Dr. Jack West reviews treatment options for patients with an EGFR activating mutation and acquired resistance but no T790M mutation, focusing on a clinical trial with the novel hypoxia-induced pan-HER inhibitor TH4000.

Dr. Jack West summarizes the rationale for testing immune checkpoint inhibitors as a first line treatment for patients with advanced NSCLC and highlights details of two trials testing this question.

Drs. Ben Solomon, Leora Horn, & Jack West assess the utility and limitations of "liquid biopsies", serum-based testing for molecular marker testing in lung cancer.

Drs. Leora Horn, Ben Solomon, & Jack West consider the merits of administering immune checkpoint inhibitors concurrently with standard first line chemotherapy or targeted therapy vs. sequential treatment.

Drs. Ben Solomon, Leora Horn, & Jack West consider whether immunotherapy might prove to be more problematic when given to a broader population of older and frail patients with advanced lung cancer.

Dr. Jack West asks the question of whether newer, more active ALK inhibitors such as alectinib should be used as first line therapy rather than for acquired resistance, including introducing the ALEX trial that is trying to answer this question.

Drs. Leora Horn, Ben Solomon, & Jack West review the potential rationale and possible limitations of combining different immuntherapy strategies with one another.

Drs. Leora Horn, Ben Solomon, & Jack West assess whether clinical factors such as being a never-smoker or having a driver mutation (EGFR, ALK, etc.) reliably predict minimal benefit from immunotherapy agents.

Dr. Jack West introduces the question of whether third generation EGFR tyrosine kinase inhibitors osimertinib and rociletinib should be used as first line therapy rather than for acquired resistance, including discussing key clinical trials on the topic.

Dr. Eddie Garon, UCLA, reviews the controversial question of whether PD-L1 expression is a reliable enough biomarker to be used to select patients to receive or not receive immune checkpoint inhibitor therapy in lung cancer.
