Abstract
In the phase 3 CLEAR trial, lenvatinib plus pembrolizumab (L + P) showed superior efficacy versus sunitinib in treatment-naïve patients with advanced renal cell carcinoma (aRCC). The combination treatment was associated with a robust objective response rate of 71%. Here we report tumor responses for patients in the L + P arm in CLEAR, with median follow-up of ∼4 yr at the final prespecified overall survival (OS) analysis. Tumor responses were assessed by independent review using Response Evaluation Criteria in Solid Tumors v1.1. Patients with a complete response (CR; n = 65), partial response (PR) with maximum tumor shrinkage ≥75% (near-CR; n = 59), or PR with maximum tumor shrinkage <75% (other PR; n = 129), were characterized in terms of their baseline characteristics. The median duration of response was 43.7 mo (95% confidence interval [CI] 39.2–not estimable) for the CR group, 30.5 mo (95% CI 22.4–not estimable) for the near-CR group, and 17.2 mo (95% CI 12.5–21.4) for the other PR group. The 36-mo OS rates were consistently high in the CR (97%), near-CR (86%), and other PR (62%) groups. Robust objective response rates were observed across International Metastatic RCC Database Consortium favorable-risk (69%, 95% CI 60–78%), intermediate-risk (73%, 95% CI 67–79%), and poor-risk (70%, 95% CI 54–85%) subgroups. The robust response to L + P supports this combination as a standard-of-care first-line treatment for patients with aRCC.
Patient summary
The CLEAR trial enrolled patients with advanced kidney cancer who had not previously received any treatment for their cancer. Here we report results for tumor shrinkage observed in the group that received lenvatinib plus pembrolizumab combination treatment during the trial. Shrinkage of target tumors with this combination was long-lasting and was observed in patients irrespective of their disease severity.
This trial is registered on ClinicalTrials.gov as NCT02811861.
期刊介绍:
European Urology is a peer-reviewed journal that publishes original articles and reviews on a broad spectrum of urological issues. Covering topics such as oncology, impotence, infertility, pediatrics, lithiasis and endourology, the journal also highlights recent advances in techniques, instrumentation, surgery, and pediatric urology. This comprehensive approach provides readers with an in-depth guide to international developments in urology.
