挑刺Pomalidomide的临床试验

最近Pomalidomide的上市使celgene公司火了一把。关键的3期研究MM-003的细节还没有公布,不过我对这个试验存在一些疑问:

这项研究的试验组是Actimid + 低剂量Dex,对照组则单独给予大剂量的Dex。如果对照组给予Lenalidomide + 低剂量的Dex,情况会是怎么样?

关键在于入组患者的定义,在clinicaltrials.gov上的注册信息,其中有一条是:

· All subjects musthave failed treatment with both lenalidomide and bortezomib in one of thefollowing ways: 1) Documented progressive disease on or within 60 days of completing treatment with lenalidomide and/or bortezomib, or 2) In case ofprior response [≥ partial response (PR)] to lenalidomide or bortezomib,subjects must have relapsed within 6 months after stopping treatment with lenalidomide and/or bortezomib-containing regimens, or 3) Subjects who have not had a ≥ minimal response (MR) and have developed intolerance/toxicity after a minimum of two cycles of lenalidomide- and/or bortezomib-containing regimen

实际如何操作尚不清楚,符合各个条件的患者比例如何。为什么第二点要限定6个月?请园里懂MM临床治疗指南的战友解读解读。

即使患者经过Lenalidomide治疗“refractory”,但是并不说明持续给药Lenalidomide + Dex不能带来好处,否则,为什么在这项研究中,对照组患者单独给予大剂量Dex观察到了PFS呢?
