Andrew D. Zelenetz, MD, PhD, and Michael L. Wang, MD, on Mantle Cell Lymphoma: New Data on Ibrutinib in Combination With Bendamustine/Rituximab and Rituximab Maintenance
2022 ASCO Annual Meeting
Andrew D. Zelenetz, MD, PhD, of Memorial Sloan Kettering Cancer Center, and Michael L. Wang, MD, of The University of Texas MD Anderson Cancer Center, discuss primary results from the phase III SHINE study, which showed that ibrutinib, in combination with bendamustine/rituximab and rituximab maintenance, may set a new benchmark for patients aged 65 or older with mantle cell lymphoma. With a median progression-free survival of 6.7 years, the ibrutinib combination is more beneficial than currently used chemoimmunotherapy (approximately 1.5–3.5 years) (Abstract LBA7502).
Akihiro Ohba, MD, of Japan’s National Cancer Center Hospital, discusses phase II data from the HERB trial on fam-trastuzumab deruxtecan-nxki, which showed activity in patients with HER2-expressing unresectable or recurrent biliary tract cancer (Abstract 4006).
Martin McCabe, PhD, of the University of Manchester, discusses a phase III assessment of chemotherapy for patients with recurrent and primary refractory Ewing sarcoma. The trial, called rEECur, is the first study to provide comparative toxicity and survival data for the four most commonly used chemotherapy regimens in this disease. The analysis showed that high-dose ifosfamide is more effective in prolonging survival than topotecan plus cyclophosphamide (Abstract LBA2).
Stephanie Walker, a former nurse and current activist with the Metastatic Breast Cancer Alliance, discusses findings from the BECOME project (Black Experience of Clinical Trials and Opportunities for Meaningful Engagement). They show that, even though Black patients comprise between 4% and 6% of all clinical trial participants, Black women with metastatic breast cancer are willing to consider taking part if steps were taken to increase their awareness, build trust through clear communication with health-care providers, involve people of shared racial/ethnic identity and health experience, and help patients find and access trials (Abstract 1014).
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).
Ann H. Partridge, MD, MPH, of Dana-Farber Cancer Institute, and Kevin Kalinsky, MD, of Winship Cancer Institute at Emory University, discuss phase II findings from the MAINTAIN trial, which showed a benefit in progression-free survival for patients with hormone receptor–positive/HER2-negative metastatic breast cancer when they switched to endocrine therapy and received ribociclib after disease progression on another CDK4/6 inhibitor (Abstract LBA1004).
