Diabetes Ther 2025:10.1007/s13300-025-01741-8. [PMID: 40377834 DOI: 10.1007/s13300-025-01741-8] [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: 01/27/2025] [Accepted: 04/10/2025] [Indexed: 05/18/2025] Open
Abstract
INTRODUCTION This study evaluated healthcare resource utilization (HCRU) and costs in the USA for people with type 2 diabetes (T2D) who discontinued the injectable glucagon-like peptide 1 receptor agonist (GLP-1 RA) once-daily liraglutide for T2D (with no other glucose-lowering agent added) or switched from liraglutide to the GLP-1 RA once-weekly semaglutide for T2D. METHODS In this observational cohort study, we utilized claims data (Merative MarketScan [Merative, Ann Arbor, MI, USA] Commercial and Medicare Database; January 1, 2017-March 31, 2021) to compare HCRU and costs between individuals who discontinued liraglutide ("discontinuers") and those who switched from liraglutide to semaglutide ("switchers"). Patients were indexed between January 1, 2018 and March 31, 2020. Outcomes were compared between discontinuers and switchers over the 360-day post-index period using stabilized inverse probability of treatment weighting. RESULTS Characteristics of the two cohorts were balanced after weighting. Switchers had significantly lower HCRU in inpatient and emergency department (ED) settings compared with discontinuers. Mean [standard deviation] total medical costs were significantly lower for switchers ($8513 [$18,931]) than for discontinuers ($13,585 [$52,011], p < 0.001), driven by reduced inpatient costs (2.6 times lower) and ED costs (1.6 times lower). CONCLUSION This analysis demonstrates that the cohort of people switching from liraglutide to semaglutide was associated with significantly lower HCRU and costs when compared with people discontinuing liraglutide only. These findings imply that switching to semaglutide could be a good option for people with T2D for whom liraglutide is no longer optimal.

Abstract
Background Poor adherence to antihypertensive medication remains a significant barrier to blood pressure control in young patients. The objective of this study was to identify factors associated with antihypertensive medication adherence among young adults with hypertension. Methods From the Korean National Health Insurance Service database, we included 141,132 participants aged 20 to 39 years (80.4% male), without cardiovascular disease, who initiated antihypertensive medication between 2013 and 2018. Participants were categorized as exhibiting good adherence (proportion of days covered [PDC] ≥ 0.8) or poor adherence (PDC < 0.8) to antihypertensive medication during the first year of treatment. We investigated the associations of demographic, lifestyle, and clinical factors with good medication adherence based on logistic regression analysis. Results Only 43.3% (n = 61,107) of young adults with hypertension showed good adherence to antihypertensive medication. Male sex, older age, higher income, urban residence, non-smoking, and higher physical activity were associated with good medication adherence. Initial combination therapy, especially with single-pill combination (odds ratio [OR], 1.12; 95% confidence interval [CI], 1.07-1.18), was associated with good adherence. Among patients under monotherapy, initial use of renin-angiotensin blockers (OR, 5.24; 95% CI, 4.47-6.15) or calcium-channel blockers (OR, 4.07; 95% CI, 3.47-4.78) was associated with better adherence than initial diuretics. Conclusions Although antihypertensive medication adherence is generally poor among young adults, we identified potential demographic and clinical factors associated with good adherence to antihypertensive treatment. Initial use of a single-pill combination may promote adherence in young patients, and its long-term clinical outcomes warrant further investigation.

Unlocking the potential of glucagon-like peptide-1 receptor agonists in revolutionizing type 2 diabetes management: a comprehensive review. Ann Med Surg (Lond) 2024; 86:7255-7264. [PMID: 39649934 PMCID: PMC11623894 DOI: 10.1097/ms9.0000000000002712] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2024] [Accepted: 10/25/2024] [Indexed: 12/11/2024] Open
Abstract
Diabetes mellitus (DM) is a long-term metabolic disorder caused by inadequate production and resistance to insulin. The prevalence of DM is rapidly increasing, with type 2 diabetes (T2D) accounting for more than 90% of cases. Despite new treatments, many patients with T2D do not meet their glycemic targets due to clinical inertia. This review provides an overview of glucagon-like peptide 1 receptor agonists (GLP-1 RAs) in the management of T2D. The review synthesizes data from clinical trials and meta-analyses on the efficacy, safety, and cost-effectiveness of GLP-1 RAs. It also discusses the mechanisms of action, classification, and barriers to adherence and persistence in therapy. GLP-1 RAs improve glycemic control by lowering A1C levels and promoting weight loss. They have cardioprotective effects and may reduce endothelial inflammation, oxidative stress, and blood pressure. Adherence to GLP-1 RAs is better with once-weekly injections, though gastrointestinal side effects and cost can affect persistence. Semaglutide and liraglutide have shown significant weight reduction, with semaglutide being particularly effective. GLP-1 RAs are cost-effective due to reduced healthcare costs associated with fewer hospitalizations and lower mortality rates. Safety concerns include gastrointestinal issues, pancreatitis, and rare cases of diabetic retinopathy and thyroid C-cell tumors. For clinical practice, GLP-1 RAs represent a valuable option not only for glycemic control but also for weight management and cardiovascular protection. Incorporating GLP-1 RAs into treatment plans can improve patient outcomes, and optimizing dosing regimens and addressing barriers such as cost and side effects are crucial to enhancing patient adherence and long-term treatment success.

Abstract
AIMS To investigate real-world treatment adherence and persistence in people with type 2 diabetes newly initiating oral semaglutide, a glucagon-like peptide-1 receptor agonist (GLP-1 RA), or a dipeptidyl peptidase-4 inhibitor (DPP-4i). METHODS This retrospective cohort study used the Merative™ MarketScan® Commercial and Medicare databases. Index date was the first fill for the cohort medication. Adherence was defined as proportion of days covered (PDC) over the 12-month post-index period ('adherent' = ≥0.8). Persistence was number of days until discontinuation, based on a 45-day gap. Results were compared between cohorts using inverse probability treatment weighting. RESULTS Oral semaglutide (n=5485) and DPP-4i (n=4980) cohorts had similar percentages of people who were adherent (PDC ≥0.8; 41.6 % vs. 42.9 %; P = 0.182) and persistent for ≥9 months (45.0 % vs. 46.3 %; P = 0.185). The DPP-4i cohort used significantly more anti-diabetic medication (ADM) classes over the post-index period (mean±SD: 2.6±1.0 vs. 2.9±1.1, P < 0.001), with 23.2 % filling a GLP-1 RA in the post-period. CONCLUSIONS Adherence and persistence were similar between cohorts. However, there are potential benefits to prescribing oral semaglutide over DPP-4is, including reduced need for additional ADM.

Greater persistence and adherence to basal insulin therapy is associated with lower healthcare utilization and medical costs in patients with type 2 diabetes: a retrospective database analysis. BMJ Open Diabetes Res Care 2024; 12:e003825.

Abstract
INTRODUCTION We aimed to assess persistence and adherence to basal insulin therapy, their association with all-cause healthcare resource utilization (HCRU) and direct medical costs, and predictors of persistence and adherence in adults with type 2 diabetes. RESEARCH DESIGN AND METHODS A retrospective cohort study was conducted with US adults with type 2 diabetes initiating basal insulin therapy between January 1, 2016, and December 31, 2018, using IQVIA PharMetrics Plus claims data. Persistence and adherence were assessed during 1 year post-initiation per previous definitions. Demographic/clinical characteristics were assessed during the 1 year pre-initiation. Inverse probability of treatment weighting (IPTW) was used to adjust for confounding variables. Post-IPTW, all-cause HCRU and direct medical costs were assessed during the first-year and second-year post-initiation by persistence and adherence status. Multivariable logistic regression was used to identify predictors of persistence and adherence. RESULTS The final sample comprised 64,953 patients; 56.8% demonstrated persistence and 41.9% demonstrated adherence. Patients demonstrating persistence and adherence were significantly less likely to have a hospitalization than patients demonstrating non-persistence or non-adherence, respectively. In the second-year post-initiation, total mean all-cause direct medical costs per patient were lower for patients demonstrating persistence and significantly lower for patients demonstrating adherence. Prior use of both oral and injectable antidiabetic medication predicted persistence and adherence compared with patients with only prior oral antidiabetic medication use (persistence OR, 1.50 (95% CI, 1.44 to 1.57); adherence OR, 1.48 (95% CI, 1.42 to 1.55)). CONCLUSIONS Persistence and adherence to basal insulin was associated with fewer hospitalizations and lower direct medical costs.

Abstract
AIMS To present the final results of the TROPHIES study (The real-world observational prospective study of health outcomes with dulaglutide and liraglutide in patients with type 2 diabetes). MATERIALS AND METHODS The prospective, real-world TROPHIES study included patients with type 2 diabetes initiating their first injectable glucose-lowering medication (GLM), dulaglutide or liraglutide, in France, Germany and Italy. The primary endpoint was the time spent on dulaglutide or liraglutide until a significant treatment change over 24 months. Other endpoints measured persistence with treatment, clinical outcomes (glycated haemoglobin [HbA1c] and weight) and treatment patterns. Kaplan-Meier estimates of time to first significant treatment change and persistence with treatment were generated. Propensity-score-based inverse probability of treatment weighting (IPTW) was used to adjust for baseline imbalances in the comparison between cohorts. RESULTS The 286 of 1014 patients (28.2%) in the dulaglutide cohort and 448 of 991 patients (45.2%) in the liraglutide cohort had a significant treatment change over 24 months. By IPTW analysis, dulaglutide-initiating patients were less likely to have a significant treatment change (hazard ratio [HR] 0.54, 95% confidence interval [CI] 0.46-0.63) and more likely to be persistent with treatment (HR 0.69, 95% CI 0.56-0.86) over 24 months than liraglutide-initiating patients. Dulaglutide and liraglutide yielded similar HbA1c (-11.80 mmol/mol [1.08%] and -11.91 mmol/mol [1.09%]) and weight (-3.5 kg and -3.3 kg) reductions from baseline to 24 months. Few changes in patterns of treatment with other GLMs were observed in the two cohorts. CONCLUSIONS Dulaglutide-initiating patients had a longer time spent without any significant treatment change and higher persistence than those initiating liraglutide. Treatment with either glucagon-like peptide-1 receptor agonist yielded similar and clinically meaningful reductions in HbA1c and body weight.

