Lenvatinib plus pembrolizumab significantly improved efficacy versus sunitinib in treatment of advanced renal cell carcinoma (aRCC) in the phase 3 CLEAR study. We report results of an exploratory post hoc analysis of tumor response data based on baseline metastatic characteristics of patients who received lenvatinib plus pembrolizumab versus sunitinib, at the final overall survival analysis time point of CLEAR (cutoff: July 31, 2022). Treatment-naïve adults with aRCC were randomized to: lenvatinib (20 mg PO QD in 21-day cycles) plus pembrolizumab (n = 355; 200 mg IV Q3W); lenvatinib plus everolimus (not reported here); or sunitinib (n = 357; 50 mg PO QD; 4 weeks on/2 weeks off). The most common (lenvatinib plus pembrolizumab; sunitinib, respectively) metastatic site was lung (71.0%; 63.9%), followed by lymph node (45.6%; 43.7%), bone (22.5%; 24.9%), and liver (17.7%; 19.6%). Across treatment arms, ≥65% had two or more metastatic organs/sites involved, >80% of patients had nontarget lesions, and ~45% had baseline sums of diameters of target lesions ≥60 mm. Lenvatinib plus pembrolizumab demonstrated greater progression-free survival, objective response rate, and duration of response versus sunitinib across evaluable subgroups regardless of site or size of baseline metastasis or number of metastatic sites at baseline. Overall survival generally trended to favor lenvatinib plus pembrolizumab versus sunitinib; and tumor shrinkage was greater across sites (lung, lymph node, liver, and bone) for patients in the lenvatinib-plus-pembrolizumab arm versus the sunitinib arm. These results further support lenvatinib plus pembrolizumab as a standard-of-care in patients with aRCC regardless of site or size of baseline metastasis or the number of metastatic sites.

INTRODUCTION: Renal cell carcinoma (RCC) is one of the most common types of urogenital cancer. The introduction of immune-based combinations, including dual immune-checkpoint inhibitors (ICI) or ICI plus tyrosine kinase inhibitors (TKIs), has radically changed the treatment landscape for metastatic RCC, showing varying efficacy across different prognostic groups based on the International Metastatic RCC Database Consortium (IMDC) criteria. MATERIALS AND METHODS: This retrospective multicenter study, part of the ARON-1 project, aimed to evaluate the outcomes of favorable-risk metastatic RCC patients treated with immune-based combinations or sunitinib. Patients were assessed for overall survival (OS), progression-free survival (PFS) and overall response rate. We carried out a survival analysis by a Cox regression model. RESULTS: A total of 524 favorable-risk patients were included in the analysis. After a median follow-up of 37.2 months, the median OS in the overall population was 56.1 months. There was no significant difference in OS between patients receiving sunitinib and those receiving TKI + ICI combinations (p = 0.761). Patients on TKI + ICI had significantly longer PFS compared to patient treated with sunitinib (30.7 vs 22.9 months, p = 0.007). Analysis of OS and PFS based on metastatic site revealed that patients with bone metastases benefited more from ICI plus TKI (56 patients with bone metastases receiving IO + TKI, 38 received pembrolizumab plus axitinib, 15 cabozantinib plus nivolumab and 3 pembrolizumab plus lenvatinib), while sunitinib was more effective for pancreatic and glandular metastases. Additionally, the number of metastatic sites played a role, with TKI plus ICI showing superiority in patients with a single metastatic site. The time from RCC diagnosis to metastatic disease also impacted outcomes, with TKI plus ICI being more effective in patients with a shorter interval (i.e., < 36 months). CONCLUSIONS: The choice between upfront combination or monotherapy for metastatic favorable prognosis RCC remains a current issue. While combination therapy offers prolonged PFS, it does not necessarily translate to improve OS compared to sunitinib. This real-world study supports the superiority in terms of PFS of TKI plus ICI vs TKI monotherapy but not in OS. Probable, other clinical factors should be taking into account to make clinical treatment decisions in this setting.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical trial updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.We present the final prespecified overall survival (OS) analysis of the open-label, phase III CLEAR study in treatment-naïve patients with advanced renal cell carcinoma (aRCC). With an additional follow-up of 23 months from the primary analysis, we report results from the lenvatinib plus pembrolizumab versus sunitinib comparison of CLEAR. Treatment-naïve patients with aRCC were randomly assigned to receive lenvatinib (20 mg orally once daily in 21-day cycles) plus pembrolizumab (200 mg intravenously once every 3 weeks) or sunitinib (50 mg orally once daily [4 weeks on/2 weeks off]). At this data cutoff date (July 31, 2022), the OS hazard ratio (HR) was 0.79 (95% CI, 0.63 to 0.99). The median OS (95% CI) was 53.7 months (95% CI, 48.7 to not estimable [NE]) with lenvatinib plus pembrolizumab versus 54.3 months (95% CI, 40.9 to NE) with sunitinib; 36-month OS rates (95% CI) were 66.4% (95% CI, 61.1 to 71.2) and 60.2% (95% CI, 54.6 to 65.2), respectively. The median progression-free survival (95% CI) was 23.9 months (95% CI, 20.8 to 27.7) with lenvatinib plus pembrolizumab and 9.2 months (95% CI, 6.0 to 11.0) with sunitinib (HR, 0.47 [95% CI, 0.38 to 0.57]). Objective response rate also favored the combination over sunitinib (71.3% v 36.7%; relative risk 1.94 [95% CI, 1.67 to 2.26]). Treatment-emergent adverse events occurred in >90% of patients who received either treatment. In conclusion, lenvatinib plus pembrolizumab achieved consistent, durable benefit with a manageable safety profile in treatment-naïve patients with aRCC.

