Tirzepatide Once Weekly for the Treatment of Obesity.

BACKGROUND: Obesity is a chronic disease that results in substantial global morbidity and mortality. The efficacy and safety of tirzepatide, a novel glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptor agonist, in people with obesity are not known. METHODS: In this phase 3 double-blind, randomized, controlled trial, we assigned 2539 adults with a body-mass index (BMI; the weight in kilograms divided by the square of the height in meters) of 30 or more, or 27 or more and at least one weight-related complication, excluding diabetes, in a 1:1:1:1 ratio to receive once-weekly, subcutaneous tirzepatide (5 mg, 10 mg, or 15 mg) or placebo for 72 weeks, including a 20-week dose-escalation period. Coprimary end points were the percentage change in weight from baseline and a weight reduction of 5% or more. The treatment-regimen estimand assessed effects regardless of treatment discontinuation in the intention-to-treat population. RESULTS: At baseline, the mean body weight was 104.8 kg, the mean BMI was 38.0, and 94.5% of participants had a BMI of 30 or higher. The mean percentage change in weight at week 72 was -15.0% (95% confidence interval [CI], -15.9 to -14.2) with 5-mg weekly doses of tirzepatide, -19.5% (95% CI, -20.4 to -18.5) with 10-mg doses, and -20.9% (95% CI, -21.8 to -19.9) with 15-mg doses and -3.1% (95% CI, -4.3 to -1.9) with placebo (P<0.001 for all comparisons with placebo). The percentage of participants who had weight reduction of 5% or more was 85% (95% CI, 82 to 89), 89% (95% CI, 86 to 92), and 91% (95% CI, 88 to 94) with 5 mg, 10 mg, and 15 mg of tirzepatide, respectively, and 35% (95% CI, 30 to 39) with placebo; 50% (95% CI, 46 to 54) and 57% (95% CI, 53 to 61) of participants in the 10-mg and 15-mg groups had a reduction in body weight of 20% or more, as compared with 3% (95% CI, 1 to 5) in the placebo group (P<0.001 for all comparisons with placebo). Improvements in all prespecified cardiometabolic measures were observed with tirzepatide. The most common adverse events with tirzepatide were gastrointestinal, and most were mild to moderate in severity, occurring primarily during dose escalation. Adverse events caused treatment discontinuation in 4.3%, 7.1%, 6.2%, and 2.6% of participants receiving 5-mg, 10-mg, and 15-mg tirzepatide doses and placebo, respectively. CONCLUSIONS: In this 72-week trial in participants with obesity, 5 mg, 10 mg, or 15 mg of tirzepatide once weekly provided substantial and sustained reductions in body weight.

Zibotentan in combination with dapagliflozin compared with dapagliflozin in patients with chronic kidney disease (ZENITH-CKD): a multicentre, randomised, active-controlled, phase 2b, clinical trial.

