Abstract
BACKGROUND The benefit of immune checkpoint inhibitors (ICIs) for poor performance status patients with advanced urothelial carcinoma (UC) remains unknown. OBJECTIVE In the present sub-analysis of the ARON-2 study, we investigated the role of pembrolizumab for advanced UC patients with ECOG (Eastern Cooperative Oncology Group) performance status (ECOG-PS) 2. PATIENTS AND METHODS Patients aged ≥ 18 years with a cytologically and/or histologically confirmed diagnosis of advanced UC progressing or recurring after platinum-based therapy and treated with pembrolizumab between 1 January 2016 to 1 April 2024 were included. In this sub-analysis we focused on patients with ECOG-PS 2. RESULTS We included 1,040 patients from the ARON-2 dataset; of these, 167 patients (16%) presented an ECOG-PS 2. The median overall survival (OS) was 14.8 months (95% confidence interval (CI) 12.5-16.1) in the overall study population, 18.2 months (95% CI 15.8-22.2) in patients with ECOG-PS 0-1, and 3.7 months (95% CI 3.2-5.2) in subjects with ECOG-PS 2 (p < 0.001). The median progression-free survival (PFS) in the overall study population was 5.3 months (95% CI 4.3-97.1), 6.2 months (95% CI 5.5-97.1) in patients with ECOG-PS 0-1, and 2.8 months (95% CI 2.1-3.4) in patients with ECOG-PS 2. Among the latter, liver metastases and progressive disease during first-line therapy were significant predictors of OS at both univariate and multivariate analyses. For PFS, univariate and multivariate analyses showed a prognostic role for lung metastases, liver metastases, and progressive disease during first-line therapy. CONCLUSIONS This large real-world evidence study suggests the effectiveness of second-line pembrolizumab for mUC patients with poor performance status. The presence of liver metastases and progressive disease during first-line therapy is associated with worse clinical outcomes and, thus, should be taken into account when making treatment decisions in clinical practice.

Abstract
The treatment landscape for patients with advanced urothelial carcinoma continues to evolve. Enfortumab vedotin plus pembrolizumab has received Food and Drug Administration approval based on recent phase 3 trial data showing superior efficacy compared with first-line platinum-based chemotherapy; however, its distinct toxicity profile may make it less suitable for some patients, and availability in some countries may be limited by cost considerations. Consequently, platinum-based chemotherapy is expected to remain an important first-line treatment option. Choice of platinum regimen (cisplatin- or carboplatin-based) is informed by assessment of clinical characteristics, including performance status, kidney function, and presence of peripheral neuropathy or heart failure. For patients without disease progression after completing platinum-based chemotherapy, avelumab first-line maintenance treatment is recommended by international guidelines. For patients who have disease progression, pembrolizumab is the preferred approach. Additionally, following results from a recent phase 3 trial, nivolumab plus cisplatin-based chemotherapy has also received Food and Drug Administration approval and is an additional first-line treatment option for cisplatin-eligible patients. Later-line options for patients with advanced urothelial carcinoma, depending on prior treatment, may include enfortumab vedotin, erdafitinib (for patients with FGFR2/3 mutations or fusions/rearrangements), sacituzumab govitecan, and platinum rechallenge. For the small proportion of patients ineligible for any platinum-based chemotherapy (i.e., unsuitable for cisplatin or carboplatin), immune checkpoint inhibitor monotherapy with pembrolizumab or atezolizumab is a first-line treatment option, although approved agents vary between countries. In summary, this podcast discusses recent developments in the treatment landscape for advanced urothelial carcinoma, eligibility for platinum-based chemotherapy, potential first-line treatment options, and treatment sequencing.

