别名

enhancer of zeste (Drosophila) homolog 1、enhancer of zeste 1 polycomb repressive complex 2 subunit、Enhancer of zeste homolog 1

+ [6]

简介

Polycomb group (PcG) protein. Catalytic subunit of the PRC2/EED-EZH1 complex, which methylates 'Lys-27' of histone H3, leading to transcriptional repression of the affected target gene. Able to mono-, di- and trimethylate 'Lys-27' of histone H3 to form H3K27me1, H3K27me2 and H3K27me3, respectively. Required for embryonic stem cell derivation and self-renewal, suggesting that it is involved in safeguarding embryonic stem cell identity. Compared to EZH2-containing complexes, it is less abundant in embryonic stem cells, has weak methyltransferase activity and plays a less critical role in forming H3K27me3, which is required for embryonic stem cell identity and proper differentiation.

Background:
Head and neck squamous cell carcinoma (HNSCC) is the 6th most common cancer worldwide. These cancers have different causes, with smoking/tobacco exposure and human papilloma virus infection being the most common. . When HNSCC occurs in people who are not infected with HPV, the cancers are more likely to return after treatment; when this happens, overall survival is only about 10 months, thus better treatments are needed.
Objective:
To test a combination treatment using 2 drugs (valemetostat and pembrolizumab) in people with HNSCC. Phase 1b of the study will determine a recommended dose of the 2 drugs and evaluate how safe the combination is.; this will include patients with HPV-positive and HPV-negative HNSCC, as well as squamous cell NSCLC that have progressed on anti-PD-1/anti-PD-L1 therapies.Phase II will determine how effective the combination is and will focus on patients with HPV-negative HNSCC.
Eligibility:
People aged 18 years and older with HPV-negative HNSCC, sinonasal carcinoma of the head and neck, or squamous non-small cell lung cancer (NSCLC).
Design:
Participants will be screened. They will have a physical exam. They will have blood and urine tests and tests of their heart function. They will have imaging scans. They may have a biopsy: A small sample of tissue will be removed from the tumor.
Treatment will be given in 21-day cycles.
Pembrolizumab is administered through a tube attached to a needle inserted into a vein in the arm. Participants will receive pembrolizumab on the first day of each cycle.
Valemetostat is a tablet taken by mouth. Participants will take the tablet once a day at home. They will record the date and time of each dose in a diary. They will also write down any adverse effects they experience.
Participants may remain in the study up to 2 years.

A novel EZH1/2 dual inhibitor inhibits GCB DLBCL through cell cycle regulation and M2 tumor-associated macrophage polarization

Article

作者: Sun, Hongtao ; Xu, Fang ; An, Ran ; Zhang, Zhimeng ; Li, Yuqing ; Lin, Yueling ; Zhang, Dongli ; Liu, Zhong ; Li, Manmei

The incidence of germinal center B-cell-like type diffuse large B-cell lymphoma (GCB DLBCL) is steadily increasing, with a known hereditary component. Although some molecular mechanisms in GCB DLBCL have been elucidated, understanding remains incomplete, limiting the effectiveness of targeted therapies. In GCB DLBCL patients, abnormally high expression of zeste homologs 2 (EZH2) is noted, and the compensatory effect of EZH1 following EZH2 inhibition contributes to poor prognosis. This highlights the potential of dual targeting of EZH1/2 as a promising strategy. In this study, we developed a novel inhibitor, EZH-1-P2, targeting EZH1/2 and evaluated its antitumor effects on DLBCL cells. Mechanistically, inhibition of EZH1/2 affects the epigenetic regulation of gene expression related to p53, impacting cell cycle progression and GCB DLBCL cell growth. Additionally, while EZH1/2 inhibition impacts NOTCH signaling, the precise mechanism by which it affects M2-type tumor-associated macrophage polarization and germinal center expansion requires further investigation. Our research introduces EZH-1-P2 as a novel inhibitor with potential as a candidate for GCB DLBCL therapy, although further studies are needed to fully elucidate its mechanisms.