Abstract
OBJECTIVES This study aims to evaluate the cost-effectiveness of various glucose-lowering therapies as add-on to standard care for people with type 2 diabetes (T2D) in Malaysia. METHODS A state-transition microsimulation model was developed to compare the clinical and economic outcomes of 4 treatments: standard care, dipeptidyl peptidase-4 inhibitors, sodium-glucose cotransporter-2 inhibitors (SGLT2is), and glucagon-like peptide-1 receptor agonists. Cost-effectiveness was assessed from a healthcare provider's perspective over a lifetime horizon with 3% discount rate in a hypothetical cohort of people with T2D. Data input were informed from literature and local data when available. Outcome measures include costs, quality-adjusted life-years, incremental cost-effectiveness ratios, and net monetary benefits. Univariate and probabilistic sensitivity analyses were performed to assess uncertainties. RESULTS Over a lifetime horizon, the costs to treat a person with T2D ranged from RM 12 494 to RM 41 250, whereas the QALYs gains ranged from 6.155 to 6.731, depending on the treatment. Based upon a willingness-to-pay threshold of RM 29 080 per QALY, we identified SGLT2i as the most cost-effective glucose-lowering treatment, as add-on to standard care over patient's lifetime, with the net monetary benefit of RM 176 173 and incremental cost-effectiveness ratios of RM 12 279 per QALY gained. The intervention also added 0.577 QALYs and 0.809 LYs compared with standard care. Cost-effectiveness acceptability curve showed that SGLT2i had the highest probability of being cost-effective in Malaysia across varying willingness-to-pay threshold. The results were robust to various sensitivity analyses. CONCLUSIONS SGLT2i was found to be the most cost-effective intervention to mitigate diabetes-related complications.

Abstract
Purpose Treatment process attributes can affect health state utilities associated with therapy. For intravenous iron, used to treat iron deficiency and iron deficiency anemia, research into process attributes is still lacking. This study estimated utilities associated with process attributes for intravenous iron infusions. Methods An online survey including seven health state vignettes and time trade-off tasks was administered to participants, who were not patients living with iron deficiency or iron deficiency anemia, from a Chinese online panel. Vignettes used an identical description of iron deficiency and iron deficiency anemia but differed in the annual number of infusions, infusion duration, and infusion-associated risk of hypophosphatemic osteomalacia. Disutilities and their rate of change as the number of infusions increased were examined using a power model. Results The survey was completed by 1091 participants. The highest utilities were observed for one annual infusion of 15-30 minutes or 30-60 minutes, without risk of hypophosphatemic osteomalacia (0.754 and 0.746, respectively). In comparison, more infusions and infusions with a risk of hypophosphatemic osteomalacia were associated with lower utilities. Utility continued to decrease, but at a diminishing rate, as the annual number of infusions increased, with utility decrements of 0.006 and 0.002, respectively, when going from zero to one and from four to five infusions per year. All marginal disutilities were small (values <0.01). Conclusion This study suggested that treatment attributes of intravenous iron infusions affect health state utilities. Using intravenous iron formulations that allow for fewer and shorter infusions without the risk of hypophosphatemic osteomalacia can reduce the number of visits required and increase patients' quality of life.

Abstract
INTRODUCTION In type 2 diabetes (T2D), key barriers to optimal glycaemic control include lack of persistence with treatment, reduced medication adherence and therapeutic inertia. This study aimed to assess the impact of these barriers in obese adults with type 2 diabetes treated with a GLP-1 receptor agonist (GLP-1RA) and compare them against other glucose-lowering agents in a real-world setting. METHODS A retrospective study was conducted using electronic medical records from 2014 to 2019 for adults with T2D at the Valencia Clínico-Malvarrosa Department of Health (Valencia, Spain). Four study groups were established: all GLP-1RA users, SGLT2i users, insulin users and other glucose-lowering agent users (miscellany group). To account for imbalance between groups, propensity score matching (PSM) including age, gender and pre-existing cardiovascular disease was performed. Chi-square tests were used for comparisons between groups. Time to first intensification was calculated using competing risk analysis. RESULTS Among the 26,944 adults with T2D, 7392 individuals were selected following PSM, with 1848 patients in each group. At 2 years, GLP-1RA users were less persistent than non-users (48.4% versus 72.7%, p < 0.0001) but more adherent (73.8% versus 68.9%, respectively, p < 0.0001). A greater proportion of persistent GLP-1RA users than non-persistent users exhibited reduced HbA1c (40.5% versus 18.6%, respectively, p < 0.0001), but no differences in cardiovascular outcomes and death were found. Overall, therapeutic inertia was observed in 38.0% of the study population. The large majority of GLP-1RA users received treatment intensification, whereas only 50.0% of GLP-1RA non-users were intensified. CONCLUSION Under real-life conditions, obese adults with T2D persistently treated with GLP-1RA showed improved glycaemic control. Despite benefits, persistence with GLP-1RA was limited after 2 years. Additionally, therapeutic inertia occurred in two out of three study participants. Strategies to facilitate medication adherence, persistence and treatment intensification in people with T2D should be made a priority in order to achieve and maintain glycaemic targets and improve outcomes in this population.

Jung H, Tittel SR, Schloot NC, Heitmann E, Otto T, Lebrec J, Pavel M, Lanzinger S. Clinical characteristics, treatment patterns, and persistence in individuals with type 2 diabetes initiating a glucagon-like peptide-1 receptor agonist: A retrospective analysis of the Diabetes Prospective Follow-Up Registry. Diabetes Obes Metab 2023. [PMID: 36855221 DOI: 10.1111/dom.15038] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 02/22/2023] [Accepted: 02/24/2023] [Indexed: 03/02/2023]
Abstract
AIMS To describe clinical characteristics, treatment patterns and glucagon-like peptide-1 receptor agonist (GLP-1 RA) persistence in individuals with type 2 diabetes (T2D) initiating their first GLP-1 RA. MATERIALS AND METHODS A real-world analysis of adults with T2D initiating GLP-1 RA therapy between 2007 and June 2020 from the multicentre Diabetes Prospective Follow-Up (DPV) Registry, stratified by antidiabetes therapy at the time of GLP-1 RA initiation: oral antidiabetic drugs (OAD), insulin ± OAD or lifestyle modification (LM). GLP-1 RA treatment persistence in individuals with ≥12 months follow-up was determined by Kaplan-Meier analysis. RESULTS Overall, 15 111 individuals with T2D initiating GLP-1 RA therapy (55% men) were identified; median [interquartile range (IQR)] age [58.7 (50.6-66.7) years], diabetes duration [8.5 (3.6-14.7) years], glycated haemoglobin [HbA1c; 8.2 (7.1-9.8)%]. Median (95% confidence interval) GLP-1 RA persistence in eligible individuals (n = 5189) was 11 (10-12) months; OAD 12 (11-14) months (n = 2453); insulin ± OAD 11 (9-12) months (n = 2204); and LM 7 (5-9) months (n = 532). Median treatment persistence tended to increase from 2007-2012 to 2017-2020. Median (IQR) HbA1c decreased from baseline [8.2 (7.1-9.8)%] to discontinuation [7.5 (6.6-8.7)%], with a greater decrease observed in individuals with persistence >12 months versus ≤12 months. Individuals who discontinued GLP-1 RA therapy predominantly switched to insulin (if not already using) or dipeptidyl peptidase-4 inhibitors. CONCLUSION Real-world registry data revealed improved outcomes with longer median GLP-1 RA persistence; ~50% of patients overall achieved HbA1c <7% at 12 months. Persistence was highest with baseline OAD and/or insulin, and tended to increase over the period 2007-2020.

A Study on Weight Loss Cause as per the Side Effect of Liraglutide. Cardiovasc Ther 2022; 2022:5201684. [PMID: 36540096 PMCID: PMC9733986 DOI: 10.1155/2022/5201684] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Accepted: 10/10/2022] [Indexed: 12/04/2022] Open
Abstract
Purpose Liraglutide is known to have much lower weight loss effects in real clinical fields than in randomized clinical trials because of its side effects (SE) and discomfort associated with injections. This study is aimed at determining whether the side effects of liraglutide affect weight reduction and its maintenance in real-world practice. Methods Endocrinologists conducted a retrospective chart review of data from two tertiary university hospitals. All patients who had been prescribed liraglutide at least once between January 2014 and December 2019 were included. For an average of 3 and 6 months, weight changes due to the presence or absence of SE and discontinuation (MAIN or STOP) of liraglutide were checked. Results Only 40.8% (64/157) of the patients remained on liraglutide for 6 months; 14.7% (23/157) maintained the drug despite SEs (MAIN_SE(+)), and 40.1% (63/157) discontinued the drug despite not having SEs (STOP_SE(-)). At 3 months, there was -5.9 ± 0.6%, -7.9 ± 0.9%, -4.5 ± 0.5%, and -3.4 ± 0.6% weight reduction in the MAIN_SE(-), MAIN_SE(+), STOP_SE(-), and STOP_SE(+) groups, respectively (all p < 0.001 compared to the baseline). However, there were no significant differences in the weight loss between the MAIN (p = 0.062) and STOP (p = 0.204) groups. At 6 months, the weight reduction was -2.0 ± 0.5% (p < 0.001) in MAIN_SE(-), -2.2 ± 0.7% (p < 0.005) in MAIN_SE(+), -1.7 ± 0.7% (p < 0.01) in STOP_SE(-), and -2.0 ± 0.6% (p = 0.01) in STOP_SE(+), compared to baseline. SEs also caused no significant differences in weight loss between the MAIN (p = 0.787) and STOP (p = 0.694) groups. Conclusions Our study confirmed that the side effects of liraglutide did not affect weight reduction. Moreover, in the real world, the continuous rate of liraglutide use is not high, and the weight gradually increases after 3 months. Therefore, in addition to the side effects of liraglutide, the medical staff should consider various factors that affect drug adherence, consider ways to increase compliance, and continue to ensure management so that patients can maintain their weight.

