Physician perceptions of GLP-1 receptor agonists in the UK

Physician Perceptions of Dose Escalation for Type 2 Diabetes Medications in the United States

INTRODUCTION

Medications used to treat type 2 diabetes (T2D) often require dose escalation to optimize effectiveness. Physician and patient perceptions of treatment characteristics of T2D medications have previously been examined, but little is known about perceptions of escalation to the optimal dose for each patient. This study examined physicians' perceptions of dose escalation for medications used to treat T2D.

METHODS

Data on dose escalation and other factors influencing decision-making for treatment of T2D were collected via an online survey of endocrinologists and primary care physicians in the USA.

RESULTS

The sample included 501 physicians (348 primary care physicians and 153 endocrinologists). Dose escalation was not frequently considered by physicians as a primary factor keeping patients' from reaching treatment goals (mentioned as a factor by only 7.6% of the sample) or a barrier to prescribing T2D medication (16.2%). Factors more likely to keep patients from reaching treatment goals included an unhealthy diet (86.6%) and medication adherence (77.4%). The most common reasons that physicians reported for escalating dose levels were the need for better glycemic control (reported by 89.8% of the sample), ability to decrease the total number of medications by increasing the dose of one medication (39.9%), and the need for the patient to lose weight (39.3%). Data reported by primary care physicians and endocrinologists followed similar patterns.

CONCLUSIONS

Although common with T2D treatments, escalating the dose of T2D medication was not perceived by physicians to be a significant barrier to attaining treatment goals or prescribing medication. Multiple factors contribute to the decision to escalate the dose of T2D medication.

Trends in Prescribing Preferences for Antidiabetic Medications Among Patients With Type 2 Diabetes in the U.K. With and Without Chronic Kidney Disease, 2006-2020

OBJECTIVE

To evaluate trends in antidiabetic medication initiation patterns among patients with type 2 diabetes mellitus (T2DM) with and without chronic kidney disease (CKD).

RESEARCH DESIGN AND METHODS

A retrospective cohort study using the UK Clinical Practice Research Datalink (2006-2020) was conducted to evaluate the overall, first-, and second line (after metformin) medication initiation patterns among patients with CKD (n = 38,622) and those without CKD (n = 230,963) who had T2DM.

RESULTS

Relative to other glucose-lowering therapies, metformin initiations declined overall but remained the first-line treatment of choice for both patients with and those without CKD. Sodium-glucose cotransporter-2 (SGLT2i) use increased modestly among patients with CKD, but this increase was more pronounced among patients without CKD; by 2020, patients without CKD, compared with patients with CKD, were three (28.5% vs. 9.4%) and six (46.3% vs. 7.9%) times more likely to initiate SGLT2i overall and as second-line therapy, respectively. Glucagon-like peptide 1 receptor agonist (GLP-1RA) use was minimal regardless of CKD status (<5%), whereas both dipeptidyl peptidase-4 inhibitor (DPP4i) and sulfonylurea use remained high among patients with CKD. For instance, by 2020, and among patients with CKD, DPP4i and sulfonylureas constituted 28.3% and 20.6% of all initiations, and 57.4% and 30.3% of second-line initiations, respectively.

CONCLUSIONS

SGLT2i use increased among patients with T2DM, but this increase was largely driven by patients without CKD. Work is needed to identify barriers associated with the uptake of therapies with proven cardiorenal benefits (e.g., SGLT2i, GLP-1RA) among patients with CKD.

Efficacy and safety of oral semaglutide in patients with non‐alcoholic fatty liver disease complicated by type 2 diabetes mellitus: A pilot study

Background and Aim

This study aimed to clarify the efficacy and safety of oral semaglutide treatment in patients with non‐alcoholic fatty liver disease (NAFLD) complicated by type 2 diabetes mellitus (T2DM).

Methods

This was a single‐arm, open‐label pilot study. Sixteen patients with NAFLD who received oral semaglutide for T2DM were included in the analysis. Oral semaglutide was initiated at a dose of 3 mg once daily, and the dose was sequentially increased to 7 mg at 4 weeks and 14 mg at 8 weeks (maintenance dose) until the end of the 24‐week trial.

