PURPOSE COSMIC-021 is evaluating cabozantinib plus atezolizumab in patients with solid tumors. We report results from patients with advanced clear cell (cc) and non–clear cell (ncc) renal cell carcinoma (RCC). METHODS This phase Ib study ( NCT03170960 ) enrolled patients age ≥ 18 years with advanced RCC. A dose-escalation stage was followed by expansion cohorts. For cohort expansion, prior systemic therapy was not permitted for ccRCC but allowed for nccRCC. Patients received oral cabozantinib 40 mg once a day (ccRCC and nccRCC) or 60 mg once a day (ccRCC only) plus atezolizumab (1,200 mg intravenously, once every 3 weeks). The primary end point was investigator-assessed objective response rate (ORR) per RECIST v1.1; the secondary end point was safety. RESULTS A total of 102 patients were enrolled. Median follow-up was 25.8, 15.3, and 13.3 months for the 40-mg ccRCC, 60-mg ccRCC, and nccRCC groups, respectively. ORR was 53% (80% CI, 41 to 65) in the 40-mg ccRCC group (n = 34) and 58% (80% CI, 46 to 70) in the 60-mg ccRCC group (n = 36), 3% and 11%, respectively, with complete response; median progression-free survival (exploratory end point) was 19.5 and 15.1 months, respectively. In nccRCC (n = 32), ORR was 31% (80% CI, 20 to 44), all partial responses; median progression-free survival was 9.5 months. Grade 3 or 4 treatment-related adverse events (TRAEs) were reported by 71% of patients in the 40-mg ccRCC group, 67% in the 60-mg ccRCC group, and 38% in the nccRCC group; TRAEs leading to discontinuation of both agents occurred in 15%, 6%, and 3% of patients, respectively. There were no grade 5 TRAEs. CONCLUSION The novel combination of cabozantinib plus atezolizumab demonstrated encouraging clinical activity and acceptable tolerability in patients with advanced ccRCC and nccRCC. Disease control was observed across dose levels and histologic subtypes.

Abstract Purpose Combined immunotherapy of nivolumab plus ipilimumab for intermediate- and poor-risk metastatic clear cell renal cell carcinoma showed prolonged progression-free survival and high objective response rate in a randomized phase III clinical trial. However, the efficacy of this treatment for papillary renal cell carcinoma remains unclear. In the present study, we analysed the efficacy of nivolumab plus ipilimumab therapy for papillary renal cell carcinoma compared with that for clear cell renal cell carcinoma. Materials and Methods This is a retrospective study of 30 patients with metastatic renal cell carcinoma who received nivolumab and ipilimumab as first-line therapy between December 2015 and May 2020. The objective response rate, progression-free survival and toxicity were compared between the two groups (clear cell renal cell carcinoma and papillary renal cell carcinoma). Results Out of 30 patients, 7 and 23 were diagnosed with papillary renal cell carcinoma and clear cell renal cell carcinoma, respectively. With a median follow-up of 7.2 months, the median progression-free survival was significantly shorter in papillary renal cell carcinoma than in clear cell renal cell carcinoma (2.4 vs. 28.1 months, P = 0.014). Of the seven patients with papillary renal cell carcinoma, one had partial response, one had stable disease and five had progressive disease, resulting in an objective response rate of 14.2%, which was lower compared to that of clear cell renal cell carcinoma (14.2 vs. 52.1%, P = 0.06). Discontinuation due to toxicity was not observed with papillary renal cell carcinoma, meanwhile 60.8% of patient with clear cell renal cell carcinoma discontinued treatment due to toxicity. Conclusion Nivolumab plus ipilimumab had modest efficacy for papillary renal cell carcinoma compared with that for clear cell renal cell carcinoma. Nivolumab plus ipilimumab remains an option for a limited number of patients with intermediate- or poor-risk papillary renal cell carcinoma.

