A Randomized Phase 2 Trial of ASTX727 +/- Iadademstat in Accelerated/Blast-Phase Philadelphia Chromosome-Negative Myeloproliferative Neoplasms (MPNs)

This phase II trial compares the effect of ASTX727 in combination with iadademstat to ASTX727 alone in treating patients with accelerated or blast phase Philadelphia chromosome negative myeloproliferative neoplasms (MPNs). ASTX727 is a combination of two drugs, cedazuridine and decitabine. Cedazuridine is in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine, making it more available in the body so that decitabine will have a greater effect. Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. Iadademstat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving ASTX727 in combination with iadademstat may be more effective than ASTX727 alone in treating patients with accelerated or blast phase Philadelphia chromosome negative MPNs.

Review

作者: Faraj, Hazem ; Ansari, Soubiya ; Akiki, Susanna Jane ; Najim, Mostafa ; Abu-Tineh, Mohammad ; Ibrahim, Mohamed Izham Mohamed ; Alateeg, Saif ; Alshurafa, Awni ; Yassin, Mohamed A

BACKGROUNDMyeloproliferative neoplasms (MPNs) are hematological disorders characterized by abnormal production of myeloid cells due to genetic mutations. Since 2013, researchers have identified somatic mutations in the Calreticulin (CALR) gene, primarily insertions or deletions, in two Philadelphia chromosome-negative MPNs; essential thrombocytosis (ET) and primary myelofibrosis (PMF), and occasionally in chronic myelomonocytic leukemia (CMML). This study aims to identify the various types of CALR mutations and their impact on CALR-positive MPN patients' clinical manifestations and outcomes.METHODSA single-center retrospective study was conducted. The data was collected from pre-existing records. The study was carried out on Philadelphia-negative MPN patients who were being followed up on at the NCCCR (National Center for Cancer Care and Research) to assess the clinical manifestation and outcome of disease treatment. All patients included, were followed in our center between January 1, 2008, and November 20, 2021.RESULTSA total of 50 patients with CALR-positive MPN were reviewed with a median follow-up of three years (1-11). This cohort included 31 (62%) patients with ET, 10 (20%) patients with PMF, and 9 (18%) patients with prefibrotic myelofibrosis (pre-MF). The study involved 38 (76%) male and 12 (24%) female patients. There were 16 (32%) patients diagnosed before the age of 40, 24 (48%) patients diagnosed between the ages of 40 and 60; and 10 (20%) patients diagnosed after the age of 60. Molecular analysis showed 24 (48%) patients with CALR type 1, 21 (42%) patients with CALR type 2, and 5 (10%) patients with none Type 1, none Type 2 CALR mutations. Two patients have double mutations; 1(2%) with none Type 1, none Type 2 CALR and JAK2 mutations, and 1(2%) with CALR type 1 and MPL mutations. The thrombotic events were 3 (6%) venous thromboembolisms, 3 (6%) abdominal veins thromboses, 2 (4%) strokes, and 4 (8%) ischemic cardiac events. Only 4 (8%) patients progressed to Myelofibrosis and were carrying CALR 1 mutations, and 1 (2%) patient progressed to AML with CALR 2 mutation.CONCLUSIONThe data shows a significant rise in CALR-positive MPN diagnoses in younger people, emphasizing the need for a better assessment tool to improve disease management and reduce complications.

Article

作者: Meanwell, Emily V. ; Bogart, Kathleen R. ; Zuker, Ronald M ; Tran, Khoa D. ; Crabtree, Jordan R. ; Jorge, Miguel D ; Henriquez, Mario A. ; Borschel, Gregory H. ; Boente, Charline S ; Tran, Khoa D ; Borschel, Gregory H ; Zuker, Ronald M. ; Henriquez, Mario A ; Mulenga, Chilando M. ; Bogart, Kathleen R ; Jorge, Miguel D. ; Boente, Charline S. ; Meanwell, Emily V ; Crabtree, Jordan R ; Mulenga, Chilando M

