Brief 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 XK469 in treating patients who have advanced solid tumors.

Condition or disease Intervention/treatment Phase
Unspecified Adult Solid Tumor, Protocol Specific Drug: R(+)XK469 Phase 1

Detailed Description:


  • Determine the maximum tolerated dose, dose-limiting toxicity, and recommended phase II dose of XK469 in patients with advanced solid tumors.
  • Determine the safety of this drug in these patients.
  • Determine the pharmacokinetics of this drug in these patients.
  • Determine, preliminarily, any anti-tumor activity of this drug in these patients.
  • Determine the drug metabolism, drug interaction potential, molecular and cellular predictors of efficacy and toxicity, and clinical confirmation of molecular responses in patients treated with this drug.

OUTLINE: This is a dose-escalation study.

Patients receive XK469 IV over 20 minutes on days 1-5. Treatment repeats every 21 days for at least 2 courses in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of XK469 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of the first 6 patients experience dose-limiting toxicity.

Once the MTD is determined, up to 15 patients are treated at that dose. Patients in the expanded MTD cohort also receive oral NovaSoy® soybean extract twice daily for the study duration.

Patients are followed every 4 weeks.

PROJECTED ACCRUAL: Approximately 25-40 patients will be accrued for this study within 12-15 months.
