Safety of Vinflunine in Patients with Advanced Urothelial Carcinoma Refractory to Platinum-based Chemotherapy: A Prospective Pilot Study. Curr Drug Saf 2018; 14:31-36. [PMID: 30277164 DOI: 10.2174/1574886313666181001120752] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2018] [Revised: 09/24/2018] [Accepted: 09/25/2018] [Indexed: 11/22/2022]
Abstract
BACKGROUND Several single chemotherapeutic agents have been evaluated as the second-line treatment of advanced urothelial carcinoma. Despite encouraging efficacy outcomes, toxicity has often led to dose modifications or discontinuation. We aimed to assess the safety of vinflunine in a particular population of advanced transitional cell carcinoma of urothelium (TCCU), that were exposed to the previous toxicity of chemotherapy. METHODS This is an open-label, prospective, single-center pilot study to evaluate the response rate and safety profile of vinflunine in patients with advanced TCCU. It was planned to enroll 25 evaluable patients. Eligible patients are those with progressive disease after first-line platinum-based regimen for advanced or metastatic disease. RESULTS The study was prematurely closed due to two sudden deaths that were judged by the review board as treatment-related. Only ten patients were evaluated and received at least one cycle of vinflunine. All but one were male and seven underwent radical surgery. Eight had a distant metastasis (mainly lung and/or liver). Disease control rate was 40%, four patients had a partial response with median duration of response of 3.5 months. The median overall survival was 3.2 months (95% CI:1.67- 4.73). There were three serious adverse events namely two sudden deaths and one grade 4 thrombocytopenia. Nine grade 3/4 adverse events occurred. The most common all-grade adverse events were fatigue (50%), constipation (40%) and vomiting (40%). Moreover, grade 3 fatigue occurred in 30% of patients. Only one patient, who achieved PR for 5 months, was fit to receive further cytotoxic chemotherapy. CONCLUSION The activity of vinflunine in advanced urothelial carcinoma came at the expense of its safety. The use of vinflunine has to be limited to the selected group of patients. However, this is a single institute experience in a limited number of patients.

Abstract
BACKGROUND Clinical trials in advanced/metastatic urothelial cancer have been difficult to perform. We review the current characteristics of randomized controlled trials (RCTs) and evaluate whether PFS could be a potential surrogate endpoint for overall survival (OS) in advanced/metastatic urothelial cancer. METHODS We identified trials by a systematic review of Medline, Embase, and the Cochrane Central Register of Controlled Trials from inception to April 2017. We included RCTs of patients with locally advanced/metastatic urothelial cancer that involved systemic therapy as an intervention, and those with reported hazards ratios (HRs) and corresponding 95% confidence intervals (CIs) for both OS and PFS, or provided Kaplan-Meier curves from which HRs and 95% CI could be calculated. The correlation coefficient between log of HRs for OS and PFS was calculated using linear regression weighted by sample size. RESULTS Forty eight trials that enrolled 7019 patients were included in the review and 24 RCTs were included in the surrogacy analysis. 27(56.3%) of identified 48 RCTs were phase II trials, and the median sample size was 107(range, 30-626) for all RCTs. The correlation coefficient between log HR for PFS and log HR for OS was 0.79 (95% CI, 0.58-0.91). The correlation coefficient increased to 0.87 (95% CI, 0.72-0.94) after excluding the only trial with immune checkpoint inhibitor. Multiple sensitivity analyses did not change the results..aph."/> CONCLUSIONS: PFS is strongly correlated with OS in trials of advanced/metastatic urothelial cancer assessing the treatment benefit of new drugs And PFS warrants further exploration as a surrogate endpoint in clinical trial datasets.

Abstract
The SIU (Société Internationale d'Urologie)-ICUD (International Consultation on Urologic Diseases) working group on systemic therapy for metastatic bladder cancer has summarized the most recent findings on the aforementioned topic and came to conclusions and recommendations according to the evidence published. In Europe and the United States, treatment for metastatic UC has changed a great deal recently, mainly involving a move from chemotherapy to immune checkpoint blockers. This is particularly true in platinum-refractory disease, where supportive randomized data exist. Five checkpoint blockers have been approved in this setting by the FDA: avelumab, atezolizumab, durvalumab, nivolumab, and pembrolizumab. Nivolumab, pembrolizumab, and atezolizumab have been approved in Europe.

Abstract
Background The objective of this study was to evaluate the efficacy of a combination of gemcitabine and docetaxel (GD) as a second-line treatment for elderly patients with metastatic urothelial carcinoma (mUC). Patients and methods A total of 122 patients with mUC who were previously treated with platinum-based chemotherapy received second-line GD therapy from July 2010 to June 2016. This consisted of 800 mg/m2 gemcitabine and 40 mg/m2 docetaxel on days 1 and 8 in each 21-day cycle. Using pooled cumulative data, we divided patients into the following three groups based on age: <65 years (Group A), from 65 to 74 years (Group B), and ≥75 years (Group C), and then the data were retrospectively analyzed. All patients were evaluated for treatment-related toxicities and assessed at every cycle by imaging studies. Kaplan-Meier curves were used for survival and recurrence analyses. Furthermore, potential prognostic factors for progression-free survival (PFS) and overall survival (OS) were assessed via univariate and multivariate Cox regression analyses. Results The median follow-up period was 8.2 months (range: 2.1-100). The median number of treatment cycles was three (range: 1-16) in Group A, three (1-15) in Group B, and two (1-11) in Group C. The objective response rate was not significantly different between the three groups. In addition, PFS and OS from the start of second-line GD therapy were also not significantly different. According to univariate and multivariate analyses of the second-line GD-treated cohort, a good performance status was the only prognostic factor for PFS and OS. In Group C, myelosuppression including predominant neutropenia and anemia, fatigue, and nausea were the main common adverse events. However, the incidence of neutropenia and a reduction in platelets were not significantly different between the three groups. Treatment-related deaths did not occur in this study. Conclusion In this study, GD combination therapy as a second-line treatment for mUC resulted in favorable tumor responses and few treatment-related toxicities, even among elderly patients.

Abstract
Objectives The objective of the present study was to investigate the survival outcome and prognostic factors of metastatic urothelial carcinoma patients treated with second-line systemic chemotherapy in real-world clinical practice. Methods Overall, 114 patients with metastatic urothelial carcinoma undergoing second-line systemic chemotherapy were included in this retrospective analysis. The dominant second-line chemotherapy was a paclitaxel-based combination regimen (60%, 68/114). We assessed the progression-free survival and overall survival times using the Kaplan–Meier method. The Cox proportional hazards model was applied to identify the factors affecting overall survival. Results The median progression-free survival and overall survival times were 4 and 9 months, respectively. In the multivariate analysis, an Eastern Cooperative Oncology Group performance status score greater than 0 at presentation, C-reactive protein level ≧1 mg/dl and poor response to prior chemotherapy were adverse prognostic indicators. Patients with 0, 1, 2 and 3 of those risk factors had a median overall survival of 17, 12, 7 and 3 months, respectively. Conclusions The Eastern Cooperative Oncology Group performance status at presentation, C-reactive protein level and response to prior chemotherapy were prognostic factors for metastatic urothelial carcinoma patients undergoing second-line chemotherapy. In the future, this information might help guide the choice of salvage treatment, such as second-line chemotherapy or immune checkpoint inhibitors, after the failure of first-line chemotherapy.