Results

Body weight and levels of liver‐related biochemistry, plasma glucose, and hemoglobin A1c decreased significantly from baseline to 12 weeks. These significant decreases were maintained until the end of the trial. Additionally, levels of the homeostasis model assessment‐insulin resistance and triglyceride significantly decreased at 24 weeks. Controlled attenuation parameter (CAP) values significantly decreased from baseline to 24 weeks. Changes in body weight were correlated with those in levels of alanine aminotransferase (r = 0.52) and CAP (r = 0.72). As for liver fibrosis markers, significant decreases from baseline to 24 weeks in levels of the fibrosis‐4 index, ferritin, and type IV collagen 7 s were found; however, the liver stiffness measurement did not significantly decrease. Most adverse events were grade 1–2 transient gastrointestinal disorders.

Conclusions

Oral semaglutide treatment in patients with NAFLD complicated by T2DM improved impaired liver function, hypertriglyceridemia, insulin resistance, and hepatic steatosis, as well as improving diabetic status and reducing body weight.

Oral Semaglutide: Dosage in Special Situations

Glucagon-like peptide 1 receptor agonists (GLP1RAs) have recently gained momentum after the introduction of semaglutide, the first oral molecule in their class. In a recent article in this journal by Evans et al., a succinct overview of the utility of semaglutide is highlighted in the context of virtual diabetes care. To take this discussion further, this commentary describes the value and positioning of oral semaglutide in common clinical situations. Its insights assist in pragmatic placement of this drug in clinical practice. Special emphasis is laid on the use of oral semaglutide in persons already on injectable GLP-1RA formulations, those experiencing sudden changes in life style pattern due to religious, social, or professional commitments, individuals seeking help for urgent glycemic control, and those who face sudden change in their concomitant medications or comorbidities.

A survey of physician experience and treatment satisfaction prescribing once-weekly semaglutide injections for patients with type 2 diabetes in Canada

We assessed physicians' experiences of prescribing once-weekly (OW) semaglutide to patients with type 2 diabetes (T2D) in Canada. Physicians who had prescribed OW semaglutide to ≥2 patients with T2D in the past 12 months and had been doing so for ≥3 months were surveyed during 1-17 October 2018. Prescribing reasons, treatment satisfaction and reasons for discontinuation were assessed. Of the 50 participants, 72% and 54% were prescribed OW semaglutide due to its superior glycemic control and effect on weight, respectively. Most physicians were more satisfied with injection frequency (62%), effect on weight (60%), achieving HbA1c target (54%) and therapy simplicity (50%) with OW semaglutide versus other glucagon-like peptide-1 receptor agonists. Treatment discontinuations in 13% of OW semaglutide-treated patients were reported by physicians, primarily due to gastrointestinal symptoms (70%). The survey suggests that physicians are satisfied with the OW semaglutide clinical effects. Video Abstract: http://links.lww.com/CAEN/A34.

Meeting the Challenge of Virtual Diabetes Care: A Consensus Viewpoint on the Positioning and Value of Oral Semaglutide in Routine Clinical Practice

While glucagon-like peptide-1 receptor agonists (GLP-1 RAs), such as semaglutide, are among the most effective drugs for treating people with type 2 diabetes (T2D), they are clinically under-utilised. Until recently, the only route for semaglutide administration was via subcutaneous injection. However, an oral formulation of semaglutide was recently licensed, with the potential to address therapy inertia and increase patient adherence to treatment, which is essential in controlling blood glucose and reducing complications. The availability of oral semaglutide provides a new option for both clinicians and patients who are reluctant to use an injectable agent. This has been of particular importance in addressing the challenge of virtual diabetes care during the COVID-19 pandemic, circumventing the logistical problems that are often associated with subcutaneous medication administration. However, there remains limited awareness of the clinical and economic value of oral semaglutide in routine clinical practice. In this article, we present our consensus opinion on the role of oral semaglutide in routine clinical practice and discuss its value in reducing the burden of delivering diabetes care in the post-COVID-19 pandemic period of chronic disease management.

