概括
博苏替尼 (bosutinib) 是一种氨酸激酶抑制剂,在慢性髓性白血病患者中显示出免疫相关不良事件 (irAEs) 的高率. 这些事件,包括炎症状况,发生的频率比伊马替尼比更高.
科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
背景情况:
- 博苏替尼 (bosutinib) 是一种氨酸激酶抑制剂 (TKI),用于慢性髓性白血病 (CML) 患者,这些患者对其他TKI有抗性.
- 虽然有效,但博苏替尼针对SRC激酶,包括Lyn,引发了对潜在的免疫相关不良事件 (irAEs) 的担忧.
- 以前的研究将林酶与自身免疫性疾病和狼联系起来.
研究的目的:
- 评估用博苏替尼治疗的患者的炎症和免疫相关不良事件 (irAEs) 的时间调整率 (TAR).
- 描述与博苏替尼治疗相关的IRE类型和发病率.
主要方法:
- 从60名CML患者的临床数据分析,至少三个月的随访.
- 使用CTCAE (不良事件常用术语标准) 词典识别irAEs.
- 计算时间调整率 (TAR) 对于第一次和反复的IRAE.
主要成果:
- 总共记录了592.7个人的月的随访.
- 55%的患者 (33/60) 经历了94个irrAEs,包括巨细胞动脉炎,牛皮和无菌肺炎.
- 第一次irrAEs的TAR为每100人/年14.7,所有irrAEs的TAR为每100人/年28.4,高于意马替尼比率.
结论:
- 博苏替尼治疗与高发病率的irAEs有关.
- 这些发现支持需要更好地了解博苏替尼的安全性概况及其对免疫路径的影响.
- 这项研究强调了在接受博苏替尼治疗的CML患者中与IRAE有关的潜在安全问题.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
141
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...
