Patient-reported outcomes among patients using exenatide twice daily or insulin in clinical practice in six European countries: the CHOICE prospective observational study

The Antidepressant Effects of GLP-1 Receptor Agonists: A Systematic Review and Meta-Analysis

AIM/HYPOTHESIS

Emerging evidence suggests that glucagon-like peptide-1 receptor agonists (GLP-1RAs) may exert positive effects in patients with depression. Our aim was to conduct a systematic review and meta-analysis to examine the antidepressant effects of GLP-1RAs.

METHODS

Randomized controlled trials and prospective cohort studies investigating the effects of GLP-1RAs versus placebo or other antidiabetic therapies on depressive symptoms were searched for using multiple electronic sources (CENTRAL, PubMed, EMBASE, PsycINFO, World Health Organization International Clinical Trials Registry Platform, ClinicalTrials.gov, China Network Knowledge Infrastructure, China Biomedical Database, Wan Fang data, and Chinese Scientific Journals Database) from inception to February 16, 2023. We utilized a random effects model to analyze standardized mean differences for the change in depression rating scales comparing GLP-1RA treated groups with control treated groups.

RESULTS

The meta-analysis comprising 2,071 participants included 5 randomized controlled trials and 1 prospective cohort study. The meta-analysis indicated that the change from baseline in depression rating scale scores decreased significantly when patients received treatment with GLP-1RAs compared to control treatments (SMD = -0.12, 95% CI [-0.21, -0.03], pSMD <0.01, I2 = 0%, pQ = 0.52). The subgroup analysis showed that the effects of GLP-1RAs on depressive symptoms were consistent in patients with Type 2 diabetes mellitus (SMD = -0.12, 95% CI [-0.21, -0.03], pSMD <0.01, I2 = 2%, pQ = 0.40).

CONCLUSIONS

Adults treated with GLP-1RAs showed significant reductions in the depression rating scale scores compared to those treated with control substances. Our findings suggest that GLP-1RAs may be a potential treatment for alleviating depressive symptoms in humans.

The Real-World Observational Prospective Study of Health Outcomes with Dulaglutide and Liraglutide in Type 2 Diabetes Patients (TROPHIES): Final patient-reported outcomes at 24 months

AIM

To report health-related patient-reported outcomes (PROs) in people with type 2 diabetes (T2D) initiating their first injectable glucose-lowering medication (GLM) with two commonly prescribed glucagon-like peptide-1 receptor agonists (GLP-1RAs) from the prospective, observational TROPHIES study (The Real-World Observational Prospective Study of Health Outcomes with Dulaglutide and Liraglutide in Type 2 Diabetes Patients).

MATERIALS AND METHODS

TROPHIES was a two-cohort, 24-month study conducted in France, Germany and Italy. Adults with a T2D diagnosis, naïve to injectable treatment for T2D and prescribed dulaglutide or liraglutide as their first injectable GLM, were eligible for inclusion. Study objectives included describing the following PROs associated with the treatment of T2D with GLP-1RAs: health-related quality of life; impact of weight on self-perception; life and work productivity; and patient satisfaction with treatment and injection device. Additional analyses formally compared PRO measures between the treatment cohorts.

RESULTS

Overall, improvements from baseline in PRO scores were observed among people who started dulaglutide or liraglutide. A more pronounced trend of improvement was observed in the dulaglutide cohort for changes from baseline in treatment satisfaction and impact of weight on self-perception, supported by statistically significant differences between treatment cohorts in additional comparative analyses at 12, 18 and 24 months. More positive patient perceptions of the injection device were observed with dulaglutide than with liraglutide.

CONCLUSIONS

Improvements in PROs observed in TROPHIES, which were more evident with dulaglutide than liraglutide, reflect a relevant clinical benefit. From the patients' perspective, satisfaction, and confidence in continuing treatment with GLP-1RAs is likely to contribute to long-term treatment persistence.

Health State Utility Values of Type 2 Diabetes Mellitus and Related Complications: A Systematic Review and Meta-Analysis

OBJECTIVES

This study aims to synthesize health state utility values (HSUVs) of type 2 diabetes mellitus (T2DM) and its related complications published in the literature, conducting a meta-analysis of the data when possible.

