Efficacy and Safety of Dulaglutide 3.0 mg and 4.5 mg Versus Dulaglutide 1.5 mg in Metformin-Treated Patients With Type 2 Diabetes in a Randomized Controlled Trial (AWARD-11).

ABSTRACT:

Objective

To compare efficacy and safety of dulaglutide at doses of 3.0 and 4.5 mg versus 1.5 mg in patients with type 2 diabetes inadequately controlled with metformin.

Research design and methods

Patients were randomly assigned to once-weekly dulaglutide 1.5 mg, 3.0 mg, or 4.5 mg for 52 weeks. The primary objective was determining superiority of dulaglutide 3.0 mg and/or 4.5 mg over 1.5 mg in HbA_1c reduction at 36 weeks. Secondary superiority objectives included change in body weight. Two estimands addressed efficacy objectives: treatment regimen (regardless of treatment discontinuation or rescue medication) and efficacy (on treatment without rescue medication) in all randomly assigned patients.

Results

Mean baseline HbA_1c and BMI in randomly assigned patients (N = 1,842) was 8.6% (70 mmol/mol) and 34.2 kg/m², respectively. At 36 weeks, dulaglutide 4.5 mg provided superior HbA_1c reductions compared with 1.5 mg (treatment-regimen estimand: -1.77 vs. -1.54% [-19.4 vs. -16.8 mmol/mol], estimated treatment difference [ETD] -0.24% (-2.6 mmol/mol), P < 0.001; efficacy estimand: -1.87 vs. -1.53% [-20.4 vs. -16.7 mmol/mol], ETD -0.34% (-3.7 mmol/mol), P < 0.001). Dulaglutide 3.0 mg was superior to 1.5 mg for reducing HbA_1c, using the efficacy estimand (ETD -0.17% [-1.9 mmol/mol]; P = 0.003) but not the treatment-regimen estimand (ETD -0.10% [-1.1 mmol/mol]; P = 0.096). Dulaglutide 4.5 mg was superior to 1.5 mg for weight loss at 36 weeks for both estimands (treatment regimen: -4.6 vs. -3.0 kg, ETD -1.6 kg, P < 0.001; efficacy: -4.7 vs. -3.1 kg, ETD -1.6 kg, P < 0.001). Common adverse events through 36 weeks included nausea (1.5 mg, 13.4%; 3 mg, 15.6%; 4.5 mg, 16.4%) and vomiting (1.5 mg, 5.6%; 3 mg, 8.3%; 4.5 mg, 9.3%).

Conclusions

In patients with type 2 diabetes inadequately controlled by metformin, escalation from dulaglutide 1.5 mg to 3.0 mg or 4.5 mg provided clinically relevant, dose-related reductions in HbA_1c and body weight with a similar safety profile.

Project description:INTRODUCTION:This analysis evaluated the efficacy and safety of dulaglutide in Chinese patients with type 2 diabetes (T2D) aged ??60 and <?60 years. METHODS:This post hoc analysis included patients with T2D enrolled in two phase 3 clinical trials AWARD-CHN1 (NCT01644500) and AWARD-CHN2 (NCT01648582) of dulaglutide 0.75 and 1.5 mg. Patients were categorized into two groups (??60 and <?60 years). Efficacy outcomes (change in glycated hemoglobin [HbA1c], fasting blood glucose [FBG], and weight; percentage of patients achieving HbA1c target [<?7.0%]) and safety outcomes (incidence of hypoglycemia and gastrointestinal treatment-emergent adverse events [GI TEAEs]) at 26 weeks were evaluated for each age group in both trials. RESULTS:A total of 766 patients (??60 years, n?=?222;?<?60 years, n?=?544) were included in the study. A similar reduction of HbA1c was observed in both age groups: AWARD-CHN1, 1.5 mg (least squares mean [LSM] 95% confidence interval [CI] ??60 years: -?1.45% [-?1.69, -?1.21%] and <?60 years: -?1.43% [-?1.59, -?1.28%]) and 0.75 mg (??60 years: -?1.29% [-?1.53, -?1.05%] and <?60 years: -?1.18% [-?1.33, -?1.03%]); AWARD-CHN2, 1.5 mg (??60 years: -?1.60% [-?1.83, -?1.36%] and <?60 years: -?1.64% [-?1.80, -?1.49%]) and 0.75 mg (??60 years: -?1.31% [-?1.55, -?1.08%] and <?60 years: -?1.33% [-?1.48, -?1.17%]). Dulaglutide showed a reduction in HbA1c as early as 4 weeks after initiation of treatment, which was maintained over 26 weeks in both age groups. The percentage of patients achieving HbA1c target?<?7.0% at 26 weeks was also similar in both age groups. Incidence of hypoglycemia and GI TEAEs was low in each age group. CONCLUSION:Treatment with once-weekly dulaglutide improved glycemic control in patients with T2D aged ??60 years and <?60 years and was well tolerated in older patients, suggesting it can be considered a safe and effective treatment option for use in older patients with T2D. TRIAL REGISTRATION:AWARD-CHN1 (NCT01644500) and AWARD-CHN2 (NCT01648582).

Project description:AimsLiraglutide, a GLP-1 receptor agonist, regulates appetite via receptors in the brain. Because of concerns regarding the potential of centrally-acting anti-obesity medications to affect mental health, pooled neuropsychiatric safety data from all phase 2 and 3a randomized, double-blind trials with liraglutide 3.0?mg were evaluated post hoc.MethodsData from the liraglutide weight-management programme were pooled. Across trials, individuals with a body mass index ?30 or ?27?kg/m2 with weight-related comorbidities were randomized to once-daily subcutaneous liraglutide 3.0?mg (n?=?3384) or placebo (n?=?1941), both with a 500?kcal/d deficit diet, plus exercise. Adverse events related to neuropsychiatric safety were collected in all trials. Additionally, in the phase 3a trials, validated mental-health questionnaires were prospectively and systematically administered.ResultsIn the pooled analysis of 5325 randomized and exposed individuals, rates of depression (2.1 vs 2.1 events/100 person-years) and anxiety (1.9 vs 1.7 events/100 person-years) through adverse event reporting were similarly low in liraglutide and placebo groups. Nine (0.3%) individuals receiving liraglutide and 2 (0.1%) receiving placebo reported adverse events of suicidal ideation or behaviour. In phase 3a trials, mean baseline Patient Health Questionnaire-9 scores of 2.8?±?3.0 vs 2.9?±?3.1 for liraglutide vs placebo improved to 1.8?±?2.7 vs 1.9?±?2.7, respectively, at treatment end; 34/3291 individuals (1.0%) receiving liraglutide 3.0?mg vs 19/1843 (1.0%) receiving placebo reported suicidal ideation on the Columbia-Suicide Severity Rating Scale.ConclusionsResults of this exploratory pooled analysis provide no cause for concern regarding the neuropsychiatric safety of treatment with liraglutide 3.0?mg in patients similar to those included in the examined trials. Although there was a small numerical imbalance in suicidal ideation with liraglutide through adverse event reporting, no between-treatment imbalances in suicidal ideation/behaviour or depression were noted through prospective questionnaire assessments.