BACKGROUND: In patients with chronic kidney disease, SGLT2 inhibitors and endothelin A receptor antagonists (ERAs) can reduce albuminuria and glomerular filtration rate (GFR) decline. We assessed the albuminuria-lowering efficacy and safety of the ERA zibotentan combined with the SGLT2 inhibitor dapagliflozin. METHODS: ZENITH-CKD was a multicentre, randomised, double-blind, active-controlled clinical trial, done in 170 clinical practice sites in 18 countries. Adults (≥18 to ≤90 years) with an estimated GFR (eGFR) of 20 mL/min per 1·73 m2 or greater and a urinary albumin-to-creatinine ratio (UACR) of 150-5000 mg/g were randomly assigned (2:1:2) to 12 weeks of daily treatment with zibotentan 1·5 mg plus dapagliflozin 10 mg, zibotentan 0·25 mg plus dapagliflozin 10 mg, or dapagliflozin 10 mg plus placebo, as adjunct to angiotensin-converting enzyme inhibitors or angiotensin receptor blockers if tolerated. The primary endpoint was a change from baseline in log-transformed UACR (zibotentan 1·5 mg plus dapagliflozin vs dapagliflozin plus placebo) at week 12. Fluid retention was an event of special interest, defined as an increase in bodyweight of at least 3% (at least 2·5% must have been from total body water) from baseline or an increase of at least 100% in B-type natriuretic peptide (BNP) and either a BNP concentration greater than 200 pg/mL if without atrial fibrillation or BNP greater than 400 pg/mL if with atrial fibrillation. This trial is registered with ClinicalTrials.gov, NCT04724837, and is completed. FINDINGS: Between April 28, 2021, and Jan 17, 2023, we assessed 1492 participants for eligibility. For the main analysis, we randomly assigned 449 (30%) participants, 447 (99%) of whom (mean age 62·8 years [SD 12·1], 138 [31%] female, 309 [69%] male, 305 [68%] White, mean eGFR 46·7 mL/min per 1·73 m2 [SD 22·4], and median UACR 565·5 mg/g [IQR 243·0-1212·6]) received treatment with zibotentan 1·5 mg plus dapagliflozin (n=179 [40%]), zibotentan 0·25 mg plus dapagliflozin (n=91 [20%]), or dapagliflozin plus placebo (n=177 [40%]). Zibotentan 1·5 mg plus dapagliflozin and zibotentan 0·25 mg plus dapagliflozin reduced UACR versus dapagliflozin plus placebo throughout the treatment period of the study. At week 12, the difference in UACR versus dapagliflozin plus placebo was -33·7% (90% CI -42·5 to -23·5; p<0·0001) for zibotentan 1·5 mg plus dapagliflozin and -27·0% (90% CI -38·4 to -13·6; p=0·0022) for zibotentan 0·25 mg plus dapagliflozin. Fluid-retention events were observed in 33 (18%) of 179 participants in the zibotentan 1·5 mg plus dapagliflozin group, eight (9%) of 91 in the zibotentan 0·25 mg plus dapagliflozin group, and 14 (8%) of 177 in the dapagliflozin plus placebo group. INTERPRETATION: Zibotentan combined with dapagliflozin reduced albuminuria with an acceptable tolerability and safety profile and is an option to reduce chronic kidney disease progression in patients already receiving currently recommended therapy.

Safety and efficacy analyses across age and body mass index subgroups in East Asian participants with type 2 diabetes in the phase 3 tirzepatide studies (SURPASS programme).

AIM: To assess the safety and efficacy of tirzepatide in people of East Asian descent based on age and body mass index (BMI). MATERIALS AND METHODS: Data of participants enrolled in East Asian countries in the SURPASS-1, -3, -4, -5, J-mono and J-combo phase 3 clinical trials were included. Participants with type 2 diabetes with a baseline HbA1c of 7.0% up to 11.0% and a BMI of 23 kg/m2 or greater or 25 kg/m2 or greater were included. Participants treated with tirzepatide 5, 10 or 15 mg were evaluated to assess the safety and efficacy of tirzepatide in people of East Asian descent (94% from Japan) based on age (< 65 and ≥ 65 years) and BMI (< 25 and ≥ 25 kg/m2 ). Key safety and efficacy outcomes were assessed. RESULTS: At baseline, 73% of East Asian participants had a BMI of 25 kg/m2 or greater and 74% were younger than 65 years. At week 52, tirzepatide induced a similar dose-dependent reduction in HbA1c, waist circumference and BMI across subgroups. Across all BMI and age subgroups, mean absolute HbA1c reductions across the three doses ranged from 2.3% to 3.0%, and mean waist circumference reductions ranged from 4.3 to 9.8 cm. Improvements in absolute insulin sensitivity, assessed by homeostatic model assessment for insulin resistance, were greater in those with a baseline BMI of ≥ 25 kg/m2 . Improvements in lipid profiles were similar across subgroups. While the safety profile of tirzepatide was broadly similar across BMI and age subgroups, drug discontinuation because of adverse events was higher in participants with a baseline age of ≥ 65 years. CONCLUSIONS: This post hoc analysis showed that once-weekly tirzepatide had a similar safety and efficacy profile across BMI and age subgroups in East Asian participants.

Safety and Effectiveness of Alirocumab, a Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) Inhibitor, in Patients With Familial or Non-Familial Hypercholesterolemia　- A Post-Marketing Survey (J-POSSIBLE).

