Abstract 4082: Preclinical assessment of external or targeted radiotherapy in combination with immunotherapies and co-development of companion imaging diagnostic

Abstract Immunotherapies have proven to be highly efficient for cancer treatments and combination with either internal vectorized or external radiotherapies can enhance this efficacy through notably increasing tumor immune infiltrate. The clinical evaluation of such combination therapies requires expertise and exquisite processes in multiple fields, immunotherapy, radiotherapy and nuclear medicine. Similarly, this applies into preclinical settings for assessing proof of concept of novel combinations. Herein, we will present our preclinical evaluation process to combine external or internal (i.e. lutetium-177 radiolabeled molecule) radiotherapy with immunotherapies that include radiochemistr…
