Phase III CheckMate -816 trial of neoadjuvant treatment Opdivo shows benefits in non-small cell lung cancer.

With a minimum follow-up of 21.0 months, Opdivo with chemotherapy reduced the risk of disease recurrence, progression or death by 37% (Hazard Ratio [HR] 0.63; 97.38% Confidence Interval [CI]: 0.43 to 0.91; p=0.0052) across randomized patients when administered before surgery. In patients receiving the combination, median EFS was 31.6 months, compared to 20.8 months for patients treated with chemotherapy alone.

Additionally, while the data are still immature and the analysis did not reach statistical significance, favorable early overall survival (OS) results were observed with Opdivo in combination with chemotherapy (HR 0.57; 99.67% CI: 0.30 to 1.07). At two years, 83% of patients treated with neoadjuvant Opdivo and chemotherapy were alive, compared to 71% with chemotherapy alone. OS will continue to be followed for upcoming analyses.

CheckMate -816 represents the first Phase III study with an immunotherapy-based combination to show a significant improvement in EFS, as well as in the other primary endpoint of pathologic complete response (pCR), in the neoadjuvant setting of NSCLC. The EFS data are being presented for the first time during the Neoadjuvant and Perioperative Immunotherapy Clinical Trials Plenary Session (Abstract #CT012) at the American Association for Cancer Research (AACR) Annual Meeting 2022 on Monday, April 11, 2022, from 10:15 a.m. to 12:15 p.m. CT and simultaneously published in The New England Journal of Medicine.