Previous analyses of KEYNOTE-426, an open-label, phase 3 randomized study, showed superior efficacy of first-line pembrolizumab plus axitinib to sunitinib in advanced clear cell renal cell carcinoma (ccRCC). We report results of the final protocol-prespecified analysis of KEYNOTE-426. Patients received pembrolizumab 200 mg intravenously every 3 wk plus axitinib 5 mg orally twice daily or sunitinib 50 mg orally once daily (4 wk per 6-wk cycle). The dual primary endpoints were overall survival (OS) and progression-free survival (PFS) as per RECIST v1.1 by a blinded independent central review. The secondary endpoints included objective response rate (ORR) and duration of response (DOR). The median study follow-up was 43 (range, 36-51) mo. Benefit with pembrolizumab plus axitinib versus sunitinib was maintained for OS (hazard ratio [HR], 0.73 [95% confidence interval {CI}, 0.60-0.88]), PFS (HR, 0.68 [95% CI, 0.58-0.80]), and ORR (60% vs 40%). The median DOR was 24 (range, 1.4+ to 43+) versus 15 (range, 2.3-43+) mo in the pembrolizumab plus axitinib versus the sunitinib arm. No new safety signals emerged. These results support pembrolizumab plus axitinib as a standard of care for patients with previously untreated advanced ccRCC. PATIENT SUMMARY: Extended results of KEYNOTE-426 support pembrolizumab plus axitinib as the standard of care for advanced clear cell renal cell carcinoma.

Aim: To compare the efficacy of first-line immune checkpoint inhibitor (ICI)-based combinations in metastatic renal cell carcinoma (mRCC) patients stratified by chronological age. Methods: According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, hazard ratios for overall survival (OS) from randomized controlled trials were synthesized. Results: Five RCTs were eligible for meta-analyses. ICI-based combinations significantly improved OS compared with sunitinib alone, both in younger (<65 years) and older (≥65 years) patients, whereas the OS benefit was significantly better in younger patients (p = 0.007). ICI-based combinations did not improve OS in patients aged ≥75 years. Treatment rankings showed age-related differential recommendations regarding improved OS. Conclusion: OS benefit from first-line ICI-based combinations was significantly greater in younger patients. Age-related differences could help enrich shared decision-making.

