Trial Outcomes & Findings for DT388IL3 Fusion Protein in Treating Patients With Acute Myeloid Leukemia or Myelodysplastic Syndromes (NCT NCT00397579)

NCT ID: NCT00397579

Last Updated: 2019-04-23

Results Overview

Patients will be treated with a maximum of five doses of approximately 15min IV infusions of DT388IL3/SL-401 over a ten day period at a maximum of once daily. Response to Treatment will be evaluated as follows: Complete response (CR): patient has a normal whole blood count; platelets with absent blasts in peripheral blood or marrow; no evidence of nodal involvement or liver/spleen involvement; no skin lesion involvement. Partial Response (PR); patient experiences a decrease of 50% or more in marrow blasts and skin lesions; and there is a decrease in the size of the nodes/liver/spleen. Stable Disease (SD); failure to achieve at least PR, and there is no evidence of progression for 2 months. Failure: death during treatment or disease progression characterized by an increase in the percentage bone marrow blast or an increase in skin or node/liver or spleen size. Reported is the percentage of participants experiencing either CR, PR or SD.
