“…The study conducted by Ricciuti et al, including patients with advanced NSCLC treated with nivolumab (n=195), showed significantly higher ORR (43.5% vs. 10.0%, p<0.0001) and DCR (70.5% vs. 18.1%, p<0.0001), as well as longer PFS and OS (HR=0.41, p<0.0001 and HR=0.33, p<0.0001) in patients with irAEs compared with patients without any (36). The results of the Cox multivariate model showed the following factors to be significant for PFS: any irAE (HR=0.48, p<0.0001), pulmonary (HR=0.56, p=0.038), gastrointestinal (HR=0.055, p=0.021), endocrine (HR=0.59, p=0.011) and skin irAEs (HR=0.57, p=0.031); significant factors for OS were: any irAE (HR=0.38, p<0.0001), pulmonary (HR=0.46, p=0.022), gastrointestinal (HR=0.50, p=0.045), endocrine (HR=0.45, p=0.001) and skin irAEs (HR=0.80, p=0.043) (36). A 6weeks landmark analysis showed a significant association of irAEs with OS (HR=0.55, p=0.021) and a 12-weeks landmark analysis showed an even deeper and statistically significant association with PFS (HR=0.48, p<0.0001) and OS (HR=0.40, p<0.0001) (36).…”