Scientists have found a special way to treat a type of cancer called metastatic renal cell carcinoma. They use a combination of medicines that help the body's immune system fight cancer. These treatments are very effective and recommended as the first choice for patients with this type cancer. However, as people get older, their immune systems may not work as well. Studies looking at how these treatments work in different age groups, and it was discovered that these treatments improved the chances of survival for all patients, no matter their age. However, they also noticed that younger patients got even more benefits from the treatments. Because of these discoveries, doctors can now make better decisions about which treatment to use for patients with this type of cancer, depending on patient age.

In the CLEAR trial, lenvatinib plus pembrolizumab met study endpoints of superiority vs sunitinib in the first-line treatment of patients with advanced renal cell carcinoma. We report the efficacy and safety results of the East Asian subset (ie, patients in Japan and the Republic of Korea) from the CLEAR trial. Of 1069 patients randomly assigned to receive either lenvatinib plus pembrolizumab, lenvatinib plus everolimus or sunitinib, 213 (20.0%) were from East Asia. Baseline characteristics of patients in the East Asian subset were generally comparable with those of the global trial population. In the East Asian subset, progression-free survival was considerably longer with lenvatinib plus pembrolizumab vs sunitinib (median 22.1 vs 11.1 months; HR 0.38; 95% CI: 0.23-0.62). The HR for overall survival comparing lenvatinib plus pembrolizumab vs sunitinib was 0.71; 95% CI: 0.30-1.71. The objective response rate was higher with lenvatinib plus pembrolizumab vs sunitinib (65.3% vs 49.2%; odds ratio 2.14; 95% CI: 1.07-4.28). Dose reductions due to treatment-emergent adverse events (TEAEs) commonly associated with tyrosine kinase inhibitors occurred more frequently than in the global population. Hand-foot syndrome was the most frequent any-grade TEAE with lenvatinib plus pembrolizumab (66.7%) and sunitinib (57.8%), a higher incidence compared to the global population (28.7% and 37.4%, respectively). The most common grade 3 to 5 TEAEs were hypertension with lenvatinib plus pembrolizumab (20%) and decreased platelet count with sunitinib (21.9%). Efficacy and safety for patients in the East Asian subset were generally similar to those of the global population, except as noted.

BACKGROUND: The extent of tumor shrinkage has been deemed a predictor of survival for advanced/metastatic renal cell carcinoma (RCC), a disease with historically poor survival. OBJECTIVE: To perform an exploratory analysis of overall survival (OS) by tumor response by 6 mo, and to assess the efficacy and survival outcomes in specific subgroups. DESIGN, SETTING, AND PARTICIPANTS: CLEAR was an open-label, multicenter, randomized, phase 3 trial of first-line treatment of advanced clear cell RCC. INTERVENTION: Patients were randomized 1:1:1 to lenvatinib 20 mg orally daily with pembrolizumab 200 mg intravenously once every 3 wk, lenvatinib plus everolimus (not included in this analysis), or sunitinib 50 mg orally daily for 4 wk on treatment/2 wk of no treatment. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Landmark analyses were conducted to assess the association of OS with tumor shrinkage and progressive disease status by 6 mo. Progression-free survival, duration of response, and objective response rate (ORR) were analyzed by the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk subgroup and by the presence of target kidney lesions. Efficacy was assessed by an independent review committee as per Response Evaluation Criteria in Solid Tumors version 1.1. RESULTS AND LIMITATIONS: Landmark analyses by tumor shrinkage showed that patients enrolled to lenvatinib plus pembrolizumab arm with a confirmed complete response or >75% target-lesion reduction by 6 mo had a 24-mo OS probability of ≥91.7%. A landmark analysis by disease progression showed that patients with no progression by 6 mo had lower probabilities of death in both arms. Patients with an IMDC risk classification of intermediate/poor had longer median progression-free survival (22.1 vs 5.9 mo) and a higher ORR (72.4% vs 28.8%) with lenvatinib plus pembrolizumab versus sunitinib. Similarly, results favored lenvatinib plus pembrolizumab in IMDC-favorable patients and those with/without target kidney lesions. Limitations of the study are that results were exploratory and not powered/stratified. CONCLUSIONS: Lenvatinib plus pembrolizumab showed improved efficacy versus sunitinib for patients with advanced RCC; landmark analyses showed that tumor response by 6 mo correlated with longer OS. PATIENT SUMMARY: In this report of the CLEAR trial, we explored the survival of patients with advanced renal cell carcinoma by assessing how well they initially responded to treatment. We also explored how certain groups of patients responded to treatment overall. Patients were assigned to cycles of either lenvatinib 20 mg daily plus pembrolizumab 200 mg every 3 wk or sunitinib 50 mg daily for 4 wk (followed by a 2-wk break). Patients who either had a "complete response" or had their tumors shrunk by >75% within 6 mo after starting treatment with lenvatinib plus pembrolizumab had better survival than those with less tumor reduction by 6 mo. Additionally, patients who had more severe disease (as per the International Metastatic Renal Cell Carcinoma Database Consortium) at the start of study treatment survived for longer without disease progression with lenvatinib plus pembrolizumab than with sunitinib.

