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.
Alicia K. Morgans, MD, MPH, of Dana-Farber Cancer Institute, and Karim Fizazi, MD, of Institut Gustave Roussy, University of Paris-Saclay, discuss findings from the TALAPRO-2 study, which showed that talazoparib plus enzalutamide improved radiographic progression–free survival over standard-of-care enzalutamide as first-line treatment for patients with metastatic castration-resistant prostate cancer and HRR gene alterations. This regimen also delayed the time to deterioration in global health status and quality of life (Abstract 5004).
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).
Thierry Conroy, MD, of the Institut de Cancérologie de Lorraine, discusses phase III findings from the PRODIGE 23 trial, showing that neoadjuvant chemotherapy with mFOLFIRINOX followed by chemoradiotherapy, surgery, and adjuvant chemotherapy improved all outcomes, including overall survival, in patients with locally advanced rectal cancer compared with standard chemoradiotherapy, surgery, and adjuvant chemotherapy (Abstract LBA3504).
Alberto Bossi, MD, of Institut Gustave Roussy, discusses phase III findings showing that combining prostate radiotherapy with systemic treatment did not improve overall survival in men with de novo metastatic castration-sensitive prostate cancer and low metastatic burden. However, best outcomes (radiographic progression–free-survival and overall survival) were observed in men receiving the standard of care plus abiraterone acetate plus prednisone with radiotherapy (Abstract LBA5000).
Narjust Florez, MD, of Dana-Farber Cancer Institute, and Ferdinandos Skoulidis, MD, PhD, of The University of Texas MD Anderson Cancer Center, discuss results of a biomarker subgroup analysis, showing that sotorasib demonstrated consistent clinical benefit vs docetaxel in all molecularly defined subgroups of patients with pretreated KRAS G12C–mutated advanced non–small cell lung cancer (NSCLC). Although no predictive biomarkers were confirmed, novel hypothesis-generating signals were observed (Abstract 9008).