'For me, it didn't seem as drastic a step as being controlled by insulin': A qualitative investigation of expectations and experiences of non-insulin injectable therapy among adults with type 2 diabetes

AIMS

This qualitative study aims to explore beliefs, attitudes and experiences of injectable glucagon-like-peptide-1 receptor agonists (GLP-1RAs) use and discontinuation, as well as attitudes to further injectable treatment intensification, among adults with type 2 diabetes (T2D).

METHODS

Nineteen in-depth semi-structured interviews lasting (mean ± standard deviation) 45 ± 18 min were conducted, face-to-face (n = 14) or via telephone (n = 5). Transcripts were analysed using inductive template analyses. Eligible participants were English-speaking adults with T2D who had recently initiated (≤3 years) GLP-1RA treatment.

RESULTS

Participants were aged 28-72 years, who predominantly lived in metropolitan areas (n = 15), and had an experience of daily (n = 11) and/or once-weekly (n = 13) GLP-1RA formulations. Six participants had discontinued treatment and seven had trialled two or more formulations. Expectations and experiences of GLP-1RA were related to the perceived: (1) symbolism and stigma of injectable diabetes treatment; (2) ease of injectable administration and device preferences; (3) treatment convenience and social impact; (4) treatment efficacy and benefits, and; (5) negative treatment side effects. Some participants reported increased receptiveness to insulin therapy following their GLP-1RA experience, others emphasised unique concerns about insulin beyond injectable administration.

CONCLUSIONS

This study provides a novel understanding of expectations and experience of non-insulin injectables among Australian adults with T2D. Our data suggest expectations may be informed by attitudes to insulin therapy, while perceived treatment benefits (e.g. weight-related benefits, administration frequency) may motivate uptake and ongoing use despite concerns. Experience of GLP-1RA injections may impact receptiveness to future insulin use.

Attitudes, Perceptions, and Practices in Managing Obesity Among Endocrinologists

OBJECTIVE

Obesity is globally recognized as a critically important disease by professional medical organizations in addition to the World Health Organization and American Medical Association, but the health care systems, medical teams, and the public have been slow to embrace this concept.

METHODS

American Association of Clinical Endocrinology (AACE) staff drafted the survey, and two endocrinologists independently reviewed the survey questions and modified the survey instrument. The survey included inquiries related to practice and patient demographics, awareness of obesity, treatment of obesity, barriers to improving obesity outcomes, digital health, cognitive behavioral therapy, lifestyle medicine, anti-obesity medications, weight stigma, and social determinants of health. The survey was emailed to 493 endocrinologists, with 305 completing the study (62%).

RESULTS

Ninety-eight percent of the responders agree that obesity is a disease, while 2% neither agree nor disagree. 53% of respondents are familiar with the term "adiposity-based chronic disease." 13% of the respondents are certified by the American Board of Obesity Medicine (ABOM). 57% of the respondents use published obesity guidelines as a resource for treating patients with obesity. Most endocrinologists recommend dietary and lifestyle changes, but fewer prescribe anti-obesity medication (AOM) or recommend bariatric surgery. ABOM-certified endocrinologists are more likely to use a multidisciplinary approach.

CONCLUSION

Self-reported knowledge and practices in the management of obesity highlight the importance of a multimodal approach to obesity and foster collaboration among healthcare professionals. It is necessary to raise awareness about obesity among clinicians, identify knowledge gaps and create educational tools to address those gaps.

Clinical Perspectives on the Use of Subcutaneous and Oral Formulations of Semaglutide

