    未经证实:基质靶向治疗对肿瘤免疫抑制的影响在很大程度上尚未被研究。RNA寡核苷酸,STNM01已显示抑制负责肿瘤蛋白聚糖合成和基质重塑的碳水化合物磺基转移酶15(CHST15)。这项I/IIa期研究旨在评估STNM01在不可切除的胰腺导管腺癌(PDAC)患者中的安全性和有效性。
    未经批准:这是一个开放标签,STNM01作为吉西他滨联合nab-紫杉醇难治性PDAC二线治疗的剂量递增研究.一个周期包括三次2周内窥镜超声引导的局部注射STNM01,剂量为250、1,000、2,500或10,000nM,与S-1组合(每天两次80-120mg,每3周14天)。主要结果是剂量-剂量毒性(DLT)的发生率。次要结局包括总生存期(OS),肿瘤反应,肿瘤微环境的变化对免疫组织病理学的影响,和安全性(jRCT2031190055)。
    未经批准:共纳入22例患者,最多重复3个循环;未观察到DLT。中位OS为7.8个月。疾病控制率为77.3%;1例患者显示胰腺和肿瘤引流淋巴结可见病变完全消失。较高的肿瘤CHST15表达与基线时较差的CD3+和CD8+T细胞浸润相关。STNM01导致CHST15的显着减少,并在第1周期结束时与S-1组合的肿瘤浸润性CD3和CD8T细胞增加。CD3+T细胞中更高的倍数增加与更长的OS相关。有8个3级不良事件。
    UNASSIGNED:局部注射STNM01作为联合二线治疗的不可切除PDAC患者的耐受性良好。它通过增强肿瘤微环境中的T细胞浸润来延长存活。
    UNASSIGNED:本研究得到了日本医学研究与发展机构(AMED)的支持。
    UNASSIGNED: The impact of stroma-targeting therapy on tumor immune suppression is largely unexplored. An RNA oligonucleotide, STNM01, has been shown to repress carbohydrate sulfotransferase 15 (CHST15) responsible for tumor proteoglycan synthesis and matrix remodeling. This phase I/IIa study aimed to evaluate the safety and efficacy of STNM01 in patients with unresectable pancreatic ductal adenocarcinoma (PDAC).
    UNASSIGNED: This was an open-label, dose-escalation study of STNM01 as second-line therapy in gemcitabine plus nab-paclitaxel-refractory PDAC. A cycle comprised three 2-weekly endoscopic ultrasound-guided locoregional injections of STNM01 at doses of 250, 1,000, 2,500, or 10,000 nM in combination with S-1 (80-120 mg twice a day for 14 days every 3 weeks). The primary outcome was the incidence of dose-liming toxicity (DLT). The secondary outcomes included overall survival (OS), tumor response, changes in tumor microenvironment on immunohistopathology, and safety (jRCT2031190055).
    UNASSIGNED: A total of 22 patients were enrolled, and 3 cycles were repeated at maximum; no DLT was observed. The median OS was 7.8 months. The disease control rate was 77.3%; 1 patient showed complete disappearance of visible lesions in the pancreas and tumor-draining lymph nodes. Higher tumoral CHST15 expression was associated with poor CD3+ and CD8+ T cell infiltration at baseline. STNM01 led to a significant reduction in CHST15, and increased tumor-infiltrating CD3+ and CD8+ T cells in combination with S-1 at the end of cycle 1. Higher fold increase in CD3+ T cells correlated with longer OS. There were 8 grade 3 adverse events.
    UNASSIGNED: Locoregional injection of STNM01 was well tolerated in patients with unresectable PDAC as combined second-line therapy. It prolonged survival by enhancing T cell infiltration in tumor microenvironment.
    UNASSIGNED: The present study was supported by the Japan Agency for Medical Research and Development (AMED).

    UNASSIGNED:干细胞研究(SCR)和再生医学(RM)的突破引起了全球公众的广泛关注。同时,科学界和科学政策试图建立对SCR和RM的适当治理。在这种情况下,科学界与公众之间的有效沟通被视为关键因素。然而,公众态度和利益的多样性没有得到充分审查,尤其是各国之间的差异。
    UNASSIGNED:我们对公众对SCR和RM的态度进行了国际比较。我们在六个国家的人群中分发了一份互联网问卷:日本,韩国,美国,英国,德国,和法国。我们从每个国家收集了100个有效的回复,共获得600份回复。
    未经评估:我们的主要发现是RM利益的多样性,可以表达为用户实用主义,RM的治理和处理,风险,和利益,和科学利益。六个国家的利益优先次序各不相同,这些变化可能会受到政治因素的影响,社会,文化,以及每个国家SCR和RM的媒体背景。
    UNASISIGNED:其含义可以有助于更深入地了解公众态度的多样性,并在全球范围内适当审查SCR和RM的广泛道德和社会关切。
    UNASSIGNED: Breakthroughs in stem cell research (SCR) and regenerative medicine (RM) have attracted significant public attention worldwide. Simultaneously, scientific communities and science policies have tried to establish appropriate governance of SCR and RM. In this context, effective communication between scientific communities and the public is regarded as a key factor. However, the diversity of public attitudes and interests has not been sufficiently examined, especially the differences across countries.
    UNASSIGNED: We conducted an international comparison of public attitudes toward SCR and RM. We circulated an internet questionnaire among people in six countries: Japan, South Korea, the United States, the UK, Germany, and France. We collected 100 valid responses from each country, and a total of 600 responses were obtained.
    UNASSIGNED: Our key findings are the diversity of interests in RM, which can be expressed as user pragmatism, governance and handling of RM, risk, and benefit, and scientific interests. The priority of interests varied across the six countries, and the variations may be influenced by the political, social, cultural, and media contexts of SCR and RM in each country.
    UNASSIGNED: The implications can contribute to a deeper understanding of the diversity of public attitudes, and bring about an appropriate examination of a wide range of ethical and social concerns of SCR and RM in global contexts.

