Abstract
Follicular lymphoma (FL) is the most common type of indolent lymphoma in the Western world, accounting for approximately 30% of lymphoma cases. FL is known for its recurrent nature, necessitating diverse treatment options. The introduction of rituximab, an anti-CD20 antibody, has greatly improved FL outcomes and paved the way for targeted therapies. In this review, we thoroughly explore the structure, mechanism of action, clinical outcomes, and side effects of currently approved monoclonal antibodies (mAb) for FL. Furthermore, we provide insights into ongoing clinical trials and emerging monoclonal antibodies that hold promise for the future of FL treatment. A comprehensive literature search was conducted using various medical databases, including ASH and ASCO publications, as well as PubMed. The clinicaltrials.gov website was used to compile a list of investigational monoclonal antibodies from ongoing clinical trials. The future of antibody-based therapy for follicular lymphoma shows great promise, with a focus on enhancing antibody efficacy, prioritizing optimized combination therapies to address treatment resistance, and evaluating bispecific antibodies as first-line therapies, all while carefully balancing risks and benefits and sequencing treatments appropriately for better disease management. These directions have the potential to establish antibodies as a central component of follicular lymphoma treatment.
