Emerging new cell therapies/immune therapies in B-cell non-Hodgkin's lymphoma.

Non-Hodgkin's lymphomas (NHL) are a heterogeneous group of lymphoproliferative disorders originating in B-lymphocytes, T-lymphocytes, or natural killer (NK) lymphocytes. First line therapy is well established and generally a combination of steroids and chemotherapy. Treatment of relapsed/refractory (R/R) NHL however remains a challenge with rapidly evolving new therapies. Many of these new therapies focus on manipulating the body's natural immune mechanisms to identify and eradicate tumor cells. There has been much success with using checkpoint inhibitors in Hodgkin's Lymphoma (HL). However, results have been modest in NHL, prompting further studies of immunomodulatory strategies to target NHL. In this article, we review the emerging immune and cell therapies for R/R B-NHL including checkpoint inhibitors, bispecific antibodies, chimeric antigen receptor (CAR) T-cell therapy, and small molecule inhibitors both alone and in combination.
