OUTLINE: This is a dose escalation study. Patients receive TG4010 IM weekly for 4 weeks, every other week for 8 weeks, and then every 4 weeks. Treatment continues every 4 weeks in the absence of unacceptable toxicity or disease progression. Cohorts of 3-6 patients receive escalating doses of TG4010 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 3 of 6 patients experience treatment related grade 3 toxicity. If any patient experiences grade 4 toxicity, the prior dose level is considered the MTD.
