Primary Outcome Measures:
  • Maximum-tolerated dose (MTD) based on the incidence of dose-limiting toxicity (DLT) as assessed by Common Toxicity Criteria (CTC) version 2.0 [ Time Frame: 28 days ] [ Designated as safety issue: Yes ]
    Presented primarily in a descriptive fashion.

  • Number of toxicity incidents as assessed by CTC version 2.0 [ Time Frame: Up to 3 months after completion of treatment ] [ Designated as safety issue: Yes ]
    Frequency distributions and other descriptive measures will form the basis of the analysis of these variables.

Secondary Outcome Measures:
  • Biologic activity rate (BAR) [ Time Frame: At day 1 and at day 28 ] [ Designated as safety issue: No ]
    A rate will be calculated by dividing the number of patients with BA by the number of patients treated at the phase II recommended dose level.

  • Angiogenesis inhibition via an ex vivo angiogenesis assay [ Time Frame: At day 1 and at day 28 ] [ Designated as safety issue: No ]
    The relationship between each marker and dose level will be explored descriptively.

  • Number of responses [ Time Frame: Up to 3 months after completion of treatment ] [ Designated as safety issue: No ]
    Responses will be summarized by simple descriptive summary statistics delineating complete and partial responses as well as stable and progressive disease.

Detailed Description:


I. Determine the optimal biologic dose and/or maximum tolerated dose of 2-methoxyestradiol in patients with advanced solid tumors.

II. Determine the qualitative and quantitative toxic effects of this drug in these patients.

III. Determine the pharmacokinetics and metabolism of this drug in these patients.

IV. Determine the biologic changes within the tumor of these patients when treated with this drug.

V. Correlate the pharmacokinetics and toxicity of this drug in these patients. VI. Evaluate the biologic evidence of angiogenesis inhibition in patients receiving this drug.

VII. Correlate genetic polymorphisms in cytochrome P450 and sulfotransferases isoforms with the pharmacokinetics of this drug.

OUTLINE: This is a dose-escalation study.

Patients receive oral 2-methoxyestradiol (2-ME) once daily. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of 2-ME until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Additional patients are treated at the MTD.

Patients are followed for 3 months.

PROJECTED ACCRUAL: A total of 42-60 patients will be accrued for this study within 19 months.
