关注并星标CPHI制药在线 近日，杭州圣域生物（SynRx Therapeutics）自主研发的创新药物SYN818片的新药临床试验申请（IND）获得美国FDA的许可，即将启动1期临床试验。就在几日前，SYN818片在中国的IND申请也获得国家药监局药品评审中心（CDE）的受理。 SYN818是由圣域生物自主研发的一款新型小分子抑制剂化合物。该药物通过精准靶向DNA聚合酶θ（Polθ），有效抑制肿瘤细胞的DNA损伤修复，从而有选择性的杀死肿瘤细胞。临床前研究显示，SYN818能够高效抑制Polθ蛋白活性，阻断MMEJ修复通路，与同源重组缺陷（HRD）存在联合致死效果，从而发挥抗肿瘤作用。同时，它在体内外研究中也表现出与PARPi的显著联合增效作用。SYN818在临床前研究中表现出强效抗肿瘤活性、优异的药代动力学性质，以及良好的安全性，未观察到显著的血液毒性。 根据临床前研究数据，SYN818作为一个Polθ抑制剂具有潜在“best-in-class”的特征。SYN818不仅对HRD肿瘤细胞具有单独成药的潜力，还具有与PARP抑制剂、放化疗、抗体偶联药物等联合用于多种肿瘤治疗的潜质，有望降低现有治疗方案的临床毒性、克服耐药，具有广阔的临床开发前景。 此外，圣域生物的另一款处于临床前阶段的高潜力Polθ抑制剂也在今年4月举办的美国癌症研究协会年会（AACR 2024）上亮相， 其与PARP抑制剂联用具有强大的协同作用，亦可能单独治疗HR通路缺陷的患者。在非临床研究阶段，SYX1097展现了出色的动物体内疗效，优良的药代动力学特征及理想的安全性表现，在较高剂量下亦未见明显血液毒性，从而揭示了宽广的治疗窗。 合成致死靶点之Polθ Polθ是DNA聚合酶A家族成员之一，由哺乳动物细胞中的POLQ基因编码，具有N端解旋酶样结构域和C端DNA聚合酶结构域，通过非结构中心结构域分离开。Polθ是MMEJ途径的重要组成部分，作为效应蛋白参与DNA双链断裂修复。MMEJ生化步骤中，Polθ解旋酶活性促进含有微同源性(互补DNA序列的短片段)的ssDNA退火，Polθ聚合酶活性完成DNA合成填充切除的缺口。在具有功能性HR修复途径的正常细胞中，Polθ参与的MMEJ途径是不活跃的，其对DSB修复的影响有限。HR和MMEJ途径共享相同的底物，同源重组缺陷(HRD)的肿瘤细胞存活会高度依赖MMEJ介导的DNA修复。因此，在HRD肿瘤中抑制Polθ可以诱发合成致死。 此外，PARP作为损伤感应器与Polθ作为效应蛋白均参与HR受损后的MMEJ后备修复通路，由于其不同的作用机制，PARPi和Polθ抑制剂联合治疗可能在HR缺陷肿瘤中具有协同作用；另外，尽管PARPi单药治疗在BRCA突变的癌症中观察到了显著的临床获益，但相当一部分患者产生原发性(＞40％)和继发性耐药，因此需要新的治疗策略来克服PARP的耐药性，以及利用其他的DNA修复缺陷新途径。 鉴于Polθ在正常组织中的几乎不表达，但在乳腺癌、卵巢癌、头颈肿瘤和肺癌等多种肿瘤中高表达，而这些瘤种中又普遍存在同源重组修复缺陷, Polθ被认为是合成致死药物研发的潜力靶点。 Polθ抑制剂：Artios、IDEAYA领衔，国内紧跟脚步 目前，Polθ已经被证实与肿瘤的形成、肿瘤细胞放射治疗的敏感性以及患者预后有关。全球药企针对该靶点有多款新药在研，在研Polθ抑制剂进展缓慢，最快处于1/2期临床，大多处于临床前阶段。从布局企业来看，Polθ抑制剂研发企业并不多，且相对集中。 Artios Pharma是Polθ领域的大玩家，ART4215是Artios开发的一种选择性的口服生物可利用的POLQ聚合酶结构域小分子抑制剂，也是全球首 个Polθ抑制剂，2022年已启动ART4215联合PARP抑制剂他拉唑帕利治疗BRCA缺陷型乳腺癌的2期研究。来自第一阶段的剂量组初步数据表明，ART4215具有良好的耐受性。此外，Artios还布局2款Polθ抑制剂，ART6043处于临床1/2期；ART558和ART812处于临床前。 IDEAYA Biosciences是一家致力于突破合成致死领域技术困境的创新企业。2020年6月，IDEAYA Biosciences和葛兰素史克公司（GSK）宣布在“合成致死”领域建立战略合作伙伴关系，而这一战略合作伙伴关系包含IDEAYA Biosciences的三个合成致死研发项目，分别靶向MAT2A、Polθ和Werner解旋酶。 GSK101（IDE705）是一种潜在首 创Polθ小分子抑制剂。临床前研究显示，在BRCA突变模型中，GSK101联用niraparib与单药相比，能产生更深入、更持久的抗肿瘤作用。去年8月，该药在美国获批1/2期临床，评估其联合GSK的PARP小分子抑制剂niraparib治疗携带BRCA或其他同源重组（HR）突变或同源重组缺陷（HRD）肿瘤的效果。 此外，有研究指出一种在20世纪50年代发现的抗生素新生霉素（novobiocin，NVB）也是一种人类DNA聚合酶Polθ的抑制剂，能有效地杀死携带同源重组（HR）DNA修复缺陷的肿瘤细胞，更加令振奋的是，这种杀伤能力对那些对PARP抑制剂产生耐药的肿瘤细胞也有效。2023年1月，美国食品和药物管理局（FDA）批准Novobiocin用于携带BRCA2或BRCA1基因突变的癌症患者的临床试验。 除了圣域生物，国内药企如先声药业也积极布局了该靶点，已经有2款Polθ抑制剂处于临床前阶段，分别为SIM0508和SS008871。其中，SIM0508能够抑制HR缺陷的BRCA2-/-DLD-1细胞的增殖，并显示出DLD-1亲本细胞和非恶性细胞的>125倍选择性，SIM0508片的临床试验申请在今年6月已获得CDE受理。另一款Polθ抑制剂SS008871和奥拉帕尼的组合能进一步导致肿瘤消退，且在人类造血干细胞等体外试验中没有出现明显的造血毒性风险，具有良好的安全性。 参考文献： 1.Zhou, J., et, al.
