Dr. Luis Raez, MD FACP FCCP, Chief of Hem/Onc and Med. Dir. at Memorial Cancer Institute, and Clinical Associate Prof. of Medicine at FL International U. joined GRACE to discuss biomarkers for predicting activity of immune checkpoint inhibitors.

The current standard of care for SCLC shows limited results with high toxicities. Drs. Soria, Gandhi, and West discuss new ASCO 2015 data that show promise for a subset of patients with PD-L1 expression on Keytruda (pembrolizumab) or Opdivo (nivolumab).

As more immunotherapeutics become available to treat lung cancer, research must determine how to balance efficacy, toxicities, and cost. That means finding which patients who will benefit from which drugs while maintaining good quality of life.

Novel immunotherapy agent atezolizumab (MPDL3280A) looks superior to Taxotere (docetaxel) in a study, specifically for patients with PD-L1. What are the implications of multiple agents with similar mechanisms of action in the same clinical settings?

The immune checkpoint inhibitor Opdivo (nivolumab) shows better efficacy than Taxotere (docetaxel) for advanced non-squamous NSCLC, but this was seen only in patients with PD-L1 protein expression on their tumor. Should we be using this as a biomarker?

Research released at the 2015 American Society of Clinical Oncology (ASCO) annual meeting showed great promise for squamous cell lung cancer patients taking the immunotherapy drug Opdivo (nivolumab). But can we predict which patients will do well on it?

Continuing with the analysis of a publication about tarceva (erlotinib) for patients with advanced BAC that I introduced in the last post, we'll turn now to the analysis that Dr. Vince Miller and colleagues did on the biomarkers that might predict more or less clinical benefit with an EGFR inhibitor like tarceva (abstract here).

An interesting article just came out in the Journal of Clinical Oncology from researchers at Duke, led by Dr. Ed Patz of the Radiology Department there (abstract here).