[PMID: 36399483 PMCID: PMC9674161 DOI: 10.1371/journal.pone.0272057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Accepted: 07/12/2022] [Indexed: 11/19/2022] Open
Abstract
The purpose of this study is to empirically examine the relationships between service quality, patient satisfaction, patient loyalty and medication adherence in the Syrian healthcare setting from a patient's perspective. Based on random sampling technique, data collection was conducted in six hospitals located in the Syrian capital Damascus. The reliability and validity of the theoretical model had been confirmed using quantitative analyses SmartPLS software. The study indicated that our proposed model can significantly explain (35) per cent of patient satisfaction, (55) per cent of patient loyalty and (46) per cent medication adherence in a statistically manner. Our results highlighted that patient satisfaction mediated the relationship between patient loyalty and service quality (assurance, reliability and financial aspect). Besides, patient satisfaction had mediation effect on the relationship between medication adherence and service quality (reliability and financial aspect). Financial aspect had the highest impact on patient satisfaction (β = 0.242) and medication adherence (β = 0.302). In addition, reliability was the only dimension of service quality that had a significant direct impact on patient satisfaction, patient loyalty and medication adherence. To increase patient loyalty in Syrian hospitals, healthcare professionals should place a greater emphasis on the reliability and responsiveness elements of service quality. To the author's knowledge, this is the first study conducted during the COVID pandemic to evaluate the mediating role of patient satisfaction in the relationship between service quality, patient loyalty and medication adherence in the Syrian healthcare sector.

Detecting Medication-Taking Gestures Using Machine Learning and Accelerometer Data Collected Via Smartwatch Technology: A Feasibility Study (Preprint). JMIR Hum Factors 2022; 10:e42714. [PMID: 37140971 DOI: 10.2196/42714] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Revised: 01/10/2023] [Accepted: 02/11/2023] [Indexed: 02/13/2023] Open
Abstract
BACKGROUND Medication adherence is a global public health challenge, as only approximately 50% of people adhere to their medication regimens. Medication reminders have shown promising results in terms of promoting medication adherence. However, practical mechanisms to determine whether a medication has been taken or not, once people are reminded, remain elusive. Emerging smartwatch technology may more objectively, unobtrusively, and automatically detect medication taking than currently available methods. OBJECTIVE This study aimed to examine the feasibility of detecting natural medication-taking gestures using smartwatches. METHODS A convenience sample (N=28) was recruited using the snowball sampling method. During data collection, each participant recorded at least 5 protocol-guided (scripted) medication-taking events and at least 10 natural instances of medication-taking events per day for 5 days. Using a smartwatch, the accelerometer data were recorded for each session at a sampling rate of 25 Hz. The raw recordings were scrutinized by a team member to validate the accuracy of the self-reports. The validated data were used to train an artificial neural network (ANN) to detect a medication-taking event. The training and testing data included previously recorded accelerometer data from smoking, eating, and jogging activities in addition to the medication-taking data recorded in this study. The accuracy of the model to identify medication taking was evaluated by comparing the ANN's output with the actual output. RESULTS Most (n=20, 71%) of the 28 study participants were college students and aged 20 to 56 years. Most individuals were Asian (n=12, 43%) or White (n=12, 43%), single (n=24, 86%), and right-hand dominant (n=23, 82%). In total, 2800 medication-taking gestures (n=1400, 50% natural plus n=1400, 50% scripted gestures) were used to train the network. During the testing session, 560 natural medication-taking events that were not previously presented to the ANN were used to assess the network. The accuracy, precision, and recall were calculated to confirm the performance of the network. The trained ANN exhibited an average true-positive and true-negative performance of 96.5% and 94.5%, respectively. The network exhibited <5% error in the incorrect classification of medication-taking gestures. CONCLUSIONS Smartwatch technology may provide an accurate, nonintrusive means of monitoring complex human behaviors such as natural medication-taking gestures. Future research is warranted to evaluate the efficacy of using modern sensing devices and machine learning algorithms to monitor medication-taking behavior and improve medication adherence.

Patient Relat Outcome Meas 2022; 13:97-111. [PMID: 35586269 PMCID: PMC9109803 DOI: 10.2147/prom.s322390] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Accepted: 04/07/2022] [Indexed: 11/30/2022] Open
Abstract
Introduction Treatment-related attributes and process characteristics such as dosing frequency, timing flexibility, ease of use of injection devices and unpleasant side-effects may have small but measurable effects on quality of life (QoL) in people with type 2 diabetes (T2D). A literature review was performed to identify recently published utility values quantifying the effect of treatment-related attributes on QoL. Methods Literature search strategies were designed using high-level medical subject heading (MeSH) terms supplemented with free-text terms and searches were run in March 2020 in the PubMed, Embase and Cochrane Library databases. For inclusion, studies were required to be published in full-text form, in English, since 2010 and report utility values (elicited using either direct or indirect methods) for treatment-related attributes or process characteristics including side effects, change in weight/body mass index (BMI), dosing frequency and timing flexibility, device attributes (e.g. needle handling, requirement for reconstitution) and convenience (e.g. waiting time). Results A total of 30 studies were included in the review, of which all but three were conducted in people with T2D. The EQ-5D was the most commonly used elicitation method (fourteen studies), followed by time tradeoff (TTO) methodology. Treatment-related adverse events and inconveniences such as needle handling in administration devices and waiting time were consistently associated with lower QoL, whereas lower dosing frequency and increased timing flexibility with dosing were consistently associated with utility benefits. The relationship between change in BMI and QoL was non-linear and influenced by baseline BMI. Conclusion Treatment-related attributes and process characteristics are associated with minor changes in QoL, which should be taken into account in long-term health economic modeling of new treatments and administration devices.

Greater Adherence and Persistence with Injectable Dulaglutide Compared with Injectable Semaglutide at 1-Year Follow-up: Data from US Clinical Practice. Clin Ther 2022; 44:537-554. [PMID: 35264311 DOI: 10.1016/j.clinthera.2022.01.017] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 12/20/2021] [Accepted: 01/28/2022] [Indexed: 11/29/2022]
Abstract
PURPOSE Greater medication adherence and persistence have been associated with improved glycemic control in patients with type 2 diabetes mellitus. This study compared adherence, persistence, and treatment patterns among patients naïve to glucagon-like peptide 1 receptor agonists initiating once-weekly injectable treatment with dulaglutide versus semaglutide over 6-month (6M) and 12-month (12M) follow-up periods. METHODS This retrospective, observational cohort study used administrative claims data from three IBM MarketScan research databases. Data from adult patients with type 2 diabetes newly initiating treatment with dulaglutide or semaglutide between January 2018 and January 2020 (index date was defined as the earliest fill date), without evidence of glucagon-like peptide 1 receptor agonist use in the 6M baseline period, and with continuous enrollment in the 6M baseline and 6M or 12M follow-up period were included. Dulaglutide initiators were propensity score-matched, in a 1:1 ratio, to semaglutide initiators in each 6M and 12M follow-up cohort (26,284 and 13,837 pairs, respectively). FINDINGS In the matched cohorts, baseline characteristics were balanced; the mean age was 53 years, and 50% of patients were women. Compared to semaglutide initiators, dulaglutide initiators were more adherent (6M, 63.4% vs 47.8%; 12M, 54.4% vs 43.3%; both, P < 0.0001), more persistent on therapy (6M, 72% vs 62%, 12M, 55.5% vs 45.3%, both, P < 0.001), and had more mean days of persistence (6M, 145 vs 132, 12M, 254.3 vs 220.7; both, P < 0.001). IMPLICATIONS At both 6M and 12M follow-up, dulaglutide initiators had significantly greater adherence and greater persistence compared with matched semaglutide initiators.

Adherence to and persistence with antidiabetic medications and associations with clinical and economic outcomes in people with type 2 diabetes mellitus: A systematic literature review. Diabetes Obes Metab 2022; 24:377-390. [PMID: 34779107 PMCID: PMC9299643 DOI: 10.1111/dom.14603] [Citation(s) in RCA: 31] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Revised: 10/21/2021] [Accepted: 10/31/2021] [Indexed: 12/28/2022]
Abstract
We designed a systematic literature review to identify available evidence on adherence to and persistence with antidiabetic medication in people with type 2 diabetes (T2D). Electronic screening and congress searches identified real-world noninterventional studies (published between 2010 and October 2020) reporting estimates of adherence to and persistence with antidiabetic medication in adults with T2D, and associations with glycaemic control, microvascular and/or macrovascular complications, hospitalizations and healthcare costs. Ninety-two relevant studies were identified, the majority of which were retrospective and reported US data. The proportions of patients considered adherent (median [range] 51.2% [9.4%-84.3%]) or persistent (median [range] 47.7% [16.9%-94.0%]) varied widely across studies. Multiple studies reported an association between greater adherence/persistence and greater reductions in glycated haemoglobin levels. Better adherence/persistence was associated with fewer microvascular and/or macrovascular outcomes, although there was little consistency across studies in terms of which outcomes were improved. More adherent and more persistent patients were typically less likely to be hospitalized or to have emergency department visits/admissions and spent fewer days in hospital annually than less adherent/persistent patients. Greater adherence and persistence were generally associated with lower hospitalization costs, higher pharmacy costs and lower or budget-neutral total healthcare costs compared with lower adherence/persistence. In conclusion, better adherence and persistence in people with T2D is associated with lower rates of microvascular and/or macrovascular outcomes and inpatient hospitalization, and lower or budget-neutral total healthcare expenditure. Education and treatment strategies to address suboptimal adherence and persistence are needed to improve clinical and economic outcomes.

Abstract
INTRODUCTION The aim of the project was to describe the preferences related to the medication attributes of people with diabetes mellitus (DM) treated in Spain. METHODS The project was carried out in four different phases. In phase A, a Steering Committee defined and selected a total of 18 attributes for treating DM and grouped them into four categories: health outcomes, adverse events, treatment characteristics and cost of treatment. In phase B, a questionnaire according to a discrete choice experiment (DCE) methodology was developed. In phase C, the online DCE survey was sent to members of associations of people with DM from the Spanish Diabetes Federation (FEDE). Finally, in phase D, the results were discussed in a deliberative process. RESULTS Of the 238 participants who completed the questionnaire (May-September 2020), 231 were included (mean age, 58 years; males, 62%). The DCE results showed that the best-valued category was health outcomes (39.67%), followed by adverse events (26.85%), treatment characteristics (21.70%) and treatment costs (11.77%). Ten of 18 attributes had a significant effect on participants' choice (p < 0.05) and the highest relative importance value: blood pressure reduction (12.82%), hypoglycaemia (12.77%), HbA1c level reduction (8.54%), cost of the medication (8.13%), needle/tablet size (7.20%), weight change (6.72%), risk of genitourinary infections (6.36%), gastrointestinal problems (5.82%), improved kidney function (5.53%) and administration route (5.41%). CONCLUSIONS People with DM prefer a treatment that generates benefits in measurable health effects (reducing blood pressure and HbA1c level, while not risking hypoglycaemia) and a convenient route of administration. Considering the preferences of people with DM could generate better clinical results and therapeutic adherence, reducing morbidity, mortality and disease burden.

