Adherence and persistence among patients with type 2 diabetes initiating dulaglutide compared with semaglutide and exenatide BCise: 6-month follow-up from US real-world data.

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.

Project description: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.

Project description:IntroductionOnce-weekly semaglutide 1 mg is a novel glucagon-like peptide 1 receptor agonist (GLP-1 RA) that, in the SUSTAIN clinical trials, has demonstrated greater reductions in glycated haemoglobin (HbA1c) and body weight than the other GLP-1 RAs exenatide extended-release (ER) 2 mg, dulaglutide 1.5 mg and liraglutide 1.2 mg. The aim of this analysis was to evaluate the relative cost of control of achieving treatment goals in people with type 2 diabetes (T2D) treated with once-weekly semaglutide versus exenatide ER, dulaglutide and liraglutide from a UK perspective.MethodsProportions of patients reaching HbA1c targets (< 7.0% and < 7.5%), weight loss targets (≥ 5% reduction in body weight) and composite endpoints (HbA1c < 7.0% without weight gain or hypoglycaemia; reduction in HbA1c of ≥ 1% and weight loss of ≥ 5%) were obtained from the SUSTAIN clinical trials. Annual per patient treatment costs were based on wholesale acquisition costs from July 2019 in the UK. Cost of control was calculated by plotting relative treatment costs against relative efficacy.ResultsThe annual per patient cost was similar for all GLP-1 RAs. Once-weekly semaglutide was superior to exenatide ER, dulaglutide and liraglutide in bringing patients to HbA1c and weight loss targets, and to composite endpoints. When looking at the composite endpoint of HbA1c < 7.0% without weight gain or hypoglycaemia, exenatide ER, dulaglutide and liraglutide were 50.0%, 21.6% and 51.3% less efficacious in achieving this, respectively, than once-weekly semaglutide. Consequently, the efficacy-to-cost ratios for once-weekly semaglutide were superior to all comparators in bringing patients to all endpoints.ConclusionsThe present study showed that once-weekly semaglutide offers superior cost of control versus exenatide ER, dulaglutide and liraglutide in terms of achieving clinically relevant, single and composite endpoints. Once-weekly semaglutide 1 mg would therefore represent good value for money in the UK setting.

Project description:IntroductionThe superior efficacy and safety of semaglutide once-weekly (QW), compared with dulaglutide, liraglutide, or exenatide QW, have been demonstrated in the SUSTAIN trials. This study assessed treatment persistence and adherence to semaglutide QW versus dulaglutide, liraglutide, or exenatide QW in a real-world setting.MethodsThis retrospective, database study used Optum's de-identified Clinformatics® Data Mart Database to identify glucagon-like peptide 1 receptor agonist (GLP-1 RA) treatment-naïve adult patients with type 2 diabetes (T2D) initiating semaglutide QW, dulaglutide, liraglutide, or exenatide QW between January 1, 2018 and April 30, 2019. Persistence (time remaining on treatment) was assessed with Kaplan-Meier survival estimates and Cox proportional hazard models. Adherence was assessed using proportion of days covered (PDC) and proportion of patients with PDC > 80%.ResultsOf 56,715 patients included, 3279 received semaglutide QW, 27,891 dulaglutide, 17,186 liraglutide, and 8359 exenatide QW. Patients initiating semaglutide QW were younger and with lower percentage of Medicare coverage than patients initiating the comparators. Persistence at 360 days was significantly higher for semaglutide QW (67.0%) versus dulaglutide (56.0%), liraglutide (40.4%), and exenatide QW (35.5%); p < 0.001 for all comparisons. Compared with semaglutide QW, the discontinuation rate was significantly higher for dulaglutide (hazard ratio [HR] 1.22; 95% confidence interval [CI] 1.13, 1.32; p < 0.001), liraglutide (HR 1.80; 95% CI 1.66, 1.95; p < 0.001), and exenatide QW (HR 2.12; 95% CI 1.96, 2.30; p < 0.001). Adherence to semaglutide QW versus liraglutide at 360 days and to exenatide QW was 39.1% versus 30.0% [p = 0.07] and 27.7% [p = 0.02], respectively. Adherence to dulaglutide at 360 days was numerically higher than semaglutide QW (43.2% versus 39.1%; p = 0.45) but did not reach statistical significance.ConclusionPersistence with semaglutide QW was significantly greater than comparators, while adherence was comparable or greater. Together with earlier results from double-blind clinical studies, these data support semaglutide QW use for treatment of patients with T2D.

