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.

Enrique Grande, MD, of The University of Texas MD Anderson Cancer Center, discusses new findings that show initial responses to induction therapy with atezolizumab plus platinum and gemcitabine did not seem to impact overall survival for patients with metastatic urothelial carcinoma. Cisplatin-treated patients appeared to derive a greater benefit with atezolizumab than did carboplatin-treated patients (Abstract 4503).

Nirav N. Shah, MD, of the Medical College of Wisconsin, discusses the efficacy and safety of pirtobrutinib, a highly selective, noncovalent BTK inhibitor, studied for more than 3 years in the BRUIN trial. The results showed that the use of pirtobrutinib continues to have durable efficacy and a favorable safety profile in heavily pretreated patients with relapsed or refractory mantle cell lymphoma and prior BTK inhibitor therapy. Responses were observed in patients with high-risk disease features, including blastoid/pleomorphic variants, elevated Ki67 index, and TP53 mutations (Abstract 7514).

James Chih-Hsin Yang, MD, PhD, of the National Taiwan University Hospital and National Taiwan University Cancer Center, discusses the latest data from the phase III KEYNOTE-789 study, which evaluated the efficacy and safety of pemetrexed plus platinum chemotherapy (carboplatin or cisplatin) with or without pembrolizumab in the treatment of adults with EGFR tyrosine kinase inhibitor–resistant, EGFR–mutated, metastatic nonsquamous non–small cell lung cancer (NSCLC) (Abstract LBA9000).

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).

Lisa A. Carey, MD, of the University of North Carolina at Chapel Hill, and Dennis J. Slamon, MD, PhD, of the University of California, Los Angeles, discuss phase III study findings on ribociclib plus endocrine therapy as adjuvant treatment in patients with hormone receptor–positive, HER2-negative early breast cancer. When added to standard-of-care endocrine therapy, ribociclib improved invasive disease–free survival with a well-tolerated safety profile (Abstract LBA500).
