概括
在共价布鲁顿氨酸激酶抑制剂 (cBTKis) 治疗后,复发/耐药的上衣细胞淋巴瘤 (R/R MCL) 的老年患者的结局表明存活率差,医疗利用率高. 这凸显了在R/R MCL治疗中对新型治疗方法的未满足需求.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 协同布鲁顿的氨酸激酶抑制剂 (cBTKis) 是复发性/耐火性地幔细胞淋巴瘤 (R/R MCL) 的标准.
- 有限的现实世界数据存在于R/R MCL中cBTKi治疗后的临床和经济结果.
- 患者耐药性和不良事件需要了解cBTKi治疗后的结果.
研究的目的:
- 评估在第三线 (3L) 治疗后患有R/R MCL的老年患者的实际临床和经济结果,包括之前使用CBTKi的老年患者.
- 为了评估治疗模式,医疗资源利用率 (HRU),成本和整体存活率 (OS) 3L启动后.
主要方法:
- 美国医疗保险索赔 (2010-2019) 的回顾性分析.
- 确定了新诊断的MCL的老年患者 (≥66岁),接受3L治疗和之前的cBTKi暴露.
- 评估结果在3L启动后≥12个月,包括HRU,成本和OS.
主要成果:
- 分析了230名先前使用cBTKi的老年R/R MCL患者 (平均年龄75.0).
- 常见的3L治疗包括化疗,列纳利多米德和博特佐米布;25.7%接受了随后的cBTKi (伊布鲁丁尼布或阿卡拉布鲁丁尼布).
- 平均生存期为9.4个月,一年生存率为43.7%. 在3L启动后观察到高HRU (73.6%住院) 和成本 (145,726美元).
结论:
- 对于老年R/R MCL患者在cBTKi治疗后的有效治疗方法存在重大未满足的需求.
- 低生存率和高医疗负担强调需要新的治疗策略.
- 持续开发新型疗法对于改善这种患者群体的治疗结果至关重要.

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers
155
Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

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.