Project description:IntroductionOnce-weekly semaglutide is a novel glucagon-like peptide-1 (GLP-1) analog for the treatment of type 2 diabetes (T2D) that has been associated with greater reductions in glycated hemoglobin (HbA1c) and body weight versus GLP-1 receptor agonists dulaglutide, exenatide extended-release (ER), liraglutide and lixisenatide in the SUSTAIN trial program and a network meta-analysis (NMA). The aim of the present study was to assess the long-term cost-effectiveness of semaglutide versus all available GLP-1 receptor agonists in Denmark, using a clinically orientated treatment approach.MethodsOutcomes were projected over patient lifetimes using the IQVIA CORE Diabetes Model. Baseline characteristics and treatment effects were sourced from the corresponding SUSTAIN trials and the NMA. Patients were assumed to initiate GLP-1 receptor agonist therapy and subsequently treatment-intensify according to clinical treatment guidelines, with addition of basal insulin and switching to basal-bolus insulin occurring when HbA1c exceeded recommended targets. Patients were assumed to receive a GLP-1 receptor agonist plus basal insulin therapy once HbA1c levels reached 7.5% and a basal-bolus insulin regimen once HbA1c exceeded 8.0%. Costs were captured in 2017 Danish kroner (DKK), with future costs and outcomes discounted at 3% per annum.ResultsPrimary analyses indicated that semaglutide 0.5 mg and 1 mg were associated with improvements in quality-adjusted life expectancy of 0.11 and 0.34 quality-adjusted life years, respectively, versus dulaglutide, achieved at cost savings of DKK 289 and DKK 13,416, respectively. Supporting analyses indicated that both doses of semaglutide were either cost-effective or dominant versus exenatide ER, liraglutide 1.2 mg and 1.8 mg and lixisenatide.ConclusionSemaglutide represents a cost-effective alternative to other GLP-1 receptor agonist therapies available in Denmark, demonstrating clinical benefits versus dulaglutide, exenatide ER, liraglutide and lixisenatide for the treatment of patients with T2D.FundingNovo Nordisk A/S.

Project description:Atorvastatin, which has been approved by regulatory agencies for primary- and secondary-prevention patients with dyslipidemia, has historically been the most commonly prescribed statin and is now widely available in generic formulations. Despite widespread statin usage, many patients fail to attain recommended (LDL-C) targets. While several factors impact the successful treatment of dyslipidemia, suboptimal patient adherence is a major limiting factor to medication effectiveness. In this narrative review we sought to investigate patient adherence and persistence with atorvastatin in a real-world setting and to identify barriers to LDL-C goal attainment and therapy outcomes beyond the realm of clinical trials. Moreover, in light of growing generic usage, we carried out targeted literature searches to investigate the impact of generic atorvastatin availability on patient adherence/persistence, and on lipid and efficacy outcomes, compared with branded formulations. Unsurprisingly, real-world data suggest that patient adherence/persistence to atorvastatin is suboptimal, but few studies have attempted to address factors impacting adherence. Data from studies comparing adherence/persistence in patients prescribed branded or generic atorvastatin are limited and show no clear evidence that initiation of a specific preparation of atorvastatin impacts adherence/persistence. Furthermore, results from studies comparing adherence/persistence of patients who switched from the branded to the generic drug are conflicting, although they do suggest that switching may negatively impact adherence over the long term. Additional real-world studies are clearly required to understand potential differences in adherence and persistence between patients initiating treatment with branded versus generic atorvastatin and, moreover, the factors that influence adherence. Targeted education initiatives and additional research are needed to understand and improve patient adherence in a real-world setting.