Abstract
The treatment of advanced metastatic urothelial carcinoma has recently evolved
with the approval of five checkpoint inhibitors. In the second-line setting, in
patients who have progressed on cisplatin-based chemotherapy, pembrolizumab,
atezolizumab, durvalumab, nivolumab and avelumab are United States Food and Drug
Administration (FDA) approved. In cisplatin-ineligible patients, atezolizumab
and pembrolizumab are the FDA-approved checkpoint inhibitors. Here we describe
the updated clinical efficacy of these checkpoint inhibitors in the treatment of
advanced urothelial carcinoma and then suggest how they can be sequenced in the
context of available chemotherapeutic options. For cisplatin-eligible patients,
platinum-based chemotherapy remains the standard first-line treatment. For
patients progressing on platinum-based therapy, phase III trials have been
performed comparing pembrolizumab and atezolizumab separately with standard
chemotherapy, and results favor the use of pembrolizumab.

Abstract
Immunotherapy represents a new hope for patients with advanced urothelial carcinoma (UC). However, to date, only one of two randomized studies showed a clear survival advantage with these treatments. Aimed to investigate the role of immune-checkpoint inhibitors in patients with platinum progressed metastatic UC we performed a systematic review and meta-analysis of clinical trials to evaluate the efficacy and activity, in terms of Overall Survival (OS) and Objective Response Rate (ORR). Immune checkpoint inhibitors have showed to improve OS compared to chemotherapy in unselected patients (HR 0.80, 95% CI 0.69-0.93, p = 0.003), while the difference was not significant in patients selected for PD-L1 expression (HR 0.72, 95% CI 0.48-1.09, p = 0.12). Pooled probability of response was 0.18 (95% CI 0.16-0.20) in unselected patients and 0.27 (95% CI 0.25-0.32) in PD-L1 selected patients. Immunotherapy results in a significant survival advantage in PD-L1 unselected patients suggesting that PD-L1 expression may not be a reliable marker in previously platinum treated patients.

Abstract
Immune checkpoint inhibitors (ICI) have emerged as a novel therapeutic strategy that achieves significant clinical benefit in several tumor types, including urothelial cancer. Overall, these agents have shown objective response rates of around 20% to 23%, which indicates that a significant proportion of patients do not benefit from immunotherapy when given as monotherapy. Moreover, despite an initial response to therapy and an improvement in the median duration of response compared with chemotherapy, still only half of the patients develop long-term maintained remissions. Active research is ongoing in several fields, aiming to increase the number of patients that benefit from ICI, and this research is largely based on the development of biomarkers for personalized immunotherapy and novel combinations of ICI with other agents. This article will review ongoing efforts to develop combinations of ICI with other therapeutic strategies in patients with urothelial cancer, including chemotherapy, targeted agents, other immunotherapy strategies, and radiotherapy.

Abstract
CONTEXT A number of PD-1/PD-L1 inhibitors have recently been approved for use in patients with locally advanced or metastatic urothelial carcinoma (UC) on the basis of results from several clinical trials. OBJECTIVE To review the evidence from these trials and consider what it means for the use of these drugs in first-line and post-platinum settings in real-life clinical practice. EVIDENCE ACQUISITION PubMed was searched for full reports of clinical trials of single-agent PD-1/PD-L1 inhibitors in advanced UC. Twelve publications were included. EVIDENCE SYNTHESIS Responses to PD-1/PD-L1 inhibitors appear to be durable but are only achieved in 17-26% of patients. These drugs offer different toxicity and efficacy profiles to standard chemotherapy regimens. This should be considered when choosing a treatment strategy for each patient. CONCLUSIONS PD-1/PD-L1 inhibitors represent a major step forward in the management of advanced UC, although several questions remain regarding their optimal use in routine clinical practice. A validated predictive biomarker of response is yet to be defined, and this is perhaps the most significant unmet need for currently available drugs. PATIENT SUMMARY We reviewed the results from clinical trials that investigated how well certain types of anticancer drugs called PD-1/PD-L1 inhibitors worked in patients with bladder cancer. We found that more research is required to identify (1) the factors that might predict which patients with bladder cancer will respond to PD-1/PD-L1 inhibitors and (2) the optimum duration of treatment with these drugs.

Abstract
Cancer still represents a "nightmare" worldwide, causing annually millions of victims. Several antiproliferative molecules are currently used as drugs market and offer a pharmaceutical opportunity for attenuating and treating tumor manifestations. In this context, natural sources have a relevant role, since they provide the 60% of currently-used anticancer agents. Among the numerous natural products, acting via different mechanisms of action, microtubule-targeting agents (MTAs) have a high therapeutic potential, since they disrupt the abnormal cancer cell growth, interfering with the continuous mitotic division. Vinca alkaloids (VAs) are the earliest developed MTAs and approved for clinical use (Vincristine, Vinblastine, Vinorelbine, Vindesine, and Vinflunine) as agents in the treatment of hematological and lymphatic neoplasms. Here, we review the state-of-art of VAs, discussing their mechanism of action and pharmacokinetic properties and highlighting their therapeutic relevance and toxicological profile. Additionally, we briefly disclosed the technological approaches faced so far to ameliorate the pharmacological properties, as well as to avoid the drug resistance. Lastly, we introduced the recent advances in the discovery of new derivatives.

Abstract
Platinum-based combination chemotherapy has been the standard of care in the first-line treatment of metastatic urothelial carcinoma (mUC). Treatment of metastatic disease following progression on platinum-based regimens has evolved significantly in the last few years. Clinical trials are currently ongoing to determine how best to use and sequence these treatments. In this minireview, we will review current first-line treatment options in both cisplatin fit and cisplatin unfit patients and advances in first- and second-line treatments including chemotherapy and immunotherapy. This review reports key findings from the clinical trials especially highlighting the importance of PD-1 and PD-L1 inhibitors in the treatment of bladder/urothelial carcinomas.

Abstract
Bladder cancer is the sixth most common cancer in the US and most tumors have urothelial (transitional cell) histology. Platinum-based chemotherapy has long been the standard of care in advanced disease, but long-term outcomes have largely remained poor. Since the peak incidence of bladder cancer is in the eighth decade of life and beyond, medical comorbidities may often limit the use of chemotherapy. Immune checkpoint inhibitors with their favorable toxicity profiles and notable antitumor activity have ushered in a new era in the treatment of advanced urothelial cancer (UC) with five agents targeting the PD-1/PD-L1 pathway being recently approved by the US Food and Drug administration. A plethora of clinical trials are ongoing in diverse disease settings, employing agents targeting PD-1/PD-L1 and related immune checkpoint pathways. While reactivating anti-tumor immunity, these agents may lead to a unique constellation of immune-related adverse events, which may warrant discontinuation of therapy and potential use of immunosuppression. Novel combinations with various treatment modalities and optimal sequencing of active therapies are being investigated in prospective clinical trials and retrospective registries. At the era of precision molecular medicine, and since patients do not respond uniformly to these agents, there is a growing need for identification and validation of biomarkers that can accurately predict treatment response and assist in patient selection. This review discusses current updates and future directions of immunotherapy in advanced UC.