Introduction: Limited data exists on utilization of protein post-translational modifications as biomarkers for clear cell renal cell carcinoma (ccRCC). We employed high-throughput glycoproteomics to evaluate differential expression of glycoprotein-isoforms as novel markers for ccRCC progression-free survival (PFS). Methods: Plasma samples were obtained from 77 patients treated surgically for ccRCC. Glycoproteomic analyses were carried out after liquid chromatography tandem mass spectrometry. Age-adjusted Cox proportional hazard models were constructed to evaluate PFS. Optimized Harrells c-index was employed to dichotomize the collective for the construction of Kaplan-Meier curves. Results: The average length of follow-up was 3.4 (range: 0.04-9.83) years. Glycoproteomic analysis identified 39 glycopeptides and 14 non-glycosylated peptides that showed statistically significant (false discovery rate p ≤0.05) differential expression associated with PFS. Five of the glycosylated peptides conferred continuous hazard ratio of > 6 (range 6.3-11.6). These included prothrombin A2G2S glycan motif (HR=6.47, P=9.53E-05), immunoglobulin J chain FA2G2S2 motif (HR=10.69, P=0.001), clusterin A2G2 motif (HR=7.38, P=0.002), complement component C8A A2G2S2 motif (HR=11.59, P=0.002), and apolipoprotein M glycopeptide with non-fucosylated and non-sialylated hybrid-type glycan (HR=6.30, P=0.003). Kaplan-Meier curves based on dichotomous expression of these five glycopeptides resulted in hazard ratios of 3.9-10.7, all with p-value < 0.03. Kaplan-Meyer plot using the multivariable model comprising 3 of the markers yielded HR of 11.96 (p <0.0001). Conclusion: Differential glyco-isoform abundance of plasma proteins may be a useful source of biomarkers for the clinical course and prognosis of ccRCC.

TPS4590 Background: Currently no level 1 evidence exists to guide therapeutic decisions in patients with metastatic non-clear cell renal cell carcinoma. Case series and retrospective analyses suggest that strategies targeting either the VEGF or mTOR/TORC1 pathways have clinical activity in papillary, chromophobe, or poorly differentiated histologic subtypes. Methods: We are conducting an international, randomized phase 2 trial of patients with metastatic non-clear cell RCC; either papillary, chromophobe, or undifferentiated histology; any Motzer risk group; and who have had no prior systemic therapy. All patients contribute tissue to an international biorepository for correlative genomic, genetic, and protein biomarker studies, along with companion longitudinal plasma and urine angiome studies. Patients are randomized to either everolimus or sunitinib (1:1) at FDA approved dosing until progression. The primary endpoint is progression free survival. Trial status: Seventy-three out of a planned 108 subjects have been enrolled at the time of abstract submission: median age 64, 59 white, 10 black, 4 unknown race, and includes 42 papillary and 31 chromophobe/undifferentiated histologies, 49 men and 22 women. Accrual is anticipated to be completed by December 2013. Accrual distribution by country is currently 43 (USA), 27 (UK), and 3 (Canada). The first DSMB meeting was conducted after 40 subjects completed at least 6 months of therapy and concluded that there were no unexpected safety signals and that the study should proceed. Tissue (primary, some metastatic, urine, plasma, whole blood) has been collected on all patients to date through the Duke Center for Human Genetics Biorepository. Clinical trial information: NCT01108445.

