Outcomes in GLP-1 RA-Experienced Patients Switching to Once-Weekly Semaglutide in a Real-World Setting: The Retrospective, Observational EXPERT Study.
Ontology highlight
ABSTRACT: Introduction
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are highly effective for glycaemic control and weight loss in patients with type 2 diabetes (T2D). In this retrospective, observational study, we analysed glycated haemoglobin (HbA1c) and weight following switching to semaglutide from any other GLP-1 RA, using US electronic health records and prescription data.Methods
Adults (≥ 18 years old) with T2D required at least one prescription for injectable semaglutide at index date (treatment switch), at least one prescription for any other GLP-1 RA in the previous 365 days, a baseline HbA1c and/or weight measurement in the 90 days pre-index and a follow-up measurement at 180 and 365 days post-index. HbA1c and weight cohorts were analysed separately using an ANCOVA model. Sensitivity analyses were conducted in patients with at least two prescriptions for pre-switch GLP-1 RA. A secondary analysis compared subgroups receiving different GLP-1 RAs pre-switch.Results
Patients with HbA1c (n = 710) and weight (n = 921) data had similar baseline characteristics. Significant reductions in HbA1c at 6 months (0.7%; 95% confidence interval [CI] - 0.8, - 0.6) were sustained at 12 months. Weight reductions were significant at 6 months (- 2.1 kg; 95% CI - 2.6, - 1.6) and greater at 12 months (- 2.8 kg; 95% CI - 3.9, - 1.8). These patterns were consistent with the two-prescription sensitivity analysis and independent of the pre-switch GLP-1 RA.Conclusion
Switching to injectable semaglutide from any other GLP-1 RA was associated with significant improvements in glycaemic control and weight. Our findings support decision-making in clinical practice in patients with an indication to switch between GLP-1 RAs.

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:BackgroundA once-weekly, 2.4-mg dose of subcutaneous semaglutide, a glucagon-like peptide-1 receptor agonist, is used to treat obesity in adults, but assessment of the drug in adolescents has been lacking.MethodsIn this double-blind, parallel-group, randomized, placebo-controlled trial, we enrolled adolescents (12 to <18 years of age) with obesity (a body-mass index [BMI] in the 95th percentile or higher) or with overweight (a BMI in the 85th percentile or higher) and at least one weight-related coexisting condition. Participants were randomly assigned in a 2:1 ratio to receive once-weekly subcutaneous semaglutide (at a dose of 2.4 mg) or placebo for 68 weeks, plus lifestyle intervention. The primary end point was the percentage change in BMI from baseline to week 68; the secondary confirmatory end point was weight loss of at least 5% at week 68.ResultsA total of 201 participants underwent randomization, and 180 (90%) completed treatment. All but one of the participants had obesity. The mean change in BMI from baseline to week 68 was -16.1% with semaglutide and 0.6% with placebo (estimated difference, -16.7 percentage points; 95% confidence interval [CI], -20.3 to -13.2; P<0.001). At week 68, a total of 95 of 131 participants (73%) in the semaglutide group had weight loss of 5% or more, as compared with 11 of 62 participants (18%) in the placebo group (estimated odds ratio, 14.0; 95% CI, 6.3 to 31.0; P<0.001). Reductions in body weight and improvement with respect to cardiometabolic risk factors (waist circumference and levels of glycated hemoglobin, lipids [except high-density lipoprotein cholesterol], and alanine aminotransferase) were greater with semaglutide than with placebo. The incidence of gastrointestinal adverse events was greater with semaglutide than with placebo (62% vs. 42%). Five participants (4%) in the semaglutide group and no participants in the placebo group had cholelithiasis. Serious adverse events were reported in 15 of 133 participants (11%) in the semaglutide group and in 6 of 67 participants (9%) in the placebo group.ConclusionsAmong adolescents with obesity, once-weekly treatment with a 2.4-mg dose of semaglutide plus lifestyle intervention resulted in a greater reduction in BMI than lifestyle intervention alone.