BACKGROUNDMoebius syndrome (MoS), a rare congenital condition caused by the underdevelopment of the sixth and seventh cranial nerves, presents with uni- or bilateral facial paralysis and lateral gaze palsy. Those with MoS often have incomplete eyelid closure (lagophthalmos). This study aimed to investigate the experiences of individuals living with incomplete eyelid closure due to MoS.METHODSParticipants shared their experiences in semi-structured open-ended focus groups during the 2023 MoS Foundation Conference. Data were analyzed thematically using Nvivo. The Terzis and Bruno scoring system was used to grade participant eyelid closure (range: 1 being no eyelid closure with full scleral show to 5 being complete eyelid closure with no scleral show) and blink (from 1 being no blink to 5 being synchronous and complete blink present). Marginal reflex distances 1 and 2 (MRD1 and MRD2) were measured to grade for ptosis and lid retraction, respectively.RESULTSFifteen participants participated in two focus groups, comprising adults (n = 12) and adolescents (n = 3). All participants had lagophthalmos with some scleral show, ptosis, and lid retraction. The median eyelid closure score was 3 (incomplete eye closure with 1/3 scleral showing). Five key themes were identified: social stigma and misunderstanding, daily life impacts, seasonal exacerbations, different attitudes toward surgical intervention between adults and adolescents, and a prevailing sense of self-acceptance regarding their condition.CONCLUSIONIncomplete eyelid closure poses significant social challenges for individuals with MoS, especially around social encounters. Our findings show the importance of developing tailored communication tools to support those living with this facial difference.

一个潜在安全信号，计提8亿美元减值

8个月时间里，一个潜在的安全事件信号，间接造成了8亿美元的减值损失。近日，诺华公布2024Q3财报，前第三季度公司总收入371.64亿美元，同比增长11%。单Q3季度收入128.23亿美元，同比增长10%。值得注意的是，在该份财报中，诺华为其一笔价值29亿美元的收购（MorphoSys）计提了8亿美元的减值损失，而这距离该笔交易过仅8个月时间。收购的重心 pelabresib是全球进展最快的一款BET抑制剂，也是促使诺华收购MorphoSys的主要原因。今年2月初，诺华出价29亿美元收购MorphoSys公司，获得了其核心管线pelabresib。 pelabresib最初由一家名为Constellations公司开发，是一种口服小分子BET抑制剂，旨在抑制MF相关基因的表达，研究表明，BET抑制可以针对多种骨髓纤维化的驱动机制，并且与JAK抑制剂联合治疗可以产生协同效果。2021年6月，MorphoSys以17亿美元收购Constellation公司获得了该管线。事实上，MorphoSys在收购Constellations公司后，也出现了一件有意思的事情，大约一年后，MorphoSys为这笔交易计提了2.5亿美元减值损失，并砍掉了在美国大量的研发工作。 MorphoSys被收购时，公司的管线中只剩下三个项目，分别是已上市的CD19单抗Monjuvi，和剩下两条在研管线pelabresib和tulmimetostat。就在该笔交易公布的同一天，MorphoSys也把Monjuvi的全球权益以2500万美元卖给了Incyte公司。相较于tulmimetostat，Pelabresib进展更快一些，已经推进到临床Ⅲ期阶段了。诺华下定决心收购MorphoSys，很大程度得益于Ⅲ期临床MANIFEST-2的大获成功。 2023年11月，该项临床达到了主要终点目标，即第24周时，66%的pelabresib+Ruxolitinib组MF患者达到SVR35（脾脏体积减少35%以上），约为Ruxolitinib单药组的（35%）近一倍。安全性与既往观察到的安全性一致；没有观察到新的安全性信号，另外，与Ruxolitinib相比，Pelabresib+Ruxolitinib报告的贫血不良事件更少。基于该临床结果，MorphoSys计划在2024年中期在美国和欧洲提交Pelabresib+Ruxolitinib作为MF患者一线治疗的上市申请。可能发展为AML？ Pelabresib被收购后并没有按照MorphoSys原先的上市计划推进，而是一再被推迟，这期间，Pelabresib还报告了一个令人不安的安全信号。今年4月，MANIFEST-2的Pelabresib+ruxolitinib组报告了6例发展为更具侵袭性的急性髓性白血病（AML），而对照组只有2例，随后，MorphoSys便向FDA通报了这些安全信号。根据诺华二季度财报披露，公司认为需要获得48周的随访数据，来确定pelabresib的最终上市计划。然而在获得48周的数据后，诺华又表示，需要更长的随访时间来确定pelabresib获批的监管路径，此外，公司还会根据随访情况，评估是否需要额外的临床试验以支持上市批准，这最终可能会pelabresib的整个上市申请计划推迟数年。关于诺华对MorphoSys的收购，之前还有一个关于未证实的消息，这笔交易似乎包含一个退出条款，即如果Pelabresib被FDA拒绝批准，那么诺华可以退出收购。

