BackgroundImmune-checkpoint-inhibitors (ICIs) have become the cornerstone of metastatic renal-cell-carcinoma (mRCC) therapy. However, data are limited regarding clinical outcomes by race. In this study, we compared the real-world outcomes between African American (AA) and Caucasian mRCC patients treated with ICIs.MethodsWe performed a retrospective study of 198 patients with mRCC who received ICI at the Emory Winship Cancer Institute from 2015-2020. Clinical outcomes were measured by overall survival (OS), progression-free survival (PFS), and overall response rate (ORR) defined as a complete or partial response maintained for at least 6 months per response evaluation criteria in solid tumors version 1.1. Univariate and multivariable analyses were carried out for OS and PFS by Cox proportional-hazard model and ORR by logistical-regression model. Descriptive statistics compared rates of immune-related adverse events (irAEs) and non-clear-cell-RCC (nccRCC) histology were assessed using Chi-square test.ResultsOur cohort was comprised of 38 AA and 160 Caucasian patients. Most were diagnosed with clear-cell-RCC (ccRCC) (78%) and more than half received (57%) PD-1/PD-L1 monotherapy. Most patients were intermediate or poor-risk groups (83%). Comparing to Caucasians, our AA cohort contained more females and nccRCC cases. Kaplan-Meier method showed AAs had no statistically different median OS (17 vs 25 months, p=0.368) and PFS (3.1 vs 4.4 months, p=0.068) relative to Caucasian patients. On multivariable analysis, AA patients had significantly shorter PFS (HR=1.52, 95% CI: 1.01-2.3, p=0.045), similar ORR (OR=1.04, 95% CI: 0.42-2.57, p=0.936) and comparable OS (HR=1.09, 95% CI: 0.61-1.95, p=0.778) relative to Caucasians.ConclusionsOur real-world analysis of ICI-treated mRCC patients showed that AAs experienced shorter PFS but similar OS relative to Caucasians. This similarity in survival outcomes is reassuring for the use of ICI amongst real-world patient populations, however, the difference in treatment response is poorly represented in early outcomes data from clinical trials. Thus, the literature requires larger prospective studies to validate these findings.

293 Background: Checkpoint inhibitors (CPIs) are a treatment option for patients with metastatic renal cell carcinoma (mRCC), but there is limited clinical data on the efficacy of targeted therapies following CPI treatment. Cabozantinib is a tyrosine kinase inhibitor (TKI) that targets multiple receptor kinases implicated in tumorigenesis. In the US, cabozantinib is approved for use in patients with advanced RCC including after CPI treatment. Methods: This retrospective observational cohort study (NCT04353765) evaluated outcomes associated with cabozantinib or other TKIs (axitinib, lenvatinib, pazopanib, sorafenib, sunitinib) in patients with mRCC following CPI treatment. Eligible patients initiated TKI therapy between May 1, 2016 and Sep 31, 2019 and had received a CPI as their last systemic treatment prior to TKI therapy. Patients were identified from the US Oncology Network iKnowMed electronic health record database through structured queries and a targeted chart review. The following real-world outcomes were assessed: 6-month response rate (RR6months; primary); overall response rate (ORR); overall survival (OS); time to treatment discontinuation (TTD); rates of dose reductions, and discontinuation due to adverse events (AEs). The p value for RR6months was used to test for non-inferiority. Results: Eligible patients ( n = 247) had a mean (SD) age of 65.9 (10.5) years and 74.1% were male; 75.7% ( n = 187) received cabozantinib and 24.3% ( n = 60) received other TKIs. All patients had intermediate or poor MSKCC score; more poor-risk patients received cabozantinib than other TKIs (28.9% vs 20%). Outcomes data are shown in the Table. Compared with other TKIs, cabozantinib was associated with a significantly higher RR6months and ORR, and TTD was twice as long with cabozantinib. Discontinuation due to AEs was more frequent with other TKIs than with cabozantinib, although this was not statistically significant; 21.7% of discontinuations occurred during the first 3 months of treatment. AEs leading to discontinuation were consistent with the known safety profile of the products. Conclusions: In this mRCC population receiving routine care in the US, cabozantinib was used more frequently than other TKIs after CPI treatment. Cabozantinib was an effective and well tolerated option post-CPI, with a high response rate in the real-world setting.abozantinib was associated with a significantly higher response rate and a lower discontinuation rate due to AEs; TTD was double that of other TKIs.

341 Background: Neutrophilia is known to be associated with worse prognosis in metastatic renal cell carcinoma (mRCC); however, less is known about the role of eosinophils in the response to immunotherapy (IO). We investigated the association of the baseline neutrophil to eosinophil ratio (NER) with outcomes to IO-based combination treatment in mRCC. Methods: Patients with mRCC treated with ipilimumab plus nivolumab, pembrolizumab plus axitinib, or avelumab plus axitinib at the Vanderbilt-Ingram Cancer Center were retrospectively identified. Patients on >10mg prednisone and patients with prior IO were excluded. Baseline NER (at time of first IO) and association with progression free survival (PFS), overall survival (OS), and objective response rate (ORR) were investigated. Data cutoff was 9/1/2020. Analysis for PFS and OS was performed using the log-rank test and Mantel-Haenszel method, and analysis of the odds ratio for ORR was performed using Fischer’s exact test. Results: Sixty-one patients were identified: 89% clear cell histology, 74% prior nephrectomy, 69% IMDC intermediate risk, and 72% treatment-naïve. Patients with baseline NER < median (N=31) had improved clinical outcomes compared to patients with baseline NER > median (N=30) (Table). Improvement in PFS by NER was maintained when stratified by anti-PD-1/CTLA-4 and anti-PD(L)-1/VEGF (p= 0.0062 and p= 0.049); however, differences in OS and ORR were no longer significant. The median baseline NER among patients with partial response (PR) was significantly lower at 22.7 (95% CI 18.9-31.1) vs. 51.6 (95% CI 39.5-93.1) among those with progressive disease (PD) (p= 0.0054). For comparison, the median neutrophil to lymphocyte ratio was not significantly different between PR (2.60) and PD (3.84, p= 0.056). Conclusions: Patients with a low baseline NER treated with IO-based combinations had improved clinical outcomes compared to patients with a high baseline NER. Additional investigation of this parameter in larger cohorts is warranted. [Table: see text]

Molecular Targeted Agents

The management of metastatic renal cell carcinoma (mRCC) has evolved considerably in the last decade. A number of different systemic molecular targeted agents that have been recently approved have improved the survival of patients with mRCC. This mini-review focuses on the implementation of multi-modality therapy in the management of mRCC and the approved indications of the various available novel agents. These novel agents have expanded our armamentarium and improved clinical outcomes of this challenging disease that has considerable biological heterogeneity and clinical variability.
