6-Hydroxymethylacylfulvene in Treating Patients With Refractory Myelodysplastic Syndrome, Acute Myeloid Leukemia, Acute Lymphocytic Leukemia, or Blastic Phase Chronic Myelogenous Leukemia

Phase I Study of MGI-114 (NSC#683863) in Patients With Refractory Myelodysplastic Syndromes, Acute Leukemia and Chronic Myelogenous Leukemia in Blastic Phase (CML-BP)

Phase I trial to study the effectiveness of 6-hydroxymethylacylfulvene in treating patients who have refractory myelodysplastic syndrome, acute myeloid leukemia, acute lymphocytic leukemia, or blastic phase chronic myelogenous leukemia. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die.

OBJECTIVES:

I. Determine the maximum tolerated dose for 6-hydroxymethylacylfulvene in patients with refractory myelodysplastic syndrome, acute myeloid leukemia, acute lymphocytic leukemia, or blastic phase chronic myelogenous leukemia.

II. Determine the qualitative and quantitative toxicities of this treatment in these patients.

III. Determine the duration and reversibility of the qualitative and quantitative toxicities of this treatment in these patients.

IV. Evaluate, in a preliminary manner, the antileukemic activity of this treatment in these patients.

V. Assess relative mRNA levels of selected NER genes (ERCC1, ERCC2, and ERCC3) in tumor tissues of patients treated with this regimen and correlate with clinical outcome.

OUTLINE: This is a dose escalation study.

Patients receive 6-hydroxymethylacylfulvene (HMAF) IV over 5 minutes on days 1-5. Treatment repeats every 3-4 weeks for at least 2 courses in the absence of disease progression or unacceptable toxicity. Cohorts of 3 patients receive escalating doses of HMAF. The maximum tolerated dose is defined as the dose at which dose limiting toxicity occurs in at least 40% of patients.

Patients are followed every 3 months for 1 year and then every 6 months thereafter.

DISEASE CHARACTERISTICS:

• Diagnosis of refractory myelodysplastic syndrome (MDS), acute myeloid leukemia (AML), acute lymphocytic leukemia, or blastic phase chronic myelogenous leukemia MDS and AML include:

  • First salvage with primary refractory disease or first complete remission of no more than 12 months
  • Second or greater salvage

• After the maximum tolerated dose is determined, AML patients with an intermediate prognosis (i.e., complete remission of more than 12 months, but less than 24 months) are eligible

• No candidates for curative therapies such as allogeneic bone marrow transplantation

• No uncontrolled angina
• No myocardial infarction within past 6 months
• No concurrent grade 4 infection
• Not pregnant or nursing
• Negative pregnancy test
• Fertile patients must use effective contraception

• Concurrent hydroxyurea allowed if needed to control blast counts
• No concurrent systemic anticancer chemotherapy
• At least 2 weeks since prior endocrine therapy and recovered
• Concurrent corticosteroids allowed if needed to control blast counts