Abstract
OBJECTIVES Immune checkpoint inhibitors and enfortumab vedotin have opened new avenues for sequential treatment strategies for locally advanced/metastatic urothelial carcinoma (la/mUC). In the pre-enfortumab vedotin era, many patients could not receive third-line treatment owing to rapid disease progression and poor general status. This study aimed to analyze real-world sequential treatment practices for la/mUC in Japan, with a focus on patients who do not receive third-line treatment. METHODS We analyzed data for 1023 la/mUC patients diagnosed between January 2020 and December 2021 at 54 institutions from a Japanese nationwide cohort. RESULTS At the median follow-up of 28.5 months, the median overall survival from first-line initiation for 905 patients who received systemic anticancer treatment was 19.1 months. Among them, 81% and 32% received second- and third-line treatment. Notably, 52% had their treatment terminated before the opportunity for third-line treatment. Multivariate logistic regression analysis revealed that low performance status (≥1), elevated neutrophil-to-lymphocyte ratio (≥3), and low body mass index (<21 kg/m2) at the start of first-line treatment were independent risk factors for not proceeding to third-line treatment (p = 0.0024, 0.0069, and 0.0058, respectively). In this cohort, 33% had one of these factors, 36% had two, and 15% had all three. CONCLUSIONS This study highlights the high frequency of factors associated with poor tolerance to anticancer treatment in la/mUC patients. The findings suggest the need to establish optimal sequential treatment strategies, maximizing efficacy within time and tolerance constraints, while concurrently providing strong supportive care, considering immunological and nutritional aspects.

Abstract
Urothelial carcinoma (UC) is a common cancer associated with a poor prognosis in patients with advanced disease. Platinum-based chemotherapy has remained the cornerstone of systemic anticancer treatment for many years, and recent developments in the treatment landscape have improved outcomes. In this review, we provide an overview of systemic treatment for UC, including clinical data supporting the current standard of care at each point in the treatment pathway and author interpretations from a UK perspective. Neoadjuvant cisplatin-based chemotherapy is recommended for eligible patients with muscle-invasive bladder cancer and is preferable to adjuvant treatment. For first-line treatment of advanced UC, platinum-eligible patients should receive cisplatin- or carboplatin-based chemotherapy, followed by avelumab maintenance in those without disease progression. Among patients unable to receive platinum-based chemotherapy, immune checkpoint inhibitor (ICI) treatment is an option for those with programmed death ligand 1 (PD-L1)-positive tumours. Second-line or later treatment options depend on prior treatment, and enfortumab vedotin is preferred after prior ICI and chemotherapy, although availability varies between countries. Additional options include rechallenge with platinum-based chemotherapy, an ICI, or non-platinum-based chemotherapy. Areas of uncertainty include the optimal number of first-line chemotherapy cycles for advanced UC and the value of PD-L1 testing for UC.

Abstract
Aim: To assess physician-reported treatment of metastatic bladder cancer in Japan. Methods: 76 physicians completed the CancerMPact® survey in July 2020, considering patients treated within 6 months. Results: Physicians treated a mean of 38.1 patients per month. Of cisplatin-eligible and -ineligible patients, 97.6 and 89.3%, respectively, received first-line platinum-based therapy, most commonly cisplatin plus gemcitabine (72.9%) and carboplatin plus gemcitabine (59.7%). 1.6 and 5.6% received first-line immune checkpoint inhibitors, respectively. 48.4 and 45.0%, respectively, progressed and received second-line therapy, most commonly with pembrolizumab (61.7%). Conclusion: In 2020, most patients with metastatic bladder cancer in Japan received first-line platinum-based chemotherapy; however, >50% received no subsequent treatment, highlighting the need for new treatment regimens to improve outcomes and maximize first-line treatment benefits.

Abstract
New approaches involving immune checkpoint inhibitors and antibody-drug conjugates prolong overall survival in patients with metastatic urothelial carcinoma. However, the access to such systemic therapy in clinical practice is suboptimal, and whether these agents improve overall survival in patients with metastatic urothelial carcinoma over time remains unclear. Hence, we investigated the overall survival trend from the initiation of first-line therapy with these agents to identify changes due to the medication and time of treatment initiation. We retrospectively evaluated 195 patients from a single center. They were treated with chemotherapy, pembrolizumab, or avelumab or enfortumab vedotin. The treatment was categorized into chemotherapy, pembrolizumab or avelumab/enfortumab vedotin period. The new agents prolonged overall survival from the start of first-line therapy. Furthermore, sequential treatment with these agents in real-world clinical practice has been reported to prolong overall survival. These study results will have major implications when a new first-line therapy is approved in the future.

