Management of Stage III NSCLC Rapid Update

Dr. Megan Daly presents the latest rapid recommendation update to the ASCO management of stage III NSCLC guideline, based on data from the phase III randomized LAURA trial, presented at the 2024 ASCO Annual Meeting, and subsequently published. She discusses the results of the trial, shares the updated recommendation from the expert panel, and the impact for both clinicians and patients. We also discuss future research in the area and exciting new developments to watch out for in the field.

Brittany Harvey: Hello and welcome to the ASCO Guidelines podcast, one of ASCO’s podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one at asco.org/podcasts.

My name is Brittany Harvey, and today I'm interviewing Dr. Megan Daly from the University of California Davis Comprehensive Cancer Center, lead author on, “Management of Stage III Non–Small-Cell Lung Cancer: ASCO Rapid Guideline Update.”

Thank you for being here today, Dr. Daly.

Dr. Megan Daly: Thanks for having me, Brittany.

Brittany Harvey: Great. Then before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Daly, who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes.

So then, to start us off on the content of this update, first, this guideline was updated based off new evidence presented at the 2024 ASCO Annual Meeting. Dr. Daly, could you describe the trial that prompted this rapid update to the management of stage III non-small cell lung cancer guideline?

Dr. Megan Daly: The trial that prompted this update is the LAURA trial. The LAURA trial was a phase III randomized trial conducted in patients with unresectable stage III non-small cell lung cancer harboring EGFR mutations, either exon 19 deletions or L858R insertions. Patients in this trial were randomized 2:1 between the third generation EGFR tyrosine kinase inhibitor osimertinib or placebo, and osimertinib or placebo were continued until progression or other reasons for discontinuation. Osimertinib was found to provide a considerable benefit in progression free survival, with a hazard ratio of 0.16. The median progression free survival for patients randomized to osimertinib was 39.1 months, and for patients on the placebo arm, it was 5.6 months. We did not yet have overall survival data from the LAURA trial. The data is not mature, but the considerable progression free survival benefit noted with osimertinib has drawn a lot of interest to this trial.

Brittany Harvey: Absolutely. Thank you for describing the results of those trials and the endpoints. So then, based on this new evidence, what is the updated recommendation from the guideline ex