Early and effective glycemic control can prevent or delay the complications associated with type 2 diabetes (T2D). The benefits of glucagon-like peptide-1 receptor agonists (GLP-1RAs) are becoming increasingly recognized and they now feature prominently in international T2D treatment recommendations and guidelines across the disease continuum. However, despite providing effective glycemic control, weight loss, and a low risk of hypoglycemia, GLP-1RAs are currently underutilized in clinical practice. The long-acting GLP-1RA, semaglutide, is available for once-weekly injection and in a new once-daily oral formulation. Semaglutide is an advantageous choice for the treatment of T2D since it has greater efficacy in reducing glycated hemoglobin and body weight compared with other GLP-1RAs, has demonstrated benefits in reducing major adverse cardiovascular events, and has a favorable profile in special populations (e.g., patients with hepatic impairment or renal impairment). The oral formulation represents a useful option to help improve acceptance and adherence compared with injectable formulations for patients with a preference for oral therapy, and may lead to earlier and broader use of GLP-1RAs in the T2D treatment trajectory. Oral semaglutide should be taken on an empty stomach, which may influence the choice of formulation. As with most GLP-1RAs, initial dose escalation of semaglutide is required for both formulations to mitigate gastrointestinal adverse events. There are also specific dose instructions to follow with oral semaglutide to ensure sufficient gastric absorption. The evidence base surrounding the clinical use of semaglutide is being further expanded with trials investigating effects on diabetic retinopathy, cardiovascular outcomes, and on the common T2D comorbidities of obesity, chronic kidney disease, and non-alcoholic steatohepatitis. These will provide further information about whether the benefits of semaglutide extend to these other indications.

Psychosocial aspects and contributions of behavioural science to medication-taking for adults with type 2 diabetes

The aim of this narrative review was to determine the contribution of behavioural and psychosocial research to the field of medication-taking for adults with type 2 diabetes over the past 25 years. We review the behavioural and psychosocial literature relevant to adults with type 2 diabetes who are treated with oral antidiabetes agents, glucagon-like peptide-1 receptor agonists and insulin. Delayed uptake of, omission of and non-persistence with medications are significant problems among adults with type 2 diabetes. At each stage of the course of diabetes, during which medication to lower blood glucose is initiated or intensified, ~50% of people take less medication than prescribed. Research aimed at increasing optimal medication-taking behaviour has targeted 'forgetfulness', developing interventions which aid medication-taking, such as reminder devices, with limited success. In parallel, investigation of beliefs about medication has provided insights into the perceived necessity of and concerns about medication and how these inform medication-taking decisions. Guidance is available for health professionals to facilitate shared decision-making, particularly with insulin therapy; however, interventions addressing medication beliefs are limited. Optimal medication-taking behaviour is essential to prevent hyperglycaemia in adults with type 2 diabetes. Evidence from the past 25 years has demonstrated the association between medication beliefs and medication-taking behaviour. Health professionals need to address medication concerns, and establish and demonstrate the utility of diabetes medication with the individual within the clinical consultation. There are interventions that may assist diabetes health professionals in the shared decision-making process, but further development and more robust evaluation of these tools and techniques is required.

Assessing patient PREFERence between the dulaglutide pen and the semaglutide pen: A crossover study (PREFER)

AIM

When selecting treatments for type 2 diabetes (T2D), it is important to consider not only efficacy and safety, but also other treatment attributes that have an impact on patient preference. The objective of this study was to examine preference between injection devices used for two weekly GLP-1 receptor agonists.

MATERIALS AND METHODS

The PREFER study was an open-label, multicentre, randomized, crossover study assessing patient preference for dulaglutide and semaglutide injection devices among injection-naïve patients receiving oral medication for type 2 diabetes. After being trained to use each device, participants performed all steps of injection preparation and administered mock injections into an injection pad. Time-to-train (TTT) for each device was assessed in a subset.

RESULTS

There were 310 evaluable participants (48.4% female; mean age, 60.0 years; 78 participants in the TTT subgroup). More participants preferred the dulaglutide device than the semaglutide device (84.2% vs. 12.3%; P < 0.0001). More participants perceived the dulaglutide device to have greater ease of use (86.8% vs. 6.8%; P < 0.0001). After preparing and using the devices, more participants were willing to use the dulaglutide device (93.5%) than the semaglutide device (45.8%). Training participants to use the dulaglutide device required less time than the semaglutide device (3.38 vs. 8.14 minutes; P < 0.0001).

CONCLUSIONS

Participants with type 2 diabetes preferred the dulaglutide injection device to the semaglutide injection device. If patients prefer a device, they may be more willing to use the medication, which could result in better health outcomes. Furthermore, a shorter training time for injection devices may be helpful in busy clinical practice settings.

