Abstract
Anemia is common in cancer patients and impacts on quality of life and prognosis. It is typically multifactorial, often involving different pathophysiological mechanisms, making treatment a difficult task. In patients undergoing active anticancer treatments like chemotherapy, decreased red blood cell (RBC) production due to myelosuppression generally predominates, but absolute or functional iron deficiency frequently coexists. Current treatments for chemotherapy-related anemia include blood transfusions, erythropoiesis-stimulating agents, and iron supplementation. Each option has limitations, and there is an urgent need for novel approaches. After decades of relative immobilism, several promising anti-anemic drugs are now entering the clinical scenario. Emerging novel classes of anti-anemic drugs recently introduced or in development for other types of anemia include activin receptor ligand traps, hypoxia-inducible factor-prolyl hydroxylase inhibitors, and hepcidin antagonists. Here, we discuss their possible role in the treatment of anemia observed in patients receiving anticancer therapies.

Evidence and efficacy of immune checkpoint- and tyrosine kinase inhibitor combinations in advanced solid cancers. Cancer Treat Rev 2024; 125:102718. [PMID: 38521009 DOI: 10.1016/j.ctrv.2024.102718] [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: 01/17/2024] [Revised: 03/03/2024] [Accepted: 03/09/2024] [Indexed: 03/25/2024]
Abstract
Immune checkpoint inhibitors (ICI) and tyrosine kinase inhibitors (TKI) have gained therapeutical significance in cancer therapy over the last years. Due to the high efficacy of each substance group, additive or complementary effects are considered, and combinations are the subject of multiple prospective trials in different tumor entities. The majority of available data results from clinical phase I and II trials. Although regarded as well-tolerated therapies ICI-TKI combinations have higher toxicities compared to monotherapies of one of the substance classes and some combinations were shown to be excessively toxic leading to discontinuation of trials. So far, ICI-TKI combinations with nivolumab + cabozantinib, pembrolizumab + axitinib, avelumab + axitinib, pembrolizumab + lenvatinib have been approved in advanced renal cell (RCC), with pembrolizumab + lenvatinib in endometrial carcinoma and with camrelizumab + rivoceranib in hepatocellular carcinoma (HCC). Several ICI-TKI combinations are currently investigated in phase I to III trials in various other cancer entities. Further, the optimal sequence of ICI-TKI combinations is an important subject of investigation, as cross-resistances between the substance classes were observed. This review reports on clinical trials with ICI-TKI combinations in different cancer entities, their efficacy and toxicity.

Cardiovascular Adverse Events Associated With Second-generation Bruton Tyrosine Kinase Inhibitor Therapy: A Systematic Review and Meta-analysis. Clin Ther 2024; 46:134-145. [PMID: 38102000 DOI: 10.1016/j.clinthera.2023.11.014] [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: 07/30/2023] [Revised: 09/17/2023] [Accepted: 11/16/2023] [Indexed: 12/17/2023]
Abstract
PURPOSE Cardiovascular adverse events (CVAEs) are common adverse effects of first-generation Bruton tyrosine kinase inhibitors (BTKis) and limit their use considerably. This led to the development of second-generation BTKis-acalabrutinib and zanubrutinib-which are more selective, potent, and presumed to have better safety profiles than the previous group of medications. However, there have been sporadic reports of CVAEs associated with second-generation BTKis in clinical practice. To address this issue, a comprehensive meta-analysis to pool the documented CVAEs was performed, including major hemorrhage, any bleeding, atrioventricular block, atrial fibrillation/flutter, pericardial effusion, pericarditis, heart failure, cardiac arrest, myocardial infarction, hypertension, hypotension, and stroke. This meta-analysis incorporated 8 studies. Among these, 6 were Phase III trials and 2 were Phase II trials. These studies collectively enrolled a total of 2938 patients. METHODS Multiple databases, including PubMed, MEDLINE, Cochrane Library, Scopus, and EMBASE, were systematically searched for relevant clinical trials from inception through January 14, 2023. The effect measure used was odds ratio (OR) and 95% CI. FINDINGS Of a total of 1774 studies identified during the initial database search, 8 were included in the meta-analysis. The incidence of overall and cardiovascular mortality was comparable between the 2 groups. There were no significant differences observed for cardiovascular mortality (OR = 0.36; 95% CI, 0.08-1.65; n = 2588; I2 = 45%; P = 0.19). Similar results were found for all-cause mortality (OR = 0.85; 95% CI, 0.67-1.07), any bleeding (OR = 1.90; 95% CI, 0.88-4.09), major bleeding (OR = 1.07; 95% CI, 0.65-1.76), atrioventricular block (OR = 0.74; 95% CI, 0.15-3.68), atrial fibrillation/flutter (OR = 0.74; 95% CI, 0.37-1.50), and other CVAEs associated with second-generation BTKis. IMPLICATIONS Based on the available evidence, there is no indication of worse cardiovascular outcomes or superiority of second-generation BTKis compared with standard treatments in terms of safety profile. However, additional large-scale controlled trials are needed to provide robust support for the superior tolerability of new-generation BTKis.

