Optimizing treatment of renal cell carcinoma with VEGFR-TKIs: a comparison of clinical pharmacology and drug-drug interactions of anti-angiogenic drugs.
Anti-angiogenic treatment is an important option that has changed the therapeutic landscape in various tumors, particularly in patients affected by renal cell carcinoma (RCC). Agents that block signaling pathways governing tumor angiogenesis have raised high expectations among clinicians. Vascular endothelial growth factor receptor-tyrosine kinase inhibitors (VEGFR-TKIs) comprise a heterogeneous class of drugs with distinct pharmacological profiles, including potency, selectivity, pharmacokinetics and drug-drug interactions. Among them, tivozanib is one of the last TKIs introduced in the clinical practice; this drug selectively targets VEGFRs, it is characterized by a favorable pharmacokinetics and safety profile and has been approved as first-line treatment for patients with metastatic RCC (mRCC). In this article, we describe the clinical pharmacology of selected VEGFR-TKIs used for the treatment of mRCC, highlighting the relevant differences; moreover we aim to define the main pharmacologic characteristics of these drug. Topics: Angiogenesis Inhibitors; Anilides; Axitinib; Carcinoma, Renal Cell; Drug Interactions; Humans; Indazoles; Kidney Neoplasms; Phenylurea Compounds; Protein Kinase Inhibitors; Pyridines; Pyrimidines; Quinolines; Receptors, Vascular Endothelial Growth Factor; Sorafenib; Sulfonamides; Sunitinib | 2020 |
Second-line tyrosine kinase inhibitor-therapy after immunotherapy-failure.
Most contemporary metastatic renal-cell carcinoma patients receive first-line immunotherapy and tyrosine kinase inhibitor (TKI) combination or immunotherapy-immunotherapy combination, as first-line standards of care. However, second-line therapy choices are less well established. To address this void, we examined existing evidence supporting second and subsequent-line treatment options after immunotherapy-based combination therapy.. Evidence regarding efficacy of second-line therapy after immunotherapy-based combination is mainly retrospective, except for axitinib, which is the only TKI with prospective efficacy data in this setting. Cabozantinib demonstrated excellent second-line progression-free survival (PFS) that remained in third or later line use, albeit based on small numbers of observations. Moreover, pazopanib demonstrated excellent PFS, but showed wider variability in PFS rates. Sunitinib's PFS rates appeared lower than for axitinib, cabozantinib or pazopanib. Finally, inhibitors of the mammalian target of rapamycin pathway appeared to offer even lower efficacy than any TKI after immunotherapy-based therapy combinations.. All available contemporary evidence about TKI efficacy after immunotherapy-based therapy combinations is based on institutional studies. No major differences in efficacy for the examined TKIs after immunotherapy-based combination therapies were recorded. In general, these showed similar efficacy to their efficacy data recorded in first-line.

Pazopanib, Cabozantinib, and Vandetanib in the Treatment of Progressive Medullary Thyroid Cancer with a Special Focus on the Adverse Effects on Hypertension.
Medullary thyroid cancer (MTC) is a rare malignancy with a poor prognosis. First line therapy is surgery, which is the only curative method of the disease. However, in non-operable cases or with tumor progression and metastases, a systemic treatment is necessary. This form of cancer is often insensitive to conventional chemotherapy, but the use of tyrosine kinase inhibitors (TKIs), such as pazopanib, cabozantinib, and vandetanib, has shown promising results with an increase in progression-free survival and prolonged lifetime. Therefore, we focused on the pharmacological characteristics of TKIs, their mechanism of action, their application as a secondary treatment option for MTC, their efficacy as a cancer drug treatment, and reviewed the ongoing clinical trials. TKIs also act systemically causing various adverse events (AEs). One common AE of this treatment is hypertension, known to be associated with cardiovascular disease and can therefore potentially worsen the well-being of the treated patients. The available treatment strategies of drug-induced hypertension were discussed. The mechanism behind the development of hypertension is still unclear. Therefore, the treatment of this AE remains symptomatic. Thus, future studies are necessary to investigate the link between tumor growth inhibition and hypertension. In addition, optimized, individual treatment strategies should be implemented.

