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).
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).
Nirav N. Shah, MD, of the Medical College of Wisconsin, discusses the efficacy and safety of pirtobrutinib, a highly selective, noncovalent BTK inhibitor, studied for more than 3 years in the BRUIN trial. The results showed that the use of pirtobrutinib continues to have durable efficacy and a favorable safety profile in heavily pretreated patients with relapsed or refractory mantle cell lymphoma and prior BTK inhibitor therapy. Responses were observed in patients with high-risk disease features, including blastoid/pleomorphic variants, elevated Ki67 index, and TP53 mutations (Abstract 7514).
Omid Hamid, MD, of The Angeles Clinic & Research Institute, discusses study findings on fianlimab plus cemiplimab-rwlc, which showed clinical activity in patients with advanced melanoma, comparing favorably with other approved combinations of immune checkpoint inhibitors in the same clinical setting. This is the first indication that dual LAG-3 blockade may produce a high level of activity with significant overall response rate after adjuvant anti–PD-1 treatment. A phase III trial of this regimen in treatment-naive patients with advanced melanoma is ongoing (Abstract 9501).
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).