Abstract
Background: Bladder cancer and therapy responses hinge on immune profiles in the tumor microenvironment (TME) and blood, yet studies linking tumor-infiltrating immune cells to peripheral immune profiles are limited. Methods: DNA methylation cytometry quantified TME and matched peripheral blood immune cell proportions. With tumor immune profile data as the input, subjects were grouped by immune infiltration status and consensus clustering. Results: Immune hot and cold groups had different immune compositions in the TME but not in circulating blood. Two clusters of patients identified with consensus clustering had different immune compositions not only in the TME but also in blood. Conclusion: Detailed immune profiling via methylation cytometry reveals the significance of understanding tumor and systemic immune relationships in cancer patients.

Abstract
BACKGROUND Immune checkpoint inhibitors are increasingly important in the treatment algorithm for locally advanced and metastatic bladder cancer. Numerous ongoing studies are investigating these agents as first- and second-line therapies, both alone and in combination with chemotherapy or in a maintenance therapy setting. OBJECTIVES To assess the effects of immune checkpoint inhibitors compared to chemotherapy as first- and second-line treatment of advanced or metastatic urothelial carcinoma. SEARCH METHODS We performed a comprehensive search including the Cochrane Library, MEDLINE, Embase, three other databases, several trial registers, other sources of gray literature, and conference proceedings, with no restrictions on language of publication. We limited the search period to run from 2000 until August 2022. SELECTION CRITERIA We included randomized controlled trials (RCTs) using immunotherapy versus chemotherapy and would have considered non-randomized trials in the absence of randomized trial data. Participants had locally advanced inoperable (cT4b or N+, or both) or metastatic (M1) (or both) urothelial carcinoma of the bladder or upper urinary tract. We excluded studies of people in whom immunotherapy was used in combination with chemotherapy or in a surveillance setting. DATA COLLECTION AND ANALYSIS Two review authors independently classified studies for inclusion and abstracted data from included studies. We performed statistical analyses using a random-effects model and interpreted them according to the Cochrane Handbook for Systematic Reviews of Interventions. We used GRADE guidance to rate the certainty of evidence on a per-outcome basis. MAIN RESULTS We included five RCTs and identified seven single-armed studies. The RCTs included 3572 participants comparing immunotherapy versus chemotherapy for the treatment of locally advanced and metastatic bladder cancer. First-line therapy Immunotherapy probably has little to no effect on the risk of death from any cause when used as first-line therapy compared to chemotherapy (hazard ratio [HR] 0.97, 95% confidence interval [CI] 0.87 to 1.07; I2 = 0%; 3 studies, 2068 participants; moderate-certainty evidence). This corresponds to 750 deaths per 1000 participants with chemotherapy and 11 fewer (45 fewer to 26 more) deaths per 1000 participants with immunotherapy at 36 months. Immunotherapy probably has little to no effect on health-related quality of life (mean difference (MD) 4.10, 95% CI 3.83 to 4.37; 1 study, 393 participants; moderate-certainty evidence), when assuming a minimal clinically important difference (MCID) of at least 6 points (using the Functional Assessment of Cancer Therapy - Bladder [FACT-BL] tool; scale 0 to 156 with higher scores representing better quality of life). Immunotherapy probably reduces adverse events grade 3 to 5 (RR 0.47, 95% CI 0.29 to 0.75; I2 = 97%; 3 studies, 2046 participants; moderate-certainty evidence). This corresponds to 908 grade 3 to 5 adverse events per 1000 participants with chemotherapy, with 481 fewer (644 fewer to 227 fewer) grade 3 to 5 adverse events per 1000 participants with immunotherapy. We found no evidence for the outcome time to death from bladder cancer. Immunotherapy probably increases the risk of time to disease progression (HR 1.33, 95% CI 1.17 to 1.50; I2 = 0%; 2 studies, 1349 participants; moderate-certainty evidence). This corresponds to 660 events per 1000 participants with chemotherapy and 102 more (57 more to 152 more) events per 1000 participants with immunotherapy at 36 months. Immunotherapy may reduce discontinuations due to adverse effects (RR 0.47, 95% CI 0.20 to 1.10; I2 = 94%; 3 studies, 2046 participants; low-certainty evidence). This corresponds to 338 discontinuations per 1000 participants with chemotherapy and 179 fewer (271 fewer to 34 more) discontinuations per 1000 participants with immunotherapy. Second-line therapy Immunotherapy may reduce the risk of death from any cause when used as second-line therapy (HR 0.72, 95% CI 0.63 to 0.81; I2 = 0%; 2 studies, 1473 participants; low-certainty evidence). This corresponds to 920 deaths per 1000 participants with chemotherapy (vinflunine, paclitaxel, docetaxel) and 59 fewer (95 fewer to 28 fewer) deaths per 1000 participants with immunotherapy at 36 months. Immunotherapy may have little to no effect on health-related quality of life when compared to chemotherapy (MD 4.82, 95% CI -3.11 to 12.75; I2 = 85%; 2 studies, 727 participants; low-certainty evidence), assuming an MCID of at least 10 points (using the EORTC QLQ tool; scale 0 to 100 with higher scores representing better quality of life). Immunotherapy may reduce adverse events grade 3 to 5 in participants undergoing second-line therapy (RR 0.89, 95% CI 0.81 to 0.97; I2 = 9%; 2 studies, 1423 participants; low-certainty evidence). This corresponds to 630 grade 3 to 5 adverse events per 1000 participants with chemotherapy and 76 fewer (126 fewer to 25 fewer) grade 3 to 5 adverse events per 1000 participants with immunotherapy. We found no evidence for the outcome of time to death from bladder cancer. We are very uncertain if immunotherapy reduces the risk of disease progression (HR 0.99, 95% CI 0.84 to 1.16; I2 = 0%; 2 studies, 1473 participants; very low-certainty evidence). Immunotherapy may reduce discontinuations due to adverse events in participants undergoing second-line therapy (RR 0.35, 95% CI 0.17 to 0.72; I2 = 69%; 2 studies, 1473 participants; low-certainty evidence). This corresponds to 110 discontinuations per 1000 participants with chemotherapy and 72 fewer (91 fewer to 31 fewer) discontinuations per 1000 participants with immunotherapy. AUTHORS' CONCLUSIONS Compared to chemotherapy, immunotherapy for treating advanced or metastatic urothelial carcinoma probably has little to no effect on the risk of death from any cause when used as first-line therapy. Still, it may reduce the risk of death from any cause when used as second-line therapy. Health-related quality of life for participants receiving first- and second-line therapy does not appear to be affected by immunotherapy. Immunotherapy probably reduces or may reduce adverse events grade 3 to 5 when used as first- and second-line therapy, respectively.

