic control compared to basal insulin at fasting as well as during the postprandial state. The frequency of hypoglycemia is similar or lower in patients treated with FRCs than in those on basal insulin alone at a similar dose. Weight trend can be variable, ranging from -2.7 to +2 Kg for iDegLira and -0.7 to -1.3 Kg for iGlar- Lixi. However, a lower weight gain is obtained with iDegLira compared to iDeg (-2.2 to -2.5 Kg), iGlar (-1.7 to -3.2 Kg), and basal-bolus (-3.6 Kg) as well as with iGlarLixi compared to iGlar (-1.4 Kg). FRCs should be considered to safely improve the metabolic control in type 2 diabetic patients with moderate glycemic impairment while on oral medications, basal oral regimen or GLP-1RAs. However, a few but significative pieces of evidence suggest that FRCs could be a safe and effective treatment instead of a low dose basal-bolus intensification for patients with mild or moderate glucose impairment in order to reduce the risk of hypoglycemia and unnecessary weight gain, and for simplifying treatment regimen as well.

Abstract
CONTEXT In randomized controlled trials (RCTs) on type 2 diabetes (T2D) patients, the glucagon-like peptide-1 (GLP-1) receptor agonist (GLP-RA) dulaglutide reduced HbA1c and body weight, but generalizability of such findings to real-world T2D patients is challenging. OBJECTIVE We evaluated effectiveness of dulaglutide in routine clinical practice, especially in subgroups of patient that are underrepresented in RCTs. DESIGN Retrospective multicenter study. SETTING Diabetes outpatient clinics. PATIENTS AND INTERVENTION All consecutive patients who initiated dulaglutide between 2015 and 2018. MAIN OUTCOME MEASURES Changes in HbA1c and body weight were assessed up to 30 months after baseline. Effectiveness was analyzed in patient subgroups according to: prior use of GLP-1RA, persistence on treatment and dose, age, sex, disease duration, renal function, obesity, cardiovascular disease, or concomitant use of insulin or sulphonylurea. RESULTS From a background population of 83,116 patients, 2084 initiated dulaglutide (15.3% switching from another GLP-1RA), 1307 of whom had at least 1 follow-up visit. Overall, dulaglutide reduced HbA1c by 1.0% and body weight by 2.9 kg at the end of observation. These effects were more pronounced in GLP-1RA-naïve patients and in those with shorter disease duration. Improvement in HbA1c was highly significant and consistent across all subgroups, including those aged ≥ 75 years, nonobese, or with chronic kidney disease. Body weight declined in all subgroups and significantly more with the 1.5-mg versus 0.75-mg dose. CONCLUSIONS In real-world T2D patients, effectiveness of dulaglutide on HbA1c and body weight reduction was highly consistent and significant even in subgroups of patients poorly represented in RCTs.

Abstract
INTRODUCTION AND AIM Real-word data on the head-to-head comparisons among glucagon-like peptide-1 receptor agonists (GLP-1RA) are scant. Therefore, we aimed to compare the effectiveness of dulaglutide versus liraglutide and exenatide once weekly (exeOW) in type 2 diabetic (T2D) patients under routine care. METHODS This was a retrospective, multicenter, real-world study on patients with T2D (aged 18-80) initiating a GLP-1RA between 2010 and 2018 at specialist outpatient clinics. We compared the effectiveness of dulaglutide versus liraglutide and exeOW on the changes in HbA1c (primary outcome), body weight, blood pressure and fasting glucose (secondary outcomes). Average follow-up was 5.9 months. Channelling biases were addressed with propensity score matching or multivariable adjustment. Meta-analyses of observational studies, covering the same comparisons, are also presented. RESULTS 849, 1371 and 198 patients were included in the dulaglutide, liraglutide and exeOW groups, respectively. The reduction of HbA1c was greater with dulaglutide than with liraglutide (-0.24 ± 0.08%; p = 0.003), and was confirmed in the meta-analysis of observational studies. In our study, dulaglutide showed similar effectiveness compared to exeOW. When these results were pooled with other observational studies, dulaglutide showed a greater reduction of HbA1c (-0.19%; p = 0.003) and body weight (-0.8 kg; p = 0.007). CONCLUSIONS In a real-world scenario, dulaglutide reduced HbA1c more than liraglutide. Conversely, we found similar effect of dulaglutide and exeOW, with statistical differences arising solely when results were meta-analysed with those from other observational studies. Lack of up-titration for liraglutide and higher discontinuation rate for exeOW likely influenced the estimated treatment difference.

