Spotlight on afatinib and its potential in the treatment of squamous cell lung cancer: the evidence so far.

ABSTRACT: Compared to adenocarcinoma, fewer effective treatment options are available for advanced or metastatic squamous cell carcinoma (SCC) of the lung. Afatinib is an orally administered, irreversible EGFR antagonist. As a second-generation tyrosine kinase inhibitor, it has been applied in the treatment of patients with EGFR-mutant non-small-cell lung cancer. Recently, several clinical trials have shown that afatinib leads to a significant improvement in progression-free survival and overall survival of patients with SCC. Moving forward, afatinib should be one of the options among tyrosine kinase inhibitors, monoclonal antibodies, and cytotoxicity chemotherapy drugs for SCC.

New developments in the treatment of advanced squamous cell lung cancer: focus on afatinib.

Project description:Until recently, few treatment options existed for the treatment of squamous cell carcinoma (SqCC) of the lung, especially in the second-line setting following platinum-based chemotherapy. Accordingly, outcomes in this subtype of non-small-cell lung cancer (NSCLC) were generally poor. In this context, the recent availability of the checkpoint inhibitors nivolumab and pembrolizumab, the anti-VEGFR2 antibody ramucirumab (combined with docetaxel), and the ErbB-family blocker afatinib for the treatment of relapsed/refractory SqCC of the lung represent major advances. However, the rapid expansion of the treatment armamentarium invites many questions regarding optimal treatment choice and sequence in individual patients. This review focuses on the biologic rationale and clinical evidence to support the use of afatinib in this treatment setting, highlighting the prominent role of the ErbB-signaling cascade in SqCC tumors. The seminal Phase III LUX-Lung 8 study, on which the approval of afatinib is based, is discussed and contextualized with the emergence of immunotherapies. Finally, criteria are explored that might drive physicians' treatment decisions when considering the use of afatinib based on individual patient characteristics. Other ongoing developments in the treatment of SqCC of the lung that will lead to further options and welcome improvements in the management of this difficult-to-treat disease are summarized.

Development of treatment options for Chinese patients with advanced squamous cell lung cancer: focus on afatinib.

Project description:Lung cancer is the leading cause of cancer death in China, and approximately one third of these cancers are squamous cell carcinoma (SqCC) of the lung. Ethnic diversity and country-specific environmental factors can account for interindividual variations in response to and tolerability of anticancer therapies. Although several targeted therapies have recently been approved for patients with relapsed/refractory SqCC of the lung, only afatinib, an irreversible ErbB family blocker, has data of Chinese patients. In the Phase III LUX-Lung 8 trial, afatinib demonstrated a significant clinical benefit vs the reversible first-generation EGFR tyrosine kinase inhibitor erlotinib in both the overall population and the Chinese subset, with a manageable safety profile. Emerging biomarker data from LUX-Lung 8 suggest that patients with ErbB mutations, especially ErbB2, and those classified as "good" in the VeriStrat® proteomic test, may benefit from afatinib treatment in particular, regardless of ethnicity, and may get a long-term response. In conclusion, afatinib is a valid second-line option for Chinese patients with SqCC of the lung, and specific biomarkers may help guide in treatment decision-making. Ongoing studies will provide further guidance on afatinib's place in the treatment algorithm, alongside the other novel targeted therapies.

Afatinib treatment in advanced non-small cell lung cancer.

Project description:Despite some recent advances in the management of advanced non-small cell lung cancer (NSCLC), prognosis for these patients remains poor. Small molecule epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have however provided a new therapeutic option in this disease setting and EGFR mutation testing is now routine practice for newly diagnosed NSCLC patients. A proportion of patients will not respond to first-generation EGFR-TKIs however, and those who do will ultimately develop resistance and disease relapse. Next-generation EGFR-TKIs which inhibit multiple members of the EGFR family are being developed in order to increase sensitivity and overcome resistance to existing agents. Afatinib (BIBW 2992) is an oral, irreversible inhibitor of EGFR and HER2 tyrosine kinases and is the most advanced of these agents in clinical development. Pre-clinical and early-phase clinical trials have demonstrated a favorable safety profile as a single agent and in combination with other anti-cancer agents, and provide evidence of clinical activity in advanced NSCLC. The LUX-Lung trials suggest that for selected patients, afatinib offers symptomatic improvement and prolonged progression-free survival, although this has not yet translated into improved overall survival. This article aims to review the use of EGFR-TKIs in the management of advanced NSCLC and the mechanisms underlying resistance to these agents. We will discuss the current pre-clinical and clinical data regarding afatinib, its potential to overcome resistance to first-generation TKIs, and its emerging role in advanced NSCLC treatment.