Abstract
Aim: To determine which of the approved immune checkpoint inhibitors is the optimal treatment in metastatic urothelial bladder cancer. Methods & materials: Only the pivotal Phase III trials of second-line metastatic urothelial bladder cancer were included in this network meta-analysis. Results: This NMA included three pooled trials (NCT00315237, NCT02256436 and NCT02302807) of 1125 participants. Pembrolizumab was the only treatment with positive effect on overall survival compared with the best supportive care. The treatment discontinuation rates due to adverse events of the pembrolizumab and atezolizumab did not differ from that of the best supportive care. C onclusion: Our results confirmed the superiority of pembrolizumab in the management of metastatic urothelial bladder cancer.

Abstract
PURPOSE Over the past 3 decades, no major treatment breakthrough has been reported for advanced bladder cancer. Recent Food and Drug Administration (FDA) approval of five immune checkpoint inhibitors in the management of advanced bladder cancer represent new therapeutic opportunities. This review examines the available data of the clinical trials leading to the approval of ICIs in the management of metastatic bladder cancer and the ongoing trials in advanced and localized settings. METHODS A literature search was performed on PubMed and ClinicalTrials.gov combining the MeSH terms: 'urothelial carcinoma' OR 'bladder cancer', and 'immunotherapy' OR 'CTLA-4' OR 'PD-1' OR 'PD-L1' OR 'atezolizumab' OR 'nivolumab' OR 'ipilimumab' OR 'pembrolizumab' OR 'avelumab' OR 'durvalumab' OR 'tremelimumab'. Prospectives studies evaluating anti-PD(L)1 and anti-CTLA-4 monoclonal antibodies were included. RESULTS Evidence-data related to early phase and phase III trials evaluating the 5 ICIs in the advanced urothelial carcinoma are detailed in this review. Anti-tumour activity of the 5 ICIs supporting the FDA approval in the second-line setting are reported. The activity of PD(L)1 inhibitors in the first-line setting in cisplatin-ineligible patients are also presented. Ongoing trials in earlier disease-states including non-muscle-invasive and muscle-invasive bladder cancer are discussed. CONCLUSIONS Blocking the PD-1 negative immune receptor or its ligand, PD-L1, results in unprecedented rates of anti-tumour activity in patients with metastatic urothelial cancer. However, a large majority of patients do not respond to anti-PD(L)1 drugs monotherapy. Investigations exploring the potential value of predictive biomarkers, optimal combination and sequences are ongoing to improve such treatment strategies.

Abstract
The use of immunotherapy has revolutionized the management of patients with locally advanced, unresectable, and metastatic urothelial carcinoma (UC); however, platinum-based chemotherapy remains a therapeutic cornerstone both in localized muscle-invasive and advanced UC. There is still no predictive molecular biomarker with clinical utility to help guide treatment and select patients most likely to derive benefit from a particular therapeutic modality or regimen. However, recent research has further characterized the inherent biology and immunology landscapes of UC leading to the development of potential biomarkers and therapeutic targets that could be used upon further validation. Emerging interrogation of The Cancer Genome Atlas (TCGA) and other molecular profiling datasets has led to the identification of distinct molecular subtypes with diverse clinical behaviors with potential sensitivity to various therapies. It has also led to the discovery of multiple frequently altered genes and proteins that could lead to perturbation of intracellular signaling pathways and of the dynamic interactions between tumor cells, their "microenvironment", and the host "macro-environment". The advent of molecular profiling and deeper next-generation sequencing has the potential to change biomarker and "real time" drug sensitivity assessment, introducing and testing the premise of "precision oncology" and personalized medicine. Within this review, we summarize emerging biomarkers that may predict response to cisplatin-based chemotherapy, immunotherapy, emerging targeted therapies, and promising combination strategies. We also highlight a few examples of 'precision medicine' trials aiming to improve outcomes in UC. Since our review is not exhaustive we strongly recommend the readers to follow the continuously changing literature in the very interesting and dynamic field of UC.

Abstract
BACKGROUND A randomised study to assess the addition of apatorsen, an antisense oligonucleotide that inhibits Hsp27 expression, to docetaxel in patients with metastatic urothelial carcinoma (mUC) relapsed after prior platinum-based chemotherapy. METHODS Multicentre, phase II study with 1:1 randomisation to apatorsen (three loading doses at 600 mg intravenous followed by weekly doses) plus docetaxel (75 mg/m2 intravenous every 21 days) (A/D) or docetaxel alone. Overall survival (OS) was the primary end point with a P value <0.1 (one-sided) being positive. Progression-free survival (PFS), objective response rate (ORR), safety, and effect of Hsp27 levels on outcomes were secondary end points. RESULTS Patients randomised to A/D (n = 99) had improved OS compared to docetaxel alone (n = 101): HR: 0.80, 80% CI: 0.65-0.98, P = 0.0784, median 6.4 vs 5.9 months. PFS and ORR were similar in both arms. A/D had more incidence of sepsis and urinary tract infections. Patients with baseline Hsp27 levels <5.7 ng/mL had improved OS compared to those with levels ≥5.7 ng/mL. Patients with a decline or ≤20.5% increase in Hsp27 from baseline benefited more from A/D than those with >20.5% increase. CONCLUSIONS A/D met its predefined OS end point in patients with platinum-refractory mUC in this phase II trial. This trial is hypothesis generating requiring further study before informing practice.

Abstract
Advanced urothelial cancer (UC) is a lethal disease despite current advances in systemic therapy, including platinum chemotherapy combinations and immune checkpoint inhibition. Tumor angiogenesis is involved in UC growth and metastatic progression. Proangiogenic signaling through the VEGFR is a key process in UC with prognostic significance. Targeting of VEGFR2 with the monoclonal antibody ramucirumab has been tested in various different tumor types. In this review, we discuss the development of the drug in the context of its preclinical and clinical use with a focus on UC. Improvements in our ability to predict responses and resistance are key for maximizing its efficacy and selecting the most appropriate combinations with other active agents.

Abstract
AIMS Vinflunine is a novel tubulin-targeted inhibitor indicated as a single agent for the treatment of bladder cancers after failure of prior platinum-based therapy. Its pharmacokinetics (PK) and pharmacodynamics (PD) have been independently characterized through several phase I and phase II studies. However, no global pharmacometric analysis had been conducted as yet. METHODS Vinflunine concentrations and safety data from 18 phase I and phase II studies were used to conduct population PK and PK/PD analysis, using Nonmem. A four-compartment model was used to describe vinflunine PK and several covariates were tested to explain interindividual variability. In terms of PK/PD relationship, a semiphysiological population PK/PD model was applied to describe time course of absolute neutrophil counts (ANC) after vinflunine administration and logistic regression models were used to test the relationship between vinflunine exposure and toxicities. RESULTS Vinflunine clearance is explained by creatinine clearance, body surface area and combination with PEGylated doxorubicin, leading to a decrease from 28.2 to 25.3% of the interindividual variability. When vinflunine dose is decreased, simulations of ANC time course (via a semiphysiological model) after vinflunine administration show a risk of neutropenia grade 3-4 at cycle 2 always lower than when dose is delayed. As an example, for moderate renal impaired patients, the risk is 42.1% when vinflunine is dosed at 320 mg m-2 once every 4 weeks vs. 23.3% for 280 mg m-2 once every 3 weeks. CONCLUSIONS We propose for the first time a global comprehensive clinical pharmacological analysis for intravenous vinflunine that may help drive dose adjustment.