METHODS

We conducted a systematic search in MEDLINE and School of Health and Related Research Health Utilities Database repository. Studies focused on T2DM and its complications reporting utility values elicited using direct and indirect methods were selected. We categorized the results according to the instrument to describe health and meta-analyzed them accordingly. Data included in the analysis were pooled in a fixed-effect model by the inverse of variance mean and random-effects DerSimonian-Laird method. Two approaches on sensitivity analysis were performed: leave-one-out method and including data of HSUVs obtained by foreign population value sets.

RESULTS

We identified 70 studies for the meta-analysis from a total of 467 studies. Sufficient data to pool T2DM HSUVs from EQ-5D instrument, hypoglycemia, and stroke were obtained. HSUVs varied from 0.7 to 0.92 in direct valuations, and the pooled mean of 3-level version of EQ-5D studies was 0.772 (95% confidence interval 0.763-0.78) and of 5-level version of EQ-5D 0.815 (95% confidence interval 0.808-0.823). HSUVs of complications varied from 0.739 to 0.843, or reductions of HSUVs between -0.014 and -0.094. In general, HSUVs obtained from 3-level version of EQ-5D and Health Utility Index 3 instruments were lower than those directly elicited. A considerable amount of heterogeneity was observed. Some complications remained unable to be pooled due to scarce of original articles.

CONCLUSIONS

T2DM and its complications have a considerable impact on health-related quality of life. 5-level version of EQ-5D estimates seems comparable with direct elicited HSUVs.

The therapeutic potential of GLP-1 analogues for stress-related eating and role of GLP-1 in stress, emotion and mood: a review

Stress and low mood are powerful triggers for compulsive overeating, a maladaptive form of eating leading to negative physical and mental health consequences. Stress-vulnerable individuals, such as people with obesity, are particularly prone to overconsumption of high energy foods and may use it as a coping mechanism for general life stressors. Recent advances in the treatment of obesity and related co-morbidities have focused on the therapeutic potential of anorexigenic gut hormones, such as glucagon-like peptide 1 (GLP-1), which acts both peripherally and centrally to reduce energy intake. Besides its appetite suppressing effect, GLP-1 acts on areas of the brain involved in stress response and emotion regulation. However, the role of GLP-1 in emotion and stress regulation, and whether it is a viable treatment for stress-induced compulsive overeating, has yet to be established. A thorough review of the pre-clinical literature measuring markers of stress, anxiety and mood after GLP-1 exposure points to potential divergent effects based on temporality. Specifically, acute GLP-1 injection consistently stimulates the physiological stress response in rodents whereas long-term exposure indicates anxiolytic and anti-depressive benefits. However, the limited clinical evidence is not as clear cut. While prolonged GLP-1 analogue treatment in people with type 2 diabetes improved measures of mood and general psychological wellbeing, the mechanisms underlying this may be confounded by associated weight loss and improved blood glucose control. There is a paucity of longitudinal clinical literature on mechanistic pathways by which stress influences eating behavior and how centrally-acting gut hormones such as GLP-1, can modify these.

The Real-World Observational Prospective Study of Health Outcomes with Dulaglutide and Liraglutide in Type 2 Diabetes Patients (TROPHIES): Baseline Patient-Reported Outcomes

INTRODUCTION

Although patient-reported outcome (PRO) measures provide important information beyond clinical data, studies that assess the PROs of type 2 diabetes mellitus (T2DM) patients initiating injectable glucose-lowering medications in routine clinical practice are limited. We describe the perspectives of patients based on a diversified panel of generic and disease-specific PRO measures at the time of enrollment (baseline) in the TROPHIES study.