Abstract
INTRODUCTION Once-weekly (OW) semaglutide was associated with clinically relevant improvements in glycaemic control and body weight versus comparators in the SUSTAIN randomised controlled trials (RCTs). SURE UK, which is one of a series of individual studies that comprise the SURE programme, evaluated the use of OW semaglutide in a real-world patient population with type 2 diabetes (T2D) in the UK. METHODS In this prospective, observational study, adults (≥ 18 years) with ≥ 1 documented glycated haemoglobin (HbA1c) value ≤ 12 weeks before semaglutide initiation were enrolled. The primary endpoint was change in HbA1c from baseline to end of study (EOS; ~ 30 weeks, although due to the COVID-19 pandemic, visits up to week 52 were permitted). Secondary endpoints included change in body weight, waist circumference and patient-reported outcomes (PROs). Physicians were to report all episodes of documented or severe hypoglycaemia, fatal events, serious adverse drug reactions, pregnancies and adverse events (AEs) in foetuses/newborn infants; other AEs during the study period could be reported on a voluntary basis. RESULT The estimated mean change in HbA1c from baseline to EOS was - 16.3 mmol/mol [95% confidence interval (CI): - 18.22, - 14.37] (- 1.5%-points [95% CI - 1.67, - 1.31]; p < 0.0001) among the 171 enrolled patients who completed the study on treatment. Mean body weight change was - 5.8 kg (95% CI - 6.75, - 4.94; p < 0.0001). Sensitivity analyses showed similar results. Improvements were also observed in other secondary endpoints, including PROs. No new safety concerns were identified with semaglutide treatment. CONCLUSION Patients receiving OW semaglutide experienced statistically significant and clinically relevant reductions from baseline in HbA1c and body weight. These results are in line with those of the SUSTAIN RCTs and support the use of OW semaglutide in routine clinical practice in adults with T2D in the UK.

Abstract
AIM To assess and compare the persistence with drug therapy between patients treated with glucagon-like peptide-1 receptor agonists (GLP1-RA) and sodium-glucose cotransporter-2 inhibitors (SGLT2-I) therapy. METHODS The 126,493 residents of the Lombardy Region (Italy) aged ≥ 40 years newly treated with metformin during 2007-2015 were followed until 2017 to identify those who started therapy with GLP1-RA or SGLT2-I. To make GLP1-RA and SGLT2-I users more comparable, a 1:1 matched cohort design was adopted. Matching variables were sex, age, and adherence to the first-line therapy with metformin. Log-binomial regression models were fitted to estimate the propensity to 1-year treatment persistence in relation to the therapeutic strategy. RESULTS The final matched cohort was composed by 1,276 GLP1-RA─SGLT2-I pairs. About 24% and 29% of cohort members respectively on GLP1-RA and SGLT2-I discontinued the drug treatment. Compared with patients starting SGLT2-I, those on GLP1-RA had 15% (95% confidence interval, 3-25%) lower risk of discontinuation of the treatments of interest and 45% (28-57%) lower risk of discontinuing any antidiabetic drug therapy. Persistence was better among GLP1-RA users who received a once-weekly administration. CONCLUSIONS In a real-life setting, patients who were prescribed a GLP1-RA exhibited more frequently better persistence to treatment than those prescribed a SGLT2-I therapy.

Abstract
BACKGROUND While use of glucagon-like peptide-1 (GLP-1) agonists and sodium-glucose cotransporter-2 (SGLT-2) inhibitors reduces the risk of atherosclerotic cardiovascular disease outcomes and lowers glycosylated haemoglobin (A1C), evidence on patient characteristics associated with clinically relevant A1C reduction is lacking. OBJECTIVE The objective of this retrospective cohort study was to identify patient characteristics associated with A1C reduction with initial GLP-1 or SGLT-2 use. METHODS Patients with type 2 diabetes and a baseline A1C ≥7% who were dispensed a GLP-1 or SGLT-2 between 01/01/10 and 12/31/17 were included. Patients were categorized as having a ≥1% or <1% A1C reduction during the 90-365 days after GLP-1/SGLT-2 initiation. Patient characteristics were collected during the 180 days prior to initiation. Multivariable logistic and linear regression modelling was performed to identify characteristics associated with a ≥1% A1C reduction and absolute change in A1C, respectively. RESULTS Five hundred and seventy-two patients were included with 261 (46%) and 311 (54%) having and not having an ≥1% A1C reduction. Patients were primarily middle-aged, female, white, non-Hispanic and had a high burden of chronic disease. Characteristics associated with a ≥1% A1C reduction included: GLP-1/SGLT-2 persistence, congestive heart failure comorbidity, phentermine dispensing, care management team (CMT) enrollee and higher baseline A1C. Characteristics associated with absolute A1C reduction included: age, baseline A1C, CMT enrollee, GLP-1/SGLT-2 persistence and a phentermine dispensing. CONCLUSIONS The results of this study provide practitioners with guidance on the patients who are most likely to have a clinically relevant A1C reduction with GLP-1 or SGLT-2 use.

Abstract
INTRODUCTION This study aimed to describe utilization patterns, persistence, resource utilization and costs in patients with type 2 diabetes mellitus initiating treatment with glucagon-like peptide 1 receptor agonists in routine clinical practice in Spain. METHODS This retrospective study of medical records in the Big-Pac database identified adults starting treatment with once-weekly (QW) dulaglutide, exenatide-QW or once-daily liraglutide between 1 November 2015 and 30 June 2017. Patients were followed for up to 18 months from treatment initiation. Data on clinical characteristics of patients, treatment patterns, average daily dose and costs were obtained for the three cohorts. Persistence over the 18-month period was evaluated using Kaplan-Meier curves. All analyses were descriptive. RESULTS A total of 1402 patients were included in this study (dulaglutide [n = 492], exenatide-QW [n = 438] or liraglutide [n = 472]); 52.8% were men, and the mean (SD) age was 62 (11) years, glycated haemoglobin (HbA1c) was 8.1% (1.2) and body mass index was 35.5 (3.2) kg/m2 at treatment initiation. Persistence at 18 months was 59.1% (95% confidence interval [CI] 54.8-63.4) for dulaglutide, 45.7% (95% CI 41.0-50.4) for exenatide-QW and 46.6% (95% CI 42.1-51.1) for liraglutide. The average (SD) dose was 1.2 (0.4) mg/week for dulaglutide, 1.9 (0.3) mg/week for exenatide-QW and 1.1 (0.3) mg/day for liraglutide. The average reduction in HbA1c levels at 1 year was - 0.68% for patients who initiated dulaglutide, - 0.54% for patients who initiated exenatide-QW and - 0.50% for patients who initiated liraglutide. The mean (SD) total annual health care costs were €4072 (1946) for dulaglutide, €4418 (2382) for exenatide-QW and €4382 (2389) for liraglutide. CONCLUSION Results suggest that patients who started treatment with dulaglutide had higher persistence over 18 months, presented lower HbA1c levels at 12 months and incurred lower annual total healthcare costs than patients who initiated exenatide-QW or liraglutide.

Abstract
AIM To compare treatment persistence in patients with type 2 diabetes initiating the glucagon-like peptide-1 receptor agonists (GLP-1 RAs) dulaglutide, exenatide once-weekly (QW), liraglutide or lixisenatide in routine clinical practice in Sweden and assess clinical outcomes. MATERIALS AND METHODS We performed a retrospective study using data from several nationwide Swedish health registries, including the National Diabetes Register and other mandatory and population-based registries. Individual level data were collected from 17 361 patients who initiated GLP-1 RA treatment from 23 May 2015 to 15 October 2017, up to 2.5 years postindex (treatment start date). Treatment persistence and modification, predictors of discontinuation, HbA1c and body weight were recorded. Non-persistence was defined as a treatment gap of more than 45 days. Treatment modification included switching and augmentation. Confounding was addressed through the use of propensity scores. RESULTS Treatment persistence was higher and treatment modifications were lower in patients initiating dulaglutide compared with those on exenatide QW, liraglutide and lixisenatide. Patients who remained on the same treatment for 1-year postindex experienced greater HbA1c reductions and a steadier decrease in body weight. CONCLUSIONS Our study suggests that in clinical practice in Sweden there is a greater persistence of treatment among patients initiating dulaglutide compared with those on exenatide QW, liraglutide and lixisenatide. Persistence with the index GLP-1 RA was closely correlated with positive clinical outcomes and thus should be considered a critical factor of patient-centric treatment in Sweden.

Abstract
OBJECTIVES To evaluate the efficacy and safety of the glucagon-like peptide-1 (GLP-1) receptor agonist (RA) oral semaglutide in the treatment of type 2 diabetes mellitus (T2DM) patients. METHODS Randomized controlled trials comparing oral semaglutide with placebo or other antihyperglycemic agents in T2DM patients were identified by searching PubMed, Embase, Cochrane Library and ClinicalTrials.gov. Risk ratios and mean differences with 95% confidence intervals were used to synthesize the results. RESULTS Ten relevant studies involving 8,536 patients were finally included. Compared with placebo, oral semaglutide significantly reduced hemoglobin A1c (HbA1c), body weight, fasting plasma glucose, self-measured plasma glucose (SMPG), serious adverse events and all-cause death and significantly increased the number of participants who achieved HbA1c < 7.0%. Compared with active comparators, oral semaglutide significantly reduced the level of HbA1c, body weight, and SMPG and significantly increased the number of participants who achieved HbA1c < 7.0%. Compared with placebo or active comparators, oral semaglutide did not increase the incidence of adverse events, hypoglycemia (severe or blood glucose-confirmed symptomatic), myocardial infarction, heart failure requiring hospitalization, stroke or acute pancreatitis but did increase the incidence of nausea, diarrhea and vomiting. CONCLUSIONS Oral semaglutide has favorable efficacy and safety in the treatment of T2DM patients. Oral semaglutide may be superior to liraglutide, dulaglutide, empagliflozin and sitagliptin for T2DM patients who have obesity or poor adherence to injectable GLP-1 RAs.

