Safety and Efficacy Study Using Rexin-G for Breast Cancer

"Three patients will receive Rexin-G at Dose Level I. If 1 of 3 patients at Dose Level I develops a grade 3 or 4 adverse event (CTCAE Version 3.0) which appears to be related or possibly related to Rexin-G, then 3 additional patients will be enrolled at the same dose level. If at least 2 of the first 3, or 3 of 6 patients at Dose Level I develop a grade 3 to 4 adverse event which appears to be related or possibly related to Rexin-G, accrual into the study will be held.~At any dose level, up to six patients may be enrolled if there is evidence of biological activity in the first three patients. Dose escalation may stop if there is impressive evidence of biological activity. An amendment would be submitted to allow further expansion of dose level based on impressive biological activity."
