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.

Aaron T. Gerds, MD, of Cleveland Clinic Taussig Cancer Institute, talks about treating the anemia many patients with myelofibrosis experience because of JAK inhibitor therapy. The ACE-536-MF-001 study showed that luspatercept improved anemia and transfusion burden in this population, with a safety profile consistent with that in previous studies (Abstract 7016).

Narjust Florez, MD, of Dana-Farber Cancer Institute, and Filippo Gustavo Dall’Olio, MD, of Institut Gustave Roussy, discuss circulating tumor DNA tumor fraction, and its link to survival in patients with advanced non–small cell lung cancer (NSCLC) treated with maintenance durvalumab in the UNICANCER SAFIR02-Lung/IFCT1301 trial. Tumor fraction was positive in 16% of patients randomly assigned to receive durvalumab in the study. This population seems to have a limited benefit from maintenance durvalumab after induction chemotherapy (Abstract 2516).

Omid Hamid, MD, of The Angeles Clinic & Research Institute, discusses study findings on fianlimab plus cemiplimab-rwlc, which showed clinical activity in patients with advanced melanoma, comparing favorably with other approved combinations of immune checkpoint inhibitors in the same clinical setting. This is the first indication that dual LAG-3 blockade may produce a high level of activity with significant overall response rate after adjuvant anti–PD-1 treatment. A phase III trial of this regimen in treatment-naive patients with advanced melanoma is ongoing (Abstract 9501).

Lisa M. DeAngelis, MD, and Ingo K. Mellinghoff, MD, both of Memorial Sloan Kettering Cancer Center, discuss findings from the INDIGO trial showing that the IDH1/2 inhibitor vorasidenib improves progression-free survival for patients with residual or recurrent grade 2 glioma with an IDH1/2 mutation. These data demonstrate the clinical benefit of vorasidenib in this patient population for whom chemotherapy and radiotherapy are being delayed.

Paula Aristizabal, MD, MAS, of the University of California, San Diego, and Rady Children’s Hospital, talks about using a health systems strengthening approach to improve leukemia care and survival in a public Mexican hospital in the region of the border between the United States and Mexico. The demonstrated increase in overall survival across a decade after implementation of the program seems to validate the use of such models, not only to improve clinical outcomes, but also to build sustainable hospital capacity, financially and organizationally (Abstract 1502).
