The introduction of targeted therapies over the past 10 years revolutionized the treatment of metastatic renal cell carcinoma (mRCC). The next 10 years hold promise for even greater expansion of the therapeutic armamentarium for mRCC. A number of recently completed and ongoing trials have explored the use of antivascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TKIs) and mammalian target of rapamycin (mTOR) inhibitors in the adjuvant setting, the use of predictive biomarkers to guide personalized medicine, as well as new systemic treatments and combination therapies for mRCC.

Treatment Paradigm

The treatment paradigm for advanced and metastatic renal cell carcinoma (mRCC) has evolved rapidly since the arrival of targeted therapies and novel immunotherapies. mRCC was previously treated only with cytokines. However, discoveries of mutations affecting the von Hippel–Lindau tumor suppressor gene (leading to increased expression of VEGF and hypoxia inducible factor/HIF-1) and of deregulations in the phosphatidylinositol-3 kinase/AKT/mTOR pathway (resulting in tumor angiogenesis, cell proliferation, and tumor growth) have led to the development of numerous targeted therapies. The U.S. Food and Drug Administration (FDA) has thus approved a total of nine targeted therapies since 2005, including VEGF tyrosine kinase inhibitors (sunitinib, pazopanib, axitinib, sorafenib, and lenvatinib), a monoclonal antibody targeting VEGF (bevacizumab), mTOR inhibitors (temsirolimus and everolimus), and a multityrosine kinase inhibitor (cabozantinib). Furthermore, the development of immune checkpoint inhibitors has again shifted the mRCC therapeutic landscape with the FDA’s approval of nivolumab. Herein, we discuss the unprecedented changes in the field of clear cell histology mRCC in both the first-line and salvage settings, and we also discuss future therapies and recommend a treatment paradigm on sequencing of these agents.

Phase Iii

The agents currently approved for use in metastatic renal cell carcinoma (mRCC) can be divided broadly into two categories: (1) vascular endothelial growth factor receptor (VEGFR)-directed therapies or (2) inhibitors of the mammalian target of rapamycin (mTOR). The latter category includes everolimus and temsirolimus, both approved for distinct indications in mRCC. Everolimus gained its approval on the basis of phase III data showing a benefit in progression-free survival relative to placebo in patients previously treated with sunitinib and/or sorafenib. In contrast, temsirolimus was approved on the basis of a phase III trial in treatment-naïve patients with poor-risk mRCC, demonstrating an improvement in overall survival relative to interferon-alfa. While these pivotal trials have created unique positions for everolimus and temsirolimus in current clinical algorithms, the role of mTOR inhibitors in mRCC is being steadily revised and expanded through ongoing trials testing novel sequences and combinations. The clinical development of mTOR inhibitors is outlined herein.

Metastatic Rcc

Localized renal cell carcinoma (RCC) is often curable by surgery alone. However, metastatic RCC is generally incurable. In the 1990s, immunotherapy in the form of cytokines was the mainstay of treatment for metastatic RCC. However, responses were seen in only a minority of highly selected patients with substantial treatment-related toxicities. The advent of targeted agents such as vascular endothelial growth factor tyrosine kinase inhibitors VEGF-TKIs and mammalian target of rapamycin (mTOR) inhibitors led to a change in this paradigm due to improved response rates and progression-free survival, a better safety profile, and the convenience of oral administration. However, most patients ultimately progress with about 12% being alive at 5 years. In contrast, durable responses lasting 10 years or more are noted in a minority of those treated with cytokines. More recently, an improved overall survival with newer forms of immunotherapy in other malignancies (such as melanoma and prostate cancer) has led to a resurgence of interest in immune therapies in metastatic RCC. In this review we discuss the rationale for immunotherapy and recent developments in immunotherapeutic strategies for treating metastatic RCC.

AbstractThe introduction of novel targeted therapies during the last 2 decades has led to a significant improvement in patients' clinical outcomes with renal cell carcinoma. However, this improvement came at the price of a whole new spectrum of adverse events, including renal toxicity. Systemic treatment of patients with kidney neoplasms who often present with impairment of kidney function, even prior to treatment, poses an increasing diagnostic and therapeutic challenge for clinicians. Common lifestyle-related comorbidities, i.e., hypertension and diabetes, may contribute to further impairment of kidney function. The lack of official guidelines and the exclusion of patients with reduced kidney function from the clinical trials of recently approved drugs complicate the issue even further. Early detection and correct management of renal toxic effects are crucial to preserve kidney function and ensure the optimal administration of life-prolonging therapies. This review presents detailed information on the renal toxicities of three groups of drugs commonly used in renal cell carcinoma treatment: tyrosine kinase inhibitors, mammalian target of rapamycin inhibitors, and immune checkpoint inhibitors. We outline the incidence and underlying mechanisms of renal adverse effects with a focus on patients on renal replacement therapy, as well as present suggestions for their management.

