The efficacy and safety of imeglimin as add-on therapy in patients with type 2 diabetes inadequately controlled with metformin monotherapy.

ABSTRACT: OBJECTIVE:A 12-week study assessed the efficacy and safety of a new oral antidiabetic agent, imeglimin, as add-on therapy in type 2 diabetes patients inadequately controlled with metformin alone. RESEARCH DESIGN AND METHODS:A total of 156 patients were randomized 1:1 to receive imeglimin (1,500 mg twice a day) or placebo added to a stable dose of metformin (1,500-2,000 mg/day). Change in A1C from baseline was the primary efficacy outcome; secondary outcomes included fasting plasma glucose (FPG) and proinsulin/insulin ratio. RESULTS:After 12 weeks, the placebo-subtracted decrease in A1C with metformin-imeglimin was -0.44% (P < 0.001). Metformin-imeglimin also significantly improved FPG and the proinsulin/insulin ratio from baseline (-0.91 mg/dL and -7.5, respectively) compared with metformin-placebo (0.36 mg/dL and 11.81). Metformin-imeglimin therapy was generally well-tolerated with a comparable safety profile to metformin-placebo. CONCLUSIONS:Addition of imeglimin to metformin improved glycemic control and offers potential as a new treatment for type 2 diabetes.

Project description:BackgroundManagement of type 2 diabetes with metformin often does not provide adequate glycemic control, thereby necessitating add-on treatment. In a 24-week clinical trial, dapagliflozin, an investigational sodium glucose cotransporter 2 inhibitor, improved glycemic control in patients inadequately controlled with metformin. The present study is an extension that was undertaken to evaluate dapagliflozin as long-term therapy in this population.MethodsThis was a long-term extension (total 102 weeks) of a 24-week phase 3, multicenter, randomized, placebo-controlled, double-blind, parallel-group trial. Patients were randomly assigned (1:1:1:1) to blinded daily treatment (placebo, or dapagliflozin 2.5 to 5, or 10 mg) plus open-label metformin (≥1,500 mg). The previously published primary endpoint was change from baseline in glycated hemoglobin (HbA1c) at 24 weeks. This paper reports the follow-up to week 102, with analysis of covariance model performed at 24 weeks with last observation carried forward; a repeated measures analysis was utilized to evaluate changes from baseline in HbA1c, fasting plasma glucose (FPG), and weight.ResultsA total of 546 patients were randomized to 1 of the 4 treatments. The completion rate for the 78-week double-blind extension period was lower for the placebo group (63.5%) than for the dapagliflozin groups (68.3% to 79.8%). At week 102, mean changes from baseline HbA1c (8.06%) were +0.02% for placebo compared with -0.48% (P = 0.0008), -0.58% (P <0.0001), and -0.78% (P <0.0001) for dapagliflozin 2.5 to 5, and 10 mg, respectively. In addition, all dapagliflozin groups had sustained reductions from baseline in FPG (-1.07 to -1.47 mmol/l) and body weight (-1.10 to -1.74 kg) at 102 weeks, whereas increases were noted in placebo-treated patients for both of these outcomes. Events of hypoglycemia were rare and were not severe. Evidence suggestive of genital infection was reported in 11.7% to 14.6% of dapagliflozin patients and 5.1% of placebo patients, with one related discontinuation (dapagliflozin 5 mg). Evidence suggestive of urinary tract infection was reported in 8.0% to 13.3% of dapagliflozin patients and 8.0% of placebo patients, with one related discontinuation (dapagliflozin 2.5 mg).ConclusionsDapagliflozin added to metformin for 102 weeks enabled sustained reductions in HbA1c, FPG, and weight without increased risk of hypoglycemia in patients with type 2 diabetes who were inadequately controlled on metformin alone.Trial registrationClinicalTrials.gov: NCT00528879.

Project description:IntroductionSulfonylureas (SU) are commonly used antihyperglycemic agents. VERTIS CV was the cardiovascular outcome study for the sodium-glucose cotransporter 2 inhibitor ertugliflozin. Enrollment of patients in VERTIS CV occurred in two sequential cohorts (Cohort 1 and Cohort 2).MethodsThis substudy assessed the efficacy and safety of adding ertugliflozin to SU monotherapy. The primary endpoint was the change in HbA1c from baseline at 18 weeks.ResultsAmong the 8246 patients who were randomized in VERTIS CV, 157 patients in Cohort 1 and 135 patients in Cohort 2 were on SU monotherapy at baseline. In the prespecified analysis (Cohort 1 only), the least squares (LS) mean HbA1c change from baseline for placebo, ertugliflozin 5 mg, and ertugliflozin 15 mg was - 0.56%, - 0.91%, and - 0.78%, respectively (placebo-adjusted LS mean [95% CI] change: - 0.35% [- 0.72%, 0.02%]; - 0.22% [- 0.60%, 0.16%] for ertugliflozin 5 and 15 mg, respectively; p > 0.05 for both). In a post-hoc analysis that included Cohorts 1 and 2 (N = 292), the LS mean HbA1c change from baseline at week 18 for placebo, ertugliflozin 5 mg, and ertugliflozin 15 mg was - 0.31%, - 0.77%, and - 0.68%, respectively (placebo-adjusted change: - 0.46% [- 0.73%, - 0.18%]; - 0.37% [- 0.66%, - 0.09%]; p = 0.001 and 0.01 for ertugliflozin 5 and 15 mg, respectively). In Cohort 1, adverse events were reported in 45.8%, 47.3%, and 25.9% of patients with placebo, ertugliflozin 5 mg, and ertugliflozin 15 mg. The incidence rates of symptomatic hypoglycemia were 0.0%, 5.5%, and 3.7%, respectively, with no cases of severe hypoglycemia. The safety profile was similar for Cohorts 1 and 2 combined.ConclusionThe addition of ertugliflozin to SU monotherapy reduced HbA1c but did not result in significant placebo-adjusted reductions from baseline according to the prespecified primary analysis (n = 157); however, in a post-hoc analysis with a larger patient population (n = 292), significant and clinically relevant HbA1c reductions were observed. Ertugliflozin was generally well tolerated.Trial registrationClinicalTrials.gov identifier: NCT01986881.

