Abstract
Aim: Investigate oncologist and patient preferences for the first-line treatment of advanced urothelial carcinoma. Materials & methods: A discrete-choice experiment was used to elicit treatment attribute preferences, including patient treatment experience (number and duration of treatments and grade 3/4 treatment-related adverse events), overall survival and treatment administration frequency. Results: The study included 151 eligible medical oncologists and 150 patients with urothelial carcinoma. Both physicians and patients appeared to prefer treatment attributes related to overall survival, treatment-related adverse events and the number and duration of the medications in a regimen over frequency of administration. Overall survival had the most influence in driving oncologists' treatment preferences, followed by the patient's treatment experience. Patients found the treatment experience the most important attribute when considering options, followed by overall survival. Conclusion: Patient preferences were based on treatment experience, while oncologists preferred treatments that prolong overall survival. These results help to direct clinical conversations, treatment recommendations and clinical guideline development.

[PMID: 37530414 PMCID: PMC10399482 DOI: 10.1080/19420862.2023.2236740] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 07/10/2023] [Accepted: 07/11/2023] [Indexed: 08/03/2023] Open
Abstract
Antibody-based immune checkpoint blockade (ICB)-based therapeutics have become effective clinical applications for cancers. Applications of monoclonal antibodies (mAbs) to de-activate the PD-1-PD-L1 pathway could effectively reverse the phenotype of depleted activated thymocytes (T cells) to recover their anti-tumoral activities. High-resolution structures of the complexes of the therapeutic monoclonal antibodies with PD-1 or PD-L1 have revealed the key inter-molecular interactions and provided valuable insights into the fundamental mechanisms by which these antibodies inhibit PD-L1-PD-1 binding. Each anti-PD-1 mAb exhibits a unique blockade mechanism, such as interference with large PD-1-PD-L1 contacting interfaces, steric hindrance by overlapping a small area of this site, or binding to an N-glycosylated site. In contrast, all therapeutic anti-PD-L1 mAbs bind to a similar area of PD-L1. Here, we summarized advances in the structural characterization of the complexes of commercial mAbs that target PD-1 or PD-L1. In particular, we focus on the unique characteristics of those mAb structures, epitopes, and blockade mechanisms. It is well known that the use of antibodies as anti-tumor drugs has increased recently and both PD-1 and PD-L1 have attracted substantial attention as target for antibodies derived from new technologies. By focusing on structural characterization, this review aims to aid the development of novel antibodies targeting PD-1 or PD-L1 in the future.

Pivotal role of PD-1/PD-L1 immune checkpoints in immune escape and cancer progression: Their interplay with platelets and FOXP3+Tregs related molecules, clinical implications and combinational potential with phytochemicals. Semin Cancer Biol 2022; 86:1033-1057.

Abstract
Immune checkpoint proteins including programmed cell death protein 1 (PD-1), its ligand PD-L1 and cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) are involved in proliferation, angiogenesis, metastasis, chemoresistance via immune escape and immune tolerance by disturbing cytotoxic T cell activation. Though many clinical trials have been completed in several cancers by using immune checkpoint inhibitors alone or in combination with other agents to date, recently multi-target therapy is considered more attractive than monotherapy, since immune checkpoint proteins work with other components such as surrounding blood vessels, dendritic cells, fibroblasts, macrophages, platelets and extracellular matrix within tumor microenvironment. Thus, in the current review, we look back on research history of immune checkpoint proteins and discuss their associations with platelets or tumor cell induced platelet aggregation (TCIPA) and FOXP3+ regulatory T cells (Tregs) related molecules involved in immune evasion and tumor progression, clinical implications of completed trial results and signaling networks by phytochemicals for combination therapy with immune checkpoint inhibitors and suggest future research perspectives.

