There is a critical need for new therapeutic approaches to treat advanced stage rectal cancer, which has increased incidence in younger people and poor prognosis. Working with a multidisciplinary team, Dr. Aguilera is leading a randomized clinical trial that combines an anti-CD40 agonist immunotherapy with radiation and chemotherapy for locally advanced rectal cancer. The drug aims to activate the protein CD40 on dendritic cells which plays a critical role in generating T-cell immunity. As part of the study, Dr. Aguilera is investigating the factors that influence a patient's immune response to this combination treatment with the goal of optimizing therapy for difficult gastrointestinal cancers. If the proposed treatment is successful, it could become a new therapeutic standard that lowers the risk of metastasis, improves survival, shortens the treatment course and potentially avoids the need for surgery.
