RATIONALE: Drugs used in chemotherapy, such as rebeccamycin analog, work in different ways to stop cancer cells from dividing so they stop growing or die.
PURPOSE: This phase I trial is studying the side effects and best dose of rebeccamycin analog in treating patients with relapsed or refractory acute myeloid leukemia, myelodysplastic syndrome, acute lymphoblastic leukemia, or chronic myelogenous leukemia in blast phase.
- Determine the maximum tolerated dose and dose-limiting toxicity of rebeccamycin analogue (XL119) in patients with relapsed or refractory acute myeloid leukemia, myelodysplastic syndromes, acute lymphoblastic leukemia, or chronic myelogenous leukemia in blastic phase.
OUTLINE: This is a dose-escalation study.
Patients receive rebeccamycin analogue (XL119) IV over 1 hour on days 1-5. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients achieving a complete response (CR) receive 1 additional course beyond CR. Patients achieving a partial response (PR) or hematologic improvement (HI) receive 2 additional courses beyond PR or HI.
Cohorts of 3-6 patients receive escalating doses of XL119 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.
PROJECTED ACCRUAL: Approximately 3-40 patients will be accrued for this study.

To report on a case of therapy-related acute monocytic leukemia(t-AML) with t(11;17) (q23;q21)/MLL-AF17q after successful treatment for acute promyelocytic leukemia(APL) with t(15;17) (q22;q21)/PML-RA...
Leukemia cutis is uncommon in patients with acute lymphoblastic leukemia. It typically presents with dermal papules or subcutaneous nodules, with no epidermal or upper papillary dermal involvement on ...
Measurable residual disease (MRD) has prognostic importance for patients with acute myeloid leukemia (AML). How leukemia providers incorporate MRD into routine practice remains undefined.
Acute lymphoblastic leukemia (ALL) in adults is an invariably aggressive and rare disease. Its treatment is based on the use of multidrug regimens, which have been improved since the 1970s. Few publis...
A replication-defective strain of Murine leukemia virus (LEUKEMIA VIRUS, MURINE) capable of transforming lymphoid cells and producing a rapidly progressing lymphoid leukemia after superinfection with FRIEND MURINE LEUKEMIA VIRUS; MOLONEY MURINE LEUKEMIA VIRUS; or RAUSCHER VIRUS.
A strain of Murine leukemia virus (LEUKEMIA VIRUS, MURINE) producing leukemia of the reticulum-cell type with massive infiltration of liver, spleen, and bone marrow. It infects DBA/2 and Swiss mice.
A strain of Murine leukemia virus (LEUKEMIA VIRUS, MURINE) arising during the propagation of S37 mouse sarcoma, and causing lymphoid leukemia in mice. It also infects rats and newborn hamsters. It is apparently transmitted to embryos in utero and to newborns through mother's milk.
A chronic leukemia characterized by a large number of circulating prolymphocytes. It can arise spontaneously or as a consequence of transformation of CHRONIC LYMPHOCYTIC LEUKEMIA.
A lymphoid leukemia characterized by a profound LYMPHOCYTOSIS with or without LYMPHADENOPATHY, hepatosplenomegaly, frequently rapid progression, and short survival. It was formerly called T-cell chronic lymphocytic leukemia.
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
Leukemia is a type of cancer of the blood or bone marrow characterized by an abnormal increase of immature white blood cells called "blasts". Leukemia is a broad term covering a spectrum of diseases. In turn, it is part of the even broader grou...