Project description:Objective: We assessed the efficacy, safety, and tolerability of cannabidivarin (CBDV) as add-on therapy in adults with inadequately controlled focal seizures. Materials and Methods: One hundred and sixty-two participants (CBDV n=81; placebo n=81) were enrolled. After a 4-week baseline, participants titrated from 400 to 800 mg CBDV twice daily (b.i.d.) (or placebo) over 2 weeks, followed by 6 weeks stable dosing (at 800 mg b.i.d.) and a 12-day taper period. The primary endpoint was the change from baseline in focal seizure frequency during the 8-week treatment period. Secondary endpoints included additional efficacy measures relating to seizures, physician- and participant-reported outcomes, change in the use of rescue medication, cognitive assessments, and safety. Results: Median baseline focal seizure frequencies were 17-18 per 28 days in both groups, and similar reductions in frequency were observed in the CBDV (40.5%) and placebo (37.7%) groups during the treatment period (treatment ratio [% reduction] CBDV/placebo: 0.95 [4.6]; confidence interval: 0.78-1.17 [-16.7 to 21.9]; p=0.648). There were no differences between the CBDV and placebo groups for any seizure subtype. There were no significant treatment differences between CBDV and placebo groups for any of the secondary efficacy outcome measures. Overall, 59 (72.8%) of participants in the CBDV group and 39 (48.1%) in the placebo group had ≥1 treatment-emergent adverse event (AE); the 3 most common were diarrhea, nausea, and somnolence. The incidence of serious AEs was low (3.7% in the CBDV group vs. 1.2% in the placebo group). There was little or no effect of CBDV on vital signs, physical examination, or electrocardiogram findings. Elevations in serum transaminases (alanine aminotransferase or aspartate aminotransferase) to levels >3×upper limit of normal occurred in three participants taking CBDV (two discontinued as a result) and one taking placebo; however, none met the criteria for potential Hy's Law cases. Conclusion: It is likely the 40.5% seizure reduction with CBDV represents an appropriate pharmacological response in this population with focal seizures. The placebo response was, however, high, which may reflect the participants' expectations of CBDV, and a treatment difference from placebo was not observed. CBDV was generally well tolerated.

Project description:ObjectiveTo examine the efficacy and safety of lixisenatide (20 μg once daily, administered before the morning or evening meal) as add-on therapy in patients with type 2 diabetes insufficiently controlled with metformin alone.Research design and methodsThis was a 24-week, randomized, double-blind, placebo-controlled study in 680 patients with inadequately controlled type 2 diabetes (HbA1c 7-10% [53-86 mmol/mol]). Patients were randomized to lixisenatide morning (n = 255), lixisenatide evening (n = 255), placebo morning (n = 85), or placebo evening (n = 85) injections.ResultsLixisenatide morning injection significantly reduced mean HbA1c versus combined placebo (mean change -0.9% [9.8 mmol/mol] vs. -0.4% [4.4 mmol/mol]; least squares [LS] mean difference vs. placebo -0.5% [5.5 mmol/mol], P < 0.0001). HbA1c was significantly reduced by lixisenatide evening injection (mean change -0.8% [8.7 mmol/mol] vs. -0.4% [4.4 mmol/mol]; LS mean difference -0.4% [4.4 mmol/mol], P < 0.0001). Lixisenatide morning injection significantly reduced 2-h postprandial glucose versus morning placebo (mean change -5.9 vs. -1.4 mmol/L; LS mean difference -4.5 mmol/L, P < 0.0001). LS mean difference in fasting plasma glucose was significant in both morning (-0.9 mmol/L, P < 0.0001) and evening (-0.6 mmol/L, P = 0.0046) groups versus placebo. Mean body weight decreased to a similar extent in all groups. Rates of adverse events were 69.4% in both lixisenatide groups and 60.0% in the placebo group. Rates for nausea and vomiting were 22.7 and 9.4% for lixisenatide morning and 21.2 and 13.3% for lixisenatide evening versus 7.6 and 2.9% for placebo, respectively. Symptomatic hypoglycemia occurred in 6, 13, and 1 patient for lixisenatide morning, evening, and placebo, respectively, with no severe episodes.ConclusionsIn patients with type 2 diabetes inadequately controlled on metformin, lixisenatide 20 μg once daily administered in the morning or evening significantly improved glycemic control, with a pronounced postprandial effect, and was well tolerated.