Abstract
AIM To evaluate the generalizability of cardiovascular outcome trials (CVOTs) on glucagon-like peptide-1 receptor agonists (GLP-1RAs), we assessed what proportion of real-world patients with type 2 diabetes (T2D) constitute true CVOT-like populations. MATERIALS AND METHODS We applied inclusion/exclusion (I/E) criteria of each GLP-1RA CVOT to a cross-sectional database of 281 380 T2D patients from Italian diabetes outpatient clinics. We calculated the proportion of patients eligible for each CVOT and compared their clinical characteristics with those of trial patients. In addition, we used a Bayesian network-based method to sample the greatest subsets of real-world patients yielding true CVOT-like populations. RESULTS Between 98 725 and 124 164 T2D patients could be evaluated for CVOT eligibility. After excluding patients who were already on GLP-1RAs and applying I/E criteria, 35.8% of patients would be eligible for REWIND, 34.1% for PIONEER-6, 13.4% for EXSCEL, 10.1% for SUSTAIN-6, 9.5% for HARMONY and 9.4% for LEADER. Overall, 45.4% of patients could be eligible for at least one of the CVOTs. These patients, however, were extremely different to trial patients in most of the clinical characteristics, including demographics, concomitant medications and complications. The greatest CVOT-like subsets of real-world patients were 0.5% for SUSTAIN-6, 1.0% for EXSCEL, 1.2% for LEADER, 1.8% for PIONEER-6 and 7.9% for REWIND. CONCLUSIONS A very small proportion of real-world patients constitute true CVOT-like populations. These findings question whether any meaningful information can be drawn from applying trial enrolment criteria to real-world T2D patients.

Abstract
AIMS Several GLP-1 receptor agonists (GLP-1RA) have become available for the treatment of type 2 diabetes (T2D), and evidence on their beneficial effects has evolved. We evaluated how the clinical phenotype of patients initiating GLP-1RA changed from 2010 to 2018. METHODS This was a retrospective study conducted at six diabetes outpatient clinics in Northeast Italy. We collected data of T2D patients who initiated new GLP-1RA between 2010 and 2018. We recorded baseline characteristics, including demographics, anthropometrics, cardiovascular risk factors, glucose control, lipid profile, liver enzymes, renal function and concomitant medications. We recorded updated HbA1c and body weight at follow-up. RESULTS There were 83,116 T2D patients from a general population of ~ 1,380,000 inhabitants. Among 6167 cases of GLP-1RA initiation, 5408 were analyzed after excluding intra-class switchers. Prescription of GLP-1RA increased exponentially, and the change in the type of GLP-1RA reflected waves of their entering the market. From 2010 to 2018, there were significant increases in baseline age, diabetes duration and prevalence of male sex, of cardiovascular disease and of insulin users. Blood pressure and cholesterol levels decreased concomitantly with increasing use of medications for the control of cardiovascular risk. Baseline average HbA1c (8.3% [67 mmol/mol]) and BMI (34 kg/m2) and their improvement after GLP-1RA initiation did not change over time. CONCLUSIONS Despite the early positioning of GLP-1RA in T2D treatment algorithms, GLP-1RA have been prescribed in patients with progressively more advanced disease stage and especially in the presence of cardiovascular disease. Optimization of GLP-1RA use in routine clinical practice is still needed.

