Combining Immunotherapy Agents in NSCLC: Is MYSTIC a Misstep? Combining Immunotherapy Agents in NSCLC: Is MYSTIC a Misstep?

Though they have received a lot of hype as the heir apparent in lung cancer therapy, the early signals on combining immunotherapies are not reassuring, cautions Dr Jack West.Medscape Oncology

Authors: Oliveres H, Caglevic C, Passiglia F, Taverna S, Smits E, Rolfo C Abstract Despite new advances in therapeutics, lung cancer remains the first cause of mortality among different types of malignancies. To improve survival, different strategies have been developed such as chemotherapy combinations, targeted therapies and more recently immunotherapy. Immunotherapy is based on the capability of the immune system to differentiate cancer cells from normal cells to fight against the tumor. The two main checkpoint inhibitors that have been widely studied in non-small cell lung cancer (NSCLC) are PD-1/PD-L1 and CTLA...

AbstractBackgroundThe clinical efficacy observed with inhibitors of programed cell death 1/programed cell death ligand 1 (PD-L1/PD-1) in cancer therapy has prompted studies to characterize the immune response in several tumor types, including lung cancer. However, the immunological profile of non –small cell lung carcinoma (NSCLC) treated with neoadjuvant chemotherapy (NCT) is not yet fully characterized, and it may be therapeutically important. The aim of this retrospective study was to characterize and quantify PD-L1/PD-1 expression and tumor-associated immune cells (TAICs) in surgically resected NSCLCs from patien...

AbstractPurpose of ReviewThe landscape of lung cancer therapy has completely shifted in the last decade. From the surge of targeted therapy to the resurrection of immunotherapy, the need for adequate lung tissue specimen is critical to evaluate tumor specimens for predictive biomarkers for both types of therapies, hence, the importance of obtaining several samples via endoscopic bronchial ultrasound performed by pulmonologists or thoracic surgeons. Moreover, these novel therapies have also been associated with respiratory side effects which will require prompt evaluation and aggressive management by pulmonologists, oncolog...

Lung cancer is the second most common cancer and the leading cause of cancer-related deaths. Different targeted therapies and the introduction of immunotherapy have successfully improved outcome for patients with non-small lung cancer (NSCLC). Anti-angiogenic drugs are an essential component in the treatment of NSCLC patients. The vascular endothelial growth factor (VEGF)-A antibody bevacizumab is approved for first-line treatment of advanced-stage patients in combination with platinum-based chemotherapy. Ramucirumab, a VEGF receptor antibody, and nintedanib, an anti-angiogenic multi-tyrosine kinase inhibitor, are approved...

Abstract Recent advances in the treatment of melanoma and non-small cell lung cancer (NSCLC) by combining conventional therapies with anti-PD1/PD-L1 immunotherapies, have renewed interests in immunotherapy of cancer. The emerging concept of conventional cancer therapies combined with immunotherapy differs from the classical concept in that it is not simply taking advantage of their additive anti-tumor effects, but it is to use certain therapeutic regimens to condition the tumor microenvironment for optimal response to immunotherapy. To this end, low dose immunogenic chemotherapies, epigenetic modulators and inhibi...

Diversity helps to ensure equal access to new cancer therapies and better treatment for everyone. Cancer research is increasingly focused on classifying patients according to molecular profiles for particular groups. We provide a detailed molecular analysis from paired NSCLC tissues that identified differential coding and noncoding RNA expression in NSCLC from African Americans (AA) and European Americ...

Authors: Krishnamurthy A, Jimeno A Abstract In recent years, immunotherapy has come to the forefront as a major development in cancer treatment. Evasion of the immune system by tumor cells has been identified as one of the hallmarks of cancer and multiple therapies have been developed to counter this process. Programmed cell death 1 ligand 1 (PD-L1), a ligand to programmed cell death protein 1 (PD-1), is expressed by many cancer cells and the binding of PD-L1 to PD-1 results in the suppression of T-cell-mediated immune response against cancer cells. Atezolizumab is a monoclonal antibody that binds to PD-L1 and bloc...

Immune checkpoint inhibitors (ICIs) are antibodies that target key signalling pathways such as programmed death 1 (PD1)/programmed death-ligands 1 and 2 (PDL1 and PDL2) to improve anti-tumour immune responses. Until recently, nivolumab was the only ICI validated for advanced non-small-cell lung cancer (NSCLC) in a second-line treatment setting. Results from recent phase II and phase III randomised trials testing other ICIs have been presented. In Keynote-024, pembrolizumab, an anti-PD1 antibody, was reported to have great efficacy in the first-line treatment of PDL1  ≥ 50% tumours (30% of screened tumours), wi...

PD Abstract High-quality genomic analysis is critical for personalized pharmacotherapy in patients with cancer. Tumor-specific genomic alterations can be identified in cell-free DNA (cfDNA) from patient blood samples and can complement biopsies for real-time molecular monitoring of treatment, detection of recurrence, and tracking resistance. cfDNA can be especially useful when tumor tissue is unavailable or insufficient for testing. For blood-based genomic profiling, next-generation sequencing (NGS) and droplet digital PCR (ddPCR) have been successfully applied. The US Food and Drug Administration (FDA) recently ...

In recent years, there has been a deeper understanding of the mechanisms of immune evasion by cancer cells. This has led to the development of a number of immune checkpoint inhibitors for cancer therapy. The first inhibitor to be approved was ipilumumab, a monoclonal antibody that works to activate the immune system by targeting CTLA-4 (cytotoxic T-lymphocyte-associated protein 4), also known as CD152 (cluster of differentiation 152), a protein receptor that downregulates the immune system. Ipilimumab inhibits CTLA4, which is important for dampening T cell responses at the priming phase in lymph nodes, and is approved for ...