Abstract
Ibrutinib is a first-in-class Bruton's tyrosine kinase inhibitor approved for the treatment of various B-cell malignancies and chronic graft-versus-host disease. We evaluated the safety and efficacy of ibrutinib, alone or combined with standard-of-care regimens, in adults with advanced urothelial carcinoma (UC). Once-daily ibrutinib was administered orally at 840 mg (single-agent or with paclitaxel) or at 560 mg (with pembrolizumab). Phase 1b determined the recommended phase 2 dose (RP2D) of ibrutinib, and phase 2 assessed progression-free survival (PFS), overall response rate (ORR), and safety. Thirty-five, eighteen, and fifty-nine patients received ibrutinib, ibrutinib plus pembrolizumab, and ibrutinib plus paclitaxel at the RP2D, respectively. Safety profiles were consistent with those of the individual agents. The best-confirmed ORRs were 7% (two partial responses) with single-agent ibrutinib and 36% (five partial responses) with ibrutinib plus pembrolizumab. Median PFS was 4.1 months (range, 1.0-37.4+) with ibrutinib plus paclitaxel. The best-confirmed ORR was 26% (two complete responses). In previously treated patients with UC, ORR was higher with ibrutinib plus pembrolizumab than with either agent alone (historical data in the intent-to-treat population). ORR with ibrutinib plus paclitaxel was greater than historical values for single-agent paclitaxel or ibrutinib. These data warrant further evaluation of ibrutinib combinations in UC.

Clin Transl Med 2023; 13:e1255. [PMID: 37157934 PMCID: PMC10167412 DOI: 10.1002/ctm2.1255] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 03/12/2023] [Accepted: 04/17/2023] [Indexed: 05/10/2023] Open
Abstract
BACKGROUND Recurrence and metastasis of bladder cancer are major factors affecting patient prognosis. Endoscopic cryoablation achieved a better clinical outcome among clinical patients and could be synergistic with ICIs. Thus, this study aimed to evaluate the immunological mechanism of cryoablation for bladder cancer to reveal the therapeutic mechanism. METHODS We systematically reviewed the clinical prognosis of patients underwent cryoablation at Huashan Hospital in these first-in-human studies (ChiCTR-INR-17013060). Murine models were constructed to explore cryoablation-induced tumour-specific immunity, which was further confirmed by primary bladder tumour organoids and autologous lymphocytes cocultured system. RESULTS Cryoablation improved progression-free survival and recurrence-free survival respectively. Assessment of murine models after cryoablation confirmed microenvironment remodelling and tumour-specific T cells expansion. Enhanced antitumour effects were found after coculture of organoids with autologous lymphocytes collected from post-cryoablation. We also demonstrated cryoablation-induced tumour elimination required IFNGR expression on tumour cells. In addition, a long-lasting antitumour memory response is achieved by cryoablation and could be enhanced after combination with ICIs. CONCLUSIONS This study revealed endoscopic cryoablation is an efficient and safe therapy for bladder tumour treatment. The tumour-specific immune responses induced by cryoablation could reduce tumour recurrence and metastasis.