Abstract
Background The adherence of diabetic patients to their medication regimen is associated with many psychosocial factors that are still unknown. Therefore, the present study aims to identify the psychosocial barriers to medication adherence of patients with type2 diabetes (T2D). Methodology This descriptive qualitative study was done in Isfahan, Iran by conducting in-depth unstructured interviews with 23 purposively selected patients with T2D and 10 healthcare providers (HCPs). The participants were interviewed face-to-face between November 2017 and June 2018 at the patient’s home, a Health Care Center, or at the diabetes clinic. Data analysis was performed using MAXQDA-10 software and the conventional content analysis. Results The analysis of the data led to six categories of perceived psychosocial barriers: 1) fear, concern and distress, 2) exhaustion and burnout, 3) the children’s issues being the priority, 4) poor financial support, 5) communication challenges, and 6) poor work conditions. Conclusions This study identified some of the psychosocial barriers to medication adherence of patients with T2D, which will be of great help to researchers and HCPs in designing and implementing effective interventions to overcome these barriers and change patient self-care behaviors and increase their medication adherence.

Abstract
AIM To compare 6-month adherence, persistence and treatment patterns among patients initiating once-weekly glucagon-like peptide-1 receptor agonists (GLP-1RAs), dulaglutide versus semaglutide, and dulaglutide versus exenatide BCise, using claims from the HealthCore Integrated Research Database. MATERIALS AND METHODS Patients aged ≥18 years, with type 2 diabetes, ≥1 claim for dulaglutide, semaglutide or exenatide BCise during the index period February 2018 to December 2018 (index date = earliest GLP-1RA fill date), no claim for GLP-1RAs in the 6-month pre-index period, and continuous enrolment 6 months pre- and post-index were included. Dulaglutide users were propensity-matched 1:1 to semaglutide users (3852 pairs) or exenatide BCise users (1879 pairs). The proportions of adherent (proportion of days covered ≥80%) patients were compared using chi-squared tests. Persistence, measured as days to discontinuation, was analysed using a Cox regression model. RESULTS Matched cohorts (dulaglutide:semaglutide and dulagutide:exenatide BCise) were balanced in baseline characteristics and the mean age was 54 and 55 years, respectively, with approximately 51% and 49% women, respectively. At 6 months, significantly more dulaglutide users were adherent than semaglutide (59.7% vs. 42.7%; P <0.0001) or exenatide BCise users (58.1% vs. 40.3%; P <0.0001). Cox regression showed that dulaglutide users were less likely to discontinue therapy than semaglutide (hazard ratio [HR] 0.71, 95% confidence interval [CI] 0.66, 0.76) or exenatide BCise users (HR 0.59, 95% CI 0.53, 0.65; P <0.0001, both). CONCLUSION At 6-month follow-up, a higher proportion of patients initiating dulaglutide were adherent to and persistent with their treatment, compared to matched patients initiating either semaglutide or exenatide BCise.

Abstract
INTRODUCTION Liraglutide is a glucagon-like peptide-1 analogue used to treat type 2 diabetes mellitus (T2DM). To date, limited long-term data (> 2 years) exist comparing real-world diabetes-related effectiveness and costs for liraglutide versus insulin treatment. METHODS This retrospective claims data analysis covered the period from 1 January 2010 to 31 December 2017 and included continuously insured patients with T2DM who initiated insulin or liraglutide and had 3.5 or 5 years' follow-up data, identified using the German AOK PLUS dataset. Propensity score matching (PSM) was used to adjust for patient characteristics. RESULTS After PSM, there were 825 and 436 patients in the liraglutide and insulin groups at 3.5 and 5 years' follow-up, respectively. Baseline characteristics were similar between compared cohorts. The respective change from baseline to follow-up in mean glycated haemoglobin for liraglutide and insulin patients was - 0.88% and - 0.81% (p > 0.100) after 3.5 years and - 1.15%/ - 1.02% (p > 0.100) after 5 years. Mean respective changes in body mass index (kg/m2) were - 1.21/+ 1.14 (p < 0.001) after 3.5 years and - 1.29/+ 1.13 after 5 years (p < 0.001). Liraglutide- versus insulin-treated patients were less likely to have an early T2DM-related hospitalisation (3.5-year hazard ratio [HR]: 0.414 [95% confidence interval (CI) 0.263-0.651]; 5-year HR: 0.448 [95% CI 0.286-0.701]). At 5 years' follow-up, there was no statistically significant difference in total direct costs between treatment groups (cost ratio: 1.069 [95% CI 0.98-1.13]; p > 0.100). CONCLUSION The clinical effectiveness of liraglutide is maintained long term (up to 5 years). Liraglutide treatment is not associated with higher total direct healthcare costs.

Abstract
Oral semaglutide is the first US Food and Drug Administration-approved oral glucagon-like peptide-1 receptor agonist (GLP-1RA) for the treatment of type 2 diabetes (T2D). Prior articles within this supplement reviewed the PIONEER trial program, which demonstrated that oral semaglutide reduced glycated hemoglobin and body weight when given to patients with uncontrolled T2D on various background therapies, and had a safety profile consistent with subcutaneous GLP-1RAs. This article provides guidance on integrating oral semaglutide into clinical practice in primary care. Patient populations with T2D who may gain benefit from oral semaglutide include those with inadequate glycemic control taking one or more oral glucose-lowering medication (e.g. after metformin), patients for whom weight loss would be beneficial, patients at risk of hypoglycemia, those who would historically have been considered for treatment with a subcutaneous GLP-1RA, and those receiving basal insulin who require treatment intensification. Like other GLP-1RAs, oral semaglutide is contraindicated in those with personal/family history of medullary thyroid carcinoma, and in those with multiple endocrine neoplasia syndrome type 2, as noted in a boxed warning in the prescribing information. Oral semaglutide has not been studied in those with a history of pancreatitis, is not recommended in patients with suspected/confirmed pancreatitis, and is not indicated in type 1 diabetes. When initiating oral semaglutide, gradual dose escalation is recommended to minimize the risk of gastrointestinal adverse events. As food and excess liquid reduce oral semaglutide absorption, patients should swallow the tablet with up to 4 fl oz/120 mL of water on an empty stomach upon waking, and should wait at least 30 minutes before eating, drinking, or taking other oral medications. Those managing patients should be aware of the potential impact of these dosing conditions on concomitant medications. When counseling patients, it is important to discuss these administration instructions, realistic therapeutic expectations, and strategies for mitigation of gastrointestinal events. Oral semaglutide provides a new option for add-on to initial T2D therapy (or later in the treatment paradigm), with the potential to enable more patients to benefit from the improvements in glycemic control, reductions in body weight, and low risk of hypoglycemia afforded by GLP-1RAs.

Abstract
OBJECTIVE | To explore the use of premixed insulin, a glucagon-like peptide 1 (GLP-1) receptor agonist, and metformin as combination therapy for type 2 diabetes. DESIGN AND METHODS | All adult patients with type 2 diabetes who had been prescribed premixed insulin and a GLP-1 receptor agonist simultaneously at our outpatient clinic were selected for retrospective review. We reviewed A1C, weight, cumulative daily insulin dose, and adverse events over 12 months. RESULTS | A total of 72 patients received premixed insulin and a GLP-1 receptor agonist, of which 32 met inclusion criteria. The average duration of type 2 diabetes for these patients was 14.2 ± 7.1 years. Mean A1C at baseline was 10.5 ± 2.1%. At 12 months, mean A1C was 8.3 ± 1.9%. The change in mean A1C after 12 months was -2.2% (95% CI -3.433 to -1.014, P <0.0001). At 12 months, the mean cumulative insulin dose was 33.3 units less than before the therapy change (95% CI -57.13 to -9.46, P = 0.0030). Average weight change at 12 months was -2.2 kg (95% CI -27.6 to 37.6, P = NS). After 12 months, 61% of included patients (19 of 31) had an A1C ≤8%. Six additional patients were not included in analysis because they stopped the regimen after <3 months because of adverse events. CONCLUSION | Despite a decreased cumulative daily dose of insulin, patients with historically uncontrolled type 2 diabetes using metformin, premixed insulin, and a GLP-1 receptor agonist in combination experienced improved glycemic control over 12 months. Prospective randomized trials are needed to better assess the potential benefit of this combination therapy.

Abstract
Objective Medication adherence is impacted by regimen complexity. The SIMPLE (Simple basal Insulin titration, Metformin Plus Liraglutide for type 2 diabetes with very Elevated HbA1c) study compared GLP1RA plus basal insulin (GLP1RA+BI) to basal-bolus insulin (BBI) regimen in participants with very uncontrolled type 2 diabetes mellitus (T2DM). This analysis aimed to evaluate medication adherence to GLP1RA+BI compared with BBI, the effect of adherence on clinical and patient-reported outcomes, and baseline predictors of adherence. Research design and methods This was an analysis of the SIMPLE study based on prespecified outcome. The study took place in pragmatic, real-world setting. A total of 120 adults with T2DM and HgbA1c≥10% were randomized to detemir plus liraglutide, or detemir plus aspart before each meal; 6-month follow-up. The main outcomes evaluated were: adherence, HgbA1c, weight, quality of life, and hypoglycemia. Adherence rate was calculated for each study medication at each follow-up visit; participants were classified as ≥80% or <80% adherent. Result A higher percentage of participants in the GLP1RA+BI compared with the BBI group had ≥80% adherence to detemir (59.3% vs 35.7%, p=0.02) as well as liraglutide versus aspart (57.4% vs 30.4%, p=0.007). Higher age was predictive of ≥80% adherence (OR per 5-year increment=1.48, 95% CI 1.09 to 2.0, p=0.01). Higher adherence led to greater improvement in HbA1c and weight in both groups. Treatment with GLP1RA+BI compared with BBI led to greater improvement in HbA1c, weight, and quality of life and lower risk of hypoglycemia even after adjusting for the difference in adherence between groups. Conclusions Adherence was higher with the simplified regimen of GLP1RA+BI compared with BBI. Greater adherence to the simpler regimen amplified the treatment effect on HbA1c, weight, quality of life, and risk of hypoglycemia, yet statistically significant greater benefits were noted even when adjusted for adherence. Trial registration number NCT01966978.

