Preclinical Evaluation of JAB-2485, a Potent AURKA Inhibitor with High Selectivity and Favorable Pharmacokinetic Properties

Article

作者: Chen, Mingming ; Yang, Guiqun ; Cheng, Dai ; Lin, Yiwei ; Wang, Yanping ; Wang, Yinxiang ; Li, Haijun ; Hu, Shizong ; Sun, Xin

As a critical mitotic regulator, Aurora kinase A (AURKA) is aberrantly activated in a wide range of cancers. Therapeutic targeting of AUKRA is a promising strategy for the treatment of solid tumors. In this study, we evaluated the preclinical characteristics of JAB-2485, a small-molecule inhibitor of AURKA currently in Phase I/IIa clinical trial in the US (NCT05490472). Biochemical studies demonstrated that JAB-2485 is potent and highly selective on AURKA, with subnanomolar IC₅₀ and around 1500-fold selectivity over AURKB or AURKC. In addition, JAB-2485 exhibited favorable pharmacokinetic properties featured by low clearance and good bioavailability, strong dose-response relationship, as well as low risk for hematotoxicity and off-target liability. As a single agent, JAB-2485 effectively induced G2/M cell cycle arrest and apoptosis and inhibited the proliferation of small cell lung cancer, triple-negative breast cancer, and neuroblastoma cells. Furthermore, JAB-2485 exhibited robust in vivo antitumor activity both as monotherapy and in combination with chemotherapies or the bromodomain inhibitor JAB-8263 in xenograft models of various cancer types. Together, these encouraging preclinical data provide a strong basis for safety and efficacy evaluations of JAB-2485 in the clinical setting.

Potent bromodomain and extraterminal domain inhibitor JAB-8263 suppresses MYC expression and exerts anti-tumor activity in colorectal cancer models

Article

作者: Yang, Gui-Qun ; Xia, Shao-You ; Long, Wei ; Du, Xiao-Hui ; Liu, Xin-Mo ; Li, Hai-Jun ; Li, Song-Yan ; Sun, Wen

BACKGROUND:

The overexpression of the MYC gene plays an important role in the occurrence, development and evolution of colorectal cancer (CRC). Bromodomain and extraterminal domain (BET) inhibitors can decrease the function BET by recognizing acetylated lysine residues, thereby downregulating the expression of MYC.

AIM:

To investigate the inhibitory effect and mechanism of a BET inhibitor on CRC cells.

METHODS:

The effect of the BET inhibitor JAB-8263 on the proliferation of various CRC cell lines was studied by CellTiter-Glo method and colony formation assay. The effect of JAB-8263 on the cell cycle and apoptosis of CRC cells was studied by propidium iodide staining and Annexin V/propidium iodide flow assay, respectively. The effect of JAB-8263 on the expression of c-MYC, p21 and p16 in CRC cells was detected by western blotting assay. The anti-tumor effect of JAB-8263 on CRC cells in vivo and evaluation of the safety of the compound was predicted by constructing a CRC cell animal tumor model.

RESULTS:

JAB-8263 dose-dependently suppressed CRC cell proliferation and colony formation in vitro. The MYC signaling pathway was dose-dependently inhibited by JAB-8263 in human CRC cell lines. JAB-8263 dose-dependently induced cell cycle arrest and apoptosis in the MC38 cell line. SW837 xenograft model was treated with JAB-8263 (0.3 mg/kg for 29 d), and the average tumor volume was significantly decreased compared to the vehicle control group (P < 0.001). The MC38 syngeneic murine model was treated with JAB-8263 (0.2 mg/kg for 29 d), and the average tumor volume was significantly decreased compared to the vehicle control group (P = 0.003).

CONCLUSION:

BET could be a potential effective drug target for suppressing CRC growth, and the BET inhibitor JAB-8263 can effectively suppress c-MYC expression and exert anti-tumor activity in CRC models.

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.