Abstract
Subtype of urothelial carcinoma (SUC), defined here as urothelial carcinoma with any histologic subtype or divergent differentiation, is a clinically aggressive disease. However, the efficacy of enfortumab vedotin (EV) against SUC remains unclear. Hence, this study aimed to assess the oncological outcomes of patients with SUC treated with EV for metastatic disease. We retrospectively evaluated consecutive patients with advanced lower and upper urinary tract cancer who received EV after platinum-based chemotherapy and immune checkpoint blockade therapy at six institutions. The objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were compared between patients with pure urothelial carcinoma (PUC) and those with SUC. We identified 44 and 18 patients with PUC and SUC, respectively. Squamous differentiation was the most common subtype element, followed by glandular differentiation and sarcomatoid subtype. Although patients with SUC had a comparable ORR to those with PUC, the duration of response for SUC was short. Patients with SUC had poorer PFS than those with PUC; however, no significant difference was observed in OS. Multivariate analysis revealed that SUC was significantly associated with shorter PFS. Although the response of metastatic SUC to EV was similar to that of PUC, SUC showed faster progression than PUC.

Abstract
Results from JAVELIN Bladder 100 established avelumab (anti-PD-L1) first-line maintenance as the standard-of-care treatment for patients with advanced urothelial carcinoma (UC) that has not progressed with first-line platinum-based chemotherapy. We describe the design of JAVELIN Bladder Medley (NCT05327530), an ongoing phase II, multicenter, randomized, open-label, parallel-arm, umbrella trial. Overall, 252 patients with advanced UC who are progression-free following first-line platinum-based chemotherapy will be randomized 1:2:2:2 to receive maintenance therapy with avelumab alone (control group) or combined with sacituzumab govitecan (anti-Trop-2/topoisomerase inhibitor conjugate), M6223 (anti-TIGIT) or NKTR-255 (recombinant human IL-15). Primary end points are progression-free survival per investigator and safety/tolerability of the combination regimens. Secondary end points include overall survival, objective response and duration of response per investigator, and pharmacokinetics.

Abstract
Locally advanced or metastatic urothelial carcinoma (aUC) presents a significant challenge with high mortality rates. Platinum-based chemotherapy remains the established frontline standard of care, and a switch-maintenance strategy with immunotherapy has now emerged as a new standard for aUC patients without disease progression, following initial platinum therapy. Examining the treatment patterns is imperative, given the evolving therapeutic landscape. In this study, we conducted a retrospective medical chart review of 17 Canadian oncologists treating patients with aUC to assess unmet needs in Canadian aUC patient care. Data from 146 patient charts were analyzed, revealing important clinical insights about the management of aUC. A substantial proportion of patients (53%) presented with de novo metastatic disease, which was possibly influenced by pandemic-related care disruptions. Variability was evident in the cisplatin eligibility criteria, with a majority (70%) of oncologists utilizing a 50 mL/min threshold. Most favored four cycles of platinum-based chemotherapy to spare the bone marrow for future therapies and prevent patient fatigue. Notably, some eligible patients were kept under surveillance rather than receiving maintenance therapy, suggesting a potential gap in awareness regarding evidence-based recommendations. Furthermore, managing treatment-related adverse events was found to be one of the biggest challenges in relation to maintenance immunotherapy. In conclusion, our findings provide the first comprehensive overview of aUC treatment patterns in Canada following the approval of maintenance immunotherapy, offering insights into the decision-making process and underscoring the importance of evidence-based guidelines in aUC patient management.

Ther Adv Urol 2024; 16:17562872241249073. [PMID: 38779496 PMCID: PMC11110528 DOI: 10.1177/17562872241249073] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Accepted: 04/01/2024] [Indexed: 05/25/2024] Open
Abstract
Antibody-drug conjugates and bicycle toxin conjugates represent a tremendous advance in drug delivery technology and have shown great promise in the treatment of urothelial cancer. Previously approved systemic therapies, including chemotherapy and immunotherapy, are often impractical due to comorbidities, and outcomes for patients with advanced disease remain poor, even when receiving systemic therapy. In this setting, antibody-drug and bicycle toxin conjugates have emerged as novel treatments, dramatically altering the therapeutic landscape. These drugs harness unique designs consisting of antibody or bicycle peptide, linker, and cytotoxic payload with more targeted delivery than conventional chemotherapy, thus eliminating malignant cells while reducing systemic toxicities. Potential targets investigated in urothelial cancer include Nectin-4, TROP2, HER2, and EphA2. Initial clinical trials demonstrated efficacy in treatment of refractory advanced urothelial cancer, as well as improvement in quality of life. These initial studies led to FDA approval of two antibody-drug conjugates, enfortumab vedotin and sacituzumab govitecan. Moreover, antibody-drug and bicycle toxin conjugates are being studied in ongoing clinical trials in frontline treatment of advanced disease as well as for localized cancer. These studies highlight the potential for additional future therapies with novel targets, novel antibodies, cytotoxic and immunomodulatory payloads, and unique structural designs enhancing efficacy and safety. There is increasing evidence that combinations with other cancer therapies, especially immunotherapy, improve treatment outcomes. The combination of enfortumab vedotin and pembrolizumab was recently approved for first-line treatment of advanced urothelial carcinoma. Despite the great promise of these novel drugs, robust predictive biomarkers are needed to determine the patients who would maximally benefit. This review surveys the rationale and current state of the evidence for these new drugs and describes future directions actively being explored.