Abstract
In November 2016, the results of a phase III clinical trial with the protein cell death (PD)-1 inhibitor pembrolizumab for second-line treatment of metastatic urothelial carcinoma were published and showed an overall survival benefit in comparison with conventional chemotherapy with vinflunine, docetaxel, or paclitaxel. In a similar trial the PD-L1 antibody atezolizumab showed no significant benefit in comparison to chemotherapy in the subgroup of PD-L1-positive patients and, thus, missed its primary endpoint. For other PD-1/PD-L1 directed substances, large phase I/II trials reported data concerning response rates and overall survival. This substance class will most likely become the new treatment standard in second-line treatment of metastatic urothelial cancer. Currently, PD-1/PD-L1 inhibitors are also being tested within randomized phase III trials for first-line treatment using different approaches either as a monotherapy or a combination with conventional chemotherapy or cytotoxic T‑lymphocyte-associated protein (CTLA)-4 inhibitors. Whereas data from single-arm phase II clinical trials have already been published, preliminary phase III data are expected in 2018.

Abstract
PURPOSE OF REVIEW Advanced urothelial carcinoma (aUC) has long been treated preferably with cisplatin-based chemotherapy, but many patients are cisplatin-ineligible whereas for those who progress on a platinum-based regimen treatment options are limited. We review key recent data regarding immune checkpoint inhibitors that are changing this treatment landscape. RECENT FINDINGS Since May 2016, five different agents targeting the PD-1/PD-L1 pathway (atezolizumab, pembrolizumab, nivolumab, avelumab, durvalumab) have received FDA approval for the treatment of aUC in the platinum-refractory setting, while pembrolizumab and atezolizumab are FDA-approved for cisplatin-ineligible patients in the first-line setting. Clinical outcomes and safety profiles of these agents appear relatively comparable across separate trials; however, only pembrolizumab is supported by level I evidence from a large randomized phase III trial showing overall survival benefit over conventional cytotoxic salvage chemotherapy in the platinum-refractory setting. Pembrolizumab has the highest level of evidence in platinum-refractory aUC, whereas pembrolizumab and atezolizumab have comparable level of evidence in the frontline setting in cisplatin-ineligible patients. Ongoing research is evaluating novel agents, various rational combinations, and sequences, as well as predictive and prognostic biomarkers.

Abstract
INTRODUCTION Optimal end points in phase 2 trials evaluating salvage therapy for metastatic urothelial carcinoma are necessary to identify promising drugs, particularly immunotherapeutics, where response and progression-free survival may be unreliable. We developed a nomogram using data from phase 2 trials of historical agents to estimate the 12-month overall survival (OS) for patients to which observed survival of nonrandomized data sets receiving immunotherapies could be compared. PATIENTS AND METHODS Survival and data for major prognostic factors were obtained from phase 2 trials: hemoglobin, performance status, liver metastasis, treatment-free interval, and albumin. A nomogram was developed to estimate 12-month OS. Patients were randomly allotted to discovery:validation data sets in a 2:1 ratio. Calibration plots were constructed in the validation data set and data bootstrapped to assess performance. The nomogram was tested on external nonrandomized cohorts of patients receiving pemetrexed and atezolizumab. RESULTS Data were available from 340 patients receiving sunitinib, everolimus, docetaxel + vandetanib, docetaxel + placebo, pazopanib, paclitaxel, or docetaxel. Calibration and prognostic ability were acceptable (c index = 0.634; 95% confidence interval [CI], 0.596-0.652). Observed 12-month survival for patients receiving pemetrexed (n = 127, 23.5%; 95% CI, 16.2-31.7) was similar to nomogram-predicted survival (19%; 95% CI, 16.5-21.5; P > .05), while observed results with atezolizumab (n = 403, 39.0%; 95% CI, 34.1-43.9) exceeded predicted results (24.6%; 95% CI, 23.4-25.8; P < .001). CONCLUSION This nomogram may be a useful tool to interpret results of nonrandomized phase 2 trials of salvage therapy for metastatic urothelial carcinoma by assessing the OS contributions of drug intervention independent of prognostic variables.

Abstract
An urgent need exists to improve the outcomes of patients with muscle-invasive bladder cancer (MIBC), and especially of those with metastatic disease. Treatments that enhance antitumour immune responses - such as immune-checkpoint inhibition - provide an opportunity to do this. Despite initial success, durable response rates in patients with advanced-stage MIBC treated with novel inhibitory antibodies targeting programmed cell death protein 1 (PD-1) or its endogenous ligand programmed cell death 1 ligand 1 (PD-L1) remain low. Radiotherapy is part of the management of bladder cancer in many patients. Evidence that radiotherapy has immunogenic properties is now available, but radiotherapy-induced immune responses are often negated by immunosuppression within the tumour microenvironment. Anti-PD-1 or anti-PD-L1 antibodies might enhance radiotherapy-induced antitumour immunity. This effect has been demonstrated in preclinical models of bladder cancer, and clinical trials involving this approach are currently recruiting. Combination treatment strategies provide an exciting opportunity for urological oncologists to not only improve the chances of cure in patients undergoing radical treatment for MIBC, but also to increase long-term response rates in those with metastatic disease.

Abstract
Immunotherapy with programmed cell death 1/ligand 1 (PD-1/PD-L1) checkpoint inhibitors has expanded a previously limited pool of effective treatment options for patients with metastatic urothelial carcinoma, particularly those with recurring or refractory disease and those who are ineligible for cisplatin. This review reports key findings from completed and ongoing clinical trials that highlight the potential of PD-1/PD-L1 blockade in urothelial carcinoma. A literature search was performed of PubMed, Embase, ClinicalTrials.gov, and selected annual congress abstracts. Prospective studies, reviews, editorials, and descriptions of ongoing anti-PD-1/PD-L1 studies in bladder cancer were included. Anti-PD-1/PD-L1 monoclonal antibodies have shown efficacy and safety across patient subgroups with urothelial carcinoma, including those with poor prognostic factors. Efficacy was similar across different anti-PD-1/PD-L1 agents. Although these antibodies have demonstrated durable responses in a subset of patients with urothelial carcinoma, clinicians are currently unable to predict which patients may derive benefit from immune checkpoint blockade. Anti-PD-1/PD-L1 antibodies have shown favorable clinical activity and tolerability in patients with metastatic urothelial carcinoma refractory to platinum-based therapy or who are ineligible for cisplatin. The activity of PD-1/PD-L1 inhibitors is now also being studied as first-line monotherapy in cisplatin-eligible patients in combination with chemotherapy as maintenance therapy after first-line chemotherapy, and in earlier disease states, such as muscle-invasive and non-muscle-invasive bladder cancer. Better predictive tools to define target patient populations are needed, as are further investigations to define optimal combinations or sequencing of treatments.