Project description:AimsThis study aims to evaluate the effectiveness and tolerability of once-weekly glucagon-like peptide receptor agonists (OW GLP-1RAs) and to assess the clinical benefits of switching from one GLP-1RA to another (switchers) in a routine clinical setting.Materials and methodsThis is a retrospective, real-world cohort study, based on electronic medical records utilized in one Italian diabetes clinic. Estimated mean changes in HbA1c and body weight after 6 and 12 months from the first prescription of a long-acting GLP1-RA were evaluated using longitudinal linear mixed models for repeated measures. The effectiveness of the three long-acting GLP1-RAs was compared separately in the GLP1-RA naive and switchers cohorts, after propensity score adjustment.ResultsInitiating a long-acting GLP1-RA was associated with statistically significant improvements in HbA1c (-1%) and body weight (-2.6 kg) after 6 months, and benefits were maintained after 12 months. In GLP1-RA naive cohort, semaglutide showed the largest effect on HbA1c (-1.55%; 95%CI, -1.77;-1.34) and body weight (-3.76 kg; 95%CI, -5.05;-2.47) at 6 months, maintained at 12 months (-1.55%; 95%CI, -1.82;-1.28 and -6.29 kg; 95%CI, -7.94;-4.63). In the switchers' cohort, statistically significant reductions at 6 months in HbA1c and body weight were documented with semaglutide and dulaglutide only, with semaglutide associated with the most marked reduction (-0.84%; 95%CI, -1.03;-0.65 and -3.43 kg; 95%, -4.67;-2.19). Dropout rates were 9.2%, 28.5%, and 41.7% in semaglutide, dulaglutide, and exenatide groups, respectively.ConclusionsThe effectiveness and tolerability of the OW GLP-1RAs in the real world were documented. Semaglutide was associated with the highest response without impact on safety. Clinical improvements were obtained even in switchers, especially in those switching to semaglutide.

Project description:Non-alcoholic fatty liver disease (NAFLD) is an important common comorbidity in individuals with type 2 diabetes (T2DM). Although some glucagon-like peptide-1 receptor agonists (GLP-1RAs) have beneficial effects on NAFLD, the efficacy of once-weekly semaglutide has not been established. This was a subanalysis of the SWITCH-SEMA 1 study, a multicenter, prospective, randomized, parallel-group trial comparing switching from liraglutide or dulaglutide to once-weekly semaglutide in subjects with T2DM (SWITCH) versus continuing current GLP-1RAs (Continue) for 24 weeks. This subanalysis consisted of participants who were suspected to have NAFLD [fatty liver index (FLI) ≥ 30]. In total, 58 participants met the criteria of this subanalysis. There were no statistical differences in baseline characteristics between the SWITCH (n = 31) and Continue groups (n = 27). FLI significantly improved during treatment in the SWITCH group (68.6 to 62.7) but not in the Continue group (71.1 to 72.3) (p < 0.01). The improvement of FLI in the SWITCH group was greater in switching from dulaglutide to semaglutide and significantly correlated with older age (p = 0.016) and lower baseline FLI (p < 0.01). The multiple linear regression analysis revealed that the switch from dulaglutide was associated with an improvement in FLI (p = 0.041). Switching from conventional GLP-1RAs to once-weekly semaglutide might be beneficial for individuals with NAFLD complicated with T2DM.

Project description:IntroductionSURE Netherlands (NCT03929679) evaluated the use of once-weekly (OW) semaglutide, a glucagon-like peptide 1 receptor agonist (GLP-1RA), in routine clinical care for individuals with type 2 diabetes (T2D).MethodsAdults (age ≥ 18 years) with T2D were enrolled into the single-arm study. The primary endpoint was change from baseline to end of study (EOS; approx. 30 weeks) in glycated haemoglobin (HbA1c). Secondary endpoints were change from baseline to EOS in body weight (BW) and waist circumference (WC). Proportions of participants achieving predefined HbA1c targets and weight-loss responses at EOS, safety, health-related quality of life (HRQoL) and treatment satisfaction were assessed.ResultsIn total, 211 participants (mean age 60.5 years; diabetes duration 13.3 years) initiated semaglutide; most were receiving metformin (82.9%) and/or basal insulin (59.2%) at baseline, and 6.2% switched from another GLP-1RA. Mean baseline HbA1c, BW and WC were 8.6%, 105.2 kg and 118.8 cm. In the 186 (88.2%) participants receiving semaglutide at EOS, mean reduction in HbA1c with semaglutide was - 1.2%-points (95% [confidence interval] CI - 1.3; - 1.0; p < 0.0001), with 124 (70.5%), 95 (54.0%) and 65 (36.9%) participants achieving HbA1c targets of < 8.0%, < 7.5% and < 7.0%, respectively. Mean reduction in BW was - 7.8 kg [95% CI - 8.7; - 6.8; p < 0.0001], corresponding to relative reduction of - 7.5% [95% CI - 8.4; - 6.6; p < 0.0001]. Improvements in WC (- 8.8 cm [95% CI - 10.4; - 7.2; p < 0.0001]), HRQoL and treatment satisfaction were observed, including across most Short-Form 36 Health Survey domains. One serious adverse drug reaction (cholecystitis) was reported. Eight participants (all receiving concomitant insulin) experienced severe or documented hypoglycaemia.ConclusionIndividuals with T2D treated with OW semaglutide experienced significant and clinically relevant improvements in glycaemic control and BW from baseline. These results from a diverse real-world population in the Netherlands support the use of OW semaglutide in treating adults with T2D in routine clinical practice.

