Targeting microRNAs as a promising anti-cancer therapeutic strategy against traffic-related air pollution-mediated lung cancer. Cancer Metastasis Rev 2024; 43:657-672. [PMID: 37910296 DOI: 10.1007/s10555-023-10142-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Accepted: 09/25/2023] [Indexed: 11/03/2023]
Abstract
Air pollutants are increasingly emitted into the atmosphere because of the high dependency of humans on fossil-derived fuels. Wind speed and direction assisted high dispersibility and uncontrolled nature of air pollution across geo-/demographical borders, making it one of the major global concerns. Besides climate change, air pollution has been found to be associated with various diseases, such as cancer. Lung cancer, which is the world's most common type of cancer, has been found to be associated with traffic-related air pollution. Research and political efforts have been taken to explore green/renewable energy sources. However, these efforts at the current intensity cannot cope with the increasing need for fossil fuels. More specifically, political tensions such as the Russian-Ukraine war, economic tension (e.g., China-USA economic tensions), and other issues (e.g., pandemic, higher inflation rate, and poverty) significantly hindered phasing out fossil fuels. In this context, an increasing global population will be exposed to traffic-related air pollution, which justifies the current uptrend in the number of lung cancer patients. To combat this health burden, novel treatments with higher efficiency and specificity must be designed. One of the potential "life changer" options is microRNA (miRNA)-based therapy to target the expression of oncogenic genes. That said, this review discusses the association of traffic-related air pollution with lung cancer, the changes in indigenous miRNAs in the body during lung cancer, and the current status of miRNA therapeutics for lung cancer treatment. We believe that the article will significantly appeal to a broad readership of oncologists, environmentalists, and those who work in the field of (bio)energy. It may also gain the policymakers' attention to establish better health policies and regulations about air pollution, for example, by promoting (bio)fuel exploration, production, and consumption.

TROP2 Is Associated with Primary Resistance to Immune Checkpoint Inhibition in Patients with Advanced Non-Small Cell Lung Cancer. Clin Cancer Res 2024; 30:779-785. [PMID: 38048058 PMCID: PMC10870116 DOI: 10.1158/1078-0432.ccr-23-2566] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 10/07/2023] [Accepted: 11/29/2023] [Indexed: 12/05/2023]
Abstract
PURPOSE Mechanisms of primary resistance to inhibitors of the programmed cell death-1 (PD-1)/programmed death-ligand 1 (PD-L1) signaling axis in non-small cell lung cancer (NSCLC) are still poorly understood. While some studies suggest the involvement of trophoblast cell surface antigen 2 (TROP2) in modulating tumor cell resistance to therapeutic drugs, its specific role in the context of PD-1/PD-L1 axis blockade is not definitively established. EXPERIMENTAL DESIGN We performed high-throughput analysis of transcriptomic data from 891 NSCLC tumors from patients treated with either the PD-L1 inhibitor atezolizumab or chemotherapy in two large randomized clinical trials. To confirm our results at the protein level, we complemented this transcriptional approach by performing a multiplex immunofluorescence analysis of tumor tissue samples as well as a proteomic profiling of plasma. RESULTS We observed a significant association of TROP2 overexpression with worse progression-free survival and overall survival on PD-L1 blockade, independent of other prognostic factors. Importantly, we found increased TROP2 expression to be predictive of survival in patients treated with atezolizumab but not chemotherapy. TROP2 overexpression was associated with decreased T-cell infiltration. We confirmed these results at the proteomic level both on tumor tissue and in plasma. CONCLUSIONS Our results suggest an important contribution of TROP2 expression to the primary resistance to PD-L1 blockade in NSCLC. TROP2-biomarker-based strategy may be relevant in selecting patients with NSCLC who are more likely to benefit from a combination of immunotherapy and an anti-TROP2 agent.