A Real-World Data Study to Evaluate Treatment Patterns, Clinical Characteristics and Survival Outcomes for First- and Second-Line Treatment in Locally Advanced and Metastatic Urothelial Cancer Patients in Germany. J Cancer 2018; 9:1337-1348. [PMID: 29721042 PMCID: PMC5929077 DOI: 10.7150/jca.23162] [Citation(s) in RCA: 36] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2017] [Accepted: 12/30/2017] [Indexed: 12/02/2022] Open
Abstract
Background: Worldwide, urothelial carcinoma (UC) is a common cause of morbidity and mortality. In particular, the incidence of bladder cancer varies widely across Europe; Germany has the ninth highest international age-standardized incidence. For advanced UC or metastatic UC (mUC), platinum-based combination chemotherapy is the standard first-line (1L) treatment; however, there is wide heterogeneity of second-line (2L) treatments, ranging from vinflunine in parts of Europe to taxanes and other agents elsewhere in Europe, in the United States and globally. Limited data exist on treatment patterns and outcomes in patients with advanced UC or mUC in the routine clinical setting in Germany. The objective of this study was to describe clinical characteristics, treatment patterns and subsequent outcomes in this setting. Methods: This retrospective observational cohort analysis evaluated 1L and 2L treatment patterns and overall survival (OS) in patients aged ≥18 years with advanced UC or mUC (T4b, N2-3 and/or M1) at office-based urology and academic as well as nonacademic urology clinics throughout Germany between 1 November 2009 and 2 June 2016. Data were obtained through the GermanOncology database and additional treatment centers using similar electronic case report forms. Results: Among the 435 patients included in the analysis, 435 received 1L treatment and 125 received 2L treatment. Median age at start of 1L treatment was 69 years, 75% of patients were male, 75% were current or ex-smokers, 15% had hemoglobin <10 g/dL and 44% had creatinine clearance<60 mL/min/1.73; proportions were similar with 2L treatment. Cardiovascular disease was the most frequently reported comorbidity (65%), followed by diabetes (19%). Most patients (77%) received 1L platinum-based combination treatment (most commonly gemcitabine + cisplatin, 83%). Of those treated with 2L treatment, 66% received a single agent (most commonly vinflunine, 71%). Median OS (95% CI) with 1L treatment was 16.1 months (13.7-19.2) overall and 17.7 months (14.4-24.2) with 1L cisplatin + gemcitabine. In the 1L setting, 12-month OS was 61%, 24-month OS was 39% and 36-month OS was 26%. Median (95% CI) OS with 2L treatment was 9.2 months (5.5-11.6) overall and 5.9 months (4.1-12.6) with 2L vinflunine. In the 2L setting, OS rates for the same time periods were 40%, 22% and 8%, respectively. Median (95% CI) progression-free survival was 7 months (6.4-8.1) and 4 months (3.0-4.8), respectively, in the 1L and 2L settings. Objective response rates were 34% in the 1L setting and 14% in the 2L setting. No difference in OS by sex or smoking status was noted. Patients with or without renal impairment had a 12-month OS of 54% or 69%, respectively. OS at 12 months was 63% among patients with an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0 to 1 vs 53% among patients with an ECOG PS of ≥2. Cox regression analysis found no difference in OS between vinflunine and other 2L treatments (P = 0.69). Conclusions: This study provides a contemporary multicenter assessment of real-world treatment patterns and outcomes among palliatively treated patients with UC in Germany. The findings were generally consistent with the poor treatment outcomes observed globally, underscoring the need for effective 1L and 2L treatment for advanced UC or mUC.

Health-Related Quality-of-Life Analysis From KEYNOTE-045: A Phase III Study of Pembrolizumab Versus Chemotherapy for Previously Treated Advanced Urothelial Cancer. J Clin Oncol 2018; 36:1579-1587. [PMID: 29590008 DOI: 10.1200/jco.2017.76.9562] [Citation(s) in RCA: 80] [Impact Index Per Article: 13.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
Purpose In the phase III KEYNOTE-045 study ( ClinicalTrials.gov identifier: NCT02256436), pembrolizumab significantly prolonged overall survival compared with investigator's choice of chemotherapy in patients with previously treated advanced urothelial cancer. Here, we report the results of health-related quality-of-life (HRQoL) analyses from the KEYNOTE-045 trial. Patients and Methods Patients were randomly assigned 1:1 to pembrolizumab 200 mg or investigator's choice of docetaxel 75 mg/m2, paclitaxel 175 mg/m2, or vinflunine 320 mg/m2 administered intravenously every 3 weeks. Key prespecified HRQoL analyses were time to deterioration (TTD) and mean change from baseline to week 15 in European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 global health status/quality-of-life score. Results Of 542 patients who were randomly assigned, 519 were included in HRQoL analyses (pembrolizumab, n = 266; chemotherapy, n = 253). HRQoL compliance was > 95% at baseline and approximately 88% at week 15 for both groups. Pembrolizumab prolonged TTD in global health status/quality-of-life score compared with chemotherapy (median, 3.5 months v 2.3 months; hazard ratio, 0.72; nominal one-sided P = .004). Mean (95% CI) change from baseline to week 15 in global health status/quality-of-life score was 0.69 (-2.40 to 3.77) with pembrolizumab and -8.36 (-11.84 to -4.89) with chemotherapy (mean difference, 9.05 points; 95% CI, 4.61 to 13.50; nominal two-sided P < .001). Conclusion Pembrolizumab prolonged TTD in HRQoL compared with chemotherapy. Patients who were treated with pembrolizumab had stable or improved global health status/quality of life, whereas those who were treated with investigator's choice of chemotherapy experienced declines in global health status/quality of life. Combined with efficacy and safety outcomes, these data support pembrolizumab as standard of care for patients with platinum-refractory advanced urothelial cancer.

Abstract
Cytotoxic chemotherapy has been the mainstay of medical therapy for metastatic urothelial cancer. Currently, the gemcitabine/cisplatin regimen is widely used worldwide as the standard first-line medical treatment. Very recently, in 2017, pembrolizumab, a highly selective, humanized monoclonal IgG4κ isotype antibody against programmed death 1, was approved as a second-line treatment to be used after platina-based chemotherapy for metastatic urothelial cancer in Japan. Based on its promising anti-tumor efficacy and manageable safety profile as demonstrated in the phase III KEYNOTE-045 trial, pembrolizumab therapy is expected to be rapidly introduced for treating metastatic urothelial cancer in clinical practice. The paradigm of medical treatment for patients with metastatic UC is dramatically changing through the introduction of this and other immune-checkpoint inhibitors. In this article, we provide a brief overview of these immune-checkpoint inhibitors and a comprehensive summary of the use of cytotoxic chemotherapy for metastatic urothelial cancer, including ongoing clinical trials.

Abstract
INTRODUCTION Metastatic urothelial carcinoma (UC) remains an aggressive disease associated with limited treatment options and a reduced survival. In spite of this, the first-line treatment based on platinum-based combinations has remained virtually unchanged for the last 20-30 years. Similarly, before the advent of the immune checkpoint inhibitors, there were no FDA-approved drugs for second-line therapy. In the last few years, impressive signs of anti-tumor activity have been reported with several immunotherapy agents targeting the programmed cell death-1 (PD-1) pathway. Avelumab, a PD-1 ligand (PD-L1) inhibitor, is currently being investigated for the treatment of UC. Areas covered: This article will review the pharmacological characteristics of avelumab, the efficacy studies which led to its approval, its safety profile, as well as its place within the management of urothelial carcinoma with immunotherapy. For that matter, we undertook a literature review of all the studies assessing the pharmacology of avelumab and its efficacy within clinical trials. Expert commentary: Avelumab has shown promising antitumor activity and a manageable safety profile in patients with UC. Its dual mechanism of action, blocking the interaction between PD-L1 and PD-1 and promoting antibody-dependent cell-mediated cytotoxicity could potentially be of great interest since it could produce synergistic clinical efficacy.