Project description:The effect of semaglutide, a once-weekly human glucagon-like peptide-1 (GLP-1) analog in development for type 2 diabetes (T2D), on the bioavailability of a combined oral contraceptive was investigated. Postmenopausal women with T2D (n?=?43) on diet/exercise?±?metformin received ethinylestradiol (0.03?mg)/levonorgestrel (0.15?mg) once daily for 8 days before (semaglutide-free) and during (steady-state 1.0?mg) semaglutide treatment (subcutaneous once weekly; dose escalation: 0.25?mg 4 weeks; 0.5?mg 4 weeks; 1.0?mg 5 weeks). Bioequivalence of oral contraceptives was established if 90%CI for the ratio of pharmacokinetic parameters during semaglutide steady-state and semaglutide-free periods was within prespecified limits (0.80-1.25). The bioequivalence criterion was met for ethinylestradiol area under the curve (AUC0-24?h ) for semaglutide steady-state/semaglutide-free; 1.11 (1.06-1.15). AUC0-24?h was 20% higher for levonorgestrel at semaglutide steady-state vs. semaglutide-free (1.20 [1.15-1.26]). Cmax was within bioequivalence criterion for both contraceptives. Reductions (mean?±?SD) in HbA1c (-1.1?±?0.6%) and weight (-4.3?±?3.1?kg) were observed. Semaglutide pharmacokinetics were compatible with once-weekly dosing; the semaglutide dose and dose-escalation regimen were well tolerated. Adverse events, mainly gastrointestinal, were mild to moderate in severity. Asymptomatic increases in mean amylase and lipase were observed. Three subjects had elevated alanine aminotransferase levels ?3x the upper limit of normal during semaglutide/oral contraceptive coadministration, which were reported as adverse events, but resolved during follow-up. Semaglutide did not reduce the bioavailability of ethinylestradiol and levonorgestrel.

Project description:OBJECTIVE:The aim of this study was to assess the cost effectiveness of semaglutide versus dulaglutide, as an add-on to metformin monotherapy, for the treatment of type 2 diabetes (T2D), from a Canadian societal perspective. METHODS:The Swedish Institute for Health Economics Cohort Model of T2D was used to assess the cost effectiveness of once-weekly semaglutide (0.5 or 1.0 mg) versus once-weekly dulaglutide (0.75 or 1.5 mg) over a 40-year time horizon. Using data from the SUSTAIN 7 trial, which demonstrated comparatively greater reductions in glycated hemoglobin (HbA1c), body mass index and systolic blood pressure with semaglutide, compared with dulaglutide, a deterministic base-case and scenario simulation were conducted. The robustness of the results was evaluated with probabilistic sensitivity analyses and 15 deterministic sensitivity analyses. RESULTS:The base-case analysis indicated that semaglutide is a dominant treatment option, compared with dulaglutide. Semaglutide was associated with lower total costs (Canadian dollars [CAN$]) versus dulaglutide for both low-dose (CAN$113,287 vs. CAN$113,690; cost-saving: CAN$403) and high-dose (CAN$112,983 vs. CAN$113,695; cost-saving: CAN$711) comparisons. Semaglutide resulted in increased quality-adjusted life-years (QALYs) and QALY gains, compared with dulaglutide, for both low-dose (11.10 vs. 11.07 QALYs; +?0.04 QALYs) and high-dose (11.12 vs. 11.07 QALYs; +?0.05 QALYs) comparisons. The probabilistic sensitivity analysis showed that for 66-73% of iterations, semaglutide was either dominant or was considered cost effective at a willingness-to-pay threshold of CAN$50,000. CONCLUSIONS:From a Canadian societal perspective, semaglutide may be a cost-effective treatment option versus dulaglutide in patients with T2D who are inadequately controlled on metformin monotherapy.