作者: Song, Minchul ; Jang, Jinsun ; Son, Heejun ; Kim, Yoo Hyung ; Cho, Sun Wook ; Park, Seung Shin ; Choi, Hye-Mi ; Chai, Young Jun ; Chung, Woosung ; Oh, Moon Young ; Park, Young Joo

Background: We explored the utility of a small multi-gene DNA panel for assessing molecular profiles of thyroid nodules and influencing clinical decisions by comparing outcomes between tested and untested nodules.Methods: Between April 2022 and May 2023, we prospectively performed fine-needle aspiration (FNA) with gene testing via DNA panel of 11 genes (BRAF, RAS [NRAS, HRAS, KRAS], EZH1, DICER1, EIF1AX, PTEN, TP53, PIK3CA, TERT promoter) in 278 consecutive nodules (panel group). Propensity score-matching (1:1) was performed with 475 nodules that consecutively underwent FNA without gene testing between January 2021 and December 2021 (control group).Results: In the panel group, positive call rate for mutations was 41.7% (BRAF 16.2%, RAS 12.6%, others 11.5%, double mutation 1.4%) for all nodules, and 40.0% (BRAF 4.3%, RAS 19.1%, others 15.7%, double mutation 0.9%) for indeterminate nodules. Benign call rate was 69.8% for all nodules, and 75.7% for indeterminate nodules. In four nodules, additional TP53 (in addition to BRAF or EZH1) or PIK3CA (in addition to BRAF or TERT) mutations were co-detected. Sensitivity, specificity, positive predictive value, and negative predictive value were 80.0%, 53.3%, 88.1%, 38.1% for all nodules, and 78.6%, 45.5%, 64.7%, 62.5% for indeterminate nodules, respectively. Panel group exhibited lower surgical resection rates than the control group for all nodules (27.0% vs. 52.5%, P<0.001), and indeterminate nodules (23.5% vs. 68.2%, P<0.001). Malignancy risk was significantly different between the panel and control groups (81.5% vs. 63.9%, P=0.008) for all nodules.Conclusion: Our panel aids in managing thyroid nodules by providing information on malignancy risk based on mutations, potentially reducing unnecessary surgery in benign nodules or patients with less aggressive malignancies.

Epigenetic therapies targeting histone lysine methylation: complex mechanisms and clinical challenges

Review

作者: Shilatifard, Ali ; Gold, Sarah

As epigenetic therapies continue to gain ground as potential treatment strategies for cancer and other diseases, compounds that target histone lysine methylation and the enzyme complexes represent a major frontier for therapeutic development. Clinically viable therapies targeting the activities of histone lysine methyltransferases (HKMT) and demethylases (HKDMs) have only recently begun to emerge following FDA approval of the EZH2 inhibitor tazemetostat in 2020 and remain limited to compounds targeting the well-studied SET domain-containing HKMTs and their opposing HKDMs. These include the H3K27 methyltransferases EZH2/EZH1, the singular H3K79 methyltransferase DOT1L, and the H3K4 methyltransferase MLL1/COMPASS as well as H3K9 and H3K36 methyltransferases. They additionally include the H3K4/9-preferential demethylase LSD1 and the H3K4-, H3K27-, and H3K36-preferential KDM5, KDM6, and KDM2 demethylase subfamilies, respectively. This Review discusses the results of recent clinical and preclinical studies relevant to all of these existing and potential therapies. It provides an update on advancements in therapeutic development, as well as more basic molecular understanding, within the past 5 years approximately. It also offers a perspective on histone lysine methylation that departs from the long-predominant "histone code" metaphor, emphasizing complex-disrupting inhibitors and proximity-based approaches rather than catalytic domain inhibitors in the outlook for future therapeutic development.