Timing of GLP-1 Receptor Agonist Initiation for Treatment of Type 2 Diabetes in the UK

Introduction

Patients with type 2 diabetes mellitus (T2DM) who fail to meet glycaemic control are at increased risk of diabetes complications. For patients who cannot maintain glycaemic control with oral medication, one recommended option is to add an injectable glucagon-like peptide-1 receptor agonist (GLP-1 RA) to their treatment regimen. The purpose of this study was to examine time to treatment intensification with GLP-1 RAs, including the duration of time that patients did not maintain glycaemic control with oral medication.

Methods

This was a medical record review conducted in the UK via a physician survey. Patients eligible to have their records reviewed were required to be ≥ 18 years of age, have a confirmed T2DM diagnosis, and have initiated GLP-1 RA treatment for T2DM in the past 6 months. All glycated haemoglobin (HbA1c) values within 5 years prior to GLP-1 RA initiation were collected.

Results

A total of 113 physicians contributed data for 1096 patients (mean age at the time of GLP-1 RA initiation was 54.9 years, 55.4% were male, and 71.4% were White). Median time from T2DM diagnosis to GLP-1 RA initiation was 6.1 years. Median consecutive time patients taking oral regimens were not under glycaemic control (HbA1c > 7.0%) prior to GLP-1 RA initiation was 13.5 months. Patients treated by general practitioners (GPs) had a significantly longer duration of time with insufficient glycaemic control prior to GLP-1 RA initiation compared with patients treated by diabetes specialists (median time for specialists was 11.0 months vs. 17.0 months for GPs; p = 0.038).

Conclusions

Results suggest that treatment intensification is often delayed despite consistently poor glycaemic control for more than 12 months, contrary to treatment guideline recommendations. Findings from this study highlight that some T2DM patients may benefit from more rapid treatment intensification, which could improve glycaemic control and reduce the risk for many short- and long-term health complications.

A Review of Practical Issues on the Use of Glucagon-Like Peptide-1 Receptor Agonists for the Management of Type 2 Diabetes

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are well established as effective treatments for patients with type 2 diabetes. GLP-1 RAs augment insulin secretion and suppress glucagon release via the stimulation of GLP-1 receptors. Although all GLP-1 RAs share the same underlying mechanism of action, they differ in terms of formulations, administration, injection devices and dosages. With six GLP-1 RAs currently available in Europe (namely, immediate-release exenatide, lixisenatide, liraglutide; prolonged-release exenatide, dulaglutide and semaglutide), each with its own characteristics and administration requirements, physicians caring for patients in their routine practice face the challenge of being cognizant of all this information so they are able to select the agent that is most suitable for their patient and use it in an efficient and optimal way. The objective of this review is to bring together practical information on the use of these GLP-1 RAs that reflects their approved use.Funding: Eli Lilly and Company.Plain Language Summary: Plain language summary available for this article.

Glucagon-Like Peptide 1 Receptor Agonists and the Risk of Incident Diabetic Retinopathy

OBJECTIVE

Previous studies suggested that glucagon-like peptide 1 receptor agonists (GLP-1 RAs) may initially worsen and possibly increase the risk of diabetic retinopathy. However, data on this possible association remain limited. Thus, this population-based study aimed to determine whether use of GLP-1 RAs is associated with an increased risk of incident diabetic retinopathy.

RESEARCH DESIGN AND METHODS

Using the U.K. Clinical Practice Research Datalink (CPRD), we conducted a cohort study among 77,115 patients with type 2 diabetes initiating antidiabetic drugs between January 2007 and September 2015. Adjusted hazard ratios (HRs) and 95% CIs of incident diabetic retinopathy were estimated using time-dependent Cox proportional hazards models, comparing use of GLP-1 RAs with current use of two or more oral antidiabetic drugs. In an ancillary analysis, new users of GLP-1 RAs were compared with new users of insulin.

RESULTS

During 245,825 person-years of follow-up, 10,763 patients were newly diagnosed with diabetic retinopathy. Compared with current use of two or more oral antidiabetic drugs, use of GLP-1 RAs was not associated with an increased risk of incident diabetic retinopathy overall (HR 1.00, 95% CI 0.85-1.17). Compared with insulin, GLP-1 RAs were associated with a decreased risk of diabetic retinopathy (HR 0.67, 95% CI 0.51-0.90).

