Safety and Efficacy of Teneligliptin in Patients with Type 2 Diabetes Mellitus and Impaired Renal Function: Interim Report from Post-marketing Surveillance.

ABSTRACT: INTRODUCTION:Teneligliptin is a novel oral dipeptidyl peptidase-4 inhibitor for the treatment of type 2 diabetes mellitus (T2DM). Safety and efficacy of teneligliptin have been demonstrated in clinical studies; however, data supporting its use in patients with moderate or severe renal impairment are limited. This interim analysis of a post-marketing surveillance of teneligliptin, exploRing the long-term efficacy and safety included cardiovascUlar events in patients with type 2 diaBetes treated bY teneligliptin in the real-world (RUBY), aims to verify the long-term safety and efficacy of teneligliptin in Japanese patients with T2DM and impaired renal function. METHODS:For this analysis, we used the data from case report forms of the RUBY surveillance between May 2013 and June 2017. The patients were classified into G1-G5 stages of chronic kidney disease according to estimated glomerular filtration rate (eGFR) at initiation of teneligliptin treatment. Safety and efficacy were evaluated in these subgroups. Patients on dialysis were also assessed. Safety was assessed from adverse drug reactions (ADRs). Glycemic control was evaluated up to 2 years after teneligliptin initiation. RESULTS:A total of 11,677 patients were enrolled in the surveillance and 11,425 patient case-report forms were collected for the interim analysis. The incidence of ADRs in each subgroup was 2.98-6.98% of patients, with no differences in the ADR profile (including hypoglycemia and renal function ADRs) between subgroups. At 1 and 2 years after starting teneligliptin, the least-squares mean change in HbA1c adjusted to the baseline was - 0.68 to - 0.85% and - 0.71 to - 0.85% across the eGFR groups, respectively. Treatment with teneligliptin in patients on dialysis reduced or tended to reduce glycated albumin levels [- 2.29%, (p < 0.001) after 1 year; - 1.64%, (p = 0.064) after 2 years]. CONCLUSIONS:During long-term treatment, teneligliptin was generally well tolerated in patients with any stage of renal impairment from normal to end-stage renal disease, including those on dialysis, and improved glycemic control.

Project description:IntroductionDolutegravir (DTG), a novel HIV-integrase strand transfer inhibitor (INSTI), is usually used with multiple antiretrovirals (ARVs) for treatment of HIV. DTG is now approved as Tivicay tablets in over 120 countries and Triumeq combination tablets (DTG/abacavir [ABC]/lamivudine [3TC]) in over 90 countries. In Japan, these formulations have been marketed since 2014 and 2015. The post-marketing prospective surveillance has been conducted as part of the HIV-Related Drug (HRD) cooperative survey aimed to collect actual drug use information in all of these DTG-treated patients in accordance with conditions for initial approvals.MethodsThe survey has been conducted to evaluate long-term safety and effectiveness of DTG since 2014, for approximately 6 years. The safety was evaluated by incidence of adverse drug reactions (ADRs) and change in body weight. The effectiveness was evaluated by plasma HIV RNA copies/mL and peripheral CD4+ cell counts.ResultsOf 2292 patients in 30 Japanese sites, 565 (24.65%) reported ADRs. The most common ADR was blood creatinine increased (4.28%). Incidence of ADRs was statistically significantly higher in patients with severe symptoms (Centers for Disease Control and Prevention [CDC] categories B and C) than those with category A, and in patients with comorbidities than those without comorbidities. Whereas incidence of ADRs was statistically significantly lower in antiretroviral therapy (ART)-experienced patients than that in ART-naïve patients. Incidence of ADRs related to suicide or self-injurious behavior was statistically significantly higher in patients with comorbidities of psychiatric disorders than those without comorbidities. The body weight tended to increase over time and those changes and percentage changes from baseline were greater in ART-naïve patients compared with ART-experienced patients. HIV RNA copies/mL and CD4+ cell counts showed favorable shifts from baseline in both ART-naïve and ART-experienced patients.ConclusionThe results of the survey identified no new safety and effectiveness risks in Japanese patients with HIV/AIDS treated with DTG.

