雄激素受体(AR)仍是去势抵抗性前列腺癌(mCRPC)的核心靶点,但临床实践已逐步超越传统 AR 通路抑制剂(ARPI),AR 扩增、突变、剪接变体及重排等改变在 mCRPC 中高度富集,常预示预后较差。
本次 ESMO 2026 报告的 JNJ-6143 一期试验(n=105)确立推荐二期剂量(RP2D)为 50 mg 口服,该剂量下任何级别治疗相关不良事件(TRAE)发生率低于 60%,PSA50 达 77%、PSA90 达 48%,确认客观缓解率(ORR)为 69%,且高 PSA 缓解率不受高危分子特征影响,中位缓解持续时间 11 个月。
会后媒体跟进披露:BioSpace 指出在 16 例经影像确认可测量疾病的患者中 12 例缓解,ORR 为 75%;中文产业新闻同步确认 ORR 75%,并补充强生以 30.5 亿美元收购 Halda Therapeutics,JNJ-6143 原代号 HLD-0915,为 RIPTAC 平台首个进入临床的分子。
该数据标志着首创口服 AR 靶向 RIPTAC 通过招募 BRD4 诱导 AR 降解的新机制在重度预治疗 mCRPC 中显示临床活性,且覆盖高危分子亚型;局限在于仍处一期、可测量病灶样本量小、长期安全性与耐药机制待二期进一步验证。

Totally novel MOA was well tolerated, oral pill and produced significant benefit for pts (PSA90 50%, ORR 68%). P2 trial active now and more coming. Lots of potential!