BACKGROUND: This study evaluated the safety and effectiveness of alirocumab in Japanese patients with familial hypercholesterolemia (FH) or non-FH in a real-world clinical setting.Methods and Results: This post-marketing surveillance study had a 2-year standard observation period. The study included Japanese patients with hypercholesterolemia who were treatment naïve to alirocumab, had a high risk of developing cardiovascular events, and had an insufficient response to, or were unsuitable for, treatment with 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors. Alirocumab was administered at a dose of 75 or 150 mg via subcutaneous injection every 2 or 4 weeks. Overall, 1,177 and 1,038 patients were included in the safety and effectiveness analysis populations, respectively. The incidence of adverse drug reactions (ADRs) was 3.4% (40/1,177). The time to ADR occurrence was within 4 weeks in half the patients experiencing ADRs (n=20). There were no meaningful differences in the ADRs experienced in the FH and non-FH groups. The mean (±SE) percentage changes in low-density lipoprotein cholesterol from baseline to last observation carried forward were -46.9±2.1% and -42.7±2.0% in the non-FH and FH groups, respectively. Total cholesterol, triglycerides, apolipoprotein B/E, and lipoprotein(a) concentrations were decreased at Week 4 and maintained until Week 104 in the overall population. CONCLUSIONS: Alirocumab was well tolerated and showed effectiveness in Japanese patients with hypercholesterolemia in a real-world clinical setting.

Sex Differences in Long-Term Outcomes in Patients With Chronic Coronary Syndrome After Percutaneous Coronary Intervention　- Insights From a Japanese Real-World Database Using a Storage System.

BACKGROUND: Several studies have reported some sex differences in patients with coronary artery diseases. However, the results regarding long-term outcomes in patients with chronic coronary syndrome (CCS) are inconsistent. Therefore, the present study investigated sex differences in long-term outcomes in patients with CCS after percutaneous coronary intervention (PCI).Methods and Results: This was a retrospective, multicenter cohort study. We enrolled patients with CCS who underwent PCI between April 2013 and March 2019 using the Clinical Deep Data Accumulation System (CLIDAS) database. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, or hospitalization for heart failure. In all, 5,555 patients with CCS after PCI were included in the analysis (4,354 (78.4%) men, 1,201 (21.6%) women). The median follow-up duration was 917 days (interquartile range 312-1,508 days). The incidence of MACE was not significantly different between the 2 groups (hazard ratio [HR] 1.20; 95% confidential interval [CI] 0.97-1.47; log-rank P=0.087). After performing multivariable Cox regression analyses on 4 different models, there were still no differences in the incidence of MACE between women and men. CONCLUSIONS: There were no significant sex differences in MACE in patients with CCS who underwent PCI and underwent multidisciplinary treatments.

Relationships Among Heart Rate, ß-Blocker Dosage, and Prognosis in Patients With Coronary Artery Disease in a Real-World Database Using a Multimodal Data Acquisition System.

BACKGROUND: The optimal heart rate (HR) and optimal dose of ß-blockers (BBs) in patients with coronary artery disease (CAD) have been unclear. We sought to clarify the relationships among HR, BB dose, and prognosis in patients with CAD using a multimodal data acquisition system.Methods and Results: We evaluated the data for 8,744 CAD patients who underwent cardiac catheterization from 6 university hospitals and the National Cerebral and Cardiovascular Center and who were registered using the Clinical Deep Data Accumulation System. Patients were divided into quartile groups based on their HR at discharge: Q1 (HR <60 beats/min), Q2 (HR 60-66 beats/min), Q3 (HR 67-74 beats/min), and Q4 (HR ≥75 beats/min). Among patients with acute coronary syndrome (ACS) and patients with chronic coronary syndrome (CCS), those in Q4 (HR ≥75 beats/min) had a significantly greater incidence of major adverse cardiac and cerebral events (MACCE) compared with those in Q1 (ACS patients: hazard ratio 1.65, P=0.001; CCS patients: hazard ratio 1.45, P=0.019). Regarding the use of BBs (n=4,964), low-dose administration was significantly associated with MACCE in the ACS group (hazard ratio 1.41, P=0.012), but not in patients with CCS after adjustment for covariates. CONCLUSIONS: HR ≥75 beats/min was associated with worse outcomes in patients with CCS or ACS.

