Dr. Krish Patel from the Swedish Cancer Institute discusses novel therapies for DLBCL, focusing on bispecific antibody gilteritinib. They compare bispecifics to CAR T-cell therapy, explore fixed duration therapy, step-up dosing, and sequencing therapy for optimal results.
Frontline therapy shifts towards using Polatuzumab-based therapy for non-GCB DLBCL patients following positive Polaris trial data.
Bispecific antibodies like Polatuzumab show efficacy in third-line DLBCL treatment with potential for combination therapies.
Deep dives
The Evolution of Frontline Therapy for Diffuse Large B Cell Lymphoma
Frontline therapy for diffuse large B cell lymphoma (DLBCL) has seen significant changes, particularly with the introduction of the Polaris trial data, comparing R-Chop to R-Chop with Polatuzumab. The data showed benefits of Polatuzumab-based therapy, especially in non-germinal center B cell DLBCL. This led to a shift towards using Polatuzumab-based therapy, particularly for non-GCB patients, with ongoing monitoring of the treatment's long-term benefits.
The Role of Bispecific Antibodies in Treating DLBCL and Patient Considerations
Bispecific antibodies are a promising class of treatments in oncology, including in diffuse large B cell lymphoma (DLBCL). These antibodies target a tumor antigen while engaging immune effector cells to promote immune-mediated killing. Notable examples include CD3 and CD20 targeting antibodies like Polatuzumab. The approval of drugs like Polatuzumab in third-line DLBCL treatment showcases their efficacy, with considerations for both fixed-duration therapy and patient quality of life.
Future Directions and Combinations with Bispecific Antibodies
The future of bispecific antibodies in DLBCL and beyond looks promising, especially in combination with other immunomodulatory therapies like lenalidomide. Trials are exploring novel combinations, potentially enhancing the efficacy of bispecific antibodies in various lymphoma histologies. The ability to combine these antibodies with CAR-T cells adds further versatility to their use, opening avenues for more personalized and effective treatment approaches.
Dr. Patel, of the Swedish Cancer Institute in Seattle, Washington, joins Chadi Nabhan, MD, MBA, FACP, on “The HemOnc Pulse” to discuss novel frontline therapies in the lymphoma space, including the bispecific antibody glofitamab.
They also discuss bispecifics versus chimeric antigen receptor (CAR) T-cell therapy, fixed duration therapy and step-up dosing, and how to sequence therapy.
