Paul G. Richardson, MD, on Multiple Myeloma: New Data on Lenalidomide, Bortezomib, and Dexamethasone, With or Without ASCT
2022 ASCO Annual Meeting
Paul G. Richardson, MD, of Dana-Farber Cancer Institute, discusses phase III findings from the DETERMINATION trial, which showed that, for patients with newly diagnosed multiple myeloma, lenalidomide, bortezomib, and dexamethasone (RVd) with or without autologous stem cell transplant (ASCT) and lenalidomide maintenance to disease progression resulted in the longest median progression-free survival reported for each approach, and a highly significant difference in progression-free survival in favor of early transplant. While overall response rates were similar, rates of MRD favored early transplant also, but toxicity was greater and quality of life was transiently but significantly diminished. No overall survival advantage has been observed to date (Abstract LBA4).
Alfredo Carrato, MD, PhD, of Alcala de Henares University in Spain, discusses phase II results from the SEQUENCE trial, which showed that nab-paclitaxel, gemcitabine, and modified FOLFOX showed significantly higher clinical activity than the standard nab-paclitaxel and gemcitabine in the first-line setting of patients with untreated metastatic pancreatic ductal adenocarcinoma (Abstract 4022).
Etienne Brain, MD, PhD, of the Institut Curie, discusses phase III findings from the Unicancer ASTER 70s trial, in which patients aged 70 or older with estrogen receptor–positive, HER2-negative breast cancer and a high genomic grade index received adjuvant endocrine therapy with or without chemotherapy. The data did not find a statistically significant overall survival benefit with this treatment after surgery (Abstract 500).
Shilpa Gupta, MD, of the Cleveland Clinic Foundation, discusses an updated consensus definition for standard therapy and clinical trial eligibility for patients with metastatic urothelial cancer who are platinum-ineligible, criteria that are proposed to guide treatment recommendations for this population. This may be especially important now that the U.S. Food and Drug Administration has restricted the use of first-line pembrolizumab to those who are considered platinum-ineligible (Abstract 4577).
Pamela L. Kunz, MD, of the Yale University School of Medicine, discusses new findings from the ECOG-ACRIN E2211 trial, which showed the longest progression-free survival and highest response rates with temozolomide plus capecitabine reported to date for patients with pancreatic neuroendocrine tumors. The presence of a deficiency of MGMT, the drug-resistance gene, was associated with greater odds of an objective response (Abstract 4004).
Mairéad G. McNamara, PhD, MBBCh, of The Christie NHS Foundation Trust, discusses phase II findings of the NET-02 trial, which explored an unmet need in the second-line treatment of patients with progressive, poorly differentiated extrapulmonary neuroendocrine carcinoma. In the trial, the combination of liposomal irinotecan, fluorouracil, and folinic acid, but not docetaxel, met the primary endpoint of 6-month progression-free survival rate (Abstract 4005).
