TEAM-Trial: Targeting Epigenetic Therapy Resistance in AML With Bortezomib

Bortezomib is a small molecule dipeptide binding the catalytic site of the 26 S proteasome. It acts as a potent, reversible, and specific inhibitor of proteasomes and thus impairs the degradation of ubiquitinated proteins. It has demonstrated anti-neoplastic activity in myeloma and lymphoma. It is approved and widely used in multiple myeloma both for first line treatment and relapsed patients.

Gemtuzumab Ozogamicin is a monoclonal antibody directed against the myeloid surface antigen CD33. The antibody is linked to calicheamicin which serves as cytotoxic agent. For years, gemtuzumab ozogamicin has been tested in clinical AML trials. Though withdrawn from the US market in 2010, FDA approval was granted in September 2018, EU approval in April 2018 based on encouraging results from recent clinical trials using enhanced dosing schedules.
