About

This phase I trial is studying the side effects and best dose of SJG-136 in treating patients with relapsed or refractory acute leukemia, myelodysplastic syndromes, blastic phase chronic myelogenous leukemia, or chronic lymphocytic leukemia. Drugs used in chemotherapy, such as SJG-136, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.

Full description

OBJECTIVES:

I. Establish the maximum tolerated dose of SJG-136 in patients with relapsed or refractory acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL) myelodysplastic syndrome (MDS), chronic myelogenous leukemia in blastic phase (CML-BP), or chronic lymphocytic leukemia (CLL).

II. Determine dose-limiting toxicities and pharmacokinetics of this drug in these patients.

OUTLINE: This is a dose-escalation study.

Patients receive SJG-136 IV over 15 minutes on days 1-5. Courses repeat every 21 days in the absence of unacceptable toxicity or disease progression.

Cohorts of 3-6 patients receive escalating doses of SJG-136 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. A total of 10 patients are treated at the MTD.

Enrollment: 25 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
