Efficacy and safety of trelagliptin in combination with insulin therapy in Japanese patients with type 2 diabetes: Results from a randomized, Phase IV study.

ABSTRACT: We aimed to explore the efficacy and safety of once-weekly trelagliptin 100 mg as an add-on therapy to insulin in Japanese patients with type 2 diabetes mellitus with inadequate glycaemic control. Patients with haemoglobin A1c (HbA1c) 7.5% to 10.0% who were receiving 8 to 40 units of insulin per day were randomized to receive, with insulin, trelagliptin 100 mg (A/A, n = 116) or placebo (P/A, n = 124) for a 12-week double-blind (DB) phase, after which all received trelagliptin for a 40-week open-label phase. Primary endpoints were HbA1c change from baseline to the end of the DB phase and adverse events (AEs). HbA1c significantly decreased in the A/A group vs the P/A group at the end of the DB phase (least square mean difference, -0.63% [95% CI, -0.83 to -0.44]: P < .0001). The frequency of treatment-emergent AEs during the DB phase was 44.0% in the A/A group and 47.6% in the P/A group. No patient experienced severe hypoglycaemia during trelagliptin treatment. Once-weekly trelagliptin 100 mg therapy with insulin demonstrated a significant reduction in HbA1c. Long-term treatment was well-tolerated, with no clinically significant hypoglycaemia, suggesting that trelagliptin with insulin is a meaningful treatment option in this patient population.

Project description:Combination therapy with canagliflozin and insulin was investigated in a prescribed substudy of the canagliflozin Cardiovascular Assessment Study (CANVAS); however, it was not evaluated in Japanese patients with type 2 diabetes mellitus (T2DM). Since the usage profile of insulin therapy and pathologic features of Japanese patients differ from those of Caucasian patients, we determined the clinical benefit of such a combination therapy in Japanese patients.Patients who had inadequate glycemic control despite insulin, diet and exercise therapies were randomized into placebo (n = 70) and canagliflozin 100 mg (n = 76) groups that were administered once daily in addition to their prior insulin therapy in this double-blind, placebo-controlled study. The primary endpoint was the change in glycated hemoglobin (HbA1c) levels from the baseline to week 16.There was a statistically significant decrease in HbA1c levels from the baseline in the canagliflozin group (-0.97 ± 0.08 %) compared with the placebo group (0.13 ± 0.08 %) at week 16 [last observation carried forward (LOCF)]. The decrease in HbA1c levels in the canagliflozin group was independent of the insulin regimen (premixed, long-acting and long-acting plus rapid- or short-acting). Compared with the placebo group, canagliflozin significantly decreased fasting plasma glucose levels (-34.1 ± 4.8 vs -1.4 ± 5.0 mg/dL) and body weights (-2.13 ± 0.25 vs 0.24 ± 0.26 %), and significantly increased HDL cholesterol (3.3 ± 1.0 vs -0.5 ± 1.0 mg/dL) and HOMA2- %B (10.15 ± 1.37 vs 0.88 ± 1.42 %). The overall incidence of adverse events was similar between the two groups. The incidence and incidence per subject-year exposure of hypoglycemia (hypoglycemic symptoms and/or decreased blood glucose) were slightly higher in the canagliflozin group (40.0 % and 7.97) than in the placebo group (29.6 % and 4.51). However, hypoglycemic events in both groups were mild in severity and dose-reduction of insulin by <10 % from the baseline following hypoglycemic events decreased the incidence per subject-year exposure in the canagliflozin group. The incidence of hypoglycemia between the groups did not differ according to the insulin regimen.Canagliflozin in combination with insulin was effective in improving glycemic control and reducing body weight and well tolerated by Japanese patients with T2DM.