Nationwide Study of Real-World Treatment Patterns and Clinical Outcomes in Patients with Metastatic Urothelial Carcinoma in Hungary. Adv Ther 2023; 40:5475-5488. [PMID: 37831384 PMCID: PMC10611888 DOI: 10.1007/s12325-023-02694-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Accepted: 09/21/2023] [Indexed: 10/14/2023]
Abstract
INTRODUCTION Data describing real-world treatment patterns in patients with metastatic urothelial carcinoma (mUC) in Central-Eastern Europe are scarce, and data from Hungary have not been published. This retrospective, nationwide, real-world study investigated patient characteristics, treatment patterns, comorbidities, and clinical outcomes in patients with mUC in Hungary. METHODS Adults diagnosed with mUC from January 2016 through June 2021 were identified using the National Health Insurance Fund Administration database. Overall survival (OS) was estimated using the Kaplan-Meier method. RESULTS In total, 2523 patients with mUC were identified. Median follow-up was 7.1 months. Overall, 50% of patients received an identified systemic anticancer treatment; within this subgroup, first-line treatment was platinum-based chemotherapy (PBC) in 86%, non-PBC in 8%, and immune checkpoint inhibitor (ICI) in 6%. The proportion of patients receiving treatment increased from 41% in 2016 to 59% in 2020, driven by increased use of first-line PBC or first-line ICI treatment. Comorbidities were more common in patients receiving first-line ICI treatment vs PBC or non-PBC and in patients receiving carboplatin + gemcitabine vs cisplatin + gemcitabine. Overall, only 24% received a second-line treatment. Unadjusted median OS from the start of first-line treatment in the PBC, non-PBC, and ICI subgroups was 12.8, 7.5, and 6.3 months, respectively. Median OS from date of diagnosis in untreated patients was 7.8 months. OS comparisons adjusted for differences in baseline characteristics between subgroups could not be performed. CONCLUSION To our knowledge, this is the first study to assess treatment patterns in patients with mUC in clinical practice in Hungary, using the national health insurance database. Rates of first- and second-line treatment were consistent with those observed in other countries. Avelumab first-line maintenance treatment became available for reimbursement in Hungary in late 2022, after the study period. Given the evolving landscape of reimbursed treatments in Hungary, further analyses are warranted.

Abstract
Aim: To assess rates of no systemic treatment (NST), attrition across lines of therapy, and factors influencing treatment selection in patients with locally advanced or metastatic urothelial cancer (la/mUC). Methods: Systematic literature review to identify real-world studies reporting NST or attrition rates in la/mUC from 2017-2022 (including data reported since 2015). Results: Of 2439 publications screened, 29 reported NST rates, ranging from 40-74% in eight European-based studies, 14-60% in 12 US-based studies, and 9-63% in nine studies in other locations (meta-analysis estimate, 39%). Factors associated with NST or no second-line therapy included older age, female sex, poor performance status, poor renal function and distant metastases. Conclusion: A substantial proportion of patients with la/mUC do not receive guideline-recommended treatment.

Abstract
Urothelial carcinoma is a common malignancy that affects the urinary system, with bladder cancer being the most prevalent form. Although the management of early-stage disease has seen significant improvements, the treatment of locally advanced and metastatic urothelial carcinoma remains challenging. Over the past decade, there has been an explosion in the number of therapies available for the treatment of advanced disease, with immune checkpoint inhibitors and antibody-drug conjugates leading the way. Enfortumab vedotin is an antibody-drug conjugate that targets Nectin-4, a protein that is overexpressed in urothelial carcinoma cells. In clinical trials, it has shown promising outcomes for the treatment of advanced urothelial carcinoma that has progressed after chemotherapy or immunotherapy. The US Food and Drug Administration has granted expedited approval for enfortumab vedotin in the treatment of advanced urothelial carcinoma. This review provides an overview of the current and emerging treatments for urothelial carcinoma, with a particular focus on enfortumab vedotin. We discuss the mechanisms of action, clinical efficacy, safety, and ongoing research of enfortumab vedotin, along with the current landscape of other approved therapies and promising agents in development. The aim of this review is to provide a comprehensive and up-to-date summary of the available treatment options for urothelial carcinoma, including their limitations and future prospects.

