概括
这一第一阶段试验表明CT071,一种针对GPRC5D的新型仿真抗原受体 (CAR) T细胞疗法,对复发性或耐火性多发性骨髓瘤安全有效,达到100%的客观应答率.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 细胞疗法 细胞疗法
背景情况:
- 复发性或耐药性多发性骨髓瘤 (MM) 存在重大未满足的医疗需求,因为目前的治疗方法提供有限的治疗选择.
- 化学抗原受体 (CAR) T细胞疗法代表了治疗血液性恶性瘤的有希望的途径.
- G蛋白结合受体类C组5成员D (GPRC5D) 是多发性骨髓瘤治疗的新兴标.
研究的目的:
- 评估CT071的初步安全性,活性和细胞动力学,一种新的GPRC5D导向的CAR T细胞疗法.
- 确定CT071在复发性或耐火性多发性髓瘤患者的推第二期剂量.
主要方法:
- 一个单中心,单臂,一期临床试验在中国进行.
- 20名患有复发性或耐火性多发性髓瘤的患者在0.1 × 10^6或0.3 × 10^6 CAR T 细胞/kg的剂量下接受了CT071.
- 安全终点包括剂量限制性毒性和不良事件;活动被评估为次要终点.

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.

Tumor Immunotherapy
1.7K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
