Inotuzumab ozogamicin (trade name Besponsa) is an antibody-drug conjugate for the treatment of cancers.[1] It consists of the humanized monoclonal antibody inotuzumab (for CD22), linked to a cytotoxic agent from the class of calicheamicins (which is reflected by 'ozogamicin' in the drug's name).[2]

This drug is being developed by Pfizer and UCB.

It has undergone numerous clinical trials, including two phase II trials for non-Hodgkin lymphoma (NHL). [3]

A Phase III trial in patients with relapsed or refractory CD22+ aggressive non-Hodgkin lymphoma (NHL) who were not candidates for intensive high-dose chemotherapy was terminated for futility.[4]

As of April 2016 ten clinical trials were active (including one phase III for acute lymphoblastic leukemia (ALL)[5]), six still recruiting.[3]
