Mosunetuzumab for relapsed or refractory follicular lymphoma: a case study

Abstract

Recent advances in the diagnosis and understanding of follicular lymphoma (FL) pathogenesis have had a significant impact on therapeutic tactics. The life expectancy of patients has increased significantly. Currently, the 5-year overall survival of FL patients achieved 90 %, and its median is approaching 20 years. However, FL remains an incurable disease with periods of remission and relapse, requiring multiple therapy courses throughout the patient’s life.The main problem is the treatment of patients with refractory/relapsed forms, especially after 3rd line of therapy, as well as with a primarily resistant course and early (in the first 2 years) relapses. Therefore, despite the indolent FL course in most patients, there remains a need for new drugs that can ensure increased treatment efficacy with minimal toxicity and simultaneously maintain a high quality of life, mainly in the presence of primary refractoriness, early progression and in later lines of therapy. In recent years, new targeted drugs have been studied – phosphoinositide 3-kinase, enhancer of zeste homolog 2 inhibitors, as well as immunological drugs (CAR-T therapy (CAR – chimeric antigen receptor) and bispecific antibodies).The article presents the possibilities of treatment for refractory/relapsed FL as 3rd and subsequent therapy lines.