Abstract
Background: Anti-PD-(L)1 antibody monotherapy or in combination with VEGF(R) blockade has been applied widely for cancer treatment. Whether combination therapy increases irAEs still remains controversial. Methods: A systematic review and meta-analysis comparing PD-(L)1 and VEGF(R) blockade combination therapy with PD-(L)1 inhibitors alone was performed. Phase II or III randomized clinical trials reporting irAEs or trAEs were included. The protocol was registered with PROSPERO, CRD42021287603. Results: Overall, 77 articles were included in the meta-analysis. A total of 31 studies involving 8,638 participants were pooled and an incidence for PD-(L)1 inhibitor monotherapy with any grade and grade ≥3 irAEs of 0.25 (0.20, 0.32) and 0.06 (0.05, 0.07), respectively, were reported. Two studies with 863 participants pooled for PD-(L)1 and VEGF(R) blockade showed that an incidence of any grade and grade ≥3 irAEs were 0.47 (0.30, 0.65) and 0.11 (0.08, 0.16), respectively. Regarding pairwise comparisons for irAEs, only one study was included, indicating no significant difference between the two regimens in terms of colitis, hyperthyroidism, and hypothyroidism for any grade and grade ≥3, while there was a trend of higher incidence for any grade hyperthyroidism under the combination therapy. The incidence of reactive cutaneous capillary endothelial proliferation (RCCEP) was as high as 0.80 under camrelizumab monotherapy. Conclusion: Total incidences of any grade and grade ≥3 irAEs were higher in the combination treatment group. Direct comparisons indicated no significant difference between the two regimens for any grade and grade ≥3 specific irAEs. RCCEP and thyroid disorders need to be paid attention to clinically. Moreover, trials with direct comparisons are needed and the safety profiles of the two regimens should be further explored. Exploration of the mechanism of action and regulatory management of adverse events should be enhanced.

Efficacy and Safety of PD-1/PD-L1 Checkpoint Inhibitors versus Anti-PD-1/PD-L1 Combined with Other Therapies for Tumors: A Systematic Review. Cancers (Basel) 2023; 15:cancers15030682. [PMID: 36765640 PMCID: PMC9913120 DOI: 10.3390/cancers15030682] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Revised: 12/29/2022] [Accepted: 01/18/2023] [Indexed: 01/24/2023] Open
Abstract
OBJECTIVE In recent years, the anti-programmed cell death protein-1 and its ligand (PD-1/PD-L1) or combination therapies have been recommended as an alternative emerging choice of treatment for oncology patients. However, the efficacy and adverse events of different combination strategies for the treatment of tumors remain controversial. METHODS PubMed, Embase, Cochrane Library, the American Society of Clinical Oncology (ASCO), and the European Society of Medicine Oncology (ESMO) were searched from database inception until 16 February 2022. The endpoints of objective response rate (ORR), disease control rate (DCR), overall survival (OS), progression-free survival (PFS), and adverse events (AEs) were analyzed from different treatment schemes and tumor types. The protocol was registered in PROSPERO (CRD42022328927). RESULTS This meta-analysis included forty-eight eligible studies. Combination therapy has improved ORR (RR = 1.40, p < 0.001), DCR (RR = 1.22, p < 0.001), and PFS (the median survival ratio (MSR) was estimated to be 1.475 p < 0.001) compared to anti-PD-1/PD-L1 but had no significant benefit on OS (MSR was estimated to be 1.086 p = 0.117). Besides, combination treatment strategies are more toxic in any grade AEs (RR = 1.13, p < 0.001) and grade 3-5 AEs (RR = 1.81, p < 0.001). CONCLUSIONS Treatment with PD-1/PD-L1 inhibitors in combination with other antitumor therapies improve patients' ORR, DCR, and PFS compared to anti-PD-1/PD-L1. However, it is regrettable that there is no benefit to OS and an increased risk of AEs in combinatorial therapies.

Oncol Lett 2022; 25:48. [PMID: 36644138 PMCID: PMC9811622 DOI: 10.3892/ol.2022.13634] [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: 08/24/2022] [Accepted: 11/11/2022] [Indexed: 12/23/2022] Open
Abstract
CD20-negative diffuse large B-cell lymphoma (DLBCL) is a rare type of lymphoproliferative disorder characterized by a high degree of aggressiveness, a tendency for extranodal invasion and chemotherapeutic resistance. CD20-negative DLBCL originating from the nervous system is rarer. In primary central nervous system lymphoma (PCNSL), >90% of cases are histologically classified as DLBCL. The present study reports the case of a 65-year-old female with CD20-negative PCNSL, whose primary clinical symptom was a persistent headache. Serum tests for human immunodeficiency virus, Epstein-Barr virus-DNA, human herpesvirus 8, hepatitis B and hepatitis C were negative. Cranial magnetic resonance imaging suggested multiple intracranial occupancies. The neoplastic cells were found to be positive for CD19, CD79α, Bcl-2 (~92%) and c-Myc (~50%), while showing negative results for CD20, CD138, programmed cell death protein 1 (PD-1) and programmed cell death receptor 1 ligand 1 (PD-L1). The Ki-67 proliferation index was >80%. In the tumor microenvironment, <10% of the tumor-associated macrophages expressed PD-L1. The number of PD-1-positive tumor-infiltrating lymphocytes was 30-40 cells according to high-power field microscopy. The patient's disease progressed during methotrexate-based treatment, leading to a change in the treatment regimen to the Bruton tyrosine kinase inhibitor, zanubrutinib, combined with the anti-PD-1 monoclonal antibody tislelizumab. After two courses of the combined treatment, the patient achieved complete remission (CR) and continued to receive consolidation treatment. In the 20 months of follow-up since CR was achieved, the patient's general condition was good and the disease was in continuous remission. The present case report and literature review show that a combination of drugs targeting different mechanisms may be used to treat PCNSL to prolong patient survival time. The mechanism of the enhanced efficacy of a combination of the two drugs may be related to the enhancement of antitumor T-cell immune responses and reversal of T-cell immune metabolic dysfunctions by the inhibition of glycolysis.