BACKGROUND: In the primary analysis of the CLEAR study, lenvatinib plus pembrolizumab significantly improved progression-free survival and overall survival versus sunitinib in patients with advanced renal cell carcinoma (data cutoff Aug 28, 2020). We aimed to assess overall survival based on 7 months of additional follow-up. METHODS: This is a protocol-prespecified updated overall survival analysis (data cutoff March 31, 2021) of the open-label, phase 3, randomised CLEAR trial. Patients with clear-cell advanced renal cell carcinoma who had not received any systemic anticancer therapy for renal cell carcinoma, including anti-vascular endothelial growth factor therapy, or any systemic investigational anticancer drug, were eligible for inclusion from 200 sites (hospitals and cancer centres) across 20 countries. Patients were randomly assigned (1:1:1) to receive lenvatinib (20 mg per day orally in 21-day cycles) plus pembrolizumab (200 mg intravenously every 21 days; lenvatinib plus pembrolizumab group), lenvatinib (18 mg per day orally) plus everolimus (5 mg per day orally; lenvatinib plus everolimus group [not reported in this updated analysis]) in 21-day cycles, or sunitinib (50 mg per day orally, 4 weeks on and 2 weeks off; sunitinib group). Eligible patients were at least 18 years old with a Karnofsky performance status of 70 or higher. A computer-generated randomisation scheme was used, and stratification factors were geographical region and Memorial Sloan Kettering Cancer Center prognostic groups. The primary endpoint was progression-free survival assessed by independent imaging review according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1). In this Article, extended follow-up analyses for progression-free survival and protocol-specified updated overall survival data are reported for the intention-to-treat population. No safety analyses were done at this follow-up. This study is closed to new participants and is registered with ClinicalTrials.gov, NCT02811861. FINDINGS: Between Oct 13, 2016, and July 24, 2019, 1417 patients were screened for inclusion in the CLEAR trial, of whom 1069 (75%; 273 [26%] female, 796 [74%] male; median age 62 years [IQR 55-69]) were randomly assigned: 355 (33%) patients (255 [72%] male and 100 [28%] female) to the lenvatinib plus pembrolizumab group, 357 (33%) patients (275 [77%] male and 82 [23%] female) to the sunitinib group, and 357 (33%) patients to the lenvatinib plus everolimus group (not reported in this updated analysis). Median follow-up for progression-free survival was 27·8 months (IQR 20·3-33·8) in the lenvatinib plus pembrolizumab group and 19·4 months (5·5-32·5) in the sunitinib group. Median progression-free survival was 23·3 months (95% CI 20·8-27·7) in the lenvatinib plus pembrolizumab group and 9·2 months (6·0-11·0) in the sunitinib group (stratified hazard ratio [HR] 0·42 [95% CI 0·34-0·52]). Median overall survival follow-up was 33·7 months (IQR 27·4-36·9) in the lenvatinib plus pembrolizumab group and 33·4 months (26·7-36·8) in the sunitinib group. Overall survival was improved with lenvatinib plus pembrolizumab (median not reached [95% CI 41·5-not estimable]) versus sunitinib (median not reached [38·4-not estimable]; HR 0·72 [95% CI 0·55-0·93]). INTERPRETATION: Efficacy benefits of lenvatinib plus pembrolizumab over sunitinib were durable and clinically meaningful with extended follow-up. These results support the use of lenvatinib plus pembrolizumab as a first-line therapy for patients with advanced renal cell carcinoma. FUNDING: Eisai and Merck Sharp & Dohme.

