Antibody-drug conjugates (ADCs) represent a major advance in the treatment of acute lymphoblastic leukemia (ALL). CD22 expression, seen in majority of patients with B-lineage ALL, is an ideal target for ADCs. Inotuzumab ozogamicin is an ADC comprised of a humanized IgG4 monoclonal antibody covalently linked to calecheamicin. Inotuzumab ozogamicin has shown promising single-agent activity in patients with ALL and in CD22 positive non-Hodgkin lymphoma. Studies exploring the combination of inotuzumab ozogamicin with chemotherapy are ongoing.

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
