Efficacy and safety of subgroup analysis stratified by baseline HbA1c in a Japanese phase 3 study of dulaglutide 0.75 mg compared with insulin glargine in patients with type 2 diabetes

An exploratory clinical trial on the efficacy and safety of glucagon-like peptide-1 receptor agonist dulaglutide in patients with type 2 diabetes on maintenance hemodialysis

Background

Dulaglutide is a once-weekly glucagon-like peptide-1 (GLP-1) receptor agonist approved for the treatment of type 2 diabetes mellitus (T2DM). However, the efficacy and safety of dulaglutide remain unclear in insulin-treated patients with T2DM on maintenance hemodialysis (HD).

Methods

Dulaglutide treatment was initiated, and the insulin dose was adjusted according to the needs of individual participants. Primary outcomes were changes in the mean and standard deviation (SD) of blood glucose (BG) levels and mean amplitude of glycemic excursions (MAGE) evaluated by continuous glucose monitoring (CGM) for six days, glycated albumin (GA), glycated hemoglobin (HbA1c), pre-dialysis blood glucose levels, and daily total insulin dose from the baseline over 24 weeks. Secondary outcomes were changes in treatment satisfaction and QOL levels from the baseline, measured by using the Diabetes Treatment Satisfaction Questionnaire (DTSQ) and the Diabetes Therapy-Related Quality of Life questionnaire (DTR-QOL) scores.

Results

The analysis was performed on the 12 participants who completed the study. The GA level (median − 1.8 [interquartile range − 6.6, − 0.3] %; p = 0.026) and daily total insulin dose (− 15.0 [− 24.5, − 9.4] U/day; p = 0.002) significantly decreased without increasing hypoglycemia (area over the glucose curve < 70 mg/dL: 0.0 [− 0.2, 0.0] mg·24 h/dl; p = 0.917). Four patients successfully withdrew from insulin therapy. The levels of HbA1c, SD of BG, and MAGE showed a decreasing tendency, but no significant improvement. Regarding treatment satisfaction and QOL, the total scores of DTSQ (8.0 [0.3, 12.5]; p = 0.041) and DTR-QOL (15.5 [− 1.8, 42.0]; p = 0.023) significantly improved.

Conclusion

Dulaglutide may help improve glycemic control, treatment satisfaction, and QOL without increasing hypoglycemia in insulin-treated patients with T2DM on maintenance HD.

Trial registration This study was registered with the University Hospital Medical Information Network-Clinical Trials Registry (UMIN-CTR) on October 11, 2016 (registration ID, UMIN000024283).

Efficacy and safety of dulaglutide compared with the first-line hypoglycemic drugs in Asian patients with type 2 diabetes: a systematic review and meta-analysis

To assess the efficacy and safety of dulaglutide in the treatment of Asian type 2 diabetes mellitus (T2DM), along with first-line hypoglycemic drugs. Systematic review and meta-analysis. Cochrane Library, Pubmed, Embase, and www.clinicaltrials.gov databases were searched from inception to September 27, 2022. The studies evaluating adults (≥ 18 years) undergoing dulaglutide (0.75 mg and 1.5 mg) and first-line hypoglycemic drugs were considered. There were only English languages. We used Stata 12.0 software to detect the risk of bias. 4 randomized controlled trials (RCTs), and 1 observational study. Both dulaglutide 0.75 mg dose group and 1.5 mg dose group could significantly reduce HbA1c [Dulaglutide 0.75 mg: WMD = - 0.20, 95% CI (- 0.28, - 0.11), P < 0.0001; Dulaglutide 1.5 mg: WMD = - 0.49, 95% CI (- 0.67, - 0.30), P < 0.0001] in Asian T2DM patients. In reducing fasting blood glucose (FBG) level, there was no significant difference observed in 2 dose groups. The body weight of patients in both dulaglutide dose groups was significantly reduced. In safety, the incidence of adverse events in the dulaglutide 0.75 mg dose group was slightly higher than that in the first-line drug group, but there was no statistically significant difference in the incidence of adverse events between the 1.5 mg dose group and the first-line drug group. Furthermore, the incidences of hypoglycemic events in both groups were higher than that in the first-line drug group. Two doses of dulaglutide showed better efficacy for Asian T2DM patients, but patients should be vigilant about the occurrence of hypoglycemia and gastrointestinal discomfort. However, more number and better quality of RCTs are suggested to confirm long-term safety and efficacy.

