The Era of Antibody Drug Conjugates in Lung Cancer: Trick or Threat?

Antibody Drug Conjugates (ADCs) are a novel class of therapeutics that structurally are composed by an antibody directed to a tumour epitope connected via a linker to a cytotoxic payload, and that have shown significant antitumor activity across a range of malignancies including lung cancer. In this article we review the pharmacology and design of ADCs, as well as we describe the results of different studies evaluating ADCs in lung cancer directed to several targets including HER2, HER3, TROP2, MET, CEACAM5 and DLL3, among others.

Kinetics of IFNγ-Induced Cytokines and Development of Immune-Related Adverse Events in Patients Receiving PD-(L)1 Inhibitors.

Immune checkpoint inhibitors (ICI) have the potential to trigger unpredictable immune-related adverse events (irAEs), which can be severe. The underlying mechanisms of these events are not fully understood. As PD-L1 is upregulated by IFN, the heightened immune activation resulting from PD-1/PD-L1 inhibition may enhance the IFN response, triggering the expression of IFN-inducible genes and contributing to irAE development and its severity.

Association Between Lung Immune Prognostic Index and Durvalumab Consolidation Outcomes in Patients With Locally Advanced Non-Small-Cell Lung Cancer.

Introduction: The LIPI, based on pretreatment derived neutrophils/[leukocytes-neutrophils] ratio (dNLR) and LDH, is associated with immune checkpoint inhibitors (ICI) outcomes in advanced non-small-cell lung cancer (NSCLC). We aimed to assess baseline LIPI correlation with durvalumab consolidation outcomes in the locally advanced setting.

An update on lorlatinib: a novel first line treatment for -positive advanced lung cancer.

Introduction: Anaplastic lymphoma kinase () tyrosine kinase inhibitors (TKIs) have significantly improved the prognosis of -rearranged non-small cell lung cancer (NSCLC), but these patients will eventually develop resistance and progression of disease after 10 months of first-generation and more than 30 months after second-generation TKIs. Lorlatinib is a third-generation highly selective ALK-TKI capable of inducing significant and durable CNS responses and overcoming known resistance mutations.

Areas Covered: This review summarizes the mechanism of action, efficacy, and safety of lorlatinib in -positive NSCLC.

Unexpected Cardiotoxicity in Patients With -Mutant NSCLC Treated With Trastuzumab Deruxtecan: A Case Report.

Antibody-drug conjugates targeting receptor tyrosine-protein kinase erbB-2 () have emerged as promising targeted options for -mutant NSCLC. Among antibody-drug conjugates targeting HER2, trastuzumab deruxtecan was found to have the most impressive efficacy and is a potential new standard of care. Drug-related interstitial lung disease remains a serious unpredictable identified risk for patients treated with trastuzumab deruxtecan, requiring careful monitoring and multidisciplinary management.

Radon and Lung Cancer: Current Trends and Future Perspectives.

Lung cancer is a public health problem and the first cause of cancer death worldwide. Radon is a radioactive gas that tends to accumulate inside homes, and it is the second lung cancer risk factor after smoking, and the first one in non-smokers. In Europe, there are several radon-prone areas, and although the 2013/59 EURATOM directive is aimed to regulate indoor radon exposition, regulating measures can vary between countries.

Targeting molecular alterations in non-small-cell lung cancer: what's next?

In recent years, major advances have been achieved in our understanding of non-small-cell lung cancer (NSCLC) with oncogenic driver alterations and in the specific treatment of these with tyrosine kinase inhibitors. Currently, state-of-the-art management of patients with NSCLC (particularly adenocarcinoma or non-adenocarcinoma but with mild tobacco exposure) consists of the determination of , ,  and status, as they have US FDA and EMA approved targeted therapies. The increase in molecular knowledge of NSCLC and the development of drugs against other targets has settled new therapeutic indications.

Targeting BRAF-mutant non-small cell lung cancer: Current status and future directions.

Lung cancer harbouring BRAF mutations accounts for 4% of all non-small cell lung cancer (NSCLC) cases, identifying a relevant subset of patients that need to be promptly managed. Three subtypes of BRAF mutations have been described: class I (V600E), and class II and III (non-V600), with different prognostic and predictive outcomes. Pivotal phase II trials have demonstrated the efficacy of the double BRAF/MEK inhibition with dabrafenib plus trametinib in patients harbouring V600E mutations, making BRAF a mandatory requirement in the genetic portrait of advanced non-squamous lung cancer patients.

Clinical Utility and Outcomes Impact of Crystal Digital PCR of Sensitizing and Resistance EGFR Mutations in Patients With Advanced Non-Small Cell Lung Cancer.

Background: EGFRm represent 15% of advanced NSCLC in European patients. LB for molecular profiling offers a non-invasive alternative to tissue. cdPCR is a high-sensitive and low-cost LB to detect molecular alterations.

Complete Remission After Immunotherapy-Induced Abdominal Tuberculosis in a Patient With Advanced NSCLC Treated With Pembrolizumab: A Case Report.

The use of immune checkpoint inhibitors (ICIs) has drastically transformed the therapeutic landscape in lung cancer. Special focus has been put on immune-related toxicity; however, infections can also seem during ICI treatment. Although rare, tuberculosis (TB) has been increasingly identified after ICIs, and it seems that the programmed cell death protein 1 and programmed death-ligand 1 pathway is directly involved in its pathophysiology.

Durvalumab consolidation in patients with unresectable stage III non-small cell lung cancer with driver genomic alterations.

Introduction: Durvalumab is the standard-of-care as consolidation therapy after chemo-radiotherapy in stage III unresectable non-small cell lung cancer (NSCLC); however, its activity across patients with NSCLC harbouring driver genomic alterations (dGA) is poorly characterised.