Project description:IntroductionLong-acting injectable antipsychotic agents have been suggested to improve adherence and patient outcomes in schizophrenia or schizoaffective disorder. The purpose of this study was to assess medication use patterns (i.e., medication adherence, persistence), hospital and emergency department readmissions, and total direct medical costs of Oklahoma Medicaid members with schizophrenia or schizoaffective disorder switching from an oral antipsychotic (OAP) to once-monthly paliperidone palmitate (PP1M) or to another OAP (OAP-switch).MethodsA historical cohort analysis was conducted from 1 January 2016 to 31 December 2020 among adults aged ≥ 18 and ≤ 64 years with schizophrenia or schizoaffective disorder who were previously treated with an OAP. The first claim for PP1M or a new OAP defined the study index date. Members who transitioned from PP1M to 3-month formulation (PP3M) were included (i.e., PP1M/PP3M). Proportion of days covered (PDC), 45-day treatment gaps, 30-day readmissions to hospitals or emergency department, and total direct medical costs were assessed using multivariable, machine-learning least absolute shrinkage, and selection operator (Lasso) regressions controlling for numerous demographic, clinical, mental health, and provider characteristics.ResultsAmong 295 Medicaid members meeting full inclusion criteria, 183 involved PP1M/PP3Ms (44 PP1M cases transitioned to PP3M) and 112 involved an OAP-switch. The multivariable-adjusted odds of readmission were significantly associated with a 45-day treatment gap (p < 0.05) and non-adherence (i.e., PDC < 80%) (p < 0.05). Relative to PP1M/PP3Ms, the multivariable analyses also indicated that OAP-switch was associated with an 18.5% lower PDC, 92.3% higher number of 45-day treatment gaps, and an approximately 90% higher odds of all-cause 30-day readmission (p < 0.05). The adjusted pre- to post-index change in cost was approximately 49% lower for OAP-switches versus PP1M/PP3Ms (p < 0.001), although unadjusted post-index costs did not differ between groups (p = 0.440).ConclusionThis real-world investigation of adult Medicaid members with schizophrenia or schizoaffective disorder observed improved adherence and persistence with fewer readmissions with PP1M/PP3Ms versus OAP-switches.

Project description:ObjectivesThis study examined patient adherence and persistence to oral bisphosphonates for the treatment of osteoporosis in real-world settings.MethodsA systematic review was completed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Medical Literature Analysis and Retrieval System Online (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Allied and Complementary Medicine Database (AMED), Database of Abstracts of Reviews of Effects (DARE), Health Technology Assessment (HTA) and National Health Service Economic Evaluation Database NHS EED) databases were searched for studies published in English language up to April 2018. Prospective and retrospective observational studies that used prescription claim databases or hospital medical records to examine patient adherence and persistence to oral bisphosphonate treatment among adults with osteoporosis were included. The Newcastle-Ottawa quality assessment scale (NOS) was used to assess the quality of included studies.ResultsThe search yielded 540 published studies, of which 89 were deemed relevant and were included in this review. The mean age of patients included within the studies ranged between 53 to 80.8 years, and the follow-up varied from 3 months to 14 years. The mean persistence of oral bisphosphonates for 6 months, 1?year and 2 years ranged from 34.8% to 71.3%, 17.7% to 74.8% and 12.9% to 72.0%, respectively. The mean medication possession ratio ranged from 28.2% to 84.5%, 23% to 50%, 27.2% to 46% over 1?year, 2 years and 3 years, respectively. All studies included scored between 6 to 8 out of 9 on the NOS. The determinants of adherence and persistence to oral bisphosphonates included geographic residence, marital status, tobacco use, educational status, income, hospitalisation, medication type and dosing frequency.ConclusionsWhile a number of studies reported high levels of persistence and adherence, the findings of this review suggest that patient persistence and adherence with oral bisphosphonates medications was poor and reduced notably over time. Overall, adherence was suboptimal. To maximise adherence and persistence to oral bisphosphonates, it is important to consider possible determinants, including characteristics of the patients.