CONCLUSIONS

The associations with diabetic retinopathy varied according to the type of comparator. When compared with use of two or more oral antidiabetic drugs, use of GLP-1 RAs was not associated with an increased risk of incident diabetic retinopathy. The apparent lower risk of diabetic retinopathy associated with GLP-1 RAs compared with insulin may be due to residual confounding.

Dulaglutide in the treatment of adult type 2 diabetes: a perspective for primary care providers

Approximately 90% of T2D patients in the US are diagnosed and treated in the primary care setting, and the majority of the burden of disease management falls to primary care providers. Here, we discuss the clinical data for once weekly dulaglutide, e.g. the results of seven completed Phase 3 trials, patient preference studies, patient reported outcomes (PRO), and clinical data surrounding the dulaglutide administration device. Dulaglutide 1.5 mg once weekly demonstrated superiority to placebo, metformin, sitagliptin, exenatide BID, and insulin glargine (in 2 trials), and non-inferiority to liraglutide in reduction of HbA1c from baseline, with an acceptable safety profile. Dulaglutide-treated patients achieved the composite endpoint of an HbA1c <7.0% with no hypoglycemia, no severe hypoglycemia, and no weight gain significantly more than metformin, sitagliptin, exenatide BID or insulin glargine treated patients. Dulaglutide consistently showed an early onset of glycemic control, lasting up to 104 weeks. Additionally, PRO and patient preference data support the benefit of once weekly dulaglutide for the treatment of T2D.

Characteristics of patients with type 2 diabetes mellitus newly treated with GLP-1 receptor agonists (CHADIG Study): a cross-sectional multicentre study in Spain

OBJECTIVE

Several glucagon-like peptide-1 (GLP-1) receptor agonists (GLP-1Ra) have been made recently available in Spain for type 2 diabetes mellitus (DM2) treatment. There are no published data on the clinical and sociodemographic profile of patients initiating treatment with GLP-1Ra in Spain. Our objective was to understand these patients' characteristics in a real-world clinical practice setting.

DESIGN

Cross-sectional observational study.

SETTING

Spanish specialist outpatient clinics.

PARTICIPANTS

403 adults with DM2 initiating GLP-1Ra treatment were included.

PRIMARY AND SECONDARY OUTCOME MEASURES

Sociodemographic and DM2-related clinical data, including treatment at and after GLP-1Ra initiation and comorbidities, were collected.

RESULTS

Evaluable patients (n=403; 50.9% female) were included (July 2013 to March 2014) at 24 centres by 53 specialists (47 endocrinology, 6 internal medicine), with the following profile (value±SD): age (58.3±10.4 years), diabetes duration (9.9±7 years), body mass index (BMI; 36.2±5.5) and glycated haemoglobin (HbA1c; 8.4±1.4%); 14% had HbA1c≤7%. Previous antidiabetic treatment: 53.8% only oral antidiabetic drugs (OADs), 5.2% insulin and 40% insulin and OAD; of those receiving OAD, 35% single drug, 38.2% 2 drugs and 24% 3 drugs. Concomitant to GLP-1Ra, 55.3% were only on OAD, 36.2% on insulin and OAD, and 7.2% only on insulin. Of those receiving OAD, the GLP-1Ra was mainly associated with 1 drug (65%) or 2 drugs (31.8%). GLP-1Ra are frequently added to existing antidiabetic drugs, with dipeptidyl peptidase-4 inhibitors being the OAD most frequently switched (45% receiving 1 before starting GLP-1Ra, only 2.7% receiving it concomitantly).

CONCLUSIONS

In Spain, GLP-1Ra therapy is usually started in combination with OADs or OADs and insulin. These drugs are used in relatively young patients often not reaching therapeutic goals with other treatment combinations, roughly a decade after diagnosis and with a relatively high BMI. The latter could be explained by Spanish regional payers limiting reimbursed prescription to patients with a minimum BMI threshold (>30 in most regions, >35 in some).