Effect of canagliflozin on N-terminal pro-brain natriuretic peptide in patients with type 2 diabetes and chronic heart failure according to baseline use of glucose-lowering agents.

BACKGROUND: Sodium-glucose cotransporter 2 (SGLT2) inhibitors reduce the risk of a deterioration in heart failure (HF) and mortality in patients with a broad range of cardiovascular risks. Recent guidelines recommend considering the use of SGLT2 inhibitors in patients with type 2 diabetes (T2D) and HF, irrespective of their glycemic control status and background use of other glucose-lowering agents including metformin. However, only a small number of studies have investigated whether the effects of SGLT2 inhibitor in these patients differ by the concomitant use of other glucose-lowering agents. METHODS: This was a post-hoc analysis of the CANDLE trial (UMIN000017669), an investigator-initiated, multicenter, open-label, randomized, controlled trial. The primary aim of the analysis was to assess the effect of 24 weeks of treatment with canagliflozin, relative to glimepiride, on N-terminal pro-brain natriuretic peptide (NT-proBNP) concentration in patients with T2D and clinically stable chronic HF. In the present analysis, the effect of canagliflozin on NT-proBNP concentration was assessed in the patients according to their baseline use of other glucose-lowering agents. RESULTS: Almost all patients in the CANDLE trial presented as clinically stable (New York Heart Association class I to II), with about 70% of participants having HF with a preserved ejection fraction phenotype (defined as a left ventricular ejection fraction ≥ 50%) at baseline. Of the 233 patients randomized to either canagliflozin (100 mg daily) or glimepiride (starting dose 0.5 mg daily), 85 (36.5%) had not been taking any glucose-lowering agents at baseline (naïve). Of the 148 patients who had been taking at least one glucose-lowering agent at baseline (non-naïve), 44 (29.7%) and 127 (85.8%) had received metformin or a dipeptidyl dipeptidase-4 (DPP-4) inhibitor, respectively. The group ratio (canagliflozin vs. glimepiride) of proportional changes in the geometric means of NT-proBNP concentration was 0.95 (95% confidence interval [CI] 0.76 to 1.18, p = 0.618) for the naïve subgroup, 0.92 (95% CI 0.79 to1.07, p = 0.288) for the non-naïve subgroup, 0.90 (95% CI 0.68 to 1.20, p = 0.473) for the metformin-user subgroup, and 0.91 (95% CI 0.77 to 1.08, p = 0.271) for the DPP-4 inhibitor-user subgroup. No heterogeneity in the effect of canagliflozin, relative to glimepiride, on NT-proBNP concentration was observed in the non-naïve subgroups compared to that in the naïve subgroup. CONCLUSION: The impact of canagliflozin treatment on NT-proBNP concentration appears to be independent of the background use of diabetes therapy in the patient population examined.

Detection of Profound Myocardial Damage by Cardiac MRI in a Patient with Severe Cardiotoxicity Induced by Anti-HER2 Therapy.

Anti-HER2 therapy has greatly improved the long-term prognosis of patients with HER2-positive breast cancer. Meanwhile, by interfering with the protective effects of neuregulin-1/HER2 signaling on stressed cardiomyocytes, anti-HER2 therapy occasionally induces reversible cancer therapeutics-related cardiac dysfunction (CTRCD). Cardiac magnetic resonance (CMR) parametric mapping or myocardial feature-tracking, in combination with late gadolinium enhancement (LGE) imaging, has the potential to detect changes in the myocardium in anti-HER2 therapy-related cardiac dysfunction. Here we report a breast cancer patient who experienced life-threatening CTRCD after treatment with trastuzumab plus pertuzumab. This case showed multiple transmural LGE-positive myocardial lesions in CMR imaging and high native T1 and T2 values in CMR parametric mapping, which was apparently more extensive than those observed in most patients with anti-HER2 therapy-related cardiac dysfunction. Consistent with profound myocardial damage indicated by CMR, her cardiac function was not fully restored despite intensive care and cardioprotective drug therapy. These findings suggest the potential usefulness of LGE imaging and parametric mapping by CMR for the assessment of myocardial injury to determine the clinical severity of anti-HER2 therapy-related cardiac dysfunction.

