## TL;DR

An antibody-drug conjugate put four in five relapsed ALL patients into remission versus fewer than one in three with chemotherapy.

## Summary

INO-VATE ALL, trial NCT01564784 sponsored by Pfizer and published in the New England Journal of Medicine in 2016, showed that the CD22 antibody-drug conjugate inotuzumab ozogamicin put four in five adults with relapsed or refractory B-cell acute lymphoblastic leukaemia into remission versus fewer than one in three with intensive chemotherapy. It randomised 326 patients, met its primary remission endpoint with far higher MRD negativity and four times as many patients proceeding to transplant, while overall survival was not significantly different at the prespecified boundary, and hepatic veno-occlusive disease occurred in about a tenth. Whether lower frontline doses avoid the liver toxicity is the open question.
