Study summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase I trial to study the effectiveness of benzoylphenylurea in treating patients who have advanced solid tumors.

Read the detailed description

OBJECTIVES:

  • Determine the maximum tolerated dose of benzoylphenylurea in patients with advanced solid tumors.
  • Evaluate the acute and chronic toxicity profile of this regimen in these patients.
  • Evaluate the pharmacokinetics and metabolites of this regimen and any potential correlation with pharmacodynamic effects in these patients.
  • Determine the antitumor activity of this regimen in these patients.

OUTLINE: This is a dose-escalation study.

Patients receive oral benzoylphenylurea (BPU) once weekly. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of BPU 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 a dose-limiting toxicity. Once the MTD is determined, 12 additional patients are accrued and treated with BPU as above to confirm the MTD.

Patients are followed for 30 days.

PROJECTED ACCRUAL: Approximately 18-24 patients will be accrued for this study.

What researchers measure

Primary outcomes

  1. Determine Maximum Tolerated Dose of BPU

    Toxicity was assessed weekly during the first 2 cycles, and monthly thereafter, using the National Cancer Institute Common Toxicity Criteria (NCI CTCv2). Dose limiting toxicity (DLT) was defined as dose delays \>2 weeks, grade 4 haematologic toxicity (except grade 4 neutropenia lasting \<5 days), or grade 3 nonhaematologic toxicity. The maximum tolerated dose (MTD) is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience a dose-limiting toxicity.

    Time frame: 4 weeks (1 course of treatment for each subject)

Secondary outcomes

  1. Number of Patients With Adverse Events

    Time frame: every 4 weeks

  2. Area Under the Plasma Concentration Versus Time Curve (AUC) of BPU

    Time frame: 8 weeks

  3. Test for Antitumor Activity in Blood and Tissue

    Time frame: baseline