Abstract
PURPOSE Cisplatin-based combination chemotherapy remains the standard of care for locally advanced or metastatic urothelial cancer (la/mUC); however, toxicity is substantial, responses are rarely durable, and many patients with la/mUC are ineligible. Each enfortumab vedotin and pembrolizumab have shown a survival benefit versus chemotherapy in UC, are not restricted by cisplatin eligibility, and warrant investigation as a first-line (1L) combination therapy in patients ineligible for cisplatin. METHODS In this ongoing phase Ib/II, multicenter, open-label study, 1L cisplatin-ineligible patients with la/mUC received enfortumab vedotin 1.25 mg/kg once daily on days 1 and 8 and pembrolizumab 200 mg (day 1) intravenously once daily in 3-week cycles. The primary end point was safety. Key secondary end points included confirmed objective response rate, duration of response (DOR), and overall survival (OS). RESULTS Forty-five patients received enfortumab vedotin plus pembrolizumab. The most common treatment-related adverse events (TRAEs) were peripheral sensory neuropathy (55.6%), fatigue (51.1%), and alopecia (48.9%). Twenty-nine patients (64.4%) had grade 3 or higher TRAEs; the most common were increased lipase (17.8%), maculopapular rash (11.1%), and fatigue (11.1%). One death (2.2%) was classified as a TRAE. The confirmed objective response rate after a median of nine cycles was 73.3% with a complete response rate of 15.6%. The median DOR and median OS were 25.6 months and 26.1 months, respectively. CONCLUSION Enfortumab vedotin plus pembrolizumab showed a manageable safety profile. Most patients experienced tumor shrinkage. The median DOR and median OS exceeding 2 years in a cisplatin-ineligible patient population make this a promising combination currently under investigation in a phase III study (ClinicalTrials.gov identifier: NCT04223856).

Abstract
INTRODUCTION While switch maintenance therapy is being increasingly investigated in solid tumors, it is a standard in only a few. We conducted a systematic review on switch maintenance therapy for metastatic urothelial carcinoma. EVIDENCE ACQUISITION In this systematic review, we conducted a literature search in PubMed and Cochrane databases up to 2021, based on PRISMA statement guidelines. One hundred and fifty eight articles were identified and after a three-step selection process and six articles, using different agents were included in evidence synthesis. The primary end points were effect on overall survival, progression free survival, safety and tolerability. EVIDENCE SYNTHESIS In the pre-immunotherapy era, targeted therapies like sunitinib, lapatinib and vinflunine were studied as switch maintenance therapy in metastatic urothelial carcinoma but did not show any overall survival benefit. Use of anti-PD-1/PD-L1 agents have shown promise as switch maintenance therapy; pembrolizumab showed improvement in progression free survival in a phase 2 trial and avelumab showed improvement in overall survival and progression free survival in the phase 3 JAVELIN Bladder 100 trial. CONCLUSION Immunotherapy with anti-PD-1/PD-L1 agents has emerged as an effective switch maintenance strategy in patients with metastatic urothelial carcinoma. Intensification of the immunotherapy backbone in this setting can potentially further enhance outcomes. Emerging evidence shows a potential role of Poly (ADP-ribose) polymerase (PARP) inhibitors in this setting as well. Results from ongoing and planned studies will help us understand which switch maintenance approaches would be most effective for improving outcomes in metastatic urothelial carcinoma.