HOW TO CHOOSE THE APPROPRIATE SECOND-LINE TREATMENT?: The treatment of advanced or metastatic renal cell cancer (RCC) has dramatically improved in the past ten years. In the second-line setting, for patients who progressed on prior antiangiogenic therapy (mainly the VEGFR tyrosine kinase inhibitors (TKI) sunitinib or pazopanib), axitinib and everolimus have been recommended. Since 2015, other drugs have proven their efficacy and are currently considered the standard of care: cabozantinib (TKI that targets VEGFR, MET and AXL) and nivolumab (first anti-PD-1 check point inhibitor). Lenvatinib has also demonstrated promising results in association with everolimus, but this combination is not available in France. The optimal treatment choice for a given patient is challenging for the clinician when facing multiple options. In this article, we review the efficacy, safety and quality of life results of the main pivotal clinical studies involving advanced or metastatic RCC in the second-line setting, to help clinicians in selecting the most appropriate treatment. Beyond that, it is important to define all the sequencing strategy for patients to successively receive all the drugs that have demonstrated an increase in overall survival.

A Systematic Review and Meta-analysis Comparing the Effectiveness and Adverse Effects of Different Systemic Treatments for Non-clear Cell Renal Cell Carcinoma.
While vascular endothelial growth factor-targeted therapy and mammalian target of rapamycin inhibition are effective strategies in treating clear cell renal cell carcinoma (ccRCC), the most effective therapeutic approach for patients with non-clear cell RCC (non-ccRCC) is unknown.. To systematically review relevant literature comparing the oncological outcomes and adverse events of different systemic therapies for patients with metastatic non-ccRCC.. Relevant databases including MEDLINE, Embase, and the Cochrane Library were searched up to March 24, 2016. Only comparative studies were included. Risk of bias and confounding assessments were performed. A meta-analysis was planned for and only performed if methodologically appropriate; otherwise, a narrative synthesis was undertaken.. The literature search identified 812 potential titles and abstracts. Five randomized controlled trials, recruiting a total of 365 patients, were included. Three studies compared sunitinib against everolimus, one of which reported the results for non-ccRCC as a subgroup rather than as an entire randomized cohort. Individually, the studies showed a trend towards favoring sunitinib in terms of overall survival and progression-free survival (PFS; Everolimus versus Sunitinib in Patients with Metastatic Non-clear Cell Renal Cell Carcinoma hazard ratio [HR]: 1.41, 80% confidence interval [CI] 1.03-1.92 and 1.41, 95% CI: 0.88-2.27, Evaluation in Metastatic Non-clear Cell Renal Cell Carcinoma HR: 1.16, 95% CI: 0.67-2.01, Efficacy and Safety Comparison of RAD001 Versus Sunitinib in the First-line and Second-line Treatment of Patients with Metastatic Renal Cell Carcinoma HR: 1.5, 95% CI: 0.9-2.8), but this trend did not reach statistical significance in any study. Meta-analysis was performed on two studies which solely recruited patients with non-ccRCC reporting on PFS, the results of which were inconclusive (HR: 1.30, 95% CI: 0.91-1.86). Sunitinib was associated with more Grade 3-4 adverse events than everolimus, although this was not statistically significant.. This systematic review and meta-analysis represent a robust summary of the evidence base for systemic treatment of metastatic non-ccRCC. The results show a trend towards favoring vascular endothelial growth factor-targeted therapy for PFS and overall survival compared with mammalian target of rapamycin inhibitors, although statistical significance was not reached. The relative benefits and harms of these treatments remain uncertain. Further research, either in the form of an individual patient data meta-analysis involving all relevant trials, or a randomized controlled trial with sufficient power to detect potential differences between treatments, is needed.. We examined the literature to determine the most effective treatments for advanced kidney cancer patients whose tumors are not of the clear cell subtype. The results suggest that a drug called sunitinib might be more effective than everolimus, but the statistics supporting this statement are not yet entirely reliable. Further research is required to clarify this unmet medical need.