Cancer Control 2022; 29:10732748221140694. [PMID: 36748438 PMCID: PMC9679352 DOI: 10.1177/10732748221140694] [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] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND The clinical efficacy of immune checkpoint inhibitors (CPIs) has been proven; however, it is also known that their efficacy as monotherapy is limited, with a response rate of 20% or less in solid tumors. The combination of CPIs and anticancer agents has been actively attempted in solid tumors area. In this systematic review and meta-analysis, we aimed to find favorable combination therapies of programmed death 1 (PD-1) or programmed death ligand 1 (PD-L1) inhibitors in terms of anti-tumor efficacy in clinical settings. METHODS An electronic database search was performed using ClinicalTrials.gov, PubMed, and ASCO/ESMO annual meeting libraries. We included randomized or non-randomized trials designed to evaluate the efficacy and safety of combination therapies of PD-1/PD-L1 inhibitors and other anticancer drug-containing therapies. All clinical studies selected were solid tumors with objective response rate (ORR) data. The quality of the evidence was assessed with the Cochrane risk of bias tool or the Newcastle-Ottawa Scale. Meta-analysis used random effects models to pool results. RESULTS Sixteen studies involving 3793 patients were included in the primary analysis. These studies have a monotherapy group with PD-1/PD-L1 inhibitors as the control group or the in-study arm/cohort (1863 patients in the combination group with PD-1/PD-L1 inhibitors and 1930 patients in PD-1/PD-L1 inhibitor monotherapy). The pooled results showed that the combination of PD-1/PD-L1 inhibitors and other anticancer drugs significantly improved the ORR (relative risk [RR] = 1.79, 95% confidence interval [CI] 1.46, 2.20). In the subgroup analysis, PD-1/PD-L1 inhibitor plus DNA-synthesis or microtubule inhibitor led to a statistically significant improvement in the ORR compared to PD-1/PD-L1 inhibitor alone. CONCLUSIONS It was suggested that combinations of PD-1/PD-L1 inhibitors and potential immunogenic cell death (ICD) inducers improve the clinical anti-tumor efficacy, although updated meta-analyses based on the results of ongoing clinical trials are further needed.

Abstract
Myeloid-derived suppressor cells (MDSCs) are a heterogeneous cell population with potent suppressive and regulative properties. MDSCs’ strong immunosuppressive potential creates new possibilities to treat chronic inflammation and autoimmune diseases or induce tolerance towards transplantation. Here, we summarize and critically discuss different pharmacological approaches which modulate the generation, activation, and recruitment of MDSCs in vitro and in vivo, and their potential role in future immunosuppressive therapy.

Abstract
Immune checkpoint blockade (ICB) has become a promising therapy for multiple cancers. However, only a small proportion of patients display a limited antitumor response. The present study aimed to classify distinct immune subtypes and investigate the tumor microenvironment (TME) of urothelial carcinoma, which may help to understand treatment failure and improve the immunotherapy response. RNA-seq data and clinical parameters were obtained from TCGA-BLCA, E-MTAB-4321, and IMVigor210 datasets. A consensus cluster method was used to distinguish different immune subtypes of patients. Infiltrating immune cells, TME signatures, immune checkpoints, and immunogenic cell death modulators were evaluated in distinct immune subtypes. Dimension reduction analysis was performed to visualize the immune status of urothelial carcinoma based on graph learning. Weighted gene co-expression network analysis (WGCNA) was performed to obtain hub genes to predict responses after immunotherapy. Patients with urothelial carcinoma were classified into four distinct immune subtypes (C1, C2, C3 and C4) with various types of molecular expression, immune cell infiltration, and clinical characteristics. Patients with the C3 immune subtype displayed abundant immune cell infiltrations in the tumor microenvironment and were typically identified as “hot” tumor phenotypes, whereas those with the C4 immune subtype with few immune cell infiltrations were identified as “cold” tumor phenotypes. The immune-related and metastasis-related signaling pathways were enriched in the C3 subtype compared to the C4 subtype. In addition, tumor mutation burden, inhibitory immune checkpoints, and immunogenic cell death modulators were highly expressed in the C3 subtype. Furthermore, patients with the C4 subtype had a better probability of overall survival than patients with the C3 subtype in TCGA-BLCA and E-MTAB-4321 cohorts. Patients with the C1 subtype had the best prognosis when undergoing anti-PD-L1 antibody treatment. Finally, the immune landscape of urothelial carcinoma showed the immune status in each patient, and TGFB3 was identified as a potential biomarker for the prediction of immunotherapy resistance after anti-PD-L1 monoclonal antibody treatment. The present study provided a bioinformatics basis for understanding the immune landscape of the tumor microenvironment of urothelial carcinoma.