585 Background: Everolimus is a mammalian target of rapamycin (mTOR) inhibitor. It gained approval based on the results of the RECORD-1 trial, which included patients with metastatic renal cell carcinoma (mRCC) whose disease progressed after receiving vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TKIs). Bevacizumab is a monoclonal antibody targeting angiogenesis that is approved in patients (pts) with mRCC. AVATOR was the 1st study to explore the sequential use of bevacizumab followed by everolimus but with limited number of pts. Methods: In order to further explore this sequence pooled data from the AVATOR, CHANGE and TRAIN studies were analysed retrospectively. All pts had mRCC and were previously or currently treated with everolimus after failure of bevacizumab ± IFN. The primary end point was everolimus time to progression (TTP). Secondary end points were related to the overall survival (OS) of patients receiving the drug sequence, everolimus treatment and safety. Results: 89 pts were included in the analysis. Median age was 68 years [18-90]. At everolimus initiation ECOG was 0-1 for 72% pts and 16% were classified as poor prognosis from Heng classification. Exploring the duration of second-line everolimus treatment, 32% of patients received less than 3 months of everolimus and 35% received at least 6 months of treatment. At the time of data analysis, 20 pts (24%) were still receiving everolimus. Pts receiving everolimus after bevacizumab experienced a median TTP of 6 months [95%CI 4 - 14]. Median OS was not reached for everolimus second-line therapy. At 36 months after the start of first-line therapy, 60.4% of pts were still alive. All grades of common adverse events were consistent with the known safety profile of everolimus. Conclusions: The larger size of this cohort confirms the signal previously seen with AVATOR that the sequence of bevacizumab followed by everolimus displays interesting efficacy with not unexpected toxicity from everolimus and compares favourably with RECORD-1.

Medical Needs

Advanced imaging techniques for diagnosis have increased awareness on the benefits of brain screening, facilitated effective control of extracranial disease, and prolonged life expectancy of metastatic renal cell carcinoma (mRCC) patients. Brain metastasis (BM) in patients with mRCC (RCC-BM) is associated with grave prognoses, a high degree of morbidity, dedicated assessment, and unresponsiveness to conventional systemic therapeutics. The therapeutic landscape of RCC-BM is rapidly changing; however, survival outcomes remain poor despite standard surgery and radiation, highlighting the unmet medical needs and the requisite for advancement in systemic therapies. Immune checkpoint inhibitors (ICIs) are one of the most promising strategies to treat RCC-BM. Understanding the role of brain-specific tumor immune microenvironment (TIME) is important for developing rationale-driven ICI-based combination strategies that circumvent tumor intrinsic and extrinsic factors and complex positive feedback loops associated with resistance to ICIs in RCC-BM via combination with ICIs involving other immunological pathways, anti-antiangiogenic multiple tyrosine kinase inhibitors, and radiotherapy; therefore, novel combination approaches are being developed for synergistic potential against RCC-BM; however, further prospective investigations with longer follow-up periods are required to improve the efficacy and safety of combination treatments and to elucidate dynamic predictive biomarkers depending on the interactions in the brain TIME.

In recent years, the management of metastatic renal cell carcinoma (mRCC) has been revolutionized by the advent of targeted therapies. Multitargeted kinase inhibitors (such as sunitinib, sorafenib, pazopanib, and axitinib), the vascular endothelial growth factor inhibitor bevacizumab, and mammalian target of rapamycin inhibitors (such as everolimus and temsirolimus) have become the standard of care for the palliation of metastatic disease. Unfortunately, cumulative toxicities and the lack of marked benefits have prevented the combined use of most molecularly targeted agents. Selected patients with mRCC benefit from immunotherapy, as subsets of patients can experience long-term disease remission or complete response with high-dose interleukin-2. In order to optimize the value of immunotherapy, improvements in the selection of drugs and combinations with novel immunomodulatory agents must be pursued.

403 Background: The mTOR inhibitors have improved outcomes for pts with metastatic renal cell carcinoma (mRCC) but the duration of benefit is variable. Currently there are no predictive biomarkers for pre-selecting pts who are likely to respond to these agents. We undertook an exploratory translational study evaluating cytogenetic changes in the context of response to everolimus therapy. Methods: 10 pts with mRCC treated with everolimus therapy were enrolled. Pre-treatment paraffin-embedded tissue specimens were analysed for cytogenetic changes using fluorescence in situ hybridisation (FISH) and clinical data including PFS (RECIST 1.1) were obtained. The gene probes chosen for this analysis were; VHL, FHIT, FGFR1/3, PDGFb, PDGFRb, EGFR, MYC and IGH@. Results: Results are displayed in the table below. The median PFS was 8.25mo (months). Eight pts were treated 1st-line (on clinical trial), one 2nd-line and one 3rd-line. The longest responder (PFS 25.5mo, 3rd-line) had a normal VHL status but loss of FHIT. Two pts with the longest PFS and one with a PFS of 5.5mo had gain of both PDGFb and PDGFRb. Gain of FGFR1 and FGFR3 was seen in two and three pts respectively. Two specimens were unsuitable for full analysis. Conclusions: Loss of FHIT but a normal VHL status was seen in one pt with mRCC who had an enduring response to everolimus. Concomitant gain of PDGFband PDGFRb was observed in three pts with a good response. FGFR1/3 may be of relevance in the setting of alternative targeted therapies. Further research evaluating the utility of these potential biomarkers is required. [Table: see text]

Personalized Approach

Context.—The prognosis for patients with metastatic renal cell carcinoma is poor, with an average 5-year survival of approximately 10%. Use of traditional cytokine therapy, specifically high-dose interleukin 2, is limited by significant toxicity. Better understanding of the molecular pathogenesis of renal cell carcinoma has led to the development of targeted therapies to inhibit specific cellular pathways leading to tumorigenesis. These drugs provide improved survival with a more favorable toxicity profile. There is ongoing investigation of markers that predict response of an individual patient to different targeted therapies. Objective.—To explain the molecular basis for vascular endothelial growth factor inhibitor (antiangiogenic) and mammalian target of rapamycin inhibitor therapies for renal cell carcinoma, summarize the clinical trials demonstrating the effectiveness of these drugs, and describe the biomarkers shown to correlate with outcome in patients treated with targeted therapy. Data Sources.—All included sources are from peer-reviewed journals in PubMed (US National Library of Medicine). Conclusion.—Emerging evidence shows promise that biomarkers will be useful for predicting an individual patient's response to targeted therapy, leading to a more personalized approach to treating renal cell carcinoma.
