RATIONALE: Drugs used in chemotherapy, such as flavopiridol, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.
PURPOSE: This phase I trial is studying the side effects and best dose of flavopiridol in treating patients with relapsed or refractory acute myeloid leukemia, acute lymphoblastic leukemia, or chronic myelogenous leukemia.
- Determine the maximum tolerated dose of flavopiridol in adult (stratum 1) and pediatric (stratum 2) patients with relapsed or refractory acute myeloid leukemia, acute lymphoblastic leukemia, or chronic myelogenous leukemia in blast crisis.
- Determine the qualitative and quantitative toxic effects of this drug, in terms of organ specificity, time course, predictability, and reversibility, in these patients.
- Determine, preliminarily, the clinical activity of this drug in these patients.
- Determine the plasma and cellular pharmacokinetics of this drug in these patients.
- Determine the pharmacodynamics of this drug in these patients.
- Correlate drug-induced apoptosis of acute leukemia cells in vitro with clinical response in patients treated with this drug.
- Correlate inflammatory cytokine levels with pharmacokinetics, pharmacodynamics, and laboratory and clinical parameters of treatment in patients treated with this drug.
OUTLINE: This is a dose-escalation study. Patients are stratified according to age group (adult [≥ 18 years] vs pediatric [1-17 years]).
Patients receive flavopiridol IV over 30 minutes followed by a 4-hour infusion on days 1-3. Treatment repeats every 21 days for up to 6 courses in the absence of unacceptable toxicity or disease progression.
Cohorts of 3-6 patients receive escalating doses of flavopiridol 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.
Patients are followed every 2 months for 1 year and then every 6 months for 4 years.
PROJECTED ACCRUAL: A total of 88 patients will be accrued for this study within 1-24 months.

This is a multicenter, open-label, study of alvocidib in previously treated chronic lymphocytic leukemia patients. Primary objective of the study is to determine overall response rate. T...
This phase I trial studies the side effects and best dose of lenalidomide when given together with alvocidib in treating patients with relapsed or refractory B-cell chronic lymphocytic leu...
The purpose of this Phase I study is to determine the safety and tolerability including the maximum dose (MTD) and dose-limiting toxicities (DLTs) of alvocidib when administered over a ran...
RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. A...
More effective treatment options for elderly acute myeloid leukemia (AML) patients are needed as only 25-50% of patients respond to standard-of-care therapies, response duration is typically short, an...
Extracellular vesicles (EV) are nano-sized membrane enclosed vehicles that are involved in cell-to-cell communication and carry cargo that is representative of the parent cell. Recent studies have hig...
Cure of acute leukemia after transplantation is mediated by the grafted cells. We investigated the graft-versus-leukemia effect (GVL) in patients with cutaneous acute graft-versus-host disease (GVHD) ...
Survival for acute lymphoblastic leukemia (ALL) decreases with age. Patients across all age groups from a homogeneous ethnic and socioeconomic background were studied to document age effect.
Acute promyelocytic leukemia (APL) is one type of acute myeloid leukemia (AML) featured by abnormal, heavily granulated promyelocytes. This study aimed to investigate the antitumor activity of icariin...
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.
