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.
Claire Roddie, PhD, MBChB, of University College London, discusses results of the FELIX study, which showed that the second-generation chimeric antigen receptor (CAR) T-cell therapy obecabtagene autoleucel is safe for adults with relapsed or refractory B-cell acute lymphoblastic leukemia, even those with a high burden of disease. This agent yielded high rates of complete response and ongoing CAR T-cell persistence in most patients whose disease responded (Abstract 7000).
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).
Smitha Krishnamurthi, MD, of the Cleveland Clinic, and Deb Schrag, MD, MPH, of Memorial Sloan Kettering Cancer Center, discuss phase III findings from the PROSPECT trial, which showed FOLFOX chemotherapy with selective use of radiation therapy and sensitizing fluoropyrimidine (5FUCRT) is noninferior to 5FUCRT for the neoadjuvant treatment of patients with locally advanced rectal cancer, prior to low anterior resection with total mesorectal excision (Abstract LBA2).
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).
Shailender Bhatia, MD, of the University of Washington and Fred Hutchinson Cancer Center, discusses phase I/II results on the efficacy of nivolumab with or without ipilimumab in patients with recurrent or metastatic Merkel cell carcinoma. The study found that, for this rare and aggressive skin cancer, nivolumab showed clinical activity in advanced disease. However, these results from CheckMate 358 do not suggest an additional benefit with ipilimumab added to nivolumab (Abstract 9506).