Abstract
Myeloid-derived suppressor cells (MDSCs) are a heterogeneous population of immature myeloid cells that are activated under pathological conditions, such as cancer, or mature myeloid cells that are converted immune-suppressive cells via tumor-derived exosomes, and potently support the tumor processes at different levels. Currently, multiple studies have demonstrated that MDSCs induce immune checkpoint blockade (ICB) therapy resistance through their contribution to the immunosuppressive network in the tumor microenvironment. In addition, non-immunosuppressive mechanisms of MDSCs such as promotion of angiogenesis and induction of cancer stem cells also exert a powerful role in tumor progression. Thus, MDSCs are potential therapeutic targets to enhance the antitumor efficacy of ICB therapy in cases of multiple cancers. This review focuses on the tumor-promoting mechanism of MDSCs and provides an overview of current strategies that target MDSCs with the objective of enhancing the antitumor efficacy of ICB therapy.

A phase 2 trial of avelumab in men with aggressive-variant or neuroendocrine prostate cancer. Prostate Cancer Prostatic Dis 2022; 25:762-769. [PMID: 35292724 PMCID: PMC8923335 DOI: 10.1038/s41391-022-00524-7] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Revised: 02/20/2022] [Accepted: 03/02/2022] [Indexed: 01/14/2023]
Abstract
BACKGROUND Men with progressive neuroendocrine or aggressive-variant metastatic prostate cancer (NEPC/AVPC) have a poor prognosis and limited treatment options, and immunotherapy has not been tested in such patients. METHODS We conducted an open label single center phase 2 trial (NCT03179410) of men with progressive NEPC/AVPC either defined by histology or AVPC criteria. Avelumab (10 mg/kg every 2 weeks) was administered until progression or unacceptable toxicity. The primary endpoint was overall response rate (ORR). Secondary endpoints included ORR, radiographic progression-free survival (rPFS), overall survival, and safety. Correlative studies included longitudinal peripheral blood immune phenotyping. The study was limited by the small number of patients enrolled and by the early termination due to COVID-19. RESULTS A total of 15 men with AVPC/NEPC were enrolled. The median age was 71 (range 51-85 years), and men had received a median of two prior therapies (range 1-3). Median PSA was 54 ng/dl (range 0-393), and 73% of men had liver metastasis. The ORR with avelumab in this setting by iRECIST or RECIST 1.1 was 6.7%, including one patient (6.7%) with a complete remission (CR), 20% with stable disease, and 67% with progressive disease. The patient with the CR had an MSH2 somatic mutation and MSI-high NEPC with central nervous system metastases, and his CR remains durable off all therapy for 2 years. The median rPFS was 1.8 months (95% CI 1.6-3.6 months), and median overall survival was 7.4 months (85% CI 2.8-12.6 months). Safety was consistent with the known profile of avelumab. Phenotyping of peripheral immune subsets suggest enhanced CXCR2-dependent myeloid and T-cell responses in this extraordinary responder. CONCLUSIONS While the study was terminated early due to slow enrollment at the onset of the COVID-19 pandemic and lower than anticipated objective response rate, PD-L1 inhibition with avelumab monotherapy showed poor efficacy in patients with microsatellite stable NEPC/AVPC. Immune profiling revealed enhanced CXCR2 positive immune cell activation in the one extraordinary responder, suggesting potential mechanisms for further immunotherapy development in this population.

Abstract
The BTK inhibitors ibrutinib and acalabrutinib are FDA-approved drugs for the treatment of B cell malignances. Both drugs have demonstrated clinical efficacy and safety profiles superior to chemoimmunotherapy regimens in patients with chronic lymphocytic leukemia. Mounting preclinical and clinical evidence indicates that both ibrutinib and acalabrutinib are versatile and have direct effects on many immune cell subsets as well as other cell types beyond B cells. The versatility and immunomodulatory effects of both drugs have been exploited to expand their therapeutic potential in a wide variety of human diseases. Over 470 clinical trials are currently registered at ClinicalTrials.gov to test the efficacy of ibrutinib or acalabrutinib not only in almost every type of B cell malignancies, but also in hematological malignancies of myeloid cells and T cells, solid tumors, chronic graft versus host disease (cGHVD), autoimmune diseases, allergy and COVID-19 (http:www.clinicaltrials.gov). In this review, we present brief discussions of the clinical trials and relevant key preclinical evidence of ibrutinib and acalabrutinib as monotherapies or as part of combination therapies for the treatment of human diseases beyond B cell malignancies. Adding to the proven efficacy of ibrutinib for cGVHD, preliminary results of clinical trials have shown promising efficacy of ibrutinib or acalabrutinib for certain T cell malignancies, allergies and severe COVID-19. However, both BTK inhibitors have no or limited efficacy for refractory or recurrent solid tumors. These clinical data together with additional pending results from ongoing trials will provide valuable information to guide the design and improvement of future trials, including optimization of combination regimens and dosing sequences as well as better patient stratification and more efficient delivery strategies. Such information will further advance the precise implementation of BTK inhibitors into the clinical toolbox for the treatment of different human diseases.