METHODS

TROPHIES is a 24-month prospective observational study performed in France, Germany, and Italy in patients with T2DM who initiated their first injectable glucose-lowering medication with once-weekly dulaglutide or once-daily liraglutide. To better understand the perspectives of these patients regarding their overall health, treatment satisfaction, and quality of life and work, the patients' responses to the following questionnaires were collected at baseline before they initiated treatment with dulaglutide or liraglutide: EQ-5D-5L (scale: 0-1), EQ-VAS (visual analog scale: 0-100), Impact of Weight on Self-Perceptions Questionnaire (IW-SP; scale: 0-100), Diabetes Treatment Satisfaction Questionnaire Status (DTSQs; scale: 0-36), and Diabetes Productivity Measure (DPM; scale: 0-100). Analyses were descriptive in nature, with higher scores reflecting better outcomes.

RESULTS

Data from patients at the time of enrollment were analyzed. At baseline, patients initiating dulaglutide (N = 1130) or liraglutide (N = 1051) rated their quality of life in terms of mean EQ-5D-5L index as 0.84 and 0.83, and in terms of mean EQ-VAS as 67.5 and 67.5, respectively. The mean baseline scores in patients initiating dulaglutide or liraglutide were 59.8 and 61.3 for IW-SP, 24.6 and 25.8 for DTSQs, 78.6 and 79.5 for DPM Life Productivity, and 87.5 and 86.8 for DPM Work Productivity, respectively.

CONCLUSION

The information from this varied panel of PRO instruments collected at baseline complements clinical outcomes data.

Semaglutide improves health-related quality of life versus placebo when added to standard of care in patients with type 2 diabetes at high cardiovascular risk (SUSTAIN 6)

AIM

To assess what drives change in health-related quality of life (HRQoL) in type 2 diabetes in the SUSTAIN 6 trial and identify potential mediators of the treatment effect of semaglutide on HRQoL scores.

MATERIALS AND METHODS

The Short Form (SF)-36v2® questionnaire [comprising physical component summary (PCS) and mental component summary (MCS)] was used to assess changes in HRQoL from baseline to week 104, by treatment, in a prespecified analysis. This post-hoc analysis assessed change in PCS and MCS using the following factors as parameter/covariate, using descriptive statistics and linear regressions: major adverse cardiac events, hypoglycaemia, gastrointestinal adverse events, at least one episode of nausea, vomiting or diarrhoea, and change in glycated haemoglobin (HbA1c), body weight, blood pressure, heart rate and estimated glomerular filtration rate.

RESULTS

Mean change in overall PCS score was +1.0 with semaglutide versus +0.4 with placebo, and +0.5 versus -0.2 for MCS. The treatment effect of semaglutide versus placebo (unadjusted estimate) was 0.7 [(95% confidence interval 0.1, 1.2); P = 0.018] on PCS and this was reduced when adjusted for change in HbA1c [0.4 (-0.2, 1.0), P = .167] and body weight [0.3 (-0.3, 0.9), P = .314]. The unadjusted treatment effect on MCS [0.7 (-0.0, 1.5), P = .054] was only reduced when adjusted for change in HbA1c [0.3 (-0.4, 1.1), P = .397]. When adjusting for all other parameters separately, the estimated effect of semaglutide on PCS and MCS qualitatively did not change.

CONCLUSIONS

Semaglutide improved HRQoL versus placebo; greater improvements with semaglutide versus placebo were possibly mediated, in part, by change in HbA1c and body weight. Clinicaltrials.gov: NCT01720446 (SUSTAIN 6).

Assessment of the benefit of achieving complete versus almost complete skin clearance in psoriasis: a patient's perspective

Background: Psoriasis is characterized by thick and scaly plaques. The Dermatology Life Quality Index (DLQI) and Physician Global Assessment (PGA) can be used to define its severity.Objective: To assess the impact of complete clearance of skin versus almost clear skin across various disease measures.Methods: Data were collected in a survey of US dermatologists and patients with psoriasis from November 2016-January 2017. Dermatologists completed a 6-point PGA (0 = clear skin, 1 = almost clear skin). Patients completed the DLQI and Work Productivity and Activity Impairment questionnaire (WPAI). Patients with clear and almost clear skin were compared using analysis of covariance for continuous variables, and multivariate logistic regression analysis for categorical variables.Results: Data for 99 and 160 patients with clear and almost clear skin, respectively, were included in the analyses. Patients with clear skin reported less frequent and lower intensity itching, lower total DLQI score (indicating better health-related quality of life), and less impairment of overall work productivity than patients with almost clear skin (all: p < 0.05).Limitations: Limitations relating to general survey methodology.Conclusion: Patients perceived a meaningful difference between clear and almost clear skin. Clear skin is now a realistic treatment target with newer biologics approved in psoriasis.

