Inotuzumab in Older Patients with Newly Diagnosed Acute Lymphoblastic Leukemia—A Podcast

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.
