441^ Background: Previous studies have shown minimal impact of tyrosine kinase inhibitors on primary renal tumors. In this phase II trial, we investigate the safety and role of the axitinib in downsizing tumors in patients with non-metastatic clear cell renal cell carcinoma (RCC) prior to surgical resection. Methods: Patients with clinical stage T2-T3b N0 M0 biopsy-proven RCC were eligible for this study. Patients received axitinib daily for 12 weeks prior to surgery. The primary outcome was objective response rate. Secondary outcomes included safety, tolerability, feasibility of administration of axitinib and quality of life (using FKSI-15). A dedicated radiologist independently reviewed all CT scans to evaluate for response using RECIST. Results: Twenty-four patients were treated between 2011 and 2013. All patients had biopsy-proven clear cell RCC. Twenty-three patients continued axitinib for 12 weeks, and underwent surgery as planned without delay. One patient stopped treatment before 12 weeks due to adverse events (AEs) and was taken to surgery early. Median reduction of primary renal tumor size was 28.3% (range 5.3-42.9%). Eleven patients (45.8%) experienced a partial response by RECIST, and 13 patients had stable disease. There was no progression of disease while on axitinib. The most common AEs were hypertension, fatigue, oral mucositis, hypothyroidism, and hand-foot syndrome. No grade 4 AEs were observed. Intraoperatively, no complications or unusual bleeding were encountered. Postoperatively, 2 grade 3 and 13 grade 2 complications were noted, while no grade 4 or 5 complications occurred. FKSI-15 did change over time (p < 0.0001), with quality of life worsening in comparison to the screening assessment by week 7 (p = 0.0004). However, by week 19, quality of life was not found to be statistically different from screening (p = 0.3344). Conclusions: Axitinib was clinically active and well tolerated in the neoadjuvant setting in patients with locally advanced non-metastatic ccRCC. Clinical trial information: NCT01263769.

4516 Background: Previous studies have shown minimal impact of TKIs on primary renal tumor downsizing. Axitinib is a VEGFR TKI that has been recently approved for use in patients with metastatic clear cell renal cell carcinoma (RCC). In this prospective phase II trial, we sought to investigate the safety and role of axitinib in downsizing tumors in patients with non-metastatic renal cell carcinoma, prior to undergoing surgical resection. Methods: Patients with locally advanced (clinical stage T2-T3b N0 M0) biopsy-proven clear cell RCC were eligible for this phase II clinical trial. The primary outcome was objective response rate (using RECIST) following the administration of axitinib for 12 weeks prior to undergoing radical nephrectomy. Secondary outcomes included safety, tolerability, and feasibility of administration of axitinib in this patient population. Patients were given axitinib 5mg PO BID, and dose titration was allowed. Axitinib was continued until 36 hours prior to surgery. A dedicated radiologist independently reviewed all CT scans to evaluate for response using RECIST. Results: The study goal of enrolling 24 patients has been recently reached. At present, nineteen patients have completed the studies required for assessment of the primary outcome and are hereby reported. Fifteen patients were males, and four were females. Median age was 61 years (range 42-83 years). All patients had biopsy-proven clear cell RCC. All 19 patients continued axitinib for 12 weeks, and underwent surgery as planned without delay. Adverse events of any grade were: arthralgia in 6, hypothyroidism in 14, fatigue in 15, and hypertension in 16 patients. No wound complications occurred after surgery. Nine patients (47%) experienced a partial response by RECIST, and 10 patients had stable disease. There was no progression of disease while on axitinib. Conclusions: Axitinib is well tolerated in the neoadjuvant setting in patients with planned surgery for locally advanced non-metastatic clear cell RCC. The drug showed tumor downsizing activity when given for 12 weeks prior to surgery. Adverse events of any grade were common and easily manageable with routine care. Clinical trial information: NCT01263769.

Purpose The decreased effectiveness of single-agent targeted therapies in advanced non–clear cell renal cell carcinoma (ncRCC) compared with clear cell renal cell carcinoma (RCC) supports the study of combination regimens. We evaluated the efficacy of everolimus plus bevacizumab in patients with metastatic ncRCC. Patients and Methods In this single-center phase II trial, treatment-naive patients received everolimus 10 mg oral once per day plus bevacizumab 10 mg/kg intravenously every 2 weeks. The primary end point was progression-free survival (PFS) at 6 months. Correlative analyses explored candidate tissue biomarkers through next-generation sequencing. Results Thirty-five patients were enrolled with the following histologic subtypes: chromophobe (n = 5), papillary (n = 5), and medullary (n = 2) RCC and unclassified RCC (uRCC, n = 23). The majority of patients had papillary growth as a major component (n = 14). For 34 evaluable patients, median PFS, overall survival, and objective response rate (ORR) were 11.0 months, 18.5 months, and 29%, respectively. PFS varied by histology ( P < .001), and ORR was higher in patients with significant papillary (seven of 18) or chromophobe (two of five) elements than for others (one of 11). Presence of papillary features were associated with benefit, including uRCC, where it correlated with ORR (43% v 11%), median PFS (12.9 v 1.9 months), and overall survival (28.2 v 9.3 months; P < .001). Several genetic alterations seemed to segregate by histology. In particular, somatic mutations in ARID1A were seen in five of 14 patients with papillary features but not in other RCC variants. All five patients achieved treatment benefit. Conclusion The study suggests efficacy for this combination in patients with ncRCC characterized by papillary features. Distinct mutational profiles among ncRCCs vary according to specific histology.