Abstract
Randomized controlled trials (RCTs) have consistently shown glycemic and extra-glycemic benefits of long-acting injectable glucagon-like-peptide-1 receptor agonists (GLP-1RAs, liraglutide, albiglutide, exenatide once-weekly, dulaglutide, and semaglutide) in terms of reduction in the rates of cardiovascular events and mortality among patients with type 2 diabetes. Recently, the analyses of large datasets collecting routinely-accumulated data from clinical practice (ie, real-world studies, RWS) have provided new opportunities to complement the information obtained from RCTs. In this narrative review, we addressed clinically relevant questions that might be answered by well-conducted RWS: are subjects treated with GLP-1RAs in the "real-world" similar to those included in RCTs? Is the performance of GLP-1RA observed in the RWS (effectiveness) similar to that described in RCTs (efficacy)? Is the effectiveness similar in population of patients generally under-represented in RCTs? Are the cardiovascular benefits of GLP-1RAs confirmed in RWS? We also describe a few comparisons currently un-explored by specific RCTs, such as direct comparison between different administration strategies (eg, fixed- versus flexible-combination with basal-insulin) or between GLP-1RAs versus dipeptidyl-peptidase-4 inhibitor (DDP4i) or versus sodium/glucose cotransporter-2 inhibitors (SGLT-2i) on hard cardio-renal outcomes. Altogether, RWS provide highly informative information on treatment with GLP-1RAs. On the one side, RWS showed different clinical characteristics between subjects enrolled in RCTs versus those attending real-world clinics and receiving a GLP-1RA. On the other hand, RWS showed that GLP-1RA effectiveness is overall consistent in subgroups of patients less represented in RCTs. In addition, RWS allowed the identification of modifiable factors (eg, titration or adherence) that might guide physicians towards better GLP-1RAs use. Finally, multiple RWS reported better cardio-renal outcomes with GLP-1RAs than with DPP-4i, while initial findings from RWS described a weaker cardiovascular protection compared to SGLT-2i. Therefore, there is the need for further RWS and RCTs comparing these different classes of glucose lowering medications.

Fixed versus flexible combination of GLP-1 receptor agonists with basal insulin in type 2 diabetes: A retrospective multicentre comparative effectiveness study. Diabetes Obes Metab 2019; 21:2542-2552. [PMID: 31364233 PMCID: PMC6852173 DOI: 10.1111/dom.13840] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2019] [Revised: 07/08/2019] [Accepted: 07/25/2019] [Indexed: 12/18/2022]
Abstract
BACKGROUND AND AIMS The combination of basal insulin (BI) and GLP-1 receptor agonists (GLP-1RAs) is a rational and effective therapy for patients with uncontrolled type 2 diabetes (T2D). We compared the effectiveness of fixed and flexible BI/GLP-1RA combinations using routinely accumulated clinical data. METHODS This was a retrospective, multicentre, real-world study concerning T2D patients initiating a fixed or flexible BI/GLP-1RA combination (NCT03959865). The primary endpoint was change in HbA1c. Secondary endpoints were changes in body weight, fasting plasma glucose (FPG) and systolic blood pressure (SBP). Confounding was addressed by propensity score matching (PSM) or multivariable adjustment (MVA). RESULTS A total of 609 patients were included in the study, 131 in the fixed group and 478 in the flexible group. The two groups differed in terms of diabetes duration, body weight and concomitant medications. After 5.7 months, observed HbA1c reductions were 0.6% and 0.8%, and body weight reductions were 2.8 kg and 1.2 kg in the flexible and fixed groups, respectively. Following PSM, HbA1c declined similarly in the two groups, whereas reduction in body weight was significantly in favour of the flexible combination. Findings were robust in sensitivity analyses, with the exception that, with MVA, a significantly higher reduction in HbA1c was detected in the fixed group. Final doses of BI were higher in the fixed group, whereas those of GLP-1RA were higher in the flexible group. CONCLUSIONS In routine specialist care, initiation of the fixed or flexible BI/GLP-1RA combination allowed similar improvement in glycaemic control, but greater weight loss was observed with the flexible combination. This difference reflected dosages of BI and GLP-1RAs.