Project description:IntroductionAlthough global studies have investigated the combination of dulaglutide with insulin in patients with type 2 diabetes mellitus (T2DM), differences in lean body mass and dulaglutide dosing can complicate the extrapolation of global study results to Japanese patients. This phase 4, randomized, placebo-controlled, double-blind, and subsequent open-label study aimed to assess the efficacy and safety of once-weekly dulaglutide 0.75 mg in combination with insulin therapy in patients with T2DM.MethodsPatients enrolled in this multicenter study were Japanese with T2DM who had inadequate glycemic control (HbA1c 7.5-10.5%) with insulin therapy (basal insulin, premixed insulin, or basal/mealtime insulin) in combination with or without one or two oral antidiabetic agents (OADs). Patients were randomized in a 3:1 ratio to dulaglutide or placebo. The first 16 weeks was the double-blind period with stable insulin dosing, and patients taking placebo were switched to dulaglutide for an additional 36-week open-label period in which all patients took dulaglutide (52 weeks total).ResultsPatients (N = 159) were randomized to dulaglutide (n = 120) or placebo (n = 39). The least-squares (LS) mean changes from baseline in HbA1c at week 16 were dulaglutide - 1.45% and placebo 0.06%. The LS mean and 95% confidence interval for the difference were - 1.50% (- 1.73%, - 1.28%) and dulaglutide was superior to placebo. There were no significant differences between treatment groups in changes from baseline in body weight and insulin dose. The most frequently observed treatment-emergent adverse events in dulaglutide were nasopharyngitis, constipation, abdominal discomfort, nausea, and decreased appetite. The incidence rates of hypoglycemic events by week 16 were dulaglutide 42.5% and placebo 30.8% (P = 0.258).ConclusionOnce-weekly dulaglutide 0.75 mg was superior to once-weekly placebo in glycemic control improvement and well tolerated in patients with T2DM in combination with insulin therapy with or without OADs.Trial registrationClinicalTrials.gov, NCT02750410.FundingEli Lilly and Company.

Project description:INTRODUCTION:This study assessed the efficacy and safety of insulin glargine 300?U/mL (Gla-300) during hospitalization and therapy intensification at discharge in insufficiently controlled people with type 2 diabetes. RESEARCH DESIGN AND METHODS:COBALTA (for its acronym in Spanish, COntrol Basal durante la hospitalizacion y al ALTA) was a multicenter, open-label, single-arm, phase IV trial including 112 evaluable inpatients with type 2 diabetes insufficiently controlled (glycosylated hemoglobin (HbA1c) 8%-10%) with basal insulin and/or non-insulin antidiabetic drugs. Patients were treated with a basal-bolus-correction insulin regimen with Gla-300 during the hospitalization and with Gla-300 and/or non-insulin antidiabetics for 6 months after discharge. The primary endpoint was the HbA1c change from baseline to month 6 postdischarge. RESULTS:HbA1c levels decreased from 8.8%±0.6% at baseline to 7.2%±1.1% at month 6 postdischarge (p<0.001, mean change 1.6%±1.1%). All 7-point blood glucose levels decreased from baseline to 24?hours predischarge (p?0.001, mean changes from 25.1±66.6?to 63.0±85.4?mg/dL). Fasting plasma glucose also decreased from baseline to 24?hours predischarge (p<0.001), month 3 (p<0.001) and month 6 (p<0.001) postdischarge (mean changes 51.5±90.9, 68.2±96.0?and 77.6±86.4?mg/dL, respectively). Satisfaction was high and hyperglycemia/hypoglycemia perception was low according to the Diabetes Treatment Satisfaction Questionnaire at month 6 postdischarge. The incidence of confirmed (glucose<70?mg/dL)/severe hypoglycemia was 25.0% during hospitalization and 59.1% 6 months after discharge. No safety concerns were reported. CONCLUSIONS:Inpatient and intensification therapy at discharge with Gla-300 improved significantly glycemic control of patients with type 2 diabetes insufficiently controlled with other basal insulin and/or non-insulin antidiabetic medication, with high treatment satisfaction. Gla-300 could therefore be a treatment choice for hospital and postdischarge diabetes management.