Abstract
BACKGROUND Persistence with multiple daily insulin injections (MDI) may be challenging for patients with type 2 diabetes (T2DM). However, limited information is available regarding the effect of persistence with MDI on outcomes. OBJECTIVE To evaluate persistence with basal and bolus insulin therapy and assess its relationship with clinical and economic outcomes in a real-world setting. METHODS This retrospective matched cohort study used 2012-2015 data from multiple U.S. commercial health plans (IBM MarketScan). Patients with T2DM aged 18-64 years with ≥ 2 basal and ≥ 2 bolus insulin claims during a 12-month period were eligible for inclusion if they had 18 months of continuous health plan enrollment (6-month baseline and 12-month post-index). Persistence during 12 months post-index was defined using 2 methods: (a) method 1, ≤ 90-day gaps in both basal and bolus insulin claims and (b) method 2, ≥ 1 basal and ≥ 1 bolus insulin claim every quarter (every 90 days) for 4 consecutive quarters after index bolus claim. Propensity score matching was used to match persistent and nonpersistent method 2 cohorts. Mean per-patient all-cause and diabetes-related medical costs (2015 U.S. dollars, excluding outpatient drugs) and health care resource use (HCRU) were calculated. For patients with hemoglobin A1c (A1c) values during baseline and post-index months 10-12, treatment success was defined as (a) A1c decrease from baseline of ≥ 1% and/or (b) baseline A1c ≥ 7% with post-index A1c < 7%. Baseline characteristics of matched cohorts were compared using standardized mean differences (SMDs). Outcome variables were compared using t-tests, chi-square tests, and generalized linear models. RESULTS Characteristics of 12,882 eligible patients and 12-month persistence rates were similar as defined by method 1 (22.4%) and method 2 (21.1%). After matching, the method 2 cohorts included 2,723 and 8,169 persistent and nonpersistent patients, respectively, with well-balanced baseline characteristics (mean age 53 years; 58% men; all SMDs < 0.1). All-cause annual medical costs were lower for the persistent cohort (mean $13,499 vs. $17,362; P < 0.0001), as were annual diabetes-related costs (mean $6,392 vs. $8,376; P < 0.0001). In persistent versus nonpersistent cohorts, 11% versus 15% of patients, respectively, experienced ≥ 1 hospitalization; 21% versus 24%, respectively, had ≥ 1 ED visit; 9% versus 12%, respectively, experienced ≥ 1 diabetes-related hospitalization; and 13% versus 15%, respectively, had ≥ 1 diabetes-related ED visit (P ≤ 0.005 for all). Mean baseline A1c was similar in persistent and nonpersistent cohorts (9.7% vs. 9.6%, respectively; P = 0.63). Persistence with MDI was associated with greater mean reduction in A1c (-1.3% vs. -0.8%, respectively; P = 0.006) and greater percentages of patients achieving treatment success (55% vs. 39%, respectively, for nonpersistent; P = 0.009). CONCLUSIONS Poor persistence with basal-bolus insulin therapy over 12 months of follow-up was prevalent and was associated with greater medical costs, greater HCRU, and poorer glycemic control than for patients who were persistent. Interventions are needed to improve persistence with insulin therapy and aid patients with T2DM to achieve glycemic control.

Abstract
INTRODUCTION This study aimed to demonstrate the beneficial effect of lixisenatide as add-on therapy to oral antidiabetics (OADs) in type 2 diabetes mellitus (T2DM) patients in routine clinical practice in Bulgaria. METHODS This was a prospective, observational, multicentre study evaluating the real-life effectiveness and safety of 24-week treatment with lixisenatide in previously uncontrolled T2DM patients on combination therapy with metformin and sulfonylurea on highest tolerable doses. RESULTS A total of 262 patients were included in the study. The mean (± SD) age in the cohort was 56.2 ± 9.1 years. The mean duration of diabetes was 7.3 ± 6.0 years. The mean body mass index (BMI) was 39.7 ± 4.7 kg/m2. The mean glycated haemoglobin (HbA1c) at baseline was 8.8 ± 1.1%. The mean fasting plasma glucose (FPG) and postprandial plasma glucose (PPG) at baseline were 10.5 ± 3.1 mmol/L and 12.1 ± 3.4 mmol/L respectively. The proportion of patients achieving HbA1c < 7% at study end was 39.0% (95% CI 32.9-45.3). The proportion of patients reaching their individual HbA1c target was 49.0% (95% CI 42.6-55.4). The mean change in HbA1c from baseline was - 1.3 ± 1.2%. The mean change in FPG was - 2.4 ± 3.0 mmol/L and the mean change in PPG was - 3.2 ± 3.6 mmol/L. The mean body weight change from baseline was - 7.2 ± 5.5 kg. The mean BMI change was - 2.6 ± 1.9 kg/m2. The hypoglycaemia incidence was low: 6.1% for all hypoglycaemic events, 3.8% for symptomatic events and 0.4% for severe events. CONCLUSIONS Lixisenatide as add-on therapy to OADs in a real-life setting led to significant improvements in glycaemic control with low incidence of hypoglycaemia and beneficial weight loss. Lixisenatide was well tolerated with few patients having adverse events or discontinuing therapy. These findings are consistent with lixisenatide's safety and efficacy profile established in randomized controlled trials (RCTs). FUNDING Sanofi Bulgaria.

Abstract
INTRODUCTION The glucagon-like peptide-1 receptor agonist (GLP-1 RA) class is evolving and expanding. This retrospective database study evaluated recent real-world treatment and dosing patterns of patients with type 2 diabetes (T2D) initiating GLP-1 RAs in Belgium (BE), France (FR), Germany (DE), Italy (IT), the Netherlands (NL), and Canada (CA). METHODS Adult T2D patients initiating GLP-1 RA therapy (dulaglutide [DULA], exenatide twice daily [exBID], exenatide once weekly [exQW], liraglutide [LIRA], or lixisenatide [LIXI]) from 2015 to 2016 were identified using the IQVIA (IQVIA, Durham, NC, and Danbury, CT, USA) Real-World Data Adjudicated Pharmacy Claims. The therapy initiation date was termed the 'index date.' Eligible patients had ≥ 180 days pre-index and ≥ 360 days post-index. Persistence (until discontinuation or switch) was evaluated over the variable follow-up using Kaplan-Meier (KM) survival analysis. Average daily dose (ADD) was calculated until discontinuation or switch. RESULTS A total of 34,649 DULA, 3616 exBID, 11,138 exQW, 48,317 LIRA, and 2,204 LIXI patients were included in the analysis (34.9-63.2% female; median age range 53-62 years; median follow-up 16-30 months). Proportion persistent at 1-year post-index was 36.8-67.2% for DULA, 5.9-44.4% for exBID, 24.7-44.2% for exQW, 22.2-57.5% for LIRA, and 15.5-40.0% for LIXI. Median time persistent (days) was 245-381 for DULA, 62-243 for exBID, 121-319 for exQW, 103-507 for LIRA, and 99-203 for LIXI. Mean ADD was 13.21-20.43 µg for exBID, 1.44-1.68 mg for LIRA, and 19.88-20.54 µg for LIXI. Mean average weekly dose (AWD) ranged from 2.03 to 2.14 mg for exQW. Mean AWD for DULA was 1.25 mg in Canada and ranged from 1.43 to 1.53 mg in the other countries. CONCLUSION Across six countries, persistence was highest among DULA patients and generally lowest among exBID patients. ADD/AWD for all GLP-1 RAs was in line with the recommended label. Longer-term data would be useful to obtain a better understanding of GLP-1 RA treatment patterns over time. FUNDING Eli Lilly and Company, Indianapolis, IN, USA.

Abstract
INTRODUCTION Improving real-world medication adherence to injectable antihyperglycemics in type 2 diabetes mellitus (T2DM) is a clinical challenge. Quantification of the level of adherence required to achieve a minimal clinically important difference (MCID) in glycemic control would assist in meeting this goal. The study objective was to review the literature regarding the relationships of medication adherence and persistence with health outcomes in adult T2DM patients using injectable antihyperglycemics. METHODS Systematic searches were conducted using electronic databases to identify publications over the last decade. Publications were screened against established eligibility criteria. Study data were extracted, evaluated, and used to identify strengths, limitations, and gaps in current evidence. RESULTS Eligibility criteria were met by 38 studies, and this report analyzed 34 studies related to glycemic control (n = 25), healthcare resource use (n = 9), and healthcare costs (n = 14). Eight of these studies examined adherence to glucagon-like peptide-1 receptor agonists (GLP-1 RA), including 1 study regarding adherence to GLP-1 RA or to insulin, and 1 study investigating a GLP-1 RA/insulin combination; the remaining studies involved insulin. Studies used a broad range of measures to classify adherence and persistence, and most measures were unable to reliably evaluate the complexities of patient behavior over time. Better adherence to injectable antihyperglycemic medications was generally found to be associated with improved glycemic control, although no studies attempted to identify a MCID. Although higher diabetes-related pharmacy and total healthcare costs were reported for adherent or persistent patients, these patients tended to have lower diabetes-related and all-cause medical costs. CONCLUSION Results of this review confirmed the effectiveness of injectable antihyperglycemic medications for glycemic control, suggesting that there are clinical and financial consequences to nonadherence. Although attempts were made to quantify the effects of nonadherence, the interpretation of study results was limited by the lack of a MCID and inadequate study design.

Abstract
BACKGROUND & AIMS We compared the effects of weight loss induced with the glucagon-like peptide-1 agonist liraglutide, with that of lifestyle modification, followed by weight maintenance after discontinuing intervention, in obese adults with non-alcoholic fatty liver disease (NAFLD). METHODS Thirty obese (mean age 40.7 ± 9.1 years, BMI 33.2 ± 3.6 kg/m2 , 90% male) adults with NAFLD defined as liver fat fraction (LFF) > 5% on magnetic resonance imaging without other causes of hepatic steatosis were randomized to a supervised programme of energy restriction plus moderate-intensity exercise to induce ≥ 5% weight loss (DE group, n = 15), or liraglutide 3 mg daily (LI group, n = 15) for 26 weeks, followed by 26 weeks with only advice to prevent weight regain. RESULTS Diet and exercise and LI groups had significant (P < 0.01) and similar reductions in weight (-3.5 ± 3.3 vs -3.0 ± 2.2 kg), LFF (-8.1 ± 13.2 vs -7.0 ± 7.1%), serum alanine aminotransferase (-39 ± 35 vs -26 ± 33 U/L) and caspase-cleaved cytokeratin-18 (cCK-18) (-206 ± 252 vs -130 ± 158 U/L) at 26 weeks. At 52 weeks, the LI group significantly (P < 0.05) regained weight (1.8 ± 2.1 kg), LFF (4.0 ± 5.3%) and cCK-18 (72 ± 126 U/L), whereas these were unchanged in the DE group. CONCLUSIONS Liraglutide was effective for decreasing weight, hepatic steatosis and hepatocellular apoptosis in obese adults with NAFLD, but benefits were not sustained after discontinuation, in contrast with lifestyle modification. Continuing the exercise learned in the structured programme contributed to the maintenance of liver fat reduction.

