研究的目的:
- 评估TQB3602在RRMM患者中的安全性,耐受性,药理动力学和初步疗效.
- 为了确定TQB3602在这个患者群体中的最大耐受剂量 (MTD).
主要方法:
- 一个多中心,I期,3+3剂量升级和扩展临床试验.
- 招募RRMM患者,他们之前至少接受过两种抗髓瘤疗法.
- TQB3602在28天周期的第1,8和15天内口服0.5-7mg剂量.
主要成果:
- 25名RRMM患者被纳入剂量升级阶段.
- 由于7.0mg的剂量限制性毒性 (周围神经病变,腹),MTD被确定为6.0mg.

Treatment Resistant Cancers
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...