Abstract
PURPOSE This first-in-human, dose-escalation and dose-expansion study evaluated the safety, tolerability, and antitumor activity of datopotamab deruxtecan (Dato-DXd), a novel trophoblast cell-surface antigen 2 (TROP2)-directed antibody-drug conjugate in solid tumors, including advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Adults with locally advanced/metastatic NSCLC received 0.27-10 mg/kg Dato-DXd once every 3 weeks during escalation or 4, 6, or 8 mg/kg Dato-DXd once every 3 weeks during expansion. Primary end points were safety and tolerability. Secondary end points included objective response rate (ORR), survival, and pharmacokinetics. RESULTS Two hundred ten patients received Dato-DXd, including 180 in the 4-8 mg/kg dose-expansion cohorts. This population had a median of three prior lines of therapy. The maximum tolerated dose was 8 mg/kg once every 3 weeks; the recommended dose for further development was 6 mg/kg once every 3 weeks. In patients receiving 6 mg/kg (n = 50), median duration on study, including follow-up, and median exposure were 13.3 and 3.5 months, respectively. The most frequent any-grade treatment-emergent adverse events (TEAEs) were nausea (64%), stomatitis (60%), and alopecia (42%). Grade ≥3 TEAEs and treatment-related AEs occurred in 54% and 26% of patients, respectively. Interstitial lung disease adjudicated as drug-related (two grade 2 and one grade 4) occurred in three of 50 patients (6%). The ORR was 26% (95% CI, 14.6 to 40.3), and median duration of response was 10.5 months; median progression-free survival and overall survival were 6.9 months (95% CI, 2.7 to 8.8 months) and 11.4 months (95% CI, 7.1 to 20.6 months), respectively. Responses occurred regardless of TROP2 expression. CONCLUSION Promising antitumor activity and a manageable safety profile were seen with Dato-DXd in heavily pretreated patients with advanced NSCLC. Further investigation as first-line combination therapy in advanced NSCLC and as monotherapy in the second-line setting and beyond is ongoing.

Abstract
INTRODUCTION Lung cancer is the second most common cancer in the world and the leading cause of cancer-related mortality. Immune checkpoint inhibitors (ICIs), as monotherapy or in combination with platinum-based chemotherapy, have emerged as the standard of care first-line treatment option for patients with advanced non-small cell lung cancer (NSCLC) without actionable genomic alterations (AGAs). Despite significant improvements in patient outcomes with these regimens, primary or acquired resistance is common and most patients develop disease progression, resulting in poor survival. AREAS COVERED We review the current treatments commonly used for NSCLC without AGAs in the first-line and subsequent settings and describe the unmet needs for these patients in the second-line setting, including a lack of standard definitions for primary and required resistance, and few effective treatment options for patients who develop progression of their disease on first-line therapy. We describe key mechanisms of resistance to ICIs and emerging therapies that are being investigated for patients who develop progression on ICIs and platinum-based chemotherapy. EXPERT OPINION Emerging agents in development have a variety of different mechanisms of action and will likely change standard of care for second-line therapy and beyond for patients with NSCLC without AGAs in the future.

Abstract
Pembrolizumab monotherapy is a standard first-line treatment for PD-L1-high advanced non-small-cell lung cancer (NSCLC) without actionable genomic alterations (AGA). However, few patients experience long-term disease control, highlighting the need for more effective therapies. Datopotamab deruxtecan (Dato-DXd), a novel trophoblast cell-surface antigen 2-directed antibody-drug conjugate, showed encouraging safety and antitumor activity with pembrolizumab in advanced NSCLC. We describe the rationale and design of TROPION-Lung08, a phase III study evaluating safety and efficacy of first-line Dato-DXd plus pembrolizumab versus pembrolizumab monotherapy in patients with advanced/metastatic NSCLC without AGAs and with PD-L1 tumor proportion score ≥50%. Primary end points are progression-free survival and overall survival; secondary end points include objective response rate, duration of response, safety and presence of antidrug antibodies. Clinical trial registration: NCT05215340 (ClinicalTrials.gov).

