Eur J Cancer:转移去势难治性前列腺癌中,二线药物奥拉他单抗组合米托蒽醌/强的松与米托蒽醌/强的松单独治疗效果比较

2019-01-07 AlexYang MedSci原创

血小板来源的生长因子受体-α(PDGFRα)在原发性前列腺恶性肿瘤中表达,并且与骨转移相关。奥拉他单抗是一种完全的人类单克隆抗体,能够结合PDGFRα和阻断下游信号途径。最近,有研究人员评估了奥拉他单抗结合米托蒽醌/强的松(M/P)与M/P单独治疗对转移去势难治性前列腺癌(mCRPC)患者治疗的效果和安全性。研究包括了123名患者,并随机将63名和60名患者分别分配到奥拉他单抗+ M/P和M/P治

血小板来源的生长因子受体-α(PDGFRα)在原发性前列腺恶性肿瘤中表达,并且与骨转移相关。奥拉他单抗是一种完全的人类单克隆抗体,能够结合PDGFRα和阻断下游信号途径。最近,有研究人员评估了奥拉他单抗结合米托蒽醌/强的松(M/P)与M/P单独治疗对转移去势难治性前列腺癌(mCRPC)患者治疗的效果和安全性。

研究包括了123名患者,并随机将63名和60名患者分别分配到奥拉他单抗+ M/P和M/P治疗组。平均的无进展生存均值在奥拉他单抗+ M/P组和M/P组分别为2.3个月和2.4个月(HR= 1.29; 95%CI = 0.87-1.90),另外,平均的OS分别为14.2个月何12.8个月(HR = 1.08; 95% CI = 0.72-1.61)。2个治疗组均具有相似的毒性情况;中性粒细胞减少(24 vs 15%)、贫血(13% vs 14%)和疲劳(11% vs 9%)为最常见的事件。另外,高循环肿瘤细胞数目(CTC)在2个试验中均与不良OS相关。那些具有很高细胞数目的患者(>37/7.5ml)在奥拉他单抗结合米托蒽醌/强的松治疗中表现出了改善的OS。

最后,研究人员指出,奥拉他单抗结合米托蒽醌/强的松治疗的安全性可以接受,但是并没有改善M/P化疗的治疗效果。研究人员指出还需要进一步的研究。
