Summary

"This trial is testing a new combination treatment for patients with high-risk leukemia and myelodysplastic syndrome before they undergo a stem cell transplant. The treatment includes a medication called daratumumab

Who is the study for?

This trial is for patients with high-risk acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), or myelodysplastic syndrome (MDS) who are candidates for donor stem cell transplant. Specific eligibility criteria were not provided, but typically include factors like age, overall health status, and the specifics of their cancer diagnosis.

What is being tested?

The trial tests a new treatment combining 225Ac-DOTA-Anti-CD38 daratumumab monoclonal antibody with chemotherapy drugs fludarabine and melphalan, plus total marrow and lymphoid irradiation (TMLI). It aims to find the safest dose that's also effective as pre-transplant conditioning in high-risk AML, ALL, and MDS patients.

What are the potential side effects?

Potential side effects may include reactions to the monoclonal antibody such as infusion-related symptoms; damage to organs from radiation; side effects from chemotherapy like nausea, fatigue, hair loss; increased risk of infections due to immune system suppression.

Experimental Treatment

Group I: Treatment ( Actinium Ac 225-DOTA-Daratumumab)Experimental Treatment17 Interventions

Patients receive daratumumab IV over 45 minutes followed by indium In 111-DOTA-daratumumab IV over 15 minutes and actinium Ac 225-DOTA-daratumumab IV over \~20-40 minutes on day -15. Patients receive TMLI BID on days -8 to -5, fludarabine IV on days -4 to -2 and melphalan IV on day -2, followed by HCT on day 0. Patients receive GVHD prophylaxis with sirolimus and tacrolimus starting on day -1. Patients also undergo CT during screening, nuclear scan and SPECT scans on study, bone marrow biopsy and aspiration, echocardiography, or MUGA, and blood sample collection during screening and throughout study.