Purpose. Grade-dependent decrease of lipid storage in clear cell renal cell carcinoma (ccRCC) leads to morphology changes in HE sections. This study investigated the role of cytoplasmic features in frozen sections of ccRCC on prognosis using the digital pathology approach. Methods. We established an automatic pipeline that performed tumor region selection, stain vector normalization, nuclei segmentation, and feature extraction based on the pathologic data from Shanghai General Hospital and The Cancer Genome Atlas database. Extracted features were subjected to survival analysis. Results. Kurtosis of the cytoplasm in the hematoxylin channel was correlated with progression-free survival (HR 0.10, 95% CI: 0.04–0.24, p = 6.52 ∗ 10 − 7 ) and overall survival (HR 0.11, 95% CI: 0.05–0.31, p = 1.72 ∗ 10 − 5 ) in ccRCC, which outperformed other texture features in this analysis. Multivariate Cox regression analysis revealed that low kurtosis of cytoplasm in the hematoxylin channel was an independent predictor for a shorter progression-free survival time ( p = 0.044 ) and overall survival time (p = 0.01). Kaplan–Meier survival analysis of progression-free survival and overall survival also showed a significantly worse prognosis in patients with low kurtosis of the cytoplasm in the hematoxylin channel (both p < 0.0001 ). Lower kurtosis of cytoplasm in the hematoxylin channel was associated with higher pathologic grade, less cholesterol ester, and more mitochondrial DNA content. Conclusion. Kurtosis of the cytoplasm in the hematoxylin channel predicts survival in clear cell renal cell carcinoma.

e17077 Background: Sequential inhibition of the vascular endothelial growth factor (VEGF) pathway with sorafenib could be useful for patients with advanced or metastatic renal cell carcinoma (RCC). Our aim was to determine the activity and tolerability of sorafenib as a 2nd-line therapy in advanced RCC initially treated with a different VEGF-tyrosine kinase inhibitor (TKI). Methods: Prospective observational cohort in Mexico City (July 2012 to July 2019). We included 148 subjects with metastatic RCC, treated by nephrectomy and who had RCC progression despite treatment with sunitinib (n = 144) or pazopanib (n = 4). All patients received sorafenib 400 mg orally twice a day on a continuous dosing schedule until disease progression or intolerable toxicity. The primary endpoint was time to progression evaluated every 12-16 weeks. Risk factors were classified according to the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC-RF) prognostic model. Results: Mean age of cohort was 58±10 years, 104 (70%) were male, 51 (35%) had none of IMDC-risk factors, and the most common sites of metastasis before sorafenib treatment were lung (n = 79, 53%) and bone (n = 30, 20%). The median progression-free survival and survival after the introduction of sorafenib treatment was 8.5 months (95% IC 6.8-10.2) and 40.1 months (95% IC 35.2-45.0) respectively. Median overall survival from RCC diagnosis to death was 71 months (95% CI 63.9-79.4). Median progression-free survival was longer in advanced RCC with none IMDC-RF compared with subjects with ≥2 IMDC-RF (10.3 [95%CI 6.1-14.6] vs 7.9 [95%CI 5.8-9.9] mo. respectively, p = 0.035). Age > 65 decreased risk of progression after sorafenib therapy (OR 0.33, 95% CI 0.14-0.77, p = 0.010). Median progression-free survival in subjects > 65 yrs old was longer (14 months, 95% CI 9.2-17.9) compared to subjects ≤65 yrs (7.2 months, 95% CI 5.5-8.9, p = 0.018). Adverse events associated to sorafenib occurred in 118 (80%) subjects: hand-foot syndrome (n = 118, 80%), diarrhea (n = 113, 76%), hypothyroidism (41, 28%), and mucositis (84, 57%). Any adverse events corresponding to a grade > 2 occurred in 48 (32%) patients. Conclusions: Sequential inhibition of VEGF with sorafenib as a 2nd-line treatment may benefit patients with metastatic RCC, especially in subjects > 65 yrs old. Further clinical trials are needed.