[Side effect management of tyrosine kinase inhibitors in urology : Fatigue and hypothyroidism].
Not only has the use of tyrosine kinase inhibitors (TKI) for the treatment of metastatic renal cell carcinomas (mRCC) changed the therapeutic options for this disease significantly, but with the occurrence of typical side effects this therapy also poses a challenge for the treating physician. Fatigue und hypothyroidism are two common side effects of TKI therapy that can often appear simultaneously. By reducing the patients' quality of life these side effects often lead to a discontinuation of therapy. With this review we want to give the treating physician an overview of the classification and the specific treatment of TKI-induced fatigue and hypothyroidism in order to maximize patients' compliance and the therapeutic efficacy of TKI therapy.

Improvement in survival end points of patients with metastatic renal cell carcinoma through sequential targeted therapy.
Survival of patients with metastatic renal cell carcinoma (mRCC) has improved since the advent of targeted therapy. Approved agents include the multi-targeted tyrosine kinase inhibitors (TKIs) sunitinib, sorafenib, axitinib, pazopanib, cabozantinib, and lenvatinib (approved in combination with everolimus), the anti-VEGF monoclonal antibody bevacizumab, the mammalian target of rapamycin (mTOR) inhibitors everolimus and temsirolimus, and the programmed death-1 (PD-1) targeted immune checkpoint inhibitor nivolumab. The identification of predictive and prognostic factors of survival is increasing, and both clinical predictive factors and pathology-related prognostic factors are being evaluated. Serum-based biomarkers and certain histologic subtypes of RCC, as well as clinical factors such as dose intensity and the development of some class effect adverse events, have been identified as predictors of survival. Expression levels of microRNAs, expression of chemokine receptor 4, hypermethylation of certain genes, VEGF polymorphisms, and elevation of plasma fibrinogen or d-dimer have been shown to be prognostic indicators of survival. In the future, prognosis and treatment of patients with mRCC might be based on genomic classification, especially of the 4 most commonly mutated genes in RCC (VHL, PBRM1, BAP1, and SETD2). Median overall survival has improved for patients treated with a first-line targeted agent compared with survival of patients treated with first-line interferon-α, and results of clinical trials have shown a survival benefit of sequential treatment with targeted agents. Prognosis of patients with mRCC will likely improve with optimization and individualization of current sequential treatment with targeted agents.

Treatment of advanced thyroid cancer: role of molecularly targeted therapies.
Advanced thyroid cancer is not amenable to therapy with conventional cytotoxic chemotherapy. However, newer advances in the understanding of the molecular pathogenesis of different subtypes of thyroid cancer have provided new opportunities for the evaluation of molecularly targeted therapies. This has led to multiple clinical trials using various multi-kinase inhibitors and the subsequent US FDA approval of sorafenib for differentiated thyroid cancer and vandetanib and cabozantinib for medullary thyroid carcinoma. This review provides a summary of the current literature for the treatment of advanced thyroid carcinoma and future directions in this disease.

Novel molecular targeted therapies for refractory thyroid cancer.
The incidence of thyroid cancer continues to increase and this neoplasia remains the most common endocrine malignancy. No effective systemic treatment currently exists for iodine-refractory differentiated or medullary thyroid carcinoma, but recent advances in the pathogenesis of these diseases have revealed key targets that are now being evaluated in the clinical setting. RET (rearranged during transfection)/PTC (papillary thyroid carcinoma) gene rearrangements, B-Raf gene mutations, and vascular endothelial growth factor receptor 2 (VEGFR-2) angiogenesis pathways are some of the known genetic alterations playing a crucial role in the development of thyroid cancer. Several novel agents have demonstrated promising responses. Of the treatments studied, multi-kinase inhibitors such as axitinib, sorafenib, motesanib, and XL-184 have shown to be the most effective by inducing clinical responses and stabilizing the disease process. Randomized clinical trials are currently evaluating these agents, results that may soon change the management of thyroid cancer.

