Abstract PS16-03: Intratumoral dosing of INT230-6 in Early-Stage Breast Cancer Patients Induces Tumor Cell Necrosis and Immunomodulatory Effects: A Phase II Randomized Window-Of-Opportunity Study – the INVINCIBLE Trial

Abstract Background: Larger tumors pose an increased risk for breast cancer (BC) recurrence post-surgery. In addition, most BC outside of the triple negative subtype are considered immunological quiescent and minimally responsive to immunotherapies. One potential method to combat disease recurrence risk and induce immune activation pre-surgery is through a local therapy that could cause cell death to expose tumor antigens, provide adjuvants for …
