对患有 PSMA 阳性前列腺癌且接受或未接受过 177Lu-PSMA 放射性配体治疗的男性患者进行 [225Ac]Ac-PSMA-R2 的 I/II 期、开放标签、多中心研究。 (SatisfACtion)
2026年9月10日 更新者:Novartis Pharmaceuticals
满意度:一项 I/II 期、开放标签、多中心研究 [225Ac]Ac-PSMA-R2,用于治疗经过大量预处理的 PSMA 阳性转移性去势抵抗性前列腺癌 (mCRPC) 且既往有或没有 177Lu 标记 PSMA 的男性-靶向放射配体治疗。
该研究的目的是表征 225Ac-PSMA-R2 在先前接受雄激素受体途径抑制剂治疗的转移性去势抵抗性前列腺癌 (mCRPC) 的男性成年参与者中的安全性、耐受性、药代动力学 (PK) 和抗肿瘤活性在 177Lu 后和 177Lu 前的设置中。
研究概览
详细说明
这是一项开放标签、I/II 期、多中心研究,包含两个治疗组(第 1 组和第 2 组)。 每个组都有一个剂量递增部分,一旦确定每个剂量递增部分的最大耐受剂量/扩展推荐剂量(MTD/RDE),研究将继续在各自组中进行扩展部分。
剂量递增部分将在完善的贝叶斯逻辑回归模型 (BLRM) 方法的指导下建立 225Ac-PSMA-R2 的 MTD/RDE。 适应性 BLRM 将遵循过量控制升级 (EWOC) 原则,以控制未来研究参与者的 DLT 风险。 剂量递增决定将由研究者和诺华在剂量递增会议 (DEM) 期间根据安全性和耐受性信息(DLT 风险的 BLRM 总结)以及 PK 和初步疗效信息做出。
剂量扩展部分将评估抗肿瘤活性(前列腺癌工作组3(PCWG3)修改的RECIST 1.1的总体缓解率(ORR)和前列腺特异性抗原50(PSA50)缓解率),并进一步评估安全性、耐受性,以及 225Ac-PSMA-R2 的 PK。
