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.

Tycel J. Phillips, MD, and Alex F. Herrera, MD, both of the City of Hope National Medical Center, discuss findings from the POLARIX study, which provided the largest prospectively collected circulating tumor DNA (ctDNA) data set on patients with previously untreated diffuse large B-cell lymphoma. Achieving ctDNA-negative status was associated with improved outcomes when patients were treated with polatuzumab vedotin-piiq plus combination chemotherapy vs combination chemotherapy alone (Abstract 7523).

Jennifer L. Crombie, MD, of Dana-Farber Cancer Institute, discusses the historically poor outcomes for patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL). Her study examined real-world data on the use of novel therapies in this population and found that outcomes with second- and third-line regimens of polatuzumab vedotin-piiq plus bendamustine and rituximab and tafasitamab plus lenalidomide remain suboptimal, with worse outcomes particularly after chimeric antigen receptor T-cell therapy (Abstract 7552).

Jonathan W. Riess, MD, of the University of California, Davis Comprehensive Cancer Center, explores the findings of three important clinical trials in lung cancer treatment: whether to incorporate immune checkpoint inhibitors into the treatment of EGFR-mutated lung cancer, the importance of central nervous system activity in EGFR-mutant lung cancer, and new therapies for disease with EGFR exon 20 insertion.

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).

Narjust Florez, MD, of Dana-Farber Cancer Institute, and Ferdinandos Skoulidis, MD, PhD, of The University of Texas MD Anderson Cancer Center, discuss results of a biomarker subgroup analysis, showing that sotorasib demonstrated consistent clinical benefit vs docetaxel in all molecularly defined subgroups of patients with pretreated KRAS G12C–mutated advanced non–small cell lung cancer (NSCLC). Although no predictive biomarkers were confirmed, novel hypothesis-generating signals were observed (Abstract 9008).
