感谢楼主关于Rova-T靶向实验的分享,今天我也看了这篇paper,对一些相关的临床数据作些补充,希望能给大家一些参考。
具体的实验方案楼主已经给出了比较详实的数据,我主要会对受体的身体状况和实验结果作些补充(数据均从paper中获得)
Further inclusion criteria were:
Eastern Cooperative Oncology Group(ECOG) performance status of 0 or 1; minimum life expectancy of 12 weeks; and adequate haematological counts and hepatic and renal function.
患者受体要求:根据ECOG评分为0或1,并且经评估最低存活时间为12周及以上,血常规良好(具体为各项细胞计数充分),肝肾功能健全。
具体数据:
Age (years) 61 (55–69) (平均年龄61)
Sex
Female 32 (43%) (女性32,占43%)
Male 42 (57%)(男性42,占57%)
ECOG performance score (ECOG评分)
0 21 (28%) (0分:21人,占28%)
1 50 (68%)(1分:50人, 占68%)
2 3 (4%)(2分:3人,占4%)
Previous lines of treatment (之前接受过的铂类治疗方案)
One 39 (53%) (一线:39人,占53%)
Two 35 (47%)(二线:35人,占47%)
Tumour DLL3 expression§ (肿瘤的DLL3表达)
≥1% 42/48 (88%) (48人中有42人表达≥ 1%, 占88%)
≥50% 32/48 (67%) (48人中有32人表达≥ 50%,占67%)
Attention:这里分母(总人数)为什么是48人,因为实验受体中只有48人能提供有效的肿瘤组织进行检验。
DLL3-high patients also had a longer treatment duration and follow-up (mean 7·6 months [SD 6·0]) than did those with DLL3-low expression (2·9 months [2·4]).
实验结果显示,具有DLL-3高表达的患者普遍拥有一个比较长的治疗周期(平均7.6月),相比较而言,DLL-3低表达的患者治疗周期较短(平均2.9月)
65 (79%) of 82 patients died during the study, 56 (86%) because of disease, four (6%) because of an adverse event, four (6%) for unknown reasons, and one (2%) because of a bleeding ulcer (appendix p 27; data corresponding to the end-of-study forms are missing for two patients who
discontinued because of an adverse event and have died).
实验结果:82人(小细胞74例,大细胞8例)中65人在实验周期中死亡,56人(86%)由于疾病死亡,4人(6%)由于药物副作用死亡,4人(6%)由于不明原因死亡,1人(2%)由于出血性溃疡死亡。
以上是这个research中比较有价值的数据,我把它提炼出来供想了解DLL-3的小细胞家属们参考,不过由于这款药在美国还处于临床试验阶段,离上市估计还有一段路要走,当然国内上市还有更长的路要走。Anyway,新药的研发给了小细胞家属一些希望,we are waiting for the bright future! Stay alive!