Multifaceted Immunomodulatory Effects of the BTK Inhibitors Ibrutinib and Acalabrutinib on Different Immune Cell Subsets - Beyond B Lymphocytes. Front Cell Dev Biol 2021; 9:727531.

Abstract
The clinical success of the two BTK inhibitors, ibrutinib and acalabrutinib, represents a major breakthrough in the treatment of chronic lymphocytic leukemia (CLL) and has also revolutionized the treatment options for other B cell malignancies. Increasing evidence indicates that in addition to their direct effects on B lymphocytes, both BTK inhibitors also directly impact the homeostasis, phenotype and function of many other cell subsets of the immune system, which contribute to their high efficacy as well as adverse effects observed in CLL patients. In this review, we attempt to provide an overview on the overlapping and differential effects of ibrutinib and acalabrutinib on specific receptor signaling pathways in different immune cell subsets other than B cells, including T cells, NK cells, monocytes, macrophages, granulocytes, myeloid-derived suppressor cells, dendritic cells, osteoclasts, mast cells and platelets. The shared and distinct effects of ibrutinib versus acalabrutinib are mediated through BTK-dependent and BTK-independent mechanisms, respectively. Such immunomodulatory effects of the two drugs have fueled myriad explorations of their repurposing opportunities for the treatment of a wide variety of other human diseases involving immune dysregulation.

Abstract
Urothelial carcinoma is one of the most common cancers in the United States, yet outcomes are historically suboptimal. Since 2016, the approval of five programmed cell death 1 and programmed death-ligand 1 immune checkpoint inhibitors for locally advanced and metastatic urothelial carcinoma has led to improved oncologic outcomes for many patients in the second-line setting. Two checkpoint inhibitors, pembrolizumab and atezolizumab subsequently earned approval for first-fine therapy with restricted indications. More recently, pembrolizumab was approved for bacillus Calmette-Guérin-unresponsive high-risk non-muscle invasive bladder cancer, opening the door for other immune checkpoint inhibitors to be integrated into treatment in earlier disease stages. Recent bacillus Calmette-Guérin shortages have highlighted the need for alternative treatment options for patients with non-muscle invasive bladder cancer. Currently, there are no FDA-approved checkpoint inhibitors for non-metastatic muscle-invasive bladder cancer. Furthermore, many patients are ineligible for standard cisplatin-based chemotherapy regimens. Numerous ongoing clinical trials are employing immune checkpoint inhibitors for muscle-invasive bladder cancer patients in the neoadjuvant, adjuvant, perioperative, and bladder-sparing setting. Although up to 10% of urothelial carcinoma tumors arise in the upper urinary tract, few studies are designed for this population. We highlight the need for more trials designed for patients with upper tract disease. Overall, there are numerous clinical trials investigating the safety and efficacy of immune checkpoint inhibitors in all stages of disease as single-agents and combined with dual-immune checkpoint inhibition, chemotherapy, radiotherapy, and other pharmacologic agents. As the field continues to evolve rapidly, we aim to provide an overview of recent and ongoing immunotherapy clinical trials in urothelial carcinoma.

Abstract
Simple Summary Protein tyrosine kinase BTK is essential for B cell maturation and proliferation. Dysregulation of BTK signaling in B cells leads to B cell lymphoma. In addition to B cells, BTK is also expressed in other types of immune cells including MDSC, dendritic cells, mast cells and macrophages, all of which comprise the tumor microenvironment in solid cancers. Although BTK inhibitors have been FDA-approved as the front-line treatment for B cell malignancy CLL/SLL, studies have been reluctant to report on BTKs role within the tumor microenvironment during solid cancer development limiting the possibility of using these BTK inhibitors as an adjuvant treatment option for solid cancers. Here, we review BTK signaling within the cells found in the tumor microenvironment as well as summarizing clinical trials using BTK inhibitors which target the tumor microenvironment in an attempt to combat solid tumors. Abstract The cell environment plays a pivotal role in determining cellular outcome, as well as cancer initiation, progression, and dissemination. Within this environment, in addition to the structural components, such as the extracellular matrix, there are various types of cells surrounding the tumor cells. Communication among these cells and the tumor cells via signaling pathways is important for tumor growth. Originally discovered in patients with immunodeficiency X-linked gammaglobulinemia, the Bruton’s tyrosine kinase (BTK) signaling pathway, known for its role in B cell maturation, is critical to cancer cell proliferation, metastasis and evasion of cancer eliminating cells. Given that BTK inhibitors have been FDA approved for chronic lymphocytic leukemia/small lymphocytic lymphoma and that the majority of BTK studies have been focused on B cells, the use of BTK inhibitors as a future treatment strategy of solid tumors has yet to be evaluated. In this review, we summarize studies analyzing BTK signaling within the cells found in the tumor microenvironment, as well as clinical trial where BTK inhibitors are currently being used to target the tumor microenvironment as a way to combat solid tumors.

