Intratumoral Injection of an Immunostimulatory CpG, SD-101, Combined With Local Radiation for the Treatment of Recurrent or Progressive Lymphoma After Allogeneic Hematopoietic Cell Transplantation
For patients with lymphoma that recurs after chemotherapy, bone marrow transplantation using cells from a healthy donor represents potentially curative treatment. In these individuals, cure is possible because transplantation of healthy donor immune cells can fight the lymphoma in the patient. The goal of this work is to test a strategy that activates the healthy donor immune cells so that they more effectively fight lymphoma and can result in anincreased cure rate for these patients. Our group has previously studied CpG, an immune activating medication, in patients with lymphoma and demonstrated modest anti-tumor responses. We now have a more potent form of CpG which we intend to test to see if it will better activate the donor immune cells and result in shrinkage of tumor throughout the entire body, not just at the injected site.