Objective: We aimed to evaluate the role of intra-tumoral CXCR1 expression in predicting prognosis and treatment response in metastatic clear-cell renal cell carcinoma patients receiving tyrosine kinase inhibitors. Materials and methods: Patients with metastatic clear-cell renal cell carcinoma presented between February 2018–December 2019 were studied for the CXCR1 expression in tumor tissues before starting tyrosine kinase inhibitors. Primary outcome measure was progression-free survival. Secondary outcome measures included overall survival and prediction of treatment response. Results: The study included 35 patients with a mean age of 53.6±9.6 years. At a mean follow-up of 12.2±4.1 months, 17 (48.6%) patients had disease progression including eight (22.9%) deaths. Patients with high CXCR1 expression, compared to those with low CXCR1 expression, had a significantly shorter 12-month progression-free survival (35.4% vs 77.9%, p=0.01) and an insignificant impact on 12-month overall survival. The CXCR1 expression scores significantly differed between patients with progressive and nonprogressive disease (20.1 vs 15.1, p=0.01) and patients with high CXCR1 expression had a reduced benefit from tyrosine kinase inhibitors. The multivariate Cox regression analysis showed CXCR1 expression as a significant predictor of progression-free survival. Conclusion: High intra-tumoral CXCR1 expression before tyrosine kinase inhibitors can be an independent prognostic factor for progression-free survival and predictor of reduced benefit in patients with metastatic clear-cell renal cell carcinoma. Level of evidence: Level 2b.

Sarcomatoid Renal Cell Carcinoma

Background: Combinations based on immune checkpoint inhibitors are the new first-line standard treatment for metastatic renal cell carcinoma. Sarcomatoid renal cell carcinoma (sRCC) has a dismal prognosis but good immunogenicity. Methods: The authors performed a network meta-analysis of Phase III randomized trials of immune checkpoint inhibitor-based combinations versus standard tyrosine kinase inhibitor monotherapy reporting data for sRCC. The endpoints were overall survival, progression-free survival and objective response rate. Results: Five trials comprising 569 sRCC patients (out of a total of 4409 metastatic renal cell carcinoma patients) were included. Nivolumab–cabozantinib was the highest ranking treatment for overall survival (p-value = 88%) and progression-free survival (p-value = 81%). Atezolizumab–bevacizumab had the highest rank for objective response rate (p-value = 80%). Conclusion: Despite some limitations, nivolumab–cabozantinib might be the preferred first-line option for sRCC in terms of efficacy.

Purpose Trebananib, an investigational recombinant peptide-Fc fusion protein, neutralizes the receptor-ligand interaction between Tie2 and angiopoietin-1/2. This phase II study was conducted to evaluate trebananib plus sunitinib, a vascular endothelial growth factor receptor inhibitor, in patients with metastatic clear cell renal cell carcinoma. Patients and Methods Adults with metastatic renal cell carcinoma were enrolled sequentially onto two cohorts that received sunitinib 50 mg once per day for 4 weeks on and 2 weeks off and intravenous trebananib once per week at a dose of 10 mg/kg in cohort A or 15 mg/kg in cohort B. The primary end points were incidences of adverse events (AEs) and dose interruptions of sunitinib during the first 12 weeks of treatment. Secondary end points included objective response rate and progression-free survival. Results Eighty-five patients were enrolled: 43 in cohort A, and 42 in cohort B. During the first 12 weeks of treatment, 58% and 57% of patients in cohorts A and B, respectively, had sunitinib dose interruptions (dose decrease, withholding, or withdrawal). The most frequent AEs were diarrhea (cohort A, 74%; cohort B, 67%), mucosal inflammation (cohort A, 49%; cohort B, 60%), and hypertension (cohort A, 52%; cohort B, 45%). AEs of grade 3 or greater occurred in 58% of patients in cohort A and in 69% of patients in cohort B. The objective response rate was 58% and 63% in cohorts A and B, respectively. The median progression-free survival time was 13.9 months (95% CI, 10.4 to 19.2) and 16.3 months (95% CI, 13.1 to 21.4) in cohorts A and B, respectively. The median overall survival time was 36 months (95% CI, 25.2 to not estimable) in cohort A and was not estimable (median follow-up, 25 months) in cohort B. Conclusion Trebananib plus sunitinib seemed to increase toxicity at the tested doses. Efficacy results suggest a potential benefit for the addition of trebananib to sunitinib.
