Abstract

Treatment of adult acute lymphoblastic leukemia (ALL) has largely relied on cytotoxic chemotherapy agents borrowed from successful treatment regimens of pediatric ALL. However, the high cure rates seen in pediatric ALL have not been replicated in adults. In recent years, the development of monoclonal antibodies targeting cell surface antigens, such as CD19 and CD20, have significantly improved outcomes when used alone or in combination with cytotoxic chemotherapy. With these novel agents come challenges in managing adverse events, understanding mechanisms of resistance and determining their optimal place in therapy alongside conventional chemotherapy and allogeneic stem cell transplant. Herein we discuss the above challenges with the next addition to the armamentarium of antileukemic agents, inotuzumab ozogamicin, an antibody-drug conjugate against CD22.

Keywords: acute lymphoblastic leukemia; inotuzumab; monoclonal antibody; relapsed disease.
