Efficacy and safety of dulaglutide 3.0 and 4.5 mg in patients aged younger than 65 and 65 years or older: Post hoc analysis of the AWARD-11 trial.

ABSTRACT:

Aim

To evaluate the efficacy and safety of dulaglutide 3.0 and 4.5 mg versus 1.5 mg when used as an add-on to metformin in subgroups defined by age (<65 and ≥65 years).

Materials and methods

Of 1842 patients included in this post hoc analysis, 438 were aged 65 years or older and 1404 were younger than 65 years. The intent-to-treat (ITT) population, while on treatment without rescue medication, was used for all efficacy analyses; the ITT population without rescue medication was used for hypoglycaemia analyses; all other safety analyses used the ITT population.

Results

Patients aged 65 years or older and those younger than 65 years had a mean age of 69.5 and 53.2 years, respectively. In each age subgroup, the reduction from baseline in HbA1c and body weight (BW), and the proportion of patients achieving a composite endpoint of HbA1c of less than 7% (<53 mmol/mol) with no weight gain and no documented symptomatic or severe hypoglycaemia, were larger for dulaglutide 3.0 and 4.5 mg compared with dulaglutide 1.5 mg, but the treatment-by-age interactions were not significant. The safety profile for the additional dulaglutide doses was consistent with that of dulaglutide 1.5 mg and was similar between the age subgroups.

Conclusion

Dulaglutide doses of 3.0 or 4.5 mg provided clinically relevant, dose-related improvements in HbA1c and BW with no significant treatment-by-age interactions, and with a similar safety profile across age subgroups.

Project description:ObjectiveTo 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 methodsPatients 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 HbA1c 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.ResultsMean baseline HbA1c 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 HbA1c 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 HbA1c, 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%).ConclusionsIn 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 HbA1c 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:IntroductionWe evaluated the effect of dulaglutide on the relative contributions of fasting glucose (FG) and postprandial glucose (PPG) to overall hyperglycemia in patients with type 2 diabetes (T2D), and assessed responses to dulaglutide versus insulin glargine (glargine) in patients with different baseline glycemic patterns.MethodsThis post-hoc analysis of the phase 3 AWARD-CHN2 trial included data from 560 Chinese patients with uncontrolled T2D who received once-weekly dulaglutide (1.5 or 0.75 mg) or once-daily glargine for 26 weeks. The relative contributions of FG and PPG to overall hyperglycemia across different glycated hemoglobin (HbA1c) categories were calculated using the area under the curve of 7-point self-monitored blood glucose profiles. Patients were also categorized into four subgroups according to median baseline FG (cutoff 8.9 mmol/L) and PPG (cutoff 12.5 mmol/L): low FG/low PPG, low FG/high PPG, high FG/low PPG and high FG/high PPG. Changes in glycemic parameters and body weight were calculated for patients in each subgroup.ResultsAmong patients receiving dulaglutide, higher HbA1c was associated with higher relative contributions of FG and lower relative contributions of PPG to overall hyperglycemia at baseline and week 26 of dulaglutide treatment. After 26 weeks, dulaglutide 1.5 mg led to statistically greater decreases in HbA1c from baseline versus glargine in most subgroups, including the high FG subgroups, and a numerically greater decrease in HbA1c was observed in the low FG/high PPG subgroup. Across all subgroups, higher proportions of patients achieved HbA1c ≤ 6.5% with dulaglutide 1.5 mg than with glargine (all P < 0.05). Dulaglutide 1.5 mg showed better control of body weight than glargine in all subgroups (all P < 0.05).ConclusionsDulaglutide reduced HbA1c through reductions in both FG and PPG across HbA1c categories in T2D patients with uncontrolled hyperglycemia. Furthermore, treatment with dulaglutide provided a greater reduction in HbA1c than glargine, regardless of baseline FG and PPG levels.
