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.
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).
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).
Guillermo Garcia-Manero, MD, of The University of Texas MD Anderson Cancer Center, discusses phase III findings from the COMMANDS trial. Compared with epoetin alfa, luspatercept improved red blood cell transfusion independence and erythroid response, as well as the duration of response in erythropoiesis-stimulating agent–naive, transfusion-dependent patients with lower‐risk myelodysplastic syndromes (Abstract 7003).
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).
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).
