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.
Jonathan W. Riess, MD, of the University of California, Davis Comprehensive Cancer Center, explores the findings of three important clinical trials in lung cancer treatment: whether to incorporate immune checkpoint inhibitors into the treatment of EGFR-mutated lung cancer, the importance of central nervous system activity in EGFR-mutant lung cancer, and new therapies for disease with EGFR exon 20 insertion.
Cathy Eng, MD, of Vanderbilt-Ingram Cancer Center, and Thejus Jayakrishnan, MD, of the Cleveland Clinic Taussig Cancer Institute, discuss significant differences in the citrate cycle, a core pathway of cellular metabolism associated with colorectal cancer. Metabolomic differences impacted by environmental exposures (arginine biosynthesis and dietary red meat) were also noted, suggesting possible links with younger age of onset in this disease (Abstract 3510).
Amer Methqal Zeidan, MBBS, MHS, of Yale University and Yale Cancer Center, discusses phase III findings on the first-in-class telomerase inhibitor imetelstat, which was given to patients with heavily transfusion-dependent non-del(5q) lower-risk myelodysplastic syndromes that are resistant to erythropoiesis-stimulating agents. Imetelstat resulted in a significant and sustained red blood cell (RBC) transfusion independence in 40% of these heavily transfused patients. The response was also durable and accompanied by an impressive median hemoglobin rise of 3.6 g/dL, and seen in patients with and without ring sideroblasts. Importantly, reduced variant allele frequency was observed in the most commonly mutated myeloid genes which correlated with duration of transfusion independence and hemoglobin rise, therefore suggesting a disease-modifying potential of this agent (Abstract 7004).
Carmen E. Guerra, MD, MSCE, of the University of Pennsylvania Abramson Cancer Center, discusses three key abstracts presented at ASCO: strategies to increase accrual of underrepresented populations in Alliance NCTN trials, how patient-clinician education can strengthen partnerships and improve diversity in breast and lung cancer trials, and mediators of racial and ethnic inequities in clinical trial participation among U.S. patients with cancer from 2011 to 2022 (Abstracts 6509, 6510, 6511).
Bradley J. Monk, MD, of the University of Arizona, Phoenix, and Creighton University, discusses phase III findings from the KEYNOTE-826 study of overall survival results in patients with persistent, recurrent, or metastatic cervical cancer. Study participants received first-line treatment of pembrolizumab plus chemotherapy, with or without bevacizumab, which reduced the risk of death by up to 40% in three different subsets of patients (Abstract 5500).