辉瑞重磅新药启动III期临床研究，有望成为前列腺癌一线疗法EZH2抑制剂！

关注并星标CPHI制药在线近日，中国药物临床试验登记与信息公示平台官方网站予以公示，辉瑞（Pfizer）已然开启了一项国际多中心（涵盖中国）的 III期临床研究，此研究旨在评估 PF -06821497(Mevrometostat)联合恩扎卢胺相较于恩扎卢胺或者多西他赛针对既往经受过醋酸阿比特龙治疗的转移性去势抵抗性前列腺癌患者的疗效及安全性。依据公示内容，该研究计划于国际范围纳入 600 人，在我国国内纳入90人。对于此项研究，辉瑞的愿景是构建全新的一线 mCRPC 标准治疗方案，以延长患者的生存期限。 Mevrometostat乃是辉瑞研发的一款 EZH2 抑制剂，其能够阻断癌细胞中因 EZH2 过度表达所驱动的非正常基因表达，从而致使癌细胞增殖降低、诱导细胞死亡，并且抑制癌细胞的迁移与侵袭，最终实现治疗癌症的目标。在此之前辉瑞宣称，这款药物有希望成为在美国获得批准的首款用于前列腺癌的 EZH2 抑制剂。据今年 3月辉瑞在其肿瘤学创新日期间所披露的情况，到 2030 年其肿瘤学研发管线有望推出超过8 款重磅疗法，当中便包含这一EZH2抑制剂。截图来源：中国药物临床试验登记与信息公示平台官网截图来源：Clinicaltrials官网一、EZH2：癌症治疗的新靶点目前，EZH2已然跻身癌症治疗的前沿靶点队列之中。EZH2属于一种组蛋白甲基转移酶，其异常的表达与众多癌症的发展以及不良预后存在关联，像前列腺癌、乳腺癌、肺癌以及血液恶性肿瘤等均涵盖在内。有研究指出，EZH2的过度表达能够凭借多种作用机制推动癌症的产生和发展，涵盖了使肿瘤抑制基因的表达受到抑制、促使参与细胞增殖以及存活的基因进行表达等。另外，EZH2已获证实能够通过调控参与上皮-间质转化的基因表达来助推癌症转移。举例来讲，他泽司他（tazemetostat）已经获批用于部分类型血液肿瘤的治疗。与此同期，全球范围内尚有众多的EZH2抑制剂正在进行研发工作，用于诊治多种不同类别的肿瘤。 EZH2在引发GBM癌细胞侵袭、迁移和增殖以及维系其干细胞特性的过程里发挥着关键效用。组蛋白的甲基化、乙酰化、泛素化和磷酸化等修饰将DNA编排成核小体，和正常细胞的功能以及肿瘤的发生有所关联。EZH2的过表达或者突变（像是淋巴瘤里的功能获得性突变以及髓系恶性肿瘤里的功能丧失性突变）已经在诸多肿瘤中被确认，使得EZH2成为潜在的治疗目标。已经鉴别出数种调节EZH2的机制，包含miRNA、LncRNA对EZH2mRNA的调节、翻译后的修饰、转录的调控以及通过DNA结合蛋白的DNA可及性。例如，miR-124-3p表达的增高致使mTOR和AKT磷酸化水平下降，而miR-124-3p表达的降低则产生相反效果。研究成果显示，miR-124-3p通过瞄准EZH2抑制前列腺癌的增殖和侵袭进程，同时引导细胞凋亡。 lncRNA被界定为一类长度大概为200个核苷酸、不存在显著蛋白质编码能力的RNA分子。lncRNA和癌症的进展存在关联，例如细胞侵袭、迁移和血管生成以及自噬。比如，已知HOTAIR是不同类别癌症临床结局的预测因子。LnRNA HOTAIR能够作为PRC2和不同组蛋白修饰的模块化支架。研究表明，lncRNA 调节 EZH2 基因的功能和表达。EZH2 还调节参与多种致癌信号通路的几种 lncRNA 的转录。 EZH2信号通路驱动癌症进展，并有可能干扰抗肿瘤免疫反应，因此它作为癌症治疗的有效治疗靶点而受到关注。通过使用EZH2-CRISPR/Cas9，HIF-1α被表观遗传抑制，导致癌症类型的免疫抑制作用停止或减弱。研究结果表明，利用纳米颗粒递送的EZH2 siRNA可以通过下调EZH2表达有效降低肿瘤细胞的侵袭和迁移能力，并可对卵巢癌细胞和肺癌细胞产生协同治疗作用。小发夹RNA是另一种可以在癌症治疗中抑制EZH2存在的RNA干扰。例如，通过shRNA降低EZH2水平可以降低前列腺癌细胞的转移和增殖率。因此，遗传方法为在癌症治疗中靶向和调节EZH2表达提供了一种有希望的途径。EZH2 抑制剂包括 GSK2816126、Tazemetostat、Valemetostat、cPI-0209、SHR2554、MAK683 和 PF-06821497，它们可抑制其功能并恢复致癌转录因子。二、Mevpro临床研究这是一项全球性、多中心且随机的 III期研究（Mevpro-2），用以对Mevrometostat 联合恩杂鲁胺以及安慰剂联合恩杂鲁胺于 mCRPC 患者之中的疗效展开评估，此类患者在被确诊 mCRPC 之后，除了 ADT （雄激素剥夺疗法）和第一代抗雄激素药物之外，未曾接受过其他的全身抗癌治疗。这项临床研究在日本和美国开启。另外，在8 月份，辉瑞于中国、美国等众多国家首次开启了一项有关 Mevrometostat的 III 期研究（MEVPRO-1），将恩扎卢胺联合恩扎卢胺或多西他赛用于既往已接受过醋酸阿比特龙治疗的转移性去势抵抗性前列腺癌患者。对于该研究，其目的在于延长恩扎卢胺的疗效，并取代化疗。截图来源：辉瑞肿瘤创新日资料有关研究指出，EZH2对基因活性起到参与调控的作用，和前列腺癌细胞的增殖存在关联。临床前的相关数据表明，Mevrometostat 能够抑制基因调控，并且和恩扎卢胺具备协同功效。源自辉瑞公开的临床成果，Mevrometostat与恩扎卢胺联合的1 期临床呈现出良好的抗肿瘤活性。在此之中，Mevrometostat联合恩扎卢胺针对既往接受过阿比特龙治疗的 mCRPC 患者，其中位放射学无进展生存期（rPFS）达 17.1 个月，对比以往的数据（中位 rPFS 为4.8个月），获益颇为显著；Mevrometostat联合恩扎卢胺对于既往接受过恩扎卢胺治疗的mCRPC患者，其中位rPFS为 11.7 个月。另外，辉瑞在近日还开启了另外一项 3期的 MEVPRO-2研究，这项研究打算评估 mevrometostat加恩扎卢胺对于未经阿比特龙治疗的转移性去势抵抗性前列腺癌男性患者的作用。针对这一适应症的临床研究申请（IND）也已在中国获得批准，预计很快将会在中国开启。三、多款EZH2抑制剂已获批，但适应症不同据Insight 数据库透露，当下全球已有2种药物成功获批得以上市，然而获批的适应症却各不相同。第一款：益普生研发靶向EZH2 他泽司他，其于2020年率先在美国获得批准，当前已经被批准用于上皮样肉瘤、滤泡性淋巴瘤。在 2024年 7月 4日，这款药于中国提交了上市申请（JXHS2400046），其适应症为 EZH2突变呈阳性且之前接受过至少两种系统性治疗的复发或者难治性滤泡性淋巴瘤(FL)成年患者，预计会在 2025年第二季度获批。第二款：第一三共研发且靶向 EZH1/EZH2 的 Valemetostat，它在2022 年最先于日本获批上市，当前已批准用于成人 T细胞白血病-淋巴瘤、外周 T细胞淋巴瘤；在国内的研发处于批准临床的阶段。辉瑞的 Mevrometostat 在 mCRPC 适应症方面于全球的进展可谓最快，倘若一切顺利，或许会成为全球首款获批用于前列腺癌的 EZH2 抑制剂。国内的企业在 EZH2靶点上也并未落后太多，当下共有 4款国产的EZH2抑制剂迈入了临床阶段。其中恒瑞的进展最为迅速，SHR2554已经进入了III 期临床，其适应症为外周 T 细胞淋巴瘤，该临床被 CDE授予了突破性疗法认定以及特殊审批。参考资料： [1] 中国药物临床试验登记与信息公示平台官网.Retrieved Oct 8，2024.?From http://www.chinadrugtrials.org.cn/index.html [2]Oncology Innovation Day.