晶锐医药可入脑的BET抑制剂获批临床，拥挤赛道是否还有突围机会

关注并星标CPHI制药在线近日，中国国家药监局药品审评中心（CDE）官网公示，晶锐医药1类新药JRD-018片获批临床，拟开发治疗晚期恶性肿瘤。 JRD-018是一款可入脑的BET抑制剂，今年4月已经获美国FDA批准开展1期临床研究。晶锐医药拟开启1期临床试验并将针对晚期实体瘤患者进行招募，继而扩展到血液瘤、脑转移或原发性脑瘤，旨在探索JRD-018在患者中的安全性、耐受性、药代动力学以及初步抗肿瘤活性。体内药效研究结果表明，JRD-018单独使用在脑胶质瘤模型、小细胞肺癌模型、非小细胞肺癌模型、髓性单核细胞白血病模型以及乳腺癌模型中均表现出良好的抗肿瘤活性。在临床前动物模型研究中，JRD-018已显示出良好的对脑转移或原发性脑瘤、恶性脑肿瘤的抑制效果。表观遗传学靶点之BET 溴结构域和超末端结构域（bromodomain and extra terminal domain，BET）属于溴结构域蛋白家族，BET蛋白家族包含四个异构体BRD2、BRD3、BRD4、BRDT，它们的结构相似，在N端有2个串联的溴结构域（BD1和BD2）以及一个超末端结构域（ET）。BD1和BD2识别并结合乙酰化赖氨酸残基，与染色质重塑和基因转录的调控过程相关；ET结构域与多种转录因子相互作用。BET蛋白家族通过溴结构域与乙酰化的染色质结合，从而实现在表观遗传学水平上对基因表达进行调控。 BET蛋白家族在人体内表达广泛，与多种实体瘤和恶性血液性肿瘤、炎症、肥胖、肺纤维化等多种疾病的发生和发展密切相关。如原癌基因Myc在超过一半的肿瘤中过表达，BET抑制剂通过竞争性结合阻止BRD4与染色质结合，进而抑制Myc的转录，从而实现抑制肿瘤的目的。 BET抑制剂是一类新型抗癌药，这类药物在治疗血液癌症如白血病和淋巴瘤方面具有良好的前景。BET抑制剂能够通过阻断BET蛋白的功能从而抑制肿瘤生长。研发BET蛋白选择性抑制剂是目前的新方向。目前，一系列BET抑制剂正在临床试验中检验它们治疗包括白血病、淋巴瘤、脑瘤和骨髓瘤在内的多种癌症的疗效。 BET抑制剂：诺华高调购入，加思科、正大天晴加速推进 BET被认为是抗肿瘤药物研发潜力靶点。目前，全球药企针对该靶点已开发出多款药物，详见下表。在研BET抑制剂大多为小分子化学药，此外还包括蛋白水解靶向嵌合体（PROTACs）。适应症上，BET抑制剂主要被开发用于实体瘤和血液性肿瘤，其中部分还被开发用于治疗炎症性疾病如白癜风等。全球至今还尚无BET抑制剂获批，进度最快的就是MorphoSys的Pelabresib，是首个三期临床试验取得成功的BET抑制剂。MorphoSys围绕该药物布局了骨髓纤维化、恶性外周神经鞘瘤、多发性骨髓瘤等多项适应症。 Pelabrisib是由MorphoSys AG公司研制的first-in-class BET抑制剂，近期Pelabrisib治疗骨髓纤维化III期达到了主要研究终点SVR35（脾脏缩小超过35%），从214例患者的临床数据来看， Pelabrisib与JAK抑制剂芦可替尼联用24周，有65.9%的患者脾脏缩小超过35%，而对照组（芦可替尼与安慰剂）仅有35.2%的患者达到SVR35，实验组的疗效比对照组高30.4%。今年年初，诺华以29亿美元收购MorphoSys AG从而拥有了pelabresib这款BET抑制剂。诺华将基于III期MANIFEST-2研究的积极数据在今年下半年向FDA和EMA提交pelabresib联合芦可替尼治疗骨髓纤维化的上市申请。 