概括
这项研究发现,表观遗传和转录药物 (RAdR) 的组合在复发/耐药T细胞淋巴瘤 (r/r TCL) 患者中表现出活性,但没有导致持久缓解. 组合疗法有助于将一些患者通向移植等进一步治疗的桥梁.
科学领域:
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
- 遗传学 是一个遗传学.
背景情况:
- 复发性/难治性T细胞淋巴瘤 (r/r TCL) 的治疗选择有限.
- 在TCL中,表观遗传和转录调节的遗传突变很常见.
- 向疗法和表观遗传调节器在TCL中显示出协同作用的潜力.
研究的目的:
- 评估一种新型组合疗法 (RAdR) 对r/rTCL的安全性和有效性.
- 为了确定 lenalidomide 与罗米德素,阿扎西提丁和德克萨米他联合的最大耐受剂量 (MTD).
- 评估反应率,生存率和免疫激活标记.
主要方法:
- 一期临床试验,增加莱纳利多米德的剂量增加到罗米德素,阿扎西提丁和德克萨米 (RAdR).
- 主要终点:莱纳利多米德的MTD.
- 二级终点:客观应答率 (ORR),无进展生存率 (PFS),总生存率 (OS) 和免疫标记.
- 在细胞系模型中探索药物组合活性.
主要成果:
- 莱纳利多米德的MTD被确定为20毫克.
- 在MTD (n=9) 治疗的患者中,ORR为89%,完全响应率为22%.
- 在19%和21%的周期中,分别观察到3-4级血小板缩和中性质减退.
- 一年后,PFS为14%,OS为66%.
- RAdR组合显示出活性,但没有诱导持久的反应.
结论:
- 在高度耐火性TCL的患者中,RAdR组合是活跃的.
- 虽然没有治愈,但该方案可以将患者连接到整合疗法,如全基因移植.
- 需要对TCL的表观遗传和转录药物组合进行进一步的研究.

Treatment Resistant Cancers
3.8K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Clinical Trials: Overview
5.2K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...