Cancer Treat Rev 2023; 118:102572. [PMID: 37230055 DOI: 10.1016/j.ctrv.2023.102572] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2023] [Revised: 05/03/2023] [Accepted: 05/11/2023] [Indexed: 05/27/2023]
Abstract
BACKGROUND Antibody drug conjugates (ADCs) represent a revolutionary drug class in cancer therapy, combining the precision of targeted therapy with the cytotoxic effects of chemotherapy. Promising activity of novel ADCs, namely Trastuzumab Deruxtecan and Patritumab Deruxtecan, has been observed in hard-to treat molecular subtypes, such as HER2-positive and heavily pretreated EGFR-mutant Non-Small Cell Lung Cancer (NSCLC). However, therapeutic advances are expected in certain subgroups of lung cancer patients, including non-oncogene-addicted NSCLC after failure of current standard of care (e.g., immunotherapy with or without chemotherapy, chemo-antiangiogenic treatment). Trophoblastic Cell Surface Antigen 2 (TROP-2) is a surface transmembrane glycoprotein member of the epithelial cell adhesion molecule (EpCAM) family. TROP-2 represents a promising therapeutic target in refractory non-oncogene-addicted NSCLC. METHODOLOGY We performed a systematic literature search of the clinical trials about TROP-2 directed ADCs in NSCLC referenced in the pubmed.gov database, Cochrane Library database and clinicaltrial.gov database. RESULTS First-in-humans ADCs targeting TROP-2, namely Sacituzumab Govitecan (SN-38) and Datopotamab Deruxtecan (Dxd), yielded promising activity signals in NSCLC with a manageable safety profile. Most common grade ≥ 3 adverse events (AEs) of Sacituzumab Govitecan included neutropenia (28 %), diarrhea (7 %), nausea (7 %), fatigue (6 %), and febrile neutropenia (4 %). Nausea and stomatitis were the most common all grade AEs with Datopotamab Deruxtecan; dyspnea, amylase increase, hyperglycemia and lymphopenia were reported as grade ≥ 3 AEs in less than 12 % of patients. CONCLUSION As more effective strategies are needed for patients with refractory non-oncogene-addicted NSCLC, the design of novel clinical trials with ADCs targeting TROP-2 is encouraged as both a monotherapy or combination strategy with existing agents (e.g., monoclonal antibodies targeting immune checkpoint inhibitors or chemotherapy).

Abstract
The discovery of activating mutations in epidermal growth factor receptor (EGFR) in non-small-cell lung cancer transformed the care and prognosis of patients and heralded the era of 'personalized medicine' in thoracic oncology. Osimertinib, a third-generation EGFR inhibitor, has been established as the preferred EGFR inhibitor for newly diagnosed patients which urged the need to develop treatment options for patients progressing on first-line osimertinib. However, acquired resistance invariably emerges and numerous efforts have been attempted to delay or overcome acquired resistance. In this article, we thoroughly reviewed the current understanding of osimertinib resistance mechanisms and explored the established and emerging treatment options. Newer treatment strategies targeting EGFR-dependent or -independent resistance mechanisms, novel approaches using bispecific antibodies and antibody-drug conjugates will be discussed. Moreover, what to do with brain only progression, and how to incorporate immunotherapy in EGFR-mutant lung cancer will be discussed. Lastly, future perspectives on the ongoing clinical trials and combination of front-line therapy will be introduced.

Abstract
PURPOSE OF REVIEW Antibody-drug conjugates (ADCs) are a class of therapeutics that combine target-specific monoclonal antibodies with cytotoxic chemotherapy. Here, we describe the components of ADCs and review their promising activity, safety, and applicability in non-small cell lung cancer (NSCLC). RECENT FINDINGS Technological advancements have reinvigorated ADCs as a viable treatment strategy in advanced solid tumors. Several target-specific ADCs have shown promise in treatment-refractory NSCLC, including agents targeting HER2, HER3, TROP2, CEACAM5, and MET, among others, with multiple confirmatory phase 3 trials ongoing. Critically, ADCs have demonstrated efficacy signals in both driver mutation-positive and mutation-negative advanced NSCLC, reinforcing their potential as an efficacious treatment strategy that transcends diverse tumor biology in advanced NSCLC. ADCs are a promising class of anti-cancer therapeutics that have significant potential in advanced NSCLC. Beyond confirmatory phase 3 trials, several questions remain including optimal agent sequencing, combinatorial methods, and unique toxicity management.

