概括
在SCART试验中,研究了塞卢美替尼布与卡波西肉瘤的抗逆转录病毒疗法. 推剂量显示出有限的疗效和毒性问题,需要进一步研究其他药物.
科学领域:
- 在瘤学瘤学.
- 传染性疾病 传染性疾病
- 药理学 药理学是指药理学的学科.
背景情况:
- 卡波西肉瘤 (KS) 是最常见的与艾滋病毒相关的恶性瘤,由卡波西肉瘤疹病毒 (KSHV) 和MAPK通路激活驱动.
- 抗逆转录病毒疗法 (ART) 已经减少了KS的发病率,但对进展性疾病的有效治疗仍然至关重要.
- 塞卢梅提尼布是一种MEK抑制剂,向涉及KS病变的MAPK途径.
研究的目的:
- 为了确定安全和推的二期剂量 (RP2D) 结合塞卢梅替尼与ART治疗艾滋病毒相关的KS.
- 评估塞卢美替尼布加ART在进展性KS患者中的疗效.
- 评估组合治疗的安全性,耐受性和药理动力学.
主要方法:
- 一个前性的,单臂的,开放的,多中心的I/II期试验 (SCART) 在英国四个中心进行.
- 符合条件的患者有艾滋病毒,正在接受ART治疗,病毒载量受抑制,并确认进展的KS.
- 第一阶段专注于剂量限制性毒性 (DLT),以确定RP2D;第二阶段评估了客观反应 (OR) 率.
主要成果:
- 一个DLT发生在75毫克每天两次 (bd),确定这是RP2D.
- 在RP2D治疗的12名患者中,观察到一个部分反应 (8.3%).
- 不良事件包括一个DLT,两个严重的不良反应和非严重的毒性;ART水平和HIV病毒载量没有受到影响,CD4计数有所改善.
结论:
- 由于招募速度缓慢和患者对毒性的担忧,SCART试验被提前关闭.
- 由于有效性和毒性有限,不建议在与艾滋病毒相关的KS中将75毫克Selumetinib与ART联合使用.
- 需要对塞卢梅提尼布与抗血管原剂或免疫检查点抑制剂进行进一步的研究.

Retrovirus Life Cycles
45.5K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Combination Therapies and Personalized Medicine
4.8K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

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.