Outcomes based on prior therapy in the phase 3 METEOR trial of cabozantinib versus everolimus in advanced renal cell carcinoma.
In the phase 3 METEOR trial, cabozantinib improved progression-free survival (PFS), objective response rate (ORR), and overall survival (OS) versus everolimus in patients with advanced renal cell carcinoma (RCC), after prior antiangiogenic therapy.. Outcomes were evaluated for subgroups defined by prior therapy with sunitinib or pazopanib as the only prior VEGFR inhibitor, or prior anti-PD-1/PD-L1 therapy.. For the prior sunitinib subgroup (N = 267), median PFS for cabozantinib versus everolimus was 9.1 versus 3.7 months (HR 0.43, 95% CI 0.32-0.59), ORR was 16% versus 3%, and median OS was 21.4 versus 16.5 months (HR 0.66, 95% CI 0.47-0.93). For the prior pazopanib subgroup (N = 171), median PFS for cabozantinib versus everolimus was 7.4 versus 5.1 months (HR 0.67, 95% CI 0.45-0.99), ORR was 19% versus 4%, and median OS was 22.0 versus 17.5 months (HR 0.66, 95% CI 0.42-1.04). For prior anti-PD-1/PD-L1 therapy (N = 32), median PFS was not reached for cabozantinib versus 4.1 months for everolimus (HR 0.22, 95% CI 0.07-0.65), ORR was 22% versus 0%, and median OS was not reached versus 16.3 months (HR 0.56, 95% CI 0.21-1.52).. Cabozantinib was associated with improved clinical outcomes versus everolimus in patients with advanced RCC, irrespective of prior therapy, including checkpoint inhibitor therapy.

The impact of proton-pump inhibitors administered with tyrosine kinase inhibitors in patients with metastatic renal cell carcinoma.
Tyrosine kinase inhibitors (TKIs) are the backbone of the systemic treatment for patients with metastatic renal cell carcinoma (mRCC). TKIs such as pazopanib and cabozantinib can interact with other drugs concomitantly administered, particularly with proton-pump inhibitors (PPIs), possibly impacting the effectiveness of the anticancer treatment and patients outcome. Few data are available about this interaction. We conducted a multicenter retrospective observational data collection of patients with mRCC treated with pazopanib or cabozantinib between January 2012 and December 2020 in nine Italian centers. Univariate and multivariate analyses were performed. The aim was to describe the impact of baseline concomitant PPIs on the outcome of patients to pazopanib and cabozantinib in terms of response, progression-free survival (PFS) and overall survival (OS), toxicity, and treatment compliance. The use of PPI in our study population (301 patients) significantly influenced the effectiveness of TKIs with worse PFS (16.3 vs. 9.9 months; P < 0.001) and OS (30.6 vs. 18.4 months; P = 0.013) in patients taking PPI at TKI initiation. This detrimental effect was maintained both in the pazopanib and cabozantinib groups. The use of PPI influenced the toxicity and TKI treatment compliance with a reduction of dose or schedule modifications, and treatment interruptions in the population taking PPIs. Our study demonstrates that the use of PPIs can significantly influence the outcome and compliance of patients with mRCC to TKI treatment, suggesting the importance of a more careful selection of patients who need a gastroprotective therapy, avoiding indiscriminate use of PPIs.

Tailoring treatment with cabozantinib or pazopanib in patients with metastatic renal cell carcinoma: does it affect outcome?
Metastatic renal cell carcinoma (mRCC) treatment is still largely based on TKI use. Treatment adjustment due to toxicities is often needed. The aim of the present study was to determine the impact of treatment modifications on the outcome of mRCC patients treated with cabozantinib or pazopanib.. This retrospective multicenter study enrolled consecutive patients receiving cabozantinib or pazopanib between January 2012 and December 2020. We evaluated the correlation of TKI treatment modifications with grade 3-4 toxicities and progression-free (PFS) and overall survival (OS). We also performed a landmark analysis excluding patients who did not undergo at least 5 months of therapy.. Among 301 patients, 179 (59%) were treated with pazopanib, 122 (41%) with cabozantinib. Treatment modifications were related to grade 3-4 toxicities (. Tailoring treatment with pazopanib and cabozantinib was associated with better PFS/OS.