Effect of dulaglutide and long-acting insulin combination therapy in patients with type 2 diabetes: a retrospective observational study

Objective

The study aimed to evaluate the long-term effects of combination therapy comprising dulaglutide and long-acting insulin, on glycemic control in patients with type 2 diabetes.

Methods

This retrospective observational study included 20 patients with type 2 diabetes who underwent blood glucose management with intensive insulin therapy for a limited period. All patients were switched from intensive insulin therapy to combination therapy comprising dulaglutide and long-acting insulin. Hemoglobin A1c was evaluated before and 4, 12, and 24 weeks after starting combination therapy. Continuous glucose monitoring was conducted before and 1 and 24 weeks after starting combination therapy.

Results

Hemoglobin A1c levels were significantly reduced after 4, 12, and 24 weeks of combination therapy (- 2.2% ± 0.4%, P < 0.0001; - 3.7% ± 0.8%, P = 0.0003; and - 3.6% ± 0.8%, P = 0.0005, respectively). Glycemic variability (% coefficient of variation) was significantly decreased after 1 and 24 weeks of combination therapy (- 5.7% ± 2.1%, P = 0.011; and - 8.7% ± 2.4%, P = 0.003, respectively) and the percentage of readings and time > 250 mg/dL at 24 weeks was significantly improved (- 2.2% ± 0.8%, P = 0.019).

Conclusion

Combination therapy with dulaglutide and long-acting insulin resulted in better blood glucose control than intensive insulin therapy, which persisted for 24 weeks. Combination therapy also reduced blood glucose fluctuations and the number of self-injections needed.

Glycaemic Control in People with Diabetes Starting Treatment with Fast-Acting Insulin Aspart: a US Database Study

INTRODUCTION

This study investigated glycaemic control in individuals with type 1 (T1D) or type 2 diabetes (T2D) 6 months after initiating fast-acting insulin aspart (faster aspart) in a real-world setting.

METHODS

This was a single-arm, observational study using extracted patient data from the IBM^® Explorys^® database (USA) for individuals with T1D or T2D initiating faster aspart (at least one prescription of faster aspart) in the study period 1 January 2018 to 27 October 2020. Clinical characteristics, including age, body mass index, and baseline HbA1c, were extracted, as well as recorded events of hypoglycaemia. The primary endpoint was the change in HbA1c from baseline to 6 months.

RESULTS

A total of 787 individuals were included; 36.6% of these individuals had T1D and 63.4% had T2D (of whom 46.9% were new users of rapid-acting insulin when initiating faster aspart [T2D new users] and 53.1% were switching from another rapid-acting insulin to faster aspart [T2D switchers]). For individuals with T1D, T2D new users, or T2D switchers, estimated mean change in HbA1c from baseline to 6 months was - 0.20% (95% CI - 0.53, 0.14; p  =  0.252), - 1.00% (95% CI -  1.34, -  0.67; p < 0.0001), and - 0.70% (95% CI - 1.06,  - 0.35; p = 0.0001), respectively. In the baseline HbA1c > 8.5% subgroup, there was a significant estimated decrease in HbA1c from baseline to 6 months in individuals with T1D (-  1.2% [95% CI - 1.80,  -  0.60]; p = 0.0001) or T2D (- 0.6% [95% CI - 0.92, -  0.35]; p <  0.0001). Event rates of hypoglycaemia after 12 months were 0.68, 0.38, and 0.59 events/year for individuals with T1D, T2D new users, and T2D switchers, respectively.