Abstract
BACKGROUND Uro-oncological emergencies can be caused by the tumor, treatment complications, or non-oncological diseases. This review focuses on chemotherapy-associated emergencies, especially febrile neutropenia (FN), tumor lysis syndrome (TLS), and extravasations. AIM The goal is to provide an overview on the most relevant chemotherapy-associated emergencies and treatment methods. MATERIALS AND METHODS The ESMO (European Society of Medical Oncology), EORTC (European Organization for Research and Treatment of Cancer), and S3 guidelines were used for the preparation of this review and a PubMed search was performed for "febrile neutropenia", "extravasation", and "tumor lysis syndrome". A selection of the most relevant articles was included. RESULTS A comprehensive medical history and examination are prerequisite for optimal treatment of chemotherapy-associated emergencies. The following aspects are of special interest: the malignant disease (tumor proliferation rate and burden); the applied medication (e. g., risk of FN, tissue damaging potential); the physical condition of the patient; age and relevant concomitant diseases (e. g., cardiovascular disease). Based on the diagnosis and the individual risk profile, therapeutic procedures are initiated. Distinct complications require an interdisciplinary treatment strategy. CONCLUSION New treatment options such as checkpoint inhibitors complicate diagnosis and treatment of uro-oncological emergencies. Thus, improved diagnostic tools are required to draw the right conclusions in an emergency.

Abstract
INTRODUCTION Urothelial bladder cancer is one of the most predominant malignancies worldwide with a poor prognosis when presented at an advanced or metastatic stage. Improving the therapeutic landscape in this setting has been an unmet medical need. Palliative cisplatin-based chemotherapy is currently the standard of care in first line therapies, but many patients are ineligible and few alternative therapies exist. Moreover second-line chemotherapy has minimal activity. Recently, immune-checkpoint inhibitors have shifted the therapeutic armamentarium of bladder cancer and it is now necessary to redesign the therapeutic paradigm. Areas covered: In this article, we focus on the development of durvalumab and provide an overview of the safety, activity, efficacy and future perspectives of this drug in urothelial carcinoma. Expert commentary: Durvalumab is a well-tolerated drug and demonstrated major and durable response in advanced bladder cancer. Combinations with durvalumab will probably emerge as promising therapeutic strategies for the treatment of urothelial carcinoma. Further research efforts are needed to identify predictive biomarkers of response to immune-oncology agents.

Abstract
BACKGROUND Few options exist for patients with locally advanced or metastatic urothelial carcinoma after progression with platinum-based chemotherapy. We aimed to assess the safety and efficacy of atezolizumab (anti-programmed death-ligand 1 [PD-L1]) versus chemotherapy in this patient population. METHODS We conducted this multicentre, open-label, phase 3 randomised controlled trial (IMvigor211) at 217 academic medical centres and community oncology practices mainly in Europe, North America, and the Asia-Pacific region. Patients (aged ≥18 years) with metastatic urothelial carcinoma who had progressed after platinum-based chemotherapy were randomly assigned (1:1), via an interactive voice and web response system with a permuted block design (block size of four), to receive atezolizumab 1200 mg or chemotherapy (physician's choice: vinflunine 320 mg/m2, paclitaxel 175 mg/m2, or 75 mg/m2 docetaxel) intravenously every 3 weeks. Randomisation was stratified by PD-L1 expression (expression on <1% [IC0] or 1% to <5% [IC1] of tumour-infiltrating immune cells vs ≥5% of tumour-infiltrating immune cells [IC2/3]), chemotherapy type (vinflunine vs taxanes), liver metastases (yes vs no), and number of prognostic factors (none vs one, two, or three). Patients and investigators were aware of group allocation. Patients, investigators, and the sponsor were masked to PD-L1 expression status. The primary endpoint of overall survival was tested hierarchically in prespecified populations: IC2/3, followed by IC1/2/3, followed by the intention-to-treat population. This study, which is ongoing but not recruiting participants, is registered with ClinicalTrials.gov, number NCT02302807. FINDINGS Between Jan 13, 2015, and Feb 15, 2016, we randomly assigned 931 patients from 198 sites to receive atezolizumab (n=467) or chemotherapy (n=464). In the IC2/3 population (n=234), overall survival did not differ significantly between patients in the atezolizumab group and those in the chemotherapy group (median 11·1 months [95% CI 8·6-15·5; n=116] vs 10·6 months [8·4-12·2; n=118]; stratified hazard ratio [HR] 0·87, 95% CI 0·63-1·21; p=0·41), thus precluding further formal statistical analysis. Confirmed objective response rates were similar between treatment groups in the IC2/3 population: 26 (23%) of 113 evaluable patients had an objective response in the atezolizumab group compared with 25 (22%) of 116 patients in the chemotherapy group. Duration of response was numerically longer in the atezolizumab group than in the chemotherapy group (median 15·9 months [95% CI 10·4 to not estimable] vs 8·3 months [5·6-13·2]; HR 0·57, 95% CI 0·26-1·26). In the intention-to-treat population, patients receiving atezolizumab had fewer grade 3-4 treatment-related adverse events than did those receiving chemotherapy (91 [20%] of 459 vs 189 [43%] of 443 patients), and fewer adverse events leading to treatment discontinuation (34 [7%] vs 78 [18%] patients). INTERPRETATION Atezolizumab was not associated with significantly longer overall survival than chemotherapy in patients with platinum-refractory metastatic urothelial carcinoma overexpressing PD-L1 (IC2/3). However, the safety profile for atezolizumab was favourable compared with chemotherapy, Exploratory analysis of the intention-to-treat population showed well-tolerated, durable responses in line with previous phase 2 data for atezolizumab in this setting.

Abstract
BACKGROUND Atezolizumab (anti-programmed death-ligand 1) was approved in the USA, Europe, and elsewhere for treatment-naive and platinum-treated locally advanced/metastatic urothelial carcinoma (mUC). OBJECTIVE To report efficacy and safety from an atezolizumab expanded access study. DESIGN, SETTING, AND PARTICIPANTS This single-arm, open-label study enrolled 218 patients at 36 US sites. Key eligibility criteria included progression during/following ≥1 platinum-based chemotherapy for mUC or in perioperative setting (progression within 12 mo) and Eastern Cooperative Oncology Group performance status (ECOG PS) 0-2. INTERVENTION Patients received atezolizumab1200mg intravenously every 3 wk until loss of clinical benefit, unacceptable toxicity, consent withdrawal, decision to discontinue, death, atezolizumab commercial availability, or study closure. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Key end points reported herein included Response Evaluation Criteria in Solid Tumors v1.1 objective response rate and duration, disease control rate (DCR; response or stable disease), and safety. RESULTS AND LIMITATIONS All patients received prior systemic therapy (68% mUC; 27% adjuvant; and 26% neoadjuvant). At baseline, 57% of 214 treated patients had ECOG PS ≥1, 19% had hemoglobin <10g/dl, and 25% had liver metastases. Median treatment duration was 9 wk (interquartile range [IQR], 6-12 wk). Median follow-up duration was 2.3 mo (IQR, 1.6-3.4 mo) overall and 2.7 mo (IQR, 2.0-3.5 mo) in patients not known to have died. Seventeen of 114 evaluable patients (15%) had objective responses (16 ongoing at study termination). DCR was 49%. Treatment-related adverse events (mostly fatigue) occurred in 98 of 214 treated patients. CONCLUSIONS The benefit/risk profile of atezolizumab was consistent with that observed in previous studies, despite pretreatment and poor prognostic factors. These results suggest a potential role for atezolizumab in a broader patient range than typically eligible for phase 1-3 studies. PATIENT SUMMARY In this expanded access study, atezolizumab was active and tolerable in a range of patients with platinum-treated metastatic urothelial carcinoma.