Interaction of Some Amino-Nitrile Derivatives with Vascular Endothelial Growth Factor Receptor 1 (VEGFR1) Using a Theoretical Model.
Some studies indicate that the angiogenesis process is related to vascular endothelial growth factor, which can interact with endothelial cell surface receptors (VEGF-R1, VEGF-R2, and VEGF-R3); this biochemical process and other factors result in the promotion and growth of new blood vessels under normal conditions. However, some studies indicate that this phenomenon could also occur in cancer cells. It is important to mention that some amino derivatives have been prepared as VEGF-R1 inhibitors; however, their interaction with VEGF-R1 is not clear, perhaps due to different experimental approaches or differences in their chemical structure.. The aim of this study was to evaluate the theoretical interaction of several amino-nitrile derivatives (Compounds 1 to 38) with VEGF-R1.. The theoretical interaction of amino-nitrile derivatives with VEGF-R1 was carried out using the 3hng protein as the theoretical model. In addition, cabozantinib, pazopanib, regorafenib, and sorafenib were used as controls in the DockingServer program.. The results showed different amino acid residues involved in the interaction of amino-nitrile derivatives with the 3hng protein surface compared with the controls. In addition, the inhibition constant (Ki) was lower for Compounds 10 and 34 than for cabozantinib. Other results show that Ki for Compounds 9, 10, 14, 27-29 and 34-36 was lower in comparison with pazopanib, regorafenib, and sorafenib.. All theoretical data suggest that amino-nitrile derivatives could produce changes in the growth of some cancer cell lines through VEGFR-1 inhibition. Therefore, these amino-nitrile derivatives could be a therapeutic alternative to treat some types of cancer.

Integrating Red Blood Cell Features and Hemoglobin Levels in Metastatic Renal Cell Carcinoma Patients Treated with Pazopanib or Cabozantinib: An Easily Exploitable Prognostic Score.
The advent of immune checkpoint inhibitors (ICIs) has revolutionized the metastatic renal cell carcinoma (mRCC) therapeutic landscape. Nevertheless, tyrosine-kinase inhibitors (TKIs) targeting the vascular endothelial growth factor (VEGF) axis still play a key role. The aim of the present study was to explore the prognostic performance of an integrated blood score, based on hemoglobin (Hb) concentration, mean corpuscular volume (MCV), and red cell distribution width (RDW), in mRCC patients treated with anti-VEGF TKIs. The primary endpoint was to correlate Hb, MCV, and RDW with progression-free survival (PFS) and overall survival (OS).. Our multicenter retrospective observational study involved mRCC patients treated with pazopanib or cabozantinib from January 2012 to December 2020 in nine Italian centers. Clinical records and laboratory data, including Hb levels, MCV, and RDW, were collected at baseline. Descriptive statistics and univariate and multivariate analyses were performed.. We enrolled 301 mRCC patients of which 179 (59%) underwent pazopanib, and 122 (41%) cabozantinib. We considered baseline Hb ≥12 g/dL, MCV >87 fL, and RDW ≤16% as good prognostic factors; hence, developing a multiparametric score capable of delineating 4 different categories. The number of good prognostic factors was associated with significantly longer PFS and OS (. Our analyses demonstrate the prognostic role of a multiparametric score based on easily exploitable blood parameters, such as Hb concentration, MCV, and RDW. The red blood cell-based score may underlie the upregulation of the HIF-1α pathway and VEGF axis, thereby identifying a selected population who is likely to benefit from TKI therapy.

Kinase activity profiling in renal cell carcinoma, benign renal tissue and in response to four different tyrosine kinase inhibitors.
Kinase activity is frequently altered in renal cell carcinoma (RCC), and tyrosine kinase inhibitors (TKIs) are part of the standard treatment strategy in patients with metastatic disease. However, there are still no established biomarkers to predict clinical benefits of a specific TKI.

