Long-term safety and effectiveness of biosimilar insulin glargine in Japanese patients with diabetes mellitus in routine clinical practice: results of a post-marketing safety study

Abstract

Objective: To evaluate the long-term safety and effectiveness of biosimilar insulin glargine (GLY) in real-world clinical practice.

Methods: This prospective, non-interventional, multicenter, observational, post-marketing safety study (PMSS) enrolled Japanese patients with type 1 or 2 diabetes mellitus (T1DM or T2DM) starting GLY therapy, and was required by Japanese Pharmaceutical Affairs Law mandating post-marketing safety surveillance to acquire safety and effectiveness data of biosimilar products. Data collected from the 12-month observation included patient characteristics, adverse events, and blood glucose control.

Results: The study enrolled 141 patients with T1DM and 1104 patients with T2DM. Pre-study insulin was used by 94.1% of patients with T1DM and 75.0% with T2DM. 65.4% of patients with T1DM and 64.3% with T2DM switched from the reference product (GLY-switched), while 25.0% with T2DM were insulin-naive. Adverse events were reported by 5.7% and 8.5% in T1DM and T2DM, respectively. Similar incidences were reported in GLY-switched. Adverse events were reported by 10.7% in insulin-naive T2DM. Baseline mean hypoglycemic events/month were 1.8 and 0.1 in T1DM and T2DM, respectively: the mean change from baseline (CFB) was –1.2 (p?=?.066) and 0.0 (p?=?.915), respectively. Baseline mean HbA1c was 8.4% and 8.7% in T1DM and T2DM, respectively; the mean CFB was –0.5% (p?<?.001) and –0.9% (p?<?.001), respectively, and –1.5% (p?<?.001) in insulin-naive T2DM.

Conclusions: This first long-term Japanese PMSS of GLY demonstrated adverse events, hypoglycemia, and glycemic control consistent with the known GLY profile for T1DM and T2DM patients, in routine clinical practice.

Phase 1 Study of Erlotinib and Metformin in Metastatic Triple-Negative Breast Cancer

BackgroundEpidermal growth factor receptor (EGFR) is frequently overexpressed in metastatic triple-negative breast cancer (mTNBC). One strategy for overcoming resistance to EGFR inhibition is concomitant inhibition of downstream signaling. The antidiabetic drug metformin inhibits both MAPK and PI3K/mTOR pathway signaling. We evaluated the combination of erlotinib and metformin in a phase 1 study of patients with mTNBC.Patients and MethodsPatients with mTNBC who had received at least one prior line of therapy for metastatic disease were eligible. Erlotinib dose was fixed at 150 mg daily. Metformin dose escalation was planned according to a 3 + 3 design. Dose-limiting toxicities (DLT) were assessed during the first 5 weeks of therapy. The primary objective was to determine the maximum tolerated dose of metformin with fixed-dose erlotinib. Secondary endpoints were response rate, stable disease rate, and progression-free survival.ResultsEight patients were enrolled. The median number of prior therapies for metastatic disease was 2.5 (range, 1-6). No DLT events were reported during the DLT assessment period. Most adverse events were grade 1/2. Grade 3 diarrhea despite maximum supportive care required dose reduction of metformin in one patient. Grade 3 rash led to study withdrawal in one patient. No grade 4 adverse events were reported. The best observed response was stable disease in 2 patients (25%). Median progression-free survival was 60 days (range, 36-61 days).ConclusionErlotinib and metformin were well tolerated in a population of pretreated mTNBC patients but did not demonstrate efficacy in this population.

Design,synthesis, and evaluation of novel cinnamic acid-tryptamine hybrid for inhibition of acetylcholinesterase and butyrylcholinesterase

BackgroundAcetylcholine deficiencies in hippocampus and cortex, aggregation of β-amyloid, and β-secretase over activity have been introduced as main reasons in pathogenesis of Alzheimer’s disease.MethodsColorimetric Ellman’s method was used for determination of IC₅₀ value in AChE and BChE inhibitory activity. The kinetic studies, neuroprotective and β-secretase inhibitory activities, evaluation of inhibitory potency on β-amyloid (Aβ) aggregations induced by AChE, and docking study were performed for prediction of the mechanism of action.Result and discussionA new series of cinnamic acids-tryptamine hybrid was designed, synthesized, and evaluated as dual cholinesterase inhibitors. These compounds demonstrated in-vitro inhibitory activities against acetyl cholinesterase (AChE) and butyryl cholinesterase (BChE). Among of these synthesized compounds, (E)-N-(2-(1H-indol-3-yl)ethyl)-3-(3,4-dimethoxyphenyl)acrylamide (5q) demonstrated the most potent AChE inhibitory activity (IC₅₀ = 11.51 μM) and (E)-N-(2-(1H-indol-3-yl)ethyl)-3-(2-chlorophenyl)acrylamide (5b) were the best anti-BChE (IC₅₀ = 1.95 μM) compounds. In addition, the molecular modeling and kinetic studies depicted 5q and 5b were mixed type inhibitor and bound with both the peripheral anionic site (PAS) and catalytic sites (CAS) of AChE and BChE. Moreover, compound 5q showed mild neuroprotective in PC12 cell line and weak β-secretase inhibitory activities. This compound also inhibited aggregation of β-amyloid (Aβ) in self-induced peptide aggregation test at concentration of 10 μM.ConclusionIt is worth noting that both the kinetic study and the molecular modeling of 5q and 5b depicted that these compounds simultaneously interacted with both the catalytic active site and the peripheral anionic site of AChE and BChE. These findings match with those resulted data from the enzyme inhibition assay. Graphical abstractOpen in a separate windowA new series of cinnamic-derived acids-tryptamine hybrid derivatives were designed, synthesized and evaluated as butyrylcholinesterase (BChE) and acetylcholinesterase (AChE) inhibitors and neuroprotective agents. Compound 5b and 5q, as the more potent compounds, interacted with both the peripheral site and the choline binding site having mixed type inhibition. Results suggested that derivatives have a therapeutic potential for the treatment of AD.Electronic supplementary materialThe online version of this article (10.1007/s40199-020-00346-9) contains supplementary material, which is available to authorized users.     

Burden of Cirrhosis and Other Chronic Liver Diseases Caused by Specific Etiologies in China, 1990-2016:Findings from the Global Burden of Disease Study 2016

Objective To estimate the burden of cirrhosis and other chronic liver diseases caused by specific etiologies in China.Methods Data from the Global Burden of Disease Study 2016(GBD 2016) were used. We evaluated the burden by analyzing age-sex-province-specific prevalence, mortality, and disability-adjusted lifeyears(DALYs) of 33 provinces in China.Results From 1990 to 2016, prevalence cases in thousands increased by 73.7% from 6833.3(95% UI:6498.0–7180.6) to 11869.6(95% UI: 11274.6–12504.7). Age-standardized mortality and DALY rates per100,000 decreased by 51.2% and 53.3%, respectively. Male and elderly people(aged ≥ 60 years)preponderance were found for prevalence, mortality, and DALYs. The number of prevalence cases,deaths, and DALYs due to hepatitis C virus(HCV) increased by 86.6%, 8.7%, and 0.9%, respectively. Also,age-standardized prevalence rates decreased in 31 provinces, but increased in Yunnan and Shandong.The Socio-demographic Index(SDI) values were negatively correlated with age-standardized mortality and DALY rates by provinces in 2016; the correlation coefficients were-0.817 and-0.828, respectively.Conclusion Cirrhosis and other chronic liver diseases remain a huge health burden in China, with the increase of population and the aging of population. Hepatitis B virus(HBV) remains the leading cause of the health burden in China.