Abstract
CONTEXT Platinum-based combination chemotherapy is the standard treatment for advanced or metastatic urothelial carcinoma (AMUC). However, data comparing the efficacy of different platinum agents are limited. OBJECTIVE This review aimed to assess the efficacy of carboplatin as a first-line treatment for AMUC using phase 3 randomized trial data. EVIDENCE ACQUISITION Multiple databases were searched for articles published until August 2021. Studies that compared overall survival (OS), complete response (CR), and objective response rates (ORRs) in chemotherapy-eligible patients with AMUC were deemed eligible. EVIDENCE SYNTHESIS Four studies were included. Compared with immune checkpoint inhibitor (ICI) monotherapy, neither cisplatin- nor carboplatin-based chemotherapy was associated with significant OS (hazard ratio [HR]: 0.97, 95% confidence interval [CI]: 0.85-1.11, p = 0.64 and HR: 0.90, 95% CI: 0.78-1.04, p = 0.16, respectively) and CR (odds ratio [OR]: 1.16, 95% CI: 0.70-1.92, p = 0.57 and OR: 0.89, 95% CI: 0.52-1.53, p = 0.67, respectively benefits, while both were associated with a favorable ORR (OR: 0.54, 95% CI: 0.40-0.74, p < 0.001 and OR: 0.58, 95% CI: 0.42-0.80, p < 0.001, respectively). A network meta-analysis (NMA)-based indirect comparison between carboplatin and cisplatin revealed that while cisplatin was slightly better than carboplatin in terms of OS, CR, and ORR, no significant difference was noted. CONCLUSIONS Cisplatin- and carboplatin-based chemotherapies offer similar OS/CR benefits to ICI monotherapy and elicit a greater ORR than ICI monotherapy. Moreover, our NMA demonstrated that both cisplatin- and carboplatin-based chemotherapy have a similar efficacy in terms of OS, CR, and ORR. Given that carboplatin-based chemotherapy is shown to be more effective in contemporary series than in historical controls, it is strongly recommended that carboplatin be re-examined for its value in the era of ICIs and beyond. PATIENT SUMMARY Cisplatin- as well as carboplatin-based chemotherapy is as effective as immune checkpoint inhibitors in terms of survival and eliciting a positive response. It is currently believed that cisplatin provides greater benefits than carboplatin; this requires re-evaluation.

Abstract
Despite a high disease burden, real-world data on treatment patterns in patients with unresectable locally advanced or metastatic urothelial carcinoma (la/mUC) in Canada are limited. This retrospective, longitudinal cohort study describes treatment patterns and survival in a population of patients with de novo unresectable la/mUC from Alberta, Canada, diagnosed between 1 January 2015 and 31 December 2019, followed until mid-2020. The outcomes of interest were systemic therapy treatment patterns and overall survival (OS). Of 206 patients, most (65.0%, n = 134) did not receive any systemic therapies. Of 72 patients (35.0%) who received first-line systemic therapy, the median duration of treatment was 2.8 months (IQR 3.3). Thirty-five patients (48.6% of those who received first-line therapy) received subsequent second-line therapy, for a median of 3.0 months (IQR 3.3). In all patients (n = 206), the median OS from diagnosis was 5.3 months (95% CI, 4.5-7.0). In patients who received treatment, the median OS from the initiation of first-line and second-line systemic therapy was 9.1 (6.4-11.6) and 4.6 months (3.9-19.2), respectively. The majority of patients did not receive first-line systemic therapy, and, in those who did, survival outcomes were poor. This study highlights the significant unmet need for safe and efficacious therapies for patients with la/mUC in Canada.

Abstract
Erdafitinib received accelerated approval on April 12, 2019, for patients with metastatic or locally advanced urothelial carcinoma with susceptible fibroblast growth factor receptor (FGFR) 3 or FGFR2 genetic alterations and who have progressed during or following at least one platinum-based chemotherapy. It thus became the first-ever targeted therapy to receive accelerated FDA approval for metastatic bladder cancer. In the BLC2001 trial, erdafitinib demonstrated an overall response rate of 40% in patients with urothelial carcinoma. Common adverse events include hyperphosphatemia and retinopathy and require regular monitoring. While the increase in serum phosphate levels has been determined to be a pharmacodynamic marker of response, further interrogation of other clinical, genomic, and transcriptomic biomarkers is warranted. Results of the ongoing Phase III trial, THOR, which is comparing erdafitinib to the standard of care (chemotherapy or immunotherapy), are expected to confer full approval. Establishing guidelines for optimal erdafitinib sequencing with immunotherapy and other approved targeted therapies (enfortumab vedotin and sacituzumab govitecan) remains an unmet need.