Abstract
There is currently no standard treatment for metastatic urothelial cancer after failure of cisplatin-based therapy. The present retrospective study investigated the efficacy and safety of oxaliplatin plus 5-fluorouracil (5-FU) and leucovorin (LV) (FOLFOX) in locally advanced or metastatic urothelial cancer patients following cisplatin-based treatment. Thirty-three patients who had received one or two cisplatin-based regimens were treated with oxaliplatin (85 mg/m2) as a 2-h infusion on day 1, LV (200 mg/m2) as a 2-h infusion followed by bolus 5-FU (400 mg/m2) on day 1, or a 44-h continuous 5-FU (1,200 mg/m2) infusion. Patients were a mean of 67 years old with two involved organs. Metastases were mostly in the lung (43%), lymph nodes (51%) and liver (46%). Based on an intention-to-treat analysis, nine patients achieved a partial response, with an overall response rate of 27%. Eight (24%) patients had stable disease. Mean progression-free survival was 3 months and mean overall survival was 6.1 months. Toxicity was mild to moderate with grade 3 or 4 neutropenia, thrombocytopenia and neuropathy occurring in 5 (15%), 4 (12%) and 2 (6%) patients, respectively. This study demonstrated that oxaliplatin plus 5-FU/LV was a well-tolerated second-line regimen with moderate activity in patients pretreated with cisplatin-based therapeutics.

Abstract
Background Immunohistochemical PD-L1 assessment is currently used to identify responders towards checkpoint inhibitors although it is limited by inter-observer effects. Here, we conducted a multi-center round robin test to prove the possibility of assessing the PD-L1 status by gene expression to avoid inter-observer effects. Patients and methods Gene expression of PD-L1 was analyzed in a total of 294 samples (14 cases non-muscle invasive and muscle-invasive bladder cancer; MIBC) in seven centers by a RT-qPCR kit and compared with immunohistochemical scoring of three pathologists (DAKO, 22c3). Both assays were compared towards prognosis prediction in a cohort of 88 patients with MIBC. Results PD-L1 gene expression revealed very high inter center correlation (centrally extracted RNA: r = 0.68–0.98, p ≤ 0.0076; locally extracted RNA: r = 0.81–0.98, p ≤ 0.0014). IHC Inter-observer concordance was moderate to substantial for immune cells (IC), fair for combined IC/ tumor cell (TC) (IC: κ = 0.50–0.61; IC + TC: κ = 0.50), and fair for TC scoring (κ = 0.26–0.35). Gene expression assessment resulted in more positive cases (9/14 cases positive vs. 6/14 cases [IHC]) which could be validated in the independent cohort. Positive mRNA status was associated with significantly better overall and disease-specific survival (5-year OS: 50% vs. 26%, p = 0.0042, HR = 0.48; 5 year DSS: 65% vs. 40%, p = 0.012, HR = 0.49). The 1% IHC IC cut-off also revealed significant better OS (5 year OS: 58% vs. 31%, p = 0.036, HR = 0.62). Conclusion Gene expression showed very high inter-center agreement. Gene expression assessment also resulted in more positive cases and revealed better prognosis prediction. PD-L1 mRNA expression seems to be a reproducible and robust tool for PD-L1 assessment.

Safety and efficacy of temsirolimus as second line treatment for patients with recurrent bladder cancer. BMC Cancer 2018; 18:194. [PMID: 29454321 PMCID: PMC5816357 DOI: 10.1186/s12885-018-4059-5] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2017] [Accepted: 01/29/2018] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND Bladder cancer is the 7th cause of death from cancer in men and 10th in women. Metastatic patients have a poor prognosis with a median overall survival of 14 months. Until recently, vinflunine was the only second-line chemotherapy available for patients who relapse. Deregulation of the PI3K/AKT/mTOR pathway was observed in more than 40% of bladder tumors and suggested the use of mTOR as a target for the treatment of urothelial cancers. METHODS This trial assessed the efficacy of temsirolimus in a homogenous cohort of patients with recurrent or metastatic bladder cancer following first-line chemotherapy. Efficacy was measured in terms of non-progression at two months according to the RECIST v1.1 criteria. Based on a two-stage optimal Simon's design, 15 non-progressions out of 51 evaluable patients were required to claim efficacy. Patients were treated at a weekly dose of 25 mg IV until progression, unacceptable toxicities or withdrawal. RESULTS Among the 54 patients enrolled in the study between November 2009 and July 2014, 45 were assessable for the primary efficacy endpoint. A total of 22 (48.9%) non-progressions were observed at 2 months with 3 partial responses and 19 stable diseases. Remarkably, 4 patients were treated for more than 30 weeks. Fifty patients experienced at least a related grade1/2 (94%) and twenty-eight patients (52.8%) a related grade 3/4 adverse event. Eleven patients had to stop treatment for toxicity. This led to recruitment being halted by an independent data monitoring committee with regard to the risk-benefit balance and the fact that the primary objective was already met. CONCLUSIONS While the positivity of this trial indicates a potential benefit of temsirolimus for a subset of bladder cancer patients who are refractory to first line platinum-based chemotherapy, the risk of adverse events associated with the use of this mTOR inhibitor would need to be considered when such an option is envisaged in this frail population of patients. It also remains to identify patients who will benefit the most from this targeted therapy. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01827943 (trial registration date: October 29, 2012); Retrospectively registered.

Abstract
INTRODUCTION In patients with muscle invasive or Bacillus Calmette-Guérin refractory urothelial carcinoma of the urinary bladder (UCUB) radical cystectomy represents the standard of care. However, a proportion of patients experience disease progression, local recurrence and/or metastatic disease. Areas covered: This review provides an overview of available therapeutic strategies after radical cystectomy and examines ongoing clinical trials including cytotoxic chemotherapy and immunotherapy. Expert commentary: Cytotoxic chemotherapy offers limited benefit in UCUB patients. However, the recent introduction of immunotherapy provides new hope for durable responses or possibly complete cures.

Abstract
Vinflunine is the only cytotoxic agent tested as a second line therapy in transitional cell carcinoma of the urothelium in a phase III trial. It is not largely employed in clinical practice because of the high incidence of grade 3-4 toxicity. We evaluated efficacy and safety of Vinflunine at the dose of 280 mg/m2 every 3 weeks associated with primary prophylaxis with granulocyte growth factors and laxatives for patients progressed after platinum + Gemcitabine. Overall survival was 8.5 months, progression-free survival 4.33 months and response rate 25%, with disease control rate 57.2%. Grade III-IV neutropenia occurred in 10.7% of the patients, grade III-IV anemia and grade III thrombocytopenia in 10.7% and 7.2%, respectively. Among non haematological toxicity, grade I-II constipation was reported in 14.2% of the patients, without grade III-IV adverse events. No discontinuation for toxicity was observed. This study underlines that Vinfluinine at a dose of 280 mg/m2 associated with primary prophylaxis for neutropenia and constipation is effective and with a favorable toxicity profile.