Health-related quality of life in adults with type 2 diabetes mellitus starting with new glucose lowering drugs: An inception cohort study

AIMS

To assess baseline and change after 26-weeks in health-related quality of life (HRQoL) among adults with type 2 diabetes mellitus (T2DM) initiating one of the new glucose lowering drugs (GLD) in daily practice.

METHODS

Inception cohort of patients who initiated one of dipeptidyl peptidase 4 inhibitors (DPP-4), glucagon-like peptide-1 analogues (GLP-1) or sodium-glucose cotransporter inhibitors (SGLT2) drugs. A baseline questionnaire collected socio-demographic and self-reported clinical data. HRQoL was assessed by the Euroqol-5D. Participants were divided into: (1) incident new users (INU) (who used for the first time one of the monitored GLD and had no current or prior experience with DPP-4/GLP-1/SGLT2) and (2) prevalent new users (PNU) (who had previously used at least one GLD of the monitored drug classes, but not the inception drug). Multivariate regression explored factors associated with a meaningful change in HRQoL.

RESULTS

1303 patients. Over 26weeks, a mean positive change in the EQ-5D scores, were observed. No differences between INU and PNU were found. Participants with worse health conditions (e.g. presence and number of chronic diseases, obese) at baseline were more likely to experience larger improvements in HRQoL.

CONCLUSIONS

Over 26-weeks, T2DM patients starting with, or switching to new GLD maintained or modestly increased their HRQoL.

Patient preferences for treatment in type 2 diabetes: the Italian discrete-choice experiment analysis

AIMS

Several drug classes are now available to achieve a satisfactory metabolic control in patients with type 2 diabetes (T2DM), but patients' preferences may differ.

METHODS

In a discrete-choice experiment, we tested T2DM patients' preferences for recent antidiabetic drugs, in the event that their treatment might require intensification. The following attributes were considered: (a) route of administration; (b) type of delivery; (c) timing; (d) risk of adverse events; (e) effects on body weight. Twenty-two possible scenarios were built, transferred into 192 paired choices and proposed to 491 cases naïve to injectable treatments and 171 treated by GLP-1 receptor agonists (GLP-1RAs). Analyses were performed by descriptive statistics and random effects logit regression model.

RESULTS

Preferences according to dosing frequency, risk of nausea and urinary tract infections (UTls) were similar across groups, age, sex and BMI. Administration route and delivery type accounted for 1/3 of relative importance; the risk of UTIs, nausea and dosing frequency for ≈ 20% each, and weight loss for only 6%. Two significant interactions emerged (p < 0.01): type of delivery × group, and weight change × BMI class. Irrespective of previous treatment, the three preferred choices were injectable, coupled with weekly dosing and a ready-to-use device (first two choices). In a regression model, being naïve or non-naïve changed the ranking of preferences (p < 0.001), and the order was systematically shifted towards injectable medications in non-naïve subjects.

CONCLUSION

Easy-to-deliver, injectable treatment is preferred in T2DM, independently of treatment history, and previous experience with GLP-1RAs strengthens patients' willingness to accept injectable drugs.

Health-Related Quality of Life Assessments with Once-Weekly Glucagon-Like Peptide-1 Receptor Agonists in Type 2 Diabetes Mellitus