Abstract
Nowadays, the landscape of cancer treatments has broadened thanks to the clinical application of immunotherapeutics. After decades of failures, cancer immunotherapy represents an exciting alternative for those patients suffering from a wide variety of cancers, especially for those skin cancers, such as the early stages of melanoma. However, those cancers affecting internal organs still face a long way to success, because of the poor biodistribution of immunotherapies. Here, nanomedicine appears as a hopeful strategy to modulate the biodistribution aiming at target organ accumulation. In this way, efficacy will be improved, while reducing the side effects at the same time. In this review, we aim to highlight the most promising cancer immunotherapeutic strategies. From monoclonal antibodies and their traditional use as targeted therapies to their current use as immune checkpoint inhibitors; as well as adoptive cell transfer therapies; oncolytic viruses, and therapeutic cancer vaccination. Then, we aim to discuss the important role of nanomedicine to improve the performance of these immunotherapeutic tools to finally review the already marketed nanomedicine-based cancer immunotherapies.

Immune-inflammatory biomarkers as prognostic factors for immunotherapy in pretreated advanced urinary tract cancer patients: an analysis of the Italian SAUL cohort. ESMO Open 2021; 6:100118. [PMID: 33984678 PMCID: PMC8134706 DOI: 10.1016/j.esmoop.2021.100118] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Revised: 03/04/2021] [Accepted: 03/17/2021] [Indexed: 12/18/2022] Open
Abstract
Background Reliable and affordable prognostic and predictive biomarkers for urothelial carcinoma treated with immunotherapy may allow patients' outcome stratification and drive therapeutic options. The SAUL trial investigated the safety and efficacy of atezolizumab in a real-world setting on 1004 patients with locally advanced or metastatic urothelial carcinoma who progressed to one to three prior systemic therapies. Patients and methods Using the SAUL Italian cohort of 267 patients, we investigated the prognostic role of neutrophil-to-lymphocyte ratio (NLR) and systemic immune-inflammation index (SII) and the best performing one of these in combination with programmed death-ligand 1 (PD-L1) with or without lactate dehydrogenase (LDH). Previously reported cut-offs (NLR >3 and NLR >5; SII >1375) in addition to study-defined ones derived from receiver operating characteristic (ROC) analysis were used. Results The cut-off values for NLR and SII by the ROC analysis were 3.65 (sensitivity 60.4; specificity 63.0) and 884 (sensitivity 64.4; specificity 67.5), respectively. The median overall survival (OS) was 14.7 months for NLR <3.65 [95% confidence interval (CI) 9.9-not reached (NR)] versus 6.0 months for NLR ≥3.65 (95% CI 3.9-9.4); 14.7 months for SII <884 (95% CI 10.6-NR) versus 6.0 months for SII ≥884 (95% CI 3.7-8.6). The combination of SII, PD-L1, and LDH stratified OS better than SII plus PD-L1 through better identification of patients with intermediate prognosis (77% versus 48%, respectively). Multivariate analyses confirmed significant correlations with OS and progression-free survival for both the SII + PD-L1 + LDH and SII + PD-L1 combinations. Conclusion The combination of immune-inflammatory biomarkers based on SII, PD-L1, with or without LDH is a potentially useful and easy-to-assess prognostic tool deserving validation to identify patients who may benefit from immunotherapy alone or alternative therapies. Reliable biomarkers for immunotherapy may assist in treatment decision making and clinical trial design and interpretation. Immune-inflammatory biomarkers were investigated for their prognostic role within the Italian SAUL study cohort. ROC-based cut-offs were 3.65 for NLR and 884 for SII. Both NLR and SII were prognostic with SII performing slightly better than NLR. The combination of SII, PD-L1, and LDH stratified OS better than SII + PD-L1; both were independent prognostic factors.

Abstract
OPINION STATEMENT Immune checkpoint inhibitors have importantly improved the outcome of patients with urothelial carcinoma. Different immune checkpoint inhibitors are currently approved and used in first- and second-line setting. The multiple agents currently approved in these setting make the choice sometimes difficult for clinicians. Furthermore, only a minority of patients present drastic response and long-term benefit with current immunotherapy. In this review, we describe the current use of immunotherapy in urothelial carcinoma but we also highlight the new strategies of treatment involving immune checkpoint inhibitors; we describe the place of immunotherapy with chemotherapy, targeted agents, and anti-angiogenic agents, incorporating the recent results presented at ASCO 2020. This review explores also the different action mechanisms of immune checkpoint inhibitors and the molecular rational to evaluate these agents in other strategies, such as maintenance and salvage strategies. The new advances in biomarker development are also presented.

