Current and future biomarkers for outcomes with immunotherapy in non-small cell lung cancer.

ABSTRACT: Immune checkpoint inhibitors (ICI) have been validated as an effective new treatment strategy in several tumoral types including lung cancer. This remarkable shift in the therapeutic paradigm is in large part due to the duration of responses and long-term survival seen with ICI. However, despite this, the majority of cancer patients do not experience benefit from ICI. Even among patients who initially respond to ICI, disease progression may ultimately occur. Moreover, in some patients, these drugs may be associated with new patterns of progression such as pseudo-progression and hyper-progressive disease, and different toxicity profiles with immune-related adverse events. Therefore, the identification of predictive biomarkers may help to select those patients most likely to obtain a true benefit from these drugs, and avoid exposure to potential toxicity in patients who will not obtain clinical benefit, while also reducing the economic impact. In this review, we summarize current and promising potential predictive biomarkers of ICI in patients with non-small cell lung cancer (NSCLC), as well as pitfalls encountered with their use and areas of focus to optimize their routine clinical implementation.

Project description:Lung cancer is the leading cause of cancer mortality and non-small cell lung cancer (NSCLC) accounts for more than 85% of all lung cancers. Platinum-based doublet chemotherapy is the standard first-line treatment for metastatic NSCLC when genomic testing reveals no targetable alteration such as epidermal growth factor receptor (EGFR) mutations, anaplastic lymphoma kinase (ALK) or ROS1 translocation/re-arrangements. But, chemotherapy produces response rates ranging only between 15-30%. For patients whose disease progresses on first-line chemotherapy, second-line therapy historically consists of taxane-based salvage chemotherapy with a response rate of less than 25%. Recently, immunotherapy with checkpoint inhibitor agents have demonstrated responses in advanced NSCLC, with some patients exhibiting durable responses after discontinuing therapy. In 2015, two immune checkpoint inhibitors targeting programmed cell death-1 (PD-1), nivolumab and pembrolizumab were approved for second-line therapy of NSCLC. In 2016, another checkpoint inhibitor targeting program death-ligand 1 (PD-L1), atezolizumab was approved for the same indication. Moreover, pembrolizumab also received approval in 2016 for first-line NSCLC treatment in patients with high PD-L1 expressing tumors. Immunotherapy for NSCLC has therefore, recently evolved into a true treatment modality with the acceptance of PD-1 and PD-L1 inhibitors as the new standard of care for second-line treatment. However, it is still at the discretion of the treating physician whether to use PD-1 or PD-L1 inhibitor as data to compare these two pathways is lacking. Focus is now also on exploring their role in the adjuvant and consolidation settings for NSCLC as well as on exploring novel combinations combining these agents with chemotherapy or radiation. Research is also needed in the development of predictive and prognostic biomarkers for these agents. While vaccine therapy trials in NSCLC have so far failed to show significant clinical benefit, the demonstration of enhanced immune response in these trials suggest the vaccine therapy needs additional evaluation in combination with other therapeutic modalities especially checkpoint inhibition.
