Everolimus in metastatic renal cell carcinoma patients intolerant to previous VEGFr-TKI therapy: a RECORD-1 subgroup analysis.

ABSTRACT: A relevant percentage of patients with metastatic renal cell carcinoma develop intolerance to vascular endothelial growth factor receptor-tyrosine kinase inhibitors (VEGFr-TKIs) and require careful selection of subsequent treatment. This retrospective analysis evaluated the safety and efficacy of everolimus in patients enrolled in the phase-III RECORD-1 trial who discontinued previous VEGFr-TKI therapy because of toxicity.Patients with an adverse event (AE) as their primary reason for discontinuation of previous VEGFr-TKI therapy were included. Median progression-free survival (PFS) for VEGFr-TKI-intolerant patients in each arm was estimated using the Kaplan-Meier method, and effect on PFS (hazard ratio (HR)) was calculated using the Cox proportional hazard model.In VEGFr-TKI-intolerant patients (n=58, 14%), median PFS was 5.4 months with everolimus and 1.9 months with placebo (HR: 0.32; P=0.004). In sunitinib-intolerant patients (n=26), median PFS was 5.1 months with everolimus and 2.8 months with placebo (HR: 0.28; P=0.033). Grade 3/4 AEs reported with everolimus in VEGFr-TKI-intolerant patients included infections (16%), fatigue (7%) and stomatitis (4%). The toxicity profile of everolimus was similar in the VEGFr-TKI-intolerant and overall study populations.Everolimus is well tolerated and efficacious with no increased toxicity in patients intolerant to VEGFr-TKI therapy.

Project description:BackgroundHyperglycemia and hypercholesterolemia are class effects of mammalian target of rapamycin inhibitors. The purpose of this study was to characterize safety and efficacy of patients with metastatic renal cell carcinoma (mRCC) treated with everolimus in RECORD-1 (REnal Cell cancer treatment with Oral RAD001 given Daily) and REACT (RAD001 Expanded Access Clinical Trial in RCC) who developed these events.Patients and methodsAdults with vascular endothelial growth factor-refractory mRCC received everolimus 10 mg/d in the randomized RECORD-1 (n = 277) and open-label REACT (n = 1367) studies. Outcomes included safety, treatment duration, overall response, and progression-free survival for patients who developed hypercholesterolemia or hyperglycemia.ResultsIn RECORD-1, 12% (33 of 277) and 20% (55 of 277) of patients developed any grade hyperglycemia or hypercholesterolemia, respectively, with only 6% (78 of 1367) and 1% (14 of 1367) of the same events, respectively, in REACT. Median everolimus treatment duration was similar for patients with hyperglycemia or hypercholesterolemia (RECORD-1, 6.2 and 6.2 months, respectively; REACT, 4.4 and 4.5 months, respectively), but longer than the overall populations (RECORD-1, 4.6 months; REACT, 3.2 months). In RECORD-1/REACT, 82%/68% of patients with hyperglycemia and 75%/71% of patients with hypercholesterolemia achieved partial response or stable disease. The incidence of clinically notable Grade 3 or 4 adverse events, other than anemia and lymphopenia, appeared to be similar across trials and subgroups. Although there was a trend for improved progression-free survival with development of hyperglycemia or hypercholesterolemia, the association was not statistically significant.ConclusionHyperglycemia and hypercholesterolemia were observed in low numbers of patients, and although these events might be associated with improved response to everolimus, the differences were not significant. These findings should be validated with prospective biomarker studies.

Project description:BACKGROUND:RECORD-1 demonstrated clinical benefit of everolimus in patients with metastatic renal cell carcinoma (mRCC) previously treated with sunitinib, sorafenib, or both; prior treatment with cytokines, bevacizumab, and chemotherapy was also permitted. RECORD-4 prospectively assessed everolimus in a purely second-line setting. METHODS:Patients with clear-cell mRCC were enrolled into one of three cohorts based on first-line therapy with sunitinib, other anti-VEGF agents, or cytokines. Patients were treated with everolimus 10 mg/day until progression (RECIST, v1.0) or intolerance. The primary end point was progression-free survival (PFS) per investigator review. Data cutoff was 1 September 2014, for the primary analysis and 26 June 2015, for the final overall survival (OS) analysis. RESULTS:Enrolled patients (N = 134) previously received sunitinib (n = 58), other anti-VEGF therapy (n = 62; sorafenib, 23; bevacizumab, 16; pazopanib, 13; tivozanib, 5; and axitinib, 3), or cytokines (n = 14). Overall median age was 59 years, and most patients were men (68%) and of favorable/intermediate MSKCC risk (52/37%). Overall median PFS was 7.8 months [95% confidence interval (CI) 5.7-11.0]; in the cohorts, it was 5.7 months (95% CI 3.7-11.3) with previous sunitinib, 7.8 months (95% CI 5.7-11.0) with other previous anti-VEGF therapy, and 12.9 months [95% CI 2.6-not estimable (NE)] with previous cytokines. Overall, 67% of patients achieved stable disease as their best objective response. At final OS analysis, total median OS was 23.8 months (95% CI 17.0-NE) and, in the cohorts, it was 23.8 months (95% CI 13.7-NE) with previous sunitinib, 17.2 months (95% CI 11.9-NE) with other previous anti-VEGF therapy, and NE (95% CI 15.9-NE) with previous cytokine-based therapy. Overall, 56% of patients experienced grade 3 or 4 adverse events (regardless of relationship to study drug). CONCLUSIONS:These results confirm the PFS benefit of second-line everolimus after first-line sunitinib or other anti-VEGF therapies. The safety profile of everolimus was consistent with previous experience. CLINICAL TRIAL NAME AND IDENTIFIER:Everolimus as Second-line Therapy in Metastatic Renal Cell Carcinoma (RECORD-4), ClinicalTrials.gov identifier, NCT01491672.
