Dr. Ece Cali: Hello, and welcome to our 2025 ASCO Annual Meeting series, where we cover some of the top JCO papers published simultaneously with their abstract presentation at this year's meeting. I'm your host, Dr. Ece Cali, JCO Editorial Fellow, and I am joined by JCO Associate Editor, Dr. Tom Stinchcombe. In this episode, we will discuss the Journal of Clinical Oncology article and abstract presentation "Neoadjuvant Osimertinib for Resectable EGFR-Mutated Non–Small-Cell Lung Cancer.”

NeoADAURA is a randomized global phase III study investigating the efficacy of neoadjuvant osimertinib-containing regimens in patients with resectable EGFR-mutated stage II to IIIB non–small-cell lung cancer. 358 patients were randomized 1:1:1 to receive osimertinib plus chemotherapy, osimertinib monotherapy, or placebo plus chemotherapy in the neoadjuvant setting. The primary endpoint was major pathological response. Osimertinib plus chemotherapy and osimertinib alone demonstrated MPR rates of 26% and 25%, respectively, compared to 2% in the chemotherapy plus placebo arm with a p-value of less than 0.001.

Tom, can you please explain to our listeners how you interpret this data?

Dr. Thomas Stinchcombe: Great question. Yeah, I think to give a little context, obviously, chemotherapy and immunotherapies preoperatively is becoming the standard of care. However, patients with EGFR-mutant lung cancer generally have not responded to immunotherapy, and many of the trials excluded patients with known EGFR mutation. There have been smaller phase II trials that had looked at EGFR TKIs preoperatively, but none of these were definitive. So I think that this trial is a big trial, and I think some of the strengths are that it has osimertinib alone and chemotherapy with osimertinib arms as compared to the standard of chemotherapy.

I think it's going to be really interesting at the meeting to see how this is discussed by the discussant and also what the reaction is to its public presentation. And I think that's largely because there's an alternative paradigm now, surgical resection adjuvant osimertinib, that's available to patients. So I think this will be interesting to see what the reaction is to the induction