BACKGROUND: In the phase 3 KEYNOTE-426 (NCT02853331) trial, pembrolizumab + axitinib demonstrated improvement in overall survival, progression-free survival, and objective response rate over sunitinib monotherapy for advanced renal cell carcinoma (RCC). OBJECTIVE: To evaluate health-related quality of life (HRQoL) in KEYNOTE-426. DESIGN, SETTING, AND PARTICIPANTS: A total of 861 patients were randomly assigned to receive pembrolizumab + axitinib (n = 432) or sunitinib (n = 429). HRQoL data were available for 429 patients treated with pembrolizumab + axitinib and 423 patients treated with sunitinib. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: HRQoL end points were measured using the European Organisation for the Research and Treatment of Cancer Core (EORTC) Quality of Life Questionnaire (QLQ-C30), EQ-5D visual analog rating scale (VAS), and Functional Assessment of Cancer Therapy Kidney Cancer Symptom Index-Disease-Related Symptoms (FKSI-DRS) questionnaires. RESULTS AND LIMITATIONS: Better or not different overall improvement rates from baseline between pembrolizumab + axitinib and sunitinib were observed for the FKSI-DRS (-0.79% improvement vs sunitinib; 95% confidence interval [CI] -7.2 to 5.6), QLQ-C30 (7.5% improvement vs sunitinib; 95% CI 1.0-14), and EQ-5D VAS (9.9% improvement vs sunitinib; 95% CI 3.2-17). For time to confirmed deterioration (TTcD) and time to first deterioration (TTfD), no differences were observed between arms for the QLQ-C30 (TTcD hazard ratio [HR] 1.0; 95% CI 0.82-1.3; TTfD HR 0.82; 95% CI 0.69-0.97) and EQ-5D VAS (TTcD HR 1.1; 95% CI 0.87-1.3; TTfD HR 0.98; 95% CI 0.83-1.2). TTfD was not different between treatment arms (HR 1.1; 95% CI 0.95-1.3) for the FKSI-DRS, but TTcD favored sunitinib (HR 1.4; 95% CI 1.1-1.7). Patients were assessed during the off-treatment period for sunitinib, which may have underestimated the negative impact of sunitinib on HRQoL. CONCLUSIONS: Overall, patient-reported outcome scales showed that results between the pembrolizumab + axitinib and sunitinib arms were not different, with the exception of TTcD by the FKSI-DRS. PATIENT SUMMARY: Compared with sunitinib, pembrolizumab + axitinib delays disease progression and extends survival, while HRQoL outcomes were not different between groups.

Sunitinib is a broad-spectrum multitargeted tyrosine kinase inhibitor mainly used as second-line therapy for non-resectable gastrointestinal stromal or first-line treatment option of metastatic renal cell carcinoma (mRCC), and as an "off-label" option in pediatric oncology. It has been previously reported that sunitinib elevates the mean corpuscular volume of erythrocytes (MCV) in treated subjects. The aim of this study was to assess time-dependent changes of this effect and evaluate its possible clinical relevance. In this study, 179 adult and 21 pediatric patients with solid tumors treated with sunitinib were retrospectively analyzed. The laboratory and treatment-related data were collected for each treatment period. The regression model with a broken-line relationship was used to fit time dependence of the MCV. In the adult group, the MCV was increasing during the first 21.6 weeks (median) of treatment in a median level of 99.8 fL, where it stabilized. MCV increase was faster in the patients who suffered from treatment-related adverse events (21.3 vs. 24.6 weeks, p = 0.010). In the pediatric cohort, the MCV dynamics were similar to adults. In conclusion, MCV changes during sunitinib treatment in pediatric and adult patients may be of clinical utility in monitoring sunitinib treatment course.
