A Phase I/II Study of Intratumoral Injection of SD-101, an Immunostimulatory CpG, and Intratumoral Injection of Ipilimumab, an Anti-CTLA4 Monoclonal Antibody, in Combination With Local Radiation in Low-Grade B-Cell Lymphomas

This phase I/II trial studies the side effects and best dose of ipilimumab in combination with toll-like receptor 9 (TLR9) agonist SD-101 and radiation therapy in treating patients with low-grade B-cell lymphoma that has returned. Monoclonal antibodies, such as ipilimumab, may block cancer growth in different ways by targeting certain cells. Biological therapies, such as TLR9 agonist SD-101, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. Giving ipilimumab in combination with TLR9 agonist SD-101 and radiation therapy may be a better treatment for B-cell lymphoma.
