Thomas E. Hutson, DO, PharmD, on RCC: Overall Survival Analysis of Lenvatinib, Pembrolizumab, and Sunitinib
2023 ASCO Annual Meeting
Thomas E. Hutson, DO, PharmD, of Texas Oncology, discusses the 4-year follow-up results from the CLEAR study for patients with advanced renal cell carcinoma (RCC). The data showed that lenvatinib plus pembrolizumab continues to demonstrate clinically meaningful benefit vs sunitinib in overall and progression-free survival, as well as in overall and complete response rates, in first-line treatment (Abstract 4502).

Thomas E. Hutson :
On behalf of my co-investigators, I presented the final pre-specified overall survival from the Phase 3 CLEAR study with nearly four years follow up. The Phase 3 CLEAR study was an international randomized trial comparing Lenvatinib pembrolizumab, Lenvatinib everolimus versus Sunitinib as first-line therapy for patients with advanced renal cell carcinoma.
This data had previously been reported when it met its primary efficacy endpoint, which was improvement in progression-free survival. At that time of that presentation, the secondary endpoints of overall survival and objective response rates were also statistically significant. This resulted in regulatory approval of this regimen and rapid incorporation of this regimen as a major frontline therapy option for patients with advanced RCC throughout the world. This information was also previously published in the New England Journal of Medicine.
Now, with additional 23 months follow up, pleased to report that our overall survival is maintained with a hazard ratio of 0.79, and our other efficacy signals such as progression-free survival and response rate remain robust with this longer follow-up. There were also no new additional safety signals.
So in conclusion, we're pleased to report with additional nearly four years of follow-up the overall survival progression-free survival and objective response rates remain significant and robust when compared with Sunitinib with no new safety signals of the regimen. And Pembrolizumab and Lenvatinib remain a primary therapy for patients with advanced RCC.

Jennifer A. Woyach, MD, of The Ohio State University Comprehensive Cancer Center, discusses results of a phase III study showing that progression-free survival with ibrutinib plus obinutuzumab plus venetoclax is not superior to ibrutinib plus obinutuzumab for treatment-naive older patients with chronic lymphocytic leukemia (CLL) in the setting of the COVID-19 pandemic. Long-term follow-up will determine whether there are advantages to obinutuzumab plus venetoclax, with special attention to measurable residual disease and therapy discontinuation (Abstract 7500).

Narjust Florez, MD, of Dana-Farber Cancer Institute, and Ticiana Leal, MD, of Winship Cancer Institute of Emory University, discuss the use of tumor treating fields therapy, in which electric fields disrupt processes critical for cancer cell viability. Already approved by the FDA to treat glioblastoma and mesothelioma, the treatment has extended overall survival in this phase III study of patients with metastatic non–small cell lung cancer (NSCLC) with progression on or after platinum-based chemotherapy, without exacerbating systemic toxicities (Abstract LBA9005).

Sarah K. Tasian, MD, of Children’s Hospital of Philadelphia, summarizes three studies presented at ASCO: genomic determinants of outcome in acute lymphoblastic leukemia (ALL), a phase III trial of inotuzumab ozogamicin for high-risk B-cell ALL, and preliminary results from the first-in-child phase II trial of bosutinib in pediatric patients with newly diagnosed chronic myeloid leukemia (Abstracts 10015, 10016, and 10017).

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).

Manali K. Kamdar, MD, of University of Colorado Hospital, discusses the treatment landscape for the 30% to 40% of patients with diffuse large B-cell lymphoma (DLBCL) whose disease will relapse. Patients who experience relapse within 1 year of chemoimmunotherapy have poor outcomes with autotransplantation, but chimeric antigen receptor T-cell therapy has shown efficacy and manageable toxicity.