Type 2 diabetes (T2DM) is associated with significant impairment in health-related quality of life (HRQoL). A patient-centered collaborative approach is recommended to optimize clinical outcomes, including HRQoL, in this patient population. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) provide effective glycemic control and have demonstrated beneficial effects on HRQoL and treatment satisfaction. Available once-weekly GLP-1 RAs may offer enhanced convenience compared with daily GLP-1 RAs and include exenatide extended-release (ER), dulaglutide, and semaglutide. This article reviews the impact of once-weekly GLP-1 RAs on HRQoL and treatment satisfaction in patients with T2DM. Compared with oral antihyperglycemic drugs, insulin, and daily GLP-1 RAs, once-weekly GLP-1 RAs offer benefits with regard to HRQoL and treatment satisfaction. These benefits appear to be largely mediated by relative drug effects on glycemic control, weight, and hypoglycemia. While there was not an overall class benefit of once-weekly GLP-1 RAs compared with daily GLP-1 RAs on HRQoL and treatment satisfaction, results suggested that once-weekly GLP-1 RAs may enhance certain elements of treatment satisfaction and increase willingness to continue treatment. In 2 studies comparing once-weekly GLP-1 RAs with each other, semaglutide produced significantly greater improvement in overall treatment satisfaction compared with exenatide ER but not dulaglutide. Once-weekly GLP-1 RAs represent an effective and convenient treatment option that may potentially increase treatment satisfaction and enhance adherence, contributing to improved health outcomes.

Treatment Strategy for Type 2 Diabetes with Obesity: Focus on Glucagon-like Peptide-1 Receptor Agonists

PURPOSE

The progressive nature of type 2 diabetes mellitus (T2DM) calls for step-wise intensification of therapy for maintaining normal glycemic levels and lowering cardiovascular (CV) risk. Because obesity is a prominent risk factor and comorbidity of T2DM, it further elevates the CV risk in T2DM. Therefore, it is vital to manage weight, obesity, and glycemic parameters for effective T2DM management. Few oral antidiabetic drugs (sulfonylureas and thiazolidinediones) and insulin are not suitable for obese patients with T2DM because these drugs cause weight gain. The present review discusses the place of glucagon-like peptide-1 receptor agonists (GLP-1RAs) in the treatment of obese patients with T2DM and the significance of these drugs in the prevention of future CV risk in patients with T2DM.

METHODS

A literature search of PubMed and EMBASE was conducted by using the search terms T2DM, GLP-1RAs, obesity, and cardiovascular complication. Randomized controlled trials measuring the effect of GLP-1RAs versus that of placebo on CV outcomes were included in the review.

FINDINGS

GLP-1RAs have emerged as a therapeutic alternative; these drugs exert their actions by providing glycemic control, improving insulin resistance and ö̇-cell function, and reducing weight. The risk of hypoglycemia with GLP-1RAs is minimal; however, GLP-1RAs are associated with gastrointestinal adverse events and raise concerns regarding pancreatitis. Combining GLP-1RAs with insulin analogues results in higher efficacy, a lowered insulin dose, and reduced insulin-related hypoglycemia and weight gain. Longer acting GLP-1RAs are also associated with improvement in medication adherence. Improvement in CV risk factors such as blood pressure and lipid profile further increases their usability for improving CV outcomes.

IMPLICATIONS

Overall, the properties of GLP-1RAs make them suitable for combination with oral antidiabetic drugs in the early stages of T2DM and with insulins in the later stages for optimizing comprehensive management of the disease.

Patient Reported Outcomes (PROs) used in recent Phase 3 trials for Type 2 Diabetes: A review of concepts assessed by these PROs and factors to consider when choosing a PRO for future trials

AIMS

Many treatment options are available for people with Type 2 Diabetes (T2D). While the goal of treatment is to reach target HbA1c levels, the psychological experience may be more tangible and meaningful for the patient. Together with biomarkers, Patient-Reported Outcome (PRO) data provide a holistic understanding of the clinical and psychosocial impact of T2D and its treatment.

METHODS

A literature review was conducted in multiple databases to identify PRO endpoints used in Phase 3 trials of newer classes of drugs for the treatment of T2D.

RESULTS

This review identified five PRO concepts which were evaluated as endpoints in Phase 3 trials of GLP-1 receptor agonists, novel insulins, SGLT-2 inhibitors, and DPP-4 inhibitors; symptoms, health-related quality of life, psychological well-being, satisfaction with treatment/health and impact of weight. Twenty PRO questionnaires were used to measure these concepts/endpoints directly from patients. The relevance of, and scientific basis for, these concepts as endpoints are discussed, the similarities and differences between questionnaires targeting the same concepts/endpoints are explored, and the sensitivity of the questionnaires to the experimental intervention is summarized. In addition, factors that should be considered when choosing PROs for future T2D trials are discussed.