Combination antiangiogenic tyrosine kinase inhibition and anti-PD1 immunotherapy in metastatic renal cell carcinoma: A retrospective analysis of safety, tolerance, and clinical outcomes.
Two separate antiangiogenic tyrosine kinase inhibitors (TKIs) and immunotherapy (IO) combinations are FDA-approved as front-line treatment for metastatic renal cell carcinoma (mRCC). Little is known about off-protocol and post-front-line experience with combination TKI-IO approaches.. We conducted a retrospective analysis of mRCC patients who received combination TKI-IO post-first-line therapy between November 2015 and January 2019 at MD Anderson Cancer Center and Duke Cancer Institute. Chart review detailed patient characteristics, treatments, toxicity, and survival. Independent radiologists, blinded to clinical data, assessed best radiographic response using RECIST v1.1.. We identified 48 mRCC patients for inclusion: median age 65 years, 75.0% clear cell histology, 68.8% IMDC intermediate risk, and median two prior systemic therapies. TKI-IO combinations included nivolumab-cabozantinib (N +C; 24 patients), nivolumab-pazopanib (N+P; 13), nivolumab-axitinib (6), nivolumab-lenvatinib (2), and nivolumab-ipilimumab-cabozantinib (3). The median progression-free survival was 11.6 months and the median overall survival was not reached. Response data were available in 45 patients: complete response (CR; n = 3, 6.7%), partial response (PR; 20, 44.4%), stable disease (SD; 19, 42.2%), and progressive disease (3, 6.7%). Overall response rate was 51% and disease control rate (CR+PR+SD) was 93%. Only one patient had a grade ≥3 adverse event.. To our knowledge, this is the first case series reporting off-label use of combination TKI-IO for mRCC. TKI-IO combinations, particularly N+P and N+C, are well tolerated and efficacious. Although further prospective research is essential, slow disease progression on IO or TKI monotherapy may be safely controlled with addition of either TKI or IO.

Polycystic Liver Disease in a Patient With Metastatic Renal Cell Carcinoma: A Case Report.
We report a case of rapid evolution of polycystic liver disease in a 76-year-old patient with metastatic renal cell carcinoma who underwent treatment with numerous antineoplastic agents. The aim was to identify a causative etiology for these hepatic cysts of unclear origin. The cystic lesions of the patient were ultimately innumerable and developed rapidly, more than tripling the total liver volume from complete absence over the course of 24 months. The hepatic lesions continued to grow despite an otherwise moderate tumor response. Prior to patient death, the patient remained relatively asymptomatic from the cyst burden and was without signs of grossly metastatic disease. This rapid development of polycystic liver disease most likely represents a previously unseen medication side-effect of cabozantinib or pazopanib. It is important to identify adverse effects of novel antineoplastic agents in this time of oncological medical discovery.

Comprehensive analysis of copy number variance and sensitivity to common targeted therapy in clear cell renal cell carcinoma: In silico analysis with in vitro validation.
Chromosomal rearrangements are common in clear cell renal cell carcinoma (ccRCC) and their roles in mediating sensitivity to tyrosine kinase inhibitors (TKIs) and mTOR inhibitors (mTORi) remain elusive.. We developed an in silico strategy by screening copy number variance (CNV) that was potentially related to TKI or mTORi sensitivity in ccRCC by reproducing the TCGA and GDSC datasets. Candidate genes should be both significantly prognostic and related to drug sensitivity or resistance, and were then validated in vitro.. ADCYAP1 loss and GNAS gain were associated with sensitivity and resistance and to Cabozantinib, respectively. ACRBP gain and CTBP1 loss were associated with sensitivity and resistance and to Pazopanib, respectively. CDKN2A loss and SULT1A3 gain were associated with sensitivity and resistance and to Temsirolimus, respectively. CCNE1 gain was associated with resistance to Axitinib and LRP10 loss was associated with resistance to Sunitinib. Mutivariate analysis showed ADCYAP1, GNAS, and CCNE1 remained independently prognostic when adjusted for the rest.. Here we show CNVs of several genes that are associated with sensitivity and resistance to commonly used TKIs and mTORi in ccRCC. Further validation and functional analyses are therefore needed.

Treating metastatic clear-cell renal cell carcinoma: beyond immunotherapy.
First-line treatment for metastatic clear-cell renal cell carcinoma patients with intermediate and poor-risk features consists of a combination of immune checkpoint inhibitors (e.g., nivolumab + ipilimumab) or immunotherapy with an anti-vascular endothelial growth factor receptor (VEGFR) drug (e.g., axitinib). The subsequent line of therapy should be determined on the basis of previous treatments and approved drugs available, based on the results of randomized clinical trials. Unfortunately, no phase 3 trial has compared the safety and efficacy of drugs after immunotherapy; thus, drug choice is more empirical than evidence-based. As the tumor may still be anti-VEGFR drug-naïve, a tyrosine kinase inhibitor approved for first line treatment (e.g., sunitinib or pazopanib) may be beneficial. Because this is a second-line treatment, patients could also receive axitinib, cabozantinib, or a combination of lenvatinib and everolimus. The treating physician should choose an appropriate treatment according to the patient's age, comorbidities, and tolerability of previous checkpoint inhibitors, among other considerations. Cases of patients with renal cell carcinoma refractory to checkpoint inhibitor treatment are growing, warranting a review of the activity and safety of target therapies after immunotherapy.