Shintani 771P Poster Session Saturday, September 14 About the ADC Portfolio of Daiichi Sankyo The Daiichi Sankyo ADC portfolio consists of seven ADCs in clinical development crafted from two distinct ADC technology platforms discovered in-house by Daiichi Sankyo. The ADC platform furthest in clinical development is Daiichi Sankyo’s DXd ADC Technology where each ADC consists of a monoclonal antibody attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers. The DXd ADC portfolio currently consists of ENHERTU, a HER2 directed ADC, and datopotamab deruxtecan (Dato-DXd), a TROP2 directed ADC, which are being jointly developed and commercialized globally with AstraZeneca. Patritumab deruxtecan (HER3-DXd), a HER3 directed ADC, ifinatamab deruxtecan (I-DXd), a B7-H3 directed ADC, and raludotatug deruxtecan (R-DXd), a CDH6 directed ADC, are being jointly developed and commercialized globally with Merck. DS-3939, a TA-MUC1 directed ADC, is being developed by Daiichi Sankyo. The second Daiichi Sankyo ADC platform consists of a monoclonal antibody attached to a modified PBD payload. DS-9606, a CLDN6 directed PBD ADC, is the first of several planned ADCs in clinical development utilizing this platform. Datopotamab deruxtecan, ifinatamab deruxtecan, patritumab deruxtecan, raludotatug deruxtecan, DS-3939 and DS-9606 are investigational medicines that have not been approved for any indication in any country. Safety and efficacy have not been established.