Project description:IntroductionHealthy eating is a critical aspect of the prevention and management of type 2 diabetes (T2DM). Disrupted eating patterns can result in poor glucose control and increase the likelihood of diabetic complications. Teneligliptin inhibits dipeptidyl peptidase-4 activity for 24 h and suppresses postprandial hyperglycemia after all three daily meals. This interim analysis of data from the large-scale post-marketing surveillance of teneligliptin (RUBY) in Japan examined eating patterns and their relationship with metabolic parameters and diabetic complications. We also examined whether eating patterns affected safety and efficacy of teneligliptin.MethodsWe analyzed baseline data from survey forms collected in RUBY between May 2013 and June 2017, including patient characteristics, metabolic parameters, and eating patterns (eating three meals per day or not; timing of evening meal) before teneligliptin treatment was initiated. Safety and efficacy of 12 months' teneligliptin (20-40 mg/day) treatment was assessed.ResultsData from 10,532 patients were available for analysis. Most patients who did not eat three meals per day (n =757) or who ate their evening meal after 10 PM (n =206) were 64 years old or younger. At baseline, glycated hemoglobin (HbA1c), fasting blood glucose, triglycerides, total and low-density lipoprotein cholesterol, body mass index, alanine aminotransferase, and aspartate aminotransferase levels were higher in those patients who did not eat three meals per day (p < 0.05) or who ate their evening meal late (p < 0.05). Diabetic complications were more common in patients who did not eat three meals per day. Treatment with teneligliptin reduced HbA1c over 6 or 12 months across all eating patterns, with a low incidence of adverse drug reactions.ConclusionsEating patterns may be associated with altered metabolic parameters and diabetic complications among Japanese patients with T2DM. Teneligliptin may be well tolerated and improve hyperglycemia in patients with T2DM irrespective of eating patterns.FundingMitsubishi Tanabe Pharma Corporation and Daiichi Sankyo Co.

Project description:IntroductionNintedanib is recommended for the treatment of idiopathic pulmonary fibrosis (IPF); however, treatment discontinuation due to adverse events (AEs) is common. A large-scale post-marketing surveillance study is investigating the real-world tolerability/safety of nintedanib in Japanese patients with IPF in routine clinical practice. Here, we report a 12-month interim analysis of this study.MethodsThe study included Japanese patients with IPF who started nintedanib between 31 August 2015 and 25 December 2018. The primary outcome was the frequency of adverse drug reactions (ADRs), defined as AEs for which a causal relationship with nintedanib could not be excluded. The secondary outcome was change from baseline in forced vital capacity (FVC). Outcomes were analysed in patients who stopped ('discontinued' subgroup) and continued ('continued' subgroup) nintedanib after 12 months. A multivariate analysis was performed to determine potential risk factors for treatment discontinuation.ResultsOf 5578 patients in the safety analysis set, 2795 (50.1%) discontinued nintedanib within 12 months of treatment initiation. Overall, 3767 patients (67.5%) had ADRs, with 1356 (24.3%) discontinuing nintedanib because of an ADR. Among patients in the 'discontinued' subgroup (n = 2795), 1442 (51.6%) discontinued because of an ADR. The most common ADRs causing discontinuation within 3 and 12 months were hepatic function abnormal (n = 137/730; 18.8%) and diarrhoea (n = 190/1442; 13.2%), respectively. At 12 months, the decrease in FVC from baseline was smaller in the 'continued' versus the 'discontinued' subgroup (adjusted mean ± standard error change - 104.4 ± 10.9 ml vs. - 311.2 ± 29.2 ml). Stage III/IV IPF and FVC < 70% predicted at baseline were risk factors for early treatment discontinuation.ConclusionAbout 50% of Japanese patients with IPF discontinued nintedanib within the first year of treatment, with worse lung function being associated with an increased risk of early treatment discontinuation.Trial registrationClinicalTrials.gov: NCT02607722; European Union electronic register of Post-Authorisation Studies: EUPAS10891.

