Abstract

Adoptive cell therapy (ACT) has emerged as an effective therapy for patients with metastatic melanoma. Since the first introduction of the protocol in 1988 [1], major improvements have been achieved with response rates of 40%-72% among patients who were resistant to previous treatment lines. Both cell product and conditioning regimen are major determinants of treatment efficacy; therefore, developing ACT protocols explore diverse ways to establish autologous intra-tumoral lymphocyte cultures or peripheral effector cells as well as different lymphodepleting regimens. While a proof of feasibility and a proof of concept had been established with previous published results, ACT will need to move beyond single-center experiences, to confirmatory, multi-center studies. If ACT is to move into widespread practice, it will be necessary to develop reproducible high quality cell production methods and accepted lymphodepleting regimen. Two new drugs, ipilimumab (Yervoy, Bristol-Myers Squibb) and vemurafenib (Zelboraf, Roche), were approved in 2011 for the treatment of metastatic melanoma based on positive phase III trials. Both drugs show a clear overall survival benefit, so the timing of when to use ACT will need to be carefully thought out. In contrast to these 2 new, commercially available outpatient treatments, ACT is a personally-specified product and labor-intensive therapy that demands both acquisition of high standard laboratory procedures and close clinical inpatient monitoring during treatment. It is unique among other anti-melanoma treatments, providing the potential for a durable response following a single, self-limited treatment. This perspective drives the efforts to make this protocol accessible for more patients and to explore modifications that may optimize treatment results.

摘要

过继细胞疗法(ACT)已成为转移性黑色素瘤患者的有效治疗方法。自 1988 年首次引入该方案以来,对于先前治疗线耐药的患者,其反应率已提高到 40%-72%[1]。细胞产品和调理方案都是治疗效果的主要决定因素;因此,制定 ACT 方案探索了多种方法来建立自体肿瘤内淋巴细胞培养物或外周效应细胞以及不同的淋巴耗竭方案。虽然之前发表的结果已经证明了可行性和概念验证,但 ACT 需要超越单中心经验,进行确认性、多中心研究。如果 ACT 要广泛应用于临床实践,就需要开发可重复的高质量细胞生产方法和可接受的淋巴耗竭方案。两种新药,伊匹单抗(Yervoy,百时美施贵宝)和威罗非尼(Zelboraf,罗氏),于 2011 年基于阳性 III 期试验被批准用于治疗转移性黑色素瘤。这两种药物均显示出明确的总生存获益,因此需要仔细考虑何时使用 ACT。与这两种新的、可商业化的门诊治疗方法不同,ACT 是一种个性化的产品,需要劳动密集型治疗,既需要获得高标准的实验室程序,又需要在治疗期间进行密切的临床住院监测。它在其他抗黑色素瘤治疗方法中是独一无二的,提供了单次自限性治疗后持久反应的潜力。这种观点推动了使更多患者能够获得该方案并探索可能优化治疗效果的修改的努力。
