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 MG98 in treating patients who have
advanced solid tumors.
- Determine the maximum tolerated dose of MG98 in patients with advanced solid tumors.
- Assess the safety, toxicity, and pharmacokinetics of this treatment regimen in this
- Evaluate the effectiveness of this treatment regimen in these patients.
OUTLINE: This is a dose escalation, multicenter study.
Patients receive MG98 IV over 2 hours twice weekly for 3 weeks. Courses are repeated every 4
weeks. Treatment continues in the absence of disease progression or unacceptable toxicity.
The dose of MG98 is escalated in cohorts of 1-6 patients 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 at week 4, then at least every 3 months until relapse of disease.
