概括
固定持续时间的皮尔托布鲁丁尼加维尼托克拉克斯 (PV) 或PVR在复发性或耐药性慢性淋巴细胞白血病 (CLL) 中显示出高响应率和不可检测的最小残留疾病. 这种组合疗法被很好地容忍,即使在以前接受了共价布鲁顿氨酸激酶抑制剂 (BTKi) 治疗的患者中也是如此.
科学领域:
- 在瘤学瘤学.
- 血液学 血液学 血液学
- 药理学 药理学是指药理学的学科.
背景情况:
- 慢性淋巴细胞白血病 (CLL) 是一种常见的B细胞恶性瘤.
- 复发性或耐药性 (R/R) CLL 存在治疗挑战,特别是在之前的治疗后.
- 布鲁顿氨酸激酶抑制剂 (BTKi) 是有效的,但可能会发生耐药性和不耐受性.
研究的目的:
- 为了评估固定时间的皮尔托布鲁丁尼布加维尼托克拉克斯 (PV) 或皮尔托布鲁丁尼布加维尼托克拉克斯和修复剂 (PVR) 在R/R CLL.患者的疗效和安全性.
- 评估R/RCLL患者的结局,包括那些先前有共价BTKi暴露的患者.
- 为了确定不可检测的最小残留疾病 (uMRD) 和无进展生存率 (PFS) 的率.
主要方法:
- 一个1b期临床试验,涉及患有R/R CLL的患者.
- 患者接受了25个周期的固定时间PV (n=15) 或PVR (n=10).
- 允许先前的共价BTKi治疗,但不允许先前的venetoclax.
主要成果:
- 总体响应率为PV的93.3%,PVR的100%.
- 在12个循环后,85.7%的PV和90.0%的PVR患者在周围血液中实现了UMRD (<10-4).
- 18个月的PFS为PV的92.9%和PVR的80.0%;常见的≥3级不良事件包括中性质减退 (52%) 和贫血 (16%).
结论:
- 固定时间PV或PVR在R/RCLL患者中显示出有前途的疗效和耐受性.
- 组合疗法即使在患者有先前的共价BTKi暴露的情况下也有效.
- 基于皮尔托布鲁丁尼布的疗法代表了R/R CLL的潜在新治疗选择.

Treatment Resistant Cancers
2.6K
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
8.5K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

Clinical Trials: Overview
4.7K
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...