Histone methylation and demethylation are implicated in the transient and sustained activation of the interleukin-1ß gene in murine macrophages.

Macrophages play a crucial role in the development of atherosclerosis. To explore the mechanism by which macrophages attain a proinflammatory phenotype for a sustained period, we stimulated macrophages with lipopolysaccharide (LPS) and interferon-γ (IFN-γ) and measured the interleukin-1ß (IL-1ß) expression. The IL-1ß expression increased transiently, and its expression lasted for, at least, 1 week after the cessation of LPS and IFN-γ stimulation. At the promoter region of the IL-1ß gene, the demethylation of histone H3 lysine 27 (H3K27) was significantly induced for 1 week after transient stimulation with LPS and IFN-γ. The expression of H3K27 demethylases ubiquitously transcribed tetratricopeptide repeat, X chromosome (UTX) and jumonji domain-containing 3 (JMJD3) increased significantly for 1 week after transient stimulation with LPS and IFN-γ. When the UTX expression was inhibited by using small interfering RNA (siRNA) for UTX, the IL-1ß expression was significantly suppressed in both transient and sustained phases, whereas siRNA for JMJD3 significantly inhibited only the sustained phase of the IL-1ß expression. These results suggested that H3K27 demethylation was implicated in the transient and sustained increase in the IL-1ß expression after LPS and IFN-γ stimulation.

Efficacy of Fractional Flow Reserve-Guided Percutaneous Cornary Intervention for Patients with Angina Pectoris.

Evaluation of hemodynamic parameters, such as fractional flow reserve (FFR), is recommended before percutaneous coronary intervention (PCI) for patients with angina pectoris (AP). However, the advantage of FFR-guided PCI has not been fully established. This study was performed to confirm whether FFR-guided PCI improves the prognosis compared with other treatments. Multiple databases were searched for studies published from 2000 to 2018, and a network meta-analysis (NMA) was performed to compare outcomes of FFR-guided PCI, non-FFR-guided PCI, coronary artery bypass grafting (CABG), and medical treatment (MT) for AP based on estimated odds ratios (ORs). The study included 18,093 patients from 15 randomized controlled trials (RCTs). No evidence of inconsistency was observed among the studies. The NMA showed that the all-cause mortality of FFR-guided PCI was not significantly different from that of the other treatment groups (CABG: OR, 1.1; 95% confidence interval [CI], 0.67-1.7; non-FFR-guided PCI: OR, 0.85; 95% CI, 0.53-1.4; and MT: OR, 0.83; 95% CI, 0.52-1.3). The NMA for the composite of all-cause mortality and myocardial infarction, which included 15,454 patients from 12 RCTs, showed that FFR-guided PCI significantly reduced the composite outcome compared with non-FFR-guided PCI and MT (non-FFR-guided PCI: OR, 0.66; 95% CI, 0.46-0.95 and MT: OR, 0.66; 95% CI, 0.46-0.95). Although FFR-guided PCI for AP did not show significant prognostic improvement compared with non-FFR-guided PCI, CABG, and MT, FFR-guided PCI may significantly reduce the composite of all-cause mortality and myocardial infarction compared with non-FFR-guided PCI and MT.

Novel Balloon Pulmonary Angioplasty Technique for Chronic Thromboembolic Pulmonary Hypertension.

This study aimed to clarify the usefulness of the Ikari-curve left (IL) guiding catheter for balloon pulmonary angioplasty (BPA).The current BPA strategy for chronic thromboembolic pulmonary hypertension is dilation of as many branches as possible to normalize hemodynamics and oxygenation. The shape of the guiding catheter is a major factor in achieving this. However, conventional guiding catheters are difficult to introduce into particular branches. The IL guiding catheter may be suitable; however, its utility remains unclear.We retrospectively analyzed 202 consecutive BPA sessions of 40 patients from November 2016 to October 2019 and divided these sessions into two groups: the IL group where the IL guiding catheter was used and the non-IL group where other catheters were utilized. The occurrence of lung injury was determined by the presence of bloody sputum. We compared the rates of successful introduction into target vessels and assessed for the occurrence of lung injury.The average age of enrolled patients was 60.3 ± 14.4 years, with females comprising 65%. There were 99 sessions in the IL group. The median treated branches per session differed between the 2 groups (IL group: 15 versus non-IL group: 10, P < 0.05). The occurrence of lung injury was lower in the IL group (4.0% versus 11.7%, P = 0.07). The IL group had more successful vessel insertions than the non-IL group (78.8% versus 42.7%, P < 0.01).The IL guiding catheter may be introduced into branches that cannot be accessed by conventional guiding catheters.

