PV-10 Chemoablation of Recurrent Breast Carcinoma

This is a single center, open label, ascending dose study. Subjects with at least one recurrent, histologically confirmed measurable soft tissue breast carcinoma who are candidates for lumpectomy (removal of the lesion from the site of recurrence in the breast or at another site) or mastectomy will receive a single intralesional injection of PV-10 into a single target lesion to uniformly infiltrate the target lesion and up to a 0.5 cm margin at a dose of up to 1.0 mL/cc lesion volume. Systemic and locoregional adverse events will be monitored over the study interval. Subject accrual and PV-10 administration will be stopped if more than 1 subject has a treatment related Grade 3 non-hematological or Grade 4 hematological toxicity within a period of two weeks after PV-10 administration.