Project description:IntroductionSemaglutide once-weekly (QW) is a novel glucagon-like peptide-1 (GLP-1) analogue administered at a 0.5 or 1.0 mg dose. In the absence of head-to-head trials between semaglutide QW and other GLP-1 receptor agonists (GLP-1 RAs) in a Japanese population, a network meta-analysis (NMA) was performed. The objective was to assess the relative efficacy and safety of semaglutide QW vs GLP-1 RAs in Japanese patients with type 2 diabetes (T2DM), with a specific focus on the comparison between semaglutide 0.5 mg QW and dulaglutide 0.75 mg QW.MethodsA systematic review (SR) and supplementary Japanese searches were conducted to identify trials of GLP-1 RAs in Japanese patients on diet and exercise, who have previously received 0-1 oral antidiabetic drugs (OADs). Data at 52-56 weeks were extracted for the following outcomes (feasible for analysis in an NMA): glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), weight, systolic blood pressure (SBP), and overall hypoglycemia. The data were synthesized using an NMA and a Bayesian framework.ResultsFour trials, identified from the SR and Japanese-specific searches, were relevant for inclusion in the NMA. When compared to dulaglutide 0.75 mg QW, semaglutide 0.5 mg QW was shown to provide significant reductions in HbA1c [- 0.61% (12.3 mmol/mol)], weight (- 1.45 kg), SBP (- 5.03 mmHg), and FPG (- 1.26 mmol/L). No significant differences in the proportion of patients achieving a HbA1c level < 7% (53 mmol/mol) or the risk of overall hypoglycemia were observed between semaglutide 0.5 mg QW and dulaglutide 0.75 mg QW.ConclusionOverall, semaglutide 0.5 mg QW was associated with significant reductions from baseline in HbA1c, weight, SBP, and FPG compared with dulaglutide 0.75 mg QW in Japanese patients with T2DM. These data may provide valuable evidence for clinical decision-making, cost-effectiveness analyses, and health technology appraisal (HTA) requirements.FundingNovo Nordisk Pharma Ltd.

Project description:INTRODUCTION:Semaglutide, a new treatment option approved for the treatment of patients with type 2 diabetes mellitus, is a glucagon-like peptide-1 receptor agonist to be injected subcutaneously once weekly. This analysis used a population pharmacokinetic model of semaglutide to identify clinically relevant covariates for exposure. METHODS:A total of 1612 patients with up to seven pharmacokinetic observations each were included in the analysis. All subjects had type 2 diabetes mellitus and were enrolled in one of five trials in the phase III development program for subcutaneous semaglutide once weekly (the SUSTAIN program). The treatment duration of the trials varied from 30 to 104 weeks. RESULTS:No clinically relevant effects on the exposure were seen for sex, age, race, ethnicity, renal function, or injection site used, and semaglutide exposure was stable over time. Of the covariates chosen, only body weight had a relevant effect on the exposure of semaglutide. Few subjects developed semaglutide antibodies, and the antibodies had no effect on exposure. Dose proportionality was shown for the 0.5 mg and 1.0 mg maintenance doses of semaglutide. CONCLUSION:The population pharmacokinetic study showed that semaglutide exposure is not affected by covariates other than body weight at either a maintenance dose of 0.5 or 1.0 mg semaglutide. Therefore, we conclude that no semaglutide dose adjustments are needed in different populations. This finding is to be further explored in an exposure-response analysis. TRIAL REGISTRATION:The trials were registered at ClinicalTrials.gov (identifiers: NCT02054897, NCT01930188, NCT01885208, NCT01720446 and NCT02207374). FUNDING:Novo Nordisk A/S, Bagsværd, Denmark.

Project description:IntroductionOnce-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.MethodsIn 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.ResultThe 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.ConclusionPatients 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.Trial registrationClinicalTrials.gov Identifier NCT03876015.
