Older patients with acute lymphoblastic leukemia (ALL) have historically had poor outcomes (5-year survival rate, 20%) with standard intensive and dose-adjusted chemotherapy regimens, due to a high incidence of adverse biologic features including high-risk cytogenetics, presence of TP53 mutations, and poor tolerance to intensive therapy. Thus, there is an unmet medical need in this patient population. Inotuzumab ozogamicin is a humanized antibody-drug conjugate that targets CD22-positive leukemic blasts. It is approved for the treatment of relapsed or refractory ALL and has been shown to be effective and tolerable in older patients. Several ongoing trials in older patients with newly diagnosed ALL have yielded encouraging data with inotuzumab ozogamicin in induction alone and in combination with low-intensity chemotherapy. In this podcast, the authors summarize and highlight some of the recent findings on the use of inotuzumab ozogamicin as induction therapy for older adults with newly diagnosed ALL.
患有急性淋巴细胞白血病(ALL)的老年患者由于存在高风险的细胞遗传学、TP53 突变的存在以及对强化治疗的耐受性差等不良生物学特征,其接受标准强化和剂量调整化疗方案的预后较差(5 年生存率为 20%)。因此,这一患者群体存在未满足的医疗需求。Inotuzumab ozogamicin 是一种针对 CD22 阳性白血病细胞的人源化抗体药物偶联物。它被批准用于治疗复发或难治性 ALL,并且在老年患者中已被证明是有效且耐受的。几项针对新诊断为 ALL 的老年患者的正在进行的试验显示,Inotuzumab ozogamicin 单独使用和与低强度化疗联合使用在诱导缓解方面均获得了令人鼓舞的数据。在本期播客中,作者总结并强调了一些关于 Inotuzumab ozogamicin 作为新诊断为 ALL 的老年患者诱导治疗的最新研究结果。
