Determine the complete pathologic complete response (pCR) rate in patients with locally advanced rectal adenocarcinoma.


Clinical Trial Description

A phase II randomized trial 3:2 with short course radiotherapy followed by mFOLFOX chemotherapy prior to trans abdominal resection with or without an antiCD40 agonist antibody (APX005M). There will be continuous safety assessment for at least 6 patients. Planned accrual of 58 patients. An interim analysis after 30 patients have completed treatment and there will be early stopping criteria for futility or efficacy. Short course radiotherapy will consist of 5Gy x 5 to the pelvis and patients on APX005M arm will receive one infusion during radiotherapy course, have a two week break, then start FOLFOX with APX005M in conjunction with five out of six cycles of chemotherapy.