Afatinib for the treatment of metastatic non-small cell lung cancer.

Project description:Targeting the epidermal growth factor receptor (EGFR) in patients with non-small cell lung cancer (NSCLC) harboring sensitizing mutations in the tyrosine kinase (TKI) domain has led to a significant change in the management of this disease. The classic or sensitizing mutations are G719X mutation in exon 18, in-frame deletions or insertion of exon 19, L858R or L861Q mutation in exon 21. Approximately 90% of these mutations are exon 19 deletion or exon 21 L858R point mutation. Gefitinib and erlotinib are reversible first-generation inhibitors of mutant EGFR, and treatment with these agents in the first-line setting has demonstrated a progression-free survival of 9.5-13.7 months. However, the majority of these patients ultimately develop resistance to these drugs. Afatinib is an irreversible pan-ErbB inhibitor that was developed to circumvent the problem of resistance to first-generation TKIs. The LUX-Lung studies have evaluated the efficacy and toxicities of afatinib in treatment-naïve and refractory NSCLC patients. The promising results of some of these trials led to approval of afatinib by the US Food and Drug Administration for patients with advanced NSCLC and EGFR exon 19 deletions or exon 21 (L858R) substitution mutations. Afatinib causes toxicities similar to those of the first-generation EGFR TKIs, such as diarrhea, rash, acne, and stomatitis, and overall is well tolerated. This article focuses on the clinical studies of afatinib in patients with NSCLC.

Spotlight on pembrolizumab in non-small cell lung cancer: the evidence to date.

Project description:Immunotherapy with immune checkpoint inhibitors has opened a new arena in cancer therapeutics. Pembrolizumab is a highly selective anti-programmed cell death protein 1 (PD-1) antibody that has shown efficacy, leading to survival benefit and durable responses, in some patients with non-small cell lung cancer (NSCLC). It has been approved by the US Food and Drug Administration for the treatment of patients with metastatic NSCLC, whose tumors express PD-1 ligand 1 (PD-L1), with disease progression on or after platinum-containing chemotherapy. Here, we briefly discuss the PD-1/PD-L1 pathway and pembrolizumab before delving into the clinical trials that have led to its just-mentioned approval in NSCLC and ongoing clinical trials. Finally, we discuss the use of biomarkers, primarily PD-L1, in the context of pembrolizumab and NSCLC.

Afatinib vs erlotinib for second-line treatment of Chinese patients with advanced squamous cell carcinoma of the lung.

Project description:Background:The global Phase III LUX-Lung 8 trial (ClinicalTrials.gov: NCT01523587) identified significant improvements in progression-free survival (PFS), overall survival (OS), and patient-reported outcomes (PROs) with second-line afatinib vs erlotinib in patients with advanced squamous cell carcinoma (SCC) of the lung. Materials and methods:We conducted a post hoc analysis of data for patients in LUX-Lung 8 from mainland China (n=67). Compared with erlotinib, afatinib reduced the risk of disease progression or death (PFS) in the Chinese subgroup by 30% (HR=0.70; 95% CI: 0.38-1.27). Results:The risk of death was reduced by 31% (HR=0.69; 95% CI: 0.39-1.21). The proportion of Chinese patients with improvements in PROs also favored afatinib vs erlotinib (global health status/quality of life [QoL], 52.8% vs 29.6%, P=0.072; dyspnea, 47% vs 26%, P=0.091; "dyspnea walked", 44% vs 15%, P=0.017; QoL rate, 53% vs 26%, P=0.037). Discussion:While this analysis was not powered to demonstrate differences compared to the overall trial population (OTP), and there were some differences in baseline characteristics (eg, the proportion of patients aged ?65 years old), the benefits of afatinib treatment in Chinese patients with SCC of the lung appeared to be at least comparable to that observed in LUX-Lung 8. As with the OTP, the most common adverse events (AEs) with afatinib in the Chinese subgroup were diarrhea and rash/acne, and the incidence and type of the most frequently occurring AEs were similar. Conclusion:The results suggest that afatinib represents a feasible treatment option for Chinese patients with advanced SCC of the lung following progression on platinum-based chemotherapy.