Abstract
Monoclonal antibodies (mAbs) have become one of the most important classes of biopharmaceutical products, and they continue to dominate the universe of biopharmaceutical markets in terms of approval and sales. They are the most profitable single product class, where they represent six of the top ten selling drugs. At the beginning of the 1990s, an in vitro antibody selection technology known as antibody phage display was developed by John McCafferty and Sir. Gregory Winter that enabled the discovery of human antibodies for diverse applications, particularly antibody-based drugs. They created combinatorial antibody libraries on filamentous phage to be utilized for generating antigen specific antibodies in a matter of weeks. Since then, more than 70 phage–derived antibodies entered clinical studies and 14 of them have been approved. These antibodies are indicated for cancer, and non-cancer medical conditions, such as inflammatory, optical, infectious, or immunological diseases. This review will illustrate the utility of phage display as a powerful platform for therapeutic antibodies discovery and describe in detail all the approved mAbs derived from phage display.

Abstract
PURPOSE The aim of the study was to evaluate the relative contributions of incidence, stage-specific relative survival, and stage ascertainment to changes in bladder cancer (BC) prevalence and incidence-based mortality. METHODS Partitioning of prevalence and incidence-based mortality trends into their epidemiologic components. RESULTS BC prevalence estimated from our model increased but at monotonically decreasing rates until 2007, after which it decreased again. The main forces underlying observed trends in BC prevalence were relative BC survival, which improved throughout the period, and BC incidence, which increased at a decreasing rate until 2005 and declined thereafter. Mortality of persons ever diagnosed with BC increased at an increasing rate until 1997, increased at a decreasing rate from 1997 to 2005, and decreased thereafter. The primary forces accounting for mortality trends were changes in mortality in the general population, which improved at an increasing rate during most of 1992-2010, the most important factor, and changes in incidence. Stage ascertainment did not improve during 1992-2010. CONCLUSIONS Although mortality rates improved, these gains largely reflected improvements in U.S. population survival rather than from improvements in BC-specific outcomes.

Abstract
INTRODUCTION The immune checkpoint inhibitors (ICI) programmed cell death protein and ligands 1 (PD1- and PD-L1) as well as cytotoxic T-lymphocyte-associated protein 4 have demonstrated clinical efficacy in genitourinary cancer. While different ICI exist, focus of the current study work was to evaluate the PD-L1 antibody avelumab within this framework of ICI. AREAS COVERED The manuscript reviews the pharmacological characteristics and preclinical and clinical data of avelumab in the treatment for advanced or metastatic genitourinary cancers. It highlights its respective clinical relevance and special features in the context of the other available ICI. EXPERT OPINION Avelumab has shown promising antitumor activity and a manageable safety profile in patients with mRCC and mUC as mono- and combination therapy. The approach of an avelumab maintenance therapy in mUC is promising and could become part of future clinical practice. Results of ICI used in the neoadjuvant or adjuvant setting are eagerly awaited. Avelumab's uniqueness is its capacity to enhance antibody-dependent cell-mediated cytotoxicity. Because of this, currently ongoing clinical trials investigate the combination of avelumab with other immune modulating agents like IL-12 and IL-15. Thereby, it can be assumed that avelumab will have an ongoing role in the treatment of patients with genitourinary tumors.

Abstract
Introduction: The incidence of advanced renal cell carcinoma (RCC) is increasing. Over the last 10 years targeted therapies have led to improved efficacy outcomes for renal carcinoma, including longer survival. However, the majority of patients develop disease progression within a year of initiation of first-line therapy. Recently a number of new regimens have been investigated including the combination of immune checkpoint inhibitors with VEGF inhibitors.Areas covered: In this review, we assess the efficacy and safety of avelumab/axitinib in treatment-naïve patients with metastatic RCC and compare this combination to other current and emerging treatment regimens. In the Javelin 101 phase III registration trial, avelumab/axitinib demonstrated superior response rates and progression-free survival compared to sunitinib. However, after follow-up of 11.6 months, there was no significant difference in overall survival (OS). Avelumab/axitinib showed a tolerable safety profile. Adverse events were manageable and were in line with expected toxicities from the single agents.Expert Opinion: Avelumab/axitinib has shown impressive efficacy and a tolerable safety profile in metastatic RCC. The future role of this treatment combination in the rapidly evolving landscape of novel combinations in this disease will have to be defined.

