Systematic Literature Review Of The Clinical Evidence In Relapsed/Refractory (R/R) Large B-Cell Lymphoma

Introduction: Large B-cell lymphoma (LBCL) is the most common subtype of non-Hodgkin lymphoma. Frontline treatment is curative in ~60% of patients (pts); however, ~30% of pts relapse and ~10% are refractory to frontline treatment. Treatment options for pts with relapsed/refractory (R/R) disease, especially in the third-line or greater (3L+) setting, have been primarily salvage chemotherapies (CTs). Recently, 2 CAR T cell products, axicabtagene ciloleucel (Yescarta®) and tisagenlecleucel (Kymriah®), and the antibody-drug conjugate, polatuzumab vedotin (Polivy®), were approved in the 3L setting. A systematic literature review (SLR) of R/R LBCL was conducted to identify relevant evidence on clinical outcomes in LBCL pts, including these new therapies, within the second-line and greater (2L+) or 3L+ setting, and to define the unmet medical need.