Diagnosing Heart Failure from Chest X-Ray Images Using Deep Learning.

The development of deep learning technology has enabled machines to achieve high-level accuracy in interpreting medical images. While many previous studies have examined the detection of pulmonary nodules in chest X-rays using deep learning, the application of this technology to heart failure remains rare. In this paper, we investigated the performance of a deep learning algorithm in terms of diagnosing heart failure using images obtained from chest X-rays. We used 952 chest X-ray images from a labeled database published by the National Institutes of Health. Two cardiologists verified and relabeled a total of 260 "normal" and 378 "heart failure" images, with the remainder being discarded because they had been incorrectly labeled. Data augmentation and transfer learning were used to obtain an accuracy of 82% in diagnosing heart failure using the chest X-ray images. Furthermore, heatmap imaging allowed us to visualize decisions made by the machine. Deep learning can thus help support the diagnosis of heart failure using chest X-ray images.

Cost-Effectiveness of Percutaneous Coronary Intervention Compared With Medical Therapy for Ischemic Heart Disease in Japan.

BACKGROUND: The cost-effectiveness of percutaneous coronary intervention (PCI) for ischemic heart disease is undetermined in Japan. The aim of this study was to analyze the cost-effectiveness of PCI compared with medical therapy for ST-elevation myocardial infarction (STEMI) and angina pectoris (AP) in Japan.Methods and Results:We used Markov models for STEMI and AP to assess the costs and benefits associated with PCI or medical therapy from a health system perspective. We estimated the incremental cost-effectiveness ratio (ICER), expressed as quality-adjusted life-years (QALY), and ICER <¥5 m per QALY gained was judged to be cost-effective. The impact of PCI on cardiovascular events was based on previous publications. In STEMI patients, the ICER of PCI over medical treatment was ¥0.97 m per QALY gained. The cost-effectiveness probability of PCI was 99.9%. In AP patients, the ICER of fractional flow reserve (FFR)-guided PCI over medical treatment was ¥4.63 m per QALY gained. The cost-effectiveness probability of PCI was 50.4%. The ICER of FFR-guided PCI for asymptomatic patients was ¥23 m per QALY gained. CONCLUSIONS: In STEMI patients, PCI was cost-effective compared with medical therapy. In AP patients, FFR-guided PCI for symptomatic patients could be cost-effective compared with medical therapy. FFR-guided PCI for asymptomatic patients with myocardial ischemia was not cost-effective.

Long-Term Treatment With Evolocumab Among Japanese Patients　- Final Report of the OSLER Open-Label Extension Studies.

BACKGROUND: Treatment with evolocumab reduces mean low-density lipoprotein cholesterol (LDL-C) up to 75% and cardiovascular events by 16% in the first year and 25% thereafter. Methods and Results: Japanese patients with hypercholesterolemia enrolled in the parent YUKAWA-1-2 studies could enroll, once eligible, in the OSLER studies (n=556). OSLER re-randomized patients 2:1 to evolocumab plus standard of care (SOC; evolocumab+SOC) or SOC alone for 1 year; after year 1, patients could enter the all-evolocumab+SOC open-label extension of OSLER. Patients received evolocumab+SOC from the 2nd year through up to 5 years. Long-term efficacy and safety, including antidrug antibodies, were evaluated. Of 556 patients, 532 continued to the all-evolocumab+SOC extension: mean (standard deviation [SD]) age 61 (10) years, 39% female. A total of 91% of 532 patients completed the studies. Mean (SD) LDL-C change from parent-study baseline with evolocumab from a mean (SD) baseline of 142.3 (21.3) and 105.0 (31.1) mg/dL in OSLER-1 and OSLER-2, respectively, was maintained through the end of the study: -58.0% (19.1%) at year 5 in OSLER-1, -62.7% (25.6%) at year 3 in OSLER-2. The overall safety profile of the evolocumab+SOC periods was similar to that of the year-1 controlled period. Antidrug antibodies were detected transiently in 3 patients. No neutralizing antibodies were detected. CONCLUSIONS: Japanese patients who continued evolocumab+SOC for up to 5 years experienced sustained high LDL-C level reduction. Long-term evolocumab+SOC exposure showed no new safety signals.

