CytomX Therapeutics (NasdaqGS:CTMX) FY Conference Transcript
2025-09-11 02:07
公司概况 * CytomX Therapeutics是一家专注于肿瘤学的生物制剂公司 开发名为Probody Therapeutic Platform的抗体掩蔽技术平台 旨在改善高效抗癌药物如抗体药物偶联物(ADC)或T细胞衔接器的治疗窗口[4] * 公司目前有两个临床阶段项目:靶向EPCAM的掩蔽ADC CX-2051 和掩蔽版干扰素α2B CX-801[4] 核心技术:Probody掩蔽平台 * 该技术通过在抗体或其他生物制剂上工程化添加短而高度特异性的肽来掩蔽它们 从而阻断其与靶点结合的能力 直到掩蔽物被移除[5] * 掩蔽物的移除由肿瘤相关蛋白酶在癌组织中特异性和选择性实现 利用肿瘤组织与正常组织之间蛋白酶水平的差异实现药物局部激活[5] * 此技术能够针对在肿瘤组织中非常丰富但因在正常组织中存在而难以成药的创新靶点 通过偏向肿瘤组织而非正常组织来打开治疗窗口[6] * ADC是该技术的重要支柱应用之一[6] 核心产品CX-2051 (EPCAM ADC) **靶点特征与未满足需求** * EPCAM是一个长期存在的靶点 在结直肠癌(CRC)细胞表面高度表达 达到类似HER2的水平 即每个细胞有数百万拷贝 并且在几乎所有CRC患者中表达一致且均匀[8] * 然而 EPCAM作为一种上皮细胞粘附分子 存在于体内的所有上皮结构中 其正常组织表达导致过往靶向策略出现毒性(如胰腺炎 肝毒性 特定胃肠道毒性) 限制了系统性给药的抗EPCAM药物成功进入临床[8] * 局部给药的EPCAM策略(如膀胱内给药的毒素融合蛋白 腹膜腔给药的CD3 EPCAM双特异性)已显示有效性 证明了若能将有有效载荷的EPCAM抗体递送至肿瘤 它可以有效 CX-2051的掩蔽策略旨在系统性实现这一点[9][10] **临床数据(截至2025年5月)** * 研究设计:专注于CRC患者的1期研究 剂量水平从2.4 mg/kg至10 mg/kg 每三周给药一次 患者群体为晚期经治(中位既往治疗线数为4)[15][16] * 疗效:在18名可评估疗效患者中 确认的客观缓解率(ORR)为28% 疾病控制率(DCR)为94% 初步评估的中位无进展生存期(mPFS)为5.8个月[16][17] * 对比:当前四线标准治疗的ORR为1%-2% PFS为3.5个月 显示出巨大进步和极具竞争力的潜力[16][17] * 安全性:迄今为止未出现剂量限制性毒性 血液学毒性可控(低发生率的3级贫血和中性粒细胞减少) 未见胰腺毒性或胰腺酶水平调制 也未见肝毒性信号 主要需关注的AE是胃肠道毒性[17][18][27][28] * 胃肠道毒性:约20%的安全性可评估患者(25名)出现3级腹泻 这与TOPO-1抑制剂的预期一致 公司已实施洛哌丁胺预防策略进行管理[20][31][32] * 严重不良事件:发生一例5级治疗相关不良事件 患者经历胃肠道毒性后发展为急性肾损伤 最终不幸去世 安全审查委员会认为这可能是一个异常个案 与研究中的其他混杂临床因素(如患者曾捐肾)有关 研究继续进行 仅排除了曾有捐肾史的患者[36][37][38] **最新进展与未来计划** * 三个剂量水平(7.2, 8.6, 和 10 mg/kg)的扩展队列已完成入组 每个队列约20名患者 数据预计在2026年第一季度更新[22][23][41] * 届时将评估各剂量水平的缓解率 PFS 暴露量-剂量反应关系 以及AE管理策略的效果 以选择后续研究的剂量[23][42] * 预计2026年启动下一项研究 可能是一项在四线CRC中与医生选择或fruquintinib对比的随机研究 可能推进两个剂量 并可能基于PFS终点获得加速批准[46][47] * 长远计划包括探索联合疗法(如与贝伐珠单抗或化疗联用)并向更前线治疗推进 目标是最终用CX-2051替代伊立替康[50] * EPCAM在几乎所有实体瘤中都有表达 公司愿景是让CX-2051成为一种泛肿瘤治疗药物[51] **市场潜力** * 仅在美国 每年至少有12,000名患者在四线接受治疗 即使在四线也有成为重磅药物的潜力(fruquintinib上市头几年表现良好)[48] 其他研发管线CX-801 * CX-801是掩蔽版本的干扰素α2B 一种免疫疗法 旨在使"冷"肿瘤变"热"并恢复对检查点抑制的反应性[52] * 正在黑色素瘤中进行1期研究 已通过多个单药递增队列 耐受性良好 并于第二季度开始与Keytruda联合给药[52] * 计划在2025年第四季度分享单药治疗组的转化生物标志物数据(如干扰素应答基因的调节 肿瘤微环境中细胞群的 modulation) 为联合疗效奠定基础 临床数据计划在2026年公布[52][53] 公司战略与财务 * 公司于2025年5月数据披露时成功进行了融资[56] * 认识到CX-2051项目将有重大的资本需求 正在仔细考虑未来的资本形成策略[56] * 同时也在考虑为CX-2051寻求合作伙伴关系的适当时机 因为其有潜力迅速成为一个非常广泛的项目 预计会吸引战略方的浓厚兴趣[57]