Project description:BackgroundEculizumab, a humanized monoclonal antibody targeted to terminal complement protein C5, is approved in Japan for treatment of patients with anti-acetylcholine receptor antibody-positive (AChR+) generalized myasthenia gravis (gMG) whose symptoms are difficult to control with high-dose intravenous immunoglobulin (IVIg) therapy or plasmapheresis.MethodsThis interim analysis of mandatory post-marketing surveillance in Japan assessed the safety and effectiveness of eculizumab at 26 weeks after treatment initiation in patients with AChR+ gMG.ResultsData were available for 40 adult patients in Japan [62.5% (25/40) female; mean age at eculizumab initiation, 51.0 years]. Fifteen patients had a history of thymoma. Six patients were excluded from the effectiveness analysis set due to participation in the open-label extension part of the phase III, randomized, double-blind, placebo-controlled REGAIN study [ClinicalTrials.gov identifier: NCT02301624]. After 26 weeks' follow up, 32 patients (80%) were continuing eculizumab treatment. Adverse drug reactions were reported by seven patients [most frequently headache (n = 3)]. One death was reported during eculizumab treatment (relationship unclear as determined by the treating physician) and there was one death 45 days after the last dose (considered unrelated). No meningococcal infections were reported. Mean (standard deviation) changes from baseline in Myasthenia Gravis-Activities of Daily Living (MG-ADL) and Quantitative Myasthenia Gravis (QMG) scores were -3.7 (2.61) (n = 27) and -5.6 (3.50) (n = 26), respectively, at 12 weeks, and -4.3 (2.72) (n = 26) and -5.6 (4.02) (n = 24), respectively, at 26 weeks. Improvements in MG-ADL and QMG scores were generally similar in patients with/without a history of thymoma. Frequency of IVIg use decreased following eculizumab initiation.ConclusionIn a real-world setting, eculizumab was effective and well tolerated for the treatment of AChR+ gMG in adult Japanese patients whose disease was refractory to IVIg or plasmapheresis. These findings are consistent with the efficacy and safety results from the global phase III REGAIN study of eculizumab.

Project description:IntroductionTeneligliptin is a dipeptidyl peptidase 4 inhibitor that was approved for the treatment of type 2 diabetes mellitus (T2DM) in Japan in 2012. We performed a long-term post-marketing surveillance (RUBY) to obtain real-world evidence regarding the safety and efficacy of teneligliptin in Japan.MethodsThis 3-year follow-up RUBY surveillance registered patients with T2DM who started treatment with teneligliptin between May 2013 and February 2015 in Japan. Collected data included demographics, treatments, adverse drug reactions (ADRs) and laboratory variables. Data were evaluated in all patients and in patients divided according to baseline renal function across categories of estimated glomerular filtration rate (G1-G5) and dialysis. Safety was assessed as the incidence of ADRs and efficacy was assessed in terms of glycaemic control, for up to 3 years.ResultsOf 11,677 patients registered, 10,696 and 10,249 were evaluable for safety and efficacy analyses, respectively. The median duration of exposure was 1096 days. ADRs occurred in 412 patients (3.85%) and were serious in 117 patients (1.09%). The most frequent ADR class was gastrointestinal disorders (0.68%), which included constipation. There were no new ADRs warranting attention beyond those already described in teneligliptin's package insert. ADRs and serious ADRs in renal function subgroups occurred in 3.24-7.14% and 0.65-5.36% in G1-G5, and 4.49% and 1.92% in patients on dialysis, respectively. Reduction in HbA1c was sustained for 3 years after starting teneligliptin (- 0.70% ± 1.36%, p < 0.001 at 3 years). The least-squares mean changes in HbA1c adjusted for baseline were - 0.76% to - 0.66% in G1-G5 at 3 years. Glycated albumin levels decreased in patients on dialysis (- 2.92% ± 4.78% at 3 years).ConclusionThere were no new safety or efficacy concerns about teneligliptin used in long-term, real-world, clinical settings in patients with T2DM with any stages of renal impairment.Trial registrationJapan Pharmaceutical Information Center clinical trials database identifier: Japic CTI-153047.