Abstract
Immunotherapy, specifically research involving immune checkpoint blockers (ICBs), has become a popular trend in anticancer research over the last three years. Due to the difficulties and often poor translation of results from in-vitro models, in-vivo models have become more relevant than ever. With the discovery of NOD, Prkdcscid , and Il2rγ-/- mutations, patient-derived xenograft (PDX) mouse models were developed, providing an ideal environment for ICBs testing. By implanting a PDX with either CD34+ or peripheral blood mononuclear cells, we can create a human immune system capable of mounting a response against tumor burden. These animal models are currently being used to study molecular mechanisms, test drug efficacy, and trial drug combinations. Others have found use for these humanized mouse models as surrogates to represent otherwise uncommon diseases. Limitations remain with regards to what the models are capable of, but in the short amount of time between the development of these models and heightened interest in ICBs, these mice have already shown utility for future developments in the field of immunotherapy.

Abstract
The treatment of genitourinary malignancies has dramatically evolved over recent years. Renal cell carcinoma, urothelial carcinoma of the bladder, and prostate adenocarcinoma are the most commonly encountered genitourinary malignancies and represent a heterogeneous population of cancers, in both histology and approach to treatment. However, all three cancers have undergone paradigm shifts in their respective therapeutic landscapes due to a greater understanding of their underlying molecular mechanisms and oncogenic drivers. The advance that has gained the most recent traction has been the advent of immunotherapies, particularly immune checkpoint inhibitors. Immunotherapy has increased overall survival and even provided durable responses in the metastatic setting in some patients. The early success of immune checkpoint inhibitors has led to further drug development with the emergence of novel agents which modulate the immune system within the tumor microenvironment. Notwithstanding immunotherapy, investigators are also developing novel agents tailored to a variety of targets including small-molecule tyrosine kinase inhibitors, mTOR inhibitors, and novel fusion proteins to name a few. Erdafitinib has become the first targeted therapy approved for metastatic bladder cancer. Moreover, the combination therapy of immune checkpoint inhibitors with targeted agents such as pembrolizumab or avelumab with axitinib has demonstrated both safety and efficacy and just received FDA approval for their use. We are in an era of rapid progression in drug development with multiple exciting trials and ongoing pre-clinical studies. We highlight many of the promising new emerging therapies that will likely continue to improve outcomes in patients with genitourinary malignancies.

[PMID: 30884772 PMCID: PMC6470519 DOI: 10.3390/ijms20061326] [Citation(s) in RCA: 39] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2019] [Revised: 03/10/2019] [Accepted: 03/12/2019] [Indexed: 02/08/2023] Open
Abstract
In tumor microenvironment, the programmed death 1 (PD-1) immune checkpoint has a crucial role of mechanism of T cell exhaustion leading to tumor evasion. Ligands of PD-1, programmed death ligand 1/2 (PD-L1/L2) are over-expressed in tumor cells and participate in prolonged tumor progression and survivals. Recently, clinical trials for patients who failed to obtain an optimal response prior to standardized chemotherapy in several solid cancers have been focused on targeting therapy against PD-1 to reduce disease progression rates and prolonged survivals. Since various inhibitors targeting the immune checkpoint in PD-1/PD-L1 pathway in solid cancers have been introduced, promising approach using anti-PD-1 antibodies were attempted in several types of hematologic malignances. In diffuse large B cell lymphoma (DLBCL) as the most common and aggressive B cell type of non-Hodgkin’s lymphoma, anti-PD-1 and anti-PD-L1 antibodies were studies in various clinical trials. In this review, we summarized the results of several studies associated with PD-1/PD-L1 pathway as an immune evasion mechanism and described clinical trials about targeting therapy against PD-1/PD-L1 pathway in DLBCL.