Abstract
Trop2 is a transmembrane glycoprotein and calcium signal transducer with limited expression in normal human tissues. It is consistently overexpressed in a variety of malignant tumors and participates in several oncogenic signaling pathways that lead to tumor development, invasion, and metastasis. As a result, Trop2 has become an attractive therapeutic target in cancer treatment. The anti-Trop2 antibody-drug conjugate (Trodelvy™, sacituzumab govitecan) has been approved to treat metastatic triple-negative breast cancer. However, it is still unclear whether the success observed in Trop2-positive breast cancer could be replicated in other tumor types, owing to the differences in the expression levels and functions of Trop2 across cancer types. In this review, we summarize the recent progress on the structures and functions of Trop2 and highlight the potential diagnostic and therapeutic value of Trop2 beyond breast cancer. In addition, the promising novel Trop2-targeted agents in the clinic were discussed, which will likely alter the therapeutic landscape of Trop2-positive tumors in the future.

Abstract
Despite therapeutic advances, the prognosis of non-small cell lung cancers (NSCLC) is still very poor, especially when first diagnosed at later stages involving metastases. NSCLC classification can be aided by identifying genetic, molecular, and histological subtypes that are important biomarkers in treatment selection. The majority of targeted therapies are now first-line treatment options for eligible patients with advanced stages of NSCLC. Here they have been shown to improve overall survival (OS) and progression free survival (PFS). Such treatments include those aimed at driver mutations in NSCLC, such as the genes for EGFR and ALK, and immune checkpoint inhibitors such as those targeting programmed death protein 1 or its ligand (programmed death ligand 1 [PD-L1]). In antibody-drug conjugates (ADC), cytotoxic payloads are conjugated to monoclonal antibodies (mAb) that deliver the drug to tumour cells expressing the corresponding target antigen. While there are still no ADCs specifically approved for NSCLC by the U.S. Food and Drugs Administration (FDA), several agents have shown promise and are being investigated as therapy in NSCLC. Emerging biomarkers as targets for ADCs with potential relevance in the treatment of NSCLC include products of the genes CEACAM5, TROP2, HER2, and c-MET. Herein, this interview provides an overview of biomarkers and targeted therapies, with a discussion with Grace Dy, Roswell Park Comprehensive Cancer Center, Buffalo, New York, USA, on their potential clinical utility.

Abstract
BACKGROUND Trophoblast cell surface antigen 2 (TROP2) has unclear clinical role in oral squamous cell carcinomas (OSCC). Here, we investigated the association of TROP2 immunoexpression with clinicopathological parameters and survival of OSCC patients. SUBJECTS AND METHODS Cancer-specific survival (CSS) and disease-free survival (DFS) were assessed in a cohort composed of 266 OSCC. An independent cohort with 88 OSCC samples matched with the normal oral tissue, as well as 17 metastatic lymph nodes, was used for validation. RESULTS Multivariate analysis showed TROP2 as an independent marker of favorable prognosis for both CSS (HR: 0.60, 95% CI: 0.40-0.90, p = .01) and DFS (HR: 0.57, 95% CI: 0.36-0.89, p = .01). Furthermore, TROP2 protein expression was significantly higher in morphologically normal tissues compared to primary tumors (p < .0001) and lymph node metastases (p = .001), and it was significantly associated with CSS (HR: 0.26, 95% CI: 0.09-0.74, p = .008) in the validation cohort. A pooled mRNA analysis performed on the Oncomine™ database confirmed the underexpression in OSCC compared with normal tissues (p = .014). CONCLUSIONS In summary, our results point to a favorable prognostic significance of TROP2 overexpression in a large cohort of oral cancer patients, suggesting it as an attractive clinical marker.

Abstract
Trophoblast cell surface antigen 2 (Trop2) is a widely expressed glycoprotein and an epithelial cell adhesion molecule (EpCAM) family member. Although initially identified as a transmembrane protein, other subcellular localizations and processed forms were described. Its congenital mutations cause a gelatinous drop-like corneal dystrophy, a disease characterized by loss of barrier function in corneal epithelial cells. Trop2 is considered a stem cell marker and its expression associates with regenerative capacity in various tissues. Trop2 overexpression was described in tumors of different origins; however, functional studies revealed both oncogenic and tumor suppressor roles. Nevertheless, therapeutic potential of Trop2 was recognized and clinical studies with drug-antibody conjugates have been initiated in various cancer types. One of these agents, sacituzumab govitecan, has been recently granted an accelerated approval for therapy of metastatic triple-negative breast cancer. In this article, we review the current knowledge about the yet controversial function of Trop2 in homeostasis and pathology.