Abstract
INTRODUCTION In both randomized controlled trials and real-world studies, liraglutide has demonstrated glycemic and body weight benefits in patients with type 2 diabetes. However, persistence with diabetes medication can be challenging. This study compared glycated hemoglobin (HbA1c) and other outcomes in patients with type 2 diabetes who continued treatment with liraglutide for over 12 months with those who discontinued treatment earlier, in a real-life setting. METHODS This is a retrospective study of adult patients with type 2 diabetes from Maccabi Healthcare Services in Israel, who initiated treatment with liraglutide from 2010 to 2015. Mean HbA1c and body weight change from initiation to after 24 months was compared between patients who received liraglutide for at least 12 months ("continuers") and those who discontinued within the first year ("discontinuers"). Adjustment for HbA1c, body weight, and other potentially confounding factors was performed using 1:1 propensity score matching. RESULTS The 3580 patients comprised 2695 continuers and 885 discontinuers; 882 patients per group were matched. A significant (p < 0.001) reduction in HbA1c (- 0.80% vs - 0.32%) was seen in continuers compared with discontinuers, despite higher insulin usage (70.2% vs 59.0%; p < 0.001), and a higher proportion of patients using ≥ 3 oral glucose-lowering drugs (20.6% vs 6.2%; p < 0.001) at 24 months among discontinuers. Mean body weight reduction was greater in continuers than discontinuers (3.57 vs 1.25 kg; p < 0.001). CONCLUSION In a real-world setting, persistent use of liraglutide was associated with good glycemic and body weight control. FUNDING Novo Nordisk Health Care AG.

Abstract
AIMS To evaluate adherence, persistence, glycaemic control and costs at 12-month follow-up for patients initiating dulaglutide versus liraglutide or exenatide once weekly. MATERIALS AND METHODS The present retrospective observational claims study included patients with type 2 diabetes (T2D) and ≥ 1 pharmacy claim for dulaglutide, liraglutide or exenatide once weekly from the HealthCore Integrated Research Database. Adherence was defined as proportion of days covered ≥80%, and persistence was measured by time to discontinuation of index therapy. Change from baseline in glycated haemoglobin (HbA1c) concentration was assessed in a subset with pre- and post-index HbA1c results. Propensity scores were used to match the cohorts. RESULTS The baseline characteristics were balanced for the matched cohorts, dulaglutide versus liraglutide (n = 2471) and dulaglutide versus exenatide once weekly (n = 1891). Among those initiating dulaglutide there was a significantly higher proportion of adherent patients compared with the groups initiating liraglutide (51.2% vs. 38.2%; P < 0.001) and exenatide once weekly (50.7% vs. 31.9%; P < 0.001). At 12 months, 55% of patients in the dulaglutide group versus 43.8% in the liraglutide group (P < 0.001), and 54.9% in the dulaglutide versus 34.4% in the exenatide once-weekly group (P < 0.001) were persistent. The dulaglutide group had a significantly greater reduction in HbA1c than the liraglutide group (-34.24 vs. -31.94 mmol/mol; P = 0.032), and a greater, but nonsignificant, reduction in HbA1c than the exenatide once-weekly group (-34.46 vs. -31.94 mmol/mol; P = 0.056). The diabetes-related total costs were not significantly different between the dulaglutide and the liraglutide group ($16,174 vs. $16,694; P = 0.184), and were significantly higher for dulaglutide than for exenatide once weekly ($15,768 vs. $14,615; P = 0.005). CONCLUSIONS Adherence and persistence are important considerations in patient-centric treatment selection for patients with T2D. Higher adherence and persistence for dulaglutide compared with liraglutide or exenatide once weekly are relevant criteria when choosing glucagon-like peptide-1 receptor agonist treatment for patients with T2D.

Abstract
Treatment persistence (continuing to take medication for the prescribed period) and treatment adherence (complying with the prescription in terms of drug schedules and dosage) are both important when treating chronic diseases such as type 2 diabetes (T2D). They can be indicators of patient satisfaction with treatment. In T2D, the achievement of optimal outcomes requires both persistence with and adherence to prescribed therapy. Poor persistence with and adherence to T2D medication can have profound consequences for the patient, including non-achievement of glycaemic goals and an increased risk of long-term complications and mortality. Therefore, poor treatment persistence and adherence may also have economic consequences, including increased healthcare resource utilization and healthcare costs. Treatment persistence and adherence are affected by several factors, including the mode of administration, administration frequency/regimen complexity, and patient expectations. The aims of this review are as follows: to provide an overview of persistence with and adherence to different antidiabetes therapies for patients with T2D in the real-world setting; examine factors contributing to poor treatment persistence and adherence; and assess available data on the impact of poor treatment persistence and/or adherence on clinical and economic outcomes. Numerous potential targets for improving treatment persistence and/or adherence are identified, including developing less complex treatment regimens with lower pill burdens or less frequent injections, improving the convenience of drug-delivery systems, such as the use of insulin pen devices rather than the conventional vial and syringe, and developing therapies with an improved safety profile to alleviate patient fears of adverse effects, such as weight gain and risk of hypoglycaemia.Funding: Sanofi.

Abstract
BACKGROUND Management of elderly patients with type 2 diabetes mellitus (T2DM) is complex due to their age-related conditions. Several clinical guidelines provide specific recommendations for management of these patients but little is known about their implementation in clinical practice. OBJECTIVE To describe physician and community pharmacist perceptions and routine clinical practice in the management of elderly T2DM patients. METHODS Cross-sectional study. RESULTS A total of 993 physicians and 999 community pharmacists completed the questionnaire. More physicians than pharmacists agreed on the need to establish more flexible HbA1c targets for elderly (79.4% vs. 30.6%; p < 0.001) and frail (92.6% vs. 31.4%; p < 0.001) patients than for the general diabetic population. HbA1c targets < 7.5% for elderly patients and < 8.5% for frail patients (as recommended by the principle guidelines) were set by 38.9% and 28.7% of physicians, respectively. Furthermore, 62.8% of physicians stated they follow guideline recommendations but, based on their prescription decisions for hypothetical patients, less than 50% were aligned with them. In addition, 73.1% of physicians monitor treatment adherence, mainly by using dispensing control (59.1%). Specific nutritional approaches for elderly patients are provided by 62.9% of physicians and 56.0% of pharmacists, whilst 57.4% and 21.7%, respectively, deliver specific physical exercise programs. CONCLUSIONS Low adherence to guideline recommendations (i.e. setting more stringent HbA1c targets or delaying treatment intensification) may lead to suboptimal glycaemic control in elderly patients. The standardization of processes, extensive monitoring of patient treatment adherence and providing advice regarding specific personal lifestyle habits may improve the management of elderly T2DM patients.

Abstract
AIMS To evaluate in a real-world setting the effectiveness and tolerability of available GLP-1 RA drugs in patients with type 2 diabetes after a prolonged follow-up. MATERIALS AND METHODS Observational, retrospective, single-centre study in patients starting GLP-1 RA therapy. Change in HbA1c, fasting plasma glucose (FPG) and body mass index (BMI) along with gastrointestinal (GI) adverse events and withdrawal from GLP-1 RA therapy were evaluated. Lack of efficacy of GLP-1 RA therapy according to prespecified goals was also measured. RESULTS A total of 735 patients were included, mean age 59.7 years, duration of diabetes 9.01 years, HbA1c 8.18% and BMI 38.56 kg/m2. Average follow-up was 18.97 months (range 4.2-39.09). All HbA1c (0.93%; P < 0.01), FPG (24 mg/dL; P < 0.01) and BMI (1.55 kg/m2; P < 0.05) were significantly reduced from baseline and maintained throughout follow-up, regardless of prescribed GLP-1 RA. GI adverse events were present in 13.81% of patients at first follow-up visit, 37.07% of patients discontinued GLP-1 RA treatment, and 38.63% did not meet efficacy goals. CONCLUSIONS In a real-world setting, GLP-1 RA therapy is largely prescribed in severely obese patients with a long-standing and poorly controlled diabetes. All prescribed GLP-1 RAs significantly decreased HbA1c, FPG and BMI. GI adverse events affected a low proportion of patients. Inversely, a high proportion of patients did not meet efficacy goals and/or discontinued GLP-1 RA treatment. Baseline characteristics of patients and lack of adherence may represent important issues underlying differences in effectiveness in real-world studies versus randomized trials.

Abstract
INTRODUCTION Diabetes mellitus is a metabolic disease characterized by high glycemic levels for long periods. This disease has a high prevalence in the world population, being currently observed an increase in its incidence. This fact is mainly due to the sedentary lifestyle and hypercaloric diets. Non-pharmacological interventions for glycemic control include exercise, which promotes changes in skeletal muscle and adipocytes. Thus, increased glucose uptake by skeletal muscle and decreased insulin resistance through modulating adipocytes are the main factors that improve glycemic control against diabetes. CONCLUSION It was sought to elucidate mechanisms involved in the improvement of glycemic control in diabetics in front of the exercise.

Abstract
This post hoc analysis of gastrointestinal (GI) adverse events (AEs) from the phase 3 LixiLan-L (NCT02058160) and LixiLan-O (NCT02058147) trials aimed to determine the frequency and timing of nausea, vomiting, and diarrhoea for iGlarLixi, a titratable, fixed-ratio combination of insulin glargine 100 units/mL (iGlar) and lixisenatide, versus iGlar alone or iGlar and lixisenatide alone, in patients with type 2 diabetes uncontrolled with oral antidiabetes drugs (OADs) or basal insulin ± OADs. In iGlarLixi-treated patients, the rate of GI AEs during the initial weeks of treatment was lower versus patients treated with lixisenatide alone (9.6% and 11.7% of iGlarLixi-treated patients in LixiLan-L and LixiLan-O, respectively, vs. 27.5% of lixisenatide-treated patients in LixiLan-O). Beyond day 60, these rates were generally low and similar to those of lixisenatide. These lower rates are likely due to the gradual titration of lixisenatide in iGlarLixi. Median durations of intermittent GI AEs in the iGlarLixi arms were 6.0, 2.0 and 2.5 days (LixiLan-L), and 5.0, 1.0 and 3.5 days (LixiLan-O), respectively. iGlarLixi-associated GI AEs were transient, mostly mild or moderate in severity, and occurred mainly during initial titration.