Overview of the 83rd Annual Scientific Meeting of the Japanese Circulation Society　- Renaissance of Cardiology for the Creation of Future Medicine.

The 83rdAnnual Scientific Meeting of the Japanese Circulation Society was held in Yokohama, Japan, on March 29-31, 2019, just as the cherry blossoms came into full bloom. Because the environment around cardiovascular healthcare is rapidly changing, it becomes highly important to make a breakthrough at the dawn of a new era. The main theme of this meeting was "Renaissance of Cardiology for the Creation of Future Medicine". The meeting benefited from the participation of 18,825 people, and there were in-depth and extensive discussions at every session, focusing on topics covering clinical and basic research, medical care provision system, human resource development, and public awareness in cardiovascular medicine. The meeting was completed with great success, and we greatly appreciate the tremendous cooperation and support from all affiliates.

Clinical Efficacy of Telemedicine Compared to Face-to-Face Clinic Visits for Smoking Cessation: Multicenter Open-Label Randomized Controlled Noninferiority Trial.

BACKGROUND: Tobacco is a major public health concern. A 12-week standard smoking cessation program is available in Japan; however, it requires face-to-face clinic visits, which has been one of the key obstacles to completing the program, leading to a low smoking cessation success rate. Telemedicine using internet-based video counseling instead of regular clinic visits could address this obstacle. OBJECTIVE: This study aimed to evaluate the efficacy and feasibility of an internet-based remote smoking cessation support program compared with the standard face-to-face clinical visit program among patients with nicotine dependence. METHODS: This study was a randomized, controlled, open-label, multicenter, noninferiority trial. We recruited nicotine-dependent adults from March to June 2018. Participants randomized to the telemedicine arm received internet-based video counseling, whereas control participants received standard face-to-face clinic visits at each time point in the smoking cessation program. Both arms received a CureApp Smoking Cessation smartphone app with a mobile exhaled carbon monoxide checker. The primary outcome was a continuous abstinence rate (CAR) from weeks 9 to 12. Full analysis set was used for data analysis. RESULTS: We randomized 115 participants with nicotine dependence: 58 were allocated to the telemedicine (internet-based video counseling) arm and 57, to the control (standard face-to-face clinical visit) arm. We analyzed all 115 participants for the primary outcome. Both telemedicine and control groups had similar CARs from weeks 9 to 12 (81.0% vs 78.9%; absolute difference, 2.1%; 95% CI -12.8 to 17.0), and the lower limit of the difference between groups (-12.8%) was greater than the prespecified limit (-15%). CONCLUSIONS: The application of telemedicine using internet-based video counseling as a smoking cessation program had a similar CAR from weeks 9 to 12 as that of the standard face-to-face clinical visit program. The efficacy of the telemedicine-based smoking cessation program was not inferior to that of the standard visit-based smoking cessation program.

Short-Term and Long-Term Efficacy of Drug-Coated Balloon for In-Stent Restenosis in Hemodialysis Patients with Coronary Artery Disease.

