Another KRAS G12C inhibitor. Congrats to FCS Director of Drug Development Manish Patel, MD, one of the authors. Durable responses with less adverse events.
Perioperative Nivolumab and Chemotherapy in Stage III Non–Small-Cell Lung Cancer
Dr. Anjan Patel's Thoughts
The NADIM-II study looked at perioperative Nivo+chemo vs. chemo alone in stIIIA – stIIIB NSCLC. High pCR rates with chemoIO are again seen, as in the Checkmate 816 and NADIM-I study, they were even higher in this cohort (37%), suggesting higher-stage patients derive the biggest benefit from neoadjuvant chemoIO. Pretty impressive results, however, I still must point out that this was a phase II study with a small sample size, OS benefits have not been demonstrated and this has yet to make it on to NCCN.
Approximately 20% of patients with non–small-cell lung cancer (NSCLC) receive a diagnosis of stage III disease. There is no current consensus regarding the most appropriate treatment for these patients.
In this open-label, phase 2 trial, we randomly assigned patients with resectable stage IIIA or IIIB NSCLC to receive neoadjuvant nivolumab plus platinum-based chemotherapy (experimental group) or chemotherapy alone (control group), followed by surgery. Patients in the experimental group who had R0 resections received adjuvant treatment with nivolumab for 6 months. The primary end point was a pathological complete response (0% viable tumor in resected lung and lymph nodes). Secondary end points included progression-free survival and overall survival at 24 months and safety.
A total of 86 patients underwent randomization; 57 were assigned to the experimental group and 29 were assigned to the control group. A pathological complete response occurred in 37% of the patients in the experimental group and in 7% in the control group (relative risk, 5.34; 95% confidence interval [CI], 1.34 to 21.23; P=0.02). Surgery was performed in 93% of the patients in the experimental group and in 69% in the control group (relative risk, 1.35; 95% CI, 1.05 to 1.74). Kaplan–Meier estimates of progression-free survival at 24 months were 67.2% in the experimental group and 40.9% in the control group (hazard ratio for disease progression, disease recurrence, or death, 0.47; 95% CI, 0.25 to 0.88). Kaplan–Meier estimates of overall survival at 24 months were 85.0% in the experimental group and 63.6% in the control group (hazard ratio for death, 0.43; 95% CI, 0.19 to 0.98). Grade 3 or 4 adverse events occurred in 11 patients in the experimental group (19%; some patients had events of both grades) and 3 patients in the control group (10%).
In patients with resectable stage IIIA or IIIB NSCLC, perioperative treatment with nivolumab plus chemotherapy resulted in a higher percentage of patients with a pathological complete response and longer survival than chemotherapy alone.

Neoadjuvant chemotherapy trial with post op nivolumab for 6 months shows promising results.
First-line atezolizumab monotherapy versus single-agent chemotherapy in patients with non-small-cell lung cancer ineligible for treatment with a platinum-containing regimen (IPSOS): a phase 3, global, multicentre, open-label, randomised controlled study
Patients with poor performance status do better on atezolizumab monotherapy vs. single agent chemotherapy.
Phase II, Open-Label Study of Encorafenib Plus Binimetinib in Patients With BRAFV600-Mutant Metastatic Non–Small-Cell Lung Cancer
Targeted therapy in NSCLC, FCS was part of this trial.
The ADAURA trial reported its 5-year data at the plenary session of ASCO. No surprise, given the 3-year data was very compelling, adjuvant Osimertinib should be considered SOC for EGFR-mutated stage IB – IIIA NSCLC patients.
