OUTLINE: This is a dose escalation study. Patients receive oral LY293111 twice daily. Treatment continues for a maximum of 6 months in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of LY293111 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 6 patients experience dose limiting toxicity. Additional patients are treated at the MTD. Patients are followed at 30 days.