Second-line targeted therapies after nivolumab-ipilimumab failure in metastatic renal cell carcinoma.
Nivolumab-ipilimumab demonstrated a survival benefit over sunitinib in first-line setting for metastatic renal cell carcinomas (mRCCs) and is becoming a new standard of care for naïve patients with intermediate or poor risk prognosis (International mRCC Database Consortium). The efficacy of subsequent vascular endothelial growth factor receptor tyrosine kinase inhibitors (TKIs) after nivolumab-ipilimumab failure remains unclear.. Medical records of mRCC patients treated with nivolumab-ipilimumab, who received subsequent TKI, as part of Checkmate 214 study were reviewed in 13 institutions. Baseline characteristics, outcome data including progression-free survival (PFS), response, overall survival (OS) and toxicities were retrospectively collected.. Overall 33 patients received subsequent TKI after nivolumab-ipilimumab failure. Median follow-up from start of subsequent TKI is 22 months (19-NR). Best response was assessed in 30 patients: 12 partial responses (36%), 13 stable diseases (39%) and five progressive diseases (15%). Median PFS from start of TKI was 8 months [5-13]. Median PFS with first-generation (sunitinib/pazopanib) and second-generation TKI (axitinib/cabozantinib) was 8 months [5-16] and 7 months (5-NA), respectively. PFS in second line was significantly longer in patients with a long first-line duration of response to the double immune checkpoint blockade (≥6 months) with 8 versus 5 months for short responder (<6 months) (p = 0.03). OS rate was 54% at 12 months. Toxicity was as expected: 42% developed at least one toxicity grade ≥3.. This is the first report of outcomes with TKI, after first-line nivolumab-ipilimumab failure. Median PFS suggests a sustained benefit of TKI and supports trials investigating the optimal sequence.

Prognostic effect of cytoreductive nephrectomy in synchronous metastatic renal cell carcinoma: a comparative study using inverse probability of treatment weighting.
To test the hypothesis that cytoreductive nephrectomy (CN) improves overall survival (OS) of patients with synchronous metastatic renal cell carcinoma (mRCC), who subsequently receive targeted therapies (TT).. We identified 261 patients who received TT for synchronous mRCC with or without prior CN. To achieve balance in baseline characteristics between groups, we used the inverse probability of treatment weighting (IPTW) method. We conducted OS analyses, including IPTW-adjusted Kaplan-Meier curves, Cox regression models, interaction term, and landmark and sensitivity analyses.. Of the 261 patients, 97 (37.2%) received CN and 164 (62.8%) did not. IPTW-adjusted analyses showed a statistically significant OS benefit for patients treated with CN (HR 0.63, 95% CI 0.46-0.83, P = 0.0015). While there was no statistically significant difference in OS at 3 months (P = 0.97), 6 months (P = 0.67), and 12 months (P = 0.11) from diagnosis, a benefit for the CN group was noted at 18 months (P = 0.005) and 24 months (P = 0.004). On interaction term analyses, the beneficial effect of CN increased with better performance status (P = 0.06), in women (P = 0.03), and in patients with thrombocytosis (P = 0.01).. IPTW-adjusted analysis of our patient cohort suggests that CN improves OS of patients with synchronous mRCC treated with TT. On the whole, the survival difference appears after 12 months. Specific subgroups may particularly benefit from CN, and these subgroups warrant further investigation in prospective trials.

