NCT03904251

Brief Summary

This phase Ib trial studies the best dose of gemtuzumab ozogamicin when given together with CPX-351 in treating patients with acute myeloid leukemia that has come back after it was previously in remission. CPX-351 is a chemotherapy, which works in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Gemtuzumab ozogamicin is a monoclonal antibody, called gemtuzumab, linked to chemotherapy called calicheamicin. Gemtuzumab attaches to CD33 (transmembrane receptor) positive cancer cells in a targeted way and delivers ozogamicin to kill them. Giving CPX-351 and gemtuzumab ozogamicin may work better in treating patients with acute myeloid leukemia, compared to giving only one of these therapies alone.

Study Arms (1)

Treatment (CPX-351, gemtuzumab ozogamicin)

EXPERIMENTAL

INDUCTION: Patients receive liposome-encapsulated daunorubicin 44mg/m2 - cytarabine 100mg/m2 IV over 90 minutes on days 1, 3, and 5, and gemtuzumab ozogamicin 3 mg/m2 (max 4.5 mg) IV over 120 minutes on day 7, or days 4 and 7, or days 1, 4, and 7 in the absence of disease progression or unacceptable toxicity. CONSOLIDATION: Patients who achieve CR/CRi receive consolidation therapy at the discretion of the treating physician and/or proceed to allogeneic HSCT.