Efficacy of Afatinib in the Treatment of Patients with Non-Small Cell Lung Cancer and Head and Neck Squamous Cell Carcinoma: A Systematic Review and Meta-Analysis.

Project description:Several randomized controlled trials (RCTs) evaluated the afatinib efficacy in patients with advanced non-small cell lung cancer (NSCLC) and recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC). This review systemically outlined and meta-analyzed the afatinib efficacy in NSCLC and R/M HNSCC in terms of overall survival (OS) and progression-free survival (PFS) endpoints. Records were retrieved from PubMed, Web of Science, and ScienceDirect from 2011 to 2020. Eight afatinib RCTs were included and assessed for the risk of bias. In meta-analysis, overall pooled effect size (ES) of OS in afatinib group (AG) significantly improved in all RCTs and NSCLC-RCTs [hazard ratios (HRs): 0.89 (95% CI: 0.81-0.98, p = 0.02); I2 = 0%, p = 0.71/ 0.86 (95% CI: 0.76-0.97; p = 0.02); I2 = 0%, p = 0.50, respectively]. ES of PFS in AG significantly improved in all RCTs, NSCLC-RCTs, and HNSCC-RCTs [HRs: 0.75 (95% CI: 0.68-0.83; p < 0.00001); I2 = 26%, p = 0.24; 0.75 (95% CI: 0.66-0.84; p < 0.00001); I2 = 47%, p = 0.15/0.76 (95% CI: 0.65-88; p = 0.0004); I2 = 34%, p = 0.0004, respectively]. From a clinical viewpoint of severity, interstitial lung disease, dyspnea, pneumonia, acute renal failure, and renal injury were rarely incident adverse events in the afatinib group. In conclusion, first- and second-line afatinib monotherapy improved the survival of patients with NSCLC, while second-line afatinib monotherapy could be promising for R/M HNSCC. The prospective protocol is in PROSPERO (ID = CRD42020204547).

Nivolumab in the treatment of metastatic squamous non-small cell lung cancer: a review of the evidence.

Project description:Progress in the treatment of patients with advanced stage squamous cell non-small cell lung cancer (NSCLC) has been limited. An improvement in the understanding of tumor immunosurveillance has resulted in the development of the immune checkpoint inhibitors such as nivolumab. Nivolumab (Opdivo(®)), a human immunoglobulin (Ig)G4 anti-programmed death (PD)-1 monoclonal antibody, was the first PD-1 inhibitor approved in the treatment of patients with advanced stage squamous cell NSCLC following platinum-based chemotherapy. CHECKMATE 017, a randomized phase III study of second-line nivolumab versus docetaxel, significantly improved overall survival (OS), progression-free survival (PFS), patient reported outcomes and the safety and tolerability favored patients treated with nivolumab. The ligand (PD-L1) expression did not predict for outcome. In this paper, we review the role of nivolumab in the treatment of NSCLC with particular attention on recent studies, ongoing combination studies, toxicity profile, current and potential predictive biomarkers.

Spotlight on fevipiprant and its potential in the treatment of asthma: evidence to date.

Project description:Asthma is a heterogeneous disease, which may be classified into phenotypes and endotypes based on clinical characteristics and molecular mechanisms. The best described endotype of severe asthma is type 2 (T2)-high asthma, characterized by release of inflammatory cytokines by T helper 2 (TH2) cells and type 2 innate lymphoid cells cells. Prostaglandin D2 contributes to T2 inflammation through binding of the G-protein-coupled receptor chemoattractant receptor-homologous molecule expressed on TH2 cells (CRTH2). Fevipiprant is an oral competitive antagonist of CRTH2. Early-phase trials have demonstrated safety and potential efficacy in patients with asthma, specifically, improvement in FEV1 and eosinophilic airway inflammation. However, no clear biomarker identified patients who responded favorably to fevipiprant, although patients with moderate-to-severe asthma and evidence of T2 inflammation may be more likely to respond to treatment. Additional studies are needed to determine the efficacy and target population for use of this drug in patients with asthma.
