Eileen M. Boyle, MD, PhD, of the Perlmutter Cancer Center, NYU Langone Health, discusses Fc-mediated antibody effector function, inflammation resolution, and oligoclonality and their role in predicting sustained measurable residual disease negativity in patients with newly diagnosed multiple myeloma who were treated with immunotherapy regimens. For the first time, an analysis of T-cell receptors shows that oligoclonal profiles seen on treatment may influence the fitness of the immune response (Abstract 100).
Stephen M. Ansell, MD, PhD, and Patrizia Mondello, MD, PhD, both of the Mayo Clinic, discuss the 20% of patients with follicular lymphoma (FL) who relapse early and experience a poor prognosis. The researchers found that FLs with high levels of IRF4 expression are associated with a suppressive tumor microenvironment, and selective IRF4 silencing restores antilymphoma T-cell immunity. Further investigation is warranted to identify the mechanisms by which IRF4 controls tumor immunity to develop precision therapies for this population (Abstract 70).
Elias Jabbour, MD, of The University of Texas MD Anderson Cancer Center, discusses an analysis confirming that olverembatinib is a potentially viable treatment option for patients with chronic myeloid leukemia (CML) and Philadelphia chromosome–positive acute lymphoblastic leukemia (ALL), including those with CML whose disease did not respond to ponatinib or asciminib, or who had a T315I mutation (Abstract 82).
Paul G. Richardson, MD, of the Dana-Farber Cancer Institute, discusses preliminary results from the dose-expansion phase of the CC-92480-MM-001 Trial, which showed promising efficacy in patients with relapsed and refractory multiple myeloma, including those with prior BCMA-targeted therapies. Patients in these two groups had an overall response rate of 40% and 50%, respectively. The results support the development of mezigdomide, currently being evaluated in combination with standard therapies in multiple myeloma as part of a large, ongoing phase I/II trial (NCT03989414) and planned phase III studies (Abstract 568).
Anand P. Jillella, MD, of Georgia Cancer Center at Augusta University, discusses results from the ECOG-ACRIN EA9131 Trial, which showed that using a simplified treatment algorithm and management recommendations made by a group of specialists, resulted in a dramatic improvement in 1-year survival of patients with acute promyelocytic leukemia (Abstract 421).
