BACKGROUND: The treatment of follicular lymphoma (FL) has previously centered on chemoimmunotherapy, which can be disadvantageous due to patient intolerance, cumulative toxicities, and disease refractoriness. Targeted therapies can produce deep responses and improve progression-free and overall survival with more tolerable adverse event profiles.
METHODS: We summarize the current literature and key clinical trials regarding targeted therapies in follicular lymphoma both in the front-line and in the relapsed-refractory setting.
RESULTS: Targeted therapies studied in FL include immune modulators, anti-CD20 antibodies, Bruton's tyrosine kinase (BTK) inhibitors, enhancers of zeste homolog 2 (EZH2) inhibitors, phosphoinositide 3-kinase (PI3K) inhibitors, and B-cell lymphoma 2 (BCL-2) inhibitors. Chimeric antigen receptor (CAR-T) therapy and bispecific T-cell engager (BiTE) therapies also show promise in monotherapy and in combination with targeted therapies. These therapies exhibit high overall response rates and substantial progression-free survival and overall survival, even in high-risk patients or patients previously refractory to chemotherapy or rituximab. Adverse events vary substantially but are generally manageable and compare favorably to the cumulative toxicities of chemotherapy.
CONCLUSION: Targeted therapies represent a paradigm shift in the treatment of FL. Further studies are needed to directly compare these targeted therapies and their combinations, as well as to investigate biomarkers predictive of response.
