简要总结
RATIONALE: Combinations of biological substances in DT388IL3 fusion protein may be able to carry cancer killing substances directly to the cancer cells.
PURPOSE: This phase I/II trial is studying the side effects and best dose of DT388IL3 fusion protein and to see how well it works in treating patients with acute myeloid leukemia or myelodysplastic syndromes.
详细描述
OBJECTIVES:
- Determine the maximum tolerated dose of DT_388IL3 fusion protein in patients with refractory or relapsed or poor-risk acute myeloid leukemia (AML) or high-risk myelodysplastic syndromes (MDS).
- Define the dose-limiting toxicities of this regimen in these patients.
- Measure the pharmacokinetics of this regimen in these patients.
- Measure the immune responses in patients treated with this regimen.
- Evaluate response and correlate with disease type (relapsed/refractory or poor-risk de novo AML or high-risk MDS), pretreatment marrow blast percentage, and leukemia blast interleukin-3 receptor density.
OUTLINE: This is a phase I, multicenter, dose-escalation study followed by a phase II, open-label study.
- Phase I: Patients receive DT_388IL3 IV over 15 minutes daily for 5 days in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of DT_388IL3 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

结局指标
主要结局
Overall Response Rate (CR+PR+SD): Percentage of Participants Experiencing Response
时间窗: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 2 months
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.