    背景:抑郁症和神经认知障碍是导致全球残疾的主要原因。然而,在日常临床实践中没有客观或容易获得的生物标志物,这导致评估治疗反应和开发新药物的困难。新技术可以量化临床医生认为反映疾病严重程度的特征,比如面部表情,语音/语音信息,身体运动,日常活动,和睡眠。
    方法:重度抑郁症,双相情感障碍,主要和次要神经认知障碍以及健康对照者被招募用于研究。精神科医生/心理学家在随访的五年内与参与者进行10分钟的对话访谈≤10次。使用RGB和红外摄像机记录采访,和阵列麦克风。作为一种选择,参与者被要求在观察期间佩戴腕带式装置.各种软件用于处理原始视频,声音,红外线,和可穿戴设备数据。机器学习方法用于预测症状的存在,严重程度,以及症状的改善/恶化。
    结论:这项拟议研究的总体目标,使用计算精神病学技术的客观措施项目(PROMPT),是发展目标,非侵入性,和易于使用的生物标志物,用于评估抑郁症和神经认知障碍的严重程度,以期指导临床决策并降低临床试验失败的风险。挑战可能包括样品的大可变性,这使得很难提取通常反映疾病严重程度的特征。

    BACKGROUND: Depressive and neurocognitive disorders are debilitating conditions that account for the leading causes of years lived with disability worldwide. However, there are no biomarkers that are objective or easy-to-obtain in daily clinical practice, which leads to difficulties in assessing treatment response and developing new drugs. New technology allows quantification of features that clinicians perceive as reflective of disorder severity, such as facial expressions, phonic/speech information, body motion, daily activity, and sleep.
    METHODS: Major depressive disorder, bipolar disorder, and major and minor neurocognitive disorders as well as healthy controls are recruited for the study. A psychiatrist/psychologist conducts conversational 10-min interviews with participants ≤10 times within up to five years of follow-up. Interviews are recorded using RGB and infrared cameras, and an array microphone. As an option, participants are asked to wear wrist-band type devices during the observational period. Various software is used to process the raw video, voice, infrared, and wearable device data. A machine learning approach is used to predict the presence of symptoms, severity, and the improvement/deterioration of symptoms.
    CONCLUSIONS: The overall goal of this proposed study, the Project for Objective Measures Using Computational Psychiatry Technology (PROMPT), is to develop objective, noninvasive, and easy-to-use biomarkers for assessing the severity of depressive and neurocognitive disorders in the hopes of guiding decision-making in clinical settings as well as reducing the risk of clinical trial failure. Challenges may include the large variability of samples, which makes it difficult to extract the features that commonly reflect disorder severity.

    在日本,一个由京都大学组成的研究中心网络,提供临床级诱导多能干细胞(iPSC),以及几个主要研究中心,开发基于iPSC的再生疗法,用于iPSC的临床应用.这个网络在一个新成立的资助机构的监督下,日本医学研究与发展机构。并行,日本的监管机构,包括卫生部,劳动和福利,和药品和医疗器械局,正在尝试通过几项举措来加速再生医学产品(RMP)的开发过程:1)根据修订后的《药品和医疗器械法》,引入仅适用于RMP的有条件和有时间限制的批准计划,2)在开发的早期阶段扩大咨询计划,3)建立指南,以支持有效的开发和审查;4)在相关学术团体和专家的合作下,加强上市后的安全措施,例如引入患者登记处并制定用户要求。最终,有人提议在iPSC银行之间建立一个全球网络,从人类白细胞抗原纯合供体中获得临床级iPSC.为了在全球共享临床级iPSC,并促进基于iPSC的RMP的全球开发,有必要促进监管协调,并根据科学证据建立与iPSC和分化细胞相关的共同标准。
    In Japan, a research center network consisting of Kyoto University to provide clinical-grade induced Pluripotent Stem Cells (iPSC) and several major research centers to develop iPSC-based regenerative therapies was formed for the clinical application of iPSCs. This network is under the supervision of a newly formed funding agency, the Japan Agency for Medical Research and Development. In parallel, regulatory authorities of Japan, including the Ministry of Health, Labour and Welfare, and Pharmaceuticals and Medical Devices Agency, are trying to accelerate the development process of regenerative medicine products (RMPs) by several initiatives: 1) introduction of a conditional and time-limited approval scheme only applicable to RMPs under the revised Pharmaceuticals and Medical Devices Act, 2) expansion of a consultation program at the early stage of development, 3) establishment of guidelines to support efficient development and review and 4) enhancement of post-market safety measures such as introduction of patient registries and setting user requirements with cooperation from relevant academic societies and experts. Ultimately, the establishment of a global network among iPSC banks that derives clinical-grade iPSCs from human leukocyte antigens homozygous donors has been proposed. In order to share clinical-grade iPSCs globally and to facilitate global development of iPSC-based RMPs, it will be necessary to promote regulatory harmonization and to establish common standards related to iPSCs and differentiated cells based on scientific evidence.