The efficacy of drug-coated balloons (DCB) for in-stent restenosis (ISR) in hemodialysis (HD) patients remains unclear.We retrospectively evaluated 153 consecutive patients who underwent DCB for ISR with follow-ups for up to 3 years after the procedure between February 2014 and June 2017. Patients were divided into an HD group (n = 39) and a non-HD group (n = 114). The primary endpoint was target lesion revascularization (TLR). The secondary endpoints were all revascularizations and major adverse cardiac events (MACE) defined as cardiac death, myocardial infarction and cerebral infarction. Kaplan-Meier curves of survival free from TLR were compared between the two groups. We also performed propensity score matching and then compared the two matched groups (n = 27 in each group). The acute procedure success rate was similar for the two groups (100% versus 99.1%, P = 0.56). The incidence of TLR was higher in the HD group than in the non-HD group (41.0% versus 9.6%, P < 0.0001). The rate of revascularizations and MACE combined was significantly higher in the HD group than in the non-HD group (64.1% versus 17.5%, P < 0.0001). Kaplan-Meier analyses showed that survival free from TLR was significantly lower in the HD group than in the non-HD group both before and after propensity score matching (P < 0.0001 and P = 0.005, respectively; log-rank test).Contrary to the similar acute procedure success, recurrent ISR and MACE occurred more frequently in HD patients than in non-HD patients after DCB, which indicates poorer long-term efficacy of DCB in HD patients.

Architecture of the Japan Ischemic Heart Disease Multimodal Prospective Data Acquisition for Precision Treatment (J-IMPACT) System.

The utilization of electronic medical records and multimodal medical data is an ideal approach to build a real-time and precision registry type study with a smaller effort and cost, which may fill a gap between evidence-based medicine and the real-world clinical practice. The Japan Ischemic heart disease Multimodal Prospective data Acquisition for preCision Treatment (J-IMPACT) project aimed to build an clinical data registry system that electronically collects not only medical records, but also multimodal data, including coronary angiography and percutaneous coronary intervention (PCI) report, in standardized data formats for clinical studies.The J-IMPACT system comprises the standardized structured medical information exchange (SS-MIX), coronary angiography and intervention reporting system (CAIRS), and multi-purpose clinical data repository system (MCDRS) interconnected within the institutional network. In order to prove the concept, we acquired multimodal medical data of 6 consecutive cases that underwent PCI through the J-IMPACT system in a single center. Data items regarding patient background, laboratory data, prescriptions, and PCI/cardiac catheterization report were correctly acquired through the J-IMPACT system, and the accuracy of the multimodal data of the 4 categories was 100% in all 6 cases.The application of J-IMPACT system to clinical studies not only fills the gaps between randomized clinical trials and real-world medicine, but may also provide real-time big data that reinforces precision treatment for each patient.

Safety and efficacy of once-weekly semaglutide vs additional oral antidiabetic drugs in Japanese people with inadequately controlled type 2 diabetes: A randomized trial.

AIM: To evaluate the safety and efficacy of once-weekly subcutaneous semaglutide as monotherapy or combined with an oral antidiabetic drug (OAD) vs an additional OAD added to background therapy in Japanese people with type 2 diabetes (T2D) inadequately controlled on diet/exercise or OAD monotherapy. METHODS: In this phase III, open-label trial, adults with T2D were randomized 2:2:1 to semaglutide 0.5 mg or 1.0 mg, or one additional OAD (a dipeptidyl peptidase-4 inhibitor, biguanide, sulphonylurea, glinide, α-glucosidase inhibitor or thiazolidinedione) with a different mode of action from that of background therapy. The primary endpoint was number of adverse events (AEs) after 56 weeks. RESULTS: Baseline characteristics were balanced between treatment arms (601 randomized). More AEs were reported in the semaglutide 0.5 mg (86.2%) and 1.0 mg (88.0%) groups than in the additional OAD group (71.7%). These were typically mild/moderate. Gastrointestinal AEs were most frequent with semaglutide, which diminished over time. The mean glycated haemoglobin (HbA1c) concentration (baseline 8.1%) was significantly reduced with semaglutide 0.5 mg and 1.0 mg vs additional OAD (1.7% and 2.0% vs 0.7%, respectively; estimated treatment difference [ETD] vs additional OAD -1.08% and -1.37%, both P < .0001). Body weight (baseline 71.5 kg) was reduced by 1.4 kg and 3.2 kg with semaglutide 0.5 mg and 1.0 mg, vs a 0.4-kg increase with additional OAD (ETD -1.84 kg and -3.59 kg; both P < .0001). For semaglutide-treated participants, >80% achieved an HbA1c concentration <7.0% (Japanese Diabetes Society target). CONCLUSIONS: Semaglutide was well tolerated, with no new safety issues identified. Semaglutide treatment significantly reduced HbA1c and body weight vs additional OAD treatment in Japanese people with T2D.