Abstract
AIMS To compare real-world antidiabetic treatment outcomes over 12 months in obese people with type 2 diabetes mellitus (T2DM) who previously received oral antidiabetic therapy and then initiated a first injectable therapy with liraglutide or basal insulin. PATIENTS AND METHODS This was a retrospective, propensity score-matched, longitudinal cohort study using real-world data (January 2010 to December 2015) from the Dutch PHARMO Database Network. Adult obese (body mass index [BMI] ≥35 kg/m2 ) patients with T2DM with ≥2 dispensing dates for liraglutide or basal insulin supported oral therapy (BOT) were selected. The primary endpoint was the change in glycated haemoglobin (HbA1c) from baseline during 12 months of follow-up. The secondary endpoints were the changes in weight, BMI and cardiovascular risk factors from baseline. Clinical data were analysed using descriptive statistics and compared using mixed models for repeated measures. RESULTS Obese patients with T2DM (N = 1157) in each treatment group were matched (liraglutide cohort, n = 544; BOT cohort, n = 613). From 3 months onwards, glycaemic control improved in both cohorts but improved significantly more with liraglutide than with BOT (12 months: -12.2 mmol/mol vs -8.8 mmol/mol; P = .0053). In addition, weight and BMI were significantly lower for treatments with liraglutide vs BOT (12 months: -6.0 kg vs -1.6 kg and - 2.1 kg/m2 vs -0.5 kg/m2 , respectively; P < .0001 for both). No significant differences were seen in changes in cardiovascular risk factors. CONCLUSIONS The results of this real-world study in matched obese patients with T2DM showed that liraglutide was more effective than BOT for HbA1c control and weight/BMI reductions. Patients were more likely to maintain glycaemic control over time after initiating liraglutide than after initiating BOT.

Abstract
OBJECTIVES To assess glycemic effectiveness, adherence and persistence within 6 months of treatment initiation with dulaglutide, a once weekly GLP-1 receptor agonist, in a US real-world setting. METHODS This retrospective claims analysis included adults (≥18 years) with T2DM from the HealthCore Integrated Research Database, who had HbA1c laboratory results around initiation and within 6 months after initiation. Glycemic control was assessed by change in HbA1c from pre-initiation to post-initiation. Patients were considered adherent if their proportion of days covered (PDC) was ≥0.80; persistence was measured as days of continuous therapy from initiation to 6 months after initiation with no gaps >45 days between fills. RESULTS Of the 308 analyzed patients, the majority (n = 188; 61%) were adherent to dulaglutide (mean PDC 0.76; SD 0.26), with 115 patients (37%) discontinuing treatment. Mean persistence was 152 days/5 months. Mean HbA1c decreased from 8.49% (SD 1.70, median 8.20%) at baseline to 7.59% (SD 1.51, median 7.30%) at follow-up, corresponding to a mean HbA1c change of -0.90% (95% confidence interval [CI] -1.08 to -0.73; p < .01; median -0.70%). Patients who were adherent to or persistent with dulaglutide experienced larger reductions (-1.14% and -1.12% respectively), as did those without prior GLP-1 RA use (-1.03%). The proportion of patients with HbA1c <7% increased from 18% to 40%. CONCLUSIONS Dulaglutide was associated with a significant decrease in HbA1c levels 6 months after treatment initiation. Patients who adhered to or persisted with dulaglutide therapy, or were naïve to GLP-1 RA use, experienced greater decreases in HbA1c levels.

Abstract
Adherence to antihyperglycemic medications is often suboptimal in patients with type 2 diabetes, and this can contribute to poor glycemic control, increased hospitalization, and the development of diabetic complications. Reported adherence rates to antihyperglycemics vary widely among studies, and this may be related to differences in methodology for measuring adherence, patient populations, and other factors. Poor adherence may occur regardless of the specific regimen used and whether therapy is oral or injectable, and can be especially common in chronic, asymptomatic conditions, such as type 2 diabetes. More convenient drug-administration regimens and advances in formulations and delivery devices are among strategies shown to improve adherence to antihyperglycemic therapy, especially for injectable therapy. This is exemplified by technological developments made in the drug class of glucagon-like peptide 1-receptor agonists, which are a focus of this narrative review. Dulaglutide, albiglutide, and prolonged-release exenatide have an extended duration of action and can be administered once weekly, whereas such agents as liraglutide require once-daily administration. The convenience of once-weekly versus once-daily administration is associated with better adherence in real-world studies involving this class of agent. Moreover, provision of a user-friendly delivery device has been shown to overcome initial resistance to injectable therapy among patients with type 2 diabetes. This suggests that recent innovations in drug formulation (eg, ready-to-use formulations) and delivery systems (eg, single-dose prefilled pens and hidden, ready-attached needles) may be instrumental in encouraging patient acceptance. For physicians who aim to improve their patients' adherence to antihyperglycemic medications, it is thus important to consider the patient's therapeutic experience (treatment frequency, drug formulation, delivery device). Better adherence, powered by recent technological advances in the delivery of glucagon-like peptide 1-receptor agonists, may thus lead to improved clinical outcomes in type 2 diabetes.

Abstract
INTRODUCTION Real-world evidence on glucagon-like peptide-1 receptor agonist (GLP-1 RAs) usage is emerging in different European countries but is lacking in Italy. This retrospective cohort study aimed to describe the real-world drug utilization patterns in patients initiating GLP-1 RAs for treating T2DM in Italy. METHODS Adults aged ≥ 20 years and with ≥ 1 oral antidiabetic drug (alone or in combination with insulin) other than GLP-1 RAs in the 6 months prior to initiating exenatide twice daily (exBID), exenatide once weekly (exQW), dulaglutide once weekly (DULA), liraglutide once daily (LIRA) or lixisenatide once daily (LIXI) between March and July 2016 were retrospectively identified in the Italian IMS LifeLink™ longitudinal prescriptions database (retail pharmacy data). Patients with ≥ 6-month follow-up (defined as evidence of any prescription activity) were included. Proportions of patients who remained persistent (continued treatment until discontinuation/switch) in the first 6 months and of those who discontinued or switched to a different GLP-1 RA over the entire follow-up were recorded. For each treatment, the average daily/weekly dosage (ADD/AWD) while persistent during the available follow-up was calculated. RESULTS We identified 7319 patients: 92 exBID, 970 exQW, 3368 DULA, 2573 LIRA and 316 LIXI. Across treatments, 89% patients were ≥ 50 years old, 54% were males, and the median follow-up duration ranged between 8.1 and 8.7 months. At 6 months, 35% exBID, 47% exQW, 62% DULA, 50% LIRA and 40% LIXI patients remained persistent. Over the entire follow-up, median persistence days varied from 73 (exBID) to > 300 days (DULA). The mean ± SD ADD/AWD was exBID: 17.7 ± 2.1 µg/day; exQW: 2.1 ± 0.1 mg/week; DULA: 1.5 ± 0.2 mg/week; LIRA: 1.5 ± 0.2 mg/day; LIXI: 21.0 ± 5.5 µg/day. CONCLUSIONS This real-world analysis suggests differences exist in persistence between patients treated with various GLP-1 RAs. Among the investigated treatments, patients prescribed exBID recorded the lowest and those prescribed DULA the highest persistence with therapy. FUNDING Eli Lilly and Co., Indianapolis, IN, USA.

Abstract
OBJECTIVE ITCA 650 is a subdermal osmotic mini-pump that continuously delivers exenatide subcutaneously for 3-6 months. The efficacy, safety, and tolerability of ITCA 650 added to diet and exercise alone or combined with metformin, sulfonylurea, or thiazolidinedione monotherapy or a combination of these drugs was evaluated in poorly controlled patients with type 2 diabetes (T2D) who were ineligible for participation in a placebo-controlled study (FREEDOM-1) because of severe hyperglycemia (HbA1c >10% [86 mmol/mol]). RESEARCH DESIGN AND METHODS This 39-week, open-label, phase 3 trial enrolled patients aged 18-80 years with HbA1c >10% to ≤12% (86-108 mmol/mol) and BMI 25-45 kg/m2. Patients received ITCA 650 20 μg/day for 13 weeks, then 60 μg/day for 26 weeks. The primary end point was change in HbA1c at week 39. RESULTS Sixty patients were enrolled. At baseline, mean HbA1c was 10.8% (94.7 mmol/mol) and mean (± SD) duration of diabetes was 8.6 (± 5.3) years. At week 39, there was a mean reduction in HbA1c of -2.8% (-30.3 mmol/mol; P < 0.001 vs. baseline) and in body weight of -1.2 kg (P = 0.105), and 25% of patients achieved HbA1c <7% (53 mmol/mol). A reduction in HbA1c of ≥1% (≥10.9 mmol/mol) occurred in 90% of patients. The most common adverse events were nausea, vomiting, diarrhea, and headache. Gastrointestinal adverse events were generally transient and subsided over time; only 4 patients (6.7%) discontinued for gastrointestinal events. CONCLUSIONS Treatment with ITCA 650, the first injection-free glucagon-like peptide 1 receptor agonist, resulted in significant improvements in glycemic control in poorly controlled long-standing T2D patients with a high baseline HbA1c >10%.

Abstract
AIMS To evaluate treatment satisfaction in patients with type 2 diabetes (T2D) not adequately controlled by metformin, randomized to ITCA 650 (continuous exenatide in osmotic mini-pump) vs twice-daily exenatide injections (Ex-BID). MATERIALS AND METHODS The Diabetes Medication Satisfaction Tool (DM-SAT) was administered and assessments were made at baseline, Week 8 and Week 20 during a 24-week open-label phase 2 trial. In Stage I (Weeks 1-12), 155 patients, comprising the ITT population, were randomized to 3 groups: ITCA 650 20 μg/day, ITCA 650 40 μg/day and Ex-BID 10 μg BID. In Stage II (Weeks 13-24), ITCA 650 groups were re-randomized to either remain on the Stage I dose or receive a higher dose. Patients treated with Ex-BID were randomized to 40 or 60 μg/day ITCA 650. RESULTS Patients using ITCA 650 reported significant increases in overall treatment satisfaction by Week 8 vs those using Ex-BID (P < .01), despite similar clinical efficacy and overall rates of nausea. During Stage II, further improvement in HbA1c and weight were seen after 3-fold dose escalation of ITCA 650 and treatment satisfaction was maintained. When patients using Ex-BID were switched to ITCA 650, treatment satisfaction increased and reached levels similar to those initially treated with ITCA 650. Neither GI side effects of nausea and/or vomiting, nor the procedure to sub-dermally place ITCA 650, significantly impacted treatment satisfaction scores. CONCLUSION ITCA 650 added to metformin for patients with T2D, and for those who switched to ITCA 650 from Ex-BID, meaningfully improved glucose control and significantly increased overall treatment satisfaction.
