Prospects and progress of atezolizumab in non-small cell lung cancer

Expert Opinion on Biological Therapy

Abstract

Immunotherapy has recently come to the forefront of oncology treatment as a potential means of combating cancer by restoring the body's adaptive cancer-immunity cycle. Atezolizumab is a monoclonal antibody agent that specifically targets programmed death ligand 1 (PD-L1), a key molecule in the cancer-immunity pathway, to block binding to its receptors PD-1 and B7.1. Areas covered: This review covers the role of atezolizumab in the treatment of non-small-cell lung cancer (NSCLC). Several studies have reported promising efficacy in this indication. The phase II FIR and BIRCH studies evaluated atezolizumab monotherapy across different lines of therapy in NSCLC selected by PD-L1 expression status. The randomized POPLAR and OAK trials of atezolizumab versus docetaxel in previously treated NSCLC reported improved efficacy in the atezolizumab arm. Several ongoing studies yet to report data are also described and treatment-related adverse events are discussed. Expert opinion: Clinical trials have shown that atezolizumab has a favorable risk-benefit ratio compared with standard chemotherapy in second-line treatment of non-oncogene-driven advanced NSCLC. Promising response rates and survival over 2 years has been reported in the first-li...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