CONCLUSION

US IBM^® Explorys^® data demonstrated a clinically relevant reduction in HbA1c 6 months after initiating faster aspart treatment for individuals with T2D, but not T1D overall, although patients with baseline HbA1c > 8.5% had significant HbA1c reductions regardless of diabetes type.

Switching from insulin to dulaglutide therapy in patients with type 2 diabetes: A real-world data study

AIM

Patients with type 2 diabetes (T2DM) who require injectable therapy have been conventionally treated with insulin. A glucagon-like peptide 1 receptor agonist was recently recommended as first-line injectable treatment, but few studies have investigated the effects of switching from insulin to dulaglutide. This study investigated the clinical efficacy and parameters affecting responses to dulaglutide as an alternative to insulin in patients with T2DM in a real-world clinical setting.

METHODS

Ninety-eight patients with T2DM who were switched from insulin to dulaglutide therapy were retrospectively evaluated. Changes in HbA1c concentrations were assessed after 6 months of consistent treatment with dulaglutide. Multiple linear regression analysis was performed to evaluate parameters affecting the response to dulaglutide treatment.

RESULTS

After treatment with dulaglutide for 6 months, patients experienced changes in HbA1c of -0.95% (95% confidence interval [CI]: -1.30% to -0.59%, P < 0.001) and in body weight of -1.75 kg (95% CI: -2.42 to -1.08 kg, P < 0.001). Multiple linear regression analysis showed that higher baseline HbA1c was significantly associated with a greater reduction in HbA1c. The most frequent adverse events were gastrointestinal symptoms.

CONCLUSION

Switching from insulin to dulaglutide can lead to significant improvement in HbA1c levels and body weight ​reduction in T2DM patients over 6 months. Higher baseline HbA1c is associated with a better clinical response to dulaglutide.

Dulaglutide improves glucocorticoid-induced hyperglycemia in inpatient care and reduces dose and injection frequency of insulin

BACKGROUND

Glucocorticoid (GC)-induced hyperglycemia is characterized by elevated postprandial blood glucose, which commonly requires multiple insulin injections. We investigated whether a long-acting glucagon-like peptide-1 receptor agonist, dulaglutide (Dula), safely improved GC-induced hyperglycemia in inpatients, to reduce insulin injection frequency.

METHODS

The data of hospitalized patients with GC-induced hyperglycemia treated with Dula (Dula group, n = 38) or without (non-Dula group, n = 38) were retrospectively evaluated. Baseline data were collected at the beginning of GC treatment. The primary outcome in this study was glycemic control, which was compared between the groups using the six-point blood glucose (before and 2 h after each meal) profiles at discharge. The daily injection frequency of injectable drugs at discharge were also compared between groups.

RESULTS

No specific trend of underlying diseases was observed between the non-Dula and Dula groups. The proportion of patients previously administered with GC pulse therapy was comparable between the two groups. No significant differences were observed between groups, in the starting maintenance GC dose, GC dose at pretreatment of Dula and discharge, and cumulative GC dose during the observation. Six-point blood glucose levels at pretreatment and discharge were comparable between the two groups. However, daily injection frequency of injectable drugs and insulin dose were significantly lower in the Dula group than that in the non-Dula group. No differences were observed in the number of hypoglycemic events, the elevation of serum pancreatic enzyme levels, or gastrointestinal adverse events.

CONCLUSION

These findings suggest that Dula could provide glycemic control while reducing the insulin dose and injection frequency in inpatients with GC-induced hyperglycemia. The occurrence of adverse events such as gastrointestinal symptoms and hypoglycemia did not increase in the Dula-treated patients compared to those not treated, suggesting its safety.

Clinical Efficacy and Parameters Affecting the Response to Dulaglutide Treatment in Patients with Type 2 Diabetes: A Retrospective, Real-World Data Study

INTRODUCTION

This study aimed to investigate the efficacy and clinical factors affecting the glycemic response to dulaglutide in type 2 diabetes (T2D) in a real-world clinical setting.

