Mylotarg (gemtuzumab ozogamicin)

P1, N=26, Completed, Baylor College of Medicine | Active, not recruiting --> Completed

This review compared the efficacy and safety of low-dose cytarabine (LDAC), azacitidine (AZA), 5- and 10-day decitabine (DEC), and gemtuzumab ozogamicin, alone or combined with drugs such as venetoclax (VEN), in older adults with AML ineligible for conventional chemotherapy. Treatment decisions should consider patient goals and functional status. These findings informed eight recommendations in updated ASH-AML guidelines.

These results support further evaluation of combination therapies with corresponding small-molecule inhibitors (currently pursued for therapy of other cancers) toward clinical testing as novel strategies to increase the efficacy of CLM-based ADCs such as GO and InO.

Twenty-five years ago, the FDA gave the first approval to an antibody-drug conjugate (ADC), the CD33-targeting gemtuzumab ozogamicin for acute myeloid leukemia. As the drug faced setbacks and redemption-it was withdrawn in 2010 following poor phase III trial results but reapproved in 2017 at a lower dose-a surge of pharmaceutical interest in ADCs has yielded newly approved agents and new strategies for developing them.

Our results show that GO can safely be combined with intensive chemotherapy with midostaurin in ND, FLT3-mutated AML. This trial was registered at www.clinicaltrials.gov as #NCT03900949.

Blinatumomab and inotuzumab ozogamicin have become established treatments, enhancing remission rates, measurable residual disease clearance, and overall survival in relapsed/refractory disease, and these agents, are now increasingly incorporated into frontline therapy...In acute myeloid leukemia (AML), gemtuzumab ozogamicin has shown significant clinical benefits, particularly in molecularly defined subsets...This review highlights how immunotherapy has reshaped treatment paradigms across acute leukemias, underscoring successful experiences in B-ALL. These insights emphasize the need for continued innovation to overcome existing hurdles in AML and T-ALL, ultimately aiming to enhance patient outcomes and quality of life.