CONCLUSIONS

The information gained from PROs in clinical trial research is important in defining treatment benefit within the context of the trial, and the potential benefit (i.e. better adherence) in clinical practice. However, variable results have been observed in recent trials and careful and systematic consideration should be given to PRO selection for future studies of T2D.

A qualitative examination of the content validity of the EQ-5D-5L in patients with type 2 diabetes

Background

The EQ-5D is frequently used to derive utilities for patients with type 2 diabetes (T2D). Despite widely available quantitative psychometric data on the EQ-5D, little is known about content validity in this population. Thus, the purpose of this qualitative study was to examine content validity of the EQ-5D in patients with T2D.

Methods

Patients with T2D in the UK completed concept elicitation interviews, followed by administration of the EQ-5D-5L and cognitive interviewing focused on the instrument’s relevance, clarity, and comprehensiveness.

Results

A total of 25 participants completed interviews (52.0 % male; mean age = 53.5 years). Approximately half (52 %) reported that the EQ-5D-5L was relevant to their experience with T2D. When asked if each individual item was relevant to their experience with T2D, responses varied widely (24.0 % said the self-care item was relevant; 68.0 % said the anxiety/depression item was relevant). Participants frequently said items were not relevant to themselves, but could be relevant to patients with more severe diabetes. Most participants (92.0 %) reported that T2D and/or its treatment/monitoring requirements had an impact on their quality of life that was not captured by the EQ-5D-5L. Common missing concepts included food awareness/restriction (n = 13, 52.0 %); activities (n = 11, 44.0 %); emotional functioning other than depression/anxiety (n = 8, 32.0 %); and social/relationship functioning (n = 8, 32.0 %).

Conclusions

The results highlight strengths and potential limitations of the EQ-5D-5L, including missing content that could be important for some patients with T2D. Suggestions for addressing limitations are provided.

Five-year efficacy and safety data of exenatide once weekly: long-term results from the DURATION-1 randomized clinical trial

OBJECTIVE

To evaluate the 5-year efficacy and safety of once weekly exenatide.

PATIENTS AND METHODS

The Diabetes Therapy Utilization: Researching Changes in A1C, Weight and Other Factors Through Intervention with Exenatide Once Weekly (DURATION-1) randomized clinical trial consisted of a 30-week controlled phase (2 mg of exenatide once weekly vs 10 μg of exenatide twice daily) with an open-ended uncontrolled extension (once weekly exenatide only) in patients with type 2 diabetes mellitus on background glucose-lowering therapies (April 15, 2006, through February 21, 2012). At week 30, patients initially receiving 10 μg of exenatide twice daily switched to 2 mg of exenatide once weekly. Study end points included changes from baseline in hemoglobin A1c, fasting plasma glucose, weight, lipids, and blood pressure. Long-term safety data included adverse events, liver and renal function, and heart rate.

RESULTS

Of 258 extension-phase patients, 153 (59.3%) completed 5 years of treatment. Hemoglobin A1c levels were significantly and durably reduced from baseline (least-squares mean, -1.6%; 95% CI, -1.8% to -1.4%; vs -1.9% for exenatide once weekly at week 30), and 65 (43.9%) of 148 patients achieved hemoglobin A1c levels of less than 7.0%. Significant improvements in fasting plasma glucose level (-28.8 mg/dL; 95% CI, -36.2 to -21.5 mg/dL), weight (-3.0 kg; 95% CI, -4.6 to -1.3 kg), lipids, and diastolic blood pressure were observed, with minimal heart rate increase. Frequencies of nausea and injection-site reactions or nodules were decreased vs the initial 30-week controlled phase. Minor hypoglycemia occurred predominantly with sulfonylurea use, and no major hypoglycemia or new safety signals were observed.

CONCLUSION

Long-term once weekly exenatide treatment was generally well tolerated with sustained glycemic improvement, weight reduction, and improved markers of cardiovascular risk in patients with type 2 diabetes.