METHODS

We conducted a retrospective study of 234 patients at the Asan Medical Center, Republic of Korea, who had T2D and initiated dulaglutide from June 2016 to December 2017. The primary outcome was the change in glycated hemoglobin (HbA1c) concentration between baseline and 6 months after the initiation of therapy. Multivariate regression analysis was used to determine the clinical parameters contributing to a superior glycemic response to dulaglutide.

RESULTS

The mean age of the patients was 53, and 50% were male. Their mean baseline HbA1c, body mass index and duration of diabetes were 8.8%, 27.6 kg/m² and 10.2 years, respectively. The change in HbA1c between baseline and 6 months was - 0.92% (95% CI: - 1.1% to - 0.74%, p < 0.001). The reduction in body weight over the same period was -2.1 kg (95% CI: - 2.9 to - 1.3 kg, p < 0.001). Using multivariate regression analysis, baseline HbA1c was found to be a significant predictor of superior glycemic response to dulaglutide.

CONCLUSION

The use of dulaglutide was associated with a significant reduction in HbA1c and body weight over a 6-month period in a real-world clinical setting. T2D patients with higher baseline HbA1c concentrations were more likely to demonstrate good clinical responses to dulaglutide.

Use of Insulin Glargine 100 U/mL for the Treatment of Type 2 Diabetes Mellitus in East Asians: A Review

Insulin glargine (IGlar) 100 U/mL (IGlar-100) is widely used in East Asian countries for the treatment of type 2 diabetes mellitus (T2DM) and is the gold standard of basal insulin treatment. In this review we summarize key information about clinical experience with IGlar-100 in East Asian patients with T2DM, including findings from clinical trials and postmarketing studies. We also provide recommendations and opinions on the optimal use of IGlar-100 in this population. The findings from the studies highlighted in our review indicate that IGlar-100 can be a suitable treatment option for East Asians with T2DM, from initial therapy in combination with oral antihyperglycemic medications through to different combinations and intensification models.

Dulaglutide as an Add-on to Insulin in Type 2 Diabetes; Clinical Efficacy and Parameters Affecting the Response in Real-World Practice

PURPOSE

For patients with type 2 diabetes (T2DM) who remain above their glycemic target on insulin therapy, a combination of insulin and a glucagon-like peptide 1 receptor agonist has been recommended. However, few studies have been conducted to determine the clinical efficacy and parameters affecting the response to this combination in a real-world setting. This study aimed to investigate the clinical efficacy and parameters affecting the glycemic response to dulaglutide as an add-on to insulin therapy for T2DM in a real-world clinical setting.

PATIENTS AND METHODS

A retrospective study was performed in 120 patients with T2DM who had initiated dulaglutide as an add-on to insulin therapy between January 2017 and December 2018. After 6 months of treatment, the change in glycated hemoglobin (HbA1c) was evaluated. Multiple linear regression analysis was used to determine the parameters affecting the therapeutic response to dulaglutide.

RESULTS

The mean age of the patients was 55.1 years and 57.5% were male. The mean baseline HbA1c, body mass index, and duration of diabetes were 9.1%, 27.5 kg/m², and 17.2 years, respectively. The change in HbA1c between baseline and 6 months was -0.97% (95% confidence interval [CI]: -1.28 to -0.66%, P<0.001), the change in body weight was -2.05 kg (95% CI: -2.93 to -1.17 kg, P<0.001), and the change in total daily insulin dose was -11.67 IU (95% CI: -14.55 to -8.78 IU, P<0.001). In multiple linear regression analysis, higher baseline HbA1c was associated with a greater reduction in HbA1c. The most frequent adverse events were gastrointestinal symptoms, but these were well-tolerated.

CONCLUSION

Dulaglutide treatment in combination with insulin resulted in a significant improvement in HbA1c and body weight over a 6-month period in a real-world clinical setting. Higher baseline HbA1c was associated with a good clinical response.