Abstract
INTRODUCTION Despite rapid advances in the treatment landscape of urothelial cancer, there is a substantial unmet need for safe and effective therapies for patients with locally advanced and metastatic urothelial cancer. Sacituzumab govitecan (SG) is an antibody-drug conjugate, consisting of a Trop-2 directed monoclonal antibody linked to SN-38, the active metabolite of irinotecan. Trop-2 is a glycoprotein overexpressed in various carcinomas, including urothelial carcinomas. AREAS COVERED We review the available data on SG, including mechanism of action, pharmacology, efficacy, safety, and clinical studies regarding locally advanced or metastatic urothelial cancer. EXPERT OPINION SG performed well in the TROPHY-U-01 phase II trial with an objective response rate of 27%. The most common adverse effects were diarrhea, nausea, fatigue, alopecia, and neutropenia, with the most common grade ≥ 3 treatment-related AEs being neutropenia, leukopenia, anemia, diarrhea, and febrile neutropenia. However, these effects were managed effectively with supportive care. SG currently has an accelerated approval for patients with locally advanced or metastatic urothelial cancer who have received platinum-based chemotherapy and either programmed cell death receptor-1 (PD-1) or programmed death-ligand 1 (PD-L1) inhibitor. Several studies are evaluating SG in urothelial cancers as single-agent or in combination with other agents.

APOBEC Mutational Signature and Tumor Mutational Burden as Predictors of Clinical Outcomes and Treatment Response in Patients With Advanced Urothelial Cancer. Front Oncol 2022; 12:816706. [PMID: 35321431 PMCID: PMC8935010 DOI: 10.3389/fonc.2022.816706] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Accepted: 02/10/2022] [Indexed: 12/21/2022] Open
Abstract
Introduction Tumor mutational burden (TMB) and APOBEC mutational signatures are potential prognostic markers in patients with advanced urothelial carcinoma (aUC). Their utility in predicting outcomes to specific therapies in aUC warrants additional study. Methods We retrospectively reviewed consecutive UC cases assessed with UCSF500, an institutional assay that uses hybrid capture enrichment of target DNA to interrogate 479 common cancer genes. Hypermutated tumors (HM), defined as having TMB ≥10 mutations/Mb, were also assessed for APOBEC mutational signatures, while non-HM (NHM) tumors were not assessed due to low TMB. The logrank test was used to determine if there were differences in overall survival (OS) and progression-free survival (PFS) among patient groups of interest. Results Among 75 aUC patients who had UCSF500 testing, 46 patients were evaluable for TMB, of which 19 patients (41%) had HM tumors and the rest had NHM tumors (27 patients). An additional 29 patients had unknown TMB status. Among 19 HM patients, all 16 patients who were evaluable for analysis had APOBEC signatures. HM patients (N=19) were compared with NHM patients (N=27) and had improved OS from diagnosis (125.3 months vs 35.7 months, p=0.06) but inferior OS for patients treated with chemotherapy (7.0 months vs 13.1 months, p=0.04). Patients with APOBEC (N=16) were compared with remaining 56 patients, comprised of 27 NHM patients and 29 patients with unknown TMB, showing APOBEC patients to have improved OS from diagnosis (125.3 months vs 44.5 months, p=0.05) but inferior OS for patients treated with chemotherapy (7.0 months vs 13.1 months, p=0.05). Neither APOBEC nor HM status were associated with response to immunotherapy. Conclusions In a large, single-institution aUC cohort assessed with UCSF500, an institutional NGS panel, HM tumors were common and all such tumors that were evaluated for mutational signature analysis had APOBEC signatures. APOBEC signatures and high TMB were prognostic of improved OS from diagnosis and both analyses also predicted inferior outcomes with chemotherapy treatment.

Clinical evidence and insights supporting the use of avelumab first-line maintenance treatment in patients with advanced urothelial carcinoma in the Asia-Pacific region. Asia Pac J Clin Oncol 2022; 18:e191-e203.

Abstract
Until recently, international and Asia-specific guidelines for advanced urothelial carcinoma (UC) recommended first-line (1L) platinum-based chemotherapy, followed by second-line (2L) anti-PD-1 or anti-PD-L1 immune checkpoint inhibitor (ICI) therapy where possible, or 1L ICI therapy in cisplatin-ineligible patients with PD-L1+ tumors. However, long-term outcomes remain poor and only a minority of patients receive 2L therapy. The JAVELIN Bladder 100 trial-which assessed avelumab (anti-PD-L1 antibody) as 1L maintenance therapy plus best supportive care (BSC) versus BSC alone in patients with advanced UC that had not progressed with 1L platinum-based chemotherapy-is the only phase 3 trial of ICI-based treatment in the 1L setting to show significantly improved overall survival, and this treatment approach is now recommended in updated treatment guidelines. Available data from the trial suggest that efficacy and safety in patients enrolled in the Asia-Pacific region were similar to findings in the overall population. In this review, we discuss the treatment of advanced UC, with a specific focus on studies in the Asia-Pacific region, and summarize key findings supporting the use of avelumab 1L maintenance as a standard of care in this setting both in cisplatin-eligible and cisplatin-ineligible patients and irrespective of PD-L1 status.