ZEN-3694是一种领先的差异化BET抑制剂，被开发联合免疫检查点抑制剂、PARP抑制剂、MEK抑制剂、CDK4/6抑制剂、HDAC抑制剂治疗多种肿瘤。ZEN-3694可以降低BRCA1/2和RAD51等蛋白的DNA修复活性，以提高肿瘤细胞对PARP抑制的敏感性，当前用以治疗转移性去势抵抗性前列腺癌II期临床正在开展中。2019年8月，Zenith Epigenetics 与恒翼生物就该药签订超7800万美元的许可协议，授权恒翼生物获得ZEN-3694在中国（包括中国香港、中国台湾和中国澳门地区）的权益。 JAB-8263是加科思自主研发、具有全球知识产权的小分子BET抑制剂，临床前研究显示其对多种实体瘤和血液瘤均能发挥抗肿瘤作用。从公开数据来看，JAB-8263是同类临床项目中活性最强的BET抑制剂，有望在极低剂量下有效抑制多种肿瘤生长，和Pelabrisib相比具有巨大的差异化优势。目前，加科思正在中美两地开展JAB-8263的多中心、开放性I/IIa期临床研究，适应症涉及白血病及实体瘤。 TQB3617是正大天晴自主研发的一款具有全新化学结构的BET抑制剂，能够通过抑制BET蛋白功能减少c-Myc、NF-κB、Aurora B和BCL-2等致癌基因的异常表达，进而发挥抗肿瘤作用。临床前研究结果显示，TQB3617对BET家族的BRD2、BRD3、BRD4、BRDT蛋白均具有较强的抑制活性。TQB3617用于晚期恶性肿瘤的I期临床试验显示，2例骨髓纤维化患者在治疗第12周结束时，脾脏体积较基线分别缩小13%和30%，展现出潜在的抗骨髓纤维化疗效。在28例接受疗效评估的淋巴瘤中，总缓解率（ORR）为39.3%（11/28），其中4例CR，7例PR。 Trotabresib（CC-90010）是一种新型、口服、可逆性、小分子BET抑制剂，可穿透高级别胶质瘤患者的脑肿瘤组织，临床前研究显示其可增强替莫唑胺（TMZ）的抗肿瘤作用。已公布的1b/2期开放标签、剂量探索研究结果显示：在长期随访中，新诊断胶质母细胞瘤（GBM）患者接受Trotabresib+TMZ辅助治疗或Trotabresib+TMZ+RT（放疗）同步治疗耐受性良好，未出现新的不良反应。结语整体来看，BET是进展相对较慢的一个表观遗传学药物靶点。BET蛋白家族在人体内表达广泛，与多种实体瘤和恶性血液性肿瘤、炎症、肥胖、肺纤维化等多种疾病的发生和发展密切相关，是非常有潜力的药物靶点，全球首个BET抑制剂pelabresib III期临床试验的成功宣告了该靶点的成效性，目前全球围绕BET靶点研发火热，值得一提的是，随着科学技术的发展，BET抑制剂的研发不再局限于小分子化药，已有多家企业、机构研发出BET靶向PROTACs。目前国内药企也积极布局BET靶点，而布局方式除了自主研发，还从外部企业引进，如恒翼生物。期待在药企的不懈努力下，BET靶点可以早日迎来重大突破。参考来源 1.Raajit Rampal, Sebastian Grosicki, Dominik Chraniuk et al.Updated safety and efficacy data from the phase 3 MANIFEST-2 study of pelabresib in combination with ruxolitinib for JAK inhibitor treatment-na?ve patients with myelofibrosis.?JCO?42,?6502-6502(2024).DOI:10.1200/JCO.2024.42.16_suppl.6502 2.2024 ASCO.
