Ajay K. Nooka, MBBS, of Winship Cancer Center of Emory University, discusses phase II findings showing that, in patients with high-risk myeloma, maintenance therapy with carfilzomib, pomalidomide, and dexamethasone deepened responses. Measurable residual disease negativity was attained in 80% of patients.
Sebastian Stintzing, MD, of the Charité Universitätsmedizin Berlin, discusses results from the phase III FIRE-4 study, which showed that liquid biopsy is clinically relevant in verifying mutational status in patients with metastatic colorectal cancer and is efficacious in first-line treatment of FOLFIRI and cetuximab for patients with RAS wild-type disease (Abstract 3507).
Catherine C. Coombs, MD, of the University of California, Irvine, discusses prolonged pirtobrutinib therapy, which continues to demonstrate a safety profile amenable to long-term administration at the recommended dose without evidence of new or worsening toxicity signals. The safety and tolerability observed in patients on therapy for 12 months or more were similar to previously published safety analyses of all patients enrolled, regardless of follow-up (Abstract 7513).
LaQuisa C. Hill, MD, of Baylor College of Medicine, Houston Methodist Hospital, discusses study findings showing that CD5 chimeric antigen receptor (CAR) T cells may induce clinical responses in heavily treated patients with relapsed or refractory T-cell acute lymphoblastic leukemia. Manufacturing CD5 CAR T cells with tyrosine kinase inhibitors seemed to improve their potency and antitumor activity (Abstract 7002).
Tycel J. Phillips, MD, and Alex F. Herrera, MD, both of the City of Hope National Medical Center, discuss findings from the POLARIX study, which provided the largest prospectively collected circulating tumor DNA (ctDNA) data set on patients with previously untreated diffuse large B-cell lymphoma. Achieving ctDNA-negative status was associated with improved outcomes when patients were treated with polatuzumab vedotin-piiq plus combination chemotherapy vs combination chemotherapy alone (Abstract 7523).
Christian Pfister, MD, PhD, of Rouen University Hospital, discusses phase III results from the VESPER trial, which showed that dose-dense methotrexate, vinblastine, doxorubicin, and cisplatin provided a better overall survival rate at 5 years and improved disease-specific survival compared with gemcitabine as perioperative chemotherapy in patients with muscle-invasive bladder cancer (Abstract LBA4507).