Abstract
OBJECTIVE To describe the current treatment landscape in advanced urothelial cancer (aUC)/metastatic urothelial cancer and in particular to review the relevant literature highlighting recent advances in the treatment of patients with aUC after progression on chemotherapy and immune checkpoint inhibitor (ICI). BACKGROUND aUC is a very aggressive disease with poor outcomes. Over the past several years, its treatment landscape has seen significant advances with the approval of ICI and targeted agents, which have led to improved outcomes. The current standard of care for most patients with aUC involves platinum-based chemotherapy followed by ICI after progression or as switch maintenance therapy (if no progression after chemotherapy). Treatment of patients following progression on ICI is more challenging, but novel therapies have been approved, such as erdafitinib for tumors with fibroblast growth factor receptor 2 (FGFR2) or FGFR3 activating mutation or fusion (can also be used following progression on platinum-based chemotherapy), enfortumab vedotin (EV) and sacituzumab govitecan (SG) in an unselected patient population. Many other trials in this space are currently ongoing and other promising agents may also potentially become available in the future. METHODS Narrative overview of the recent literature relevant to the treatment of advanced/metastatic urothelial cancer following progression on chemotherapy and ICI was undertaken. Relevant literature was obtained from review of computerized databases including pubmed.gov and proceedings of major conferences including American Society of clinical Oncology (ASCO) Meetings, GU ASCO Symposia and European Society of Medical Oncology (ESMO) Meetings. CONCLUSIONS In this narrative review, we highlight the current dynamic treatment landscape in aUC, emphasizing the recent important developments and a few examples of ongoing clinical trials. In particular, we focus on therapy options available following progression on platinum-based chemotherapy and ICI, a treatment space where until recently there had been no FDA-approved treatment options. The recent pivotal trials of antibody drug conjugates (ADCs) that led to FDA approvals in this space are highlighted, as are other agents currently in development. We conclude by discussing future directions and ongoing challenges in this evolving disease space.

Erdafitinib treatment in Brazilian patients with metastatic urothelial carcinoma (mUC): real-world evidence from an Expanded Access Program. Ther Adv Med Oncol 2021; 13:17588359211015499. [PMID: 34046088 PMCID: PMC8135201 DOI: 10.1177/17588359211015499] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Accepted: 04/09/2021] [Indexed: 11/16/2022] Open
Abstract
Background Erdafitinib is the first targeted therapy approved for the treatment of patients with metastatic urothelial carcinoma (mUC). Approval was based on a phase II single-arm trial that demonstrated significant activity of erdafitinib in patients with tumors harboring FGFR2/3 alterations. In Brazil, an Expanded Access Program (EAP) provided patients with early access to erdafitinib prior to market authorization. The current report describes characteristics and outcomes of patients with mUC on erdafitinib therapy. Methods Patients with mUC that failed first- and second-line systemic therapies were screened for FGFR2/3 alterations in primary or metastatic tumor tissues. Patients with FGFR2/3 alterations were selected to receive erdafitinib at the standard dosing schedule and were followed prospectively to evaluate the efficacy and safety outcomes. Results From 19 April 2019, through 13 March 2020, 47 patients with mUC from 10 Brazilian centers were tested for FGFR2/3 alterations. Alterations in FGFR2/3 were found in 12 patients (25.5%) and all of them were eligible for the EAP. Four patients (33%) had partial response, while two patients (17%) had stable disease. Progressive disease, the best response, was observed in five patients (42%). At a median follow-up of 16.2 months, the median time to treatment failure (TTF) was 2.8 months. When considering only patients with objective response, the median TTF was 5.3 months. Adverse events (AEs) were reported for any grade and grade 3 or higher in 10 patients (83%) and 5 patients (42%), respectively. The most common AE was hyperphosphatemia. Conclusion This first real-world evidence report of heavily treated patients with mUC confirms the efficacy and safety of erdafitinib in a disease setting with a lack of treatment options.