Clinical Benefit from Tyrosine Kinase Inhibitors in Metastatic Merkel Cell Carcinoma: A Case Series of 5 Patients.
BACKGROUND Merkel cell carcinoma (MCC) is a rare but aggressive neuroendocrine skin cancer. The estimated 5-year survival of patients with metastatic disease is approximately 14%. Cytotoxic chemotherapy is associated with a modest median progression-free survival (PFS) of only 3 months. In recent studies, immunotherapy with anti-PD-1/anti-PD-L1 antibodies has demonstrated a high response rate in immunocompetent patients (>50% in chemotherapy-naïve patients) and responses are typically durable. However, approximately 50% of immunocompetent patients do not respond to immunotherapy. In addition, immunosuppressed patients have limited therapeutic options. Hence, there is a significant unmet need for effective treatments in these subpopulations. CASE REPORT We describe 5 patients (out of 24 total) with metastatic MCC who were treated with a vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor (TKI), either pazopanib (n=4) or cabozantinib (n=1), with clinical benefit. One patient had a complete response to pazopanib after 3 months of therapy. Four patients had stabilization of disease that lasted from 5 months to 3.5 years. In an immunosuppressed patient with psoriatic arthritis, stabilization of MCC was also associated with improvement in his arthritis that allowed cessation of immunosuppression. Patients did not develop any unusual toxicities from VEGFR-TKIs. CONCLUSIONS Treatment with VEGFR-TKIs demonstrated clinical benefit in this selected small group of patients with metastatic MCC. Prospective investigation of VEGFR-TKIs is warranted in this population, especially in patients with disease refractory to immunotherapy.

Eligibility for phase 3 clinical trials of systemic therapy in real-world patients with metastatic renal cell cancer managed in a rural region.
Previous research has identified disparities between urban and rural cancer care, including clinical trial access. Therefore, we addressed three different questions in patients with metastatic renal cell cancer managed according to national guidelines in a rural Norwegian standard practice setting. (1) How many patients would have been eligible for three recent landmark randomized clinical trials? (2) Is survival different between eligible and non-eligible patients receiving first-line systemic therapy? (3) Is survival different between eligible patients and published trial results? We performed a retrospective analysis of 101 consecutive patients (2006-2016). Only 52% of the patients were eligible for the first-line study of pazopanib versus sunitinib. The main reasons for violating inclusion or exclusion criteria were presence of brain metastases, absence of clear cell histology, and poor performance status. Even fewer patients were eligible for trials of nivolumab and cabozantinib in pre-treated patients. Eligible patients had significantly better survival than non-eligible patients, median 29.2 versus 8.5 months (p = 0.0001). These results confirm that many patients from rural practices do not fulfill all mandatory trial eligibility criteria. However, eligible patients managed according to national guidelines had survival outcomes in line with published first-line trial results.

Cabozantinib and dastinib exert anti-tumor activity in alveolar soft part sarcoma.
Alveolar soft part sarcoma (ASPS) is an extremely rare metastatic soft tissue tumor with a poor prognosis for which no effective systemic therapies have yet been established. Therefore, the development of novel effective treatment approaches is required. Tyrosine kinases (TKs) are being increasingly used as therapeutic targets in a variety of cancers. The purpose of this study was to identify novel therapeutic target TKs and to clarify the efficacy of TK inhibitors (TKIs) in the treatment of ASPS.. To identify novel therapeutic target TKs in ASPS, we evaluated the antitumor effects and kinase activity of three TKIs (pazopanib, dasatinib, and cabozantinib) against ASPS cells using an in vitro assay. Based on these results, we then investigated the phosphorylation activities of the identified targets using western blotting, in addition to examining antitumor activity through in vivo assays of several TKIs to determine both the efficacy of these substances and accurate targets.. In cell proliferation and invasion assays using pazopanib, cabozantinib, and dasatinib, all three TKIs inhibited the cell growth in ASPS cells. Statistical analyses of the cell proliferation and invasion assays revealed that dasatinib had a significant inhibitory effect in cell proliferation assays, and cabozantinib exhibited marked inhibitory effects on cellular functions in both assays. Through western blotting, we also confirmed that cabozantinib inhibited c-MET phosphorylation and dasatinib inhibited SRC phosphorylation in dose-dependent fashion. Mice that received cabozantinib and dasatinib had significantly smaller tumor volumes than control animals, demonstrating the in vivo antitumor activity of, these substances.. Our findings suggest that cabozantinib and dasatinib may be more effective than pazopanib against ASPS cells. These in vitro and in vivo data suggest that c-MET may be a potential therapeutic target in ASPS, and cabozantinib may be a particularly useful therapeutic option for patients with ASPS, including those with pazopanib-resistant ASPS.
