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.

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).

Penelope Bradbury, MBChB, of Canada’s Princess Margaret Cancer Centre, discusses phase III findings showing that, in patients with treatment-naive unresectable pleural mesothelioma, cisplatin and pemetrexed with pembrolizumab improved median overall survival with acceptable tolerability (Abstract LBA8505).

Amer Methqal Zeidan, MBBS, MHS, of Yale University and Yale Cancer Center, discusses phase III findings on the first-in-class telomerase inhibitor imetelstat, which was given to patients with heavily transfusion-dependent non-del(5q) lower-risk myelodysplastic syndromes that are resistant to erythropoiesis-stimulating agents. Imetelstat resulted in a significant and sustained red blood cell (RBC) transfusion independence in 40% of these heavily transfused patients. The response was also durable and accompanied by an impressive median hemoglobin rise of 3.6 g/dL, and seen in patients with and without ring sideroblasts. Importantly, reduced variant allele frequency was observed in the most commonly mutated myeloid genes which correlated with duration of transfusion independence and hemoglobin rise, therefore suggesting a disease-modifying potential of this agent (Abstract 7004).

Reid Merryman, MD, of Dana-Farber Cancer Institute, discusses his findings on the regimen of epcoritamab plus rituximab and lenalidomide for patients with high-risk follicular lymphoma. Regardless of whether their disease progressed within 24 months of first-line chemoimmunotherapy, this regimen showed antitumor activity and a manageable safety profile in patients with relapsed or refractory disease. Epcoritamab, a subcutaneous T-cell–engaging bispecific antibody, may abrogate the negative effects of high-risk features (Abstract 7506).

Jason J. Luke, MD, of the University of Pittsburgh Medical Center Hillman Cancer Center, discusses adjuvant pembrolizumab, which, in previous results, improved distant metastasis– and recurrence-free survival in patients with resected stage IIB or IIC melanoma vs placebo. After a median follow-up of 39.4 months, adjuvant pembrolizumab continued to show a benefit over placebo, with no new safety signals (Abstract LBA9505).
