Clinical experience with everolimus in the second-line treatment of advanced renal cell carcinoma.

ABSTRACT: Everolimus is an oral inhibitor of mammalian target of rapamycin (mTOR-I) and is currently approved for the treatment of metastatic renal cell carcinoma (mRCC) after failure of first-line vascular endothelial growth factor receptor tyrosine kinase inhibitor (TKI). In this narrative review, we aim to report the available evidence about the use of everolimus as second-line therapy for mRCC. A literature search was performed using PubMed/MEDLINE and abstracts from major conferences on clinical oncology as sources. We report data from prospective as well as retrospective and real world data studies and we analyze the safety and efficacy profile of everolimus as second-line therapy for mRCC. Although different drugs are currently available for the second-line treatment of mRCC, everolimus represents a feasible and safe option in this setting, especially for patients who have experienced high-grade toxicity or are still carrying TKI-related toxicities from first-line treatment.

Project description:Currently, conventional treatments for metastatic RCC (mRCC) include immune-based combination regimens and/or targeted therapies, the latter mainly acting on angiogenesis, a key element of the process of tumor growth and spread. Although these agents proved able to improve patients' outcomes, drug resistance and disease progression are still experienced by a substantial number of VEGFR-TKIs-treated mRCC patients. Following the inhibition of the VEGF/VEGFRs axis, two strategies have emerged: either specifically targeting resistance pathways, at the same time continuing to inhibit angiogenesis, or using a completely different approach aimed at re-activating the immune system through the use of inhibitors of specific negative immune checkpoints. These two approaches, practically represented by the use of either cabozantinib or nivolumab, seem to remain a rational therapeutic approach also when first-line immune-based combinations are used. The objective of this study is to design a preferential therapeutic pathway for the second-line treatment of mRCC. The procedure applied in this project was a group discussion, based on the Nominal Group Technique (NGT) method in a meeting session, aimed at defining the therapeutic choice for the second-line treatment of mRCC. The NGT process defined the most relevant parameters that, according to the interviewed panelists, clinicians should consider for the selection of the second-line therapy in the context of advanced renal cell carcinoma of mRCC. The algorithm developed for the treatment selection as a result of this process should thus be considered by clinicians as reference for therapy selection.Plain language summaryThe result of this paper was the definition of an algorithm intended to suggest a preferential therapeutic pathway considering both the outputs of the Nominal Group Technique (NGT) process and the actual clinical practice and the experience of selected panelists. During the NGT process and the discussion phase, panelists defined the most important parameters to be included in the algorithm that are important for the treatment definition. Cabozantinib and nivolumab are identified as the most reasonable therapeutic options for patients progressing after first-line treatment and are the medication options included in the algorithm for therapy selection.

Project description:Nivolumab, a programmed death 1 (PD-1) checkpoint inhibitor, was associated with encouraging overall survival in uncontrolled studies involving previously treated patients with advanced renal-cell carcinoma. This randomized, open-label, phase 3 study compared nivolumab with everolimus in patients with renal-cell carcinoma who had received previous treatment.A total of 821 patients with advanced clear-cell renal-cell carcinoma for which they had received previous treatment with one or two regimens of antiangiogenic therapy were randomly assigned (in a 1:1 ratio) to receive 3 mg of nivolumab per kilogram of body weight intravenously every 2 weeks or a 10-mg everolimus tablet orally once daily. The primary end point was overall survival. The secondary end points included the objective response rate and safety.The median overall survival was 25.0 months (95% confidence interval [CI], 21.8 to not estimable) with nivolumab and 19.6 months (95% CI, 17.6 to 23.1) with everolimus. The hazard ratio for death with nivolumab versus everolimus was 0.73 (98.5% CI, 0.57 to 0.93; P=0.002), which met the prespecified criterion for superiority (P?0.0148). The objective response rate was greater with nivolumab than with everolimus (25% vs. 5%; odds ratio, 5.98 [95% CI, 3.68 to 9.72]; P<0.001). The median progression-free survival was 4.6 months (95% CI, 3.7 to 5.4) with nivolumab and 4.4 months (95% CI, 3.7 to 5.5) with everolimus (hazard ratio, 0.88; 95% CI, 0.75 to 1.03; P=0.11). Grade 3 or 4 treatment-related adverse events occurred in 19% of the patients receiving nivolumab and in 37% of the patients receiving everolimus; the most common event with nivolumab was fatigue (in 2% of the patients), and the most common event with everolimus was anemia (in 8%).Among patients with previously treated advanced renal-cell carcinoma, overall survival was longer and fewer grade 3 or 4 adverse events occurred with nivolumab than with everolimus.

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.