Abstract
Urothelial carcinoma is the sixth most common malignancy in the US. While most patients present with non-muscle-invasive disease, many will develop recurrent disease including some progressing to muscle invasive metastatic cancer. Treatment outcomes have remained poor and stagnant for those with more advanced illness, with typical 5-year survival rates in the range of ≤15%. While first-line, platinum-based chemotherapy remains the current standard for those eligible, the recent incorporation of checkpoint inhibitors into the management of advanced bladder cancer has resulted in an expansion of treatment options for a difficult-to-treat disease. This review will discuss the historic standard treatment options, followed by the more recent evolving role immune therapy has in the management of bladder cancer.

Abstract
As research focus in oncology has recently shifted from oral targeted therapy to immunomodulation, the era of successful drug development in bladder cancer has just begun. This has led to unprecedented approval of five immunotherapeutic agents by regulatory agencies for metastatic bladder cancer within a span of 12 months. With an initial triumph of anti-programmed cell death-1 (anti-PD-1) and anti-programmed cell death ligand-1 (anti-PDL-1) drugs, ongoing efforts are aimed at identification and validation of new druggable immune targets to consolidate the initial gains. In this paper, we review the role of immunotherapy in the treatment of bladder cancer as well as the various emerging immunotherapeutic agents and their possible use in bladder cancer.

Abstract
Background A systematic review and meta-analysis of the use of systemic vinflunine (VIN) in the treatment of urothelial carcinoma (UC) was performed to evaluate its efficacy based on current available clinical data. Methods This review was prospectively registered at the International Prospective Register of Systematic Reviews, PROSPERO (registration CRD42016049294). Electronic databases including MEDLINE®, Embase®, Cochrane Central Register of Controlled Trials, and Web of Science were searched through December 2016. We performed a meta-analysis of the published data. Primary end points were progression-free survival (PFS) and overall survival (OS). Numerous secondary clinical outcomes were analyzed including response and toxicity data. Results We identified 382 publications, of which 35 met inclusion criteria for this review representing 29 unique studies. A total of 2,255 patients received VIN for the treatment of UC in the included studies. OS and PFS were analyzed in a pooled Kaplan–Meier analysis. Response data were available for 1,416 VIN-treated patients with random effects proportion of complete response in 1%, partial response in 18%, and overall response rate of 21%. Toxicity analysis revealed fatigue (40.1%), nausea (33.9%), constipation (34.1%), and alopecia (26.0%) as the most prevalent overall non-hematologic adverse events (AEs). Most prevalent grade 3–4 AEs were fatigue (10.2%), abdominal pain (8.2%), myalgias (2.5%), and nausea (2.3%). Most common hematologic AEs of all grades were anemia (56.6%), neutropenia (46.0%), thrombocytopenia (25.5%), and febrile neutropenia (6.6%). Grade 3–4 hematologic AEs had the following pooled rates: neutropenia, 24.6%; anemia, 10.2%; febrile neutropenia, 5.4%; and thrombocytopenia, 3.0%. Conclusion VIN has been explored as a combination first-line treatment as well as a single-agent second-line, third-line, and maintenance therapy for advanced and metastatic UC. In first-line treatment of UC, either as a maintenance agent after cisplatin or as a primary combination therapy, VIN may be a promising alternative to current treatments. Further studies are needed to compare first-line combination VIN regimens to the current standard of care in order to assess long-term survival outcomes. Second- and third-line VIN monotherapy does provide a proven, although limited, survival benefit in platinum-refractory patients.

Abstract
Background: Currently, a diagnosis of non-organ confined bladder cancer (NOCBCa) confers a grave prognosis. The mainstay of treatment consists of systemic chemotherapy. However, it must be recognized that NOCBCa is a heterogeneous disease state with important clinical distinctions. While surgical extirpation has traditionally been regarded as overly aggressive for all NOCBCa patients, its utility as part of a multimodal treatment strategy in various clinical scenarios has not been thoroughly investigated. Objective: To perform a review of the literature regarding the role of radical cystectomy and pelvic lymph node dissection (RC-LND) in the setting of NOCBCa. Methods: Medline, and Pubmed electronic database were queried for English language articles from January 1990 to Nov 2016 on RC-LND for cT4, lymph node positive, and metastatic urothelial cancer. NOCBCa was separated into four distinct clinical scenarios: 1. Locally advanced/unresectable disease (cT4bN0M0); 2. Occult pelvic nodal disease (pN+) (cTxN0M0 and pTxN1-3Mx); 3. Clinical node positive disease (cN+) (cTxN1-3M0); and 4. Distant metastatic disease (TxNxM1). Evidence for the role of RC-LND in each of these clinical scenarios was summarized. Results: cT4b may be more effectively treated by presurgical chemotherapy (PSC) than other forms of NOCBCa. Although clinical response predicted improved survival, surgical factors, such as surgical margin status may also play a role in determining outcomes. In well selected patients, 5-year CSS may reach 60% after consolidative RC-LND. Survival in patients found to have pathologic nodal metastases without PSC was dictated not only by the histologically verified metastatic nodal disease burden, but also by the meticulousness of the lymph node dissection. In these patients, adjuvant chemotherapy may improve survival. On the other hand, in patients undergoing RC-LND after PSC, pathologic complete response (pCR) was the strongest predictor of improved CSS. The results of population based studies have suggested a therapeutic role by consolidative RC-LND in both patients with cN+ and metastatic BCa (mBCa). For the cN+ population, 5-year OS was 31% in patients undergoing RC-LND after PSC vs. 14% in those receiving chemotherapy alone. Similarly, consolidative intensive local therapy improved OS by approximately 5 months in patients with mBCa. Metastasectomy has also been shown to be effective in small retrospective series and may especially be useful in patients with solitary pulmonary lesions. Conclusions: Extirpative treatment of the primary tumor may be an important step in the management of de novo NOCBCa. The current retrospective and population based studies have demonstrated improved survival outcomes in patients with NOCBCa following RC-LND, especially in those with favorable response to PSC. With the advent of minimally invasive surgery and the enhanced post-surgical recovery protocols, RC-LND has not only been demonstrated to be feasible, but also tolerable in the setting of advanced BCa. Well designed, prospective trials are needed to definitively assess the value of surgical extirpation for NOCBCa patients.

Abstract
INTRODUCTION Until recently, patients with locally advanced or metastatic urothelial carcinoma after progression on cisplatin-containing chemotherapy had limited systemic treatment options with no significant survival benefit and poor tolerability. Advances in the field of immunotherapy with the introduction of checkpoint inhibitors have led to paradigm shifts in the treatment of various malignancies. Areas covered: The current review will summarize the clinical evidence of checkpoint inhibitors in bladder cancer, with a focus on pembrolizumab. Expert commentary: Category 1 evidence indicates that the checkpoint inhibitor pembrolizumab improves overall survival in patients with locally advanced or metastatic urothelial carcinoma who progressed after or during cisplatin-containing therapy as compared to current standard of care chemotherapy. Phase 1 and 2 evidence also indicates that checkpoint inhibitors are active in first line in patients who are ineligible for cisplatin-containing chemotherapy.
