The randomised, phase 3 CheckMate 816 trial (NCT02998528) evaluates the efficacy and safety of neoadjuvant therapy with nivolumab plus chemotherapy in patients with resectable NSCLC. Recently, results were presented of the first primary endpoint (pCR, defined as 0% viable tumour cells in lung and lymph nodes): median pCR was 24% in patients (n=179) treated with neoadjuvant nivolumab plus chemotherapy versus 2.2% in patients (n=179) treated with neoadjuvant chemotherapy (HR 13.94; 95% CI 3.49–55.75; P<0.0001) [1]. At the ASCO 2021 Annual Meeting, Dr Jonathan Spicer (McGill University, Canada) presented key surgical outcomes from the study [2].
Definitive surgery rates were 83% with nivolumab plus chemotherapy (n=149) versus 75% with chemotherapy alone (n=135). Reasons for cancelled surgery included disease progression (12 and 17 patients, respectively) and adverse events (2 patients in each arm). Adverse events were responsible for delays of surgery in 6 patients in the nivolumab plus chemotherapy arm and 9 patients in the chemotherapy arm. Minimally invasive surgery rates were 30% and 22%, and conversion from minimally invasive to open surgery rates were 11% and 16% for nivolumab plus chemotherapy and chemotherapy, respectively. Lobectomy was performed in 77% and 61% of patients, and pneumonectomy in 17% and 25% for nivolumab plus chemotherapy and chemotherapy, respectively.
A complete resection (R0) was achieved in 83% versus 78% of patients and median residual viable tumour (RVT) cells in the primary tumour bed were 10% versus 74% for nivolumab plus chemotherapy versus chemotherapy. There was no increase in median duration of surgery and length of hospitalisation between the two arms.