Abstract
The repurposing of FDA-approved Bruton's tyrosine kinase (BTK) inhibitors as therapeutic agents for solid tumors may offer renewed hope for chemotherapy-resistant cancer patients. Here we review the emerging evidence regarding the clinical potential of BTK inhibitors in solid tumor therapy. The use of BTK inhibitors may through lead optimization and translational research lead to the development of new and effective combination regimens for metastatic and/or therapy-refractory solid tumor patients.

Abstract
Simple Summary The genetic adaptability of malignant cells and their consequent heterogeneity even within the same patient poses a great obstacle to cancer patient treatment. This review summarizes the data obtained in the last decade on different preclinical mice models as well as on various immunotherapeutic clinical trials in distinct solid and hematopoietic cancers on how the immune system can be implemented in tumor therapy. Moreover, the different intrinsic and extrinsic escape strategies utilized by the tumor to avoid elimination by the immune system are recapitulated together with the different approaches proposed to overcome them in order to succeed and/or to enhance therapy efficacy. Abstract Immune therapy approaches such as checkpoint inhibitors or adoptive cell therapy represent promising therapeutic options for cancer patients, but their efficacy is still limited, since patients frequently develop innate or acquired resistances to these therapies. Thus, one major goal is to increase the efficiency of immunotherapies by overcoming tumor-induced immune suppression, which then allows for immune-mediated tumor clearance. Innate resistance to immunotherapies could be caused by a low immunogenicity of the tumor itself as well as an immune suppressive microenvironment composed of cellular, physical, or soluble factors leading to escape from immune surveillance and disease progression. So far, a number of strategies causing resistance to immunotherapy have been described in various clinical trials, which broadly overlap with the immunoediting processes of cancers. This review summarizes the novel insights in the development of resistances to immune therapy as well as different approaches that could be employed to overcome them.

Abstract
Background Inhibition of the programmed cell death protein 1 (PD‐1) pathway has demonstrated clinical benefit in metastatic urothelial cancer (mUC); however, response rates of 15% to 26% highlight the need for more effective therapies. Bruton tyrosine kinase (BTK) inhibition may suppress myeloid‐derived suppressor cells (MDSCs) and improve T‐cell activation. Methods The Randomized Phase 2 Trial of Acalabrutinib and Pembrolizumab Immunotherapy Dual Checkpoint Inhibition in Platinum‐Resistant Metastatic Urothelial Carcinoma (RAPID CHECK; also known as ACE‐ST‐005) was a randomized phase 2 trial evaluating the PD‐1 inhibitor pembrolizumab with or without the BTK inhibitor acalabrutinib for patients with platinum‐refractory mUC. The primary objectives were safety and objective response rates (ORRs) according to the Response Evaluation Criteria in Solid Tumors, version 1.1. Secondary endpoints included progression‐free survival (PFS) and overall survival (OS). Immune profiling was performed to analyze circulating monocytic MDSCs and T cells. Results Seventy‐five patients were treated with pembrolizumab (n = 35) or pembrolizumab plus acalabrutinib (n = 40). The ORR was 26% with pembrolizumab (9% with a complete response [CR]) and 20% with pembrolizumab plus acalabrutinib (10% with a CR). The grade 3/4 adverse events (AEs) that occurred in ≥15% of the patients were anemia (20%) with pembrolizumab and fatigue (23%), increased alanine aminotransferase (23%), urinary tract infections (18%), and anemia (18%) with pembrolizumab plus acalabrutinib. One patient treated with pembrolizumab plus acalabrutinib had high MDSCs at the baseline, which significantly decreased at week 7. Overall, MDSCs were not correlated with a clinical response, but some subsets of CD8+ T cells did increase during the combination treatment. Conclusions Both treatments were generally well tolerated, although serious AE rates were higher with the combination. Acalabrutinib plus pembrolizumab did not improve the ORR, PFS, or OS in comparison with pembrolizumab alone in mUC. Baseline and on‐treatment peripheral monocytic MDSCs were not different in the treatment cohorts. Proliferating CD8+ T‐cell subsets increased during treatment, particularly in the combination cohort. Ongoing studies are correlating these peripheral immunome findings with tissue‐based immune cell infiltration. In this randomized phase 2 study of metastatic urothelial cancer, a combination of pembrolizumab and a Bruton tyrosine kinase inhibitor (acalabrutinib) does not improve clinical outcomes in comparison with pembrolizumab alone. Comprehensive flow cytometry is used to evaluate circulating immune cells during treatment.
